  1. 1. 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

  3. 2. The operating cycle representation of road transport missions

    Författare :Luigi Romano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; transport application; road mission; probability distributions; stochastic processes; energy estimation;

    Sammanfattning : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon.

  4. 3. Mathematical modelling of operating cycles for road vehicles

    Författare :Luigi Romano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy estimation; transport application; operating cycle; autoregressive models; road mission; stochastic models;

    Sammanfattning : Difficulties that commercial vehicles are facing in meeting regulation standards require ad-hoc solutions. Emissions can be dramatically lowered if the characteristics of the transport application are known in advance. LÄS MER

  5. 4. Operating cycle representations for road vehicles

    Författare :Pär Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

    Sammanfattning : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. LÄS MER

  7. 5. Heavy-ion transport codes for radiotherapy and radioprotection in space

    Författare :Davide Mancusi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charge-changing cross sections; transport codes; radiotherapy; Monte-Carlo codes; heavy ions; radioprotection in space;

    Sammanfattning : Simulation of the transport of heavy ions in matter is a field of nuclear science that has recently received attention in view of its importance for some relevant applications. Accelerated heavy ions can, for example, be used to treat cancers (heavy-ion radiotherapy) and show some superior qualities with respect to more conventional treatment systems, like photons (x-rays) or protons.
