    Sammanfattning : Since the first generation of the Toyota Prius was introduced in December 1997, the number of Hybrid Electric Vehicles (HEVs) and pure Electric Vehicles (EVs) available in the market has increased substantially. The growing competition existent puts high demands on the electric system as well as the rest of the vehicle. LÄS MER

  5. 34. On Aircraft Conceptual Design : A Framework for Knowledge Based Engineering and Design Optimization

    Författare :Kristian Amadori; Petter Krus; Christopher Jouannet; Johan Ölvander; Ulf Sellgren; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : This thesis presents a design framework where analytical tools are linked together and operated from an efficient system level interface. The application field is aircraft conceptual design. Particular attention has been paid to CAD system integration and design optimization.Aircraft design is an inherently multidisciplinary process.

  7. 35. Marine propeller optimisation tools for scenario-based design

    Författare :Ioli Gypa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; marine propeller design; machine learning; scenario-based design; wind propulsion; interactive optimisation; user-code interaction; cavitation nuisance;

    Sammanfattning : The marine propulsion system is one of the most important components of a ship in order to cover the demanding operating needs of propulsion nowadays and to increase performance in a wide range of operating conditions. Marine propellers are designed with the purpose of matching the hull and machinery system, create the required thrust for the entire operational profile, and fulfil the techno-economical requirements that depend on the decision-making of several stakeholders.
