Metric Regularity of the Sum of Multifunctions and Applications

In this work, we use the theory of error bounds to study metric regularity of the sum of two multifunctions, as well as some important properties of variational systems. We use an approach based on the metric regularity of epigraphical multifunctions. Our results subsume some recent results by Durea and Strugariu.Comment: Submitted to JOTA 37 page

A new inverse trigonometric shear deformation theory for isotropic and functionally graded sandwich plates

A new inverse trigonometric shear deformation theory is proposed for the static, buckling and free vibration analyses of isotropic and functionally graded (FG) sandwich plates. It accounts for a inverse trigonometric distribution of transverse shear stress and satisfies the traction free boundary conditions. Equations of motion obtained here are solved for three types of FG plates: FG plates, sandwich plates with FG core and sandwich plates with FG faces. Closed-form solutions are obtained to predict the deflections, stresses, critical buckling loads and natural frequencies of simply supported plates. A good agreement between the obtained predictions and the available solutions of existing shear deformation theories is found to demonstrate the accuracy of the proposed theory

THE CURRENT SITUATION OF TRAINING STUDENTS MAJORING IN PHYSICAL EDUCATION AT CAN THO UNIVERSITY, VIETNAM

The objective of the research is to evaluate the training process for students majoring in physical education at Can Tho University in the period between 2004 and 2020. Through carefully examining and summarizing documents and surveys, the research accurately and comprehensively provides an overview of the current situation regarding the process of training physical education students at Can Tho University. The study looks at four issues: the enrollment process, graduation outcomes, graduates’ employment situations, and employers’ satisfaction level. The findings indicate that the enrolment process has been under difficulties regarding the number of enrolled students in recent years, the training quality is very good, students graduate on time, and the training products satisfy employers.  Article visualizations
