Rigidity in equivariant stable homotopy theory
Patchkoria, Irakli (2013-08-07)For any finite group G, we show that the 2-local G-equivariant stable homotopy category, indexed on a complete G-universe, has a unique equivariant model in the sense of Quillen model categories. This means that the ... -
RIMs and RIM interacting proteins: localization and function under physiological and pathophysiological conditions
Mittelstaedt, Tobias (2011-02-25)Neurons transmit signals to their target cells at specialized contact sites called synapses. At chemical synapses the signal propagation is mediated by the fusion of neurotransmitter filled synaptic vesicles with the ... -
Die Rindviehwirtschaft in den Agrarlandschaften des nördlichen Rheinlandes
Bohling, Günther (1959)Die vorliegende Arbeit will ein Beitrag sein zur Kenntnis der rheinischen Agrarlandschaften. Gegenüber der für die Erschließung agrarlandschaftlicher Eigenheiten üblichen Methode einer Gesamtschau der wirtschaftlichen ... -
RNA aptamers as selective protein kinase inhibitors: New molecular tools for the elucidation of signal transduction pathways
Lennarz, Sabine Michaela Irmgard (2015-04-16)Elucidating the precise function of individual protein kinases within complex signal transduction cascades represents one of the greatest challenges in molecular biology. Protein kinases are enzymes that catalyze the ... -
Robot navigation in cluttered environments
Regier, Peter (2022-01-11)Service robots are designed for non-industrial use to help people at home and in public spaces. Today, service robots perform a variety of tasks that range from distributing medical supply to clean the floor. The wide range ... -
Robot Navigation in Human Environments
Oßwald, Stefan (2019-01-16)For the near future, we envision service robots that will help us with everyday chores in home, office, and urban environments. These robots need to work in environments that were designed for humans and they have to ... -
Robust & Efficient Treatment of Industrial-Grade CAD Geometries for a Flat-Top Partition of Unity Method
Ziegenhagel, Albert (2022-12-15)Even today, the treatment of industrial-grade geometries is a huge challenge in the field of numerical simulations. The geometries that are created by computer aided design (CAD) are often very complex and contain many ... -
Robust and Interpretable Visual Perception Using Deep Neural Networks
Wagner, Jörg (2023-01-11)Autonomous vehicles promise to revolutionize the transportation of people and goods by increasing road safety, reducing resource consumption, and improving quality of life. To achieve an unrestricted and large-scale ... -
Robust Atomistic Modeling of Large Molecules by Efficient Force-Field and Tight-Binding Methods
Spicher, Sebastian (2021-11-17)Modern chemistry has almost no boundaries in elemental composition and molecular size. State-of-the-art chemical systems reach tremendous dimensions containing thousands of atoms, due to significant progress in the fields ... -
Robust Information Extraction From Unstructured Documents
Namysł, Marcin (2023-01-03)In computer science, robustness can be thought of as the ability of a system to handle erroneous or nonstandard input during execution. This thesis studies the robustness of the methods that extract structured information ... -
Robust Speech Recognition for German and Dialectal Broadcast Programmes
Stadtschnitzer, Michael (2018-10-25)Audio mining systems automatically analyse large amounts of heterogeneous media files such as television and radio programmes so that the analysed audio content can be efficiently searched for spoken words. Typically audio ... -
Robust Speech Recognition via Adaptation for German Oral History Interviews
Gref, Michael (2022-10-20)Automatic speech recognition systems often achieve remarkable performance when trained on thousands of hours of manually annotated and time-aligned speech. However, when applied in other conditions and domains than they ... -
Rock slope instability in alpine geomorphic systems, Switzerland
Meßenzehl, Karoline Christine (2018-04-26)Faced with the hazard potential and geomorphic importance of rock slopes adjusting to glacier retreat and current climate warming, the motivation of this dissertation is to increase our systemic and process understanding ... -
