Range During a master course lecture many decades ago, my eminent professor in Macro-Economics (Huisman) once told us to be prepared to work in a completely different area after your graduation. His advice came in a period of economic crisis. It echoes Schumpeter's view on innovation and economic development and their joint impact on the labour market. Following his advice, I got used to adapt to opportunities offered in many fields and areas (see list below). The pay-off of this approach is job readyness and security, albeit not in the same job or place. Many people are overspecialised, which may suit their employer (for some time), but the individual may loose its ability to adapt to the requirements of an ever changing world. In an operational sense, flexibility and agility in content and above average (time) management skills allow one to switch field and focus, perspective or scale level or combine these on-demand. EQ-related skills, in particular listening without judging and other psychological principles are vital supports of one's decision-making. Being genuinely interested in what is driving other people is a prerequisite for successful interaction and personal effectiveness. Vision and mission With over two decades of experience in bachelor, minor, master and EngD education at two very different universities and well over four decades in research, including non-academic jobs, I can deal with a wide array of topics. This also gives me a good insight in the state of todays education and (many) areas for improvement. The massiness of today's education is troubling both students and lecturers. I still manage to provide individualized coaching. I strongly believe in servant leadership (Covey) as a means to motivate and manage students. Successful education is about introducing students to means that allow them to develop themselves as humans and professionals. Students should become critical consumers of theories, methodology, data sources and data processing tools and attain a good understanding of policy- and decision-making. In design, thesis and EngD projects, students experience the value of their education when working in a professional environment. You study decision-making and internal communication. You experience how many people thrive on experience instead of collecting and using real process data next to other regular, fundamental, flaws in professional decision-making. You learn to stay afloat, provide dedicated 'solutions' and manage expections of your supervisors. The final leg of a study program is what stays in the memory of graduates for decades. The same graduates may also become future commissioners. Lecturers can also learn from their students to improve themselves and their courses; it helps to regularly upgrade your course material. As native Dutch I also fully understand the psychological, cultural and political meanings of the Dutch language. Coaching students is also much easier compared to a situation in which you have to rely on English only. TIL5050 and TIL5060: Living lab experiences In education you are constantly interfacing with external parties like businesses and governments. We now have a large network of regular commissioners who offer many opportunities for design- and thesis projects. If students work with a company or government agency, they can access real (live) data. As a result, their methodology and results may and frequently also will be (directly) applied in practice and not end up in a drawer or bin like so many professional studies. This gives student research and the education provided by my co-supervising colleagues and me an exceptional social and economic impact. Vista Economics is the study of choice in situations with constrained budgets and uncertainty. Technology is largely regarded as a black box and seen as a major means to generate financial wealth. In technical sciences humans are regarded as developers and users of technology. Our heavy reliance on technical 'fixes' to manage issues, which objectively are mainly due to wrong choices, like excessive behaviour (overconsumption, overproduction and exhaustion of natural resources leading to climate change etc.) means that technological 'development' is frequently used as an escape route, because the political will to change behaviour is lacking and strong lobbies exist to maintain this detrimental behaviour. 'Let the polluter pay' is a basic and fairly effective principle in environmental economics. It may save tax payers large sums of money, yet it is frequently ignored. Instead, society spends large amounts on technology, which is great for engineers, but does it also solve society's challenges or does it create new, but different problems? About 12 years ago, I started specializing in logistics, learning on the job. There was a vision behind, of course. It started with the recognition that logistic decisions are in essence micro-economic decisions. Then there is a huge market, as the majority of the TIL students chooses a logistics specialisation. This also means that this field provides excellent cooperation with colleagues specialising in logistics. My actual scope is much broader than this field: Advanced logistics - operations, warehousing, SCM, (change) management & engineering; Sustainability and climate impact: operations & policy; Asset management and maintenance; Trucking logistics; Railway freight and passenger services & technology; Airport design & operations; Maritime transport and container handling; Transport~ and infrastructure policy and planning; Other transport and traffic (public transport, emerging technologies, scenario studies); Built environment (housing, well-being, environment); (Techno-)economic and financial decision-making (cba, business cases) in railway- and sanitary engineering; Topics in transport-economics, spatial-economics and economic geography.

Students Amos Yusuf, Mick Dam & Bas Brouwer winners of Mekel Prize 2024

Master students Amos Yusuf, from the ME faculty (Mick Dam, from the EEMCS faculty and graduate Bas Brouwer have won the Mekel Prize 2024 for the best extra scientific activity at TU Delft: the development of an initiative that brings master students into the classroom teaching sciences to the younger generations. The prize was ceremonially awarded by prof Tim van den Hagen on 13 November after the Van Hasselt Lecture at the Prinsenhof, Delft. They received a statue of Professor Jan Mekel and 1.500,- to spend on their project. Insights into climate change are being openly doubted. Funding for important educational efforts and research are being withdrawn. Short clips – so called “reels” – on Youtube and TikTok threaten to simplify complex political and social problems. AI fakes befuddle what is true and what is not. The voices of science that contribute to those discussion with modesty, careful argument and scepticism, are drowned in noise. This poses a threat for universities like TU Delft, who strive to increase student numbers, who benefit from diverse student populations and aim to pass on their knowledge and scientific virtues to the next generation. It is, therefore, alarming that student enrolments to Bachelor and Master Programs at TU Delft have declined in the past year. Students in front of the class The project is aimed to make the sciences more appealing to the next generation. They have identified the problem that students tend miss out on the opportunity of entering a higher education trajectory in the Beta sciences – because they have a wrong picture of such education. In their mind, they depict it as boring and dry. In his pilot lecture at the Stanislas VMBO in Delft, Amos Yusuf has successfully challenged this image. He shared his enthusiasm for the field of robotics and presented himself as a positive role model to the pupils. And in return the excitement of the high school students is palpable in the videos and pictures from the day. The spark of science fills their eyes. Bas Brouwer Mick Dam are the founders of NUVO – the platform that facilitates the engagement of Master Students in high school education in Delft Their efforts offer TU Delft Master Students a valuable learning moment: By sharing insights from their fields with pupils at high school in an educational setting, our students can find identify their own misunderstandings of their subject, learn to speak in front of non-scientific audiences and peak into education as a work field they themselves might not have considered. An extraordinary commitment According to the Mekel jury, the project scored well on all the criteria (risk mitigation, inclusiveness, transparency and societal relevance). However, it was the extraordinary commitment of Amos who was fully immersed during his Master Project and the efforts of Brouwer and Dam that brought together teaching and research which is integral to academic culture that made the project stand out. About the Mekel Prize The Mekel Prize will be awarded to the most socially responsible research project or extra-scientific activity (e.g. founding of an NGO or organization, an initiative or realization of an event or other impactful project) by an employee or group of employees of TU Delft – projects that showcase in an outstanding fashion that they have been committed from the beginning to relevant moral and societal values and have been aware of and tried to mitigate as much as possible in innovative ways the risks involved in their research. The award recognizes such efforts and wants to encourage the responsible development of science and technology at TU Delft in the future.

New catheter technology promises safer and more efficient treatment of blood vessels

Each year, more than 200 million catheters are used worldwide to treat vascular diseases, including heart disease and artery stenosis. When navigating into blood vessels, friction between the catheter and the vessel wall can cause major complications. With a new innovative catheter technology, Mostafa Atalla and colleagues can change the friction from having grip to completely slippery with the flick of a switch. Their design improves the safety and efficiency of endovascular procedures. The findings have been published in IEEE. Catheter with variable friction The prototype of the new catheter features advanced friction control modules to precisely control the friction between the catheter and the vessel wall. The friction is modulated via ultrasonic vibrations, which overpressure the thin fluid layer. This innovative variable friction technology makes it possible to switch between low friction for smooth navigation through the vessel and high friction for optimal stability during the procedure. In a proof-of-concept, Atalla and his team show that the prototype significantly reduces friction, averaging 60% on rigid surfaces and 11% on soft surfaces. Experiments on animal aortic tissue confirm the promising results of this technology and its potential for medical applications. Fully assembled catheters The researchers tested the prototype during friction experiments on different tissue types. They are also investigating how the technology can be applied to other procedures, such as bowel interventions.

A key solution to grid congestion

On behalf of the TU Delft PowerWeb Institute, researchers Kenneth Brunninx and Simon Tindemans are handing over a Position Paper to the Dutch Parliament on 14 November 2024, with a possible solution to the major grid capacity problems that are increasingly cropping up in the Netherlands. The Netherlands is unlikely to meet the 2030 climate targets, and one of the reasons for this is that large industry cannot switch to electricity fast enough, partly because of increasingly frequent problems around grid capacity and grid congestion. In all likelihood, those problems will actually increase this decade before they can decrease, the researchers argue. The solution offered by the TU Delft PowerWeb Institute researchers is the ‘flexible backstop’. With a flexible backstop, the current capacity of the power grid can be used more efficiently without sacrificing safety or reliability. A flexible backstop is a safety mechanism that automatically and quickly reduces the amount of electricity that an electric unit can draw from the grid (an electric charging station or a heat pump) or deliver (a PV installation). It is a small device connected or built into an electrical unit, such as a charging station or heat pump, that ‘communicates’ with the distribution network operator. In case of extreme stress on the network, the network operator sends a signal to the device to limit the amount of power. Germany recently introduced a similar system with electric charging stations. The backstop would be activated only in periods of acute congestion problems and could help prevent the last resort measure, which is cutting off electricity to users. ‘Upgrading the electricity network remains essential, but in practice it will take years. So there is a need for short-term solutions that can be integrated into long-term planning. We, the members of the TU Delft PowerWeb Institute, call on the government, network operators and regulator to explore the flexible backstop as an additional grid security measure,’ they said.
