1. 1. Control of Wave Energy Converters in arrays

   Författare :Simon Thomas; Jens Engström; Mikael Eriksson; Jan Isberg; Erland Strömstedt; Axel Bochert; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : One way to lower the levelized cost of energy for wave power plants and paving so the way for commercial success, is to increase the power absorption by use of advanced control algorithms. This thesis investigates the influence of the generator inertia, the generator damping and the layout on power absorption and presents a new model free strategy of controlling wave energy converters.

3. 2. Estimation of Nonlinear Dynamic Systems : Theory and Applications

   Författare :Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

   Sammanfattning : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. LÄS MER

4. 3. Autonomous Åland : A hundred years of borderwork in the Baltic Sea

   Författare :Ida Hughes Tidlund; Simon Ekström; Barbro Blehr; Thomas M. Wilson; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Åland; Finland; borders; borderwork; built place; practico-inert; hodological navigation; maritime; minority; territorial autonomy; Ethnology; etnologi;

   Sammanfattning : This dissertation applies an ethnological and long-temporal view of borders. The region of Åland, being an autonomous and demilitarised island territory under Finnish sovereignty, serves as an illuminative case of the work that goes into keeping borders fixed for two reasons.

5. 4. Relational creativity : what can participatory art do for higher education?

   Författare :Sol Morén; Simon Lindgren; Thomas von Wachenfeldt; Fernando Hernádez-Hernández; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; creativity; relational creativity; higher education; participatory art; visual arts; fine arts; arts-based research; participatory design; design for learning; sociotechnical design; educational design research; future education; rethinking education; sustainable development;

   Sammanfattning : Why research creativity in higher education? Creativity is regarded as a key competence for future education by the European Union as well as by UNESCO, and my wish is to contribute to this contemporary global agenda of rethinking education. Creativity is central for complex problem- solving and we need to rethink education to facilitate for our future citizens to develop creativity, to be able to meet our interconnected world's urgent need for sustainable development.

7. 5. Modeling of Magnetic Fields and Extended Objects for Localization Applications

   Författare :Niklas Wahlström; Fredrik Gustafsson; Thomas B. Schön; Simon Maskell; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localization; magnetic tracking; extended target tracking; signal processing; machine learning; Gaussian processes; deep dynamical model; discretization;

   Sammanfattning : The level of automation in our society is ever increasing. Technologies like self-driving cars, virtual reality, and fully autonomous robots, which all were unimaginable a few decades ago, are realizable today, and will become standard consumer products in the future. LÄS MER
