1. Room Acoustic Ray-Tracing : Understanding, evaluating and expanding the toolset
Sammanfattning : Room acoustic simulations are an important tool, both for design of spaces with satisfactory acoustics and for use in virtual reality experiences. Auralization of acoustic simulations are becoming more and more important in the context of Virtual and Augmented reality (VR and AR respectively), as the technology is used more and more in healthcare, culture and research.

2. On the Search for High-Energy Neutrinos : Analysis of data from AMANDA-II
Sammanfattning : A search for a diffuse flux of cosmic neutrinos with energies in excess of 1014 eV was performed using two years of AMANDA-II data, collected in 2003 and 2004. A 20% evenly distributed sub-sample of experimental data was used to verify the detector description and the analysis cuts. LÄS MER
3. Reflector Optimization for Low Concentration Photovoltaic-Thermal Solar Collectors
Sammanfattning : The alarming new global warming and increasing awareness related to climate change (mainly due to the high emissions of carbon dioxide) in recent decades linked all nations into a common cause, which requires ambitious efforts to combat climate change by adapting energy systems to its effects.The knowledge gain presented in this dissertation establishes the foundations for the development of a more efficient concentrating photovoltaic-thermal (PVT) solar collector.

4. Optical Analysis and Characterisation of the Climate Research Instrument STEAMR
Sammanfattning : A growing interest for making high resolution observations in the upper troposphere and lower stratosphere has motivated the development of the multi-beam satellite-borne instrument Stratosphere-Troposphere Exchange And climate Monitor Radiometer (STEAMR). The measurements made by STEAMR will be used to monitor trace-gases and link the occurence of these to the Earth's climate by accurate modeling of the atmosphere. LÄS MER
5. Solar cavity receiver design for a dish-Stirling system
Sammanfattning : The growing concern for the climate change has led to an increasing research effort in renewable energy technologies in order to achieve a more sustainable electricity production. Concentrating Solar Power (CSP) is identified as a promising technology to deal with part of the future electricity production. LÄS MER
