1. 21. On the Evolving Friction of Layered Materials and the Prospect of Their Image Reconstruction

   Författare :David Andersson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Sammanfattning : The scope of this licentiate thesis is twofold: 1. Investigate the frictional properties of systems with layered materials; 2. Employing image recognition algorithms to find the substrates in AFM experiments. LÄS MER

3. 22. Blind equalization using third-order moments

   Författare :Patrik Pääjärvi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Sammanfattning : The use of third-order moments in blind linear equalization has been studied with emphasis on their performance in on-line methods of low complexity. Blind equalization has widespread use in areas such as digital communications, acoustics, geophysical exploration, image processing and general measurement problems. LÄS MER

4. 23. Titania supported vanadium oxide catalysts in the NH3-SCR reaction: Effect of vanadium loading, promoters and aging

   Författare :Alexander Nellessen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nb; aging; Ce; infrared spectroscopy; VOx; NH3-SCR; vanadium oxide;

   Sammanfattning : Emissions of nitrogen oxides (NOx) from combustion processes in mobile sources attract significant attention due to their role as a major source of atmospheric contamination, along with health risks and environmental issues. Since combustion processes in heavy-duty vehicles are expected to be used for a foreseeable future, many efforts have been invested in a suitable deNOx technology. LÄS MER

5. 24. Turbulent and neoclassical transport in tokamak plasmas

   Författare :Istvan Pusztai; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

   Sammanfattning : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. LÄS MER

7. 25. Catalysis in Dynamic Systems: Control within Molecular Reaction Networks

   Författare :Fredrik Schaufelberger; Olof Ramström; Leonard Prins; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems chemistry; dynamic covalent chemistry; catalyst screening; reaction networks; organocatalysis; imine exchange; combinatorial chemistry; dynamic systemic resolution; feedback; error-correction; Morita-Baylis-Hillman reaction; C-H activation; H-bond catalysis; transamination; Kemi; Chemistry;

   Sammanfattning : Life as we know it is based on complex networks of biochemical reactions that constantly interact within large dynamic systems. The field of systems chemistry uses chemical models to study how reaction networks – and thereby life – function on a molecular level. LÄS MER
