  1. 1. Machine Learning Based Methods for Virtual Validation of Autonomous Driving

    Författare :Tobias Johansson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AD Simulation; Virtual Validation; Sensor Error Modeling; Falsification; Autonomous Driving; Validation; Mixture Density Networks;

    Sammanfattning : During the last decade, automotive manufacturers have introduced increasingly capable driving automation functions in consumer vehicles. As the functionality becomes more advanced, the task of driving moves from the human to the car. Hence, making sure that autonomous driving (AD) functions are reliable and safe is of high importance.

  2. 2. Validation and application of objective measures of obesity and physical activity : studies in pregnant and non-pregnant adults and in infants

    Författare :Anna Gradmark; Paul W Franks; David Fields; Umeå universitet; []
    Nyckelord :physical activity; validation; body composition; abdominal adipose tissue; methods; accelerometer; pregnancy; insulin sensitivity; offspring;

    Sammanfattning : Background Excess adipose tissue and low physical activity are two major determinants for chronic diseases such as type 2 diabetes and cardiovascular disease.  Understanding these relationships requires accurate and precise measures of body composition and physical activity, and most existing observational studies lack such measures.

  3. 3. Simulation methods for hydropower flows : modeling and validation experiments

    Författare :T. Fredrik Engström; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : My research project aims for more accurate modeling of the flow in hydropower plants. By accurate modeling, it is possible to try different modifications on existing plants in an affordable manner. Also, entirely new designs can be tested before realization. Hydropower delivers almost 50% of Sweden's electricity demand with a production of 74 TWh. LÄS MER

  4. 4. Methods for Early Model Validation : Applied on Simulation Models of Aircraft Vehicle Systems

    Författare :Magnus Carlsson; Johan Ölvander; Hampus Gavel; Lars Eriksson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Simulation  models of physical systems, with or without control software, are widely used in the aeronautic industry in applications ranging from system development to verification and end-user training. With the main drivers of reducing the cost of physical testing and in general enhancing the ability to take early model-based design decisions, there is an ongoing trend of further increasing the portion of modeling and simulation.

  5. 5. Drug Analysis : Bioanalytical Method Development and Validation

    Författare :Mikaela Malm; Yngve Bergqvist; Anders Colmsjö; Uppsala universitet; []
    Nyckelord :Analytical chemistry; African trypanosomiasis; calibration model; chiral chromatography; dried blood spots; eflornithine; evaporative light-scattering detection; HIV AIDS; lamivudine; liquid chromatography; malaria; nevirapine; piperaquine; pneumonia; solid-phase extraction; sulfadoxine; sulfamethoxazole; validation; zidovudine; Analytisk kemi;

    Sammanfattning : This thesis describes bioanalytical methods for drug determination in biological matrixes, with drugs in focus used against diseases largely affecting low-income countries. Solid-phase extraction is used for sample cleanup, and processed samples are analyzed by liquid chromatography. LÄS MER
