2. 1. Reflector Optimization for Low Concentration Photovoltaic-Thermal Solar Collectors

   Author : Diogo Cabral; Hans Wigö; Björn O. Karlsson; Maria João Carvalho; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic-thermal collector; experimental assessment; collector performance assessment; optical efficiency; concentrating PVT solar collector; ray tracing; Fotovoltaisk-termisk kollektor; experimentell utvärdering; prestandautvärdering; optisk effektivitet; koncentrerande PVT-solfångare; strålgångsanalys;

   Abstract : 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.

   Abstract : Fossil fuels have greatly improved human living standards and saved countless lives. However, today, their continued use threatens human survival, as CO2 levels rise at an unprecedented pace to levels never seen during human existenceon earth. READ MORE

5. 3. Room Acoustic Ray-Tracing : Understanding, evaluating and expanding the toolset

   Author : Hanna Autio; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Room acoustics; acoustic ray tracing; Room acoustic simulation; virtual reality; acoustic scattering;

   Abstract : 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.

6. 4. Pay tracing tools for high frequency electromagnetics simulations

   Author : Sandy Sefi; KTH; []
   Keywords : CEM; GTD; Ray Tracing; NURBS; Software Architecture; Shadowing;

   Abstract : Over the past 20 years, the development in ComputationalElectromagnetics has produced a vast choice of methods based onthe large number of existing mathematical formulations of theMaxwell equations. None of them dominate over the others,instead they complement each other and the choice of methoddepends on the frequency range of the electromagnetic waves. READ MORE

7. 5. Tracing Molecular Conformations by X-ray Solution Scattering

   Author : Alexandr Nasedkin; Jan Davidsson; Pau Bernado; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In the present work the refinement of X-ray data have been used to solve different scientific problems, namely drug localization in the liposome wall, reaction kinetics of the small molecule upon excitation and resolving an ensemble of protein structures at different temperatures. The common approach included collection of X-ray scattering patterns, modelling of the system of interest in atomic level and fitting computed results to experimental data. READ MORE
