A widely used method for determination of transition probabilities and oscillator strengths is based on measurements of branching fractions and radiative lifetimes. In the present work the different sources of uncertainty in branching fraction measurements using Fourier transform spectroscopy and lifetime measurements using laser induced fluorescence are discussed. A detailed description is presen
Popular Abstract in Swedish En central fråga av både teoretisk och praktisk betydelse är varför vissa företag är mer framgångsrika - vilket ofta uttrycks som att de har större konkurrensfördelar - än andra. Speciellt uppkommer frågan då vissa fabriker inom samma företag år efter år uppvisar ett bättre ekonomiskt resultat än andra. Fokus i denna avhandling är att förstå varför så sker inom ett utvaThe most central question in the strategic management literature is why some firms are more successful than others, often expressed as an aim to understand sources of competitive advantage. In this thesis, an empirical observation is made that a number of manufacturing plants belonging to the same firm show sustainable differences in financial success, and the question is why. The main theoretical
Abstract in Undetermined The 60 GHz band is very prominsing for high data rate (>1 Gb/s) wireless systems operating at short ranges. However, due to the short wavelengths in this frequency band, the shadowing effects cuased by human bodies and furniture are severe and needs to be modeled properly. In this paper, we present an experimental, measurement-based characterization of the reflection and s
Boken innehåller praktiska övningar på moment inom olika delar av grammatiken: morfologi och ordklasser, ordbildning, syntax och språklig variation. Till övningarna finns facit med kommentarer. Kategoriseringarna och användningen av termer bygger på läroboken Svensk universitetsgrammatik för nybörjare, som i stort behandlar samma stoff. Övningsboken fungerar dock oberoende av läroboken, eftersom v
An organization aiming to survive on a more challenging or changing market has to adapt or fundamentally change the way it is doing business. For the Swedish forest products industry, and more specifically the paper packaging industry, the market challenges range from saturated home markets, competing materials and increasing production costs, to growth of new markets and more powerful actors in t
Synthesis of case studies is different from synthesis of purely quantitative studies, for example, in that sampling and analysis in primary studies have been carried out differently, and that primary results are of a different nature. The objective of this research is to identify what challenges should be considered when choosing and using a method for synthesis of case studies. We collected exper
This symposium presents two tracks, one practical and one more theoretical, divided in ten topics, and presented in three parallel sessions. Two new topics are introduced; “Historical Buildings” and “Challenges for the future”. The intention of adding Historical Buildings is to gather people with different backgrounds, for example Building Physicists, Building antiquarians, Building Biologists, Ar
This doctoral dissertation has aimed to contribute to a modern theory of the firm that balances a disciplining view of the firm with an enabling view of the firm. This has been approached through exploring how corporate governance mechanisms influence entrepreneurship at the organisational level, in a frame of property rights. As such, the research model that guides the dissertation depicts a mode
This thesis presents a study of DX center related phenomena in silicon doped AlGaAs and in GaAs/AlGaAs multi-layer structures. A variety of experimental techniques such as capacitance-voltage (C-V), deep level transient spectroscopy (DLTS), single shot capacitance, thermally stimulated capacitance (TSCAP), admittance spectroscopy, photocapacitance, and photoconductivity have been used. The main re
