Generalization of Pollack Rule and Alternative Power Equation

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.

Spin Control Information Processing

Authors: George Rajna
Comments: 44 Pages.

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. [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.

Optical Skyrmions

Authors: George Rajna
Comments: 53 Pages.

Technion-Israel institute of Technology researchers have succeeded in generating minute "nano-hedgehogs of light" called optical skyrmions, which could make possible revolutionary advances in information processing, transfer and storage. [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]

Future Rewritable Memory

Authors: George Rajna
Comments: 32 Pages.

Scientists at the University of Alberta in Edmonton, Canada have created the most dense, solid-state memory in history that could soon exceed the capabilities of current hard drives by 1,000 times. [23] The team showed that the single-atom magnets can endure relatively high temperatures and strong external magnetic fields. The work could lead to the development of extremely high-density data storage devices. [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.

Stop Hacking by Supercomputers

Authors: George Rajna
Comments: 55 Pages.

IT experts at Monash University have devised the world's leading post-quantum secure privacy-preserving algorithm – so powerful it can thwart attacks from supercomputers of the future. [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. [32] "The realization of such all-optical single-photon devices will be a large step towards deterministic multi-mode entanglement generation as well as high-fidelity photonic quantum gates that are crucial for all-optical quantum information processing," says Tanji-Suzuki. [31] Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. [30] A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues. [29] A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality—a property of molecular spatial twist that defines its biochemical properties. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26]

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.

Quantum Entangled Internet

Authors: George Rajna

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.

Spin Wave Integrated Circuits

Authors: George Rajna
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.

Diamond String to Quantum Memory

Authors: George Rajna
Comments: 19 Pages.

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. To improve our understanding of the so-called quantum properties of materials, scientists at the TU Delft investigated thin slices of SrIrO3, a material that belongs to the family of complex oxides. [12] New research carried out by CQT researchers suggest that standard protocols that measure the dimensions of quantum systems may return incorrect numbers. [11] Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement? [10] A trio of scientists who defied Einstein by proving the nonlocal nature of quantum entanglement will be honoured with the John Stewart Bell Prize from the University of Toronto (U of T). [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories.

The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry.

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.

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.

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.

[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.

IBM Optical Receiver

Authors: George Rajna

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.

Phase-Change Memory Devices

Authors: George Rajna
Comments: 45 Pages.

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]

Cloud Quantum Computing

Authors: George Rajna
Comments: 54 Pages.

A team of researchers at Oak Ridge National Laboratory has demonstrated that it is possible to use cloud-based quantum computers to conduct quantum simulations and calculations. [34] Physicists have designed a new method for transmitting big quantum data across long distances that requires far fewer resources than previous methods, bringing the implementation of long-distance big quantum data transmission closer to reality. [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 Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns – dubbed polar vortices – in a synthetically layered material.

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.

Cozmo a New Lightweight Stream Cipher

Authors: Rhea Bonnerji, Simanta Sarkar, Krishnendu Rarhi, Abhishek Bhattacharya
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.

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

Authors: Jorma Jormakka
Comments: 14 Pages.

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.

Was the J. F. Kennedy Assassination a Conspiracy?

Authors: Jorma Jormakka
Comments: 10 Pages.

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.

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]

Differences in software environments can cause problems when those experiments need to be reproduced—so scientists at the MDC in Berlin are seeking a solution.

Towards Soliton Computer Based on Solitary Wave Solution of Maxwell-Dirac Equation: a Plausible Alternative to Manakov System

Authors: Victor Christianto, Florentin Smarandache
Comments: 7 Pages. This paper has not been submitted to a journal. Your comments are welcome

In recent years, there are a number of proposals to consider collision-based soliton computer based on certain chemical reactions, namely Belousov-Zhabotinsky reaction, which leads to soliton solutions of coupled Nonlinear Schroedinger equations. They are called Manakov System. But it seems to us that such a soliton computer model can also be based on solitary wave solution of Maxwell-Dirac equation, which reduces to Choquard equation. And soliton solution of Choquard equation has been investigated by many researchers, therefore it seems more profound from physics perspective. However, we consider both schemes of soliton computer are equally possible. More researches are needed to verify our proposition.

Store Data on Single Atom

Authors: George Rajna
Comments: 31 Pages.

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] For physicists, loss of magnetisation in permanent magnets can be a real concern. In response, the Japanese company Sumitomo created the strongest available magnet—one offering ten times more magnetic energy than previous versions—in 1983. [11] New method of superstrong magnetic fields' generation proposed by Russian scientists in collaboration with foreign colleagues. [10] By showing that a phenomenon dubbed the "inverse spin Hall effect" works in several organic semiconductors-including carbon-60 buckyballs-University of Utah physicists changed magnetic "spin current" into electric current. The efficiency of this new power conversion method isn't yet known, but it might find use in future electronic devices including batteries, solar cells and computers. [9] Researchers from the Norwegian University of Science and Technology (NTNU) and the University of Cambridge in the UK have demonstrated that it is possible to directly generate an electric current in a magnetic material by rotating its magnetization. [8] This paper explains the magnetic effect of the electric current from the observed effects of the accelerating electrons, causing naturally the experienced changes of the electric field potential along the electric wire. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the wave particle duality and the electron's spin also, building the bridge between the Classical and Quantum Theories. The changing acceleration of the electrons explains the created negative electric field of the magnetic induction, the changing relativistic mass and the Gravitational Force, giving a Unified Theory of the physical forces. Taking into account the Planck Distribution Law of the electromagnetic oscillators also, we can explain the electron/proton mass rate and the Weak and Strong Interactions.

High Frequency Chip

Authors: George Rajna
Comments: 37 Pages.

Novel, high-frequency electronic chip potentially capable of transmitting tens of gigabits of data per second—a rate that is orders of magnitude above the fastest internet speeds available today—has been developed by engineers at the University of California, Davis. [19] For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. [18] In early July, Google announced that it will expand its commercially available cloud computing services to include quantum computing. A similar service has been available from IBM since May. [17] Quantum computing is described as "just around the corner", simply awaiting the engineering prowess and entrepreneurial spirit of the tech sector to realise its full potential. [16] For the first time, physicists have demonstrated that hyperentangled photons can be transmitted in free space, which they showed by sending many thousands of these photons between the rooftops of two buildings in Vienna. [15] Now in a new study, physicists have cloned quantum states and demonstrated that, because the clones are entangled, it's possible to precisely and simultaneously measure the complementary properties of the clones. [14] Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are sufficiently concentrated and cooled. [13] The concept of temperature is critical in describing many physical phenomena, such as the transition from one phase of matter to another. Turn the temperature knob and interesting things can happen. But other knobs might be just as important for some studying some phenomena. One such knob is chemical potential, a thermodynamic parameter first introduced in the nineteenth century scientists for keeping track of potential energy absorbed or emitted by a system during chemical reactions. [12] For the first time, physicists have performed an experiment confirming that thermodynamic processes are irreversible in a quantum system—meaning that, even on the quantum level, you can't put a broken egg back into its shell. The results have implications for understanding thermodynamics in quantum systems and, in turn, designing quantum computers and other quantum information technologies. [11]

Error Concealment by Means of Motion Refinement and Regularized Bregman Divergence

Authors: Alessandra M. Coelho, Vania V. Estrela, Felipe P. do Carmo, Sandro R. Fernandes, V. V. Estrela, Vania Vieira Estrela
Comments: 8 Pages. Proceedings of the IDEAL 2012, Springer Verlag, 2012

This work addresses the problem of error concealment in video transmission systems over noisy channels employing Bregman divergences along with regularization. Error concealment intends to improve the effects of disturbances at the reception due to bit-errors or cell loss in packet networks. Bregman regularization gives accurate answers after just some iterations with fast convergence, better accuracy, and stability. This technique has an adaptive nature: the regularization functional is updated according to Bregman functions that change from iteration to iteration according to the nature of the neighborhood under study at iteration n. Numerical experiments show that high-quality regularization parameter estimates can be obtained. The convergence is sped up while turning the regularization parameter estimation less empiric, and more automatic.

Digital Information Without Loss

Authors: George Rajna
Comments: 18 Pages.

The researchers showed that the combination of these two properties can be used to transfer an encoded digital signal without information loss, which has potential applications for realizing highly efficient optical communication systems. [12] Physicists from the University of Würzburg have designed a light source that emits photon pairs, which are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape. [11] Quantum cryptography involves two parties sharing a secret key that is created using the states of quantum particles such as photons. The communicating parties can then exchange messages by conventional means, in principle with complete security, by encrypting them using the secret key. Any eavesdropper trying to intercept the key automatically reveals their presence by destroying the quantum states. [10] Optical photons would be ideal carriers to transfer quantum information over large distances. Researchers envisage a network where information is processed in certain nodes and transferred between them via photons. [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to build the Quantum Computer with the help of Quantum Information.

Photosynthesis Help Computer Technology

Authors: George Rajna
Comments: 57 Pages.

"From new ways of capturing and storing the energy coming to us from the Sun, to developing new forms of computing technology, this research opens up some exciting new opportunities." [30] Jiang and his team created a way to measure and control the energy differences of electron valley states in silicon quantum dots, which are a key component of quantum computing research. [29] Now, researchers at Stanford University and MIT have built a new chip to overcome this hurdle. [28] In the quest to make computers faster and more efficient, researchers have been exploring the field of spintronics—shorthand for spin electronics—in hopes of controlling the natural spin of the electron to the benefit of electronic devices. [27] When two researchers from the Swiss Federal Institute of Technology (ETH Zurich) announced in April that they had successfully simulated a 45-qubit quantum circuit, the science community took notice: it was the largest ever simulation of a quantum computer, and another step closer to simulating "quantum supremacy"—the point at which quantum computers become more powerful than ordinary computers. [26] Researchers from the University of Pennsylvania, in collaboration with Johns Hopkins University and Goucher College, have discovered a new topological material which may enable fault-tolerant quantum computing. [25] The central idea of TQC is to encode qubits into states of topological phases of matter (see Collection on Topological Phases). [24] One promising approach to building them involves harnessing nanometer-scale atomic defects in diamond materials. [23] Based on early research involving the storage of movies and documents in DNA, Microsoft is developing an apparatus that uses biology to replace tape drives, researchers at the company say. [22] Our brains are often compared to computers, but in truth, the billions of cells in our bodies may be a better analogy. The squishy sacks of goop may seem a far cry from rigid chips and bundled wires, but cells are experts at taking inputs, running them through a complicated series of logic gates and producing the desired programmed output.

Physics Solutions for Computational Problems

Authors: George Rajna
Comments: 17 Pages.

Researchers from the University of Central Florida and Boston University have developed a novel approach to solve such difficult computational problems more quickly. [29] By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists in Germany and the United States have gleaned new evidence about the possible causes of high-temperature superconductivity and similar phenomena. [28] Physicists have theoretically shown that a superconducting current of electrons can be induced to flow by a new kind of transport mechanism: the potential flow of information. [27] This paper explains the magnetic effect of the superconductive current from the observed effects of the accelerating electrons, causing naturally the experienced changes of the electric field potential along the electric wire. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the wave particle duality and the electron's spin also, building the bridge between the Classical and Quantum Theories. The changing acceleration of the electrons explains the created negative electric field of the magnetic induction, the Higgs Field, the changing Relativistic Mass and the Gravitational Force, giving a Unified Theory of the physical forces. Taking into account the Planck Distribution Law of the electromagnetic oscillators also, we can explain the electron/proton mass rate and the Weak and Strong Interactions. Since the superconductivity is basically a quantum mechanical phenomenon and some entangled particles give this opportunity to specific matters, like Cooper Pairs or other entanglements, as strongly correlated materials and Exciton-mediated electron pairing, we can say that the secret of superconductivity is the quantum entanglement.

Engineering researchers at the University of Minnesota have developed a revolutionary process for 3D printing stretchable electronic sensory devices that could give robots the ability to feel their environment. The discovery is also a major step forward in printing electronics on real human skin. [18] Researchers from France and the University of Arkansas have created an artificial synapse capable of autonomous learning, a component of artificial intelligence. [17] Intelligent machines of the future will help restore memory, mind your children, fetch your coffee and even care for aging parents. [16] Unlike experimental neuroscientists who deal with real-life neurons, computational neuroscientists use model simulations to investigate how the brain functions. [15] A pair of physicists with ETH Zurich has developed a way to use an artificial neural network to characterize the wave function of a quantum many-body system. [14] A team of researchers at Google's DeepMind Technologies has been working on a means to increase the capabilities of computers by combining aspects of data processing and artificial intelligence and have come up with what they are calling a differentiable neural computer (DNC.) In their paper published in the journal Nature, they describe the work they are doing and where they believe it is headed. To make the work more accessible to the public team members, Alexander Graves and Greg Wayne have posted an explanatory page on the DeepMind website. [13] Nobody understands why deep neural networks are so good at solving complex problems. Now physicists say the secret is buried in the laws of physics.

In their paper published in the journal Nature, the team describes how they built their chip and what capabilities it has.

Introduction to Logplex Encoding

Authors: Russell Leidich
Comments: 5 Pages.

Logplex codes are universal codes, that is, bitstrings which map one-to-one to the whole numbers, regardless of the bits which follow them in memory. The codes are dense, in the sense that there is no finite series of bits which does not map to at least one whole number. Their asymptotic efficiency (size out divided by size in) is one, as with Elias omega codes[1], but they have some convient features absent in the latter: Given whole numbers M and N. If (M<N) then (logplex(M)<logplex(N)). This provides for more efficient searching and sorting, as such tasks can be done without the need to allocate separate memory for the corresponding decoded whole numbers. For all nonzero M, M itself is encoded verbatim in the high bits of its logplex. In all cases, the high (last) bit of a logplex is one. Representation of all subparts of logplexes are bitwise little endian. This is in contrast to Elias omega codes, the endianness of the subparts of which are opposite to the expansion direction. Finally, logplexes are scale-agnostic: there is no need to assume that (log 2 M) has any particular maximum value. This feature stems from their recursive structure, which is analogous to that of Elias omega codes.

Introduction to Agnentropy

Authors: Russell Leidich
Comments: 28 Pages.

Claude Shannon[1] devised a way to quantify the information entropy[2] of a finite integer set, given the probabilities of finding each integer in the set. Information entropy, hereinafter simply "entropy", refers to the number of bits required to encode some such set in a given numerical base (usually binary). Unfortunately, his formula for the "Shannon entropy" seems to have been widely misappropriated as a means by which to measure the entropy of such sets by supplanting the probability coefficients (which are generally unknowable) with the normalized frequencies of the integers as they actually occur in the set. This practice is so common that Shannon entropy is often defined in precisely this manner, and indeed this is how we define it here. However, the inaccuracy induced by this compromise may lead to erroneous conclusions, especially when very short or faint signals are concerned. To make matters worse, the numerical behavior of Shannon entropy formula is rather unstable over large sets, where otherwise it would be more accurate. Herein we introduce the concept of agnentropy, short for "agnostic entropy", in the sense of an entropy metric which begins with almost no assumptions about the set under analysis. (Technically, it's a "divergence" -- essentially a Kullback-Leibler divergence[3] without the implicit singularies -- because it fails the triangle inequality. We refer to it as a "metric" only in the qualitative sense that it measures something.) This stands in stark contrast to the (compromised) Shannon entropy, which presupposes that the frequencies of integers within a given set are already known. In addition to being more accurate when used appropriately, agnentropy is also more numerically stable and faster to compute than Shannon entropy. To be precise, Shannon entropy does not measure the number of bits in an invertibly compressed code. It is, more accurately, an underestimation of that value. Unfortunately, the margin of underestimation is not straightforwardly computable, and has a size O(Z), where Z is the number of unique integers in the set, assuming that said integers are of predetermined maximum size. By contrast, agnentropy underestimates that bit count by no more than 2, plus the size of 2 logplexes. (Logplexes are universal (affine) codes introduced in [8].) In practice, this overhead amounts to tens of bits, as opposed to potentially thousands of bits for Shannon. This difference has meaningful ramifications for the optimization of both lossless and lossy compression algos.

Introduction to Entropy Transforms

Authors: Russell Leidich
Comments: 34 Pages.

We have at our disposal a wide variety of discrete transforms for the discovery of "interesting" signals in discrete data sets in any number of dimensions, which are of particular utility when the default assumption is that the set is mundane. SETI, the Search for Extraterrestrial Intelligence, is the archetypical case, although problems in drug discovery, malware detection, financial arbitrage, geologic exploration, forensic analysis, and other diverse fields are perpetual clients of such tools. Fundamentally, these include the Fourier, wavelet, curvelet, wave atom, contourlet, brushlet, etc. transforms which have churned out of math departments with increasing frequency since the days of Joseph Fourier. A mountain of optimized applications has been built on top of them, for example the Fastest Fourier Transform in the West[1] and the Wave Atom Toolbox[2]. Such transforms excel at discovering particular classes of signals. So much so that the return on investment in new math would appear to be approaching zero. What's missing, however, is efficiency: the question must be asked as towhen such transforms are computationally justifiable. Herein we investigate a preprocessing technique, abstractly known as an "entropy transform", which, in a wide variety of practical applications, can discern in essentially real time whether or not an "interesting" signal exists within a particular data set. (Entropy transforms say nothing as to the nature of the signal, but merely how interesting a particular subset of the data appears to be.) Entropy transforms have the added advantage that they can also be tuned to behave as crude classifiers -- not as good as their deep learning counterparts, but requiring orders of magnitude less processing power. In applications where identifying many targets with moderate accuracy is more important than identifying a few targets with excellent accuracy, entropy transforms could bridge the gap to product viability. It would be fair to say that in the realm of signal detection, discrete transforms should be the tool of choice because they tend to produce the most accurate and well characterized results. But processor power and execution time are not free! Particularly when, as in the case of SETI, the bottleneck is the rate at which newly acquired data can be processed, a more productive approach would be use to cheap but reasonably accurate O(N) transforms to filter out all but the most surprising subsets of the data. This would reserve processing capacity for those rare weird cases more deserving of closer inspection. I published Agnentro[3], an open-source toolkit for signal search and comparison. The reason, first and foremost, was to support these broad and rather unintuitive assertions with numerical evidence. The goal of this paper is to formalize the underlying math.

OPRA Technique for M-QAM over Nakagami-m Fading Channel with Imperfect CSI

Authors: Mr. Bhargabjyoti Saikia1, Rupaban Subadar†2
Comments: 12 Pages.

Analysis of an Optimum Power and Rate Adaptation (OPRA) technique has been carried out for Multilevel-Quadrature Amplitude Modulation (M-QAM) over Nakagami-m ?at fading channels considering an imperfect channel estimation at the receiver side. The optimal solution has been derived for a continuous adaptation, which is a specific bound function and not possible to express in close mathematical form. Therefore, a sub-optimal solution is derived for the continuous adaptation and it has been observed that it tends to the optimum solution as the correlation coefficient between the true channel gain and its estimation tends to one. It has been observed that the receiver performance degrades with an increase in estimation error.

Comments: 8 Pages.

In emerging world of cloud computing gives wide range of functionalities. Personal Health Record (PHR) enables patients to store, share, and access personal health data in centralized way that it can be accessible from anywhere and anytime. One major problem in the existing work is the cloud to manage and secure data from the unauthorized persons. However, combining of PHR with cloud gives new horizons for medical eldest to be digitalized in centralized storage but it comes with major concern as security. There are many researchers are work in securing PHR which stored in cloud using nave approaches but it’s not enough to secure it. So there is need for new technology as Attribute based Encryption that secure PHR with providing many functionalities such as accountability, revocation of user, searching over encrypted les, delegation of other user access, searching over encrypted les, multi-authority and many more.

Soft Starter of Single Phase Pump Motor

Authors: Rai Shailesh, Dubey Jayesh, Gupta Ajay
Comments: 2 Pages. Thank You for providing us platform to explore our project idea.

In single-phase induction motor of ratings beyond a certain limit of withstand take very large currents and low powe factor while being started directly from a 1-phase supply. In order to mitigate the adverse effects of starting torque transients and high inrush currents in induction motors, a popular method is to use electronically controlled soft-starting voltages utilizing TRIAC. Normally soft-starters are used for avoiding this problem and to achieve smooth starting of large capacity induction motors. Soft starters use ac voltage controllers to start the induction motor and to adjust its speed. The performance of a voltage controlled large induction motor soft starter has been improved, resulting in nearly perfect current and torque profiles. Soft starters are used as induction motor controllers in compressors, blowers, fans, pumps, mixers, crushers and grinders, and many other applications. Starting torque pulsations are eliminated by triggering back-to-back-connected TRIAC at proper points on the first supply voltage cycle. The soft starter is connected in motor drive during the starting condition only and once the motor get its rated speed then the soft starter is disconnected from the main motor system so that the motor get protected.

From One to Many: Synced Hash-Based Signatures

Authors: Santi J. Vives Maccallini
Comments: 16 Pages.

Hash-based signatures use a one-time signature (OTS) as its main building block, and transform it into a many-times scheme, to sign a larger number of signatures. In known constructions, the cost and the size of each signature increases as the number of needed signatures grows. In real-world applications, requiring a significant number of signatures, the signatures can get quite large. As a result, it is usually believed that post-quantum signatures based on hashes need more computation and much larger sizes than classical signatures. We introduce a construction to challenge that idea: we show that it is possible to construct a many-times signatures scheme that is more efficient than the OTS it is built from, rather than less. We study the generation of signatures in conjunction with a blockchain, like bitcoin. The proposed scheme permits an unlimited number of signatures. The size of each signatures is constant and the same as in the OTS. The verification cost starts the same as in the OTS and decreases with each new signature, becoming more efficient on average as the number of signatures grows. Keywords: many-time signatures, hash, post-quantum cryptography, authentication, blockchain, bitcoin, optimization.

[13] Nobody understands why deep neural networks are so good at solving complex problems. Now physicists say the secret is buried in the laws of physics. [12] A team of researchers working at the University of California (and one from Stony Brook University) has for the first time created a neural-network chip that was built using just memristors. In their paper published in the journal Nature, the team describes how they built their chip and what capabilities it has. [11] A team of researchers used a promising new material to build more functional memristors, bringing us closer to brain-like computing. Both academic and industrial laboratories are working to develop computers that operate more like the human brain. Instead of operating like a conventional, digital system, these new devices could potentially function more like a network of neurons.

[8] Physicists at the Universities of Bonn and Cambridge have succeeded in linking two completely different quantum systems to one another. In doing so, they have taken an important step forward on the way to a quantum computer. To accomplish their feat the researchers used a method that seems to function as well in the quantum world as it does for us people: teamwork.

Magnetic Tunnel Junctions

Authors: George Rajna
Comments: 41 Pages.

For the last two decades, magnetic tunnel junctions (MTJs) have played a central role in spintronic devices such as read heads of hard disk drives and nonvolatile magnetoresistive random access memories (MRAMs), and researchers are constantly working to improve their performance. [24] Magnetic materials are a vital ingredient in the components that store information in computers and mobile phones. Now, A*STAR researchers have developed a material that could help these magnetic-based memory devices to store and retrieve data faster while using less power. [23] A team of researchers with members from institutions in Germany and Israel has developed a way to launch plasmons with controlled amounts of angular momentum using spiral-like structures fashioned into a smooth layer of gold plate. [22] Work at the New York Genome Centre represents a big step towards DNA-based information storage. Andrew Masterson reports. [21] At Caltech, a group of researchers led by Assistant Professor of Bioengineering Lulu Qian is working to create circuits using not the usual silicon transistors but strands of DNA.

Nanologic Computing

Authors: George Rajna

Scientists have built tiny logic machines out of single atoms that operate completely differently than conventional logic devices do. [18] Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today's electronics. [17] Physicists from the Faculty of Physics at the University of Warsaw have developed a holographic atomic memory device capable of generating single photons on demand in groups of several dozen or more. The device, successfully demonstrated in practice, overcomes one of the fundamental obstacles towards the construction of a quantum computer. [16] Random number generators are crucial to the encryption that protects our privacy and security when engaging in digital transactions such as buying products online or withdrawing cash from an ATM. For the first time, engineers have developed a fast random number generator based on a quantum mechanical process that could deliver the world's most secure encryption keys in a package tiny enough to use in a mobile device. [15] Researchers at the University of Rochester have moved beyond the theoretical in demonstrating that an unbreakable encrypted message can be sent with a key that's far shorter than the message—the first time that has ever been done. [14] Quantum physicists have long thought it possible to send a perfectly secure message using a key that is shorter than the message itself. Now they've done it. [13] What once took months by some of the world's leading scientists can now be done in seconds by undergraduate students thanks to software developed at the University of Waterloo's Institute for Quantum Computing, paving the way for fast, secure quantum communication. [12] The artificial intelligence system's ability to set itself up quickly every morning and compensate for any overnight fluctuations would make this fragile technology much more useful for field measurements, said co-lead researcher Dr Michael Hush from UNSW ADFA.

Computer Grows as Computes

Authors: George Rajna
Comments: 38 Pages.

Researchers from The University of Manchester have shown it is possible to build a new super-fast form of computer that "grows as it computes". [21] At Caltech, a group of researchers led by Assistant Professor of Bioengineering Lulu Qian is working to create circuits using not the usual silicon transistors but strands of DNA. [20] Researchers have introduced a new type of "super-resolution" microscopy and used it to discover the precise walking mechanism behind tiny structures made of DNA that could find biomedical and industrial applications. [19] Genes tell cells what to do—for example, when to repair DNA mistakes or when to die—and can be turned on or off like a light switch. Knowing which genes are switched on, or expressed, is important for the treatment and monitoring of disease. Now, for the first time, Caltech scientists have developed a simple way to visualize gene expression in cells deep inside the body using a common imaging technology. [18] Researchers at The University of Manchester have discovered that a potential new drug reduces the number of brain cells destroyed by stroke and then helps to repair the damage. [17] Researchers at the University of Connecticut have uncovered new information about how particles behave in our bloodstream, an important advancement that could help pharmaceutical scientists develop more effective cancer drugs. [16] For the past 15 years, the big data techniques pioneered by NASA's Jet Propulsion Laboratory in Pasadena, California, have been revolutionizing biomedical research. On Sept. 6, 2016, JPL and the National Cancer Institute (NCI), part of the National Institutes of Health, renewed a research partnership through 2021, extending the development of data science that originated in space exploration and is now supporting new cancer discoveries. [15] IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could enable physicians to detect diseases such as cancer before symptoms appear. [14] Scientists work toward storing digital information in DNA. [13] Leiden theoretical physicists have proven that DNA mechanics, in addition to genetic information in DNA, determines who we are. Helmut Schiessel and his group simulated many DNA sequences and found a correlation between mechanical cues and the way DNA is folded. They have published their results in PLoS One. [12] We model the electron clouds of nucleic acids in DNA as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbours resulting in a van der Waals type bonding. [11] Scientists have discovered a secret second code hiding within DNA which instructs cells on how genes are controlled. The amazing discovery is expected to open new doors to the diagnosis and treatment of diseases, according to a new study. [10] There is also connection between statistical physics and evolutionary biology, since the arrow of time is working in the biological evolution also. From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. [8] This paper contains the review of quantum entanglement investigations in living systems, and in the quantum mechanically modeled photoactive prebiotic kernel systems. [7] The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron’s spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

A Study on the Effect of Regularization Matrices in Motion Estimation

Authors: Vania Vieira Estrela, A. M. Coelho, Vania V. Estrela
Comments: 21 Pages. Int J Comput Appl. 2012 August 1; 51(19): 17–24. doi:10.5120/8151-1886

Inverse problems are very frequent in computer vision and machine learning applications. Since noteworthy hints can be obtained from motion data, it is important to seek more robust models. The advantages of using a more general regularization matrix such as Λ=diag{λ1,…,λK} to robustify motion estimation instead of a single parameter λ (Λ=λI) are investigated and formally stated in this paper, for the optical flow problem. Intuitively, this regularization scheme makes sense, but it is not common to encounter high-quality explanations from the engineering point of view. The study is further confirmed by experimental results and compared to the nonregularized Wiener filter approach. Int J Comput Appl. 2012 August 1; 51(19): 17–24. doi:10.5120/8151-1886

Data Transfer Efficiency Record

Authors: George Rajna
Comments: 38 Pages.

Researchers at the Department of Energy's Oak Ridge National Laboratory have set a new record in the transfer of information via superdense coding, a process by which the properties of particles like photons, protons and electrons are used to store as much information as possible. [27] An international team, led by a scientist from the University of Sussex, have today unveiled the first practical blueprint for how to build a quantum computer, the most powerful computer on Earth. [26] Data centers are the central point of many, if not most, information systems today, but the masses of wires interconnecting the servers and piled high on racks begins to resemble last year's tangled Christmas-tree lights disaster. Now a team of engineers is proposing to eliminate most of the wires and substitute infrared free-space optics for communications. [25] Characterising quantum channels with non-separable states of classical light the researchers demonstrate the startling result that sometimes Nature cannot tell the difference between particular types of laser beams and quantum entangled photons. [24] Physicists at Princeton University have revealed a device they've created that will allow a single electron to transfer its quantum information to a photon. [23] A strong, short light pulse can record data on a magnetic layer of yttrium iron garnet doped with Co-ions. This was discovered by researchers from Radboud University in the Netherlands and Bialystok University in Poland. The novel mechanism outperforms existing alternatives, allowing the fastest read-write magnetic recording accompanied by unprecedentedly low heat load. [22] It goes by the unwieldy acronym STT-MRAM, which stands for spin-transfer torque magnetic random access memory. [21] Memory chips are among the most basic components in computers. The random access memory is where processors temporarily store their data, which is a crucial function. Researchers from Dresden and Basel have now managed to lay the foundation for a new memory chip concept. [20] Researchers have built a record energy-efficient switch, which uses the interplay of electricity and a liquid form of light, in semiconductor microchips. The device could form the foundation of future signal processing and information technologies, making electronics even more efficient. [19]

An Enhanced Ssvep Bci Application Through Emotion: Preliminary Results

Authors: Hadi Oqaibi, Anas Fattouh
Comments: 10 Pages. International Journal of Innovative Research in Computer and Communication Engineering

Steady-state visual evoked potential (SSVEP) is a well-established paradigm of brain-computer interface (BCI) where the interaction between the user and a controlled device is achieved via brainwave activities and visual stimuli. Although SSVEP-based BCIs are known to have high information transfer rate (ITR), wrong feedback reduces the performance of these applications. In this paper, we investigate the possibility of enhancing SSVEP -based BCI applications by incorporating the user’s emotions. To this end, an SSVEP-based BCI application is designed and implemented where the user has to steer a simulated car moving through a maze to reach a target position. Using standard flickering checkerboards, the user has to select one of two commands, turn right or turn left. After each selection, a visual virtual feedback is shown and the emotional state of the user is estimated from recorded electroencephalogram (EEG) brain activities. This estimated emotion could be used to automatically confirm or cancel the selected command and therefore improve the quality of executed commands.

Ds-Bidens: a Novel Computer Program for Studying Bacterial Colony Features

Authors: Enrique Marcet, Manuel Medell-Gago
Comments: 4 Pages.

Optical forward-scattering systems supported by image analysis methods are increasingly being used for rapid identification of bacterial colonies (Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio cholera, etc.). The conventional detection and identification of bacterial colonies comprises a variety of methodologies based on biochemical, serological or DNA/RNA characterization. Such methods involve laborious and time-consuming procedures in order to achieve confirmatory results. In this article we present ds-Bidens, a novel software for studying bacterial colony features. The software ds-Bidens was programmed using C++, Perl and wxBasic programming languages. A graphical user interface (GUI), an image processing tool and functions to compute bacterial colony features were programmed. We obtained versatile software that provides key tools for studying bacterial colony images as: texture analysis, invariant moment and color (CIELab) calculation, etc., simplifying operations previously carried out by MATLAB applications. The new software can be of particular interest in fields of microbiology, both for bacterial colonies identification and the study of their growth, changes in color and textural features. Additionally ds-Bidens offers to the users a versatile environment to study bacterial colonies images. ds-Bidens is freely available from: http://ds-bidens.sourceforge.net/

Comments: 14 Pages.

Over the few decades, the Communication Technology has evolved surprisingly. The data rate, the reliability and multiple access supported by wireless digital communication are very interesting. Accessibility of worldwide information from a remote area via digital signals is not less than any boon for human beings. Receiving information from a far satellite at home at TV screen via STB gave a new dimension to the entertainment world. This success story is further leading to the next generation (G) Internet of Thing (IoT) services for Global communication and M2M (Machine to Machine) communication. With the recent innovation in satellite communication, our Homes are getting SMART. Homes will be blessed by satellite based IoT at very low cost. IoT services will be provided by Satellite, 5G mobile and other competitive technologies. These technologies will enable us to get live interaction via smart devices of our smart home, to control and access our home appliances from anywhere throughout the world with its ubiquitous features. Transmission and Reception of signals from Home to Satellite via DVB-S2 and Indoor distribution of signals via Wi-Fi n within rooms of the Smart Homes is the basic concept behind this idea. Uplink from home will be introduced soon with help of smart LNB using Millimeter wave RF carrier of 30 GHz. This paper presents a cloud centric vision for implementation of IOT services in Smart Homes. DVB-S2 Transmitter, DVB-S2 Receiver and Wi-Fi n with input signal is analyzed on Agilent SystemVue and then synchronized with Agilent Vector Signal Analyzer (VSA) to check and verify the Output Response of the designed Smart Home system.

Evolution of Modern Communication Systems

Authors: Krishn Kumar Gupt, Vinay Kumar Singh
Comments: 6 Pages.

Modern communications technology revolutionized the way, mobility and efficiency of electronic communications. Starting from with Alexander Graham Bells’ telephone experiments to widely practiced W-CDMA network and the nearly achieved 4G mode of communications, all had and will have great contributions in today’s voice/data network arena. Wireless technology has achieved evolutionary success aiming at unified target: efficiency, performance and feasibility in high mobile environment. The mobile experience is expanding everywhere fulfilling the basic electronic communication needs. The first generation (1G) was analog. 1G established seamless mobile connectivity used for basic mobile voice until being replaced by the second generation (2G) digital telecommunications technologies which increased voice capacity delivering mobile to the masses with network infrastructure supporting text messaging. The success of digital voice and simple data prompted to the development of cellular wireless communication system with improved data connectivity and more accessible features leads to followed by the third generation (3G). Third generation system having mobile optimization for data enabling mobile broadband services with better and higher speed of data transfer and connectivity. The fourth generation (4G) having more capacity for faster and better wireless mobile broadband experiences with accessing capability to wide range of communication services, including advanced mobile services, and enhancement in the quality of services with increase in the bandwidth. In this paper we address the evolution of wireless modern mobile communication systems, from first generation (1G) to the widely practiced third generation (3G), recently introduced fourth generation (4G) and some glimpse of foreseeable future of fifth generation (5G).

We explore and apply methods of image analization in several forms in order to monitor the condition and health of a crowd. Stampedes, congestion, and traffic all occur as a result of inefficient crowd management. Our software identifies congested areas and determines solutions to avoid congestion based on live data. The data is then processed by a local device which is fed via camera. This method was tested in simulation and proved to create a more efficient and congestion-free scenario. Future plans include depth sensing for automatic calibration and suggested course of action.

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).

Introduction to Entropy Transforms

Authors: Russell Leidich
Comments: 37 Pages.

We have at our disposal a wide variety of discrete transforms for the discovery of "interesting" signals in discrete data sets in any number of dimensions, which are of particular utility when the default assumption is that the set is mundane. SETI, the Search for Extraterrestrial Intelligence, is the archetypical case, although problems in drug discovery, malware detection, financial arbitrage, geologic exploration, forensic analysis, and other diverse fields are perpetual clients of such tools. Fundamentally, these include the Fourier, wavelet, curvelet, wave atom, contourlet, brushlet, etc. transforms which have churned out of math departments with increasing frequency since the days of Joseph Fourier. A mountain of optimized applications has been built on top of them, for example the Fastest Fourier Transform in the West[1] and the Wave Atom Toolbox[2]. Such transforms excel at discovering particular classes of signals. So much so that the return on investment in new math would appear to be approachingzero. What's missing, however, is efficiency: the question must be asked as to when such transforms are computationally justifiable. Herein we investigate a preprocessing technique, abstractly known as an "entropy transform", which, in a wide variety of practical applications, can discern in essentially real time whether or not an "interesting" signal exists within a particular data set. (Entropy transforms say nothing as to the nature of the signal, but merely how interesting a particular subset of the data appears to be.) Entropy transforms have the added advantage that they can also be tuned to behave as crude classifiers – not as good as their deep learning counterparts, but requiring orders of magnitude less processing power. In applications where identifying many targets with moderate accuracy is more important than identifying a few targets with excellent accuracy, entropy transforms could bridge the gap to product viability. It would be fair to say that in the realm of signal detection, discrete transforms should be the tool of choice because they tend to produce the most accurate and well characterized results. But processor power and execution time are not free! Particularly when, as in the case of SETI, the bottleneck is the rate at which newly acquired data can be processed, a more productive approach would be use to cheap but reasonably accurate O(N) transforms to filter out all but the most surprising subsets of the data. This would reserve processing capacity for those rare weird cases more deserving of closer inspection. I published Agnentro[3], an open-source toolkit for signal search and comparison. The reason, first and foremost, was to support these broad and rather unintuitive assertions with numerical evidence. The goal of this paper is to formalize the underlying math.

Integer Compositions Signatures

Authors: Santi J. Vives Maccallini
Comments: First Publication: 2016-Oct-24. Current Version: 2. Pages: 6. Language: English.

We introduce integer compositions signatures (ic): a post-quantum, hash-based family of one-time signatures. The proposed scheme explores a connection between hash-based signatures and combinatorics: the authentication path taken from the signature to the public key is determined by a restricted composition of an 9. The family shows improvements over previous schemes like Winternitz: reduced cost, verification in constant time, and the possibility to tweak the signature for either faster signing or faster verification. Keywords: one-time signatures, ots, hash, authentication, post-quantum cryptography, composition, combinatorics.
