1. 16. Byråkratins ansikten : Rolluppfattningar hos svenska högre statstjänstemän

   Författare :Anders Mellbourn; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; Statsvetenskap;

   Sammanfattning : The present study is based on interviews in 1971 with 314 top-level civil servants in the central government administration in Sweden. It is the result of a joint project at the universities of Stockholm and Michigan. Similar studies were carried out simultaneously in 5 other Western European nations and in the United States.

3. 17. High Aspect Ratio Microstructures in Flexible Printed Circuit Boards : Process and Applications

   Författare :Hanna Yousef; Klas Hjort; Mikael Lindeberg; Peter Leisner; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; flexible printed circuit boards; polyimide; through-hole vias; ion track technology; thermoelectricity; thermopiles; substrate integrated waveguides; millimeter wave devices; Teknisk fysik; Engineering physics; Teknisk fysik;

   Sammanfattning : Flexible printed circuit boards (flex PCBs) are used in a wide range of electronic devices today due to their light weight, bendability, extensive wiring possibilities, and low-cost manufacturing techniques. The general trend in the flex PCB industry is further miniaturization alongside increasing functionality per device and reduced costs. LÄS MER

4. 18. Flexural Buckling of High-Strength Steel Columns

   Författare :Gabriel Sabau; Ove Lagerqvist; Torsten Höglund; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

   Sammanfattning : The European standards dealing with design rules and recommendations for steel structures have been under revision in the past years due to the increased use of high-strength steels. High-strength steels popularity increased at a steady pace in the last decades since they allow for more light-weighted solutions than conventional steels. LÄS MER

5. 19. Towards application of explicit likelihoods in inference for Dark Matter Direct Detection

   Författare :Pueh-Leng Tan; Jan Conrad; Klas Hultqvist; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

   Sammanfattning : Despite the many empirical hints for the existence of Dark Matter in the Universe, Dark Matter has yet to be observed experimentally, be it directly through its scatterings in detectors, indirectly through its annihilation in the galaxy, or implicitly through its production and decay in particle colliders. Even though observations from astrophysics and cosmology placed constraints on the Dark Matter energy density and self-interaction cross section and with Standard Model particles, much about the nature of Dark Matter is still unknown, leaving much to the creativity of model builders.

7. 20. Processes in Optical Diesel Engines - Emissions Formation and Heat Release

   Författare :Ulf Aronsson; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Engines; Optical Engines; Heat Release; Combustion; Emissions Formation; Mechanical Deformation;

   Sammanfattning : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. LÄS MER
