2. 1. Long shifts, short rests and vulnerability to shift work

   Author : John Axelsson; Torbjörn Åkerstedt; Ulf Lundberg; Phil Tucker; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sleep; alertness; sleepiness; shiftwork; compressed working hours; long shifts; 12h shifts; quick returns; quick change-overs; tolerance; gender; Psychology; Psykologi;

   Abstract : At the same time as many urban economies are developing into 24-hour societies it is becoming increasingly popular amongst shift workers to compress their working hours. This is done by working longer shifts (>8h) and/or restricting free time (... READ MORE

4. 2. Materials Supply and Product Descriptions for Assembly Systems - Design and Operation

   Author : Lars Medbo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; long cycle time work; product structure; manual assembly; parallel product flow; assembly systems design; materials kit;

   Abstract : This thesis discusses and reports on assembly systems design, concerning manual assembly of complex products involving production with requirement for flexibility in production volumes and product variants. The research is based on more than a decade of work within the Swedish automotive industry focusing on parallel product flows and long cycle time assembly work. READ MORE

5. 3. Maintenance Consideration for Long Life Cycle Embedded System

   Author : Xiaozhou Meng; Benny Thörnberg; Mattias O'Nils; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract :      In this thesis, the work presented is in relation to consideration to the maintenance of a long life cycle embedded system. Various issues can present problems for maintaining a long life cycle embedded system, such as component obsolescence and IP (intellectual property) portability. READ MORE

6. 4. Markov Regime Switching in Economic Time Series

   Author : Ulf Erlandsson; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; forecasting; Markov switching; exchange rates; interest rates; business cycle; economic policy; economic systems; economic theory; econometrics; Economics; currency crisis;

   Abstract : This dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. READ MORE

7. 5. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation

   Author : Rui-Tao Wen; Claes-Göran Granqvist; Agustín R. González-Elipe; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromic; smart windows; long-term durability; degradation kinetics; ion trapping; de-trapping; materials rejuvenation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Abstract : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. READ MORE
