1. 6. Design and Stability of Cu(In,Ga)Se2-Based Solar Cell Modules

   Författare :Johan Wennerberg; Michael Powalla; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Thin film solar cells; CIGS; Cu In; Ga Se2; stability; lifetime; testing; Elektronik; Electronics; Elektronik; Elektronik; Electronics;

   Sammanfattning : Cu(In,Ga)Se2 (CIGS) is one of the most promising semiconductor compounds for large-scale production of efficient, low-cost thin film solar cells, and several research institutes have announced their plans for CIGS production lines. But for the CIGS technology to become a commercial success, a number of issues concerning manufacturability, product definition, and long-term stability require further attention. LÄS MER

3. 7. Removal of ultrafine particles by intermediate air filters in ventilation systems. Evaluation of performance and analysis of applications

   Författare :Bingbing Shi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurements; ultrafine particles; lifetime cost; indoor air quality; health effect; air cleaning; particle source; modelling; intermediate filter; filter standard;

   Sammanfattning : Epidemiological and toxicological studies demonstrate that ultrafine particles (UFPs) are strongly related with respiratory and cardiovascular diseases and syndromes. One common method to reduce human exposure to particulate air pollution is the use of intermediate class filters (F5-F9 class filters according to EN779:2002). LÄS MER

4. 8. Aspects of historical data and health criteria for drinking water network replacement strategies

   Författare :Annika Malm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pipe rehabilitation; water distribution network; cost-benefit analysis; Pipe replacement; leakage control; lifetime distribution; pipe failure; health risk; strategic planning; asset management;

   Sammanfattning : The drinking water distribution network represents a major proportion of the investments and capital assets of a water utility. Consequently, qualified insight into future replacement needs provides water utilities with a foundation for financial planning. LÄS MER

5. 9. Data-driven lead-acid battery lifetime prognostics

   Författare :Sergii Voronov; Erik Frisk; Mattias Krysander; Jonas Biteus; Thorsteinn Rögnvaldsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : To efficiently transport goods by heavy-duty trucks, it is important that vehicles have a high degree of availability and in particular avoid becoming standing by the road unable to continue the transport mission. An unplanned stop by the road does not only cost due to the delay in delivery, but can also lead to a damaged cargo. LÄS MER

7. 10. Lithium ion Battery Aging: Battery Lifetime Testing and Physics-based Modeling for Electric Vehicle Applications

   Författare :Evelina Wikner; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics-based modeling; Electric Vehicle EV ; Battery lifetime tests; Hybrid Electric Vehicle HEV ; Plug-in Hybrid Electric Vehicle PHEV ; Calendar aging;

   Sammanfattning : Electrification of vehicles is one solution in reducing emissions from the transport sector, and in particular to limit tail-pipe emissions in cities. In order to make the electrification successful and cost effective, there is a high demand for longer drive range and longer battery lifetime. LÄS MER
