A group of scientists from the Max Planck Institutes in Halle and Dresden have discovered a new kind of magnetic nano-object in a novel material that could serve as a magnetic bit with cloaking properties to make a magnetic disk drive with no moving parts - a Racetrack Memory - a reality in the near future. [19]
Jarvis Loh, Gan Chee Kwan and Khoo Khoong Hong from the Agency for Science, Technology and Research (A*STAR) Institute of High Performance Computing, Singapore, have modeled these minute spin spirals in nanoscopic crystal layers. [18]
Some of the world's leading technology companies are trying to build massive quantum computers that rely on materials super-cooled to near absolute zero, the theoretical temperature at which atoms would cease to move. [17]
While technologies that currently run on classical computers, such as Watson, can help find patterns and insights buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen because the data doesn't exist and the possibilities that you need to explore to get to the answer are too enormous to ever be processed by classical computers. [16]
Through a collaboration between the University of Calgary, The City of Calgary and researchers in the United States, a group of physicists led by Wolfgang Tittel, professor in the Department of Physics and Astronomy at the University of Calgary have successfully demonstrated teleportation of a photon (an elementary particle of light) over a straight-line distance of six kilometers using The City of Calgary's fiber optic cable infrastructure. [15]
Optical quantum technologies are based on the interactions of atoms and photons at the single-particle level, and so require sources of single photons that are highly indistinguishable – that is, as identical as possible. Current single-photon sources using semiconductor quantum dots inserted into photonic structures produce photons that are ultrabright but have limited indistinguishability due to charge noise, which results in a fluctuating electric field. [14]
A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department of Energy's Oak Ridge National Laboratory. [13]
A source of single photons that meets three important criteria for use in quantum-information systems has been unveiled in China by an international team of physicists. Based on a quantum dot, the device is an efficient source of photons that emerge as solo particles that are indistinguishable from each other. The researchers are now trying to use the source to create a quantum computer based on "boson sampling". [11]
With the help of a semiconductor quantum dot, physicists at the University of Basel have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream of identical photons. [10]

The authors have recently shown that recognizing low fractional hypertree-width (fhw) is NP-complete
in the general case and that the problem becomes tractable if the hypergraphs under consideration have degree and intersection width bounded by a constant, i.e., every vertex is contained in only constantly many different edges and the intersection of two edges contains only constantly many vertices. In this article, we show that bounded degree alone suffices to ensure tractability.

Concepts for information storage and logical processing based on magnetic domain walls have great potential for implementation in future information and communications technologies." [21] Research at the National Institute of Standards and Technology (NIST) suggests it also may be true in the microscopic world of computer memory, where a team of scientists may have found that subtlety solves some of the issues with a novel memory switch. [20] Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths. [19] In their paper published in Nature, the team demonstrates that photons can become an accessible and powerful quantum resource when generated in the form of colour-entangled quDits. [18] But in the latest issue of Physical Review Letters, MIT researchers describe a new technique for enabling photon-photon interactions at room temperature, using a silicon crystal with distinctive patterns etched into it. [17] Kater Murch's group at Washington University in St. Louis has been exploring these questions with an artificial atom called a qubit. [16] Researchers have studied how light can be used to observe the quantum nature of an electronic material. [15] An international team of researchers led by the National Physical Laboratory (NPL) and the University of Bern has revealed a new way to tune the functionality of next-generation molecular electronic devices using graphene. [14] Researchers at the Department of Physics, University of Jyväskylä, Finland, have created a theory that predicts the properties of nanomagnets manipulated with electric currents. This theory is useful for future quantum technologies. [13] Quantum magnetism, in which – unlike magnetism in macroscopic-scale materials, where electron spin orientation is random – atomic spins self-organize into one-dimensional rows that can be simulated using cold atoms trapped along a physical structure that guides optical spectrum electromagnetic waves known as a photonic crystal waveguide.

We also show several techniques observed by the minimum element, we call a logical minimum. The perfect zero-knowledge technique will deliver exactly the same. We conclude with a demonstration of the halting problem.

Over millennia, nature has evolved an incredible information storage medium – DNA. It evolved to store genetic information, blueprints for building proteins, but DNA can be used for many more purposes than just that. [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. [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]

In this paper, we propose a two-phase Content-Based Retrieval System for images embedded in the Neutrosophic domain. In this first phase, we extract a set of features to represent the content of each image in the training database. In the second phase, a similarity measurement is used to determine the distance between the image under consideration (query image), and each image in the training database, using their feature vectors constructed in the first phase. Hence, the N most similar images are retrieved.

We utilize a previously reported methodological framework [5], to find a general set of mappings for any satisfiability (SAT) problem to a set of arithmetized codes allowing a classification hierarchy enumerable via integer partition functions. This reveals a unique unsatisfiability criterion via the introduction of certain universal indicator functions associating the validity of any such problem with a mapping between Mersenne integers and their complements in an inclusive hierarchy of exponential intervals. Lastly, we present means to reduce the complexity of the original problem to that of a special set of binary sequences and their bit block analysis via a reduction of any expression to a type of a Sequential Dynamical System (SDS) using the technique of clause equalization. We specifically notice the apparent analogy of certain dynamical properties behind such problems with resonances and coherencies of multi-periodic systems leading to the possibility of certain fast analog or natural implementations of dedicated SAT-machines. A Matlab toolbox is also offered as additional aid in exploring certain simple examples.

Chemists at Case Western Reserve University have found a way to possibly store digital data in half the space current systems require. [12] Using lasers to make data storage faster than ever. [11] Some three-dimensional materials can exhibit exotic properties that only exist in "lower" dimensions. For example, in one-dimensional chains of atoms that emerge within a bulk sample, electrons can separate into three distinct entities, each carrying information about just one aspect of the electron's identity—spin, charge, or orbit. The spinon, the entity that carries information about electron spin, has been known to control magnetism in certain insulating materials whose electron spins can point in any direction and easily flip direction. Now, a new study just published in Science reveals that spinons are also present in a metallic material in which the orbital movement of electrons around the atomic nucleus is the driving force behind the material's strong magnetism. [10] Currently studying entanglement in condensed matter systems is of great interest. This interest stems from the fact that some behaviors of such systems can only be explained with the aid of entanglement. [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.

Aiming at the special circumstance in which UAVs swarm are used in the mode of battlefield extending, a message delivery scheme called AWJPMMD (ARIMA-WNN Joint Prediction Model based Message Delivery) is proposed. In this scheme, the LET (Link Expiration Time) of the center node and the proxy node is calculated by high precision GPS information, then the LET at next moment is predicted by ARIMA-WNN (Autoregressive Integrated Moving Average model - Wavelet Neural Network) Joint Prediction Model. Finally, the process of message delivery is affected by the predicted value of LET and other parameters. The target information is sent to the UAVs ground station in form of store-and-forward by the message delivery process. Simulation shows that this scheme can provide higher message delivery ratio and this scheme is more stable.

With the fast advancement in the field of network security everything gets the chance to be possible on web. Remote user authentication is an imperative system in the networks framework to check the exactitude of remote user over the public channel. In this authentication procedure, server checks accreditation of the user that user is authentic and legal one or not. For that Server and user commonly confirm each other and make a same session key for encryption of upcoming conversations. There are two types of authentication: Single server and Multi server. To overcome the drawback of single server authentication (remembering id and pswd for accessing each of the server), the concept of Multi server comes, in which user first register with RC, and whatever servers are registerd under RC can be accessed by user by providing single id and pswd for all. Here We review US patent [US 9264425 B1] scheme which is based on Multi server authentication, we provide mathematical analysis of the same with some attacks found on it.

The challenge of this paper is to relate quantum-inspired dynamics represented by a self- supervised system, to solutions of noncomputable problems. In the self-supervised systems, the role of actuators is played by the probability produced by the corresponding Liouville equation. Following the Madelung equation that belongs to this class, non- Newtonian properties such as randomness, entanglement, and probability interference typical for quantum systems have been described in [1]. It has been demonstrated there, that such systems exist in the mathematical world: they are presented by ODE coupled with their Liouville equation, but they belong neither to Newtonian nor to quantum physics. The central point of this paper is the application of the self-supervised systems to solve traveling salesman problem.

The researchers, in their paper published in Science Advances, say this freedom allows quantum computers to store many different states of the system being simulated in different superpositions, using less memory overall than in a classical computer. [26] The advancement of quantum computing faces a tremendous challenge in improving the reproducibility and robustness of quantum circuits. One of the biggest problems in this field is the presence of noise intrinsic to all these devices, the origin of which has puzzled scientists for many decades. [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] The magnetic structure of a skyrmion is symmetrical around its core; arrows indicate the direction of spin. [18]

Area detectors are used in many scientific and technological applications such as particle and radiation physics. Thanks to the recent technological developments, the radiation sources are becoming increasingly brighter and the detectors become faster and more efficient. The result is a sharp increase in the size of data collected in a typical experiment. This situation imposes a bottleneck on data processing capabilities, and could pose a real challenge to scientific research in certain areas. This article proposes a number of simple techniques to facilitate rapid and efficient extraction of data obtained from these detectors. These techniques are successfully implemented and tested in a computer program to deal with the extraction of X-ray diffraction patterns from EDF image files obtained from CCD detectors.

Collatz' conjecture (stated in 1937 by Collatz and also named Thwaites conjecture, or Syracuse, 3n+1 or oneness problem) can be described as follows:
Take any positive whole number N. If N is even, divide it by 2. If it is odd, multiply it by 3 and add 1. Repeat this process to the result over
and over again. Collatz' conjecture is the supposition that for any positive integer N, the sequence will invariably reach the value 1.
The main contribution of this paper is to present a new approach to Collatz' conjecture. The key idea of this new approach is to clearly differentiate
the role of the division by two and the role of what we will name here the jump: a = 3n + 1.
With this approach, the proof of the conjecture is given as well as generalizations for jumps of the form qn + r and for jumps being polynomials
of degree m >1.

EPFL scientists have developed a new perovskite material with unique properties that can be used to build next-generation hard drives. [16] Scientists have fabricated a superlattice of single-atom magnets on graphene with a density of 115 terabits per square inch, suggesting that the configuration could lead to next-generation storage media. [15] Now a researcher and his team at Tyndall National Institute in Cork have made a 'quantum leap' by developing a technical step that could enable the use of quantum computers sooner than expected. [14] A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department of Energy's Oak Ridge National Laboratory. [13] A source of single photons that meets three important criteria for use in quantum-information systems has been unveiled in China by an international team of physicists. Based on a quantum dot, the device is an efficient source of photons that emerge as solo particles that are indistinguishable from each other. The researchers are now trying to use the source to create a quantum computer based on "boson sampling". [11] With the help of a semiconductor quantum dot, physicists at the University of Basel have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream of identical photons. [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.

Dynamic programming is a technique that can yield relatively efficient solutions to computational problems in economics, genomic analysis, and other fields. But adapting it to computer chips with multiple "cores," or processing units, requires a level of programming expertise that few economists and biologists have. [16] Researchers at Lancaster University's Data Science Institute have developed a software system that can for the first time rapidly self-assemble into the most efficient form without needing humans to tell it what to do. [15] Physicists have shown that quantum effects have the potential to significantly improve a variety of interactive learning tasks in machine learning. [14] A Chinese team of physicists have trained a quantum computer to recognise handwritten characters, the first demonstration of " quantum artificial intelligence ". Physicists have long claimed that quantum computers have the potential to dramatically outperform the most powerful conventional processors. The secret sauce at work here is the strange quantum phenomenon of superposition, where a quantum object can exist in two states at the same time. [13] One of biology's biggest mysteries-how a sliced up flatworm can regenerate into new organisms-has been solved independently by a computer. The discovery marks the first time that a computer has come up with a new scientific theory without direct human help. [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. [10] Cambridge Quantum Computing Limited (CQCL) has built a new Fastest Operating System aimed at running the futuristic superfast quantum computers. [9] IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions. [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. The results have now been published in the "Physical Review Letters". [7] 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. 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.

A revolutionary and emerging class of energy-harvesting computer systems require neither a battery nor a power outlet to operate, instead operating by harvesting energy from their environment. [18]
In 1959 renowned physicist Richard Feynman, in his talk "Plenty of Room at the Bottom," spoke of a future in which tiny machines could perform huge feats. Like many forward-looking concepts, his molecule and atom-sized world remained for years in the realm of science fiction. [17]
The race towards quantum computing is heating up. Faster, brighter, more exacting – these are all terms that could be applied as much to the actual science as to the research effort going on in labs around the globe. [16]
For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum computers. [15]
The intricately sculpted device made by Paul Barclay and his team of physicists is so tiny it can only be seen under a microscope. But their diamond microdisk could lead to huge advances in computing, telecommunications, and other fields. [14]
Researchers from the Institute for Quantum Computing at the University of Waterloo and the National Research Council of Canada (NRC) have, for the first time, converted the color and bandwidth of ultrafast single photons using a room-temperature quantum memory in diamond. [13]
One promising approach for scalable quantum computing is to use an all-optical architecture, in which the qubits are represented by photons and manipulated by mirrors and beam splitters. So far, researchers have demonstrated this method, called Linear Optical Quantum Computing, on a very small scale by performing operations using just a few photons. In an attempt to scale up this method to larger numbers of photons, researchers in a new study have developed a way to fully integrate single-photon sources inside optical circuits, creating integrated quantum circuits that may allow for scalable optical quantum computation. [12]
Spin-momentum locking might be applied to spin photonics, which could hypothetically harness the spin of photons in devices and circuits. Whereas microchips use electrons to perform computations and process information, photons are limited primarily to communications, transmitting data over optical fiber. However, using the spin of light waves could make possible devices that integrate electrons and photons to perform logic and memory operations. [11]

In this paper, we propose an ad-hoc on-demand distance vector routing algorithm for mobile ad-hoc networks taking
into account node mobility. Changeable topology of such mobile ad-hoc networks provokes overhead messages in
order to search available routes and maintain found routes. The overheadmessages impede data delivery from sources
to destination and deteriorate network performance. To overcome such a challenge, our proposed algorithm estimates
link duration based neighboring node mobility and chooses the most reliable route. The proposed algorithm also
applies the estimate for route maintenance to lessen the number of overhead messages. Via simulations, the proposed
algorithmis verified in variousmobile environments. In the low mobility environment, by reducing routemaintenance
messages, the proposed algorithm significantly improves network performance such as packet data rate and end-toend
delay. In the high mobility environment, the reduction of route discovery message enhances network performance
since the proposed algorithm provides more reliable routes.

In business scenarios, where some of the data or the business attributes are neutrosophic, it may be useful to construct a warehouse that can support the analysis of neutrosophic data. In this paper, a neutrosophic data warehouse modelling approach is presented to support the neutrosophic analysis of the publishing house for books which allows integration of neutrosophic concept in dimensions and facts without affecting the core of a classical data warehouse. Also we describe a method is presented which includes guidelines that can be used to convert a classical data warehouse into a neutrosophic domain.

This paper fills in some blanks left between part 1 of this series, Kalman Folding (http://vixra.org/abs/1606.0328), and the rest of the papers in the series. In part 1, we present basic Kalman filtering as a functional fold, highlighting the advantages of this form for hardening code in a test environment. In that paper, we motivated the Kalman filter as a natural extension of the running average and variance, writing both as functional folds computed in constant memory. We expressed the running statistics as recurrence relations, where the new statistic is the old statistic plus a correction. We write the correction as a gain factor times some transform of a residual. The residual is the difference between the current (old) statistic and the incoming (new) observation. In both expressions, for brevity, we left derivations to the reader. Here, we present those derivations in full “school-level” detail, along with some basic explanation of the programming language that mechanizes the computations.

Based on creating generalized and hybrid set and library with neutrosophy and quad-stage method, this paper presents the concept of "computer information library clusters" (CILC). There are various ways and means to form CILC. For example, CILC can be considered as the "total-library", and consists of several "sub-libraries". As another example, in CILC, a "total-library" can be set up, and a number of "sub-libraries" are side by side with the "total-library". Specially, for CILC, the operation functions can be added; for example, according to "natural science computer information library clusters" (natural science CILC), and applying "variation principle of library (or sub-library)", “partial and temporary unified theory of natural science so far” with different degrees can be established. Referring to the concept of “natural science CILC”, the concepts of “social science CILC”, “natural science and social science CILC”, and the like, can be presented. While, referreing to the concept of “computer information library clusters”, the concepts of “computer and non-computer information library clusters”, “earth information library clusters”, “solar system information library clusters”, “Milky Way galaxy information library clusters”, “universe information library clusters”, and the like, can be presented.

Quicksort, invented by Tony Hoare in 1959, is one of the fastest sorting algorithms. However, conventional
implementations have some weak points, including the following: swaps to exchange two elements are redundant,
deep recursive calls may encounter stack overflow, and the case of repeated many elements in input data is a well-
known issue. This paper improves quicksort to make it more secure and faster using new or known ideas in C
language.

We address the topic of internet and communications integrity and continuity during times of social unrest and disturbance where a variety of actions can lead to short-term or long-term disruption of conventional, public and private internet and wireless networks. The internet disruptions connected with WikiLeaks in 2010, those in Egypt and Libya during protests and revolution commencing in January of 2011, and long-standing controls upon internet access and content imposed within China and other nations, are considered as specific and contemporary examples. We examine alternatives that have been proposed by which large numbers of individuals can maintain “connectivity without borders.” We review the strengths and weaknesses of such alternatives, the countermeasures that can be employed against such connectivity, and a number of innovative measures that can be used to overcome such countermeasures.

as a functional fold, highlighting the unique advantages of this form for
deploying test-hardened code verbatim in harsh, mission-critical environments.
In that paper, all examples folded over arrays in memory for convenience and
repeatability. That is an example of developing filters in a friendly
environment.
Here, we prototype a couple of less friendly environments and demonstrate
exactly the same Kalman accumulator function at work. These less friendly
environments are
- lazy streams, where new observations are computed on demand but never fully
realized in memory, thus not available for inspection in a debugger
- asynchronous observables, where new observations are delivered at arbitrary
times from an external source, thus not available for replay once consumed by
the filter

In this paper we develop the new physicalmathematical time scale kinetic approach-model applied
on organic and non-organic particles motion. Concretely,
here, at first, this new research approach is based on
enzyme particles dynamics results. At the beginning, a
time scale is defined to be an arbitrary closed subset of the
real numbers R, with the standard inherited topology.
Mathematical examples of time scales include real
numbers R, natural numbers N, integers Z, the Cantor set
(i.e. fractals), and any finite union of closed intervals of R.
Calculus on time scales (TSC) was established in 1988 by
Stefan Hilger. TSC, by construction, is used to describe the
complex process. This method may utilized for description
of physical (classical mechanics), material (crystal growth
kinetics, physical chemistry kinetics - for example,
kinetics of barium-titanate synthesis), (bio)chemical or
similar systems and represents major challenge for
contemporary scientists. In this sense, the MichaelisMenten (MM) mechanism is the one of the best known and
simplest nonlinear biochemical network which deserves
appropriate attention. Generally speaking, such processes
may be described of discrete time scale. Reasonably it
could be assumed that such a scenario is possible for MM
mechanism. In this work, discrete time MM kinetics
(dtMM) with time various step h, is investigated. Instead of
the first derivative by time used first backward difference
h. Physical basics for new time scale approach is a new
statistical thermodynamics, natural generalization of
Tsallis non-extensive or similar thermodynamics. A
reliable new algorithm of novel difference transformation
method, namely multi-step difference transformation
method (MSDETM) for solving system of nonlinear
ordinary difference equations is proposed. If h tends to
zero, MSDETM transformed into multi-step differential
transformation method (MSDTM). In the spirit of TSC,
MSDETM describes analogously MSDTM.

We exhibit a foldable Extended Kalman Filter that internally integrates
non-linear equations of motion with a nested fold of generic
integrators over lazy streams in constant memory.
Functional form allows us to switch integrators easily and to diagnose filter
divergence accurately, achieving orders of magnitude better speed than
the source example from the literature. As with all Kalman folds, we can move
the vetted code verbatim, without even recompilation, from the lab to the field.

In Kalman Folding 5: Non-Linear Models and the EKF, we present an
Extended Kalman Filter as a fold over a lazy stream of observations that uses a
nested fold over a lazy stream of states to integrate non-linear equations of
motion. In Kalman Folding 4: Streams and Observables, we present a
handful of stream operators, just enough to demonstrate Kalman folding over
observables.
In this paper, we enrich the collection of operators, adding takeUntil,
last, and map. We then show how to use them to integrate differential
equations in state-space form in two different ways and to generate test cases
for the non-linear EKF from paper 5.

deploying test-hardened code verbatim in harsh, mission-critical environments.
The examples in that paper are all static, meaning that the states of the model
do not depend on the independent variable, often physical time.
Here, we present mathematical derivations of the basic, static filter. These are
semi-formal sketches that leave many details to the reader, but highlight all
important points that must be rigorously proved. These derivations have several
novel arguments and we strive for much higher clarity and simplicity than is
found in most treatments of the topic.

Kalman filtering is commonplace in engineering, but less familiar to software
developers. It is the central tool for estimating states of a model, one
observation at a time. It runs fast in constant memory. It is the mainstay of
tracking and navigation, but it is equally applicable to econometrics,
recommendations, control: any application where we update models over time.
By writing a Kalman filter as a functional fold, we can test code in friendly
environments and then deploy identical code with confidence in unfriendly
environments. In friendly environments, data are deterministic, static, and
present in memory. In unfriendly, real-world environments,
data are unpredictable, dynamic, and arrive asynchronously.
The flexibility to deploy exactly the code that was tested is especially
important for numerical code like filters. Detecting, diagnosing and correcting
numerical issues without repeatable data sequences is impractical. Once code is
hardened, it can be critical to deploy exactly the same code, to the binary
level, in production, because of numerical brittleness. Functional form makes it
easy to test and deploy exactly the same code because it minimizes the coupling
between code and environment.

FPGAs and microprocessors are more similar than you may think. Here's a primer on how to program an FPGA and some reasons why you'd want to.
Small processors are, by far, the largest selling class of computers and form the basis of many embedded systems. The first single-chip microprocessors contained approximately 10,000 gates of logic and 10,000 bits of memory. Today, field programmable gate arrays (FPGAs) provide single chips approaching 10 million gates of logic and 10 million bits of memory...

FPGAs enable everyone to be a chip designer. This installment shows how to design the bus interface for a generic peripheral chip.
When designing with an embedded microprocessor, you always have to take into account, if not begin with, the actual pinout of the device. Each pin on a given microprocessor is uniquely defined by the manufacturer and must be used in a specific manner to achieve a specific function. Part of learning to design with embedded processors is learning the pin definitions. In contrast, field programmable gate array (FPGA) devices come to the design with pins completely undefined (except for power and ground). You have to define the FPGA's pins yourself. This gives you incredible flexibility but also forces you to think through the use of each pin...

In many web applications, a recommendation is not a single item sug- gested to a user but a list of possibly interesting contents that may be ranked in some contexts. The combinatorial bandit problem has been studied quite extensively these last two years and many theoretical re- sults now exist : lower bounds on the regret or asymptotically optimal algorithms. However, because of the variety of situations that can be considered, results are designed to solve the problem for a specific reward structure such as the Cascade Model. The present work focuses on the problem of ranking items when the user is allowed to click on several items while scanning the list from top to bottom.

We discuss the problem of finding an optimum linear seating arrangement for a small social network, i.e. approaching the problem put forth in XKCD comic 173 – for a small social network, how can one determine the seating order in a row (e.g at the cinema) that corresponds to maximum enjoyment? We begin by improving the graphical notation of the network, and then propose a method through which the total enjoyment for a particular seating arrangement can be quantified. We then discuss genetic programming, and implement a first-principles genetic algorithm in python, in order to find an optimal arrangement. While the method did produce acceptable results, outputting an optimal arrangement for the XKCD network, it was noted that genetic algorithms may not be the best way to find such an arrangement. The results of this investigation may have tangible applications in the organising of social functions such as weddings.

Group decision makers making process - an analytic hierarchy approach
The paper deals with a step-wise analytic hierarchy process (AHP) applied by a
group of decision makers wherein nobody has a dominant position and it is unlikely to
come to terms with respect to either the weights of different objectives or expected utilities
of different alternatives. One of the AHP outcomes, that is the consistency index is
computed for each decision maker, for all other decision makers but that one, and for the
whole group. Doing so, the group is able to assess to which extent each decision maker
alters the group consistency index and a better consistency index could be achieved if the
assessment procedure is being resumed by the most influential decision maker in terms of
consistency.
The main contribution of the new approach is the algorithm presented in as a flow
chart where the condition to stop the process might be either a threshold value for the
consistency index, or a given number of iterations for the group or decision maker,
depending on the degree to which the targeted goal has been decomposed into conflictual
objectives.

In this paper we present texture features for images embedded in the neutrosophic domain. The aim is to extract a set of features to represent the content of each image in the training database to be used for the purpose of retrieving images from the database similar to the image under consideration.

One of the most important aspects that influences the performance of
parallel applications is the speed of communication between their tasks. To optimize communication, tasks that exchange lots of data should be mapped to processing units that have a high network performance. This technique is called communication-aware task mapping and requires detailed information about the underlying network topology for an accurate mapping. Previous work on task mapping focuses on network clusters or shared memory architectures, in which the topology can be determined directly from the hardware environment. Cloud computing adds significant challenges to task mapping, since information about network topologies is not available to end users. Furthermore, the communication performance might change due to external factors, such as different usage patterns of other users. In this paper, we present a novel solution to perform communication-
aware task mapping in the context of commercial cloud environments with multiple instances. Our proposal consists of a short profiling phase to discover the network topology and speed between cloud instances. The profiling can be executed before each application start as it causes only a negligible overhead. This information is then used together with the communication pattern of the parallel application to group tasks based on the amount of communication and to map groups with a lot of communication between them to cloud instances with a high network performance. In this way, application performance is increased, and data traffic between instances is reduced. We evaluated our proposal in a public cloud with a variety of MPI-based parallel benchmarks from the HPC domain, as well as a large scientific application. In the experiments, we observed substantial performance improvements (up to 11 times faster) compared to the default scheduling policies.

Is proved that P ≠ NP, showing 2 problems that are executed in constant complexity time O(1) in a nondeterministic algorithm, but in exponential complexity time related to the length of the input (input size) in a deterministic algorithm. These algorithms are essentially simple, so they can not have a significant reduction in its complexity, what could cause the proofs shown here to become invalid.

Modular programming is a very efficient way of system creation. By reducing the number of relevant relations the method diminishes the complexity of configuring and supporting modular systems. The method uses the available resources in an optimal way.
The current way of software generation uses an object oriented way of system construction that does not encapsulate the objects, such that their internals are effectively hidden and guarded against obstructive access by external objects. This paper introduces a new way of notation that enforces this encapsulation. Many programming languages already implement part of the required methodology. An example is the razor language. This paper extends these ideas to a modular way of programming.
The approach makes from every relational database a modular database and from every file system a modular file system. It makes from every communication service a modular communication service and it standardizes programming such that reuse can be optimized in a global way. It will improve the robustness and reliability of software and enables to a large extent automated system configuration.

We outline here the design considerations and implementation of woodcoin, in particular those
which separate it from other cryptocurrencies. Woodcoin is a cryptocurrency very much like
bitcoin. However the design of bitcoin explicitly models a non-renewable resource: gold. For woodcoin we more closely model a sustainable resource. In particular woodcoin avoids the time asymmetries of the bitcoin release model, maximizing the incentive to participate and the longevity of the coin at the same time. Our solution is logarithmic growth of the money supply. In addition, we outline the design considerations behind two other changes to the core protocol: mining with the Skein hash function and securing digital ownership with the X9_prime256v1 curve using ECDSA.

A new kind of dynamics for simulations based upon quantum-classical hybrid is discussed. The model is represented by a modified Madelung equation in which the quantum potential is replaced by different, specially chosen potentials. As a result, the dynamics attains both quantum and classical properties: it preserves superposition and entanglement of random solutions, while allowing one to measure its state variables using classical methods. Such an optimal combination of characteristics is a perfect match for quantum- inspired information processing. In this paper, the retrieval of stored items from an exponentially large unsorted database is performed by quantum-inspired resonance using polynomial resources due to quantum-like superposition effect.

Data mining, the extraction of hidden predictive information from large databases, is nothing but
discovering hidden value in the data warehouse. Because of the increasing ability to trace and collect large
amount of personal information, privacy preserving in data mining applications has become an important
concern. Data distortion is one of the well known techniques for privacy preserving data mining. The objective
of these data perturbation techniques is to distort the individual data values while preserving the underlying
statistical distribution properties. These techniques are usually assessed in terms of both their privacy
parameters as well as its associated utility measure. In this paper, we are studying the use of non-negative
matrix factorization (NMF) with sparseness constraints for data distortion.

considerable research effort is devoted to investigations of interactions between
antennas on handsets and the human body. This interaction significantly
changes the antenna characteristics from that in free space or even on the device
(handset, laptop). In this paper and in order to study this problem, firstly a
planar inverted-F antenna (PIFA) was designed and simulated to operate over
the frequency 2,45 GHz , then the influence of the human head on the return
loss and on the radiation efficiency of the antenna has been studied.

Ad hoc networks are infrastructure-less collection of mobile nodes,
characterized by wireless links, dynamic topology and ease of deployment. Proactive
routing protocols maintain the network topology information in the form of routing
Tables, by periodically exchanging the routing information. Mobility of nodes leads to
frequent link breaks, resulting in loss of communication and thus the Information in the
Table may become stale after some time. DSDV routing protocol follows proactive
approach for routing and uses stale routes in case of link break, which is the major cause
of its low performance as mobility increases. We have focused on two variants of DSDV
namely Eff-DSDV and I-DSDV, which deals with the broken link reconstruction and
discussed in these protocols, the process of route reconstruction due to broken links. To
analyze this route reconstruction mechanism, we have used a terrain of size 700m × 800
m with 8 nodes placed randomly. Analysis shows that both Eff-DSDV & I-DSDV,
perform better than DSDV in Packet Delivery Ratio and Packet Loss with slight increase
in Routing Overheads.

Educational data mining is an emerging technology concerned with developing methods for exploring the various
unique data that exists in the educational settings and uses them to understand the students as well as the domain in which they
learn. Educational domain consists of a lot of data related to students, teachers and other learning strategies. Classification
algorithms can be used on various educational data to mine the academic records. It can be used to predict student‘s outcome
based on their previous academic performance. The various predictive algorithms like, C4.5, Random tree are applied on
student‘s previous academic results to predict the outcome of the students in the university examination. The prediction would
help the tutor in understanding the progress and attitude of the student towards the studies. It would also help them to identify the
students who are constantly improving in their studies and help them to achieve a higher percentage. It also helps them to identify
the underperformers so that extra effort can be taken to achieve a better result. The algorithms are analyzed based on their
accuracy of predicting the result, the recall and the precision values. The accuracy of the algorithm is predicted by comparing the
output generated by the algorithm with the original result obtained by the students in the university examination.

Ultra wideband (UWB) technology is one of the promising solutions for future short-range
communication which has recently received a great attention by many researchers. However,
interest in UWB devices prior to 2001 was primarily limited to radar systems, mainly for
military applications due to bandwidth resources becoming increasingly scarce and also its
interference with other commutation networks. This research work provides performance
analysis of multiband orthogonal frequency division multiplexing (MB-OFDM) UWB MIMO
system in the presence of binary phase-shift keying time-hopping (BPSK-TH) UWB or BPSKDS
UWB interfering transmissions under Nakagami-m and Lognormal fading channels
employing various modulation schemes using MATLAB simulations. The research work
indicates that it is totally impossible to predict the performance of UWB system in
Lognormal channel.

A Chaos based embedding process for textual data offering high capacity and high security simultaneously is designed and implemented. A chaotic image, obtained using a frequency dependant driven chaotic system is used as the data carrier in which textual data is embedded. The decryption and subsequent performance analyses reveal a high fidelity with a mean square error of around 0.0009 percent and a compression ratio increasing nonlinearly with text size, with ratio values more than 150:1 obtained for significantly large texts. Moreover, a very high level of security leading to up to 60 percent of mean square error values even for 1 percent misalignment in the decryption process is observed. The extreme simplicity of implementation coupled with the twin advantages of high compression ratios and high security forms the highlight of the present work.

Efficient techniques of Genome Data handling and storage are the need of the hour in the present genetic engineering era. The present work purports to the design and implementation of a Genome Sequence Data Compression Technique without the use of references and lookup. This is achieved by first generating a digital chaotic bit stream, formed by performing XOR operations on three square waves with mismatched frequencies. The generated bit stream is XORed with the Genome Sequence bit stream after necessary data conditioning, and the result is stored as a 2D array (image). The png format is chosen, owing to its inherent lossless properties. It is seen that the perfectly reversible operations of compression and decompression result in compression ratios of around 2.6-3.5 being achieved with absolute zero error. The use of digital chaos provides an additional layer of security, since the frequencies of the input square wave signals form a secure key, which when mismatched during decompression even by 1 percent, can result in error rates of upto 60 percent.

A Chaos based compression technique offering high capacity and high security simultaneously is designed and implemented. A chaotic image, obtained by reshaping the signal representing a frequency dependant driven chaotic system is used as the data carrier in which data from the file to be compressed is embedded. Implementation of the algorithm is carried out in MATLAB and Python platforms for various filetypes such as txt, png, pdf, mp3, 3gp and rar formats. A comparative performance analysis reveals a high fidelity with a mean square errors of less than 0.0009 percent as well as a relatively high compression ratio value of 5-6. A very high level of security leading to up to 60 percent of mean square error values even for 1 percent misalignment in the decryption process is observed. The execution times for the implementations are obtained reasonably at around 5 seconds. A new compression technique, termed ‘supercompression’ consisting of repeated application of the compression technique is proposed. A proof-of-concept implementation achieved extremely high compression ratios of around 40000. The extreme simplicity of implementation coupled with the twin advantages of high compression ratios and high security forms the highlight of the present work.

The current era of data explosion entails the necessity of high efficiency in terms of data capacity and data security. This scenario of Big Data inevitably leads to the technology of Internet of Things (IoT) in the future.
The present project purports to the effective harnessing of nonlinear signal processing principles leading to enhanced security of data without compromising on capacity. The advantage of using nonlinear signal processing lies in the fact that the nonlinearity of a single NMOS transistor is able to provide robust security by generation of chaotic signals. This results in low power dissipation and simplicity of circuitry. The enhanced secure communication techniques are then studied giving importance to the phase variations in the signal and are then applied to real world information systems. Also, the possibility of introducing such techniques in conventional big data systems such as RDBMS and Hadoop are considered.
After significantly demonstrating the capabilities of the nonlinear signal processing approach in terms of fidelity, capacity and robustness, the techniques are extended even further to include an Internet of Things (IoT) based environment. The implementation of nonlinear signal processing techniques to IoT based systems such as RFID are explored. At the final stage, the change in the managerial perspective required to handle the IoT dominated environment is discussed. The business level implications of such a technology shift are studied. This study of IoT is termed as “Management of Things” (MoT).
The principal aim of this project is to provide a feasible, efficient, innovative yet costeffective solution to the biggest problems of the telecommunication world today – data capacity and data security. This project thus follows from the motto “Transformation through Information” and leads us gently to become effective citizens of a smarter planet.

The number of methods available for classification of multi-label data has increased rapidly over recent years, yet relatively few links have been made with the related task of classification of sequential data. If labels indices are considered as time indices, the problems can often be seen as equivalent. In this paper we detect and elaborate on connections between multi-label methods and Markovian models, and study the suitability of multi-label methods for prediction in sequential data. From this study we draw upon the most suitable techniques from the area and develop two novel competitive approaches which can be applied to either kind of data. We carry out an empirical evaluation investigating performance on real-world
sequential-prediction tasks: electricity demand, and route prediction. As well as showing that several popular multi-label algorithms are in fact easily applicable to sequencing tasks, our novel approaches, which benefit from a unified view of these
areas, prove very competitive against established methods.

We introduce two new Kirchhoff-law–Johnson-noise (KLJN) secure key distribution schemes, which are the generalization of the original KLJN version. The first system, the Random-Resistor (RR-) KLJN scheme is using random resistors chosen from a quasi-continuum set of resistance values. It is well known since the creation of the KLJN concept that such system could work because Alice and Bob can calculate the unknown resistance value from measurements; however, it has not been addressed in publications as it was considered impractical. The reason for discussing it is the second scheme, the Random-Resistor-Random-Temperature (RRRT-) KLJN key exchanger inspired by a recent paper of Vadai-Mingesz-Gingl where security was maintained at non-zero power flow. In the RRRT-KLJN secure key exchanger scheme, both the resistances and their temperatures are continuum random variables. We prove that the security of the RRRT-KLJN system can be maintained at non-zero power flow thus the physical law guaranteeing the security is not the Second Law of Thermodynamics but the Fluctuation-Dissipation Theorem. Knowing their own resistance and temperature values, Alice and Bob can calculate the resistance and temperature values at the other end from the measured voltage, current and power-flow data in the wire. Eve cannot determine these values because, for her, there are 4 unknown quantities, while she can set up only 3 equations. The RRRT-KLJN scheme has several advantages and makes all the existing former attacks invalid or incomplete.

Using Personalized Web Search (PWS) we can improve the quality of search results in the Internet. The existing UPS based Personalized Web Searching has many drawbacks. First, there may be a chance of eavesdropping when generalized profile forwarded to the server. Second, web server is vulnerable to web attacks like URL manipulation attacks. The impact of these attacks will affect user’s personal information. So we introduce a new framework called UPES. Here, the data stored in the server-side and request from user will be in encrypted form. Fully Homomorphic Encryption over Integers (FHEI) is used for encrypting data. The experimental results show that this framework functioned in the best possible manner with the least waste of time and effort.

Al Quran is the Muslim holy book written in Arabic. To read the Quran recitation necessary knowledge of the guidelines. In the context of everyday people find difficulty in recitation of the Quran. Therefore, the detection system tajwid needed to help users find the recitation of the Quran. In this study, the method of Bray Curtis Distance is used to detect the image of the Holy Qur'an recitation. The test results show that the accuracy of the system is 60% to 90%. The percentage of detection rate shows that the method can be used Bray curtis as one approach to detection at the image of the Holy Qur'an recitation. This system has several drawbacks that have a high false positive rate, or an error about a 40% chance. To improve the performance of this recitation detection system, can be done by providing further training with additional training data more and more varied. However, this recitation detection system does not deny the importance of teachers in learning how to read in accordance with the rules of recitation is right.

Multi-dimensional classification (also known variously as multi-target, multi-objective, and multi-output classification) is the supervised learning problem where an instance is associated to qualitative discrete variables (a.k.a. labels), rather than with a single class, as in traditional classification problems. Since these classes are often strongly correlated, modeling the dependencies between them allows MDC methods to improve their performance -- at the expense of an increased computational cost.
A popular method for multi-label classification is the classifier chains (CC), in which the predictions of individual classifiers are cascaded along a chain, thus taking into account inter-label dependencies. Different variant of CC methods have been introduced, and many of them perform very competitively across a wide range of benchmark datasets. However, scalability limitations become apparent on larger datasets when modeling a fully-cascaded chain. In this work, we present an alternative model structure among the labels, such that the Bayesian optimal inference is then computationally feasible. The inference is efficiently performed using a Viterbi-type algorithm.
As an additional contribution to the literature we analyze the relative advantages and interaction of three aspects of classifier chain design with regard to predictive performance versus efficiency: finding a good chain structure vs.a random structure, carrying out complete inference vs. approximate or greedy inference, and a linear vs. non-linear base classifier. We show that our Viterbi CC can perform best on a range of real-world datasets.

IF THE ELEMENT WHICH WE WANT TO SEARCH IS AT ANY POSITION BEFORE N/2 THAN MY-SEARCH AND LINEAR-SEARCH BOTH WILL HAVE EXECUTION TIME , BUT THE MAGIC HAAPENS WHEN THE SEARCH ELEMENT IS AFTER N/2 POSITION.SUPPOSE THE ELEMENT WANT TO SEARCH IS AT Nth POSITION, THEN USING THE LINEAR SEARCH WILL FIND THE ELEMENT AFTER Nth ITERATION,BUT USING MY-SEARCH WE CAN SEARCH THE ELEMENT AFTER 1st ITERATION ITESELF.
WHEN WE ARE DEALING WITH A SITUTATION WHEN SIZE IS SOMETHING 10 OR 15 ITS OK. BUT CAN YOU IMAGINE THE CASE WHEN THE SIZE IS “100000000” OR EQUIVALANENT.IF WE USE THIS LINEAR SEARCH TECHINIUQE THAN THE TOTAL EXPENDITURE YOU CAN THINK OFF TO CONTINUE THE LOOP FOR 100000000 TIMES.BUT RATHER IF USE MY-SEARCH U GET THE DESIRED SEARCH JUST AFTER 1 ITERATIONS.

I show here the biggest reasons the two vulnerability analyses were flawed. The attacks appear to hinder other miners who are competitors. However, both of the attacks harm the attacker's bottom line more than any harm to the competitors can emerge as profits for the attacker.

In this paper we discuss some novel algorithms for linear programming inspired by geometrical considerations and use simple mathematics related to finding intersections of lines and planes. All these algorithms have a common aim: they all try to approach closer and closer to “centroid” or some “centrally located interior point” for speeding up the process of reaching an optimal solution! Imagine the “line” parallel to vector C, where CTx denotes the objective function to be optimized, and further suppose that this “line” is also passing through the “point” representing optimal solution. The new algorithms that we propose in this paper essentially try to reach at some feasible interior point which is in the close vicinity of this “line”, in successive steps. When one will be able to arrive finally at a point belonging to small neighborhood of some point on this “line” then by moving from this point parallel to vector C one can reach to the point belonging to the sufficiently small neighborhood of the “point” representing optimal solution.

Instruction sequences play a key role in computing and have the
potential of becoming more important in the conceptual development of
informatics in addition to their existing role in computer technology and machine architectures. After 15 years of development of instruction sequence theory a more robust and outreaching terminology is needed for it which may support further development. Instruction sequencing is the central concept around which a new family of terms and phrases is developed.

We discuss the P versus NP problem from the perspective of
addition operation about polynomial functions. Two contradictory propositions for the addition operation are presented.
With the proposition that the sum of k (k<=n)
polynomial functions on n always yields a polynomial function, we
prove that P=NP, considering the maximum clique problem. However,
we also get a contradiction if we accept the proposition. So, we
conclude that the sum of k polynomial functions may yield a
exponential function. Accepting this proposition, we prove that
P!=NP by constructing an abstract decision problem.

The Calogero type matrix discretization scheme is applied to constructing the Lax type integrable discretizations of one wide enough class of nonlinear integrable dynamical systems on functional manifolds. Their Lie-algebraic structure and complete integrability related with co-adjoint orbits on the Markov co-algebras is discussed. It is shown that a set of conservation laws and the associated Poisson structure ensue as a byproduct of the approach devised. Based on the Lie algebras quasi-representation property the limiting procedure of finding the nonlinear dynamical systems on the corresponding functional spaces is demonstrated.

This article demonstrates a general solution for the problems of class (P vs.NP). Peculiarly for the problems of class (P=NP). Presented solution is quite simple and can be applicable in many various areas of science. At general, (P=NP) it’s a class of problems which possess algorithmic nature. The algorithms should contains one or more of logical operations like (if...then) instruction, or Boolean operations. The proper proof for this thesis with a new formula was presented. Except formula, one proper example was presented for the problem (P=NP). Exists a lot of problems for which P class problems are equivalent with the NP problems (P=NP). Millions, I think.
For example, I discovered extremely effective algorithm for the “Hamiltonian Path Problem”. Algorithm can find the proper solution for 100 cities at very short time. Solution time for old laptop is less than two seconds. Classical solution for that problem exists, but is extremely difficult and computer’s time is huge. Algorithm for the Hamilton problem, will be presented at separate article (needs more paper).

Cloud computing is continuously growing as a
business model for hosting information and communication technology
applications. Although on-demand resource consumption
and faster deployment time make this model appealing for
the enterprise, other concerns arise regarding the quality of
service offered by the cloud. One major concern is the high
availability of applications hosted in the cloud. This paper
demonstrates the tremendous effect that the placement strategy
for virtual machines hosting applications has on the high
availability of the services provided by these applications. In
addition, a novel scheduling technique is presented that takes
into consideration the interdependencies between applications
components and other constraints such as communication delay
tolerance and resource utilization. The problem is formulated
as a linear programming multi-constraint optimization model.
The evaluation results demonstrate that the proposed solution
improves the availability of the scheduled components compared
to OpenStack Nova scheduler.

After briefly summarizing our general theoretical arguments, we show that, the experienced strong information leak at the Gunn-Allison-Abbott attack [Scientific Reports 4 (2014) 6461] against the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange scheme, resulted from a serious design flaw of the system. The attenuator broke the single Kirchhoff-loop into two coupled loops. This is an illegal operation because the single loop is essential for the security, thus the observed leak is obvious. We demonstrate this by cracking the system with an elementary current comparison attack yielding close to 1 success probability for Eve even without averaging within a sub-correlation-time measurement window. A fully defended KLJN system would not be able to function, at all, due to its built-in current-comparison defense against active (invasive) attacks.

In this paper, I investigate a prefix-free universal Turing machine (UTM) running multiple programs in parallel according to a scheduler. I found that if, over the course of the computation, the scheduler adjusts the work done on programs so as to maximize the entropy in the calculation of the halting probability Omega, the system will follow many laws analogous to the laws of physics. As the scheduler maximizes entropy, the result relies on algorithmic thermodynamics which connects the halting probability of a prefix-free UTM to the Gibb's ensemble of statistical physics (which also maximizes entropy). My goal with this paper is to show specifically, that special relativity and general relativity can be derived from algorithmic thermodynamics under a certain choice of thermodynamic observables applied to the halting probability.

The bordering method of the Cholesky decomposition is backward differentiated to derive a method of calculating first derivatives. The result is backward differentiated again and an algorithm for calculating second derivatives results. Applying backward differentiation twice also generates an algorithm for conducting forward differentiation. The differentiation methods utilize three main modules: a generalization of forward substitution for calculating the forward derivatives; a generalization of backward substitution for calculating the backward derivatives; and an additional module involved with the calculation of second derivatives. Separating the methods into three modules lends itself to optimization where software can be developed for special cases that are suitable for sparse matrix manipulation, vector processing and/or blocking strategies that utilize matrix partitions. Surprisingly, the same derivative algorithms fashioned for the Cholesky decomposition of a positive definite matrix can be used again for matrices that are indefinite. The only differences are very minor adjustments involving an initialization step that leads into backward differentiation and a finalization step that follows forward differentiation.

We utilize a previously reported methodological framework [5], to find a general set of mappings for any satisfiability (SAT) problem to a set of arithmetized codes allowing a classification hierarchy enumerable via integer partition functions. This reveals a unique unsatisfiability criterion via the introduction of certain universal indicator functions associating the validity of any such problem with a mapping between Mersenne integers and their complements in an inclusive hierarchy of exponential intervals. Lastly, we present means to reduce the complexity of the original problem to that of a special set of binary sequences and their bit block analysis via a reduction of any expression to a type of a Sequential Dynamical System (SDS) using the technique of clause equalization. We specifically notice the apparent analogy of certain dynamical properties behind such problems with resonances and coherencies of multi-periodic systems leading to the possibility of certain fast analog or natural implementations of dedicated SAT-machines. A Matlab toolbox is also offered as additional aid in exploring certain simple examples.

This paper describes the backward differentiation of the Cholesky decomposition by the bordering method. The backward differentiation of the Cholesky decomposition by the inner product form and the outer product form have been described elsewhere. It is found that the resulting algorithm can be adapted to vector processing, as is also true of the algorithms developed from the inner product form and outer product form. The three approaches can also be fashioned to treat sparse matrices, but this is done by enforcing the same sparse structure found for the Cholesky decomposition on a secondary work space.

We propose developing an XML-based system to enhance scientific papers and articles. A system whereby the premises of arguments are made explicit in XML tags. These tags provide a link between papers to more clearly exhibit deductive knowledge dependencies. The tags allow us to construct deductive networks which are a visual representation of deductive knowledge dependencies. A deductive network (DN) is a kind of bayesian network, but without probabilities.

In this paper, we explore the connections between graphs and Turing machines. A method to construct Turing machines from a general undirected graph is provided. Determining whether a Hamiltonian cycle does exist is now shown to be equivalent to solving the halting problem. A modified version of Turing machines is now developed to solve certain classes of computational problems.

Quicksort, invented by Tony Hoare in 1959, is one of the fastest sorting algorithms. However, conventional
implementations have some weak points, including the following: swaps to exchange two elements are redundant,
deep recursive calls may encounter stack overflow, and the case of repeated many elements in input data is a well-
known issue. This paper improves quicksort to make it more secure and faster using new or known ideas in C
language.

In Kalman Folding, Part 1, we present basic, static Kalman filtering
as a functional fold, highlighting the unique advantages of this form for
deploying test-hardened code verbatim in harsh, mission-critical environments.
The examples in that paper are all static, meaning that the states of the model
do not depend on the independent variable, often physical time.
Here, we present mathematical derivations of the basic, static filter. These are
semi-formal sketches that leave many details to the reader, but highlight all
important points that must be rigorously proved. These derivations have several
novel arguments and we strive for much higher clarity and simplicity than is
found in most treatments of the topic.

In Kalman Folding, Part 1, we present basic, static Kalman filtering as a functional fold, highlighting the unique advantages of this form for deploying test-hardened code verbatim in harsh, mission-critical environments. The examples in that paper are all static, meaning that the states of the model do not depend on the independent variable, often physical time. Here, we present a dynamic Kalman filter in the same, functional form. This filter can handle many dynamic, time-evolving applications including some tracking and navigation problems, and is easilly extended to nonlinear and non-Gaussian forms, the Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) respectively. Those are subjects of other papers in this Kalman-folding series. Here, we reproduce a tracking example from a well known reference, but in functional form, highlighting the advantages of that form.

Os algoritmos são essencialmente simples para que tenham ainda alguma redução significativa em sua complexidade, o que poderia invalidar as provas aqui apresentadas.

Computer Engineering requires you to know a vast array of programming languages, as well as utilizing different technologies in order to design hardware, or manage databases. It can often be identified as the cross between Information Technology and Electrical Engineering. What I learned is that you don’t have to only know C and C++, but you will also be required to learn more, especially working into the Hardware, Software, and Database side. Softwares you need to be familiar with include Visual Studio, and sometimes Open Source technologies. All in all I learned a great deal of knowledge from the people in which I talked to. I learned that Computer Engineering and related fields, have an impact on technological advancements, as well as making the world an easier place to live. I learned the overall power of different subjects in the fields such as utilizing UML language, Blockchain Technology, Javascript, Python, and the power of Linux. Some of these, I may present in throughout this paper. The purpose to this paper is to inform the average user about what is in the field, what Computer Engineers do, as well as the powerful research and impact of the field. By the end of this paper, I hope you have a beginner’s expertise on the implications of this widely known field.

The number of methods available for classification of multi-label data has increased rapidly over recent years, yet relatively few links have been made with the related task of classification of sequential data. If labels indices are considered as time indices, the problems can often be seen as equivalent. In this paper we detect and elaborate on connections between multi-label methods and Markovian models, and study the suitability of multi-label methods for prediction in sequential data. From this study we draw upon the most suitable techniques from the area and develop two novel competitive approaches which can be applied to either kind of data. We carry out an empirical evaluation investigating performance on real-world sequential-prediction tasks: electricity demand, and route prediction. As well as showing that several popular multi-label algorithms are in fact easily applicable to sequencing tasks, our novel approaches, which benefit from a unified view of these areas, prove very competitive against established methods.

We introduce two new Kirchhoff-law–Johnson-noise (KLJN) secure key distribution schemes which are generalizations of the original KLJN scheme. The first of these, the Random-Resistor (RR–) KLJN scheme, uses random resistors with values chosen from a quasi-continuum set. It is well-known since the creation of the KLJN concept that such a system could work in cryptography, because Alice and Bob can calculate the unknown resistance value from measurements, but the RR–KLJN system has not been addressed in prior publications since it was considered impractical. The reason for discussing it now is the second scheme, the Random-Resistor–Random-Temperature (RRRT–) KLJN key exchange, inspired by a recent paper of Vadai, Mingesz and Gingl, wherein security was shown to be maintained at non-zero power flow. In the RRRT–KLJN secure key exchange scheme, both the resistances and their temperatures are continuum random variables. We prove that the security of the RRRT–KLJN scheme can prevail at non-zero power flow, and thus the physical law guaranteeing security is not the Second Law of Thermodynamics but the Fluctuation–Dissipation Theorem. Alice and Bob know their own resistances and temperatures and can calculate the resistance and temperature values at the other end of the communication channel from measured voltage, current and power-flow data in the wire. However, Eve cannot determine these values because, for her, there are four unknown quantities while she can set up only three equations. The RRRT–KLJN scheme has several advantages and makes all former attacks on the KLJN scheme invalid or incomplete.

About a year after Ittay Eyal published two papers claiming vulnerabilities in the bitcoin mining protocol, we have seen that the network is still strong (it has grown in hashpower many times over) and is unaffected by the supposed problems. I show here the biggest reasons the two vulnerability analyses were flawed. The attacks appear to hinder other miners who are competitors. However, both of the attacks harm the attacker's bottom line more than any harm to the competitors can emerge as profits for the attacker.

We discuss the P versus NP problem from the perspective of addition operation about polynomial functions. Two contradictory propositions for the addition operation are presented. With the proposition that the sum of k (k<=n+1) polynomial functions on n always yields a polynomial function, we prove that P=NP, considering the maximum clique problem. And with the proposition that the sum of k polynomial functions may yield an exponential function, we prove that P!=NP by constructing an abstract decision problem. Furthermore, we conclude that P=NP and P!=NP if and only if the above propositions hold, respectively.

A recent paper by Gunn–Allison–Abbott (GAA) [L.J. Gunn et al., Scientific Reports 4 (2014) 6461] argued that the Kirchhoff-law–Johnson-noise (KLJN) secure key exchange system could experience a severe information leak. Here we refute their results and demonstrate that GAA’s arguments ensue from a serious design flaw in their system. Specifically, an attenuator broke the single Kirchhoff-loop into two coupled loops, which is an incorrect operation since the single loop is essential for the security in the KLJN system, and hence GAA’s asserted information leak is trivial. Another consequence is that a fully defended KLJN system would not be able to function due to its built-in current-comparison defense against active (invasive) attacks. In this paper we crack GAA’s scheme via an elementary current comparison attack which yields negligible error probability for Eve even without averaging over the correlation time of the noise.
