The regularized asymptotics of a solution of the Cauchy problem for systems of singularly perturbed ordinary differential equations is constructed. It is shown that a power boundary layer appears in such problems in addition to other boundary layers.
In this paper, we investigate the nonlinear problem of the optimal vector control for oscillation processes described by Fredholm integro-differential equations in partial derivatives when function of external sources nonlinearly depend on control parameters. It was found that the system of nonlinear integral equations,which obtained relatively to the components of the optimal vector control, have the property of equal relations. This fact lets us to simplify the procedure of the constructing the solution of the nonlinear optimization problem. We have developed algorithm for constructing the s ...More
This study was conducted to see the attitudes of students toward web-based learning environment in General Physics course. The study was conducted in a public university in Kyrgyzstan in 2018. 144 students from the faculty of Science and Engineering participated in the study. Online questionnaire was completed online at the end of the spring semester 2017-2018. In addition, in-depth interviews with 12 students were conducted. Results showed that students’ success in online Physics course depends on gender and academic major of students. Factors, that were defined in this study: advantages over ...More
The various types of ultrafilter-completeness on zero-sets of uniformly continuous functions are introduced, their properties are studied and characterizations in the category are given.
In this study, we give some estimates on the Nikolskii-type inequalities for complex algebraic polynomials in regions with piecewise smooth curves having exterior and interior zero angles.
The estimation of the modulus of algebraic polynomials on the boundary contour with weight function, having some singularities, with respect to the their quasinorm, on the weighted Lebesgue space was studied in this current work.
Exact estimates for Faber polynomials, norm of Faber operator, and -norm of the generating function for the sequence of Faber operator of univalent functions of class sigma are found. The description of continua of the complex plane for which the norm of Faber operator take the value 1 or 3 is obtained.
Multilingual and multicultural educational environments have often appeared on the agenda of educational scientists especially since the end of the twentieth century. The objective of this study is to increase student academic success by determining the expectations of students from lecturers who teach in their own mother tongue and in another language. Thus, it aims to help make the education delivered in multilingual and multicultural environments more effective. This is a qualitative study that adopts the survey design. The working group of the study consists of 53 students (28 females and ...More
Purpose The purpose of this paper is twofold: first, it analyses the relationship between educational level, the school-to-work transition period for youth and positions which suffer from an education-job mismatch in Kyrgyzstan; and second, it investigates the effect of the education-job mismatch on the wages of youth in Kyrgyzstan. Design/methodology/approach The study uses the International Labor Organization 2013 data from the school-to-work transition survey for Kyrgyzstan. The Kaplan-Meier failure analysis is employed to demonstrate the relationship between school-to-work transition and m ...More
We study the uniform and mean convergence of the generalized Bieberbach polynomials in regions having a finite number of interior and exterior zero zero angles.
We continue our investigation of the order of growth of the modulus of an arbitrary algebraic polynomial in the Bergman weight space, where the contour and weight functions have certain singularities. In particular, we deduce a Bernstein-Walsh-type pointwise estimate for algebraic polynomials in unbounded domains with piecewise asymptotically conformal curves with nonzero inner angles in the Bergman weight space.
