  2. 21. Robust optimisation of structures : Evaluation and incorporation of variations in simulation based design

    Author : David Aspenberg; Larsgunnar Nilsson; Kjell Simonsson; Niels Olhoff; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis concerns the robustness of structures considering various uncertainties. The overall objective is to evaluate and develop simulation based design methods in order to find solutions that are optimal both in the sense of handling typical load cases and minimising the variability of the response, i.e. robust optimal designs.

  4. 22. Marine propeller optimisation tools for scenario-based design

    Author : Ioli Gypa; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

    Abstract : The development of biotechnological products is becoming more and more expensive. One type of protein attracting a great deal of attention in the biopharmaceutical industry is antibodies, which was used in this work. READ MORE

  7. 25. Parallel computing in model-based process engineering

    Author : Niklas Andersson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parameter estimation; Optimisation; Parameter selection; Model-based engineering;

    Abstract : Chemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. READ MORE
