   Abstract : This doctoral thesis provides a comprehensive numerical analysis and exploration of several stochastic partial differential equations (SPDEs). More specifically, this thesis investigates time integrators for SPDEs with white noise dispersion. READ MORE

4. 2. MaMiS : A Programming Environment for Numeric/Symbolic Data Processing

   Author : Peter A. J. Nagy; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheme; MATLAB; MACSYMA; Numeric symbolic data processing;

   Abstract : This thesis describes a programming environment (called MaMiS - MATLAB and MACSYMA in Scheme) for symbolic/numeric data processing. This programming environment is based on three main parts:Scheme, a symbol manipulating language (a LISP dialect)MATLAB, a program for numeric scientific calculationsMACSYMA, a program for formula manipulationsA fourth part is added to MaMiS, the text editor DNU Emacs, which is used as an interface between the user and Scheme.

5. 3. Software tools for matrix canonical computations and web-based software library environments

   Author : Pedher Johansson; Bo Kågström; Erik. Elmroth; Alan Edelman; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Canonical structure; Jordan canonical form; controllability; StratiGraph; Matlab toolbox; Kronecker canonical form; matrix; matrix pencil; perturbation theory; closure hirerarchy; matrix stratification; control system; observability; Numerical analysis; Numerisk analys;

   Abstract : This dissertation addresses the development and use of novel software tools and environments for the computation and visualization of canonical information as well as stratification hierarchies for matrices and matrix pencils. The simplest standard shape to which a matrix pencil with a given set of eigenvalues can be reduced is called the Kronecker canonical form (KCF). READ MORE

6. 4. Numerical simulation of shape rolling

   Author : Stanislav Riljak; Stefan Jonsson; Peter Gudmundson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire-rod rolling; finite-element method; generalized plane-strain; dislocation density; material model; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : In the first part of this thesis, the FE program MSC.Marc is applied for coupled thermomechanical simulations of wire-rod rolling. In order to predict material behaviour of an AISI 302 stainless steel at high strain rates generated during wire-rod rolling, a material model based on dislocation density is applied. READ MORE

7. 5. Tumour vasculature, oxygenation and radiosensitivity - a numerical modelling study

   Author : Jakob Heydorn Lagerlöf; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Dosimetry; Hypoxia; Modelling; Radionuclide therapy; Radiotherapy; Tumour Control Probability;

   Abstract : This thesis aims to investigate theoretically how parameters such as vessel density, blood oxygenation, blood velocity, spatial oxygen variation along vessels, tissue oxygen consumption and their distributions in uence the radiosensitivity of tumours. Numerical calculations are made in Matlab using voxel-based models. READ MORE
