Deep indentation and puncture is a promising alternative as it is an information-rich measurement with the potential to be performed in a high-throughput manner. Despite its promise, the method lacks standardized protocols, and open questions remain about its possible limitations. Addressing these shortcomings is vital to ensure consistent methodology, measurements, and interpretation across samples and labs. To fill this gap, we examine the role of finite sample dimensions (and by extension, volume) on measured forces to determine the sample geometry needed to perform and unambiguously interpret puncture tests. Through measurements of puncture on a well-characterized elastomer using systematically varied sample dimensions, we show that the apparent mechanical response of a material is in fact sensitive to near-wall effects, and that additional properties, such as the sliding friction coefficient, can only be extracted in the larger dimension case where such effects are negligible. © 2024 The Royal Society of Chemistry.}, keywords = {Friction; sampling; High-throughput; Sample volume; Mechanical characterizations; Characterization techniques; Measurements of; Sample geometry; Soft-solid; Softer materials; Finite samples; Near-wall effects}, year = {2024}, eissn = {1744-6848}, pages = {3806-3813}, orcid-numbers = {Berezvai, Szabolcs/0000-0002-6399-583X} } @inproceedings{MTMT:35660380, title = {Intervention in engineering students' maths education to overcome the aftermath of distance learning}, url = {https://m2.mtmt.hu/api/publication/35660380}, author = {Berezvai, Szabolcs and Köpeczi-Bócz, Ákos Tamás and Sándor, Tibor and Kun, László Ákos and Szilágyi, Brigitta}, booktitle = {SEFI 2024 - 52nd Annual Conference of the European Society for Engineering, Proceedings}, doi = {10.5281/zenodo.14254868}, unique-id = {35660380}, abstract = {During the pandemic, many people in secondary school failed to acquire solid and profound knowledge. Teaching maths in remote education with distance learning has been a challenge for both teachers and students. In engineering higher education, several years after the pandemic, we are seeing problems that are having an impact on the overall education not only in the basic subjects but in further engineering subjects. There is a need for an intervention programme that can be applied effectively in large-scale courses where the number of students exceeds 100. Recently, we have created supplementary courses to help students learn the advanced Calculus material more effectively, while ensuring that they can catch up with their secondary school knowledge at their own pace. This research aims to analyse the changes in student performance of first-year student during the first two semesters of university math courses (Calculus 1 and 2). In our research, we investigated three different groups of students: the “2018 group” studied math traditionally, while the “2020 group” took online education at the end of high school and at the beginning of their university studies. Finally, the “2022 group” spent two years in high school at home in distance learning but started in-person education at the university and had significant problems during the first semester. Therefore, those students participated in an intervention programme. The performance analysis after Calculus 2 shows that we have succeeded in developing an inclusive pedagogical programme that we intend to further develop in the future to reduce drop-out. © 2024 SEFI 2024 - 52nd Annual Conference of the European Society for Engineering, Proceedings: Educating Responsible Engineers.

The Student Research Societies (SRS) were initiated by talented students who, with the help of their mentors, want to achieve more than what regular education could offer. The inception was followed by dynamic horizontal and vertical expansion. Nowadays, more than 10, 000 students participate in the scientific student society movement in Hungary. A legally codified structure deeply embedded in higher education has emerged. Students prepare scientific papers on topics of their choice with scholarly ambition, engage in research group activities, and present their findings at institutional SRS events. Based on recommendations from a professional jury, authors of worthy papers can participate in the biennial national conference. The National Conference of Student Research Societies (NCSRS) hosts competitions in 16 thematic sections accompanied by numerous community programs. Since 2023, the SRS has become an international event within the framework of the European Engineering Learning Innovation and Science Alliance program. The SRS is a HIP that significantly enhances both students' learning experiences and outcomes, enriching many with the joy of research and scientific collaboration. This paper examines the last decade of the Technological Sciences Section, analyzing the satisfaction surveys of the 2019, 2021, and 2023 NCSRS events. We compare the measurement results of the online event held during the pandemic in 2021 with those before and after COVID-19, examining how the pandemic has impacted scientific student association activities. © 2024 SEFI 2024 - 52nd Annual Conference of the European Society for Engineering, Proceedings: Educating Responsible Engineers.

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.
