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

   Författare :Tobias Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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.

3. 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.

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

   Författare :T. Fredrik Engström; Luleå tekniska universitet; []
   Nyckelord :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

5. 4. On Statistical Methods for Safety Validation of Automated Vehicles

   Författare :Daniel Åsljung; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; performance evaluation; extreme value theory; Automotive; validation; automated vehicles; simulation; verification; automated driving systems;

   Sammanfattning : Automated vehicles (AVs) are expected to bring safer and more convenient transport in the future. Consequently, before introducing AVs at scale to the general public, the required levels of safety should be shown with evidence. However, statistical evidence generated by brute force testing using safety drivers in real traffic does not scale well. LÄS MER

7. 5. 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.
