Error commission, detection, and correction are the products of the activities of a complex neural network referred to the error monitoring and processing system (EMPS) diffusely located in different brain regions. High-precision error coupling is the hallmark of EMPS functioning that is the result of effective neural processing and monitoring of error signals. Error commission, detection and correction as generic entities of the neural network of EMPS are influenced by some factors classified under two broad categories: endogenous and endogenous. We had previously reported the effect of exogenous and endogenous alcohol as well as other factors that may affect this system. It is imperative to note that cells regulating the activities of the brain (including regions responsible for EMPS) rely mainly on the metabolic substrate "glucose" to ensure adequate functioning. More importantly, it is not just the availability of glucose that ensures adequate functioning of neurons, but the process by which glycemia stabilization is achieved through the balancing of glucose consumption rate and release into the blood stream under a variety of physiological stressors (cognitive or mental workload e.g. mental work executed by participants in an experimental conditions over a period 4-6 hours on fasting) to maintain the "set point". This process that is referred to glycemic allostasis involves the utilization of glucose molecules to maintain the anatomo-physiological integrity of cells comprising the neural network of EMPS. Unfortunately, little attention has been given to the allostatic regulation of glycemia that is necessary to ensure adequate functioning and provide high precision error coupling in the EMPS. In this paper, we produced a model system of error commission, detection, and correction and examine the possible effects and mechanisms of glycemic allostasis regulation on error coupling in the EMPS.

Digital signatures are important primitives for building secure systems and are widely used in internet and electronic commerce for authencation. The most famous digital signature schemes are based on either the intractability of the integer factorization problem or the discrete logarithmic problem over finite fields. With Shor's algorithm on a quantum computer, these problems become tractable. Hence developments of signature schemes which are not based on these problems are crucial for maintaining information security. This paper introduces the conjugate twisted root extraction problem, and proposes a digital signature scheme based on a group of 2 × 2 matrices over N-truncated one variable polynomials. Its security relies on the cojugate twisted e-th root extraction problem. We prove that an adversary cannot forge a signature on a document unless the adversary extracts the e-th root in this group. The performance and other security issues are also discussed.

Grid connected photovoltaic plants for residential applications are normally designed through deterministic methods on the basis of system requirements as: PV array peak power, available budget, or available space. Unfortunately, these approaches give only suboptimal results. More effective design techniques are those oriented to fulfill given performance targets as minimum pay-back time, minimum life cycle cost, or minimum annual electrical energy cost. However, they require very complex optimization techniques, especially if the plant encompasses energy storage systems. An analytic approach is presented in this paper to optimally sizing the photovoltaic module array and the energy storage system in a grid-connected generator serving a set of residential loads, on the basis of annual average solar radiation data and load demand. The configuration with the shorter pay-back time is identified through a mathematical model, describing the variation of the annual energy cost as a function of the plant configuration. The proposed method can be easily modified to take into account different optimization targets, as maximum life-cycle profit.

Synchronization characteristic of periodic oscillators are based on the extraction of a special variable, phase. The subject of this phenomenon is considered as very important issue in a wide field of sciences. However, until now the research of the synchronization phenomena depends on big data set applications and the condition that this measuring needs the data sets to have same period. In this paper, we develop a new novel approach of the synchronization measuring of small data set using a new technique in which we create a procedure of stable period for each for investigation sequence of small data set. This study based on experimental results. Our future plan is to continue our work in order to found it with mathematical models. Furthermore, we would like to apply our method in other scientific fields.

We construct a stochastic model of real estate pricing. The method of the pricing construction is based on a sequential comparison of supply prices. We prove that under standard assumptions imposed upon the comparison coefficients there exists a unique non-degenerate limit in distribution and this limit has a Log Normal law of distribution. We verify agreement between empirical distributions of prices and theoretically obtained Log Normal distribution by numerous statistical data of real estate prices from Saint-Petersburg (Russia). To establish this accordance we essentially apply the efficient and sensitive test of fit of Kolmogorov-Smirnov. Basing on the world admitted standard of estimation prices in real estate market, we conclude that the most probable price, i.e. mode of distribution, is correctly and uniquely determined under the Log Normal approximation. Since the mean value of a Log Normal distribution exceeds the mode -- most probable value, it follows that the prices valued by the mathematical expectation are systematically overstated.

Recent years have witnessed a growing-number of plagiarism in the IT circle with the fast-developing Internet technology and an industry of software piracy is also simmering beneath the surface. There is no doubt that the plagiarists' behaviors belong to intellectual property infringement. So bad is the consequence that the plagiarism identification is drawing more and more attention from the public nowadays. Based on the longest common subsequence seeking algorithm, this paper develops a dynamic programming to solve the duplicate code checking problem and puts forward a new method to measure the program code similarity. Compared with other state-of-the-art LCS solutions, the proposed algorithm has higher efficiency and lower time complexity in most experimental cases.

A method is proposed to estimate the background in video sequences with dense moving objects. The velocity field is estimated by optical flow to determine the image areas occupied by moving objects. The background is estimated by an efficient averaging process within the regions excluding the moving objects, which overcomes the foreground-occluding problem in common averaging method in a dynamic environment such as heavy traffic. The experimental results on traffic surveillance videos prove the effectiveness of the proposed method.

Echo state networks have become increasingly popular for its superior performance in the field of time series prediction. However, it is difficult to implement the complicated ESN topologies in practice. To solve the problem, we propose a diagonal connected reservoir structure with composite functions inside the nodes. The input is first processed by wavelet functions and then passes through sigmoid activation functions. This increases the diversity of the reservoir. A selection method that takes into account the domain of the input data is applied to initialize the wavelet translation and dilation parameters. The output weights are efficiently computed by the least square method after the reservoir state matrix is formed. We exhibit the merits of our model on a benchmark multivariate chaotic dataset and a real-world application. Experimental results substantiate that the proposed model can achieve significantly good performance with a low-dimensional reservoir.

Five scenarios for different combinations were optimized and analyzed of hybrid energy system. The best energy and environmental performances are achieved by hydrogen technology and fuel cell, also the use of hydrogen energy is more efficient and less expensive then primary renewable energy seasonal storage by batteries.
