Calculus is an important undergraduate mathematics course in engineering programmes, which gives the foundation for engineering subjects like mechanics or electronics. Unfortunately, recent experiences show that the performance of students admitting after the pandemic has deteriorated dramatically in recent years. This research aims to analyse the changes in performance and attitudes of first-year students in the aftermath of the pandemic. In our research, we investigated the performance and learning habits of three groups of first-year mechatronics and energy engineering students during Calculus-1 and the related Mechanics subject. The “2018 group” studied maths traditionally, whereas the “2020 group” took online education in the last months of high school and the first year of university. The “2022 group” spent two years of high school at home in remote learning (the significant 10-11th grades, for maths competence), but received in-person education at the university. Learning habit and performance of the students were monitored using EduBase online educational platform. The results of both the qualitative and quantitative analysis have revealed that online education during the pandemic changed the learning habits of the group in 2020 and had only slight effects on their performance in Calculus and Statics. However, for group 2022, where the pandemic affected high-school maths studies, the performance at the university has fallen dramatically resulting in an increased drop-out rate after the first semester. © 2023 SEFI 2023 - 51st Annual Conference of the European Society for Engineering Education: Engineering Education for Sustainability, Proceedings.

We developed finite element models to simulate the impact tests described in the international assessment protocol of wrestling mats. The accuracy of the finite element analysis was validated with experimental data. We showed the nonlinear viscoelastic nature of the foam material by determining the relationship between the damping ratio and maximum compressive strain. We demonstrated the applicability of the method through the quality assessment of wrestling mats, and determined the minimum required thickness to prevent traumatic head injuries. The modeling and testing method can be implemented in the study of sandwich structures, thus the design process can be simplified. With further development, our approach can be used to design multilayered wrestling mats with better energy absorbing characteristics.}, year = {2022}, eissn = {1873-2348}, orcid-numbers = {Kossa, Attila/0000-0003-3638-3237; Berezvai, Szabolcs/0000-0002-6399-583X; Kmetty, Ákos/0000-0001-6029-3229} } @CONFERENCE{MTMT:32706623, title = {Structure and Properties of Thermally Activated Polymer Foams with Controlled Porosity and Tunable Mechanical Properties}, url = {https://m2.mtmt.hu/api/publication/32706623}, author = {Younghoon, Kwon and Eileen, Seo and Berezvai, Szabolcs and Claus, D.
