Authors: George Rajna
Comments: 50 Pages.

In a new study, physicists at Radboud University have demonstrated that this could also be achieved by using chips whose operation is inspired by that of the human brain. [29] A team of researchers from the University of Münster, the University of Oxford and the University of Exeter has built an all-optical neural network on a single chip. [28] Physicists from Petrozavodsk State University have proposed a new method for oscillatory neural network to recognize simple images. Such networks with an adjustable synchronous state of individual neurons have, presumably, dynamics similar to neurons in the living brain. [27] Navid Borhani, a research-team member, says this machine learning approach is much simpler than other methods to reconstruct images passed through optical fibers, which require making a holographic measurement of the output.

Superfast Computing by Light Pulses

Authors: George Rajna
Comments: 46 Pages.

Superfast data processing using light pulses instead of electricity has been created by scientists. [27] Yao-Lung (Leo) Fang, an assistant computational scientist with the Quantum Computing Group in Brookhaven's Computational Science Initiative and a co-author of the paper, explained that a particle occupying a stable bound state is confined in space, such as an electron orbiting a hydrogen atom. [26] MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers. [25] Operation at the single-photon level raises the possibility of developing entirely new communication and computing devices, ranging from hardware random number generators to quantum computers. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21] Engineers at Australia's University of New South Wales have invented a radical new architecture for quantum computing, based on novel 'flip-flop qubits', that promises to make the large-scale manufacture of quantum chips dramatically cheaper-and easier-than thought possible. [20] A team of researchers from the U.S. and Italy has built a quantum memory device that is approximately 1000 times smaller than similar devices-small enough to install on a chip. [19] The cutting edge of data storage research is working at the level of individual atoms and molecules, representing the ultimate limit of technological miniaturisation. [18] This is an important clue for our theoretical understanding of optically controlled magnetic data storage media. [17]

Authors: George Rajna
Comments: 72 Pages.

Design and his collaborators developed a novel approach to untangle the centralization phenomena in blockchain mining. [42] Cryptography is often used in information technology security environments to protect sensitive, high-value data that might be compromised during transmission or while in storage. [41] In a step forward for information security for the Internet of Things, a team of researchers has published a new paper in the online edition of Nano Letters in which they have engineered a new type of physically unclonable function (PUF) based on interfacial magnetic anisotropy energy (IAE). [40] Researchers from Linköping University and the Royal Institute of Technology in Sweden have proposed a new device concept that can efficiently transfer the information carried by electron spin to light at room temperature-a stepping stone toward future information technology. [39] Now writing in Light Science & Applications, Hamidreza Siampour and co-workers have taken a step forward in the field of integrated quantum plasmonics by demonstrating on-chip coupling between a single photon source and plasmonic waveguide. [38] Researchers at University of Utah Health developed a proof-of-concept technology using nanoparticles that could offer a new approach for oral medications. [37] Using scanning tunneling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. [36] A fiber optic sensing system developed by researchers in China and Canada can peer inside supercapacitors and batteries to observe their state of charge. [35] The idea of using a sound wave in optical fibers initially came from the team's partner researchers at Bar-Ilan University in Israel. Joint research projects should follow. [34]

Blockchain for Science: Bloxberg

Authors: George Rajna
Comments: 45 Pages.

Securing scientific information online and worldwide with no risk of manipulation is now possible, thanks to the decentralized blockchain infrastructure Bloxberg. [26] A new type of money that allows users to make decisions based on information arriving at different locations and times, and that could also protect against attacks from quantum computers, has been proposed by a researcher at the University of Cambridge. [25] Shortcomings of security breach notifications, best practices for phishing warnings and lessons learned from the use of analytics to improve student performance are among several studies University of Michigan researchers will present beginning this weekend in the United Kingdom. [24] But moral questions about what data should be collected and how it should be used are only the beginning. [23] A self-driving vehicle has to detect objects, track them over time, and predict where they will be in the future in order to plan a safe manoeuvre. [22] In order to improve world food conditions, a team around computer science professor Kristian Kersting was inspired by the technology behind Google News. [21] Small angle X-ray scattering (SAXS) is one of a number of biophysical techniques used for determining the structural characteristics of biomolecules. [20] A deep neural network running on an ordinary desktop computer is interpreting highly technical data related to national security as well as-and sometimes better than-today's best automated methods or even human experts.

Quasi-Particles Computing

Authors: George Rajna
Comments: 59 Pages.

These exotic particles can, for example, emerge as quasi-particles in topological superconductors and represent ideal building blocks for topological quantum computers. [35] This event is considered as a striking proof of the existence of Majorana particles, and it represents a crucial step towards their use as building blocks for the development of quantum computers. [34] In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. [33] With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. [32] A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface. [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28] A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25]

Silicon Switches to Compute

Authors: George Rajna
Comments: 76 Pages.

Logic and memory devices, such as the hard drives in computers, now use nanomagnetic mechanisms to store and manipulate information. [47] Physicists at the University of Alberta in Canada have developed a new way to build quantum memories, a method for storing delicate quantum information encoded into pulses of light. [45] Now, an Australian research team has experimentally realised a crucial combination of these capabilities on a silicon chip, bringing the dream of a universal quantum computer closer to reality. [44] A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. [43] As the number of hacks and security breaches rapidly climbs, scientists say there may be a way to make a truly unhackable network by using the laws of quantum physics. [42] This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' HYPERLINK "https://phys.org/tags/light/" light. [41] Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers.

Electroacoustic Magnon Computer Memory

Authors: George Rajna
Comments: 73 Pages.

Computer memory could become faster and cheaper thanks to research into a promising class of materials by University of Arkansas physicists. [44] There's little doubt the information technology revolution has improved our lives. But unless we find a new form of electronic technology that uses less energy, computing will become limited by an "energy crunch" within decades. [43] Researchers at the Niels Bohr Institute, University of Copenhagen, have recently succeeded in boosting the storage time of quantum information, using a small glass container filled with room temperature atoms, taking an important step towards a secure quantum encoded distribution network. [42] New work by a team at the University of Bristol's Centre for Quantum Photonics has uncovered fundamental limits on the quantum operations which can be carried out with postselection. [41] The experimental investigation of ultracold quantum matter makes it possible to study quantum mechanical phenomena that are otherwise inaccessible. A new test to spot where the ability to exploit the power of quantum mechanics has evolved in nature has been developed by physicists at the University of Warwick. [38] A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. [37] Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. [36] JILA scientists have invented a new imaging technique that produces rapid, precise measurements of quantum behavior in an atomic clock in the form of near-instant visual art. [35]

Fast Frame Rate Up-conversion Using Video Decomposition

Authors: Nikhil Singh, Saumik Bhattachary
Comments: 7 Pages.

Video is one of the most popular media in the world. However, video standards that are followed by different broadcasting companies and devices differ in several parameters. This results in compatibility issues in different hardware while handling a particular video type. One of such major, yet important parameter is frame rate of a video. Though it is easy to reduce the frame rate of a video by dropping frames at a particular interval, frame rate up-conversion is a non-trivial yet important problem in video communication. In this paper, we apply video decomposition algorithm to extract the moving regions in a video and interpolate the background and the sparse information separately for a fast up-conversion. We test our algorithm for different video contents and establish that the proposed algorithm performs faster than the existing up-conversion method without producing any visual distortion.

Secure Symmetric Key Exchange

Authors: Michel SJ Kuipers
Comments: Pages.

Exchanging a secret password or key over an insecure communication line (symmetric key exchange) traditionally always causes the problem that a man-in-the-middle can eavesdrop the communication between the two parties and the intercepted data together with the known algorithm provides a way to deduce the password, making every attempt insecure. The solution is to use asymmetric key exchange using very complex mathematical formulas which are almost impossible to inverse, invented by Diffie and Hellman. This article proposes a new invention which is very simple and elegant, and fast to compute, which should make symmetric key exchange logically proven safe (unhackable) and easy to use, solving this old problem in perpetuity.

Materials Improve Data Storage

Authors: George Rajna
Comments: 47 Pages.

A new study provides insight into multiferroic materials, which could have substantive implications in fields such as data storage. [30] Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity. [29] Researchers have discovered that using an easily made combination of materials might be the way to offer a more stable environment for smaller and safer data storage, ultimately leading to miniature computers. [28] demonstrated an original layout of a prototype of multiresonator broadband quantum-memory interface. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

An Analysis of Noise Folding for Low-Rank Matrix Recovery

Authors: Jianwen Huang, Jianjun Wang, Feng Zhang, Et Al.
Comments: 19 Pages.

Previous work regarding low-rank matrix recovery has concentrated on the scenarios in which the matrix is noise-free and the measurements are corrupted by noise. However, in practical application, the matrix itself is usually perturbed by random noise preceding to measurement. This paper concisely investigates this scenario and evidences that, for most measurement schemes utilized in compressed sensing, the two models are equivalent with the central distinctness that the noise associated with (\ref{eq.3}) is larger by a factor to $mn/M$, where $m,~n$ are the dimension of the matrix and $M$ is the number of measurements. Additionally, this paper discusses the reconstruction of low-rank matrices in the setting, presents sufficient conditions based on the associating null space property to guarantee the robust recovery and obtains the number of measurements. Furthermore, for the non-Gaussian noise scenario, we further explore it and give the corresponding result. The simulation experiments conducted, on the one hand show effect of noise variance on recovery performance, on the other hand demonstrate the verifiability of the proposed model.

On the In-Band Full-Duplex Gain Scalability in On-demand Spectrum Wireless Local Area Networks

Authors: Saulo Queiroz
Comments: 126 Pages. PhD Thesis

The advent Self-Interference Cancellation (SIC) techniques has turned in-band Full-Duplex (FD) radios into a reality. FD radios doubles the theoretical capacity of a half-duplex wireless link by enabling simultaneous transmission and reception in the same channel. A challenging question raised by that advent is whether it is possible scale the FD gain in Wireless Local Area Networks (WLANs). Precisely, the question concerns on how a random access Medium Access Control (MAC) protocol can sustain the FD gain over an increasing number of stations. Also, to ensure bandwidth resources match traffic demands, the MAC protocol design is also expected to enable On-Demand Spectrum Allocation (ODSA) policies in the presence of the FD feature. In this sense, we survey the related literature and find out a coupled FD-ODSA MAC solution lacks. Also, we identify a prevailing practice for the design of FD MAC protocols we refer to as the 1:1 FD MAC guideline. Under this guideline, an FD MAC protocol ‘sees’ the whole FD bandwidth through a single FD PHYsical (PHY) layer. The protocol attempts to occupy the entire available bandwidth with up to two arbitrary simultaneous transmissions. With this, the resulting communication range impair the spatial reuse offer which penalizes network throughput. Also, modulating each data frame across the entire wireless bandwidth demands stronger Received Signal Strength Indication (RSSI) (in comparison to narrower bandwidths). These drawbacks can prevent 1:1 FD MAC protocols to scale the FD gain. To face these drawbacks, we propose the 1:N FD MAC design guideline. Under the 1:N guideline, FD MAC protocols ‘see’ the FD bandwidth through N >1 orthogonal narrow-channel PHY layers. Channel orthogonality increases spatial reuse offer and narrow channels relaxes RSSI requisites. Also, the multi-channel arrangement we adopt facilitates the development of ODSA policies at the MAC layer. To demonstrate how an FD MAC protocol can operate under the 1:N design guideline, we propose two case studies. A case study consists of a novel random access protocol under the 1:N design guideline called the Piece by Piece Enhanced Distributed Channel Access (PbP-EDCA). The other case study consists in adapting an existing FD Wi-Fi MAC protocol [Jain et al., 2011]) – we name as the 1:1 FD Busy Tone MAC protocol (FDBT) – to the 1:N design guideline. Through analytical performance evaluation studies, we verify the 1:N MAC protocols can outperform the 1:1 FDBT MAC protocol’s saturation throughput even in scenarios where 1:1 FDBT is expected to maximize the FD gain. Our results indicate that the capacity upper-bound of an arbitrary 1:1 FD MAC protocol improves if the protocol functioning can be adapted to work under the 1:N MAC design guideline. To check whether that assertion is valid, we propose an analytical study and a proof-of-concept software-defined radio experiment. Our results show the capacity upper-bound gains of both 1:1 and 1:N design guidelines corresponds to 2× and 2.2× the capacity upper-bound achieved by a standard half-duplex WLAN at the MAC layer, respectively. With these results, we believe our proposal can inspire a new generation of MAC protocols that can scale the FD gain in WLANs.

Improving Triangulation Accuracy in High-Velocity Systems

Authors: Michael Harney
Comments: 8 Pages.

Wireless tracking and triangulation approaches have existed for many decades, but the last decade has seen much more focus on efficiency and accuracy of triangulation which has translated into the use of fewer sensors and more efficient algorithms. In the case of tracking high-velocity objects, there is a necessity for accuracy as the error in a tracking system can accumulate quickly and a lock on the object can be lost and never recovered. In the following paper, we will discuss a method of tracking that uses the motion of an object as an advantage in tracking it, with a higher-velocity object providing more data points to allow for more accurate tracking.

Photons Trained for Optical Fiber

Authors: George Rajna
Comments: 51 Pages.

Researchers from the National University of Singapore (NUS) and Singtel, Asia's leading communications technology group, have demonstrated a technique that will help pairs of light particles smoothly navigate these networks, a breakthrough that will enable stronger cyber security. [36] Researchers of the Institute of Photonic Integration of the Eindhoven University of Technology (TU/e) have developed a 'hybrid technology' which shows the advantages of both light and magnetic hard drives. [35] Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms.

Comments: 21 Pages.

We present an innovative approach to the design of a decentralized asynchronous protocol that will, first, let business of any kind realize any project that can be formalized on a “step-bystep” basis, second, allow its users to completely solve Byzantine problem with one or many contracts-related associative network (subnetwork), third, allow business to design, if needed, a strictly economy-based model that can be stable for a long period of time. The innovative approach is totally based on the technology of Smart Transaction [1]. The protocol is mainly focused on a practical realization of economical business contracts of any kind.

Neurochain

Authors: Egger Mielberg
Comments: 12 Pages.

In a system where there are tons of information of different types it is always hard and frequently impossible to tie the effect to the cause. There is also a challenge to find relevant data quickly, especially in case of absence of classification algorithm that is capable of working with different fields of business and science in parallel. We propose a mechanism for building a network of associative chains that are decentralized to each other. The network allows its participants to build quickly an associative chain from “effect-tocause”. This feature of the network is extremely useful for identification of a scam activity. The mechanism is based on two technologies, “Smart Transactions” [1] and “Proof of Participation Protocol” [2].

As a symmetric as an asymmetric scheme requires a key (session or private) to be hidden. In this case, an attacker gets a chance and time for finding and decrypting it. As long as a secret has static attributes (length, type of characters, etc.) it will always be vulnerable for an attack. We propose a new concept of keyless encryption, “Amorphic scheme”, which is semantically secured and has “Perfect Secrecy” level. It allows a secret to be transmitted over any public channel with no public or private key to be generated and stored.

Neuro-Amorphic Construction Algorithm (NACA)

Authors: Egger Mielberg
Comments: 12 Pages.

Under certain circumstances, determinism of a block cipher can lead to a disclosure of sensitive information about working mechanism of underlying machine. Unveiled restrictions of the mechanism can also give a possibility for an adversary to brute-force the cipher at a reasonable period of time. We propose a nondeterministic algorithm operating on variable-length groups of bits with dynamically varying parts of round ciphertext. We named it as “Neuron Cipher”. It does not use as public as private key. In compared with symmetric or asymmetric encryption, it has obvious practical advantages. Among them is a “Perfect Secrecy” [4].

Authors: George Rajna
Comments: 51 Pages.

Blockchain as a technology is seeing tremendous innovation and is impacting almost all industries from supply chain to gaming and, perhaps the most recognizable, cryptocurrency. [28] At the Niels Bohr Institute, University of Copenhagen, researchers have realized the swap of electron spins between distant quantum dots. [27] A quantum circuit that can unambiguously test for information scrambling in an experiment could help verify the calculations of quantum computers and even shed more light on what happens to quantum information when it falls into a black hole.

Memristor Speeding Up AI

Authors: George Rajna
Comments: 44 Pages.

A group at Politecnico di Milano has developed an electronic circuit able to solve a system of linear equations in a single operation in the timescale of a few tens of nanoseconds. [26] We are still far off from achieving Quantum Advantage for machine learning-the point at which quantum computers surpass classical computers in their ability to perform AI algorithms. [25] Physicists in the US have used machine learning to determine the phase diagram of a system of 12 idealized quantum particles to a higher precision than ever before. [24] The research group took advantage of a system at SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) that combines machine learning-a form of artificial intelligence where computer algorithms glean knowledge from enormous amounts of data-with experiments that quickly make and screen hundreds of sample materials at a time. [23] Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones. [22] Such are the big questions behind one of the new projects underway at the MIT-IBM Watson AI Laboratory, a collaboration for research on the frontiers of artificial intelligence. [21]

Scaling Silicon Quantum Computers

Authors: George Rajna
Comments: 76 Pages.

Research collaboration between UNSW and the University of Sydney has overcome a fundamental hurdle to building quantum computers in silicon, opening the way to further develop the machines at scale. [42] Experimental photonic switches tested by researchers at the University of California, Berkeley, U.S.A., show promise toward the goal of fully optical, high-capacity switching for future high-speed data transmission networks. [41] Their research involved exploring how to exploit multicore fiber-optic technology that is expected to be used in future transmission networks. [40] When Greg Bowman presents a slideshow about the proteins he studies, their 3-D shapes and folding patterns play out as animations on a big screen. [39] Researchers at the University of Helsinki uncovered the mechanisms for a novel cellular stress response arising from the toxicity of newly synthesized proteins. [38] Scientists have long sought to develop drug therapies that can more precisely diagnose, target and effectively treat life-threatening illness such as cancer, cardiovascular and autoimmune diseases. [37] Skin cells taken from patients with a rare genetic disorder are up to ten times more sensitive to damage from ultraviolet A (AVA) radiation in laboratory tests, than those from a healthy population, according to new research from the University of Bath. [36] The use of stem cells to repair organs is one of the foremost goals of modern regenerative medicine. [35] Using new technology to reveal the 3-D organization of DNA in maturing male reproductive cells, scientists revealed a crucial period in development that helps explain how fathers pass on genetic information to future generations. [34] According to the Centers for Disease Control and Prevention, Down syndrome is the most common birth defect, occurring once in every 700 births. [33] Healing is a complex process in adult skin impairments, requiring collaborative biochemical processes for onsite repair. [32]

Average Modeling of Fly-Buck Converter

Authors: Denys I. Zaikin, Simon L. Mikkelsen, Stig Jonasen, Konstantin Sirenko
Comments: 4 Pages. Preliminary version. To be improved in the nearest future.

This document presents an average macro model for the fly-buck converter. The model can be used for both large and small signal modeling. Parasitic and lossy components are included in the model, and it is partially based on a conventional average switch model for a buck stage. For isolated output, the analytic solution of the average current in a secondary winding is proposed. The presented model is implemented in SPICE, and simulation results are compared to switching model simulation and experimental data.

Emerging NUI-based Methods for User Authentication: A New Taxonomy and Survey

Authors: Napa Sae-Bae, Jonathan Wu, Nasir Memon, Janusz Konrad, Prakash Ishwar
Comments: 28 Pages.

As the convenience and cost benefits of Natural User Interface (NUI) technologies are hastening their wide adoption, computing devices equipped with such interfaces are becoming ubiquitous. Used for a broad range of applications, from accessing email and bank accounts to home automation and interacting with a healthcare provider, such devices require, more than ever before, a secure yet convenient user authentication mechanism. This paper introduces a new taxonomy and presents a survey of “point-of-entry” user-device authentication mechanisms that employ a natural user interaction. The taxonomy allows a grouping of the surveyed techniques based on the sensor type used to capture user input, the actuator a user applies during interaction, and the credential type used for authentication. A set of security and usability evaluation criteria are then proposed based on the Bonneau, Herley, Van Oorschot and Stajano framework. An analysis of a selection of techniques and, more importantly, the broader taxonomy elements they belong to, based on these evaluation criteria, are provided. This analysis and taxonomy provide a framework for the comparison of different authentication alternatives given an application and a targeted threat model. Similarly, the taxonomy and analysis also offer insights into possibly unexplored, yet potentially rewarding, research avenues for NUI-based user authentication that could be explored.

Comments: 62 Pages.

Researchers from the Singapore University of Technology and Design (SUTD) have invented a new type of anti-counterfeiting technology called holographic colour prints for securing important documents such as identity cards, passports and banknotes. [36] Holography is a powerful tool that can reconstruct wavefronts of light and combine the fundamental wave properties of amplitude, phase, polarization, wave vector and frequency. [35] Physicist Artem Rudenko from Kansas State University and his colleagues pondered how to improve the images of viruses and microparticles that scientists get from X-rays. [34] A team of materials scientists from Penn State, Cornell and Argonne National Laboratory have, for the first time, visualized the 3-D atomic and electron density structure of the most complex perovskite crystal structure system decoded to date. [33] Hydrogen-powered electronics, travel, and more may be a step closer thanks to the work of a collaborative team of scientists in Japan. [32]

Blockchains promise widescale open Internet applications that are organised decentrally, but this comes at the price of slow performance for every transaction processed by the system. [60] The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more quickly and securely than an electrical network.

A Method of Purchasing Goods and Services on the Internet using Internet Service Providers to Transfer the Money

Authors: Timothy J Walshaw
Comments: 20 Pages.

This article describes a method of purchasing goods and services on the internet using money deposited with an Internet Service Provider (ISP), and a proposed centralized Internet Money Transfer Service (IMTS) to transfer the money from the Buyer's ISP to the Seller's ISP. The method in short requires:- 1.Having the buyer establish an account with the buyer’s internet service provider (ISP); 2.Having the seller establish an account with the sellers’ ISP; 3.The buyer placing funds in the buyer’s ISP, or establishing a line of credit; 4.The buyer purchases a good or service from the seller by sending a message over the internet via the buyer’s ISP and the seller’s ISP; 5.This purchase results in a debiting of the buyer’s account and crediting of the seller’s account; 6.The transfer of money from the buyer’s ISP to the seller’s ISP. 7.For domestic only transfer, there is a single domestic Money Transfer Service, owned by the provider, that transfers money from one domestic ISP to another. 8.The domestic transfer of money from one ISP to another would pass through the domestic Internet Money Transfer Service (IMTS), owned by the provider. All the ISP’s would open accounts with this service, and the Domestic IMTS would refund net payments to each ISP at the end of the day through its banking agent, or require the ISP to refund it the net amount at the end of the day. 9.The domestic IMTS would act as the central banker for this internet money transfer service. There would be an IMTS service in each country. 10.For International money transactions each Domestic IMTS would also act as an International IMTS. 11.The international transfer of money from one ISP to one in another country would pass through the International IMTS, owned by the provider. All the ISP’s would open accounts with this service, and the IMTS would refund net payments to each ISP at the end of the day through its banking agent, or require the ISP to refund it the net amount at the end of the day. 12.Each country’s IMTS would act as the central banker for this internet money transfer service. There would be an IMTS in each country, and they would facilitate inter-country payments. These IMTS’s would facilitate foreign exchange transactions. This methodology could be used in economies where more advanced money transfer systems, based on the use of credit cards and individual credit, are unable to be used. Additionally, there are issues with the safety of the provision of credit card numbers to sellers. The transmission of these numbers over the internet is dangerous, the seller has to be trusted not to misuse the credit card information, and the retention of this information in databases can be highly dangerous. It is a lot safer to transfer the money directly from buyer to seller via third parties using encryption.

Researchers have demonstrated a new technique that can store more optical data in a smaller space than was previously possible on-chip. [57] A new electronic device can developed at the University of Michigan can directly model the behaviors of a synapse, which is a connection between two neurons. [56] "The atom-scale devices we are developing create a new basis for computer electronics that will be able to run at least 100 times faster or operate at the same speed as today but using 100 times less energy," continued Wolkow. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory. [51] A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. [50] Working in the lab of Mikhail Lukin, the George Vasmer Leverett Professor of Physics and co-director of the Quantum Science and Engineering Initiative, Evans is lead author of a study, described in the journal Science, that demonstrates a method for engineering an interaction between two qubits using photons. [49] Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information. [48] Researchers from Intel Corp. and the University of California, Berkeley, are looking beyond current transistor technology and preparing the way for a new type of memory and logic circuit that could someday be in every computer on the planet.

We evaluate the multivalued logic SystemVerilog in IEEE Std 1800-2017. The classical logic proof tables for the connectives And, Or, Xor, and negations are based on the bivalency of 1, 0, X, Z as 0=~1 and Z=~X. This refutes and corrects the standard. We also retrofit and correct IEEE Std 1164-1993 (SynopsysVHDL) for the same.

Authors: George Rajna
Comments: 54 Pages.

A pair of researchers, one with the Langevin Institute, the other a company called Greenerwave, both in France, has developed a way to use ordinary Wi-Fi signals to perform analog, wave-based computations. [34] A scientist involved in expanding quantum communication to a network of users, is continuing his work at the University of Bristol. [33] In recent years, nanofabricated mechanical oscillators have emerged as a promising platform for quantum information applications. [32] Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28] A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24]

Without Waste Heat Supercomputer

Authors: George Rajna
Comments: 85 Pages.

Combining the lossless charge transport of superconductivity with the electronic transport of magnetic information, i.e., spintronics, paves the way for fundamentally novel functionalities for future energy-efficient information technologies. [45] The interactions of quarks and gluons are computed using lattice quantum chromodynamics (QCD)—a computer-friendly version of the mathematical framework that describes these strong-force interactions. [44] The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. [43] In a recent experiment at the University of Nebraska–Lincoln, plasma electrons in the paths of intense laser light pulses were almost instantly accelerated close to the speed of light. [42] Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning—all in a package that's around a thousandth of the size of current accelerators. [41] The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities. [40] The authors designed a mechanism based on the deployment of a transport barrier to confine the particles and prevent them from moving from one region of the accelerator to another. "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said. [38]

Intrusion Detection System and Neutrosophic Theory for MANETs: A Comparative Study

Authors: Haitham ElWahsh, Mona Gamal, A. A. Salama, I.M. El-Henawy
Comments: 7 Pages.

. Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organized in arbitrary and temporary network topologies without communication infrastructure. This network may change quickly and unforeseeable. The unique characteristics of MANET give an adversary the opportunity to launch numerous attacks against ad-hoc networks. So the security is an important role in MANETs. This article aims to present the concept of intrusion detection system (IDs) and surveys some of major intrusion detection approach against neutrosophic intrusion detection system in MANETs. Current IDS’s corresponding to those architectures are also reviewed and compared. This paper introduces the accuracy rate and false alarm rate of four completely different classifiers to observe the percentage and the efficiency of the classifiers in detecting attacks in MANETs. Results show that Neutrosophic intelligent system based on genetic algorithm could facilitate significantly in detecting malicious activities in MANETs. Hence, neutrosophic techniques could be utilized to suit the ambiguity nature of the IDs

A team of scientists from Arizona State University's School of Molecular Sciences and Germany have published in Science Advances online today an explanation of how a particular phase-change memory (PCM) material can work one thousand times faster than current flash computer memory, while being significantly more durable with respect to the number of daily read-writes. [46] A new two-qubit quantum processor that is fully programmable and single electron spins that can be coherently coupled to individual microwave-frequency photons are two of the latest advances in the world of solid-state spin-based quantum computing. [45] Scientists at the National Institute of Standards and Technology (NIST) have now developed a highly efficient converter that enlarges the diameter of a HYPERLINK "https://phys.org/tags/light/" light beam by 400 times. [44] There's little doubt the information technology revolution has improved our lives. But unless we find a new form of electronic technology that uses less energy, computing will become limited by an "energy crunch" within decades. [43] Researchers at the Niels Bohr Institute, University of Copenhagen, have recently succeeded in boosting the storage time of quantum information, using a small glass container filled with room temperature atoms, taking an important step towards a secure quantum encoded distribution network. [42] New work by a team at the University of Bristol's Centre for Quantum Photonics has uncovered fundamental limits on the quantum operations which can be carried out with postselection. [41] The experimental investigation of ultracold quantum matter makes it possible to study quantum mechanical phenomena that are otherwise inaccessible. [40] The molecular switch is the fruit of a collaboration of members from the Departments of Experimental and Theoretical Physics at the University of Würzburg: Dr. Jens Kügel, a postdoc at the Department of Experimental Physics II, devised and ran the experiments.

[36] JILA scientists have invented a new imaging technique that produces rapid, precise measurements of quantum behavior in an atomic clock in the form of near-instant visual art.

[45] Now, an Australian research team has experimentally realised a crucial combination of these capabilities on a silicon chip, bringing the dream of a universal quantum computer closer to reality. [44] A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. [43] As the number of hacks and security breaches rapidly climbs, scientists say there may be a way to make a truly unhackable network by using the laws of quantum physics. [42] This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' light.

[40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers.

Big Data Flow Adjustment Using Knapsack Problem

Authors: Eyman Yosef, A. A. Salama, M. Elsayed Wahed2
Comments: 10 Pages.

The advancements of mobile devices, public networks and the Internet of creature huge amounts of complex data, both construct & unstructured are being captured in trust to allow organizations to produce better business decisions as data is now pivotal for an organizations success. These enormous amounts of data are referred to as Big Data , which enables a competitive advantage over rivals when processed and analyzed appropriately. However Big Data Analytics has a few concerns including Management of Data, Privacy & Security, getting optimal path for transport data, and Data Representation. However, the structure of network does not completely match transportation demand, i.e. , there still exist a few bottlenecks in the network. This paper presents a new approach to get the optimal path of valuable data movement through a given network based on the knapsack problem. This paper will give value for each piece of data, it depends on the importance of this data (each piece of data defined by two arguments size and value), and the approach tries to find the optimal path from source to destination, a mathematical models are developed to adjust data flows between their shortest paths based on the 0 - 1 knapsack problem. We also take out computational experience using the commercial software Gurobi and a greedy algorithm (GA), respectively. The outcome indicates that the suggest models are active and workable. This paper introduced two different algorithms to study the shortest path problems: the first algorithm studies the shortest path problems when stochastic activates and activities does not depend on weights. The second algorithm studies the shortest path problems depends on weights.

Energy-Efficient Data Storage

Authors: George Rajna
Comments: 55 Pages.

Multiferroics are considered miraculous materials for future data storage – as long as their special properties can be preserved at computer operating temperatures. [36] In an international collaboration with IBM Research, the University of Oxford and the International Iberian Nanotechnology Laboratory, QNS scientists used advanced and novel techniques to measure the nuclear spin of individual atoms on surfaces for the first time. [35] A team of scientists led by Professor Richard Layfield at the University of Sussex has published breakthrough research in molecule-based magnetic information storage materials. [34] Just like their biological counterparts, hardware that mimics the neural circuitry of the brain requires building blocks that can adjust how they synapse, with some connections strengthening at the expense of others. [33] Faster and more compact memory storage devices will become a reality when physicists gain precise control of the spins of electrons. [32] UCLA biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. [31] Scientists at the Wellcome Trust/ Cancer Research UK Gurdon Institute, University of Cambridge, have identified a new type of stem cell in the brain which they say has a high potential for repair following brain injury or disease. [30] A team of researchers working at the Weizmann Institute of Science has found that organoids can be used to better understand how the human brain wrinkles as it develops. [29] A team of biologists has found an unexpected source for the brain's development, a finding that offers new insights into the building of the nervous system. [28] Researchers discover both the structure of specific brain areas and memory are linked to genetic activity that also play important roles in immune system function. [27] The inner workings of the human brain have always been a subject of great interest. Unfortunately, it is fairly difficult to view brain structures or intricate tissues due to the fact that the skull is not transparent by design. [26] But now there is a technology that enables us to "read the mind" with growing accuracy: functional magnetic resonance imaging (fMRI). [25]

University of Groningen (UG) physicists are working on memristors made from niobium-doped strontium titanate, which mimic the function of neurons. [23] IBM researchers are developing a new computer architecture, better equipped to handle increased data loads from artificial intelligence. [22] A computer built to mimic the brain's neural networks produces similar results to that of the best brain-simulation supercomputer software currently used for neural-signaling research, finds a new study published in the open-access journal Frontiers in Neuroscience. [21] The possibility of cognitive nuclear-spin processing came to Fisher in part through studies performed in the 1980s that reported a remarkable lithium isotope dependence on the behavior of mother rats. [20] And as will be presented today at the 25th annual meeting of the Cognitive Neuroscience Society (CNS), cognitive neuroscientists increasingly are using those emerging artificial networks to enhance their understanding of one of the most elusive intelligence systems, the human brain. [19] U.S. Army Research Laboratory scientists have discovered a way to leverage emerging brain-like computer architectures for an age-old number-theoretic problem known as integer factorization. [18] have come up with a novel machine learning method that enables scientists to derive insights from systems of previously intractable complexity in record time. [17] Quantum computers can be made to utilize effects such as quantum coherence and entanglement to accelerate machine learning. [16] Neural networks learn how to carry out certain tasks by analyzing large amounts of data displayed to them. [15] Who is the better experimentalist, a human or a robot? When it comes to exploring synthetic and crystallization conditions for inorganic gigantic molecules, actively learning machines are clearly ahead, as demonstrated by British Scientists in an experiment with polyoxometalates published in the journal Angewandte Chemie.

A Quality-aware View of Accessibility for Voice-based Interfaces

Authors: Zhixuan Zhou, Tianwei Chen
Comments: 4 Pages. extended abstract

Voice interfaces are giving people who have difficulty using graphic-based systems more access to information and services on the Internet. However, there hasn’t been a widely-acknowledged definition of accessibility in this research field. While progress in voice-interface technologies do improve people’s user experience, privacy issues arise and contradict with the nature of accessibility in many cases. In our extended abstract, we try to propose a definition of accessibility from a quality-aware perspective. Accessibility (as generally defined), usability, personalization, confidence and privacy are adopted as five metrics for evaluating quality-aware accessibility. Privacy issues are given special attention when we pursue better accessibility. Real-world experimental platforms can be built under this guidance later on.

Revise on the State of the Art on Security Policies and Mechanisms Applicable to Vehicular Delay Torlant Network Context of Cooperation

Authors: Zeeshan Haider
Comments: 7 Pages.

This article revision the literature related to Vehicular Delay Tolerant Network with focus on Cooperation. It starts by examining definitions of some of the fields of research in VDTN on security policies. An overview of VDTN on security policies cooperative networks is presented. A security policy is a high-level specification of the security properties that a given system should possess. It is a means for designers domain experts and implementers to communicate with each other, and a blueprint that drives a project from design through implementation and validation. We offer a survey of the most significant security policy models in the literature showing security may mean very different things in different contexts and we review some of the mechanisms used to implement a gievn security policy.

Defects Promise Quantum Communication

Authors: George Rajna
Comments: 33 Pages.

These qubits are based on silicon carbide in which molybdenum impurities create color centers. [23] Scientists at Radboud University discovered a new mechanism for magnetic storage of information in the smallest unit of matter: a single atom. [22] One of these are single-atom magnets: storage devices consisting of individual atoms stuck ("adsorbed") on a surface, each atom able to store a single bit of data that can be written and read using quantum mechanics. [21] Physicists have experimentally demonstrated 18-qubit entanglement, which is the largest entangled state achieved so far with individual control of each qubit. [20] University of Adelaide-led research has moved the world one step closer to reliable, high-performance quantum computing. [19] A team of researchers with members from IBM Research-Zurich and RWTH Aachen University has announced the development of a new PCM (phase change memory) design that offers miniaturized memory cell volume down to three nanometers. [18] Monatomic glassy antimony might be used as a new type of single-element phase change memory. [17] Physicists have designed a 3-D quantum memory that addresses the tradeoff between achieving long storage times and fast readout times, while at the same time maintaining a compact form. [16] Quantum memories are devices that can store quantum information for a later time, which are usually implemented by storing and re-emitting photons with certain quantum states. [15] The researchers engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip. [14] Intel has announced the design and fabrication of a 49-qubit superconducting quantum-processor chip at the Consumer Electronics Show in Las Vegas.

The findings, which have been published in Science Advances, open up new ways to create and manipulate complex magnetic structures and use these structures for green IT applications. [32] Unique physical properties of these "magic knots" might help to satisfy demand for IT power and storage using a fraction of the energy. [31] A skyrmion is the magnetic version of a tornado which is obtained by replacing the air parcels that make up the tornado by magnetic spins, and by scaling the system down to the nanometre scale. [30] A new material created by Oregon State University researchers is a key step toward the next generation of supercomputers. [29] Magnetic materials that form helical structures—coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule—occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors—sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields. [27] At Carnegie Mellon University, Materials Science and Engineering Professor Mike McHenry and his research group are developing metal amorphous nanocomposite materials (MANC), or magnetic materials whose nanocrystals have been grown out of an amorphous matrix to create a two phase magnetic material that exploits both the attractive magnetic inductions of the nanocrystals and the large electrical resistance of a metallic glass. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24]

If the computer or system being attacked has a security system, such as a firewall or anti-virus software, it might be able to recognize some code as being bad and prevent itself from being infected. [37] Qrypt, Inc., has exclusively licensed a novel cyber security technology from the Department of Energy's Oak Ridge National Laboratory, promising a stronger defense against cyberattacks including those posed by quantum computing. [36] Researchers have shown that a chip-based device measuring a millimeter square could be used to generate quantum-based random numbers at gigabit per second speeds. [35] The researchers have focussed on a complex quantum property known as entanglement, which is a vital ingredient in the quest to protect sensitive data. [34] Cryptography is a science of data encryption providing its confidentiality and integrity. [33] Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure.

Security Gaps in IPsec

Authors: George Rajna
Comments: 58 Pages.

In collaboration with colleagues from Opole University in Poland, researchers at Horst Görtz Institute for IT Security (HGI) at Ruhr-Universität Bochum (RUB) have demonstrated that the internet protocol IPsec is vulnerable to attacks. [35] As cloud storage becomes more common, data security is an increasing concern. [34] Scientists of the National Research Nuclear University MEPhI (Russia) have proposed a scheme for optical encoding of information based on the formation of wave fronts, and which works with spatially incoherent illumination. [33] A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). [32] In the race to build a computer that mimics the massive computational power of the human brain, researchers are increasingly turning to memristors, which can vary their electrical resistance based on the memory of past activity. [31] Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into two-dimensional atomic sheets for memory storage has failed to uncover their potential— until now. [30] Scientists used spiraling X-rays at the Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns – dubbed polar vortices – in a synthetically layered material. [28] To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. [27] Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator.

Magnetic Antiparticles for Information Technologies

Authors: George Rajna
Comments: 45 Pages.

Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems—donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.

Authors: Juan Ramón González Álvarez
Comments: 7 Pages.

After showing that only one of the different versions of Pollack's rule found on the literature agrees with the experimental behavior of a CPU running at stock frequency versus the same CPU overclocked, we introduce a formal simplified model of a CPU and derive a generalized Pollack's rule also valid for multithread architectures, caches, clusters of processors, and other computational devices described by this model. A companion equation for power consumption is also proposed.

A Fast Algorithm for the Demosaicing Problem Concerning the Bayer Pattern

Authors: Antonio Boccuto, Ivan Gerace, Valentina Giorgetti, Matteo Rinaldi
Comments: 18 Pages.

In this paper we deal with the demosaicing problem when the Bayer pattern is used. We propose a fast heuristic algorithm, consisting of three parts. In the first one, we initialize the green channel by means of an edge-directed and weighted average technique. In the second part, the red and blue channels are updated, thanks to an equality constraint on the second derivatives. The third part consists of a constant-hue-based interpolation. We show experimentally how the proposed algorithm gives in mean better reconstructions than more computationally expensive algorithms.

Skyrmions Revolutionise Computing

Authors: George Rajna
Comments: 52 Pages.

Unique physical properties of these "magic knots" might help to satisfy demand for IT power and storage using a fraction of the energy. [31] A skyrmion is the magnetic version of a tornado which is obtained by replacing the air parcels that make up the tornado by magnetic spins, and by scaling the system down to the nanometre scale. [30] A new material created by Oregon State University researchers is a key step toward the next generation of supercomputers. [29] Magnetic materials that form helical structures—coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule—occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors—sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields. [27] At Carnegie Mellon University, Materials Science and Engineering Professor Mike McHenry and his research group are developing metal amorphous nanocomposite materials (MANC), or magnetic materials whose nanocrystals have been grown out of an amorphous matrix to create a two phase magnetic material that exploits both the attractive magnetic inductions of the nanocrystals and the large electrical resistance of a metallic glass. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24] Topological effects, such as those found in crystals whose surfaces conduct electricity while their bulk does not, have been an exciting topic of physics research in recent years and were the subject of the 2016 Nobel Prize in physics.

Quantum Entangled Internet

Authors: George Rajna
Comments: 48 Pages.

Researchers at QuTech in Delft have succeeded in generating quantum entanglement between two quantum chips faster than the entanglement is lost. [28] Scientists at the Department of Energy's Oak Ridge National Laboratory are conducting fundamental physics research that will lead to more control over mercurial quantum systems and materials. [27] Physicists in Italy have designed a " quantum battery " that they say could be built using today's solid-state technology. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22] The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18]

Researchers at the Czech Academy of Sciences, together with their colleagues at Mainz University, have discovered a way to dramatically increase data processing rates by around 100 times up to terahertz speeds. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution.

[17] Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations. [16]

Spin Wave Integrated Circuits

Comments: 56 Pages.

Taichi Goto at the Toyohashi University of Technology and others collaborated to create a single-crystalline yttrium iron garnet (YIG) film as a magnetic insulator on multiple substrates, and transmit the spin waves. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29] Magnetic materials that form helical structures—coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule—occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices.

Minimum Amount of Text Overlapping in Document Separation

Authors: Antonio Boccuto, Ivan Gerace, Valentina Giorgetti
Comments: 79 Pages.

We consider a Blind Source Separation problem. In particular we focus on reconstruction of digital documents degraded by bleed-through and show-through effects. In this case, since the mixing matrix, the source and data images are nonnegative, the solution is given by a Nonnegative Factorization. As the problem is ill-posed, further assumptions are necessary to estimate the solution. In this paper we propose an iterative algorithm in order to estimate the correct overlapping level from the verso to the recto of the involved document. Thus, the proposed method is a Correlated Component Analysis technique. This method has low computational costs and is fully unsupervised. Moreover, we give an extension of the proposed algorithm in order to deal with a not translation invariant model. Our experimental results confirm the goodness of the method.

University of Waterloo chemists have found a much faster and more efficient way to store and process information by expanding the limitations of how the flow of electricity can be used and managed. [31] A University of Washington-led team has now taken this one step further by encoding information using magnets that are just a few layers of atoms in thickness. [30] Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity. [29] Researchers have discovered that using an easily made combination of materials might be the way to offer a more stable environment for smaller and safer data storage, ultimately leading to miniature computers.

[27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film.

Bitcoin With Heterogenic Block Sizes: A Scaling Proposal

Authors: Santi J. Vives
Comments: 10 Pages.

We propose a bitcoin generalization as a solution to the problem of scalability. The block is redefined as a sequence of sub-blocks of increasing sizes that coexist as different levels of compromise between decentralization and transactions throughput. Miners and users can decide individually the size they use without affecting others.

Researchers at Duke University and North Carolina State University have demonstrated the first custom semiconductor microparticles that can be steered into various configurations repeatedly while suspended in water. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark. [21] In the September 23th issue of the Physical Review Letters, Prof. Julien Laurat and his team at Pierre and Marie Curie University in Paris (Laboratoire Kastler Brossel-LKB) report that they have realized an efficient mirror consisting of only 2000 atoms. [20] Physicists at MIT have now cooled a gas of potassium atoms to several nanokelvins—just a hair above absolute zero—and trapped the atoms within a two-dimensional sheet of an optical lattice created by crisscrossing lasers. Using a high-resolution microscope, the researchers took images of the cooled atoms residing in the lattice. [19] Researchers have created quantum states of light whose noise level has been " squeezed " to a record low. [18] An elliptical light beam in a nonlinear optical medium pumped by " twisted light " can rotate like an electron around a magnetic field. [17] Physicists from Trinity College Dublin's School of Physics and the CRANN Institute, Trinity College, have discovered a new form of light, which will impact our understanding of the fundamental nature of light.

Magnetic Data Storage of the Future

Authors: George Rajna

Single-molecule magnets (SMMs) have been attracting a lot of attention recently. This is because of the increased demand for faster, longer-lasting and lower-energy IT systems, and the need for higher data storage capacity.

Authors: Vikas Ramachandra, Aimei Huang, Truong Q. Nguyen
Comments: 21 Pages.

We explore a new technique for video frame rate up-conversion. A noniterative multilayer motion estimation algorithm is investigated, based on spatio-temporal smoothness constraints. For regions in the interpolated frame which cannot be motion compensated, we use an exemplar based video inpainting algorithm. The proposed approach yields excellent results compared to other previous approaches

OFDM Performance Improvement Based on Active Constellation Extension and Active Interference Cancelation

Authors: SongIl Choe, IlNam Ri, SongChol Dong, IlSok Kim, ChunHo Pak
Comments: 9 Pages.

Orthogonal Frequency Division Multiplexing (OFDM) is a transceiver technology able to achieve spectrally efficient and high data rate wireless transmissions. It is also able to transmit in a non-contiguous (NC) fashion by utilizing several separate spectral whitespaces. Cognitive radio systems based on non-contiguous orthogonal frequency division multiplexing (NC-OFDM) is a promising technique that can provide efcient bandwidth utilization for high data rate wireless communication systems under frequency selective fading environments. However, the high peak to average power ratio (PAPR) and large spectrum sidelobe power are the two major limitations at the transmitter side of the NC-OFDM based Cognitive Radio (CR) system, which may significantly reduce the power efficiency and performance of the system. In this paper, we present a joint method for the PAPR reduction and sidelobe suppression based on Active Constellation Extension(ACE) and Active Interference Cancelation(AIC). The key idea of the proposed method is to dynamically extend part of the constellation points on the secondary user (SU) subcarriers based on ACE and add several SC symbols on the primary user (PU) subcarriers based on AIC to generate the appropriate cancelation signal for joint PAPR reduction and sidelobe suppression. Since the convex optimization is computationally complex in nature, a suboptimal method is also proposed whose simulation result shows that there is a significant improvement in terms of PAPR and sidelobe reduction.

Acceleration of FSK Caller id Demodulation Using Sos Filter Structure

Authors: WonJun Min, YuSong Kim, Dokkil Kang
Comments: 5 Pages.

Abstract - In several systems such as VoIP analog gateway it is key feature to demodulate FSK caller ID signal on voice band. FSK caller ID are widely used as it has a lot of advantages[1] and to demodulate it correctly and speedily is important for stability of system operation as long as subscriber number increases. In prior paper this subject has been researched, but sampling frequency is selected by special values that differ from typical values [2]. In other paper the system is constructed using the filter of floating coefficients (method 1) or using the filter of integer coefficients that is obtained by rounding the product of floating coefficients of long significant digit and special integer value and process additional operation to avoid over value state(method 2), so floating operations consume time[3]. The common communication systems use typical frequency such as 8 kHz and if FSK caller ID detection processing is running on embedded processors that support only fixed point operation then floating operation will consume hardly system resources. This paper introduces the SOS structure of filter to realization of FSK caller ID demodulation, so not only ensures accuracy but also accelerates processing.

In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. [33] With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. [32] A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface. [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28] A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24]

On Point Processes in Multitarget Tracking

Authors: Ronald Mahler
Comments: 18 Pages.

The finite-set statistics (FISST) approach to multitarget tracking---random finite sets (RFS's), belief-mass functions, and set derivatives---was introduced in the mid-1990s. Its current extended form---probability generating functionals (p.g.fl.'s) and functional derivatives---dates from 2001. In 2008, an "elementary" alternative to FISST was proposed, based on "finite point processes" rather than RFS's. This was accompanied by single-sensor and multisensor versions of a claimed generalization of the PHD filter, the "multitarget intensity filter" or "iFilter." Then in 2013 in the Journal of Advances in Information Fusion (JAIF) and elsewhere, the same author went on to claim that the FISST p.g.fl./functional derivative approach is actually "due to" (a "corollary" of) a 50-year-old pure-mathematics paper by Moyal; and described a "point process" p.g.fl./functional derivative approach to multitarget tracking supposedly based on it. In this paper it is shown that: (1) non-RFS point processes are a phenomenologically erroneous foundation for multitarget tracking; (2) nearly every equation, concept, discussion, derivation, and methodology in the JAIF paper originally appeared in FISST publications, without being so attributed; (3) FISST cannot possibly be "due to Moyal"; and (4) the "point process" approach described in JAIF differs from FISST only in regard to terminology and notation, and thus in this sense appears to be an obscured, phenomenologically erroneous, and improperly attributed copy of FISST. The paper concludes with the following question: Given the above, do the peer-review standards of the Journal of Advances in Information Fusion rise to the level expected of any credible scientific journal? It is also shown that the derivations of the single-sensor and multisensor iFilter appear to have had major errors, as did a subsequent recasting of the multisensor iFilter as a "traffic mapping filter."

Microstrip Quad-Channel Diplexer Using Quad-Mode Square Ring Resonators

Authors: Jinli Zhang, Doudou Pang, Wei Wang, Haihua Chen, Ming He, Lu Ji, Xu Zhang, Xinjie
Comments: 4 Pages.

A new compact microstrip quad-channel diplexer (2.15/3.60 GHz and 2.72/5.05 GHz) using quad-mode square ring resonators is proposed. The quad-channel diplexer is composed of two quad-mode square ring resonators (QMSRR) with one common input and two output coupled-line structures. By adjusting the impedance ratio and length of the QMSRR, the resonant modes can be easily controlled to implement a dual-band bandpass filter. The diplexer show a small circuit size since it’s constructed by only two QMSRRs and common input coupledline structure while keeping good isolations (> 28 db). Good agreements are achieved between measurement and simulation.

Interference Mitigation Techniques in Modern Wireless Communication Systems

Authors: Alexandros-Apostolos A. Boulogeorgos
Comments: 231 Pages. PhD Thesis

During the last decades, wireless communications have evolved from a scarce technology, used by professionals for niche applications to a rapidly advancing research field. Ever increasing proliferation of smart devices, the introduction of new emerging multimedia applications, together with an exponential rise in wireless data (multimedia) demand and usage are already creating a significant burden on existing wireless systems. Future wireless networks, with improved data rates, capacity, latency, and quality of service (QoS) requirements, are expected to be the panacea of most of the current wireless systems’ problems. Interference management is critical towards this goal, whereas transceiver design and implementation are expected to play an important role. This thesis investigates the influence of interference in wireless systems, revisits promising network- and user-side interference management solutions, as well as studies the impact of interference, caused by hardware imperfections, on the performance of the wireless link and propose countermeasures. The thesis is divided into two parts. In the first part of the thesis, different types of interference and modern interference management solutions, which are expected to be used in the future wireless networks, are reviewed. Moreover, the influence of fading and interference, due to the existence of multiple possible users operating simultaneously in the same carrier frequency, on the spectrum sensing capability of a low-complexity energy detector (ED) is investigated. Analytical tools for the performance evaluation of this problem, i.e., the false alarm and detection probabilities, are derived, while the problem of appropriately selecting the energy detection threshold and the spectrum sensing duration, in order to satisfy a specific requirement, is discussed. The results reveal the detrimental effect of interference and the importance of taking into consideration the wireless environment when evaluating the ED spectrum sensing performance and selecting the ED threshold. Finally, the offered analytical framework can be applied in cognitive radio systems, which are included in several wireless standards, and are expected to be employed in ultra-dense wireless environments. The second part of this thesis investigates the impact of transceivers radio frequency (RF) front-end imperfections on the performance of the wireless system. RF imperfections generally result to signal distortion in single-carrier communications, while, in multi-carrier communications, they additionally cause interference. In both cases, RF imperfections may cause significant degradation to the quality of the wireless link, which becomes more severe as the data rates increases. Motivated by this, after briefly illustrating the influence of different types of RF imperfections, namely in-phase and quadrature imbalance (IQI), phase noise, and amplifiers non-linearities, the analytical framework for the evaluation and quantification of the effect of IQI on wireless communications in the context of cascaded fading channels, is derived. To this end, closed-form expressions for the outage probability over N∗Nakagami-m channels for both the cases of single- and multi-carrier communications, when at least one communication node suffers from IQI, are provided. To justify the importance and practical usefulness of the analysis, the offered expressions along with several deduced corresponding special cases are employed in the context of vehicle-to-vehicle communications. This study gives critical insight for the performance degradation in wireless communications, due to RF imperfections, and indicates the need for designing proper RF imperfections compensation techniques. Next, the impact of IQI and partial successive interference suppression (SIS) in the spectrum sensing of full duplex CR systems, for both the cases of single- and multi-carrier ED, is studied. In this context, closed-form expressions are derived for the false alarm and detection probabilities, in the general case, where partial SIS and joint transmitter and receiver IQI are considered. The derived expressions can be used in order to properly select the energy detection threshold that maximizes the ED spectrum sensing capabilities. Additionally, the joint influence of fading and several RF impairments on energy detection based spectrum sensing for CR systems in multi-channel environments is investigated. After assuming flat-fading Rayleigh channels and complex Gaussian transmitted signals, as well as proving that, for a given channel realization, the joint effect of RF impairments can be modeled as a complex Gaussian process, closed-form expressions for the probabilities of false alarm and detection are derived. Based on these expressions, the impact of RF impairments and fading on the spectrum sensing capability of the ED is studied. The results illustrated the degrading influence of RF imperfections on the ED spectrum sensing performance, which bring significant losses in the utilization of the spectrum. Furthermore, the impact of uncompensated IQI on orthogonal frequency division multiple access (OFDMA) systems, in which a power allocation (PA) policy is employed in order to maximize each user’s capacity, is demonstrated. To overcome, the user’s capacity loss, due to IQI, a novel, low-complexity PA strategy is presented, which, by taking into account the levels of IQI of the served users, notably enhance each user’s achievable capacity. Finally, a novel low-complexity scheme, which improves the performance of single-antenna multi-carrier communication systems, suffering from IQI at the receiver, is proposed. The proposed scheme, which we refer to as I/Q imbalance self-interference coordination (IQSC), not only mitigate the detrimental effect of IQI, but, through appropriate signal processing, also coordinates the self-interference terms produced by IQI, in order to achieve second-order frequency diversity. In order to evaluate the performance of IQSC, closed-form expressions for the resulting outage probability and symbol error rate are derived. The findings reveal that IQSC is a promising low-complexity technique for significantly increasing the reliability of low-cost devices that suffer from high levels of IQI.

Computer Memory Magnetic Revolution

Authors: George Rajna
Comments: 36 Pages.

When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22] The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18] Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. [17] Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations. [16] Physicists have proposed a new type of Maxwell's demon—the hypothetical agent that extracts work from a system by decreasing the system's entropy—in which the demon can extract work just by making a measurement, by taking advantage of quantum fluctuations and quantum superposition. [15] Pioneering research offers a fascinating view into the inner workings of the mind of 'Maxwell's Demon', a famous thought experiment in physics. [14]

IBM Optical Receiver

Comments: 58 Pages.

Based on complementary metal-oxide-semiconductor (COMS) technology—a standard low-cost, high-volume chip manufacturing technique used for most processors and chips today—a group of researchers from IBM Research in Zurich, Switzerland, together with a consortium working under the EU-funded project "ADDAPT," have demonstrated a novel optical receiver (RX) that can achieve an aggregate bandwidth of 160 Gb/s through four optical fibers. [36] An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach developed at the University of Freiburg.

A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24] Topological effects, such as those found in crystals whose surfaces conduct electricity while their bulk does not, have been an exciting topic of physics research in recent years and were the subject of the 2016 Nobel Prize in physics. [23] A new technique developed by MIT researchers reveals the inner details of photonic crystals, synthetic materials whose exotic optical properties are the subject of widespread research. [22] In experiments at SLAC, intense laser light (red) shining through a magnesium oxide crystal excited the outermost " valence " electrons of oxygen atoms deep inside it. [21] LCLS works like an extraordinary strobe light: Its ultrabright X-rays take snapshots of materials with atomic resolution and capture motions as fast as a few femtoseconds, or millionths of a billionth of a second. For comparison, one femtosecond is to a second what seven minutes is to the age of the universe. [20] A 'nonlinear' effect that seemingly turns materials transparent is seen for the first time in X-rays at SLAC's LCLS. [19] Leiden physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been accomplished with actual atoms. It is an important step toward light-based quantum technology. [18]

Energy-Efficient Two-Way Relaying with Multiple Antennas

Authors: Thanaphat Srivantana, Kiattisak Maichalernnukul
Comments: 4 Pages.

In this paper, we propose various kinds of energy-efficient two-way multi-antenna relaying with simultaneous wireless information and power transfer (SWIPT) and investigate their performance. Specifically, we first consider a two-way relay network where a pair of single-antenna end nodes communicate with each other through a multi-antenna relay node that is energy constrained. This relay node harvests energy from the two end nodes and use the harvested energy for forwarding their information. Three relaying schemes which support the considered network then build on the power splitting-based relaying protocol. The average bit error rates of these schemes are evaluated and compared by computer simulations considering several network parameters, including the number of relay antennas and the power splitting ratio. Such evaluation and comparison provide useful insights into the performance of SWIPT-based two-way multi-antenna relaying.

Comments: 8 Pages.

This paper deals with the merger of the two lightweight stream ciphers – A5/1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks of the individual algorithms. The bits generated by the Trivium cipher (output) will act as the input of the A5/1 cipher. The registers used in the A5/1 cipher will be filled by the output bits of the Trivium cipher. The three registers will then be connected to generate an output which will be our required key stream. we are using Trivium and A5/1 algorithm and making changes to suit our needs.

This article is continuation to my previous article on the acoustic evidence of the assassination of President John. F. Kennedy. Four putative gunshots are identified from Dictabelt data, they are matched to the Zapruder film, and a fifth shot is postulated because of the Zapruder film. Finally echo correlation analysis is performed. It is only suggestive because data is too noisy, but agrees with what can be expected by other arguments.

Smart Irrigation :Iot Based Irrigation Monitoring System

Authors: Shaif Chowdhury, Soummyo Priyo Chattopadhyay, Avijit Ghose
Comments: 6 Pages.

The project aims at autonomous monitoring of irrigation system in both large and small scale plantation estates with a view to eradicating the manual system which involves personal liability concerns and the ignorance of the field workers. Even sometimes the experienced people cannot assure how much fertilizers or water must be used for the maximum yield. Hence our system will monitor the temperature, humidity, moisture content of the soil and other physical factors like presence of major pollutants in air like PM2.5, PM10, CO,NOx etc. The factors and the crop yield are compared with dataset of past surveys and will try to predict is irrigation is necessary or not. With the help of this information, the rate of releasing water from pumps is decided and fed to a microcontroller system which supervises and controls the whole irrigation system. Besides, there is also provision to monitor plant growth both in longitudinally and horizontally.

In the year 2001 Donald B. Thomas published in the journal Science&Justice an article where the acoustic evidence in the J. F. Kennedy assassination case was re-evaluated. Two later articles rebutted the claims of Thomas. In this article it is shown that while the synchronization points used by Thomas are not confirmed by the present study, the main conclusion of Thomas is correct: the earlier synchronization was invalid. The article shows that signals that were claimed to be crosstalk have apparently been manipulated by signal processing methods.

New Sufficient Conditions of Signal Recovery with Tight Frames Via $l_1$-Analysis

Authors: Jianwen Huang, Jianjun Wang
Comments: 15 Pages.

The paper discusses the recovery of signals in the case that signals are nearly sparse with respect to a tight frame $D$ by means of the $l_1$-analysis approach. We establish several new sufficient conditions regarding the $D$-restricted isometry property to ensure stable reconstruction of signals that are approximately sparse with respect to $D$. It is shown that if the measurement matrix $\Phi$ fulfils the condition $\delta_{ts}<t/(4-t)$ for $0<t<4/3$, then signals which are approximately sparse with respect to $D$ can be stably recovered by the $l_1$-analysis method. In the case of $D=I$, the bound is sharp, see Cai and Zhang's work \cite{Cai and Zhang 2014}. When $t=1$, the present bound improves the condition $\delta_s<0.307$ from Lin et al.'s reuslt to $\delta_s<0.333$.

Gnuplantex: a Novel Free Software for Analyzing Texture and Color in Plants; Its Industrial Application.

Authors: Enrique Marcet Garcia
Comments: 22 Pages.

In many industrial applications where plants are used as raw material in the production process, is important to perform a proper phytosanitary and quality control. To perform these controls is possible by raw materials visual inspection, however, to analyze texture and color in plants would allow identifying/quantifying problems as: nutrient deficiencies; diseases (caused by fungi, bacteria, etc.), as well as to identify problems in industrial process. The aims of this paper are: (1) to develop free software (GPL) for texture analysis (GLCM), color measurement (CIELab) and color-difference calculation using CIEDE2000; (2) software application in the analysis of Moringa oleifera Lam leaves. For programming the software we used Perl and wxBasic languages. GNUplantex is easy-to-use software. It is available at: http://www.2shared.com/file/tvzJPBy5/gnuplantex.html

Time-Coordinated Signatures

Authors: Santi J. Vives Maccallini
Comments: 17 Pages.

Abstract: Hash-based signatures are typically stateful: they need to keep a state with the number of past signatures to know which values have been already used and cannot be reused. If the memory storing the state fails, the security would degrade. Some implementations solve the problem by using a number of secret values so large that the probability of picking the same at random is negligible, but this solution can make the signatures impractical for some real world applications. This paper proposes a new approach to hash-based signatures: we show that it is possible to derive their state entirely from time, without the need to keep a state with the number of past signatures, Keywords: many-times signatures, hash-based signatures, post-quantum cryptography, stateless, authentication, merkle tree, directed graph, time, clock.

Formalizing Image Processing in Higher Order Logic(hol) by Understanding and Using XML-Hol-Scala-JVM Software Framework Towards Processing of Cryo-Em/tem/sem Images Based on Levy Processes a Novel Suggestion

Authors: D.N.T.Kumar
Comments: 14 Pages. A NOVEL SUGGESTION IN THE CONTEXT OF INSTRUMENTATION & HIGH PERFORMANCE COMPUTING ENVIRONMENT.

In this research work it was proposed to understand and use Levy processes based on XML-HOL-Scala/JVM software in the context of Cryo-EM/SEM/TEM image processing.Though the discussion is very much related to Cryo-EM based topics similar logic could be applied in developing a convenient informatics framework to process other electron-microscopy images.It is one of the pioneering efforts in this direction to use Levy processes in such situations.In the near future,inorder to achieve “Smart & Intelligent” image processing platforms,we could envision incorporating advanced technology based on HOL-XML-Scala/JVM framework which will allow the seamless integration of technologies such as agents, model-based reasoning,genetic algorithms,and artificial neural nets towards robust image processing tasks on-hand.

Detection and Prevention of Non-PC Botnets

Authors: Jai Puneet Singh, Akashdeep Chauhan
Comments: 7 Pages.

Botnet attacks are serious and well-established threat to the internet community. These attacks are not only restricted to PC or laptops but spreading their roots to a device such as smartphones, refrigerators, and medical instruments. According to users, they are devices which are least prone to attacks. On the other hand, a device that is expected to be least vulnerable has low-security aspects which attract the attackers. In this paper, we have listed the details of latest Botnet attacks and common vulnerabilities behind such attacks. We have also explained as well as suggested proved Detection ways based on their types. After an analysis of attacks and detection techniques, we have suggested recommendations which can be utilized in order to mitigate such attacks.

Magnetic Data Writing

Authors: George Rajna
Comments: 33 Pages.

Magnetic data storage has long been considered too slow for use in the working memories of computers. Researchers at ETH have now investigated a technique by which magnetic data writing can be done considerably faster and using less energy. [20] A team of researchers from the U.S. and Italy has built a quantum memory device that is approximately 1000 times smaller than similar devices— small enough to install on a chip. [19] The cutting edge of data storage research is working at the level of individual atoms and molecules, representing the ultimate limit of technological miniaturisation. [18] This is an important clue for our theoretical understanding of optically controlled magnetic data storage media. [17] A crystalline material that changes shape in response to light could form the heart of novel light-activated devices. [16] Now a team of Penn State electrical engineers have a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a near zero thickness and weight. [15] Just like in normal road traffic, crossings are indispensable in optical signal processing. In order to avoid collisions, a clear traffic rule is required. A new method has now been developed at TU Wien to provide such a rule for light signals. [14] Researchers have developed a way to use commercial inkjet printers and readily available ink to print hidden images that are only visible when illuminated with appropriately polarized waves in the terahertz region of the electromagnetic spectrum. [13] That is, until now, thanks to the new solution devised at TU Wien: for the first time ever, permanent magnets can be produced using a 3D printer. This allows magnets to be produced in complex forms and precisely customised magnetic fields, required, for example, in magnetic sensors. [12]

Minimum Amount of Text Overlapping in Document Separation

Authors: Antonio Boccuto, Ivan Gerace, Valentina Giorgetti
Comments: 91 Pages.

We consider a Blind Source Separation problem. In particular we focus on reconstruction of digital documents degraded by bleed-through and show-through effects. In this case, since the mixing matrix, the source and data images are nonnegative, the solution is given by a Nonnegative Factorization. As the problem is ill-posed, further assumptions are necessary to estimate the solution. In this paper we propose an iterative algorithm in order to estimate the correct overlapping level from the verso to the recto of the involved document. Thus, the proposed method is a Correlated Component Analysis technique. This method has low computational costs and is fully unsupervised. Moreover, we give an extension of the proposed algorithm in order to deal with a not translation invariant model. Our experimental results confirm the goodness of the method.

How Many Shots Were Fired on 22. November 1963 in Dealey Plaza?

Authors: Jorma Jormakka
Comments: 14 Pages. Figures 17 and 19 had changed places, now corrected.

This article is continuation to my previous article on the acoustic evidence of the assassination of President John. F. Kennedy. Four putative gunshots are identified from Dictabelt data, they are matched to the Zapruder film, and a fifth shot is postulated because of the Zapruder film. Finally echo correlation analysis is performed. It is only suggestive because data is too noisy, but agrees with what can be expected by other arguments.

Was the J. F. Kennedy Assassination a Conspiracy?

Authors: Jorma Jormakka
Comments: 10 Pages. Typos corrected.

In the year 2001 Donald B. Thomas published in the journal Science&Justice an article where the acoustic evidence in the J. F. Kennedy assassination case was re-evaluated. Two later articles rebutted the claims of Thomas. In this article it is shown that while the synchronization points used by Thomas are not confirmed by the present study, the main conclusion of Thomas is correct: the earlier synchronization was invalid. The article shows that signals that were claimed to be crosstalk have apparently been manipulated by signal processing methods.

Perturbations of Compressed Data Separation with Redundant Tight Frames

Authors: Feng Zhang, Jianjun Wang, Yao Wang, Jianwen Huang
Comments: 12 Pages.

In the era of big data, the multi-modal data can be seen everywhere. Research on such data has attracted extensive attention in the past few years. In this paper, we investigate perturbations of compressed data separation with redundant tight frames via ˜Φ-ℓq-minimization. By exploiting the properties of the redundant tight frame and the perturbation matrix, i.e., mutual coherence, null space property and restricted isometry property, the condition on reconstruction of sparse signal with redundant tight frames is established and the error estimation between the local optimal solution and the original signal is also provided. Numerical experiments are carried out to show that ˜Φ-ℓq-minimization are robust and stable for the reconstruction of sparse signal with redundant tight frames. To our knowledge, our works may be the first study concerning perturbations of the measurement matrix and the redundant tight frame for compressed data separation.

A Sharp Sufficient Condition of Block Signal Recovery Via $l_2/l_1$-Minimization

Authors: Jianwen Huang, Jianjun Wang, Wendong Wang
Comments: 16 Pages.

This work gains a sharp sufficient condition on the block restricted isometry property for the recovery of sparse signal. Under the certain assumption, the signal with block structure can be stably recovered in the present of noisy case and the block sparse signal can be exactly reconstructed in the noise-free case. Besides, an example is proposed to exhibit the condition is sharp. As byproduct, when $t=1$, the result enhances the bound of block restricted isometry constant $\delta_{s|\mathcal{I}}$ in Lin and Li (Acta Math. Sin. Engl. Ser. 29(7): 1401-1412, 2013).
