The problem of integrability of ordinary differential equations to find their exact solutions is a celebrated problem in the theory of differential equations which attracted attention of several workers in the area. This is due to the fact that: (a) differential equations are the most widely used continuous models of dynamic systems in physics, medicine, economics, biology and other sciences that study the surrounding reality, for which the explicit trajectory of the dynamic system's behavior is important as the explicit solution contains in itself the maximum information about the behavior of ...More
To numerically solve a system of linear algebraic equations with a tridiagonal matrix, a recursive version of Cramer's rule is proposed. This method requires no additional restrictions on the matrix of the system similar to those formulated for the double-sweep method. The results of numerical experiments on a large set of test problems are presented. A comparative analysis of the efficiency of the method and corresponding algorithms is given.
In this study, the perceived quality of higher education in the Kyrgyz Republic was analysed from the students' perspective. The factors affecting the university choice as well as factors defining the perceived quality of education were investigated using a quantitative approach. The results of the study revealed that students perceive the quality of higher education in the country as rather satisfactory. The difference was observed among responses collected from different universities. Besides, the satisfaction of students from universities located in different regions differs: surprisingly, ...More
