  1. 1. Simulation based design : structural optimization at early design stages

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Marcus Redhe; Linköpings universitet.; Linköpings universitet.; [2001]

    Sammanfattning : The aim of this thesis is to evaluate and develop different modelling tools which can be used in the vehicle crashworthiness design process. These tools will improve the understanding of the vehicle behaviour and thus improve the crashworthiness of the vehicle. LÄS MER

  2. 2. Engine Optimized Turbine Design

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Nicholas Anton; KTH.; [2019]

  4. 4. Optimal Design of Experiments for the Quadratic Logistic Model

    Detta är en avhandling från Stockholm : Department of Statistics, Stockholm University

    Författare :Ellinor Fackle Fornius; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Logistic regression; D-optimality; c-optimality; Canonical design space; Maximum likelihood estimation; Sequential design; Stochastic approximation; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; statistik; Statistics;

    Sammanfattning : Optimal design of experiments for binary data is the topic of this thesis. A particular logistic model including a quadratic term in the linear predictor is considered. Determining an optimal design for this model is complicated by the fact that the optimal design is dependent on the unknown true parameters. LÄS MER

  5. 5. Preliminary Design Investigations for the Selection of Optimum Reaction Degree for 1st Stage of a High Pressure Gas Turbine

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Hina Noor; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 1D design; aerodynamic design parameters; flow kinematic; thermodynamics; rotor inlet temperature; cooled turbine; reaction degree; flow coefficient; stage loading;

    Sammanfattning : One-dimensional (1D) turbine design calculation phase requires a handful of input data and choice of design parameters to provide the blade flow path geometry along with the flow kinematics and thermodynamics properties at the blade mid-span. The choice of important aerodynamics design parameters namely reaction degree, nozzle guide vane NGV exit flow angle or flow coefficient and stage loading defines the mid-span flow velocity triangles.
