  2. 1. The fW-mean filter framework for topology optimization and analysis of Friedrichs systems

    Author : Linus Hägg; Martin Berggren; Eddie Wadbro; Björn Engquist; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; topology optimization; filters; mathematical morphology; size control; minimum compliance problem; Friedrichs systems; well-posedness; variational formulations; linearized Euler’s equations; Galbrun’s equation; acoustics; Mathematics; matematik;

    Abstract : Part I. Topology optimization is the most general form of design optimization in which the optimal layout of material within a given region of space is to be determined. Filters are essential components of many successful density based topology optimization approaches. READ MORE

  6. 4. Life Cycle Energy Optimisation: A multidisciplinary engineering design optimisation framework for sustainable vehicle development

    Author : Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Mario Hirz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle energy optimisation; Multidisciplinary optimisation; Integrative design; Sustainable vehicle design; Functional conflicts; Vehicle aerodynamics; Battery energy storage systems; Robust design; Uncertainty propagation; Livscykelenergi; Fordonsdesign; Optimering; Tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.
