In this context, the current de-cline in the number of first-year students in civil engineering, environmental engineering, geodesy and traffic engineering appears all the more alarming. Surveys which can provide basic data for the elimination of the shortage of skilled workers in engineering and the increase in the number of first-year students in the above-mentioned degree programmes were started surveys among pupils, students and representatives of state authorities in 2022. Furthermore, one of the surveys was used to analyse the …

European And National Strategies Supporting The Implementation And Development Of Continuing Engineering Education At Scandinavian Universities, Ida Marie Lybecker Korning, Bente Nørgaard

Research Papers

Lifelong learning (LLL) and continuing engineering education (CEE) have been on the European Union’s agenda for almost three decades, formally initiated by the European Year of Lifelong Learning in 1996 and reinforced with several initiatives targeted at LLL since then. The current initiative, the European Year of Skills 2023, aims to promote a mindset of reskilling and upskilling. Nonetheless, before 1996, some universities were already developing diverse CEE activities and collaborating with external stakeholders such as the local industry. Many of these activities, however, have been initiated by passionate university staff or based on personal relationships within the organization. CEE …

Exploring The Reliability, Time Efficiency, And Fairness Of Comparative Judgement In The Admission Of Architecture Students, Lotte Van Den Heuvel, Nina Lotte Bohm

Research Papers

It is common in architecture education to quantify the quality of assignments into grades, often done by one or two teachers using rubrics. However, this can have several downsides. It suggests an objective preciseness that is debatable for the creative assignments in the field of architecture, and the assessment is dependent on the judgement of only one or two people. Comparative judgement (CJ) offers an alternative to rubric-based assessment by applying pairwise comparison to student assignments, resulting in a ranking instead of a grade.

We used a mixed methods approach to compare the reliability, time efficiency, and fairness of CJ …

First-Generation Engineering Students' Identity Development: Early Forays Into The Workplace, Renee Smit

Research Papers

In the context of global shortages of engineering professionals, research into factors that impact on training and retention of qualified engineers is important – this includes first-generation engineering students, a largely under-researched group of students. Research has shown that an elaborated, well-developed engineering identity is important for the retention of both engineering students at university, and for engineers in practice. Professional identities are fluid, emerging and develop over the lifetime of the professional. However, we still know little about the nature of a professional engineering identity, and how it develops.

Drawing on insights from the philosophy of science, I make …

Research Papers

The digitalization of engineering education has made significant progress in recent years not only due to societal circumstances such as COVID-19, but also thanks to technological development and progress and digital transformation of engineering education seems more imminent than ever. This paper presents the development of a framework and process for an ongoing scoping review regarding frameworks for digital transformation of engineering education. Empirical studies on digital innovations in specific small-scale contexts are numerous and the literature is rich. This study, however, aims to identify more systematic and holistic approaches to digital transformation. At this stage the review work has …

The Challenge Of Postdoc’Ing In The Us: Perspectives From International Engineering Postdoctoral Scholars, Sylvia Mendez, Kathryn Watson, Jennifer Tygret

Research Papers

An intrinsic case study explores the challenges shared by international engineering postdoctoral scholars about working in the United States (US). Little research has been devoted to their experiences despite their stark increase in the postdoctoral labor force over the last decade. Semi-structured interviews were conducted with eight engineering postdoctoral scholars hailing from Canada, China, Colombia, Iran, Italy, and Thailand. Participant interviews were analyzed inductively and resulted in four themes: (1) Immigration concerns; (2) Strains to find a community; (3) Pressure to publish and secure funding; and (4) Inadequate career counseling. The identified themes could be particularly instructive to Ph.D. advisors …

Transnational Collaboration On Lifelong Learning Between Higher Engineering Education Institutions: A University Perspective, Jens Bennedsen, Geir Egil Dahle Øien

Research Papers

Lifelong learning (LLL) is in focus in all European countries. Workforce upskilling and reskilling are seen as central elements in ensuring national competitiveness. Universities are main players in this effort but often find it difficult to find sustainable models for LLL activities, in terms of e.g., economy, student intake, and academic resources. Collaboration between universities can be one possible way forward to overcome such obstacles, and given the enhanced post-Covid digitalization is also increasingly made possible, even across borders. However, many universities also find such collaboration challenging, e.g., due to outdated legislation, lacking financial predictability, lacking

A Multimodal Measurement Of The Impact Of Deepfakes On The Ethical Reasoning And Affective Reactions Of Students, Vivek Ramachandran, Cécile Hardebolle, Nihat Kotluk, Touradj Ebrahimi, Reinhard Riedl, Patrick Jermann, Roland Tormey

Research Papers

Deepfakes - synthetic videos generated by machine learning models - are becoming increasingly sophisticated. While they have several positive use cases, their potential for harm is also high. Deepfake production involves input from multiple engineers, making it challenging to assign individual responsibility for their creation. The separation between engineers and consumers may also contribute to a lack of empathy on the part of the former towards the latter. At present, engineering ethics education appears inadequate to address these issues. Indeed, the ethics of artificial intelligence is often taught as a stand-alone course or a separate module at the end of …

Are Engineering Teachers Ready To Leverage The Power Of Play To Teach Transversal Skills?, Siara Isaac, Yousef Jalali, Natascia Petringa, Roland Tormey, Jessica Dehler Zufferey

Research Papers

What conceptions do teachers hold about learning activities to develop students’ transversal skills? This qualitative exploration at a research-intensive engineering school draws on interviews and focus groups to explore teachers’ ideas about developing individual transversal skills. We frame our analysis with a model that distinguishes three phases for skill development: conceptual knowledge (knowing), procedural skills (doing) and meta-cognitive/emotional reflection (learning from doing). We are particularly interested in the potential for play to create favorable conditions for developing transversal skills by enabling (i) focused experiential learning, (ii) low-stakes experimentation, (iii) rapid feedback, (iv) opportunity for reflection.

Conceptualizing Socially Shared Regulation In Challenge-Based Learning, Karolina Doulougeri, Gunter Bombaerts, Michael Bots, Jan D. Vermunt

Research Papers

Students in Challenge-based learning (CBL) courses work in multidisciplinary groups to develop a solution to an open-ended and ill-defined challenge.Thus, in CBL, students need to regulate their learning individually and collectively to learn. Socially shared regulation of learning (SSRL) refers to the development of collective and coconstructed task perceptions or shared goals by multiple students working as a group. Existing knowledge about conceptualizing and researching SSRL in CBL is currently lacking. In this paper, we provide evidence from a qualitative study we conducted in a CBL course, using analysis of individual learning portfolios and in-depth interviews about students’ perceptions of …

Developing Teamwork Skills Through Simultaneous Group Project Courses, Tuomo Eloranta

Research Papers

The popularity of project-based learning (PBL) has led to a situation where engineering students take several group project courses at the same time. From a student perspective, this can generate considerable issues. Previous research has indicated that already single PBL courses can be challenging, especially time and task management-wise and intuitively overlapping PBL courses compound this complexity. As existing literature on this topic is relatively sparse, the goal of the present study is to examine what kind of student challenges simultaneous PBL courses generate, how students navigate those and what kind of additional learning can it foster. The results should …

Disruptions To The “Modeled Minority” In Engineering: Why Do Some Asian American Students Leave Engineering?, Michelle Choi Ausman, Qin Zhu

Research Papers

Asian American students are the largest non-White racial group in US undergraduate engineering, but they are often labeled as the "model minority." This stereotype confines them to STEM majors, limiting their access to diversity, equity, and inclusion (DEI) programs. Little attention has been given to why some Asian American students leave engineering. To address this gap, a pilot study using semi-structured interviews aims to explore the reasons behind their decision to leave the field or change their major. The study seeks to contribute to engineering education scholarship by promoting more inclusive learning environments for Asian American students and providing recommendations …

A Look Inside The Engineering Students’ Backpack: Differences In Engineering Capital According To Gender Or Migration Background., Mieke Cannaerts, Sofie Craps, Veerle Draulans, Greet Langie

Research Papers

Every student has a unique combination of experiences, resources and social networks related to engineering, called ‘engineering capital’, derived from Archer’s concept of ‘science capital’. The engineering capital gathered throughout life creates a backpack that impacts someone’s aspirations to study engineering, as well as the performance and persistence in the programme itself. Engineering technology is one of the most homogeneous fields within the STEM domain, being mostly white and male. To stimulate a more diverse engineering technology field, this research paper investigates the relationship between the level of engineering capital and gender or migration background, as well as the influence …

Reflection On Your Personal Perspective Through Other Perspectives. A Step In Dealing With Wicked Problems, Pleun Hermsen, Sjoerd Van Dommelen, Paula Hueso Espinosa

Workshops

Don’t we all sometimes seek the perspective of someone unrelated to our work, to get unstuck, or when we seek creativity? Engineers, educators, and students put their trust into science, protocols, procedures and models. Rightfully so, from the perspective of the laws of engineering this makes sense. This also explains why when people deal with challenges, they often tackle them (consciously or unconsciously) with their preferred strategies (Hayashi 2018) (Mezirow 2000). However, these preferred strategies might offer a false sense of security because they oversimplify the complicated nature of the challenge. People might focus on a part of problem which …

How To Use New Tools To Integrate Sustainability Into Engineering Teaching, Sarah Jayne Hitt, Jonathan Truslove, Cindy Cooper

Workshops

Recently, three projects have addressed the challenge that while many excellent resources on sustainability education exist, there aren’t many that explicitly guide engineering educators to integrate these into their teaching, or indeed that are intended to upskill engineering academics to be able to deliver this teaching. These projects are the Reimagined Degree Map project undertaken by Engineers Without Borders UK (sponsored by the Royal Academy of Engineering), the Sustainability Toolkit project undertaken by the UK’s Engineering Professors’ Council (sponsored by Siemens and the Royal Academy of Engineering), and the Engineering for One Planet Framework and two companion guides, co-created by …

Promoting Engineering To K12 Students Through Spatially Challenging Making And Outreach Activities, Gavin Duffy, Marten Westerhof, Deborah Keogh, Colm O'Kane

Workshops

Outreach activities are an important and valuable approach to promoting engineering education and careers to young people. They provide an excellent way to show that engineering can be fun, challenging and rewarding. With some careful thinking, they can also be used to promote and develop spatial ability, a cognitive ability that is very important to engineering. The purpose of this workshop is to demonstrate examples of outreach activities that are the result of such careful thinking. Those who attend this workshop will be able to:

1. Explain why and how spatial ability is so important to success in engineering education
2. Summarise …

Mechanical Engineering Faculty Publications and Presentations

Nanofluids based on vegetal oil with different wt.% of carbon nanotubes (CNT), hexagonal boron nitride (h-BN), and its hybrid (h-BN@CNT) were produced to investigate the effects of these nano-additives on the thermal conductivity and rheological properties of nanofluids. Stable suspensions of these oil/nanostructures were produced without the use of stabilizing agents. The dispersed nanostructures were investigated by SEM, EDS, XRD, and XPS, while the thermal conductivity and rheological characteristics were studied by a transient hot-wire method and steady-state flow tests, respectively. Increases in thermal conductivity of up to 39% were observed for fluids produced with 0.5 wt.% of the hybrid …

Metabolomic Insights Into Tuberculosis: Machine Learning Approaches For Biomarker Identification, Miftahul Khair Akbar, Arief Aulia Rahman

Indonesian Journal of Medical Chemistry and Bioinformatics

The lung parenchyma is largely impacted by the infectious condition known as pulmonary tuberculosis (pulmonary TB) when the immune system creates a wall around the germs in the lungs, a tiny, hard bulge known as a tubercle develops, earning the disease the name tuberculosis. Although the majority of TB germs target the lungs, they can also harm other bodily organs. The identification of TB biomarkers, which are crucial for diagnosis, treatment monitoring, risk analysis, and prognosis, has been the subject of extensive research. Differences in metabolites between normal cells and tuberculosis are considered to be able to support the diagnosis …

Semi-Supervised Learning Method For The Augmentation Of An Incomplete Image-Based Inventory Of Earthquake-Induced Soil Liquefaction Surface Effects, Adel Asadi, Laurie Gaskins Baise, Christina Sanon, Magaly Koch, Snehamoy Chatterjee, Babak Moaveni

Michigan Tech Publications, Part 2

Soil liquefaction often occurs as a secondary hazard during earthquakes and can lead to significant structural and infrastructure damage. Liquefaction is most often documented through field reconnaissance and recorded as point locations. Complete liquefaction inventories across the impacted area are rare but valuable for developing empirical liquefaction prediction models. Remote sensing analysis can be used to rapidly produce the full spatial extent of liquefaction ejecta after an event to inform and supplement field investigations. Visually labeling liquefaction ejecta from remotely sensed imagery is time-consuming and prone to human error and inconsistency. This study uses a partially labeled liquefaction inventory created …

Furthering Development Of Smart Fabrics To Improve The Accessibility Of Music Therapy, Ellie Nguyen, Daisy Z. Fernandez-Reyes, Franceli L. Cibrian

Engineering Faculty Articles and Research

In this paper, we present the design and development of HarmonicThreads, a smart, cost-effective fabric augmented by generative machine learning algorithms to create music in real time according to the user's interaction. In this manner, we hypothesize that individuals with sensory differences could take advantage of the fabric's flexibility, the music will adapt according to users' interaction, and the affordable hardware we propose will make it more accessible. We follow a design thinking methodology using data from a multidisciplinary team in Mexico and the United States. Then we will close this paper by discussing challenges in developing accessible smart fabrics …

Feature Distillation From Vision-Language Model For Semisupervised Action Classification, Asli Çeli̇k, Ayhan Küçükmani̇sa, Oğuzhan Urhan

Turkish Journal of Electrical Engineering and Computer Sciences

The training of supervised machine learning approaches is critically dependent on annotating large-scale datasets. Semisupervised learning approaches aim to achieve compatible performance with supervised methods using relatively less annotation without sacrificing good generalization capacity. In line with this objective, ways of leveraging unlabeled data have been the subject of intense research. However, semisupervised video action recognition has received relatively less attention compared to image domain implementations. Existing semisupervised video action recognition methods trained from scratch rely heavily on augmentation techniques, complex architectures, and/or the use of other modalities while distillation-based methods use models that have only been trained for 2D …

Increased Ductility Of Ti-6al-4v By Interlayer Milling During Directed Energy Deposition, Rakeshkumar Karunakaran, Luz D. Sotelo, Hitarth Maharaja, Calsey Nez, Monsuru Ramoni, Scott Halliday, Sushil Mishra, Joseph A. Turner, Michael P. Sealy

Department of Mechanical and Materials Engineering: Faculty Publications

Additive manufacturing (AM) often results in high strength but poor ductility in titanium alloys. Hybrid AM is a solution capable of improving both ductility and strength. In this study, hybrid AM of Ti-6Al-4V was achieved by coupling directed energy deposition with interlayer machining. The microstructure, residual stress, and microhardness were examined to explain how interlayer machining caused a 63% improvement in ductility while retaining an equivalent strength to as-printed samples. Interlayer machining introduced recurrent interruptions in printing that allowed for slow cooling-induced coarsening of acicular α laths at the machined interfaces. The coarse α laths on the selectively machined layers …

Eeg Functional Connectivity In Infants At Elevated Familial Likelihood For Autism Spectrum Disorder, Christian O'Reilly, Scott Huberty, Stefon Van Noordt, James Desjardins, Nicky Wright, Julie Scorah, Sara Jane Webb, Mayada Elsabbagh, Basis Team

Publications

Background

Many studies have reported that autism spectrum disorder (ASD) is associated with atypical structural and functional connectivity. However, we know relatively little about the development of these differences in infancy.

Methods

We used a high-density electroencephalogram (EEG) dataset pooled from two independent infant sibling cohorts, to characterize such neurodevelopmental deviations during the first years of life. EEG was recorded at 6 and 12 months of age in infants at typical (N = 92) or elevated likelihood for ASD (N = 90), determined by the presence of an older sibling with ASD. We computed the functional connectivity between …

Multi-View Brain Tumor Segmentation (Mvbts): An Ensemble Of Planar And Triplanar Attention Unets, Snehal Rajput, Rupal Kapdi, Mehul Raval, Mohendra Roy

Turkish Journal of Electrical Engineering and Computer Sciences

3D UNet has achieved high brain tumor segmentation performance but requires high computation, large memory, abundant training data, and has limited interpretability. As an alternative, the paper explores using 2D triplanar (2.5D) processing, which allows images to be examined individually along axial, sagittal, and coronal planes or together. The individual plane captures spatial relationships, and combined planes capture contextual (depth) information. The paper proposes and analyzes an ensemble of uniplanar and triplanar UNets combined with channel and spatial attention for brain tumor segmentation. It investigates the significance of each plane and analyzes the impact of uniplanar and triplanar ensembles with …

Enhancing Exploration-Exploitation In Harmony Search For Airborne Hyperspectral Imaging Band Selection (E3hs), Mohammed Abdulmajeed Moharram, Divya Meena Sundaram

Turkish Journal of Electrical Engineering and Computer Sciences

Hyperspectral imaging has emerged as a prominent area of research in the field of remote sensing science. However, hyperspectral images (HSIs) pose a notable challenge due to the presence of numerous irrelevant and redundant spectral bands exhibiting high correlation. Therefore, it is necessary to enhance the classification performance for HSI processing by selecting the most relevant discriminative spectral bands. To this end, this paper introduces a metaheuristic search method called enhancing exploration-exploitation in harmony search (E3HS). The standard harmony search suffers from many weaknesses, such as premature convergence and falling easily into the local optimum. Consequently, E3HS was proposed to …
