1. 21. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods

   Författare :Bart Eduard Jan Pelssers; Jan Conrad; Jochen Schieck; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; direct detection; statistical analysis; fysik; Physics;

   Sammanfattning : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. LÄS MER

3. 22. Modeling and Control of a PMSynRel Drive for a Plug-InHybrid Electric Vehicle

   Författare :Shuang Zhao; Chandur Sadarangani; Sigurd Övrebö; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; feasible region; inductance spatial harmonics; integrated charger; permanent-magnet assisted synchronous reluctance machine; plug-in hybrid-electric vehicle; polarity detection; saturation and cross-saturation; sensorless control; signal injection; transient modeling.;

   Sammanfattning : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. LÄS MER

4. 23. Residual Generation Methods for Fault Diagnosis with Automotive Applications

   Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

   Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER

5. 24. Modeling and identification of nonlinear and impulsive systems

   Författare :Per Mattsson; Alexander Medvedev; Roy Smith; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear system identification; modeling; impulsive systems; impulse detection;

   Sammanfattning : Mathematical modeling of dynamical systems plays a central roll in science and engineering. This thesis is concerned with the process of finding a mathematical model, and it is divided into two parts - one that concentrates on nonlinear system identification and another one where an impulsive model of testosterone regulation is constructed and analyzed.

7. 25. Studies on the Differential Specificity of Protein Kinases and Its Applications

   Författare :Mart Loog; Bengt Jergil; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Protein kinases; protein kinase inhibitors; substrate specificity; peptide libraries; affinity chromatography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Protein kinases are enzymes that catalyse the phosphoryl transfer from the g-phosphate of ATP to acceptor amino acids in proteins. The specificity of selected model protein kinases was studied at three different levels using a) novel bi-substrate-analogue inhibitors, b) synthetic peptide substrates and c) mutated protein substrate analogues.
