  2. 6. Study of Induction Machines with Rotating Power Electronic Converter

    Author : Yanmei Yao; Chandur Sadarangani; Zi-Qiang Zhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brushless induction machine; efficiency improvement; optimum efficiency; rotating power electronic converter; unity power factor; variable power factor; wound rotor induction machine; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis investigates a novel induction machine topology that uses a rotating power electronic converter. Steady-state and dynamic performance of the topology is studied to understand its operational principle. Furthermore the potential of improving its efficiency and power factor is investigated.

  4. 7. Designing Information Systems : A pragmatic account

    Author : Jonas Sjöström; Pär Johan Ågerfalk; Göran Goldkuhl; Else Nygren; Richard Baskerville; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; information systems; design; pragmatism; design research; it artefact; Informatics and systems science; Informatik och systemvetenskap; Computer and systems science; Data- och systemvetenskap; Informatics; Informatik; Data- och systemvetenskap; Computer Systems Sciences;

    Abstract : Information technology (IT) plays an increasingly important role for individuals, organizations, markets, and society as a whole. IT systems are artefacts (human made objects) designed for various purposes. READ MORE

  5. 8. Internal Design of a Class of Self-Excited Synchronous Generators

    Author : Mohamed Wadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft Magnetic Composites; Hydropower Plants; Brushless Excitation; Self-Excited Generators; Renewable Energy; Reluctance Generators; Synchronous Generators; Small Hydropower;

    Abstract : INTERNAL DESIGN OF A CLASS OF SELF-EXCITEDABSTRACTWith the increasing trend of distributed generation and the need for alternative and renewable energy sources, self-excited induction and synchronous reluctance generators have attracted more attention for wind, tidal and hydropower applications. This thesis is concerned with the development of a class of self-excited synchronous reluctance generators (SRG). READ MORE

  6. 9. Conformation of polypeptides at nanoparticles interfaces : protein structural changes and induced folding of peptides

    Author : Martin Lundqvist; Fredrik Höök; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis can be divided into two parts. The first deals with characterization of structural and dynamic consequences for proteins of interactions with a solid surface in the form of silica nanoparticles. READ MORE

  7. 10. Design, production and characterization of synthetic immunogens : application on Plasmodium falciparum malaria antigens

    Author : Anders Sjölander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The development of synthetic subunit vaccines is presently one of the major strategies to construct vaccines against infectious diseases. Such vaccines are based on isolated and characterized immunogens and should include appropriate B- and T-cell epitopes. READ MORE
