End-pumped solid-state lasers.
This dissertation consists of four sections, with the focus on near- and mid-infrared lasers using Yttrium Lithium Fluoride (YLF) crystals doped with various rare-earth ions as a gain medium. As introduction a general ...
Computational studies of percolation : determination of the cluster number scaling function for lattices in 2 dimensions.
The main aim of this work is to study percolation theory on regular two dimensional
Mapping of magnetospheric electric fields from Cluster into ionospheric convection from SuperDARN using the Tsyganenko field model.
The data from Super Dual Auroral Radar Network (SuperDARN) radar and Cluster was used to investigate whether the processes observed by SuperDARN radar in the highlatitude ionosphere leads to the processes that take place ...
An investigation of high velocity flows in HF radar data during northward interplanetary magnetic field, non-substorm intervals.
Several previous studies, including one using early Sanae radar data, have found examples of high speed ionospheric plasma flows on the nightside, mapping to the magnetospheric tail, during periods which were magnetically ...
Numerical sampling of nonadiabatic dynamics of quantum-classical systems.
The simulation of the dynamics of quantum systems is very di cult, due to the fact that, in general, it cannot be calculated exactly for interacting many-body systems. Brute force simulations of quantum dynamics are ...
Feasibility study of ionospheric tomography using HF radar
This thesis gives an outline of the ionosphere and studies that were conducted to investigate
An investigation of ultra low frequency (ULF) pulsations using radar data and solar wind data.
An investigation of Ultra Low Frequency (ULF) pulsations was conducted using data
