1. 1. Daylighting Systems : Development of Techniques for Optical Characterization and Performance Evaluation

   Författare :Annica M. Nilsson; Arne Roos; Claes-Göran Granqvist; Marie-Claude Dubois; Michael Köhl; Uppsala universitet; []
   Nyckelord :Optical spectroscopy; integrating sphere; ray tracing; light scattering; window physics; Venetian blinds; core daylighting; optical characterization; Teknisk fysik; Engineering Science;

   Sammanfattning : Successful integration of daylighting systems requires the ability to predict their performance for given climates. In this dissertation, a bottom-up approach is applied to evaluate the optical performance of a selection of daylighting systems. LÄS MER

4. 3. Balancing variable renewable electricity generation using combined heat and power plants, large-scale heat pumps, and thermal energy storages in Swedish district heating systems

   Författare :Svante Monie; Magnus Åberg; Annica Nilsson; Joakim Widén; Magnus Wallén; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating systems; Power-to-Heat; Heat pumps; Combined heat and power; Thermal energy storage; Power balance; Variable renewable electricity; Biomass fuel; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : The global ambitions to hamper the greenhouse effect has led to ambitious targets for increasing renewable energy use. This, in combination with recent years' vast development of wind and solar power, implies that there will be significant amounts of variable renewable electricity (VRE) in future energy systems.

5. 4. Föreningsidrott som socialisationsmiljö : En studie av idrottens betydelse för barns och ungdomars psykosociala utveckling

   Författare :Stefan Wagnsson; Göran Patriksson; Solveig Hägglund; Annica Löfdahl; Per Nilsson; Karlstads universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sport; socialization; youths; self-concept; prosocial; antisocial; psychosomatic health; alcohol; tobacco; Education; Pedagogik;

   Sammanfattning : The overall purpose of this study was to examine organized youth sports in Sweden and the possible influences over time (2 years) on some of the intended socialisation effects in terms of children’s and adolescent’s self-esteem, perceived physical and social competence, self reported pro- and antisocial behaviours, self reported psychosomatic health, and use of alcohol and tobacco. In an attempt to capture some of the complex social interactions in sports, which undoubtedly leads to different socialisation experiences, an additional purpose of this study was to examine possible relations between children and adolescent athletes’ dispositional goal orientations (task and ego), perceived motivational climate in sports, perceived sport-specific competence, perceived prosocial coaching and presumptive psychosocial effect variables.
