1. 6. Studies of safety and critical work situations in nuclear power plants : a human factors perspective

   Författare :Lena Kecklund; Erik Hollnagel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Safety; nuclear power; operators; work-related factors; performance; human error; annual outage; MTO; Psychology; Psykologi; psykologi; Psychology;

   Sammanfattning : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. LÄS MER

3. 7. Modelling Life Cycle Cost for Indoor Climate Systems

   Författare :Dennis Johansson; Institutionen för bygg- och miljöteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC; life cycle cost; energy; Energy research; Energiforskning; Byggnadsteknik; Building construction; indoor climate system; ventilation; maintenance; LCC;

   Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. LÄS MER

4. 8. Solar Colletors Combined with Ground-Source Heat Pumps in Dwellings - Analyses of System Performance

   Författare :Elisabeth Kjellsson; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heating in dwellings; TRNSYS simulations; solar collectors; ground-source heat pumps; ground heat;

   Sammanfattning : The use of ground-source heat pumps for heating buildings and domestic hot water in dwellings is increasing rapidly in Sweden. The heat pump extracts heat from the ground by a U-pipe in a vertical borehole. In order to reduce the electricity demand in the system, the combination with solar collectors is introduced. LÄS MER

5. 9. Finite Element Modeling of the Human Head

   Författare :Svein Kleiven; KTH; []
   Nyckelord :Finite element method FEM ; Human head; brain; head injury; epidemiology; statistics; simulations.;

   Sammanfattning : The main objectives of the present thesis were to define the dimension of head injuries in Sweden over a longer period and to present a Finite Element (FE) model of the human head which can be used for preventive strategies in the future. The annual incidence of head injuries in Sweden between 1987 and 2000 was defined at over 22 000, cases most of which were mild head injuries. LÄS MER

7. 10. Do Dividend Changes Really Signal? : Evidence from Sweden

   Författare :Per Alkebäck; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dividend policy; joint announcements; dividend initiations and omissions; dividend changes and surrounding quarterly and annual earnings; and the management s view of dividends; Business studies; Företagsekonomi; Business Administration; företagsekonomi;

   Sammanfattning : The purpose of the studies in this thesis is to clarify and hopefully shed some light on one important issue in dividend policy: the market reaction to announcements of cash dividends (changes) on the Swedish market.The first study, Joint Dividend and Earnings Announcements, Firm Size and Tax Law Changes, examines stock price reaction to joint dividend and earnings announcements.
