  1. 1. On soft-switching isolated AC/DC converters without auxiliary circuit

    Author : Staffan Norrga; Stefan Östlund; Rik De Doncker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; voltage source converter; cycloconverter; isolated converter; medium frequency transformer; soft switching; modulation; commutation; wind power; electric traction; Elkraftteknik; Electric power engineering; Elkraftteknik;

    Abstract : The thesis is concerned with a class of power electronic converter systems that permit bidirectional AC/DC conversion with galvanic separation of the AC and DC sides by a transformer operating at elevated frequency. The systems consist of a capacitively snubbered voltage source converter and a cycloconverter, separated by the mentioned transformer. READ MORE

  2. 2. Studies on Molecular Genetics of B cell Development

    Author : Panagiotis Tsapogas; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunoglobulin; gene expression; B cell; EBF; class switching; TGF-beta; Immunology; transplantation; serologi; Immunologi; serology;

    Abstract : The development of immature progenitor cells into highly differentiated effector cells is a process central in modern medicine with applications in the fields of cell therapy as well as oncology. This thesis is focused on the molecular mechanisms that control the development of B lymphocytes. READ MORE

  3. 3. Immunoglobulin isotype switching in health and disease

    Author : Berivan Baskin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Immunoglobulin isotype switching is the process where the Cmy region, initially located downstream of the VDJ region is replaced by another constant region gene. Class switch recombination takes place between switch (S) regions, composed of tandem repeats of short unit sequences, located 5 of each CH gene, except for Cdelta. READ MORE

  4. 4. Model Checking Methods for Mode Switching Systems

    Author : Valur Einarsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with modeling and analysis of a special class of hybrid systems, i.e., systems displaying behavior of both continuous and discrete nature. READ MORE

  5. 5. Switching Kinetics and Charge Transport in Organic Ferroelectrics

    Author : Tim Cornelissen; Martijn Kemerink; Mats Fahlman; Kamal Asadi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Electronics; Ferroelectrics; Organic Ferroelectrics;

    Abstract : The continued digitalization of our society means that more and more things are getting connected electronically. Since currently used inorganic electronics are not well suited for these new applications because of costs and environmental issues, organic electronics can play an important role here. READ MORE
