Analytic Bipedal Walking with Fused Angles and Corrective Actions in the Tilt Phase Space
Allgeuer, Philipp (2020-12-15)As humanoid robots start to move from research labs to workplace environments and homes, the topic of how they should best and most reliably locomote in the face of unknown disturbances will be a topic of increasing ... -
Appearance Preserving Rendering of Out-of-Core Polygon and NURBS Models
Guthe, Michael (2005)In Computer Aided Design (CAD) trimmed NURBS surfaces are widely used due to their flexibility. For rendering and simulation however, piecewise linear representations of these objects are required. A relatively new field ... -
Application and Development of Computational Methods for Ligand-Based Virtual Screening
Heikamp, Kathrin (2014-05-20)The detection of novel active compounds that are able to modulate the biological function of a target is the primary goal of drug discovery. Different screening methods are available to identify hit compounds having the ... -
An Approach for Collaborative Ontology Development in Distributed and Heterogeneous Environments
Halilaj, Lavdim (2019-01-25)The era of digitalization poses high demands on capturing and processing knowledge generated in everyday life in formal models. Ontologies provide common means for formal knowledge capturing and modeling for a universe of ... -
Approaching Partial Differential Equations with Physics-Driven Deep Learning
Wandel, Nils (2023-12-14)Partial Differential Equations (PDEs) play an important role in describing continuous physical systems such as fluids, air-flows, waves and many more. Thus, by solving these equations, one can simulate smoke and water ... -
Approximability of Combinatorial Optimization Problems on Power Law Networks
Gast, Mikael (2013-10-30)One of the central parts in the study of combinatorial optimization is to classify the NP-hard optimization problems in terms of their approximability. In this thesis we study the Minimum Vertex Cover (Min-VC) problem and ... -
Approximate Inference Applications to Representation Learning and Stochastic Processes Problems
Ojeda Marin, César Ali (2021-04-07)The present dissertation dwells in the development of inference algorithms and methodologies for the study of dynamical datasets. We developed techniques to analyze time-series datasets for point processes, switching ... -
Approximation Complexity of Optimization Problems: Structural Foundations and Steiner Tree Problems
Hauptmann, Mathias (2004)In this thesis we study the approximation complexity of the Steiner Tree Problem and related problems as well as foundations in structural complexity theory. The Steiner Tree Problem is one of the most fundamental problems ... -
Approximations for Hierarchical and Lower-Bounded Clustering and the Complexity of Minimum-Error Triangulation
Arutyunova, Anna (2024-03-28)Clustering deals with the problem of finding structures in data. Given a number k we search for a good partition of a set of data points into at most k sets, where the sets of the partition are called clusters. In the ... -
Articulated Human Pose Estimation in Unconstrained Images and Videos
Iqbal, Umar (2018-12-12)The understanding of the articulated human body pose is of great interest in many scenarios. While humans have an unmatched ability to effortlessly extract and interpret such information in any unconstrained environment, ... -
Audio Embeddings for Semi-Supervised Anomalous Sound Detection
Wilkinghoff, Kevin (2024-09-03)Detecting anomalous sounds is a difficult task: First, audio data is very high-dimensional and anomalous signal components are relatively subtle in relation to the entire acoustic scene. Furthermore, normal and anomalous ... -
Automated Optimization Methods for Scientific Workflows in e-Science Infrastructures
Holl, Sonja (2014-04-22)Scientific workflows have emerged as a key technology that assists scientists with the design, management, execution, sharing and reuse of in silico experiments. Workflow management systems simplify the management of ... -
Automated Source Extraction for the Next Generation of Neutral Hydrogen Surveys
Flöer, Lars (2015-12-23)This thesis is a first step to develop the necessary tools to automatically extract and parameterize sources from future HI surveys with ASKAP, WSRT/Apertif, and SKA.<br /> The current approach to large-scale HI surveys, ... -
Automatic Evaluation of Dialogue-Systems Using Neural-Network Methods
Nedelchev, Rostislav (2023-06-05)We usually interact with computers by means of specialized tools that are not as common as the language humans use. This has motivated researchers for already several decades to develop algorithms that enable interfacing ... -
Automatic Organization of Digital Music Documents: Sheet Music and Audio
Fremerey, Christian (2010-08-12)This thesis presents work towards automatic organization and synchronization of scanned sheet music and digitized audio recordings in the scenario of a digital music library. The organization targeted in the project of ... -
Automatic Reconstruction of Parametric, Volumetric Building Models from 3D Point Clouds
Ochmann, Sebastian Klaus (2019-05-02)Planning, construction, modification, and analysis of buildings requires means of representing a building's physical structure and related semantics in a meaningful way. With the rise of novel technologies and increasing ... -
Automating the Fact-Checking Task: Challenges and Directions
Nascimento Esteves da Silva, Diego (2019-07-30)In recent years, misinformation has caused widespread alarm and has become a global concern, given the negative impact placed on society, democratic institutions and even computing systems whose the primary objective is ... -
