How do artificial neural networks and the algorithms derived from them reach correct decisions? And how can this be understood? Gitta Kutyniok, a mathematician, explores the mystery of artificial intelligence.
How to reduce emissions in the transport sector while maintaining our mobility? "SynphOnie", a research cluster funded by the German Federal Ministry of Education and Research (BMBF) that includes a team of researchers from the University of Passau headed by Professor Tobias Harks, is developing a mathematical model of transport flows to help make transport planning both needs-based and sustainable.
Whether you need to go to work, the train station, the doctor's, the grocery store, or you want to visit family or go on a trip – outside of cities, such trips are often made by private vehicle. This is because there is usually not enough demand for large buses that would run a fixed route to maintain an economical operation. This gap is filled by so-called dial-a-bus services such as the "VGI-Flexi" service offered by the Ingolstadt transport association (VGI), which is being scientifically supported by logistics expert Prof. Dr. Pirmin Fontaine from the Catholic University of Eichstätt-Ingolstadt (KU).
Accurately modeling extreme precipitation events remains a major challenge for climate models. These models predict how the earth's climate may change over the course of decades and even centuries. To improve them especially with regard to extreme events, researchers now use machine learning methods otherwise applied to image generation.
Two tranregios at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have had their funding extended: the collaborative research center/transregio 154 “Mathematical modeling, simulation and optimization using the example of gas networks” is entering into its third funding period, whilst the CRC/transregio 241 “Immune-epithelial communication in inflammatory bowel diseases” has had its funding extended for the first time.
Major success for FAU researchers: The German Research Foundation (DFG) has approved funding for two new research training groups (RTG) in fall 2022 and has extended funding for an existing RTG. This means that the DFG is providing around 15.3 million euros of funding for young researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) who are completing doctoral degrees in the fields of linguistics, literature studies, and applied mathematics
Dr. Martin Weibelzahl is a post-doctoral researcher at the University of Bayreuth and, among others, leads the large-scale SynErgie project, which is funded by the Federal Ministry of Education and Research and focuses on the design of the German energy transition, at the Project Group Business & Information Systems Engineering of the Fraunhofer FIT. For his outstanding scientific achievements, Dr. Weibelzahl was honoured with the Young Researchers Award from the Gesellschaft für Operations Research e.V. (GOR). During an international conference organised by GOR, he received the award, endowed with € 2,000, on 1 September 2021, together with this year's two other winners.
A team at the Technical University of Munich (TUM) has designed and commissioned the production of a computer chip that implements post-quantum cryptography very efficiently. Such chips could provide protection against future hacker attacks using quantum computers. The researchers also incorporated hardware trojans in the chip in order to study methods for detecting this type of “malware from the chip factory”.
Low-achieving pupils benefit more in mathematics lessons from learning materials on tablet PCs than high-achieving children. They are obviously helped by individualized learning paths, immediate feedback and the hands-on processing of interactive content. This conclusion was reached in a study conducted by the Technical University of Munich (TUM) with sixth-grade students. The team of researchers has developed an eBook for learning fractions, which is available free of charge in English, Spanish and German.
Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers at the Technical University of Munich (TUM) have discovered a universal mathematical structure at these so-called tipping points. It creates the basis for a better understanding of the behavior of networked systems.
