2. 6. Advanced MRI Data Processing

   Author : Joakim Rydell; Magnus Borga; Hans Knutsson; Göran Starck; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging MRI ; functional Magnetic Resonance Imaging fMRI ; spatial filtering; robust correlation estimation; correcting artifacts; Medical informatics; Medicinsk informatik;

   Abstract : Magnetic resonance imaging (MRI) is a very versatile imaging modality which can be used to acquire several different types of images. Some examples include anatomical images, images showing local brain activation and images depicting different types of pathologies. READ MORE

4. 7. Electron energization in near-Earth space : Studies of kinetic scales using multi-spacecraft data

   Author : Elin Eriksson; Andris Vaivads; Masahiro Hoshino; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic reconnection; electron acceleration; electron heating; magnetosheath; magnetotail; magnetic nulls; Cluster; Magnetospheric MultiScale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

   Abstract : Plasma, a gas of charged particles exhibiting collective behavior, is everywhere in the Universe. The heating of plasma to millions of degrees and acceleration of charged particles to very high energies has been observed in many astrophysical environments. How and where the heating and acceleration occur is in many cases unclear. READ MORE

5. 8. Processing and analysis of NMR data : Impurity determination and metabolic profiling

   Author : Jenny Forshed; Sven P. Jacobsson; Jules L. Griffin; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantitative nuclear magnetic resonance spectrometry; qNMR; multivariate analysis; peak alignment; data fusion; Analytical chemistry; Analytisk kemi;

   Abstract : This thesis describes the use of nuclear magnetic resonance (NMR) spectrometry as an analytical tool. The theory of NMR spectroscopy in general and quantitative NMR spectrometry (qNMR) in particular is described and the instrumental properties and parameter setups for qNMR measurements are discussed.
