  2. 21. SiC Varactors for Dynamic Load Modulation of Microwave Power Amplifiers

    Author : Christer Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear characterization; varactors; active load-pull; power; microwave; amplifier; dynamic load modulation; SiC; energy efficiency;

    Abstract : The rapid consumer adoption of mobile services is leading to an exponential growth in wireless data traffic. In order to accommodate more concurrent high data-rate users, the required complexity of transmitting radio base station (RBS) power amplifiers (PAs) is increasing. READ MORE

  4. 22. Load Modelling for Fatigue Assessment of Vehicles - a Statistical Approach

    Author : Magnus Karlsson; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fatigue; customer correlation; road load modelling; design of experiments; vehicle independent load models; lateral loads; road load modelling;

    Abstract : A way of modelling loads in customer usage for fatigue life considerations of vehicles is discussed. The starting point is lateral vehicle loads acting on trucks. Customer usage is described by using road classification. READ MORE

  5. 23. Gasoline Engine HCCI Combustion - Extending the high load limit

    Author : Daniel Dahl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NVO; stratified charge; gasoline engine; high load; knock.; HCCI; stoichiometric; CAI; ringing; SCCI;

    Abstract : There is an increasing global focus on reducing emissions of greenhouse gases.For the automotive industry this means reducing CO2 emissions of the vehiclesmanufactured, which is synonymous with reducing their fuel consumption oradapting them for using renewable fuels. READ MORE

  6. 24. Interruptible Load Services in Deregulated Power Market

    Author : Anh Tuan Le; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion management; deregulated electricity market; ancillary services; optimal power flow; reserve generation; interruptible load management;

    Abstract : Since the nineties decade, many electric utilities world-wide have been under restructuring from vertically integrated functioning to deregulated open-market system. In the erstwhile vertically integrated utilities, the system operator sought to maximize the social welfare with distributional equity (meeting the load at all time) as the main criteria, for the system as a whole.
