On the spectral properties of square matrices that are strictly sign-regular of some order k (2018)
Alseidi, Rola ; Garloff, Jürgen
A matrix is called strictly sign-regular of order k (SSR_k) if all its k-by-k minors are nonzero and have the same sign. In this poster, the spectral properties of nonsingular matrices which are SSR_k for a specific value k are studied.

Promoting Renewable Energies in Tourism (2018)
Müller, Laura ; Rothstein, Benno
In tourism, energy demands are particularly high. Tourism facilities such as hotels require large amounts of electric and heating / cooling energy while their supply is usually still based on fossil energies. This research approach analyses the potential of promoting renewable energies in tourism. It focuses on a combined and hence highly efficient production of both electric and thermal energy by biogas plants on the one hand and its provision to local tourism facilities via short distance networks on the other. Considering regional resource availability as well as socio-economic aspects, it thus examines strengths, weaknesses, opportunities and threats that can arise from such a micro-cooperation. The research aim is to provide an actor-based, spatially transferable feasibility analysis.
