1. 11. Properties and evaluation of volatility models

   Författare :Hans Malmsten; Handelshögskolan i Stockholm; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The general theme of this thesis is theoretical properties and evaluation of volatility models. The thesis consists of four papers. In the first chapter the moment structure of the EGARCH model is derived. The second chapter contains new results on the A-PARCH model. LÄS MER

3. 12. Scenario trees for inflow modelling in stochastic optimisation for energy planning

   Författare :Roger Halldin; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The Nordic countries Norway, Sweden, Finland and Denmark have formed a deregulated power market. Electricity bought and sold on this market is dominated by hydro power. However, hydro power generation is restricted by the amount of water in reservoirs. LÄS MER

4. 13. Characterisation and Applications of Ultrashort Extreme Ultraviolet Pulses

   Författare :Johan Norin; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ultrashort pulses; pulse characterisation; sidebands; interferometry; Atom- och molekylärfysik; acetylene; Atomic and molecular physics; High-order harmonics; XUV; Fysicumarkivet A:2002:Norin;

   Sammanfattning : When a strong laser field interacts with free atoms, harmonics up to very high orders are created. This extreme ultraviolet (XUV) radiation has interesting properties, such as spatial and temporal coherence, short pulse duration and high brightness. This thesis concentrates on the temporal aspects of this radiation. LÄS MER

5. 14. Spatial Spillovers of Knowledge Production : An Accessibility Approach

   Författare :Urban Gråsjö; Högskolan Väst; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nationalekonomi; Business and economics; Ekonomi; Economics; Nationalekonomi; Economics;

   Sammanfattning : The main focus of the thesis is on issues concerning production of knowledge. It is a common observation that knowledge activities have a tendency to agglomerate as well as to spill over in space. LÄS MER

7. 15. Fluorescence correlation spectroscopy, photophysical aspects and applications

   Författare :Jerker Widengren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Fluorescence correlation spectroscopy (FCS) is a technique where dynamic processes on the molecular level are studied by the use of fluorescence. The molecules are excited within a focused stationary laser beam and the resulting fluorescence fluctuations are analyzed in the form of an autocorrelation function. LÄS MER
