Exploring mental health experiences and supports among international engineering undergraduate students – insights to inform university support

ABSTRACT This study explores the mental health perceptions, expectations for mental healthcare, and use of existing mental health services among international engineering students at a Western Canadian university. Employing a phenomenological qualitative approach, semi-structured interviews were conducted with 18 international undergraduate engineering students to understand their mental health challenges and service usage. The thematic analysis revealed three significant themes: students’ understanding of mental health; their experiences within the engineering programme, and recommendations to enhance and facilitate a positive mental health experience at the university. Findings suggest that mental healthcare for international engineering students should be responsive to the students’ unique needs, providing support and accessible services during their transition from their home countries and recognising the impact of the environmental and cultural factors on their experiences as members of the Faculty of Engineering and the broader university community.

Active travel in the university setting: Assessing the effects of social behavior, socioeconomics, and spatial location

University campuses are pooling efforts to promote active mobility to reduce their negative impacts on the urban environment, which is significantly influenced by the overreliance on motorized modes of transport. Providing sufficient and safe accessibility conditions for active travel has been highlighted as a crucial strategy for transforming campuses into more livable and sustainable areas in cities. To further explore the likelihood of active mobility uptake at university campuses, this study explored university students’ mobility patterns over time, examining the role of social behavior, socioeconomics, and spatial location factors. The Faculty of Engineering at the University of Porto, Greater Oporto, Portugal, provided the empirical focus for this research. The data analyzed were acquired through surveys of representative samples and spatial analysis over the academic years of 2012, 2017, and 2023. The statistical analysis explained the tendencies and multifactorial influences on travel behavior among university students. Results indicated that travel distance is associated with housing options and travel costs, whereas access to a metro station was associated with walking or cycling. Hence, this study contributed to a deeper understanding of active travel behavior. It provided insights to guide planning practitioners and decision makers in creating integrated transport policy packages that address the barriers and needs of the university community and the surrounding neighborhoods.

Comparative Study of Energy Consumption Intensity: A Case Study of the Faculty of Electrical Engineering and Informatics (FEI) Versus the Faculty of Chemical Technology (FChT) in the City of Pardubice

Abstract The study’s comparative aspect between the Faculty of Electrical Engineering and Informatics (FEI) and the Faculty of Chemical Technology (FChT) buildings is pivotal for elucidating nuanced differences in energy consumption practices within academic institutions, facilitating targeted energy efficiency measures. The research methodology adopts a comparative case study approach to examine two focal research buildings. Analysis entails computing energy consumption intensity per unit area for both buildings and comparing energy consumption data to identify disparities. The need for understanding energy consumption patterns and improving energy efficiency in academic infrastructure is directly addressed through variables studied in the comparative analysis, including energy consumption comparison, annual and monthly variations, ratio, and intensity. The data indicates that the average heating intensity in the FChT building surpasses that of the FEI building by a factor of 2.3, signifying significant disparities in heating energy consumption trends between the two structures and suggesting potential areas for targeted energy efficiency interventions. Moreover, the average electrical intensity in the FChT building is over 1.7 times higher than in the FEI building. Interestingly, despite the FChT building being 2.6 times larger than the FEI, its intensity does not always correspond with the increase in building area, indicating additional factors influencing energy consumption.

Challenges and opportunities: Implementing diversity and inclusion in software engineering university level education in Finland

Considerable efforts have been made at the high school level to encourage girls to pursue software engineering careers and raise awareness about diversity within the field. Similarly, software companies have become more active in diversity and inclusion (D&I) topics, aiming to create more inclusive work environments. However, the way diversity and inclusion are approached inside software engineering university education remains less clear. This study investigates the current state of D&I in software engineering education and faculties in Finland. An online survey (N = 30) was conducted among Finnish software engineering university teachers to investigate which approaches and case examples of D&I are most commonly used by software engineering teachers in Finland. In addition, it was researched how software engineering teachers perceive the importance of D&I in their courses. As a result of the quantitative and thematic analysis, a framework to identify attitudes, approaches, challenges and pedagogical strategies when implementing D&I themes in software engineering education is presented. This framework also offers a process for integrating D&I themes for the curriculum or at the faculty level. The findings of this study emphasize that there is a continuing need for diverse-aware education and training. The results underline the responsibility of universities to ensure that future professionals are equipped with the necessary skills and knowledge to promote D&I in the field of software engineering.

Multi-strategy improved Runge Kutta optimizer and its promise to estimate the model parameters of solar photovoltaic modules

Harnessing the potential of solar photovoltaic (PV) technology relies heavily on accurately estimating the model parameters of PV cells/modules using real current-voltage (I-V) data. Achieving optimal parameter values is essential for the performance and efficiency of PV systems, necessitating the use of advanced optimization techniques. In our endeavor, we introduce a multi-strategy improvement approach for the Runge Kutta (RUN) optimizer, a cutting-edge tool used for tackling this critical task in both single-diode and double-diode PV unit models. By aligning experimental and model-based estimated data, our approach seeks to reduce errors and improve the accuracy of PV system performance. We conduct meticulous analyses of two compelling case studies and the CEC 2020 test suite to showcase the versatility and effectiveness of our improved RUN (IRUN) algorithm. The first case study involves a standard dataset derived from the well-known R.T.C. France silicon solar cell, where IRUN performs favorably compared to competing methods, demonstrating its effectiveness. IRUN effectively manages the complex task of defining model parameters for an industrial PV module situated at the Engineering Faculty of Düzce University in Turkey. The real-world I-V data, obtained under optimal conditions with a temperature of and solar radiance of , provide strong evidence of the practical applicability and real-world benefits of our innovative method. Additional analyses through three-diode and PV module models further confirm the efficacy of the IRUN. A mean absolute error of down to 6.5E-04 and root mean square error of down to 7.3668E-04 are achieved. Our approach provides a practical and efficient tool for improving the accuracy of PV systems, enhancing their performance when compared to existing methods.

Effect of Areca Nut Fiber and Pineapple Leaf Fibers and Polyester Composition on Mechanical Properties of Composite

The Effect of Areca Nut Fiber and Pineapple Leaf Fibers and Polyester Composition on Mechanical Properties of Composite Diva Akbar*, Dody Yulianto Mechanical Engineering Study Program, Faculty of Engineering, Islamic University of Riau Jl. Kaharuddin Nasution Km 11 No.113 Perhentian Marpoyan, Pekanbaru Telp. 0761 – 674635 Fax. (0761) 674834 Email : divaakbar@student.uir.ac.id ABSTRACT Areca nut fiber and pineapple leaf fiber are types of fiber derived from natural fibers that are interesting to research as composite reinforcing fibers because currently they are very abundantly available. This research aims to make composite boards made from areca nut fiber and pineapple leaf fiber with polyester resin metrics for mechanical strength. This research varied different mixtures starting from areca nut fiber: pineapple leaf fiber: polyester resin, namely 20%: 30%: 50%, 25%: 25%: 50%, 30%: 20%: 50% using The hand lay up method was carried out three times in making composite board specimens. The highest bending strength results in sample one with a mixture of 20% areca nut fiber, 30% pineapple leaf fiber and 50% polyester resin were 52.60 Mpa, the impact value was 0.379 Joules/mm2. This is because there is the influence of the fiber and metric mixture which causes the elasticity modulus value to increase and because there is the influence of fiber density, where the smaller the density value the greater the mechanical strength, both bending strength and impact value. This phenomenon can be seen from macro observations, namely that composite boards experience fiber pull out with a fibrous brittle fracture type.
