1. 16. Multichannel Audio Signal Processing : Room Correction and Sound Perception

   Författare :Adrian Bahne; Anders Ahlén; Lars-Johan Brännmark; Mathias Johansson; Peter Händel; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio signal processing; multichannel sound reproduction; equalizers; human sound perception; room correction; Elektroteknik med inriktning mot signalbehandling; Electrical Engineering with specialization in Signal Processing;

   Sammanfattning : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. LÄS MER

3. 17. Evaluation of energy conserving measures in buildings connected to a district heating system : case studies in Gävle, Sweden

   Författare :Mattias Gustafsson; Björn Karlsson; Magnus Åberg; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energieffektivisering; miljonprogrammet; solceller;

   Sammanfattning : When different energy conserving measures are implemented for reducing energy use in buildings and the buildings are connected to district heating systems, it is important that an overall system analysis is made which takes into account the effects of total change of energy use due to the energy conserving measures.The method applied in this thesis uses hourly production data for the different production units in the district heating system in Gävle, Sweden.

4. 18. Exploring the Universe Using Neutrinos : A Search for Point Sources in the Southern Hemisphere Using the IceCube Neutrino Observatory

   Författare :Rickard Ström; Allan Hallgren; Olga Botner; Chad Finley; Lawrence R. Sulak; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino sources; neutrino telescopes; IceCube; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : Neutrinos are the ideal cosmic messengers, and can be used to explore the most powerful accelerators in the Universe, in particular the mechanisms for producing and accelerating cosmic rays to incredible energies. By studying clustering of neutrino candidate events in the IceCube detector we can discover sites of hadronic acceleration. LÄS MER

5. 19. Electrochemical water splitting based on metal oxide composite nanostructures

   Författare :Aneela Tahira; Omer Nur; Magnus Willander; Rasit Turan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Composite metal oxides; hydrothermal method; water splitting; Tafel slope; stability; durability; alkaline media; acidic media;

   Sammanfattning : The occurrence of available energy reservoirs is decreasing steeply, therefore we are looking for an alternative and sustainable renewable energy resources. Among them, hydrogen is considered as green fuel with a high density of energy. LÄS MER

7. 20. Physiotherapeutic perspectives on balance control after stroke : exercises, experiences and measures

   Författare :Mialinn Arvidsson Lindvall; Anette Forsberg; Agneta Anderzén Carlsson; Peter Appelros; Charlotte Ytterberg; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; balance; physiotherapy; measures; experiences;

   Sammanfattning : The overall aim of this thesis was to investigate physiotherapeutic perspectives on balance after stroke, in terms of exercises, experiences and measurements. Study I was a pilot randomized controlled trial with 46 persons who had had a stroke, 24 of whom were included in the intervention group and 22 who were included in the control group. LÄS MER
