Before the start and during the first weeks of their first year, it has been observed by teachers that engineering students start with a high level of motivation, which often seems to decrease during the course of the first semesters. Such a decrease in motivation can be a main driver for students dropping out of University early. A qualitative research will be carried out to answer the main questions that have been raised within the engineering department of the Fontys University of Applied sciences: to what extent does a decrease in the motivation of first-year students exists, exactly when during the course of the first year does this decrease occur and what are the underlying reasons causing this decline in motivation? Gaining more insight in the motivation drop of students could result in modifications to the curriculum. The final objectives are reducing the dropout level of students in the first year and increasing the quality level of young propaedeutics. In [1] and [2] studies are carried out to measure student’s motivation constructs, which have been carried out for first year Engineering students. The authors describe a certain level of motivation drop for first year students at an Engineering University. In Geraedts 2010 [3] it is defined that Maslow rules for students can be seen as an element of a student’s perception onto his or hers education. Often it can be observed that in most cases undergraduates start their education as an unconscious insufficient competent student having a very limited view on the work arena and complexity of the engineering discipline. Quickly after the start of the education year this view develops into a more defined perception of what the content and complexity of the future work field is and what is expected of the student during his or hers education. It is hypothesised that this gain in insights of the student into the work field and the related expectations is a significant contributor to the decline of intrinsic motivation. In this paper the investigated hypothesis and possible other aspects that influence the motivation of students will be presented. Based on results, potential corrective and preventive measures will be defined and discussed. Corrective and predictive measures depend on the results of this study and could be aimed for instance at: 1) making adjustments to the content and/or structure of the first semester curriculum, 2) improving the support of students in making adaptations into a better learning strategy and 3) improve the information on-which students decide to start a mechanical engineering education. This paper will focus on the first year mechanical engineering students of the Fontys University of Applied Sciences. About 100 first year students will be questioned using predefined questionnaires and additionally 20 of them will be interviewed for validation. References [1] Brett D. Jones, Marie C.

In wheelchair sports, there is an increasing need to monitor mechanical power in the field. When rolling resistance is known, inertial measurement units (IMUs) can be used to determine mechanical power. However, upper body (i.e., trunk) motion affects the mass distribution between the small front and large rear wheels, thus affecting rolling resistance. Therefore, drag tests – which are commonly used to estimate rolling resistance – may not be valid. The aim of this study was to investigate the influence of trunk motion on mechanical power estimates in hand-rim wheelchair propulsion by comparing instantaneous resistance-based power loss with drag test-based power loss. Experiments were performed with no, moderate and full trunk motion during wheelchair propulsion. During these experiments, power loss was determined based on 1) the instantaneous rolling resistance and 2) based on the rolling resistance determined from drag tests (thus neglecting the effects of trunk motion). Results showed that power loss values of the two methods were similar when no trunk motion was present (mean difference [MD] of 0.6 1.6 %). However, drag test-based power loss was underestimated up to −3.3 2.3 % MD when the extent of trunk motion increased (r = 0.85). To conclude, during wheelchair propulsion with active trunk motion, neglecting the effects of trunk motion leads to an underestimated mechanical power of 1 to 6 % when it is estimated with drag test values. Depending on the required accuracy and the amount of trunk motion in the target group, the influence of trunk motion on power estimates should be corrected for.

An important step towards improving performance while reducing weight and maintenance needs is the integration of composite materials into mechanical and aerospace engineering. This subject explores the many aspects of composite application, from basic material characterization to state-of-the-art advances in manufacturing and design processes. The major goal is to present the most recent developments in composite science and technology while highlighting their critical significance in the industrial sector—most notably in the wind energy, automotive, aerospace, and marine domains. The foundation of this investigation is material characterization, which offers insights into the mechanical, chemical, and physical characteristics that determine composite performance. The papers in this collection discuss the difficulties of gaining an in-depth understanding of composites, which is necessary to maximize their overall performance and design. The collection of articles within this topic addresses the challenges of achieving a profound understanding of composites, which is essential for optimizing design and overall functionality. This includes the application of complicated material modeling together with cutting-edge simulation tools that integrate multiscale methods and multiphysics, the creation of novel characterization techniques, and the integration of nanotechnology and additive manufacturing. This topic offers a detailed overview of the current state and future directions of composite research, covering experimental studies, theoretical evaluations, and numerical simulations. This subject provides a platform for interdisciplinary cooperation and creativity in everything from the processing and testing of innovative composite structures to the inspection and repair procedures. In order to support the development of more effective, durable, and sustainable materials for the mechanical and aerospace engineering industries, we seek to promote a greater understanding of composites.

An important performance determinant in wheelchair sports is the power exchanged between the athletewheelchair combination and the environment, in short, mechanical power. Inertial measurement units (IMUs) might be used to estimate the exchanged mechanical power during wheelchair sports practice. However, to validly apply IMUs for mechanical power assessment in wheelchair sports, a well-founded and unambiguous theoretical framework is required that follows the dynamics of manual wheelchair propulsion. Therefore, this research has two goals. First, to present a theoretical framework that supports the use of IMUs to estimate power output via power balance equations. Second, to demonstrate the use of the IMU-based power estimates during wheelchair propulsion based on experimental data. Mechanical power during straight-line wheelchair propulsion on a treadmill was estimated using a wheel mounted IMU and was subsequently compared to optical motion capture data serving as a reference. IMU-based power was calculated from rolling resistance (estimated from drag tests) and change in kinetic energy (estimated using wheelchair velocity and wheelchair acceleration). The results reveal no significant difference between reference power values and the proposed IMU-based power (1.8% mean difference, N.S.). As the estimated rolling resistance shows a 0.9–1.7% underestimation, over time, IMU-based power will be slightly underestimated as well. To conclude, the theoretical framework and the resulting IMU model seems to provide acceptable estimates of mechanical power during straight-line wheelchair propulsion in wheelchair (sports) practice, and it is an important first step towards feasible power estimations in all wheelchair sports situations.

The importance of teaching engineering students innovation development is commonly clearly understood. It is essential to achieve products which are attractive and profitable in the market. To achieve this, an institute of engineering education has to provide students with needed knowledge, skills and attitudes including both technical and business orientation. This is important especially for SME’s. Traditionally, education of engineering provides students with basic understanding how to solve common technical problems. However companies need wider view to achieve new products. Universities of applied Sciences in Oulu and Eindhoven want to research what is the today’s educational situation for this aim, to find criteria to improve the content of the educational system, and to improve the educational system. Important stakeholders are teachers and students within the institute but also key-persons in companies. The research is realized by questionnaires and interviews from which a current situation can be found. The research will also include the opinion of management who give possibilities to change the curriculum. By this research more insight will be presented about how to re-design a current curriculum. The research will act as basis for this discussion in SEFI-conference about formulating a curriculum that includes elements for wide-ranging knowledge and skills to achieve innovations especially in SME’s.

In the fall of 1999, we started, the Integrated Product Development- Collaborative Engineering ( IPD-CE) project as a first pilot. We experimented with modern communication technology in order to find useful tools for facilitating the cooperative work and the contacts of all the participants. Teams have been formed with engineering students from Lehigh University in the US, the Fontys University in Eindhoven, The Netherlands and from the Otto-von-Guericke University in Magdeburg, Germany. In the fall of 2000 we continued and also cooperated with the Finnish Oulu Polytechnic. It turned out that group cohesion stayed low (students did not meet in real life), and that Internet is not mature enough yet for desktop video conferencing. Chatting and email were in these projects by far the most important communication media. We also found out that the use of a Computer Support for Cooperative Work (CSCW) server is a possibility for information interchange. The server can also be used as an electronic project archive. Points to optimise are: 1. We didn't fully match the complete assignments of the groups; 2. We allowed the groups to divide the work in such parts that those were developed and prototyped almost locally; 3. We haven't guided the fall 2000 teams strong enough along our learning curve and experiences from previous groups. 4. We didn't stick strong enough to the, by the groups developed, protocols for email and chat sessions. 5. We should facilitate video conferencing via V-span during the project to enhance the group performance and commitment.

The pace of introduction of new technology and thus continuous change in skill needs at workplaces, especially for the engineers, has increased. While digitization induced changes in manufacturing, construction and supply chain sectors may not be felt the same in every sector, this will be hard to escape. Both young and experienced engineers will experience the change, and the need to continuously assess and close the skills gap will arise. How will we, the continuing engineering educators and administrators will respond to it? Prepared for engineering educators and administrators, this workshop will shed light on the future of continuing engineering education as we go through exponentially shortened time frames of technological revolution and in very recent time, in an unprecedented COVID-19 pandemic.

Nowadays companies need higher educated engineers to develop their competences to enable them to innovate. This innovation competence is seen as a remedy for the minor profitable business they do during the financial crises. Innovation is an element to be developed on the one hand for big companies as well as for small-and-medium sized companies through Europe to overcome this crisis. The higher education can be seen as an institution where youngsters, coming from secondary schools, who choose to learn at higher education to realize their dream, what they like to become in the professional world. The tasks of the Universities of applied Sciences are to prepare these youngsters to become starting engineers doing their job well in the companies. Companies work for a market, trying to manufacture products which customers are willing to pay for. They ask competent employees helping achieving this goal. It is important these companies inform the Universities of applied Sciences in order to modify their educational program in such a way that the graduated engineers are learning the latest knowledge and techniques, which they need to know doing their job well. The Universities of applied Sciences of Oulu (Finland) and Fontys Eindhoven (The Netherlands) are working together to experience possibilities to qualify their students on innovation development in an international setting. In the so-called: ‘Invention Project’, students are motivated to find their own invention, to design it, to prepare this idea for prototyping and to really manufacture it. Organizing the project, special attention is given to communication protocol between students and also between teachers. Students have meetings on Thursday every week through Internet connection with the communication program OPTIMA, which is provided by the Oulu University. Not only the time difference between Finland and the Netherlands is an issue to be organized also effective protocols how to provide each other relevant information and also how to make in an effective way decisions are issues. In the paper the writers will present opinions of students, teachers and also companies in both regions of Oulu and Eindhoven on the effectiveness of this project reaching the goal students get more experienced to set up innovative projects in an international setting. The writers think this is an important and needed competence for nowadays young engineers to be able to create lucrative inventions for companies where they are going to work for. In the paper the writers also present the experiences of the supervising conditions during the project. The information found will lead to success-factors and do’s and don’ts for future projects with international collaboration.

This paper describes a model for education in innovative engineering. The kernel of this model is, that students from different departments of the faculty of Applied Science and Technology are placed in industry for a period of eighteen months after two-and-a-half year of theoretical studies. During this period students work in multi-disciplinary projects on different themes. Students will grow to fully equal employees in industry. Therefore it is important that besides students, teachers and company employees will participate in the projects. Also the involvement of other level students (University and high school) is recommended. The most important characteristics of the model can be summarized in innovative, interdisciplinary and international orientation.
