  1. 1. Uncertainty quantification for offshore wind turbines

    University essay from KTH/Matematik (Avd.)

    Author : Ziming Wang; [2022]
    Keywords : wind energy; uncertainty propagation; polynomial chaos; Rosenblatt transformation; quadrature; regression; vindenergi; osäkerhetsutbredning; polynomkaos; Rosenblatt transformation; kvadratur; regression;

    Abstract : Wind energy is a field with a large number of uncertainties. The random nature of the weather conditions, including wind speed, wind direction, and turbulence intensity, influences the energy output and the structural safety of a wind farm, making its performance fluctuate and difficult to predict.

  3. 2. Development of a Design Tool in CAD for Fused Deposition Modelled Coolant Nozzles in Grinding : Design automation of coolant nozzles

    University essay from Linköpings universitet/Produktrealisering

    Author : Joachim Neguembor; [2022]
    Keywords : Design Automation; Fused Deposition Modelling; DOE; Grinding Coolant; Grinding Process; Coolant Supply in Grinding; Design of Experiment; Surrogate Model Optimization; Coolant Nozzle; Design Automering; Slipande Bearbetning; Kylvätskemunstycke;

    Abstract : This thesis covers the process of automating the design of coolant nozzles used for cylindrical grinding. Coolant nozzles are used to supply coolant, an oil and water mixture used to cool the metal workpiece and lubricate the grinding wheel. In the automotive industry, grinding is used to reduce the surface roughness of the workpiece. READ MORE

  4. 3. Design Optimization in Gas Turbines using Machine Learning : A study performed for Siemens Energy AB

    University essay from Linköpings universitet/Programvara och system

    Author : Berggren Mathias; Sonesson Daniel; [2021]
    Keywords : Computer Science; Design Optimization; DO; MDO; Surrogate Models; Surrogates; Response Surface Methods; Metamodels; Metamodeling; Machine Learning; ML; FEA; Finite Element Analysis; FEM; Finite Element Method;

    Abstract : In this thesis, the authors investigate how machine learning can be utilized for speeding up the design optimization process of gas turbines. The Finite Element Analysis (FEA) steps of the design process are examined if they can be replaced with machine learning algorithms. READ MORE

  5. 4. Dynamic Finite Element Modelling of a Fall on the Hip

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Nils Nyberg; [2021]
    Keywords : Hip Fracture; Finite Element Modeling; Finite Element; Femur Fracture; Sideways Fall; Technology and Engineering;

    Abstract : Assessing the risk of future femur fracture is an important step in preventing this serious and common injury. The current methods to predict the fracture risk are typically based on bone mineral density measurement, used as a surrogate for femoral strength. READ MORE

  6. 5. How robust is water quality determination with optical measurements for highly polluted agricultural waters?

    University essay from SLU/Dept. of Soil and Environment

    Author : Honorine Uwera; [2020]
    Keywords : turbidity; suspended sediments; dissolved organic matter; optical measurements;

    Abstract : Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. To characterize suspended sediments (SS) and dissolved organic matter (DOM) in surface water some optical measurements have been used (absorbance and fluorescence spectroscopy). READ MORE
