1. 1. Building Retrofit using Vacuum Insulation Panels: Hygrothermal Performance and Durability

   Författare :Pär Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory; retrofitting; interior insulation; listed building; field study; exterior wall; brick wall; numerical simulation; wooden beam ends; measurement; vacuum insulation panel; transient plane heat source; exterior insulation;

   Sammanfattning : Many old buildings have unsatisfactory thermal performance compared to the standards of today. One way to increase the thermal performance is to add thermal insulation to the building envelope. However, many old buildings are listed and considered to be valuable for historical and esthetic reasons. LÄS MER

3. 2. Den lilla tekniken i det stora skeendet : Nanoteknik, gränser och omvärldsuppfattningar

   Författare :Anja-Sofi Karhi; Carl-Reinhold Bråkenhielm; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ICT; nanotechnology; phenomenography; dichotomy; shared figures of thoughts; border exceed; ways in which people experience; Natural – Unnatural; Living – Not-living; Exterior – Interior; IKT; nanoteknik; omvärldsuppfattningar; fenomenografi; tankefigurer; dikotomier; gränsöverskridanden; naturligt och ickenaturligt; levande och ickelevande materia; yta och innehåll; Technology and social change; Teknik och social förändring;

   Sammanfattning : Sedan några år tillbaka intar nanoteknik en position som ett av de mest "heta" och högst prioriterade forsknings- och utvecklingsområdena. Tilltron är stark till att nanotekniken kommer att påverka nästan alla aspekter av våra liv. LÄS MER

4. 3. Condensation and frost formation in fibrous thermal-insulation materials

   Författare :Tomáš Vrána; Folke Björk; Ove Söderström; Kjartan Gudmundsson; Carsten Rode; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Construction materials; Konstruktionsmaterial;

   Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER

5. 4. Retrofitting of old Exterior Wall with Vacuum Insulation Panels: Measurements of Thermal Properties, Moisture Performance and Practical Considerations

   Författare :Pär Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hygrothermal sensor; listed building; transient plane source; retrofitting; indoor moisture supply; vacuum insulation panel; hygrothermal simulation; exterior wall;

   Sammanfattning : The building industry is facing one of its most challenging tasks ever. Until 2050 the energy use for heating of buildings should be decreased by 50% which means a large part of the building stock have to be retrofitted to become more energy efficient. One of the possible solutions is to add thermal insulation to the exterior wall of the buildings. LÄS MER

7. 5. Modelling the vibrations on a rolling tyre and their relation to exterior and interior noise

   Författare :Patrik Sabiniarz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : For most modern cars at normal driving speeds, tyre/road interaction is a major source tothe exterior as well as interior vehicle noise. The interaction between a tyre and a roadsurface generates tyre structure vibrations, leading to sound radiation into the surroundingair, and to dynamic forces acting on the wheel hub. LÄS MER
