В.; Місюра С. Ю.; Місюра Є. Ю. Короткий огляд (реферат): Розроблено метод розрахунку на динамічну міцність багатошарового скління автомобілів спеціальної техніки при ударі твердим тілом. Визначені маса та швидкість ударника, за яких напруження в склінні досягають допустимих значень. Отримані залежності дозволяють підібрати параметри елемента скління, а також оцінити його надійність за різних умов експлуатації.

Короткий огляд (реферат): A qualitative analysis of the so-called Andronov’s system of two differential equations is carried out. The conditions for the existence of limit cycles around two singular points, which are complex foci, are considered. The previously obtained calculation results, which are generally accepted for describing this system, are based on the maximum possible cyclicity for such special points in a ratio of 3:1. In this study, a non-trivial example of a quadratic system of two differential equations with two control parameters is proposed, for which the existence of six limit cycles in the ratio 3:3 was found. To verify this result, two different methods applied to determining the cyclicity of singular points of the complex focus type were used. This result can be considered as a significant contribution to the solution of Gilbert's sixteenth problem for the case of a quadratic system of differential equations.

Короткий огляд (реферат): This paper examines the role of student motivation as a key factor in improving the quality of higher education in the context of digitalization and educational transfor-mation. It emphasizes the importance of intrinsic motivation, which enhances stu-dents’ engagement, academic performance, and capacity for self-development. The paper analyzes internal and external factors influencing motivation, as well as com-mon challenges such as stress, uncertainty about future careers, and lack of clear goals. It also highlights the role of lecturers and effective pedagogical interaction in fostering a supportive learning environment and sustaining students’ motivation.
