Safety Systems

The problem of quantitative analysis of safety of microelectronic and microprocessor systems of railway automation and telemechanics is considered. The problem remains relevant, since the subject of safety analysis is rarely occurring, but extremely dangerous events. The risk and significance of failure are selected as the main safety features of these systems. The way to identify a failure was chosen according to MILSTD‑1629A standard, as the most adequate.Calculated expressions for significance of a failure are proposed. The probability of a dangerous failure is calculated by the method of model analysis. It is proposed to calculate the probability of a failure further developing into an accident using scenario analysis methods by constructing event trees. Calculated ratios for ratings of violations are suggested, allowing to compare dangerous failures and emergency sequences developed from a failure. The risk assessment of operation of railway automation systems was selected not related to economic categories, and thus convenient for rationing. It is based on probabilistic concepts of the nature of risk and is calculated using the methods of probability theory. The developed design ratios and models make it possible to analyze performance of the functions of train traffic safety systems by methods common to control systems, at the same time reflecting the features of operation of railway automation.

The subject area of the article is the work of a modern organization to counter the threat of corruption from its officials. Persons Specific forms of implementing corruption threats in the commercial, financial, production, technological and personnel areas of the business entity are specified, their negative impact on market positions is determined. The thesis is argued that the degree of protection from the threat of corruption by its own persons is rightfully considered as an additional competitive advantage of any subject of professional entrepreneurship or, accordingly, its competitive disadvantage. The concept of a “workplace with a corruption component” is disclosed and their list in a modern commercial organization is specified. Personal qualities and other characteristics of a candidate for employment or an employee already in the staff are determined, which exclude the possibility of replacing such workplaces. Recommendations are formulated and argued for the introduction of four groups of HR technologies implemented within various areas of the corporate personnel management system and ensuring effective prevention or prompt identification of relevant threats in order to acquire additional competitive advantages for the subject of professional entrepreneurship. The first group of technologies is used in the process of selecting candidates for replacement of jobs with a corruption component. The purpose of their implementation is to identify individual characteristics, the presence of which calls into question both the overall loyalty of the applicant and its “anti-corruption stability.” The second group of technologies involves the prevention of corruption through the use of special tools for the economic motivation of personnel. The third group of technologies provides the possibility of both prevention and detection of the threats under consideration and involves the use of special control procedures when concluding business contracts and contracts for a large business size of a particular organization. Finally, the fourth group of technologies is used to monitor the activities of employees replacing jobs with a corruption component.

Abstract This research presents a methodology for creating mivar knowledge bases in tabular-matrix form for ground intelligent vehicle control systems. At its core, this methodology is kind of instruction for analysts facing the task of formalizing knowledge in a given subject area. The result of this formalization is a “knowledge map” created according to a special proposed template. In the future, this template allows forming a knowledge base for a given subject area in the formalism of bipartite oriented mivar networks. As an example, the subject area of ground-based intelligent vehicle control systems is used as a template. The proposed methodology of knowledge formalization makes it possible to simplify the process of creating models in Wi!Mi “Razumator-Consultant” 2.1 and also to level the probability of logical collisions when designing a knowledge model in the formalism of bipartite oriented mivar networks.

This paper offers an approach for evaluating the significance of individual characteristics of recognized objects. The scope of this approach is not the subject area where objects and characteristics of these objects are specified, but a trained ∑Π - neural network that works correctly on the specified subject area. In this paper, we propose a method for constructing a crucial function based on the weight characteristics of a correctly functioning ∑Π - neuron. A logical derivative is used to evaluate the significance of object characteristics. This makes it possible to track how the decision function will change its value if one or more object characteristics change their value. This will allow us to draw a conclusion about the most important properties of the subject area under consideration.

The development of a general concept and implementation of a data-storage and analysis system for practice oriented data, one of the subsystems of which is an analytical system for the accumulation and analysis of data from users of social networks, is topical. The development of a general concept and implementation of a data-storage and analysis system for practice oriented data, one of the subsystems of which is an analytical system for the accumulation and analysis of data from users of social networks, is topical. Data that users leave about themselves in social networks can be useful in solving various tasks. The proposed article describes the subject area associated with the collection and storage of data from users of social networks. Proceeding from the subject area, the general architecture of the universal data collection and storage system is proposed, which is based on the client-server architecture. For the server side of the system, a fragment of the data model is provided, which is associated with the accumulation of data from external sources. The framework of the system architecture is described. The developed universal system is based on the information technology of data warehousing, and it has the following aspects: an expandable complex subject area, the integration of stored data that come from various sources, the invariance of stored data in time with mandatory labels, relatively high data stability, the search for necessary trade-off in data redundancy, modularity of individual system units, fl and extensibility of the architecture, high security requirements vulnerable data.The proposed system organizes the process of collecting data and filling the database from external sources. To do this, the system has a module for collecting and converting information from third-party Internet sources and sending them to the database. The system is intended for various users interested in analyzing data of users of social networks.

The article analyzes the philosophical and cultural view of “doctor’s professional culture” as a result of centuries-old practice of human relations, which is characterized by constancy and passed from generation to generation. Medicine is a complex system in which an important role is played by: philosophical outlook of a doctor, philosophical culture, ecological culture, moral culture, aesthetic culture, artistic culture. We have found that within the system “doctor-patient” the degree of cultural proximity becomes a factor that influences the health or life of a patient. Thus, the following factors are important here: 1) communication that suppresses a sick person; 2) the balance of cultural and intellectual levels; 3) the cultural environment of a patient which has much more powerful impact on a patient than the medical one.At the present stage, the interdependence of professional and humanitarian training of future specialists is predominant, as a highly skilled specialist can not but become a subject of philosophizing. We outlined the sphere where the doctors present a genre variety of philosophizing (philosophical novels, apologies, dialogues, diaries, aphorisms, confessions, essays, etc.). This tradition represents the original variations in the formation of future doctor’s communicative competences, which are formed in the process of medical students’ professional training.A survey conducted among medical students made it possible to establish their professional values, which are indicators of the formation of philosophical and culturological competence. It was found out that 92% of respondents believed that a doctor should demonstrate a high level of health culture (avoid drinking and smoking habits, etc.)99% of respondents favoured a high level of personal qualities of a doctor which would allow methods and forms of medical practice to assert higher human ideals of truth, goodness and beauty that are the subject area of cultural studies and philosophy.

Introduction. The article is devoted to the problems of the essence and content of judicial ethics in the new conditions of the technical revolution and with other social needs for legal regulation. Theoretical Basis. Methods. The work used a systematic, activity-personal approach to the study of moral and ethical standards of the conduct of judges. This made it possible to reveal a new and broader view on judicial ethics, which is not simply a set of moral restrictions and obligations imposed on a judge. Results. The work has identified and analysed the signs of judicial ethics at the current stage of development. It is argued that ethical regulation is precautionary in relation to the legal regulation of the independence of judges, for they complement ethical rules and reinforce legal norms. The ethical conduct of judges is an instrument guaranteeing judicial independence in all of its manifestations, including in organisational and judicial relations. The new realities of our time recognise the expansion of boundaries and the subject area itself of ethical regulation. A broader view on judicial ethics, which differs from the traditional one, is hereby justified. The latter is defined in two ways – namely both as a system of professional values, as well as a means of judicial administration based on the principle of self-regulation. By its very nature, judicial ethics is the result (and the way) of judicial self-governance, developed on the basis of the experience of functioning bodies of the judicial community. Discussion and Conclusion. Conclusions are drawn on both the instrumental and the managerial impact of the categories of ethics. The subject of judicial ethics has been defined, which constitutes the rules of conduct of judges in the performance of their professional duties and beyond – namely the set of general principles of work of a judge, as well as the personal qualities of a judge personifying the judicial power. Proposals on the optimisation of the mechanism of ethical influence, differentiation of ethical and disciplinary norms have also been substantiated.

Achievement test is of very important assessment tool to evaluate the student’s current level of knowledge and skill acquired from classroom instruction. This test is designed to evaluate the student’s level of achievement in a particular subject for a particular class prescribed under the board or the university. In other words, to assess how much the pupils have achieved the educational objectives in teaching learning process at the end of the course and if achieved then to what extent, it has been achieved. Achievement tests are proved to be very helpful in various ways to the people who are involved in the field of education such as the teachers, the administrators, the planners, to the parents as well as for the students. The teacher very carefully develops and conduct achievement test in the class which enable the teacher to get an overall idea of the progress or the level of achievement of his students in the subject area. The teacher can determine the pupil’s strength and weakness in the subject area. So, based on this the teacher can take necessary remedial instructional strategies for the betterment of the pupil’s progress. In the same time, it also provides feedback for the teaching efficiency of the teacher.As with the time changes there have been many educational reforms taken place and in between syllabus had also been changed under different Boards of Studies. In order to maintain uniform standard of education the Government has formulated a policy to implement NCERT syllabus common to all School Boards throughout the country and accordingly the State Board of Secondary Education, Assam (SEBA) follow NCERT syllabus and to evaluate students’ achievement in terms of the policy formulated by the Board. Till now, no any standardized achievement test has been conducted for the secondary school students of Assam. Therefore, the investigators felt to construct and standardize an achievement test in the subject General Science which will definitely help in educational research.

The Subject

In an ideal world, assessment should be synonymous with effective learning and reflect the intricacies of the subject area. It should also be aligned with the ideals of education: to provide equitable opportunities for all students to achieve and to allow both appropriate differentiation for varied contexts and students and comparability across various contexts and students. This challenge is made more difficult in circumstances in which the contexts are highly heterogeneous, for example in the state of Queensland, Australia. Assessment in music challenges schooling systems in unique ways because teaching and learning in music are often naturally differentiated and diverse, yet assessment often calls for standardization. While each student and teacher has individual, evolving musical pathways in life, the syllabus and the system require consistency and uniformity. The challenge, then, is to provide diverse, equitable, and quality opportunities for all children to learn and achieve to the best of their abilities. This chapter discusses the designing and implementation of large-scale curriculum as experienced in secondary schools in Queensland, Australia. The experiences detailed explore the possibilities offered through externally moderated school-based assessment. Also discussed is the centrality of system-level clarity of purpose, principles and processes, and the provision of supportive networks and mechanisms to foster autonomy for a diverse range of music educators and contexts. Implications for education systems that desire diversity, equity, and quality are discussed, and the conclusion provokes further conceptualization and action on behalf of students, teachers, and the subject area of music.
