Three Phase Inverter

The FOPID and PID controller are designed to control the speed of <br /> the BLDC motor. The parameters , , , λ and µ of these controller are optimized based on genetic algorithm. The optimized coefficients keep in track with zero error signals. The output of the controller is given to the variable dc source which varies the input voltage to the three phase inverter depending on the input signal. The three phase inverter gives the voltage to the BLDC motor which enhances the stability of the system. <br /> The effectiveness of the controller is demonstrated by simulation.

For analyzing and evaluating the deformation features of channel goaf foundation and its effect on superstructure, according to the foundation reinforcement engineering of Ji-Liang Channel Check Gate, the comparative analysis on the differential settlement between the unfavorable foundation and natural foundation was performed by numerical simulation with FLAC3D. The computer results showed that the present foundation had obvious effect on the stability and security of the superstructure, so the engineering treatment are needed. Based on technical-economic comprehensive analysis among three treatment methods for strengthening the channel golf foundation with different kinds of filling, the reasonable method is put forward in this paper. By comparing mechanical characteristic of flashboard in channel goaf before and after strengthening, we confirmed the foundation stability of channel goaf and the security of the ground building which can satisfy the long term usage requirements.

Sensitivity diagnostics has recently been put high on the agenda of methodological research into Qualitative Comparative Analysis (QCA). Existing studies in this area rely on the technique of exhaustive enumeration, and the majority of works examine the reactivity of QCA either only to alterations in discretionary parameter values or only to data quality. In this article, we introduce the technique of combinatorial computation for evaluating the interaction effects between two problems afflicting data quality and two discretionary parameters on the stability of QCA reference solutions. In this connection, we challenge a hitherto unstated assumption intrinsic to exhaustive enumeration, show that combinatorial computation permits the formulation of general laws of sensitivity in QCA, and demonstrate that our technique is most efficient.

This article is devoted to the comparison of two object-relational mapping systems supported by .NET platform - Entity Framework Core and NHibernate. The research hypothesis “framework NHibernate is more efficient than Entity Framework Core in the context of DML operations” was put forward. In order to make an efficiency analysis of ORM frameworks, a desktop application was designed and implemented to enable testing and visualization of results. The NHibernate framework turned out to be much more efficient than Entity Framework Core in single tests and slightly faster in bulk tests. The stability of both frameworks was similar.

The authors present a methodology for using financial indicators to assess the value of companies. The article is dedicated to a comprehensive research of EBITDA. As a research objective, the authors identified an attempt to solve the problem of companies’comparability with identical proportions of financial results, the possibility of identifying the most financially stable companies. Based on the analysis of various interpretations, applying of this indicator in different directions is considered. As a component of various coefficients that characterize the company’s financial stability, it’s recommended to use the EBITDA indicator. The behooves and opportunities that open up when using it are revealed. The research shows to the need to apply this indicator, because this coefficient is able to more fully reveal the stability of the company, by increasing the amount of real profit, the amount of which is limited due to the presence of a large share of non-cash expenses in companies. In the process of research, such general scientific methods as monitoring, comparison, description, systematic and analytical approach, comparative analysis, scientific abstraction, expert assessment, analysis of reasons and consequences were used.

The development of the digital economy, the change in the image of workers, their values, as well as the threat of a global pandemic indicate the further development and widespread introduction of non-traditional forms of employment. The article examines the historical preconditions for the formation of a distance form of employment. The authors conclude that distance employment is an evolutionary form of employment and, in the context of the COVID-19 pandemic, is designed to ensure the stability of labor relations. The features of the legal regulation of distance work in the Republic of Belarus are analyzed, a comparative analysis of the legal regulation of distance employment in the Russian Federation is carried out. The main mistakes made by employers when transferring workers to remote work have been studied. Basic recommendations are given for transferring employees to a remote form of employment, taking into account the requirements of the legislation of the Republic of Belarus. There were used such methods as analysis, synthesis, dialectical, historical, formal logical, formal legal and comparative legal in this research.

The article examines the features of ensuring the stability of the business sector during the COVID-19 pandemic in Kazakhstan, OECD countries and other countries by analyzing the measures taken by their governments. A comparative analysis was conducted for global trends in the introduction of tax policy measures (cancellation / reduction of tax rates, the use of temporary / permanent tax deductions, benefits and loans, refundable tax benefits, etc.) and non-tax policy (provision of loans, subsidies for business expenses that are not related to with wages, various types of deferrals, and other industry-specific support measures).

The article provides a comparative analysis of epic formulas from the Shor epic with similar constructions from the Yakut olonkho formed on the basis of rhythmic and syntactic parallelism. The relevance of the study is due to the need to identify the degree of interconnection between the Yakut olonkho and the Shor epic at the level of epic formulas, which still remains outside the field of view of researchers. The novelty of the study lies in the fact that when sampling material from the Yakut epic, the author is not limited to examples from the same olonkho text, but uses a more varied approach and involves formulas from several texts. In the analysis of epic formulas, the main focus is on keywords, as well as on the general context of the peripheral components of stable constructions. As a result of the study, it is established that the analyzed examples are universals in which the uniformity of the structure and the commonality of the content are viewed. According to the author of the article, these universals are the result of a common origin and culture of peoples. It is concluded that the patterns of rhythmic-syntactic parallelism are preserved due to the stability of epic formulas and indicate a genetic relationship between the Yakut olonkho and the Shor epic.
