2. 1. Situation awareness in pervasive computing systems : reasoning, verification, prediction

   Author : Andrey Boytsov; Christian Becker; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; situation awareness; context awareness; pervasive computing; ubiquitous computing; context prediction; Pervasive Mobile Computing; Distribuerade datorsystem;

   Abstract : The paradigm of pervasive computing aims to integrate the computing technologies in a graceful and transparent manner, and make computing solutions available anywhere and at any time. Different aspects of pervasive computing, like smart homes, smart offices, social networks, micromarketing applications, PDAs are becoming a part of everyday life. READ MORE

4. 2. Modeling of Wind Turbines for Power System Studies

   Author : Tomas Petru; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flicker; fault response; power quality; wind turbine; power system stability; measurements; prediction; verification; grid simulation; modeling;

   Abstract : The power quality impact of wind turbines on the electric grid and the response of the wind turbines to faults in the electric grid are investigated in this thesis. A detailed model of a stall-regulated, fixed-speed wind turbine system capable of predicting the flicker impact on the connected grid is presented and compared with field measurements. READ MORE

5. 3. EMC barriers : measurement methodologies and model verification

   Author : Urban Lundgren; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

   Abstract : The subject of Electromagnetic Compatibility (EMC) is introduced. A short overview of the regulatory EMC requirements in Europe and in the United States is presented. An explanation is given why it is important for people in the electronics business to understand the need for EMC regulations. READ MORE

6. 4. The fate and effect of pharmaceuticals in boreal surface waters

   Author : Johan Fahlman; Jonatan Klaminder; Jan Karlsson; Fredrik Jutfelt; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquatic ecosystems; behavioural effects; ecotoxicology; acoustic telemetry; field verification; social network; ekotoxikologi; Ecotoxicology; environmental science; miljövetenskap;

   Abstract : Traces of pharmaceuticals are often found in streams, rivers, and lakes as the result of effluent water discharge. This dissertation aims to create a better understanding of the fate of drugs in aquatic ecosystems and how oxazepam, an anxiolytic pharmaceutical commonly detected in surface waters, affects the behavior of perch (Perca fluviatilis).

7. 5. MRI evaluation and image processing in gel dosimetry. A study of selected MRI properties and image processing in 3D gel dosimetry

   Author : Peter Magnusson; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; image registering; multi-slice; slice profile; ferrous sulphate; polyacrylamide; 3D volume acquisition; RF field; B1 field; relaxation time; T1; T2; spin-echo; multi-spin-echo; stochastic noise; nonuniformity; SNR; radiologi; tomografi; medicinsk instrumentering; Radiopharmaceutical technology; Radiofarmaceutisk teknik; Physics; Fysik;

   Abstract : Gel dosimetry is a new dosimetry method applied in radiation therapy. Gel dosimeters consist of a radiation sensitive gel, which can integrate absorbed doses from several radiation sources or beams. The dose to the gel can be evaluated by magnetic resonance imaging (MRI), a procedure that is the focus of the present thesis. READ MORE
