This paper discusses the performance of different relational databases using query analysis and optimization under different conditions. The three most popular relational databases are PostgreSQL, MySQL and MS SQL. The basic query execution time for different numbers of operators, columns, and rows was taken as the main criterion. As a result of experiments, it was determined that all databases with small amounts of stored information in the basic configuration operate in accordance with the declared performance. However, with small amounts of data, PostgreSQL is the most preferred option for use, since it is the fastest to process information. It has also been proven that MS SQL has the largest rate increment when increasing the number of columns from all databases under investigation.

The temperature dependence of the conductivity of a composite material with a conductive filler and dielectric matrix is calculated in this work. A qualitative model of conductivity is obtained depending on such parameters as the coefficient of linear expansion, distances between particles, particle sizes, and the difference between the Fermi energy in the conductor and the bottom of the conduction band in the dielectric. Also in this paper, a formula for the probability of a particle passing through a potential rectangular barrier is derived.

As a result of the analysis of existing methods for determining the equivalent circuits parameters, it was ascertained that not taking into account the initial data from the intermediate slip range 1 > s > smax when synthesizing equivalent circuits for induction motors with one- and especially dual-circuit rotor leads in some cases to the appearance of "humpback" or dips in their starting characteristics. The paper proposes a hybrid parameter estimation method for a T-shaped single-loop equivalent circuit of an induction motor with a squirrel-cage rotor, based on a combination of iterative algorithm, associated with the solution of a nonlinear algebraic equation system (basic algorithm), and numerically more stable non-iterative calculations. The need to use the non-iterative method is associated with the violation of resistance and inductive reactance ratio of the rotor circuit for certain types of induction machines at nominal slip and at slip s = 1, as well as with the problems of obtaining a global extremum when solving nonlinear algebraic equation systems. The performance of the proposed method has been tested for all high-voltage induction motors of thermal condensing power plants power units auxiliaries with rated power of 200 MW and 300 MW, as well as a power unit of a combined-cycle thermal power plant with a rated power of 450 MW.
通过对现有等效电路参数确定方法的分析，确定了在合成具有单线、特别是双线转子的异步电动机等效电路时，如果不考虑中间转差范围1 > s > smax的初始数据，在某些情况下会导致其出现“驼背”现象或起动特性下降。本文提出了一种基于组合迭代算法的鼠笼转子感应电机t形单回路等效电路的混合参数估计方法，该方法与求解非线性代数方程组(基本算法)相关联，具有数值上更稳定的非迭代计算。对于某些类型的感应电机，在标称转差和转差s = 1时，转子电路的电阻和感应电抗比的破坏，以及在求解非线性代数方程组时求全局极值的问题，都需要使用非迭代法。在额定功率为200mw和300mw的热凝电厂的所有高压感应电动机、机组辅机以及额定功率为450mw的联合循环火电厂的一台机组上进行了性能试验。

The uncoordinated charging of electric vehicles has several negative effects on the charging station and the electric network. These effects include both technical and economic aspects. So, in this paper, coordinated charging/discharging scheduling of electric vehicles in charging stations is proposed to maximize the revenue of charging stations. The problem is formulated as a linear optimization problem and is solved using the Particle swarm optimization technique (PSO). Three case studies are undertaken including uncoordinated charging, coordinated charging and coordinated charging/discharging. The results display that smart charging/discharging scheduling for the system under study increases the revenue of the charging station in comparison to the uncoordinated charging.

Despite the wide variety of automated information educational resources, they all have one common problem – low didactic efficiency. The reason for this is the complexity of the mathematical description of the semi-structured parts of the educational process and the lack of a unified mathematical approach to the formalization of educational components. Another problem is a narrow technical approach to design, in which learning systems are seen only as technical devices. At the same time, complex problems associated with the design in the field of philosophy of education, pedagogy, psychology, control theory, and circuitry engineering lack due attention. The purpose of the research is to identify problematic features that reduce the efficiency of information educational systems design. The article presents the results of the analysis of the efficiency of training systems in various forms of testing and methodology for the use of information educational resources. The features of the formalization of synergetic ergatic models of the educational process components are reviewed, considering the psychodiagnostics of the personality traits of the educational process participants. The practical significance of the research is that it provides the information system creators with alternative psychological and pedagogical methods allowing to improve the efficiency of teaching system design.

The study considered the degree of reduction in the efficiency parameters of a parabolic reflector caused by free vibrations. Estimates of the research results for various types of amplitude functions are given. It was discovered that the most negative reduction in efficiency is caused by low frequency oscillations. This leads to strong changes in the distribution of surface currents and the strength of the electromagnetic field at the focus of the reflector. It has also been found that the properties of an oscillating reflector change to a lesser extent if the amplitude function is characterized by a high density of nodes and antinodes.

Due to the processes of the immersion system and liquid respiration, there is an increase in human adaptation to external factors of space flight, which increases the efficiency of the crew. However, to analyze the cardiorespiratory system through the registration of the respiratory system is a time-consuming task. This article develops a technique for isolating respiratory waves from a cardiosignal. The processing method makes it possible to allocate human respiratory waves in various conditions of being space flight. At the end of the article, a set of output data of the method is presented. The data describe human respiratory waves.

The necessity of turbogenerators’ operation in the reactive power consumption mode is determined by the shortage of compensating devices in the network. Recently, accidents associated with generators’ long-term operation at low levels of excitation have become more frequent, which is a prerequisite for the consumption of reactive power by the generator. The purpose of this research is to assess the effect of the reactive power consumption mode on the technical condition of the T3FP-110-2MU3 turbogenerator. Data obtained from operating and repair documentation, electrical and thermal test protocols, technical reports containing the results of complex diagnostic examinations of the turbogenerator served as a source of information on the technical condition of the turbogenerator.

The paper presents the practical comparing of feature extraction methods in speech by the example of isolated words (commands) recognition and comparing the performance of a set of features using different classification algorithms. In this case, a consistently increasing set of keyword samples is used for the training set. Approaches based on cepstral coefficient extraction (including MFCC- and GFCC-based variations), linear prediction (LPCC), and wavelet transform (via Basilar-membrane Frequency-band) are considered. The obtained results indicate that in some cases (including recognition tasks) the use of features other than MFCC allows to increase the accuracy of recognition from 1 to 7 percent. At the same time, the statements of the authors of other approaches to the extraction of speech features about the significant superiority of their methods over MFCC are not confirmed.
