The theoretical basics of data-free encoding of data based on recurrent GK-codes are presented, analysis and comparison of existing coding methods and their protocols with the proposed method, the principle of GK-codes formation based on Galois code sequence and transmission of coded data-free data are substantiated. The theoretical foundations and principles of signaling codes used to manipulate bit-oriented data streams in computer system information channels are proposed, taking into account the extent of signal space utilization and signal shape, the rate of message transmission and the degree of error protection. The RSSC provides effective symmetric coding in the form of Galois codes of sequences of zeros and units of a data block, with unambiguous determination of their number that can be used to detect and correct errors after data transmission on computer systems. A special feature of the structure of this special processor is the symmetrical formation of Galois data bit signs. Moreover, the start of the Galois generator occurs according to the appearance of the first bit of zero or one in the data stream. New methods of signal-free bit encoding of bit-oriented information flows using Galois field codes have been proposed, which enable the detection and correction of one-time errors without inputting excess data streams transmitted in an optical channel. Formalization of functional structures of modules of processors of formation of hopeless codes has been formalized, as well as structures of special processors and their components have been developed, which perform the formation of Galois signal corrective codes and implement their algorithmic modeling.

Insights from three plant specific common cause failure (CCF) analyses, which used CCF Data Base and Analysis System software by US NRC, were presented in this paper. It was found that detailed guidelines/criteria were needed for performing a plant specific CCF analysis, especially for more systematic and consistent determination of the impacts of historical CCF events on a specific target system. Information collection task, impact of using unscreened independent events, and insights from specific components CCF analyses were also discussed. Finally, the following recommendations were made: (1) Develop procedures and criteria, like those developed for the plant specific CCF analyses, for more systematic and consistent plant specific CCF analysis. In developing criteria, it should be considered to credit existing plants for the enhanced defenses against CCFs based on their accumulated operating experiences. (2) Use of generic CCF data is strongly discouraged. Instead, perform plant specific CCF analysis, at least initial screening of the original events as a minimum, in order to avoid potential over-conservatism. (3) Enhance the current internet based information data bases and develop a communication network among CCF analysts in order to facilitate the information collection task.

Creative Tasks

The article is devoted to the problem of assessing the individual educational results of students in the process of additional education. This assessment in the concept of the authors is considered as the most important condition for the independent progress of the student along the individual educational trajectory. In this case, the student is the subject of its design. A model for assessing the individual educational results of students in the format of an educational event is proposed. The basic principle is formulated, which consists in fixing activity manifestations in a given situation, which testify to the student's ability to independently solve a creative task. These manifestations include: adequate understanding of the meaning of the problem being solved, competent determination of means and methods for solving it, competent access to various resources, and implementation of productive communications, ability to present and defend the solutions obtained. It is shown that the main components of such an educational event should be: joint solution of original creative tasks by students, expert-analytical support of this activity and free creative communication of different participants. A methodological scheme for the preparation and conduct of such an educational event is described. Its structural elements are: a preliminary analysis of data monitoring the development of students' creative activities; development and testing of a package of creative tasks; preparing a team of experts and equipping it with the necessary tools; development of the Festival program using a variety of creative communication formats of the participants; organization of information and analytical support of the Festival. Recommendations on the preparation of local working spaces for various types of activities of the Festival participants are given.

The theoretical foundations of changes in the transformer oil quality characteristics, depending on the aging degree, are presented. The introduction of a new indicator of the exploitational transformer oils quality – “stability against oxidation” – is substantiated as a way of solving the scientific and technical problem of assessing the resource characteristics of a transformer insulating system. In order to select the best measures to maintain the quality of power transformers insulating oils, a newly developed “Method for the Experimental Determination of the Luquid Dielectric Resource and Measures for its Restoration” is presented.

The article analyses a sufficient number of psychological literature on the problem of aggression. We have revealed the state of development of the problem under study in science, its conceptual and theoretical foundations, namely the following provisions: determination of personality behaviour by dialectical unity of external and internal (dependence of behaviour on biological and social factors); abrupt, stage personal development in ontogeny; personality development is caused by a complex influence on her psyche of heredity, environment, upbringing. The driving force behind personality development is contradiction. The development of aggression occurs in the process of socialization of the individual, and its manifestations depend on individual-psychological characteristics, social competence in the conditions of aggression, cognitive and psycho-emotional state, etc.We have found out that there are different approaches to the study of aggression, the reasons for its occurrence, to determine its nature and structure of aggressive personality behaviour. It has been established that, despite the controversy of this issue, its various interpretations, psychologists are united in the fact that aggression is a form of behaviour aimed at harming another living being. Aggressiveness is a personality trait that expresses readiness for aggression. Aggressive behaviour is a complex and multifaceted process that involves various factors, both social and biological. We have identified the prerequisites and causes of aggression in adolescence. The authors identified criteria and indicators that diagnosed the aggression of adolescents in two secondary schools: district and city. We found the levels of aggression in adolescents from both schools based on the interpretation of the obtained data. As a result of correlation measurements, we found a higher level of aggression in adolescents of urban school.

The action of affine groups on Galois field has been studied.  For instance,  studied the action of on Galois field for  a power of prime.  In this paper, the rank and subdegree of the direct product of affine groups over Galois field acting on the cartesian product of Galois field is determined. The application of the definition of the product action is used to achieve this. The ranks and subdegrees are used in determination of suborbital graph, the non-trivial suborbital graphs that correspond to this action have been constructed using Sims procedure and were found to have a girth of 0, 3, 4 and 6.

Abstract Existing association-based outlier detection approaches were proposed to seek for potential outliers from huge full set of uncertain data streams ($UDS$), but could not effectively process the small scale of $UDS$ that satisfies preset constraints; thus, they were time consuming. To solve this problem, this paper proposes a novel minimal rare pattern-based outlier detection approach, namely Constrained Minimal Rare Pattern-based Outlier Detection (CMRP-OD), to discover outliers from small sets of $UDS$ that satisfy the user-preset succinct or convertible monotonic constraints. First, two concepts of ‘maximal probability’ and ‘support cap’ are proposed to compress the scale of extensible patterns, and then the matrix is designed to store the information of each valid pattern to reduce the scanning times of $UDS$, thus decreasing the time consumption. Second, more factors that can influence the determination of outlier are considered in the design of deviation indices, thus increasing the detection accuracy. Extensive experiments show that compared with the state-of-the-art approaches, CMRP-OD approach has at least 10% improvement on detection accuracy, and its time cost is also almost reduced half.
