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 numerical upscaling of elliptic multiscale problems at high contrast
Peterseim, Daniel; Scheichl, Robert (2016-01)We present a new approach to the numerical upscaling for elliptic problems with rough diffusion coefficient at high contrast. It is based on the localizable orthogonal decomposition of <em>H<sup>1</sup></em> into the image ... -
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 ... -
Rockglacier kinematics in a high mountain geosystem
Roer, Isabelle (2005)The study presents a regional approach for the quantification of rockglacier creep in a high mountain geosystem (Turtmann valley, Swiss Alps).<br /> By a combination of different methods, rockglacier movements were analysed ... -
Rockglacier Kinematics in a High Mountain Geosystem
Roer, Isabelle (2007)The study presents a regional approach for the quantification of rockglacier creep in a high mountain geosystem (Turtmann valley, Swiss Alps). <br /> By a combination of different methods, rockglacier movements were ... -
The role of ALDH in drought stress: A comparative analysis in A. thaliana and barley
Nasr Mahmoud, Abdelaziz Mohamed (2022-07-21)The work was divided into 3 major parts. The first part is studying the effect of ALDH enzymes on the redox homeostasis during oxidative stress, and the role of ALDHs during the germination, and longevity of A. thaliana ... -
The Role of Acyl-ACP Thioesterases and Glycerophosphodiester Phosphodiesterases for Gametophyte Development in Arabidopsis thaliana
Siebers, Meike (2016-08-09)Chloroplasts are the site of the <em>de novo</em> synthesis of the predominant proportion of fatty acids in plant cells. The growing fatty acid chain is bound to acyl carrier protein (ACP) during synthesis. Acyl-ACP ... -
A role of Alzheimer’s disease-associated γ-secretase in lipid metabolism and lipid droplet formation via LXR activation
Gutierrez, Esteban (2021-06-29)The γ secretase is an intramembrane protease complex, essential for the processing of a wide variety of type-1 membrane proteins. Among these is the amyloid precursor protein (APP), a protein strongly linked to Alzheimer’s ... -
Role of antimicrobial peptides in metabolism and innate immunity in Drosophila melanogaster
Varma, Disha (2014-08-12)“Metabolism” and “Immunity” are two essential, recognized and independent functions of animal kingdom. They have their own biological cycle independent of each other. While metabolism contributes, amongst other things, to ... -
The Role of Apoptosis Inducing Factor In modulating mtDNA copy number
Meyer, Katharina (2015-06-03)Mitochondrial DNA (mtDNA) encodes essential components of the mitochondrial electron transport chain. Depletion and mutations of mtDNA cause mitochondrial dysfunctions resulting in numerous human diseases, including ... -
