How not to waste energy on 5G

Earl McCune is geared up to break a few long-held believes in the field of wireless communication

The impact of algorithms

In our age of technology algorithms have become more complex and more influential than ever before. And yet, because of their omnipresence, we are much less aware of them.

Towards a sensible digital society

Mathematics, electrical engineering and computer science are the foundation of modern technology: they form the basis for solutions to this century's major challenges. This creates not only opportunities but also responsibilities. "As engineers, we must be aware of the fact that the digital society does not exclusively bring benefits", warns Professor John Schmitz, Dean of the Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS). Mathematics, (micro)electronics and computer science: all technical systems and hardware – from medical equipment to aircraft – require a combination of these three elements. "Take your smartphone", Professor Schmitz explains. "It contains electronic switches – integrated circuits. Designing them requires mathematics. Consider Kirchhoff's laws, which state that the sum of the voltages at a node in such a circuit equals zero; the same applies to the resistance in a loop. Solving such equations for simple circuits is manageable, but one modern integrated circuit (or microchip) contains millions of these loops. To do that, you really need to know your mathematics". Smartphones now have 100,000 times the computing power of the computers that were used for the moon landing. This was made possible by the development of micro-electronics, which in turn influenced the development of mathematics and computer science. "In the past, mathematics required a great deal of analytical solving. Current computing power and numerical methods mean we can simply calculate it all. This offers unprecedented possibilities," notes Schmitz. "In addition, all sorts of things that used to require experimental demonstration can now be partly calculated; so we don't have to conduct as many expensive experiments". Mathematics, computer science and electronics reinforce each other in this way, and are the joint foundation of modern technology – a role that Schmitz wants to put in the spotlight. Healthcare One topic that does not immediately bring EEMCS to mind is healthcare. The use of stem cells to grow tissue on electronic chips (‘Organ on Chip’) now makes it possible to conduct highly specific studies of how medicines work, in order to develop personalised individual medication. In the Bio-Informatics and Pattern Recognition research group, researchers are applying advanced data analysis in order to be able to interpret and use the ever-expanding volume of biological data (e.g. from DNA sequencing). Great things are happening in the field of medical imaging as well. "Take MRI scanners, which cost millions because of the linear magnets they require. Although these magnets have been fully optimised over time, the best possible technology is not being used to process the signals into images", explains Schmitz. "A combination of simple magnets and sophisticated image processing can produce very good image quality. This makes the devices affordable for developing countries as well".

"A combination of simple magnets and sophisticated image processing can produce very good image quality. This makes the devices affordable for developing countries as well". However, even more information can be extracted from the more expensive scanners. "That kind of system generates a mountain of data, only a small portion of which is used in constructing two-dimensional images. By using symbols – glyphs – to represent this sea of data, computer-graphics techniques can be used to generate visual insight into all kinds of processes taking place in the tissue. The current systems can't do that. Of course, serious mathematics lies behind all this", says Schmitz. "It’s about how we visualise information in a way that humans can understand. Computer graphics could also be helpful in the cockpit, where pilots see so much data flash by that they can hardly make anything of it". Energy transition The energy transition has been called the greatest challenge of this century. According to Schmitz, this is no empty claim: "Worldwide, the majority of our energy still comes from fossil fuels. That has soon to change to 100% green energy, and electric energy will play an important role in the process". The generation of sustainable energy, the storage and conversion of energy, smart energy networks: the researchers at EEMCS are working on all the areas that will make this possible. The transition from centralised to decentralised generation and distribution will play a major role here: "Energy is increasingly becoming a two-way street. For example, locally generated energy can be delivered to the net or perhaps stored temporarily in car batteries. The network will also have to be able to cope with fluctuating supplies of solar and wind energy. We will soon be able to test exactly how that works in our new system-integration lab". Schmitz is referring to the Electrical Sustainable Power Lab (ESP Lab), a unique facility for research on the integration of all these new technologies into a single sustainable energy system. Blockchain While traditional customers are increasingly becoming ‘prosumers’ of energy, so the number of transactions is also increasing. Soon there will be questions to be answered, such as how do you charge for energy you have supplied to a neighbour. Blockchain technology – a new form of safe, distributed data storage – could be useful in this context. "Blockchain aims to generate digital confidence. That is quite an achievement in an age when our confidence in institutions is so often being undermined", argues Schmitz. How does it work? "Blockchain encrypts documents or data, and then it generates a unique code: a hash. This is done in such a way that the hash changes if something in the document changes. This means that any fraud is immediately revealed". Confidence in blockchain also has to do with the fact that the storage of each document is spread across the internet, thereby making fraud or theft virtually impossible. "Blockchain can be used for a large number of applications that currently require intermediaries, for example registering wills or taking out mortgages. It can also provide access to the financial world in areas where there are no banks", Schmitz points out. "It will soon be possible to use blockchain to arrange anything that now requires proof of identity". EEMCS is at the forefront of the development of blockchain technology. TU Delft is a founding member of the Dutch Blockchain Coalition, which is based on the campus. "All partners from society and industry are represented there: banks, government bodies, industry, notaries, insurance companies, knowledge institutions. It’s easier to interact with the field when it's so near". Education This community underpins the faculty’s aims in regard to its teaching duties. "We want to solve societal problems. This requires research, as well as engineers who are able to put that into practice. We train them, because engineers are needed in order to solve the world’s problems’, declares Schmitz. In his assessment, the teaching at TU Delft is in good shape. In a recent benchmark study by the Massachusetts Institute of Technology (MIT), TU Delft is ranked high amongst the world’s best universities of technology. "I would venture to say that the educational innovation at EEMCS is one reason that we are one of the top five in the world. The MIT report makes explicit mention of our Solar Energy MOOC and the 'blended-learning' approach in the teaching of maths." The latter project is PRIME: Project Innovation Mathematics Education. "We teach mathematics across the entire university, so we have to be able to explain it well to non-mathematics students". A combination of videos, interactive quizzes and online homework is intended to provide students with comprehensible preparation for the lectures and to improve their mathematical foundations. "We will also soon be starting a 'digital-skills' project, in which all students will learn the basic elements of programming", notes Schmitz. In addition to imparting mathematics and digital skills, the project will also make sure students – and scientists – consider the potential risks of the digital society. Risks "Digitisation has a major influence on society. When you go to a restaurant, everyone is sitting there looking at their screens. Although we could debate about whether that is good or bad, it does have a major impact on daily life", argues Schmitz. "On the other hand, some people today still do not have any connection to the internet. Do they no longer count? The government already makes it nearly impossible to do a tax return on paper". Social exclusion is only one of the risks. Schmitz explains, "We can have computers train themselves to recognise images. For example, the neural network recognises whiskers and decides that it’s seeing a cat. In time, it trains itself by adjusting a variety of weighting factors in the neural network. Although there have been no problems so far, these systems are sometimes so complicated that we no longer understand what they are doing". This could lead to potentially major dangers if, for example, we use the same systems to drive our cars, manage the stock market or arrive at medical diagnoses. We need to find ways to make deep learning and similar technologies more comprehensible. Otherwise, we could be heading for ‘Weapons of Math Destruction’, as the mathematician Cathy O’Neil describes in her book of the same name. In general, this is nothing new. "There are two sides to whatever we invent, good or bad", argues Schmitz. "As an engineer, it's important to make this visible, and therefore transparent". Digital society Until recently, this was uncharted territory. "These problems are on their way because the digital society is unstoppable. In fact, they are already here, although they are a relatively new issue. We need to be aware that these kinds of factors will be playing a role. This starts with the training of good engineers, and this means in education", observes Schmitz. Fortunately, we are not alone in this endeavour. For example, the ‘Digital Society’ programme of the Association of Universities in the Netherlands (VSNU) addresses both the opportunities and the risks. "The universities are united in saying, 'We are facing a common task'. Where is the human factor in the digital society? To what extent can we trust digital contacts and transactions? Even if we do not yet have the answers, I have high expectations that we will be able to find them if we all work together. This is how we can progress together towards a responsible digital society". More information You can view the inaugural speech of Prof. John Schmitz on demand via ths link .

Green ammonia remains a challenge, but researchers make significant progress

The production of ammonia, essential for fertiliser production, is responsible for almost 1.5% of global carbon emissions. This needs to be greener, which is why researchers have been looking for sustainable alternatives for years.

NWO funding for flexible power demand in electrically driven industry

NWO is funding two projects to explore ways to make the power demand of industry more flexible, allowing it to better align with future energy supplies. One of these projects, “DEFLAME,” is led by Machteld van den Broek from TU Delft. Solar and wind power generate variable amounts of electricity, while today’s industry demands a relatively constant supply. Adjustments are needed to prepare industry for a power supply based on sun and wind. These adjustments include technical, economic, and social adaptations that are being researched collaboratively by academic institutions and industry partners in these two projects. They also aim to address the barriers that hinder such adaptations. About DEFLAME DEFLAME stands for Direct Electrification of Industrial Heat Demand supported by Flexibility at Multiple Levels and their Exchanges (DEFLAME). This project aims to make the Dutch process industry—particularly the chemical and food industries—more resilient and climate-neutral by electrifying industrial heat using flexible solutions. Van den Broek explains, “For instance, we could scale installations up or down, store heat in underground systems, and/or store electricity in batteries, so that industry can better respond to fluctuations in the energy network.” This effort requires collaboration across multiple levels: technology, individual plants, industrial clusters, and national and international energy systems. DEFLAME focuses on removing obstacles to electrifying low-temperature heat (up to 400°C) with efficient technology. “This kind of heat is used in many processes. It’s essential to drive the right chemical reactions, and it’s also needed for drying, distillation, and evaporation processes. For example, in the crystallisation process to turn sugar beets into sugar, or in salt extraction,” Van den Broek explains. In crystallisation processes, for instance, mechanical vapour recompression can be used. In this process, vapours are compressed by an electrically driven compressor and then reused to heat the evaporator. “This saves energy, as it uses residual heat and allows for electricity to be sourced cleanly. With solar and wind, unlike with gas, the power supply is variable. If we want to electrify industry, businesses and technology need to be able to respond flexibly to this, for example, by storing heat as a cluster or building flexibility into the electrical system.” DEFLAME will identify strategies and institutional arrangements to unlock these solutions from multiple levels and with an interdisciplinary approach. Van den Broek states, “I look forward to taking an important step together with our partners to advance industrial electrification in the Netherlands. This is an essential part of the energy transition.” Consortium Partners The consortium partners include Atlas Copco, Cosun, ISPT, Nobian, Oranje Wind Power II C.V./RWE, Smart Port, Stedin, Tennet, TNO, TU Delft, and TU Eindhoven.

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.

Design and imagination as essential tools during the climate crisis

In Nature Partner Journals, ten researchers advocate the use of imagination in tackling the climate crisis. They focus specifically on urbanising river deltas, which are of great social and economic importance and highly vulnerable to climate change. "We scientists should not merely outline doomsday scenarios," says Professor Chris Zevenbergen. "Create a vision for people to believe in and work towards.”
