1. 21. Metamodeling for ultra-fast parameter estimation : Theory and evaluation of use in real-time diagnosis of diffuse liver disease

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Martin Gollvik; [2014]
   Keywords : Systems biology; diffuse liver disease; DLD; metamodeling; parameter estimation; MRI;

   Abstract : Diffuse liver disease is a growing problem and a major cause of death worldwide. In the final stages the treatment often involves liver resection or transplant and in deciding what course of action is to be taken it is crucial to have a correct assessment of the function of the liver.

3. 22. Study of the Optical Properties of sp2-Hybridized Boron Nitride

   University essay from Linköpings universitet/Tillämpad optik

   Author : Eduardo Antunez de Mayolo; [2014]
   Keywords : Spectroscopic ellipsometry; boron nitride; optical properties; materials characterization; III-V nitride semiconductors; cathodoluminescence; electron microscopy; Raman spectroscopy;

   Abstract : Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.

4. 23. The Point-Split Method and the Linking Number of Space Curves

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Timmy Forsberg; [2014]
   Keywords : Links; The Linking Number; Gauss Linking number; Point-split method; point-splitting; White s formula; C ̆alug ̆areanu; Calugareanu s relation; Twist; Writhe; twisting; Writhing;

   Abstract : This is a report on research done in the field of mathematical physics. It is an investigation of the concept of the linking number between two simple and closed spatial curves. The linking number is a topological invariant with scientific applications ranging from DNA biology to Topological Quantum Field Theory. READ MORE

5. 24. A measurement system for static non-linearities

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : Hanbing Xu; Kailin Hou; [2013]
   Keywords : Hanbing Kailin non-linearities;

   Abstract : Measuring static nonlinearities systems has been a hot topic in recent years. In this thesis, amplifier is a device as a static nonlinearities system. In most cases, amplifiers operate as a linear device under small signal conditions. However it becomes more nonlinear and distorting with increasing drive levels. READ MORE

6. 25. Improving the Modeling Framework for DCE-MRI Data in Hepatic Function Evaluation

   University essay from Institutionen för medicin och hälsa; Hälsouniversitetet

   Author : Anneli Mossberg; [2013]
   Keywords : DCE-MRI; modeling; irregular sampling; spatio-temporal standard deviation estimation; sampling time optimization; regional optimization; liver function evaluation; systems biology;

   Abstract : Background Mathematical modeling combined with prior knowledge of the pharmacokinetics of the liver specific contrast agent Gd-EOB-DTPA has the potential to extract more information from Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI) data than previously possible. The ultimate goal of that work is to create a liver model that can describe DCE-MRI data well enough to be used as a diagnostic tool in liver function evaluation. READ MORE
