  3. 2. Modelling and optimization of gear shifting mechanism, Application to heavy vehicles transmission systems

    Författare :Muhammad Irfan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pareto optimization; synchronization; constraint Lagrangian formalism; sensitivity analysis; Generic synchronizer;

    Sammanfattning : Without an efficient transmission system the idea of an efficient vehicle is incomplete. During running of the vehicle especially in case of heavy vehicles the transmission system has to face different situations during which the system possibly can lose its efficiency. LÄS MER

  4. 3. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance

    Författare :Eric Berggren; Mats Berg; Laurent Schmitt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway track stiffness; maintenance; soil dynamics; measurement; simulation; vibration; Vehicle engineering; Farkostteknik;

    Sammanfattning : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. LÄS MER

  5. 4. Making architecture politically : from fresh conservatism to aestehtics as a form of politics

    Författare :Roemer Van Toorn; Jüri Soolep; Arie Graafland; Estonia Tallinn Estonian Academy of Arts; []
    Nyckelord :HUMANIORA; HUMANITIES; Architecture; Politics; Aesthetics; Architecture in the Netherlands; Secon Modernity; Society of the And; Fresh Conservatism; aesthetics; estetik; design; design; politikvetenskap; political science;

    Sammanfattning : This research comes from a particular place, a rather unique moment in the history of the Netherlands when Dutch architecture started to be much applauded for its radical approach and innovative design when the typhoon of another modernization swept across the globe. Architects, municipalities, investors, developers, companies, institutions, politicians, inhabitants, educators, researchers, critics and alike, were all thrown into a kind of experimental condition, one being both pragmatic and geographical.
