1. 11. Power to the people : electricity demand and household behavior

   Författare :Mattias Vesterberg; Runar Brännlund; Chandra Kiran Krishnamurthy; Maximilian Auffhammer; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity demand; real-time pricing; demand flexibility; elasticity; appliance-level data; end-use; media; contract choice; de-regulated market; household behavior; intermittent electricity production; efficiency; imperfect information;

   Sammanfattning : Paper [I] Using a unique and highly detailed data set on energy consumption at the appliance-level for 200 Swedish households, seemingly unrelated regression (SUR)-based end-use specific load curves are estimated. The estimated load curves are then used to explore possible restrictions on load shifting (e.g. LÄS MER

3. 12. Aspects on Dynamic Power Flow Controllers and Related Devices for Increased Flexibility in Electric Power Systems

   Författare :Nicklas Johansson; Hans-Peter Nee; Göran Andersson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Control; Controlled Series Compensator; Dynamic Power Flow Controller; Frequency Scanning; Phase-Shifting Transformer; Power Controller Plane; Power Flow Control; Power Oscillation Damping; Subsynchronous Resonance; Thyristor Controlled Series Compensator; Thyristor Switched Series Compensator; Transient Stability; Electrical engineering; Elektroteknik;

   Sammanfattning : This thesis studies different aspects of Flexible AC Transmission System (FACTS) devices which are used to improve the power transfer capability and increase the controllability in electric power systems. In the thesis, different aspects on the usage and control of Dynamic Power Flow Controllers (DPFC) and related FACTS devices are studied. LÄS MER

4. 13. Windows of Opportunities : The Glazed Area and its Impact on the Energy Balance of Buildings

   Författare :Mari-Louise Persson; Arne Roos; Maria Wall; Ida Bryn; Uppsala universitet; []
   Nyckelord :Engineering physics; building simulations; DEROB-LTH; glazing; window size; energy efficiency; glazed area; Teknisk fysik;

   Sammanfattning : The impact of window area on the energy balance of a building was investigated by simulations in DEROB-LTH. The glazed area was varied in three types of buildings with different types of glazing and for several climates.One low energy house was compared to a less insulated house but identical in size and layout.

5. 14. Developing high performance manufacturing systems

   Författare :Anders Karlsson; KTH; []
   Nyckelord :manufacturing control; manufacturing sytem design; assembly-intiated production; flexible manufacturing;

   Sammanfattning : The work detailed in this dissertation relates to thedevelopment of high performance manufacturing systems. Theperformance factor aimed for is especially flexibility, butthere is an intention of making the results adaptable to focuson performance factors of the readers or users choice. LÄS MER

7. 15. Integration and Fabrication Techniques for 3D Micro- and Nanodevices

   Författare :Andreas C. Fischer; Frank Niklaus; Karl F. Böhringer; KTH; []
   Nyckelord :Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; chip-level; through silicon via; TSV; packaging; 3D packaging; vacuum packaging; liquid encapsulation; integration; heterogeneous integration; wafer bonding; microactuators; shape memory alloy; SMA; wire bonding; magnetic assembly; self-assembly; 3D; 3D printing; focused ion beam; FIB;

   Sammanfattning : The development of micro and nano-electromechanical systems (MEMS and NEMS) with entirely new or improved functionalities is typically based on novel or improved designs, materials and fabrication methods. However, today’s micro- and nano-fabrication is restrained by manufacturing paradigms that have been established by the integrated circuit (IC) industry over the past few decades. LÄS MER
