The integration of artificial intelligence (AI) in manufacturing significantly impacts employment,
leading to both displacement and transformation of jobs. While low-skilled positions are at risk due to
automation, new roles requiring advanced skills are emerging, necessitating effective reskilling initiatives.
This dual effect presents challenges and opportunities for the workforce. Policymakers must develop
strategies to mitigate job losses while harnessing AI’s potential for increased productivity and economic
growth.
Cultural awareness is a critical skill in today's interconnected world, fostering mutual respect and understanding in
diverse societies. This study explores the role of self-education in enhancing cultural awareness among students at Taiz
University. By examining recent literature and student practices, the findings highlight the benefits of self-directed learning in
developing cultural competence, promoting global perspectives, and encouraging lifelong learning habits. The study
emphasizes the importance of integrating self-education techniques into academic programs to prepare students for a
multicultural world.
Разработана компьютерная конечноэлементная модель технологического процесса холодной штамповки крышки люка полувагона. Получены распределения эквивалентных напряжений в заготовке и инструменте на различных стадиях процесса. Установлена зависимость глубины внедрения штампа от силы, реализуемой при прессовании. Определены значения минимальной силы, необходимой для формовки изделия, при различных значениях предела текучести материала заготовки.
A computer finite element model of the technological process of cold stamping for the gondola car hatch cover has been developed. The distributions of equivalent blank and tool stresses during the stages of the process have been received. The depth of punch penetration - force implemented during pressing dependence has been determined. The calculation of the minimum force necessary for molding products for different yield strength of blank material has been done.
Modern methods of sustainable development are crucial for addressing global challenges such as
climate change and resource scarcity. By promoting renewable energy, sustainable agriculture, and urban
initiatives, these practices foster economic growth and social equity. Continued collaboration and effective
policies are essential for scaling these efforts and ensuring a prosperous future.
Разработана методика определения гидродинамической нагруженности котла вагона-цистерны с учетом взаимодействия с перевозимой жидкостью. При моделировании взаимодействия системы «жидкость - металлоконструкция котла» применен метод конечных элементов для численного решения уравнений Навье-Стокса и неразрывности, широко используемых при моделировании гидродинамики жидкого груза, и уравнения динамики упругой конструкции котла. Выполнен комплекс расчетов нагруженности котла цистерны при ударном воздействии на вагон, в результате которого определены давления жидкого груза на внутреннюю поверхность котла при его различном заполнении. Исследования показали, что учет деформаций стенок котла при его взаимодействии с перевозимым жидким грузом приводит к уточнению давлений от транспортируемой жидкости. Установлено, что расхождение результатов расчета гидродинамической нагруженности котла, представленного абсолютно твердым телом и при учете его податливости, достигает 55 %.
The technique of definition of the hydrodynamic loading of the boiler of the tankcar is developed in view of interaction with a transported liquid cargo. At simulation of interaction of system « fluid - the boiler » the finite element method is applied for a numerical solution of the equations of the Navier-Stokes and the continuity which used at simulation of hydrodynamics of a liquid cargo, and the equation of dynamic of an elastic construction of the boiler. The complex of calculations of loading of the boiler of the cistern is executed at impact effect on a coach as a result of which pressure of a liquid cargo upon an internal surface of the boiler are defined at its different filling. Researches have shown, that the account of strains of walls of the boiler at its interaction with a transported liquid cargo reduces to the adjusting of pressure from transported liquid cargo. It is established that the divergence of results of calculation hydrodynamic loading of the boiler attains 55 %.
This paper examines the crucial role of law in protecting public and personal property
from cyber-attacks. It highlights the challenges posed by outdated legislation, varying enforcement,
and the need for international cooperation. The findings emphasize the importance of adaptive legal
frameworks and public awareness in combating cybercrime effectively.
This paper explores the transformative impact of artificial intelligence (AI) on marketing research and practices. It
examines how AI technologies streamline data collection, processing, and analysis, significantly enhancing the efficiency and
effectiveness of marketing strategies. The global market for AI-based software is projected to grow substantially, reflecting
the increasing reliance on AI to improve business processes. Key applications of AI in marketing include data aggregation,
customer interaction through chatbots, personalized advertising, and predictive analytics.
Рассмотрены новизна и практическая значимость трансдисциплинарного проектирования объектов и силовых систем, применяемого в рамках трибофатики - науки об износоусталостных повреждениях и разрушении указанных систем.
The paper considers the novelty and practical importance of transdisciplinary design of facilities and active systems applied in the
framework of Tribo-Fatigue – the science of wear-fatigue damage and destruction of these systems.
Обобщается многолетний опыт преподавания трибофатики в трех университетах Республики Беларусь. Изложение студентам достижений трибофатики в рамках учебной дисциплины способствало повышению общего уровня подготовки инженеров-механиков в Белорусском государственном университете транспорта, Белорусском государственном университетете, Гомельском государственном техническом университете им. П. О. Сухого.
The paper summarizes two decades of experience teaching the course «Fundamentals of Tribo-Fatigue» in BelSUT. The presentation of achievements of Tribo-Fatigue students within an academic discipline, no doubt, contributes to the level of training of mechanical engineers in the Belarusian State University of Transport.
