2. 11. A Fast Pixelated Thermal-Neutron Detector

   Author : Emil Rofors; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SoNDe; thermal-neutron detector; GS20 scintillator; Li-glass; H12700A MAPMT; position-dependent response; alpha-particle; proton; deuteron; neutron; ESS; SKADI;

   Abstract : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.

4. 12. Thermal Modelling of Power Modules in a Hybrid Vehicle Application

   Author : Jonas Ottosson; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Module; Thermal Modelling; Electro-Thermal Simulations; Reliability; Cooling requirements;

   Abstract : Hybrid electric and full electric vehicles have attracted growing attention during the last decade. This is a consequence of several factors, such as growing environmental concerns, increasing oil prices and a strive for oil independency. READ MORE

5. 13. In-situ testing of floating thermal piles in soft sensitive clay

   Author : Anders Bergström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintained; Cyclic Thermal loading; Energy piles; Field Test; Thermal Piles;

   Abstract : Thermal piles are structural piles with additional function of working as geothermal heat exchangers towards the soil volume. Heating and cooling process of soft soils is known to affect the stress state and soil structure, with potential consolidation settlements and creep as undesired consequences. READ MORE

6. 14. Mechanisms of Electrical Ageing of Oilimpregnated Paper due to Partial Discharges

   Author : Mohamad Ghaffarian Niasar; Hans Edin; Ernst Gockenback; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial discharges; oil-impregnated paper; oil; transformer insulation; dielectric frequency response; breakdown strength; ion mobility; thermal ageing; electrical ageing; moisture in paper; life time; thermal breakdown.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis, partial discharge (PD) phenomenon in oil-impregnated paper (OIP) is investigated under accelerated electrical stress. The thesis is mainly focused on the characteristic of PD activity and the influence it has on the insulation properties of OIP. READ MORE

7. 15. A Systematic Approach to Integrated Building Performance Assessment and Visualisation

   Author : Samer Hassanie; Ivo Martinac; Holger Wallbaum; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal comfort; energy consumption; building certifications; occupancy; modeling; presence; pattern recognition; Demand controlled ventilation; Indoor thermal environment; Occupancy; Time response; Energy use; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : The aim of this project was to develop a holistic approach to building-performance assessment without limiting it to energy use (usually expressed in kWh/m2/year), but rather include more parameters that represent the following aspects: Economic, environmental, and quality of service provided to the occupant/client. If it can be shown that buildings can be operated not only in an energy-efficient way, but also in a way that takes into consideration the needs of the occupants, a case could be built that a higher quality of indoor environment does not necessarily mean a higher economic impact.
