  2. 21. Quantitative Tracer Based MRI Perfusion : Potentials and Limitations

    Author : Arvid Morell; Atle Bjørnerud; Håkan Ahlström; Linda Knutsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Perfusion; Contrast agent; Relaxivity; Radiology; Radiologi;

    Abstract : Tracer based MRI perfusion measurements is a clinically useful tool to assess regional distributions of tissue blood flow and volume. The method may be based on any of the three relaxation mechanisms T1, T1 and T2*, the latter denoted DSC-MRI being the most common. READ MORE

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

    Author : Alexander Nellessen; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 23. Turbulent and neoclassical transport in tokamak plasmas

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

    Abstract : 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. READ MORE

  6. 24. Blind equalization using third-order moments

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

    Abstract : 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. READ MORE

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

    Author : Fredrik Schaufelberger; Olof Ramström; Leonard Prins; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE
