This paper proposes a minimal length difference algorithm for construction of a line in an image by solving the problem of optimal contour approximation. In this algorithm, a method for finding interest points is proposed, and the object matching (classification) is done by mapping interest points onto a vector space. In cases where the lines in the representation of the images are not smooth, the algorithm converges rapidly. The results of the experiments showed that for convergence of the contour simplification, there were 5-6 iterations for n = 13. To check how close the curve approximation ...Более
The article discusses the matrices of the form A(n)(1), A(n)(m), A(N)(m), whose inverses are: tridiagonal matrix A(n)(-1) (n - dimension of the A(N)(-m) matrix), banded matrix A(n)(-m) (m is the half-width band of the matrix) or block-tridiagonal matrix A(N)(-m) (N = n x m - full dimension of the block matrix; m - the dimension of the blocks) and their relationships with the covariance matrices of measurements with ordinary (simple) Markov Random Processes (MRP), multiconnected MRP and vector MRP, respectively. Such covariance matrices frequently occur in the problems of optimal filtering, ext ...Более
The luminescence spectral properties of alkali metal fluorides and the influence of various impurity and intrinsic defects have been studied intensively for many years. However, research is still urgently needed on the mechanism of energy transfer to luminescence centers in thermostimulated processes, particularly in systems with pair activation. This is important not only for an understanding of the mechanisms of localization, migration, and relaxation of electronic excitations, but also in a particularly practical aspect - for the development of new, effective thermoluminophores, scintillato ...Более
В данной работе представлены результаты прямой лазерной записи на двухкомпонентной среде, состоящей из нанесенных методом магнетронного напыления слоев аморфного кремния и серебра на стеклянную подложку. Лазерное воздействие проводилась сфокусированным излучением одномодового полупроводникового лазера с длиной волны λ = 405 нм на слой аморфного кремния со стороны стеклянной подложки. На электронном микроскопе TESCAN VEGA 3 LMH исследовано формирование рельефа на пленке серебра при прямой записи импульсами полупроводникового лазера с λ = 405 нм на подслое а-Si.
It is a well-known fact that the system is as secure as its weakest point. Often, organizations and countries invest in the technologies, forgetting that it is impossible to assure information security without raising awareness among users. Therefore, in this study, the cybercrime awareness rate of users in two Central Asian Countries was investigated. As a target group, students of two public universities from each country were chosen. Results of quantitative research showed that in Kazakhstan, gender and age of respondents affect the cybercrime awareness rate, while in Kyrgyzstan, none of th ...Более
When learning languages, writing an essay is one of the main methods for assessing students’ knowledge. However, with the development of ICT, language learning is also being transferred to online platforms. At the same time, as the number of students’ increases, the problem of evaluating students’ essays arises. In this paper, we offer an automated system that facilitates instructors while evaluating students’ essays. Currently, the system works for essays written in Turkish. The system was built using the Zemberek library. It allows one to extract text features the essay of several people at ...Более

Целью данной работы является исследование отношения учащихся к случайному выбору вопросов при компьютерном тестировании в высших учебных заведениях. Исследование проводилось в виде опроса студентов. Респондентам предлагалось указать степень их согласия на применение в компьютерном тестировании случайного выбора вопросов на промежуточных (модулях), финальных, вступительных экзаменах, а также в целях самостоятельного определения уровня знаний. В исследовании приняли участие 1034 студента, представляющих 6 высших учебных заведений Кыргызстана. По результатам исследования получены следующие выводы ...Более
