21. Efficient Simulation of Wave Phenomena
Sammanfattning : Wave phenomena appear in many fields of science such as acoustics, geophysics, and quantum mechanics. They can often be described by partial differential equations (PDEs). As PDEs typically are too difficult to solve by hand, the only option is to compute approximate solutions by implementing numerical methods on computers. LÄS MER
22. Miniaturized Techniques for Protein Analysis
Sammanfattning : Proteins are a highly diversified group of molecules, andfor their study, advanced analytical tools are required. Inparticular, a need for high-throughput techniques has emergedin order to enable the characterization of large sets ofproteins. LÄS MER
23. Finite Difference Methods for Wave Dominated Problems
Sammanfattning : Wave models are an important class of models that describe many diverse phenomena such as sound waves, fluid flow, and quantum mechanics. These models are often described mathematically as partial differential equations (PDE). Often these equations do not admit solutions on closed-form and then the only option to study them is numerical methods. LÄS MER
24. Acute pancreatitis. With special reference to the activation peptide from carboxypeptidase B (CAPAP) as a predictor of severity
Sammanfattning : There is a wide range in the reported annual incidence of acute pancreatitis (AP). A minority of these patients develop a severe disease characterised by a high mortality and morbidity. In order to improve the outcome for patients with an attack of severe AP it is important to identify these patients early in the course of disease. LÄS MER
25. High-order finite element methods for incompressible variable density flow
Sammanfattning : The simulation of fluid flow is a challenging and important problem in science and engineering. This thesis primarily focuses on developing finite element methods for simulating subsonic two-phase flows with varying densities, described by the variable density incompressible Navier-Stokes equations.
