  2. 11. Multidimensional magnetic resonance imaging : new methods for analysis of cardiovascular dynamics

    Author : Lars Wigström; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Cardiovascular flow and motion occur in three-dimensional (3D) space and vary dynamically over the cardiac cycle. The description of these complicated patterns using non-invasive imaging requires new tools for data acquisition, processing and visualization. READ MORE

  4. 12. Imaging surface plasmon resonance

    Author : Olof Andersson; Bo Liedberg; Fredrik Björefors; Thomas Ederth; Jiří Homola; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : The central theme of this thesis is the use of imaging Surface Plasmon Resonance (iSPR) as a tool in the characterization of surfaces with laterally varying properties. Within the scope of this work, an instrument for iSPR analysis was designed and built. READ MORE

  6. 14. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes

    Author : Lina Carlbom; Håkan Ahlström; Olle Korsgren; Olof Eriksson; Lars Johansson; Tove Grönroos; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; Magnetic resonance imaging; Magnetic resonance spectroscopy; Type 1 diabetes; Type 2 diabetes; PET MR; Pancreas transplantation; Perfusion; Radiology; Radiologi;

    Abstract : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. READ MORE

  7. 15. Stochastic Resonance and Noise-Assisted Signal Transfer : On Coupling Effects of Stochastic Resonators and Spectral Optimization of Fluctuations in Random Network Switches

    Author : Peter Hammerstein; Claes Granqvist; Laszlo Kish; Hans Liljenström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; stochastic resonance; nonlinear stochastic dynamics; noise and fluctuations; magnetic domains; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Recent research shows that noise or random fluctuations must not always be destructive in Nature by degrading system performance. On the contrary, in nonlinear systems they can synchronize systems or enhance the quality of signal transmission. The latter possibility is reported in the thesis. READ MORE
