  1. 1. Hybrid Converters for HVDC Transmission

    Author : Panagiotis Bakas; Lennart Harnefors; Staffan Norrga; Hans-Peter Nee; Stephen Finney; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; High-voltage direct current HVDC ; hybrid alternate-common arm converter HACC ; hybrid converters; line-commutated converters LCCs ; modular multilevel converters MMCs ; thyristors; Hybrid alternate-common-arm converter HACC ; hybrid omvandlare; högspänd likströmsöverföring HVDC ; linjekommuterade omvandlare LCC ; modulära multinivåomvandlare MMC ; tyristorer; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The line-commutated converter (LCC) and the voltage-source converter (VSC) are the two main converter technologies utilized in high-voltage direct current (HVDC) transmission applications. Depending on the application requirements, one technology might be more advantageous than the other. READ MORE

  3. 3. The Duality of Moral Language : On Hybrid Theories in Metaethics

    Author : Stina Björkholm; Anandi Hattiangadi; Anders J. Schoubye; Mark Schroeder; Stockholms universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Metaethics; Hybrid Expressivism; Hybrid Descriptivism; Dynamic Descriptivism; Moral Disagreement; The Frege-Geach problem; The Practicality Problem; Philosophy; filosofi;

    Abstract : Moral language displays a characteristic duality. On the one hand, moral claims seem to be similar to descriptive claims: To say that an act is right (or wrong) seems to be a matter of making an assertion, thus indicating that the speaker has a moral belief about which she can be correct or mistaken.

  4. 4. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE
