Sie wirken sich auf unsere geistige und k{\"o}rperliche Gesundheit aus. Da einige unserer Emotionen als „schlecht" oder „negativ" wahrgenommen werden, erlauben wir uns oft nicht, sie zu f{\"u}hlen, und wir unterdr{\"u}cken sie. Ziel dieses Projekts ist es, mithilfe von Fotografie und Grafik zu zeigen, wie man mit unangenehmen und so genannten „negativen" Emotionen umgehen kann. Der Schwerpunkt liegt gleichermaßen auf dem konzeptionellen und kreativen Teil. Dabei wurden ein Modell und wechselnde Farblichter verwendet, um die emotionalen Zust{\"a}nde einer Person darzustellen, die diese Transformation durchl{\"a}uft. Ein weiteres Ziel ist es, die Bedeutung eines bewussteren Umgangs mit unseren Emotionen zu betonen. Das Endmedium ist ein Fotobuch inkl. Piktogramme, die die f{\"u}nf Stadien repr{\"a}sentieren: Leiden, Bewusstsein, Konfrontation, Ausdruck und Akzeptanz.

These eigenvalues are derived from the scalar inverse scattering problem for an inhomogeneous material with a conductive boundary condition. The goal is to study how these eigenvalues depend on the material parameters in order to estimate the refractive index. The analytical questions we study are: deriving Faber-Krahn type lower bounds, the discreteness and limiting behavior of the transmission eigenvalues as the conductivity tends to infinity for a sign changing contrast. We also provide a numerical study of a new boundary integral equation for computing the eigenvalues. Lastly, using the limiting behavior we will numerically estimate the refractive index from the eigenvalues provided the conductivity is sufficiently large but unknown.}, language = {en} } @incollection{MoorkampPetersonUibel2022, author = {Moorkamp, Wilfried and Peterson, Leif Arne and Uibel, Thomas}, title = {Nachhaltige Holzbr{\"u}cken f{\"u}r Geh- und Radwege}, series = {Bauphysik Kalender 2022: Holzbau, 22.

Plant virus-like particles represent ideal nanoscaffolds for an extremely dense and precise immobilization of enzymes, due to their regular shape, high surface-to-volume ratio and high density of surface binding sites. In the present work, tobacco mosaic virus (TMV) particles were applied for the co-immobilization of penicillinase and urease onto the gate surface of a field-effect electrolyte-insulator-semiconductor capacitor (EISCAP) with a p-Si-SiO₂-Ta₂O₅ layer structure for the sequential detection of penicillin and urea. The TMV-assisted bi-enzyme EISCAP biosensor exhibited a high urea and penicillin sensitivity of 54 and 85 mV/dec, respectively, in the concentration range of 0.1-3 mM. For comparison, the characteristics of single-enzyme EISCAP biosensors modified with TMV particles immobilized with either penicillinase or urease were also investigated. The surface morphology of the TMV-modified Ta₂O₅-gate was analyzed by scanning electron microscopy. Additionally, the bi-enzyme EISCAP was applied to mimic an XOR (Exclusive OR) enzyme logic gate.}, language = {en} } @inproceedings{SchopenShabaniEschetal.2022, author = {Schopen, Oliver and Shabani, Bahman and Esch, Thomas and Kemper, Hans and Shah, Neel}, title = {Quantitative evaluation of health management designs for fuel cell systems in transport vehicles}, series = {2nd UNITED-SAIG International Conference Proceedings}, booktitle = {2nd UNITED-SAIG International Conference Proceedings}, editor = {Rahim, S.A. and As'arry, A. and Zuhri, M.Y.M. and Harmin, M.Y. and Rezali, K.A.M. and Hairuddin, A.A.}, pages = {1 -- 3}, year = {2022}, abstract = {Focusing on transport vehicles, mainly with regard to aviation applications, this paper presents compilation and subsequent quantitative evaluation of methods aimed at building an optimum integrated health management solution for fuel cell systems.

Such applications rely on the application of a static offset magnetic field, which is generated traditionally with an electromagnet. Such a setup requires a current source, as well as passive or active cooling strategies, which directly sets a limitation based on the portability aspect that is desired for point of care (POC) monitoring applications. In this work, a measurement head is introduced that involves the utilization of two ring-shaped permanent magnets to generate a static offset magnetic field. A steel cylinder in the ring bores homogenizes the field. By variation of the distance between the ring magnets and of the thickness of the steel cylinder, the magnitude of the magnetic field at the sample position can be adjusted. Furthermore, the measurement setup is compared to the electromagnet offset module based on measured signals and temperature behavior.}, language = {en} }
