Abstract: Nowadays the teachers while lecturing various courses on the ordinary differential equations often use program systems of symbolical mathematics or computer algebra, for example MAPLE well known for its efficiency. In the process of training in computer modeling, teacher often face a problem of designing a mathematical model of the studied process. Because the fundamental laws of nature are formulated as a rule in a language of the differential equations, there is a need to teach the students to design mathematical models. The authors present a solution of the problem of the automated generation of mathematical models on the using a systems of the ordinary differential equations based on Maple system. The paper presents an example of this solution. The given algorithm of generating systems of ordinary differential equations can be easily modified for a specific task. During the course on ordinary differential equations it is necessary to give students the tasks develop the algorithm by themselves. This allows students to develop a culture of logical thinking, which will properly establish cause and effect of physical processes and phenomena from the formal implementation of interdisciplinary connections and practical orientation of training. All of this will undoubtedly contribute to a better knowledge of the disciplines of applied mathematics and other subject areas.

Abstract: The article considers the prevailing contradictions between the nature of the vulnerabilities in source code, safety requirements limitations of regulatory and methodological basis of tests and software developers who do not provide the source code for testing purposes. Methods of software products analysis that do not require the source code of programs, are widely used abroad but in our country are not well known yet. The article investigates the question can such methods and means increase the effectiveness of certification testing of software. The authors determine the necessary changes in the regulations to open up the possibility of applying the methods of testing programs without source code in the certification tests. Methods used in the study: software engineering, analysis of complex systems, the theory of reliability of complex systems, the synthesis software, compiling software. The paper shows that the use of methods for testing without source code allows to find such common vulnerabilities in the software that can’t be effectively detected because of the regulatory restrictions for the presence of source code. The experience of certification tests on the absence of undeclared features and program bookmarks, as well as independent software testing allows to determine the priority areas for improvement of the regulatory, based on the application of the methods of testing software without source code.

Abstract: The article reviews a procedure of solving the uncertainty in identifying the similarities and duplications between the results of intellectual activity, due to the presence of semantic and pragmatic ambiguity in natural language form of results description. The aim of the study is to provide identification of duplicate results of intellectual activity in an automated mode, in which experts only manage its settings by determining the composition of the classifiers used in the construction of relations of similarity, simplification of inter-agency coordination based on the results of intellectual activity and integrity of the database, as well as increasing the reliability and efficiency of the procedure identifying duplicate the results of intellectual activity by combining the frequency-semantic methods and formalized expert knowledge. The research methodology is based on a system analysis, pattern recognition, synthesis databases and knowledge bases, the automatic processing of natural language texts. The authors developed an approach for building knowledge bases classes for information representations of the results of intellectual activity that would classify its different types and systematize knowledge about the classes of intellectual property through the use of the author's method of automated classification and identification of duplications of intellectual property.

Abstract: The subject of the study is an automated functional state bioradiolokation control of pilot to ensure accountability of such an assessment in the process of operation of the aircraft in real time. The developed methods and algorithms of data processing for the first time enable the correct mathematical treatment of physiological signals that are not limited to the pilot motor activity in their registration by taking into account nonstationarity and intraspecific variability in processing signals. This, in turn, significantly increase the potential for non-contact monitoring of the status of the pilot. Methods used in the research: a systematic analysis, filtering radio signals, wavelet analysis, artificial neural networks, mathematical cybernetics, pattern recognition. The developed technique of monitoring of bioradiolokation of condition of pilot enables the diagnostics of dangerous (for reliable professional activity) states in terms of the activity of the cardiovascular and respiratory system. Implementing the results of the study provides the possibility of increasing the reliability of operation of aircraft through the use of non-contact monitoring of the state of flight personnel in order to improve the reliability of their professional activities and account evaluation of the current state circuits control the aircraft.
