Abstract

The article presents the results of studies on parametric approximation in spaces R2 (functions of one variable), R3 (functions of two variables) and Rn(n>3) (functions of three or more variables). Various classes of functions satisfying a priori conditions were studied: f(0, 0, 0)=0, lim1xi→+∞ (x1, …, xn)=ci$\mathop {\lim 1}\limits_{{x_i} \to + \infty } \,\,({x_1},\, \ldots ,\,{x_n}) = {c_i}$, ci = cont. Working algorithms and C/C++ software functioning in Microsoft Visual Studio 2019 system in Microsoft Windows 10 environment were developed. The main studies of the authors were aimed at developing effective computational algorithms for constructing approximating functions of two variables from various given classes of three-dimensional data samples (three-dimensional interconnected time series). The article provides a detailed description of the problem statement, introduces classes of approximating functions, provides algorithms for estimating the parameters of approximating functions and a description of the software. The estimation algorithm considered in the article is constructed according to the scheme of the coordinate descent method with optimization of the step length (Gauss-Seidel method).

Abstract

Mathematical models and numerical methods for the optimal solution of inverse forming problems monolithic panels with contact stamp devices have been developed. Using the minimization criterion for damage in functionals of inverse problems, the optimal laws of deformation in creep are found. The algorithms implemented in MSC.Marc allow to model and evaluate the parameters of the technological processes for the manufacture of parts, in particular reconfigurable multi-point form-creation.

14. Effect of Magnetic Fields on the Optical Density of Magnetic Emulsions With Low Interfacial Tension

Author

Belykh, Sergey S. and Yerin, Constantine V.

Abstract

In this letter, the features of the optical effect of changing the optical density of a magnetic emulsion with a low interfacial tension areinvestigated. A change in the sign of the effect was found with an increase in the duration of exposure to a longitudinalmagnetic field. The interpretation of the effect is based on the approximation of anomalous diffraction. It is shown that the change in the sign of the effect of changing the optical density is associated with the coalescence of microdroplets of the magnetic emulsion under prolonged exposure to a magnetic field.

Abstract

Представлены результаты исследований, раскрывающие постановку физического воспитания в трёх университетах в части формирования физической культуры личности. Установлено, что из всех опрошенных студентов первого и четвертого курсов (n=650) максимальное количество баллов, свидетельствующих об уровне освоения физической культуры, который можно оценить как физкультурную деятельность, набрали всего 11,11 % студентов-юношей и лишь 3,99 % девушек Роль преподавателей в выборе студентами определённого вида физической активности сводится у юношей первого курса к 26,94 % случаев, четвертого – 14,71 %, у девушек первого курса – 38,53 %, четвертого – 21,45 %, то есть по мере учёбы в вузе влияние преподавателей снижается. Опрошенные студенты-бакалавры внесли много идей по совершенствованию постановки физического воспитания. The results of studies that reveal the setting of physical educationat three universities in the formationof thephysical culture of the individual. Found that of all the students surveyed first-and fourth-year(n =650), the maximum score indicating the level of development of physical culture, which can be considered as fitness activities, scored only 11,11 % of the students-boys and only 3,99 %. The role of women teachers in the selection of students a certain kind of physical activity is reduced in boys freshman year to 26,94 % of the cases, the fourth – 14,71 %, girls first year – 38,53 %, the fourth – 21,45 %, that is, to the extent study in high school teachers influence reduced. Surveyed undergraduate students have many ideas for improving the staging of physical education.
