Definition Of

The frequency and algebraic directions of researches of robust stability are considered. Frequency or Tsypkin-Polyaka’s direction is considered briefly in a survey order. The algebraic or Kharitonov’s direction is considered more more widely, namely basic provisions and results of the Algebraic method of robust stability of interval dynamic systems developed within development algebraic or Kharitonov’s direction of robust stability are presented. Fundamental works of V. L. Kharitonov since issue have caused a huge flow of the publications connected with extreme relevance of the solution of problems of a robustness of systems. So far from a circle of problems of a robustness many issues of robust stability are resolved. Discrete analogs and versions of theorems of Kharitonov are received. Frequency conditions of robust stability are considered and solved in Ya. Z. Tsypkin, B. T. Polyak, Yu. I. Neymark works. However in a problem of robust stability not all issues are so far resolved, especially big contradictions have arisen in a continuous case. Also the tasks considered here for interval matrixes and polyhedrons of matrixes haven’t been solved. In work the theorem like the third theorem of Kharitonov which cancels counterexamples to former known results in this direction is formulated and proved and also on its basis the costal theorem for polyhedrons of matrixes is proved. The new costal theorem also cancels counterexamples for this case. To the main theorem of the considered algebraic method the specifying remark is formulated that in the absence of a full set of four angular polynoms of Kharitonov of a condition of this theorem are necessary, but can be insufficient for stability of system. Determination of angular separate coefficients of a characteristic polynom of system is generally carried out by means of use of methods of nonlinear programming. For a discrete case the discrete analog of the theorem of Kharitonov which is received on the basis of Schur’s theorem is presented. At the same time, the concepts of points and intervals of a variabless used for the theorem of an analog of a continuous case are entered. The algorithm of definition of a robustness of discrete systems is formulated. The main results, the Algebraic method of robust stability developed by the author are illustrated with cancellation of the counterexamples widely known from scientific literature.

Definition Of

The article is devoted to the theoretical analysis of the understanding of the phenomenon of tolerance in psychology and the determination of the characteristics and probable reasons for the manifestation of such a form as tolerance of indifference, which is currently the most widespread in the world, according to the authors of this article. It is stated that there are a lot of different interpretations of the concept of tolerance in the scientific literature and they continue with an awareness of the complexity, multidimensionality and dynamic nature of this phenomenon, however, instead of identifying what unites them, which is common for the definition of tolerance, scientists are focused on attempts to offer their own, more a good understanding of it, different from the existing ones. And this actually means the absence in science of the exact meaning of this word, as well as an understanding of what exactly, what psychological phenomenon it means. And the attempts of scientists to distinguish this concept from the concept of tolerance in no way facilitate the solution of the situation. It is suggested that tolerance and intolerance should not be opposed in the context of a "positive-negative" attitude, since these concepts are not mutually exclusive, and the manifestation of intolerance under certain circumstances can be a moral phenomenon, in contrast to tolerance. It is noted that the biggest problem and still unresolved issue of the psychology of tolerance is the definition of the boundaries of manifestation of tolerance, tolerant attitude towards another person and his actions. It is concluded that the limit of the manifestation of a tolerant attitude is violation / neglect of other norms of universal human morality; that in the modern world, tolerance is not always actively manifested, more often the tolerance of indifference dominates. And it is precisely this manifestation of tolerance that has a long history (philosophical and religious), which serves as a serious basis for modern manifestations of tolerance as indifference. Tolerance of indifference is a manifestation of a stable, not always conscious, indifferent attitude to various issues of human existence, which excludes both a person's assessment of the current situation and taking responsibility for its development. The tolerance of indifference was inherited by the post-Soviet countries from totalitarianism, but the modern information society, in part, involuntarily cultivates just this kind of tolerance, gradually leveling the axiological significance of a person's moral and existential values.

Definition Of

The subject of this research is the social relations in the context of bringing to legal responsibility, as well as normative legal acts and scientific literature that reflect such relations. The problem of classification of the types of legal responsibility is relevant in the context of substantiation of the autonomy of its individual types. The attempts to substantiate the autonomy of one or another type of legal responsibility entail the revision of the grounds for classification. The goal of this article consists in revealing the natural grounds for definition of the concept of “legal responsibility” to build consistent and exhaustive classification. The main conclusion lies in determination of the criterion for classification of the types of legal responsibility. Emphasis is placed on the social relations underlying the legal relations, namely legal relations in the area of bringing to legal responsibility. On the example of responsibility for committing tax fraud, the article demonstrates the failure of attempts to find qualification criteria on the basis of the normative legal acts outside the entirety of social relations. The article determines the close link between social relations in the economic sphere, as well as their impact upon legal relations emerging in the context of bringing to legal responsibility as a whole and administrative responsibility in particular.

Difficult Issue

A very difficult issue in the theory of constitutional law is the correct definition of subjects and those legal relations in which they participate. Some can be identified immediately, seeing, for example, the passport of a citizen of the Russian Federation, but the state in its physical or other expression is more difficult to identify. This is despite the fact that most scientific literature is devoted to the relationship of these particular subjects among themselves. Collective subjects, some of which are such only in relation to the territory in which they carry out their functions, are very important in contemporary reality. This issue is devoted to this work.

Legal Understanding

The purpose of the article is to typologize terminological definitions of security, to find out the general, to identify the originality of their interpretations depending on the subject of legal regulation. The methodological basis of the study is the methods that made it possible to obtain valid conclusions, in particular, the method of comparison, through which it became possible to correlate different interpretations of the term "security"; method of hermeneutics, which allowed to elaborate texts of normative legal acts of Ukraine, method of typologization, which made it possible to create typologization groups of variants of understanding of the term "security". Scientific novelty. The article analyzes the understanding of the term "security" in various regulatory acts in force in Ukraine. Typological groups were understood to understand the term "security". Conclusions. The analysis of the legal material makes it possible to confirm that the issues of security are within the scope of both legislative regulation and various specialized by-laws. However, today there is no single conception on how to interpret security terminology. This is due both to the wide range of social relations that are the subject of legal regulation and to the relativity of the notion of security itself and the lack of coherence of views on its definition in legal acts and in the scientific literature. The multiplicity of definitions is explained by combinations of material and procedural understanding, static - dynamic, and conditioned by the peculiarities of a particular branch of legal regulation, limited ability to use methods of one or another branch, the inter-branch nature of some variations of security, etc. Separation, common and different in the definition of "security" can be used to further standardize, in fact, the regulatory legal understanding of security to more effectively implement the legal regulation of the security direction.

The Cold War

The concept of failed state came to the fore with the end of the Cold War, the collapse of the USSR and the disintegration of Yugoslavia. Political violence is central in these discussions on the definition of the concept or the determination of its dimensions (indicators). Specifically, the level of political violence, the type of political violence and intensity of political violence has been broached in the literature. An effective classification of political violence can lead us to a better understanding of state failure phenomenon. By using Tilly’s classification of collective violence which is based on extent of coordination among violent actors and salience of short-run damage, the role played by political violence in state failure can be understood clearly. In order to do this, two recent cases, Iraq and Syria will be examined.

The paper purpose is the effectiveness estimation in the technological equipment use, taking into account its reliability and productivity for defective transmission units of buses. The problem consists in the determination of time to be spent on repair of bus transmission units taking into account technological equipment reliability. In the paper there is used a probabilistic method for the prediction bus transmission units, and also a method of the dynamics of averages which allow ensuring minimum of costs for units downtime during repair and equipment cost. The need for repair of transmission units (gear box) arises on an average after 650 hours, the average productivity of the bench makes 4.2 bus / hour. The bench fails on the average after 4600 hours of work, the average time of the bench makes 2 hours. In such a way the solution of the problem specified allows analyzing the necessity of time decrease for transmission unit repair to avoid long downtimes of buses in repair areas without negative impact upon high repair quality and safety during the further operation.
