On the Trail of the Internet: An interactive scavenger hunt full of puzzles, discoveries, and exciting insights into the digital world. Participants embark on an exciting scavenger hunt through the building to uncover the secrets of the Internet. At various stations throughout the building, they’ll encounter tricky puzzles, hidden clues, and varied challenges that can only be solved through teamwork, logical thinking, and creativity.

The scavenger hunt is self-guided. The necessary materials will be distributed at the specified time; English versions are available upon request.

• Registration for material pickup at 11:00 a.m.
• Registration for material pickup at 1:00 p.m.

Materials will be distributed in the Column Hall at the Distributed Systems Division’s booth.

During a guided tour of the laboratories of the Department of Measurement Technology and the spin-off company Metubiq, you’ll gain fascinating insights into high-precision surface measurement technology and the development of innovative measuring instruments.

How do you measure structures that are a thousand times smaller than a human hair? On this lab tour, you’ll gain insight into the research and development work being conducted by the Department of Measurement Technology at the University of Kassel and the spin-off company Metubiq.

In the first part, you’ll visit the optics lab of the Department of Measurement Technology. There, you’ll be introduced to modern measurement methods for surface analysis. Through live demonstrations, you’ll experience various measuring instruments that achieve resolutions in the nanometer range—corresponding to a level of detail approximately 70,000 times finer than the thickness of a human hair.

In the second part, you’ll gain insight into the spin-off company Metubiq. The team will present its laboratory and manufacturing infrastructure and demonstrate how innovative measuring instruments for industrial applications are developed and manufactured based on university research.

Guided tour of the electrical and mechanical workshop. An overview of the activities and responsibilities of the University Workshops. Tour of the new services offered: drone operations and waterjet cutting.

The University Workshops offer technical expertise and comprehensive services, whether you teach, study, or work at the University of Kassel. Their mission is to support research and teaching at the University of Kassel, and they are available to all departments. The electrical workshop and a mechanical workshop are located at the Wilhelmshöher Allee campus.

Tour the workspaces with their many machines and tools and gain insight into exciting projects and activities. The new services—drones (electrical workshop) and waterjet cutting (mechanical workshop)—will be explained in detail using practical examples. Learn about processes, manufacturing options, and project management.

• Registration for the tour: 10:45–11:15 a.m.
• Registration for the tour from 11:45 a.m. to 12:15 p.m.
• Sign up for the tour from 1:30 p.m. to 2:00 p.m.

The tour begins in the Column Hall at the Uniwerkstätten information desk.

At the University of Kassel’s Wilhelmshöher Allee campus, interdisciplinary research into the electric mobility of tomorrow is being conducted in the departments of “Power Electronics,” “Vehicle Systems and Fundamentals of Electrical Engineering,” and “Mechatronics with a Focus on Vehicles.” Each department contributes to the bigger picture in accordance with its respective discipline. During this lab tour, you’ll learn through many practical examples about the research questions currently being addressed—including in collaboration with regional industry partners. The scope ranges from electrified historic vehicles (VW Beetles) to state-of-the-art electric truck axles.

• Registration for the tour: 11:00 a.m. – 12:00 p.m.
• Registration for the tour at 1:30–2:30 p.m.

The tour starts at the green electric Beetle next to Entrance C.

The Intelligent Embedded Systems research group investigates machine learning methods for systems that perceive, make decisions, and act in the real world. During the tour, you’ll gain insight into current research on machine learning. Two application areas will be presented that clearly illustrate this:

Station 1: DeepBirdDetect – AI Listens to Biodiversity
The decline in biodiversity can only be combated if it can be measured. In the DeepBirdDetect project, we are developing deep learning methods that automatically identify bird species based solely on their calls and songs. We’ll show how an audio recording is converted into a spectrogram and then used to identify a species, the role that explainable AI plays in this process, and how such models run directly in the field on small, energy-autonomous devices.

Station 2: Connected Driving—Vehicles and Road Infrastructure Working Together
A single vehicle can only ever see a small portion of its surroundings. This is exactly where cooperative perception comes into play. At this station, we’ll demonstrate both sides of this interaction: our research vehicle—a rolling laboratory that uses its sensors to capture the surroundings and process the data in real time—and the Roadside Unit, which monitors traffic from an elevated vantage point and shares its information with the vehicles. We’ll explain which sensors are in use, how vehicles and infrastructure communicate with each other, and why this ensures greater safety—especially in areas with limited visibility.

• Registration for the guided tour at 10:30

The tour starts in the colonnade at the Infopoint.

Comparison and ordering are among the most important methods for systematically exploring relationships between objects in (empirical) data. Compared to numerical approaches (such as those for measuring the similarity of objects), however, the number of methods for ordinal data has been limited to date. One reason for this is the limited availability of computational resources required for ordinal calculations during the last century. This talk will present new methods in the field of formal conceptual analysis that can be applied to ordinal data science. For example, how can one measure the degree of agreement or disagreement among travel guides in their ratings? And why has Croatia’s accession to the European Economic Area reduced the complexity of membership relationships with supranational institutions?

• Registration for the lecture: 1:30–2:30 p.m.

The lecture will take place in Lecture Hall 0315.
