  1. 21. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System

    Författare :Sasa Trajkovic; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressor; Air-motor; Pneuamtc; Pneumatic-hybrid; VVT; Valve; regenerative; Hybrid; Air;

    Sammanfattning : 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 IC engines could be saved, the fuel economy would improve. LÄS MER

  3. 22. Effekten av effekten. Elanvändning och laststyrning i elvärmda småhus ur kund- och företagsperspektiv. Fallstudier

    Författare :Kerstin Sernhed; Institutionen för energivetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energianvändning; tariffer; effekt; laststyrning; småhus;

    Sammanfattning : Electricity must be produced at the same time as it is used. This necessitates flexibility in the electricity production and electricity networks. Until recently, the increase in electricity demand and peak power demand has been met by expansion of the electricity production. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 24. Dissection of virus-host cell interactions in the early response to infection

    Författare :Marc D Panas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Stress granules (SG) are dynamic RNA/protein assemblies in the cytoplasm of the cell, formed under conditions of oxidative stress, heat shock or viral infections. These stress conditions trigger a sudden translational arrest, leading to a rapid switch of translation from housekeeping genes to stress-related factors. LÄS MER

  7. 25. Studies of MISiC-FET sensors for car exhaust gas monitoring

    Författare :Helena Wingbrant; Anita Lloyd Spetz; Martin Eickhoff; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; field effect sensor; gas detection; selective catalytic reduction; lambda; cold start; ammonia; silicon carbide; engine exhaust; Physics; Fysik;

    Sammanfattning : The increasing size of the car fleet makes it important to find ways of lowering the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from emissions at cold start, in the case when gasoline is utilized, and high NOx emissions and particulates from diesel engines. LÄS MER
