  1. 16. Single Phase Active Power Factor Correction Converters - Methods for Optimizing EMI, Performance and Costs

    Författare :Supratim Basu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna Factor; Diode Recovery Time; Harmonic currents; EMI; Quasi Park; Snap Factor; PFC;

    Sammanfattning : In this thesis, front-end solutions with single-phase power factor correction (PFC) capability are studied. The reduction of current harmonics using various PFC techniques is investigated and related to the EN 61000-3-2 standard. LÄS MER

  3. 17. Service life estimation in building design : A development of the factor method

    Författare :Björn Marteinsson; Christer Sjöström; Michael A. Lacasse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; factor method; service life prediction; durability; degradation; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : The built environment usually constitutes a very important part of the real capital of a nation, and the construction sector represents more than 10% of the yearly Gross National Product of the industrialised world. Good planning of all construction is important, and consideration of the service life of the work is of great interest and is a significant aspect of sustainability considerations. LÄS MER

  5. 19. Factor Demand and Market Power

    Författare :Magnus Sjöström; Runar Brännlund; Patrik Söderholm; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; demand and supply; dynamic factor demand; adjustment costs; bootstrap; panel data; market power; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : The objective of Paper [I] is to analyze potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as fuel in energy generation. An increasing use of forest resources as an energy input may have effects outside the energy sector. LÄS MER

  7. 20. lac of Time : Transcription Factor Kinetics in Living Cells

    Författare :Petter Hammar; Johan Elf; Antoine van Oijen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription factor; lac operon; facilitated diffusion; single molecule imaging; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. LÄS MER
