  2. 1. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study

    Author : Chen Yang; Lundqvist Per; Carlos Infante Ferreria; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. READ MORE

  4. 2. Environmental policy integration in bioenergy : policy learning across sectors and levels?

    Abstract : A central principle within UN and EU policy is environmental policyintegration (EPI), aiming at integrating environmental aspirations, targetsand requirements into sector policy in order to promote sustainabledevelopment. The focus of this study is EPI in bioenergy policy. READ MORE

  5. 3. Pre-Flight Development of the PoGOLite Pathfinder

    Author : Mózsi Kiss; Mark Pearce; Gottfried Kanbach; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Astropartikelfysik;

    Abstract : The Polarized Gamma-ray Observer (PoGOLite) is a balloon-borne instrument that will measure gamma-ray polarization in the energy range 25-80 keV from astronomical sources such as pulsars, accretion discs and jets from active galacticnuclei. The two additional parameters provided by such observations, polarizationangle and degree, will allow these objects to be studied in a new way, providing information about their emission mechanisms and geometries.

  7. 5. Fuel-Efficient Distributed Control for Heavy Duty Vehicle Platooning

    Author : Assad Alam; Karl Johansson; Ather Gattami; Roy Smith; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Heavy Duty Vehicle; Platooning; Fuel; Reachability; Game Theory;

    Abstract : Freight transport demand has escalated and will continue to do so as economiesgrow. As the traffic intensity increases, the drivers are faced with increasinglycomplex tasks and traffic safety is a growing issue. Simultaneously, fossil fuel usageis escalating. Heavy duty vehicle (HDV) platooning is a plausible solution to theseissues. READ MORE
