    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.

  4. 22. Manufacturing management and decision support using simulation-based multi-objective optimisation

    Author : Leif Pehrsson; David Stockton; Ng Amos; Mats Jackson; Raouf Hamzaoui; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Management; Decision Support; simulation; Multi-objective; optimisation; Production systems; Teknik; Technology;

    Abstract : A majority of the established automotive manufacturers are under severe competitive pressure and their long term economic sustainability is threatened. In particular the transformation towards more CO2-efficient energy sources is a huge financial burden for an already investment capital intensive industry. READ MORE

  6. 24. A Model Based Approach to Robustness Analysis and Optimisation of Chromatography Processes

    Author : Niklas Jakobsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Langmuir; SMA; Optimisation; Robustness; Chromatography; Prepartive process scale; Modelling;

    Abstract : One of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. READ MORE

  7. 25. Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT

    Author : Marcus Söderberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; SPECT; PET; dosimetry; image quality; optimisation; dose reduction; automatic exposure control; contrast medium; phantom; image reconstruction; human observer;

    Abstract : The significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.
