Item type:Publication, Access status: without files , Entwurf von Systemen zur Kühlung von elektronischen Komponenten mit dynamischen LastenDer steigende Bedarf in der Wandlung elektrischer Energie führt zu einem wachsenden Markt für Leistungselektronik. In dieser Arbeit werden latente Wärmespeicher zur Kühlung von Leistungselektronik in einem Flüssigkühlkreislauf und mit dynamischen Lasten eingesetzt. Experimentelle Untersuchungen zeigen die Potentiale von latenten Wärmespeichern bei dynamischen Lasten hinsichtlich des Wärmemanagements. Neben einem verbesserten Temperaturverhalten, ist eine Massereduktion des Kühlsystems durch eine kleinere Auslegung der Pumpe möglich. Ein Beispiel zeigt dabei, dass eine Massereduktion der Pumpe von bis zu 23% möglich ist.Publicationtype: Doctoral Thesis127 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: with files , Engineering students' understanding of basic electric circuit concepts and the effect of qualitative worksheets(2020-10); This thesis investigates engineering students’ (mis)conceptions about electric circuit concepts. Several Tutorial worksheets (some revised, some newly developed) are found to help reduce specific misconceptions. The concept of the electric potential is discussed in the context of threshold concept theory and its use in reducing student misconceptions about voltage is investigated.Publicationtype: Doctoral Thesis689 3748 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: with files , Design, dynamics, and control of micro underwater vehicle systems for autonomous environmental exploration(2019); This dissertation covers exploration and monitoring of environmental fields with micro underwater vehicles (μAUVs). The design of an underactuated μAUV is presented. Moreover, control concepts are introduced for trajectory tracking and path following. Two methods for underwater self-localization are presented, which are suitable for μAUVs. The first approach is based on time delays of arrival of acoustic signals. The second approach exploits attenuation of electro-magnetic signals in water. Lastly, an information theoretic control method is developed, which allows a fleet of μAUVs to explore environmental fields. The method combines stochastic optimal control with Gaussian Markov random fields.Publicationtype: Doctoral Thesis555 1056 - Some of the metrics are blocked by yourconsent settings
