11. Monte Carlo Simulations of Homogeneous and Inhomogeneous Transport in Silicon Carbide
Sammanfattning : The importance of simulation is increasing in the researchon semiconductor devices and materials. Simulations are used toexplore the characteristics of novel devices as well asproperties of the semiconductor materials that are underinvestigation, i.e. generally materials where the knowledge isinsufficient.

12. Coarse Graining Monte Carlo Methods for Wireless Channels and Stochastic Differential Equations
Sammanfattning : This thesis consists of two papers considering different aspects of stochastic process modelling and the minimisation of computational cost. In the first paper, we analyse statistical signal properties and develop a Gaussian pro- cess model for scenarios with a moving receiver in a scattering environment, as in Clarke’s model, with the generalisation that noise is introduced through scatterers randomly flip- ping on and off as a function of time.

13. Studies of clinical proton dosimetry using Monte Carlo simulation and experimental techniques
Sammanfattning : The present work aims at improving clinical proton dosimetry based on ionization chambers, and to bring its state of development closer to the corresponding status of conventional photon and electron dosimetry. In order to accomplish this, both theoretical and experimental methods have been used. LÄS MER
14. Monte Carlo Simulations of the Equilibrium Properties of Semi-stiff Polymer Chains : Efficient Sampling from Compact to Extended Structures
Sammanfattning : Polymers is a class of molecules which can have many different structures due to a large number of degrees of freedom. Many biopolymers, e.g. DNA, but also synthetic macromolecules have special structural features due to their backbone stiffness. LÄS MER
15. Development of Experimental Brachytherapy Dosimetry Using Monte Carlo Simulations for Detector Characterization
Sammanfattning : Brachytherapy (BT) is a type of interventional radiotherapy that is advantageous due to high absorbed dose conformity and possibility to deliver high dose in few fractions. It is often used for prostate and gynecological tumors as monotherapy or a boost alongside external beam radiotherapy (EBRT). LÄS MER
