A VR-based training system for an ankle surgery See

The supramalleolar osteotomy is a surgery, which aims to correct ankle osteoarthritis. Surgeons specializing in osteotomies regularly need to make accurate and precise cuts to a patient's bone with tools like an oscillating bone saw. In order to acquire the knowledge and skills ...

Simulation of muscle movements with GNNs See

In the last few years Graph Neural Networks (GNNs), a family of neural architectures used for irregularly structured data, gained a rising interest of the graph processing research community. Previous work has shown the potential of GNNs in simulations. In the field of bioinformati...

Quantifying and visualizing model similarities for multi-model methods See

Modeling environmental systems is typically limited by an incomplete system understanding due to scarce and imprecise measurements. This leads to different types of uncertainties, among which conceptual uncertainty plays a key role, but is difficult to address. Conceptual uncertainty refers to&#x...

Formal analysis of self-issued OpenID providers See

The Self-Issued OpenID Provider specification is an extension of OpenID Connect that allows users to authenticate at Relying Parties using an Identity Provider under the local control of the user. For this, the Self-Issued OpenID Provider specification introduces a notion of an identity...
