21. Rosetta Observations of Plasma and Dust at Comet 67P
Sammanfattning : In-situ observations of cometary plasma are not made because they are easy. The historic ESA Rosetta mission was launched in 2004 and traversed space for ten years before arriving at comet 67P/Churyumov-Gerasimenko, which it studied in unprecedented detail for two years. LÄS MER
22. Planning and Control of Uncertain Cooperative Mobile Manipulator-Endowed Systems under Temporal Logic Tasks
Sammanfattning : Control and planning of multi-agent systems is an active and increasingly studied topic of research, with many practical applications such as rescue missions, security, surveillance, and transportation. This thesis addresses the planning and control of multi-agent systems under temporal logic tasks. LÄS MER
23. Advanced MEMS Technology for Terahertz Frequencies
Sammanfattning : With the development of terahertz (THz) technology, a variety of application demands are growing rapidly, such as high-rate communications, THz radars, environmental monitoring, medical imaging, and space exploration. However, the fabrication, integration, and packaging techniques for THz components and systems pose great challenges for a large-scale, cost-effective production. LÄS MER
24. Pores, inclusions and electromagnetic stirring : Topics from the continuous casting of steel
Sammanfattning : This thesis deals with two topics of relevance to the continuous casting of steel,in view of their importance as regards the quality of the final solidified structure.The first concerns the precipitation of gas pores and inclusions in the interden-dritic region of the solidifying metal.

25. Förvandlingar i vikingatidens djurornamentik : Del 1 : En multiperspektivisk studie om figurknoppspännen av Birkatyp
Sammanfattning : During the past 150 years, different generations of scholars have been approaching Scandinavian Animal Art with queries that were as multifaceted as the materials that they studied. The focal point of this study are Birka type brooches, which are best likened to interactive sculptures that change shape as the viewer changes perspective. LÄS MER
