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 3754 - 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 Thesis557 1063
