The student initiative INSIGHT, operating at our Institute of Medical Engineering, introduces itself with an exciting project: Self-construction of a magnetic resonance tomograph for the desk. They broadcast live the assembly of the core piece, namely the magnet system for the small scanner. This is an assembly of iron yoke, pole pieces and two extremely strong neodymium permanent magnets. The assembly is relatively spectacular, as forces of up to one and a half tons act on the parts in the meantime and therefore great caution, some securing and some courage are required during assembly. The team of four students has been eagerly awaiting this moment for a year and wants to share the exciting scenes with all viewers. Live on YouTube: July 22th - 3pm

Computer models have been standard tools in basic biomedical research for many years. However, around 70 years after the first publication of an ion current model of a nerve cell by Hodgkin & Huxley in 1952, researchers at Graz University of Technology (TU Graz), in collaboration with the Medical University of Graz and the Memorial Sloan Kettering Cancer Center in New York, have finally succeeded in developing the world's first cancer cell model, thus launching "an essential tool for modern cancer research and drug development," reports a delighted Christian Baumgartner. The head of the Institute of Health Care Engineering with European Testing Center of Medical Devices at TU Graz is senior author of the publication in which the digital model is presented in the journal PLoS Computational Biology.

Biomechanist Gerhard Holzapfel can be pleased about two new science awards. His computer simulations are intended to facilitate medical prognoses.
Holzapfel can be pleased about another award. After the William Prager Medal (we reported in January), he received the next international medal: the Koiter Medal, awarded for special achievements in research and science. In addition to American scientists from renowned U.S. universities, Holzapfel is an Austrian among the list of award winners. "This is already a great honor," says the 60-year-old professor, who was already awarded the Erwin Schrödinger Prize ten years ago for his life's work.
Holzapfel's focus: the calculation of mechanical properties for vessel walls, such as an aorta or artery. He has developed his own model for this purpose. "You can map mechanical processes that happen in our body on the computer. The finer the model, the more accurate the prediction. On the virtual patient, you can thus predict what a medical intervention will be like," he explained to Kleine Zeitung. "We can make simulations that are very close to reality. That's where technology has advanced insanely."
Holzapfel began his career as a young postdoc at Stanford. "In America, there was already a lot of research going on in the field in the early 1990s, so I was there at the right time." In the meantime, he himself is the contact person for 200 students and drives countless projects forward. The TU Graz lead project "Aortic Dissection" has just been extended. This involves working on computer simulations of aortic dissections. An aortic dissection is a splitting of the wall layers of the aorta. This condition can be life-threatening. The aim of the TU project is to use algorithms and models to support diagnosis and treatment at an early stage.

New encryption methods ensure the pooling of sensitive income and health data at a very high level of data protection. It is precisely for such cases that research has developed technologies that are ripe for practical use.
In the course of the current discussion about a planned data registry for times of crisis such as pandemics, which is viewed critically by data protection experts, cybersecurity expert Christian Rechberger of Graz University of Technology takes notice: "Pandemic management using merged income and health data is very much possible with the required level of data protection. Together with international colleagues, we have developed new cryptographic methods since the beginning of the pandemic that will be used for such applications, among others."
Rechberger sees the crisis database as a classic case for the first use of the new technology. This is based on so-called homomorphic decryption: it allows confidential data to be processed and interleaved without first having to be decrypted. "This allows data registers to be implemented while maintaining privacy and protecting sensitive, personal data. No data source has to copy the data elsewhere, registers do not have to be merged centrally. The data remains local, and the calculations are encrypted. Only the result of the respective study is then disclosed."

Responsibility for the climate and the environment should not be assigned to the individual, emphasizes Gerald Schweiger. "This requires technological solutions at a systemic level." The fact that the 35-year-old, who conducts research on intelligent energy systems at the Graz University of Technology (TU), sometimes digresses into socially critical and philosophical considerations may be due to his education: "After HTL, I actually thought that technology wasn't for me after all, and initially followed up with studies in philosophy and social sciences. In the end, however, I only added another engineering degree and one in environmental systems science."
The result is not only a total of four academic degrees in the passport around his name in his passport (the fifth will follow soon), but also holistic demands such as these demands like this: "One less plastic bag is not a solution. We have to rethink entire systems and equip them with intelligence. Especially in the area of sustainability new insights have an enormous impact."
Gerald Schweiger (35) is concerned with energy systems of the future and their optimization with the help of physical models and artificial intelligence. He teaches at Graz University of Technology, where he heads the "Intelligent Energy Systems" research group, as well as at two Styrian universities of applied sciences. In addition, Schweiger leads several national and international projects on the topic.

Calculating probabilities, uncovering the value of X, analyzing graphs - math is a nightmare for some students.However, for students Maximilian Mallweger and Matthias Hülse rmath is passion. "Yes, it exists!" they write on their website Hellomath - the self-founded learning portal where students can prepare for the centralized math Matura.
The tasks that can be solved on Hellomath are taken from the official question pool of the Ministry and also from older maturity exams that are freely available. Maximilian has also created some tasks himself, based on basic competency schemes. Already 100 active users use the learning portal regularly.

As part of the GameOpSys research project, people were asked to document their own energy consumption using a study app. Researchers at TU Graz use this data for modeling and optimizing future energy systems.
The research group "Intelligente Energiesysteme und Cyber-Physical Systems" at the Institute of Software Technology at TU Graz is working on methods to make energy systems more efficient and intelligent, while also taking into account the interaction between humans and technology. In collaboration with simulation expert Niki Popper and his company dwh, the Graz-based research group led by Gerald Schweiger focused on necessary technologies for future user-centered energy services. For this purpose, a mobile app was developed that is intended to motivate users with game-like elements (gamification) to collect data on their own energy consumption (electricity, heating and cooling).

Denis Helic explains why Software development is much more than just programming. Software development does not only include programming skills, but also requires management and team leadership skills. User experience is also becoming increasingly important. The curricula are continuously updated and expanded via electives in order to respond to new developments. That's why the TU has offered an English-language bachelor's and master's degree in software engineering and management since 2005, where 20 percent consists management topics. Helic explains that the profession demands a range of soft skills, "from project management to teamwork to communication skills and much more." In addition, he says, today's students are tomorrow's company founders, designing and marketing their own products in the software field. This refutes the stereotype of the computer scientist tapping away in a lonely chamber.

Computer scientist Wolfgang Maass and his doctoral student Christoph Stöckl have found a new design method for artificial neural networks. These networks get by with extremely few signals. Similar to Morse code, they also give meaning to the pauses between the signals. Maass and Stöckl were inspired by the way the human brain works. The human brain processes several trillion calculations per second, but only needs about 20 watts to do so. This low energy consumption is made possible by inter-neuronal communication using very simple electrical impulses, so-called spikes. This research work is anchored at TU Graz in the Fields of Expertise "Human and Biotechnology" and "Information, Communication & Computing", two of five areas of strength at TU Graz.

Although treatment options are constantly improving, cardiovascular diseases are still one of the most frequent causes of death in Europe. The success of the treatment varies from patient to patient and depends on the individual pathology. Gernot Plank (Med Uni Graz) has now developed a computer model together with the mathematicians Gundolf Haase and Kristian Bredies from the University of Graz and computer scientist Thomas Pock from the Institute of Computer Graphics and Vision at Graz University of Technology, respectively, with which doctors can pre-simulate the optimal therapy and dramatically improve the success of treatment.
