1. 11. Walking ability, balance and accidental falls in persons with Multiple Sclerosis

   Författare :Ylva Nilsagård; Lars-Gunnar Gunnarsson; Eva Denison; Katrin Boström; Christina H. Opava; Örebro universitet; []
   Nyckelord :multiple sclerosis; cooling garment; gait; walking; balance; reliability; validity; accidental falls; prediction; ICF; MEDICINE; MEDICIN; Medicin; Medicine;

   Sammanfattning : By using a pragmatic paradigm, different research methodologies were employed in this thesis. MS-related symptoms may be exaggerated due to heatsensitivity and it is supposed that cooling garments relieve the symptoms. LÄS MER

3. 12. Realise the Potential! : Cost Effective and Energy Efficient District Heating in European Urban Areas

   Författare :Urban Persson; Sven Werner; Louise Trygg; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width;

   Sammanfattning : The Member States of EU27 need to accelerate the integration of energy efficient technology solutions to reach the 20% energy efficiency target set for 2020. At current pace, projections indicate that only half of expected primary energy reductions will be reached. LÄS MER

4. 13. On-Engine Turbocharger Performance Considering Heat Transfer

   Författare :Habib Aghaali; Hans-Erik Ångström; Jose R. Serrrano; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

   Sammanfattning : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. LÄS MER

5. 14. Heat Transfer in Circulating Fluidized Bed Boilers

   Författare :Claes Breitholtz; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; similarity; char; heat transfer; tube wall; circulating fluidized bed; particle; radiation; scaling; particle convection; gas convection;

   Sammanfattning : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. LÄS MER
