Researchers at Graz University of Technology have developed a new measuring system that can monitor the static and dynamic condition of buildings using just a few antennas. From the outside, the Kölnbrein Dam in Carinthia, which is operated by Verbund and is Austria's highest dam, and the DC Tower in Vienna, Austria's highest building, do not have much in common, but for a research group led by Caroline Schönberger and Werner Lienhart from the Institute of Engineering Geodesy and Measurement Systems at TU Graz, they are of equal scientific interest.

Theoretical predictions of quantum field theory confirmed experimentally for the first time Innsbruck scientists led by Peter Zoller have developed a new tool for determining entanglement in many-particle systems and demonstrated it in an experiment. The method enables investigations of previously inaccessible physical phenomena and can contribute to a better understanding of quantum materials.

In the Christian Doppler Laboratory under his leadership, Franz Wotawa has developed test and monitoring procedures with company partner AVL that make common driver assistance systems safer. Intelligent Speed Assist, Emergency Brake Assist, Emergency Lane Keeping Assist, Driver Drowsiness Assist, Reversing Assist, Low Concentration Warning System or Emergency Brake Lights - from July 2024, a whole range of safety and driver assistance systems will be mandatory for all new cars in the European Union.

It is becoming increasingly easier to carry out calculations with quantum computers. However, calculations show that there are fundamental limits - namely the quality of the clock used. There are different ideas about how quantum computers could be built. But they all have one thing in common: you use a quantum physical system - for example individual atoms - and change their state by exposing them to very specific forces for a specific time.

By Falko Schoklitsch Researchers at TU Graz and the Helmholtz Centre for Information Security have identified a security vulnerability that could allow data on virtual machines with AMD processors to fall under the control of attackers. In the area of cloud computing, i.e. on-demand access to IT resources via the internet, so-called trusted execution environments (TEEs) play a major role.

Artificial intelligence (AI) is already widely used in medical diagnostics. An Austrian-Australian research team led by dermatologist Harald Kittler from MedUni Vienna investigated the extent to which diagnosis and therapy of pigmented skin lesions benefit from it in a realistic clinical scenario. In a study published by The Lancet Digital Health, the team compared the accuracy in diagnosis and therapy recommendation of two different algorithms in smartphone applications with that of doctors.

The "Data" working group headed by Oliver Kimberger, Professor of Perioperative Information Management at MedUni Vienna's Department of Anesthesiology, Intensive Care Medicine and Pain Medicine, conducted a study to investigate the influence of artificial intelligence on doctors' covid triage decisions.

Important security holes in modern Internet technology have been discovered by TU Wien (Vienna). Now the international IT community is working to close them. The Internet has undergone major technical changes in recent years, which has also led to new security problems. The IT security team at TU Wien (Vienna) analyzed security vulnerabilities that arise from the interaction of cookies and web frameworks - software packages that are often used today by web programmers to create websites.

By Birgit Baustädter Elisabeth Lex's research combines computer science methods with social science approaches, searching for clues to understand framing, polarisation and opinion clusters. More and more often, people are getting the feeling that society is increasingly polarised - regarding measures introduced during the Covid-19 pandemic, the question of vaccinations, elections, or environmental protection.

Researchers at TU Graz and the Helmholtz Center for Information Security have discovered a novel security gap in all common CPUs that can hardly be mitigated. Main processors (CPUs) of computers are designed to run multiple applications simultaneously. This is beneficial for efficiency, but poses a security risk.

A world record in solving satisfiability problems was achieved at the Vienna University of Technology - it is quite abstract, but the technology behind it is extremely important for hardware and software industries . Suppose Alice, Bob, and Carla answer a question. Each of the three answers is either correct or incorrect.

A quarter of a century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances which would open the door to the construction of a worldwide quantum information network. Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted quantum information over tens of kilometers.

An artificial intelligence developed at TU Wien (Vienna) can suggest appropriate treatment steps in cases of blood poisoning. The computer has already surpassed humans in this respect. In the future, artificial intelligence will play an important role in medicine. In diagnostics, successful tests have already been performed: for example, the computer can learn to categorise images with great accuracy according to whether they show pathological changes or not.

In quantum research, tailor-made electromagnetic fields are needed to precisely control particles. The TU Vienna has shown that machine learning is an excellent tool for this purpose . Tiny particles can be manipulated with electromagnetic fields: You can capture them, hold them, or move them to a specific location.

By Susanne Filzwieser In the new Christian Doppler Laboratory for Reliable Systems in Harsh Environments, researchers at TU Graz, supported by the refractories group RHI Magnesita, are focusing on data-driven condition monitoring in the steel production process. Things are heating up in steel production.
