Manipulating fragile objects of different shapes is a major robotics challenge. This led to the development and investigation of various gripper concepts with different flexible materials. This concept study focuses on the development of a shape-adaptive gripper that uses additively manufactured cylinders with variable heights and Shore hardness to achieve optimal adaptability and gripping...
Small and medium-sized enterprises (SMEs) are the backbone of many economies, particularly in Germany, where the Mittelstand plays a central role in employment and value creation. Yet, SMEs often operate under significant resource constraints, making them particularly vulnerable in times of external disruption. Starting with Covid-19, the convergence of global crises—such as geopolitical...
As a first-year doctoral researcher at the Offenburg University of Applied Sciences, I would like to present the concept and structure of my PhD thesis. The aim of my research is to develop a comprehensive framework to analyze the integration of hydrogen infrastructure into regional energy systems. This topic is particularly relevant given the technical and economic challenges posed by the...
In nickel-based superalloy components operating at high temperatures, such as rotor disks in aero engines, intergranular cracking can be a critical failure mode. The accelerated crack propagation along grain boundaries is driven by the combined effects of fatigue and oxygen diffusion and is described as dynamic embrittlement. The damage mechanism is highly depending on the characterisitics of...
Duplex steels (DS) combine the excellent mechanical properties of ferrite with the corrosion resistance of austenite and are used for components exposed to fatigue loading, such as offshore equipment. The cyclic behavior of DS is influenced by the properties of the two phases, their volume fractions, and their crystallographic orientations, which lead to varying degrees of incompatibility in...

Flexibel, klimafreundlich, unterschätzt: Pyrolyse als Schlüsseltechnologie bis 2050
Deutschland verfolgt das ambitionierte Ziel, bis 2045 klimaneutral zu werden. Dabei wird deutlich, dass neben der umfangreichen Reduktion von Treibhausgasemissionen auch Technologien zur Entfernung von CO₂ aus der Atmosphäre, sogenannte Negative Emission...
This presentation introduces a systematic approach to predict and prevent potential failures in AI-generated solution concepts for sustainable process innovation. Based on a paper prepared for the ICED 2025 Conference (to be presented in UT Dallas, 11–14 August 2025), the approach builds upon previous research combining generative AI with patent-based evaluation to identify secondary problems...
Chitin is one of the most abundant biopolymers on our planet, second only to cellulose. It can be found in the exoskeletons of crustaceans and insects, rendering it a readily available resource. Furthermore, the use of edible insects as a food source for humans has emerged as an issue of worldwide interest, due to global population growth, food insecurity in some regions of the world and...
As a first-year doctoral researcher, I would like to present the concept and structure of my PhD thesis, which explores the interactions between hydrogen deployment and negative emission technologies (NETs) in the energy system.
The core hypothesis of my research is that deploying NETs, specifically Bioenergy with Carbon Capture and Storage (BECCS) and pyrolysis, can offer a more...
Vision Language Models (VLMs) represent a major advancement in multi-modal Artificial Intelligence, combining visual and textual data processing. However, VLMs have mainly a knowledge about public available data. The Retrieval Augmented Generation (RAG) approach enhances access to external information.
In this talk, a Visual RAG Pipeline that merges the RAG approach with VLMs is presented....
Our research group focuses on investigation of spatial hearing in asymmetrical hearing losses that are treated with different hearing provisions in both ears. For example, when a hearing aid is used in conjunction with a normal hearing ear or a cochlear implant. Our results show that precise interaural alignment in the temporal and spectral domain is necessary to improve spatial hearing. In...
Formgedächtnislegierungen (FGL) bieten durch ihre kompakte Bauweise und hohe Energiedichte eine vielversprechende Alternative zu klassischen Antriebssystemen – insbesondere in der Robotik und bei miniaturisierten Greifern. Ihre Schlüssel¬eigenschaft ist eine reversible Phasenumwandlung, die kontrollierte Bewegungen ohne komplexe Mechanik ermöglicht.
In diesem Vortrag wird ein innovativer...
What biomechanics reveal about sprint endurance
What makes a successful 400-metre sprinter? Is it stride length, acceleration, stamina - or all of the above? In my doctoral project, I am looking for biomechanical characteristics that can explain performance in the long sprint.
I am particularly interested in an area that has been little studied to date: sprint endurance - the ability to...
