HEURISTIC METHODS FOR SOLVING THE CREATIVE PROBLEMS

Abstract. The development of non-standard thinking helps in solving creative problems. People who think formally can not come up with anything new, thereby destroying creativity. The creative task is an excellent way of revealing the personal abilities of each person. The development of creative thinking allows people to realize their creative potential, their individuality. Heuristic methods in solving problems allow us to express creative thoughts and to activate the creative possibilities of man. Creative thinking is very closely related to the imagination, which is important in any profession. Features of creative thinking consist in the fact that it contributes to the non-standard solution of certain tasks. An unconventional thinking person is able to offer bright ideas in any field of activity, that is, creative activity generates something new, different in originality, originality, and uniqueness. The system of heuristic methods of solving problems is based on logic, sound mind and experience, and the result of all this is new significant information. When solving creative problems, various heuristic methods are used. This is a method of brainstorming, a method of heuristic questions, a method of multidimensional matrices, a method of free association, a method ofinversion, a method of empathy, a method of synectics. The work reveals the essence of each heuristic method, as well as the merits and demerits of each of them. We consider various forms of employment in heuristic ways of teaching, such as the olympiad, heuristic exercises, business games, interactive forms.Keywords: creative task, heuristic methods, methods, non-standard questions, forms

Optimum Shapes of Supercavitating Hydrofoils at Zero Cavitation Number

Abstract: We investigate the problem of the flow around a supercavitating hydrofoils at zero cavitation number. Making use of formulas for the lift and drag, derived in the work by D. V. Maklakov (J. Fluid Mech, 2011, vol. 687, pp. 360–375), we dtermine the hydrofoil shape that provides the minimum drag coefficient at a given lift coefficient. This ensures the maximum lift-to-drag ratio

Security threats and methods of protecting websites of paid educational services of educational institutions

With the increase in the number of paid educational services of educational institutions, the percentage of fraudulent actions committed, both in relation to web services and in relation to service purchasers, also increases. Therefore, all participants in the process of banking transactions, i.e. the totality of operations that accompany remote interaction between the user and the payment system, must be protected from such actions, which determines the introduction and development of anti-fraud technologies used in the virtual space of the global Internet. Errors in the protection of websites, including websites of paid educational services of educational institutions, continue to be one of the most common shortcomings in ensuring the protection of information. Such errors, i.e. vulnerabilities, are exploited by attackers who attack websites in order to steal valuable information. It also increases the likelihood of subsequent penetration into the corporate information systems of educational institutions. Therefore, there is a need to use specialized tools and methods to protect web applications
