  1. 16. On Optimal Mission Planning for Vehicles over Long-distance Trips

    Författare :Ahad Hamednia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic dynamic programming; Optimal control; Logistics planning; Thermal and charging management; Model predictive control; Mission planning;

    Sammanfattning : This thesis proposes a mission planner for vehicles over long-distance trips, for finding the optimal trade-off between trip time, energy efficiency, and driver comfort, subject to road information, traffic situations, and weather conditions. The mission planner consists of three components, i.e. LÄS MER

  3. 17. Sequential Monte Carlo for inference in nonlinear state space models

    Författare :Johan Dahlin; Thomas Schön; Fredrik Lindsten; Adam M. Johansen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nonlinear state space models (SSMs) are a useful class of models to describe many different kinds of systems. Some examples of its applications are to model; the volatility in financial markets, the number of infected persons during an influenza epidemic and the annual number of major earthquakes around the world.

  4. 18. On Numerical Descriptions of Road Transport Missions

    Författare :Pär Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; Transport mission description; CO$_2$-emission; full vehicle simulation; road format; energy consumption; operating cycle;

    Sammanfattning : This thesis addresses some issues of current interest in energy consumption prediction through simulation. First, we review the situation for rating, regulation and legislation of CO$_2$-emissions for cars and heavy vehicles. LÄS MER

  5. 19. Towards Efficient Monte Carlo Calculations in Reactor Physics : Criticality, Kinetics and Burnup Problems

    Författare :Ignas Mickus; Jan Dufek; Andrea Zoia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kärnenergiteknik; Nuclear Engineering;

    Sammanfattning : This thesis presents a compilation of work focused on Monte Carlo crit-icality, kinetics and burnup calculations in reactor physics. Performing suchcalculations usually comes at a high computing cost. Therefore, the main mo-tivation behind the presented work is lowering the computing cost of MonteCarlo calculations. LÄS MER

  7. 20. Cost-efficient carbon abatement strategies in the EU with specific focus on forest carbon sequestration

    Författare :Miriam Munnich; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Forests can contribute to the reduction of carbon emissions by storing carbon in standing biomass or in products made of wood. Alternatively, harvested biomass can be used as bioenergy and replace fossil fuels. This thesis analyses the cost-efficiency of introducing forest carbon sequestration (FCS) into EU climate policy.
