  2. 26. Analysis, Modeling and Control of Doubly-Fed Induction Generators for Wind Turbines

    Author : Andreas Petersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the analysis, modeling, and control of the doubly-fed induction machine used as a wind turbine generator. The energy efficiency of wind turbine systems equipped with doubly-fed induction generators are compared to other wind turbine generator systems. READ MORE

  4. 27. Investigation of AC electrical machine stators with fractional conductor windings

    Author : Henrik Grop; Juliette Soulard; Yujing Liu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; windings; leakage; large machines; induction motor construction; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Industry always searches the least expensive solution for a machine design. Therefore, there is a need for integrating different customer ordered machines within the same frame, while keeping the foundation of the mechanical design constant. READ MORE

  5. 28. Light-Triggered Conformational Switches for Modulation of Molecular Recognition : Applications for Peptidomimetics and Supramolecular Systems

    Author : Magnus Blom; Adolf Gogoll; Morten Grötli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bisporphyrin tweezers; peptidomimetics; host-guest systems; conformational analysis; supramolecular chemistry; photochemistry; Organisk kemi; Organic Chemistry; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The main focus of this thesis is on photochemical modulation of molecular recognition in various host-guest systems. This involves the design, synthesis and integration of light-triggered conformational switches into peptidomimetic guests and molecular tweezer hosts. READ MORE

  6. 29. Improved performance characteristics of induction machines with non-skewed symmetrical rotor slots

    Author : Rathna Chitroju; Chandur Sadarangani; Kelvin C Maliti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; skewing; cross current losses; radial magnetic forces; magnetic noise; asymmetrical rotor slots; eccentricity; stator vibration; two-dimensional fast fourier transform; finite element method; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Induction machines convert more than 55% of electrical energy into various other forms in industrial and domestic environments. Improved performance, especially by reduction of losses in induction machines hence can significantly reduce consumption of electricity. READ MORE

  7. 30. Enhancement of HIV-1 DNA immunogens

    Author : Anne Kjerrström Zuber; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1; DNA vaccination; regulatory genes; adjuvants; experimental HIV-1 model;

    Abstract : Human immunodeficiency virus type 1 eludes control by the immune response through a high degree of variability and immune escape mechanisms. Induction of a broad specific immune response is important to clear virus-infected cells. READ MORE
