Das in dieser Arbeit vorgestellte Gesamtkosten-Modell ermöglicht einen standortspezifischen Kostenvergleich anhand von 23 Einzelkostenpunkten. Die Kosten werden bis auf eine Struktur- bzw. Objektebene aufgelöst und die einzelnen Elemente separat als vereinfachte Modelle abgebildet. Die Granularität des Modells ...

Motivation: Biomineralization refers to microbially induced processes resulting in mineral formations. In addition to complex biomineral structures frequently formed by marine organisms, like corals or mussels, microbial activities may also indirectly induce mineralization. A famous example is the formatio...

Throughout the history of computer science, games have always been a major driving factor in the development of the artificial intelligence field. The pioneers of computer science have identified the importance of games like chess, checkers, and other similar games and have spent y...

Simulations of the coupled vehicle/guideway dynamics are an essential part in the development of high-speed magnetic levitation (maglev) systems with higher speed than traveled so far. In this contribution, a two-dimensional rigid multibody model mapping the heave-pitch motion of the vehicle...

This work gives an overview of a general approach for modeling the electromagnets of a magnetic levitation (Maglev) vehicle based on electromagnetic suspension. The method intends to map the magnets’ static and dynamic behavior in a frequency range relevant for use in mechatronic s...

Achilles tendon lengthening (ATL) is frequently used in the treatment of foot deformities. However, there is currently no objective method to determine the optimal muscle length during surgery. We developed an intraoperative approach to evaluate the passive and active forces of the tric...

These days, machine learning plays a key role in plenty of applications. Self-learning algorithms are developed in not only industrial applications, e.g., production lines, or fleet management, but also in the private sector, e.g. smart homes. The performance of these programs is signif...

While neural networks nowadays are widely used in different areas and applications, many usages of such neural networks are hindered by lacking computation power, especially on smaller devices like mobile devices. For this reason, it is very attractive to find ways to enable such&#...

Accurate automatic recognition of activities in various contexts is a topic of great interest in the research area of ubiquitous computing. Data-based and knowledge-driven approaches, or a mixture of both, have been developed in the recent years to achieve activity recognition in smart&...

We propose a hybrid detection approach for pitting detection in gears. Most research on pitting detection with machine learning is done on supervised data and often on simulated pitting. However, for pitting detection in practice an unsupervised approach is required. The main idea ...

This thesis aims to analyze the behavior of motorcyclists driving in a platoon through a simulation based on cellular automata theory. The relevant literature is reviewed to establish the basis for building the simulation, and the requirements for the simulation and model setup are...

Resistance training is known to increase physical and mental health but requires a lot of knowledge and experience to be done effectively and safely. Personal trainers and physiotherapists provide their knowledge to athletes but their profession requires a lot of learning and experience...

In dieser Arbeit wurden mehrere Materialien auf ihre Tauglichkeit für plasmonische Anwendungen untersucht. Dazu wurden Kammantennen aus Ge/GeSn sowie Nickel und Titan hergestellt und auf ihre Eignung als Pixel für thermographische Anwendungen untersucht. Zudem wurden Aluminium-Nanolochgitter hergestellt, w...

Materialmodelle, die sich zur Vorhersage des komplexen mechanischen Verhaltens von Thermoplasten in Crashsimulationen eignen, sind zwar seit einiger Zeit verfügbar, doch sehr aufwendig zu kalibrieren. Da viele ihrer Parameter nicht direkt in Versuchen gemessen werden können, erfolgt die Anpassung übli...

Bei einer Überfrequenz jenseits von 50,2 Hz müssen sämtliche Erzeugungsanlagen ihre in das Netz eingespeiste Wirkleistung reduzieren. In den zumeist resistiv geprägten Verteilungsnetzen der Mittel- und Niederspannung führt diese überfrequenzbedingte Leistungsreduktion zu einer lokalen Absenkung des Spannungsprofils....
