researcher Maddalen Irigoien and Prof. George Weiss from Tel Aviv University visited project colleague Alan Valadez during his research stay at KIT (Karlsruhe Institute of Technology).

They were joined by a scientist from outside the project.

Everyone was very impressed by the local laboratory, which Alan could benefit from for his research for two months.

Many thanks to the "Real Time Systems for Energy Technologies" group at KIT:

Project EuroWindWakes starts: More accurate modeling of offshore wind energy wake effects in the North Sea
In the North Sea, dense installations of offshore wind farms are planned in several regions. The resulting wake effects of large offshore wind farm clusters are of great importance for the calculation of energy yields. Current models often only allow for an inaccurate representation of these effects...

Study on knowledge transfer: How the “Gollum effect” hinders research and careers
Data and findings are not always shared openly in science. Sometimes, researchers hoard those data and provide little to no access to colleagues from their field. These were the results of a survey of 563 researchers from 64 countries conducted by scientists at Martin Luther University Halle-Wittenb...

New paper by researcher Zhuo Xu on the robustness of a fluid-particle interaction system.

"A distinctive feature, not yet considered in the ISS literature, is that our system involves a free boundary. More precisely, the fluid is described by the viscous Burgers equation, and the motion of the particle obeys Newton second law. ... The proof is based on the construction of a Lyapunov functional derived from a special test function."

At the 2025 researcher Bouchra Elghazi explained the basic idea behind her mathematical research with a pen - by balancing it on her palm and talking about dynamical systems and controls in a very illustrative way.

The audience enjoyed her lively presentation and were encouraged by the remarks about studying mathematics.

Additionally, the 15 students from different schools had a conversation about studying / a career in mathematics with professor Birgit Jacob.

Several PhD students and supervisors from the project met at the Spring School on Theory and Applications of Port-Hamiltonian Systems (PHS2025) last week.

The PhD students presented and discussed posters of their work. The supervisors presented, too, and the project coordinator was also involved in the organisation.

How can a central server effectively use a limited reward budget to motivate distributed clients to cooperate?

*A Potential Game Perspective in Federated Learning* explores this multi-agent interaction and decision-making problem through economic and game-theoretic perspectives:

arxiv.org/abs/2411.11793




Useful e.g. to build data-driven floating wind turbine models from distributed data.

A plot of Average training effort s on the y-axis with reward factor lambda on the x-axis.
Fairly flat at the start, starting to curve upwards after lambda_1 until it reaches lambda*. Here, a curve towards a higher and again flat level of average training effort curve begins (curve begins after a jump to a higher level of average training effort at lambda*)

The first network meeting took place in November 2023 @utwente .

12 freshly hired Researchers (PhD students) and their supervisors plus a few more project participants met for the first time at the University of Twente.

After a day of meetings with lively discussions also during the breaks the day was concluded by a cozy dinner at the conference venue.

The Researchers stayed on for five additional days of learning.
