  2. 16. Approaching well-founded comprehensive nuclear data uncertainties : Fitting imperfect models to imperfect data

    Author : Petter Helgesson; Henrik Sjöstrand; Helmut Leeb; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evaluated nuclear data; uncertainty propagation; uncertainty quantification; model defects; Gaussian processes; TALYS; TENDL; covariances.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : Nuclear physics has a wide range of applications; e.g., low-carbon energy production, medical treatments, and non-proliferation of nuclear weapons. Nuclear data (ND) constitute necessary input to computations needed within all these applications. READ MORE

  4. 17. Machine learning with state-space models, Gaussian processes and Monte Carlo methods

    Author : Andreas Svensson; Thomas B. Schön; Fredrik Lindsten; Carl Edward Rasmussen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; State-space models; Gaussian processes; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Numbers are present everywhere, and when they are collected and recorded we refer to them as data. Machine learning is the science of learning mathematical models from data. Such models, once learned from data, can be used to draw conclusions, understand behavior, predict future evolution, and make decisions. READ MORE

  5. 18. Environment support for building structured mathematical models

    Author : Johan Herber; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is about two topics. It describes a high-level programming environment for scientific computing, called ObjectMath, and several contributions to this environment. It also analyses the concept of software development environment architecture, in particular with respect to the ObjectMath environment. READ MORE

  6. 19. Models and Critical Maneuvers for Road Vehicles

    Author : Kristoffer Lundahl; Lars Nielsen; Timothy Gordon; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : As manufacturers are pushing their research and development toward more simulation based and computer aided methods, vehicle dynamics modeling and simulation become more important than ever. The challenge lies in how to utilize the new technology to its fullest, delivering the best possible performance given certain objectives and current restrictions. READ MORE

  7. 20. Having a New Pair of Glasses : Applying Systemic Accident Models on Road Safety

    Author : Yu-Hsing Huang; Erik Hollnagel; Pietro Carlo Cacciabue; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accident model; road safety; accident prevention; accident analysis; Cognitive science; Kognitionsvetenskap;

    Abstract : The main purpose of the thesis is to discuss the accident models which underlie accident prevention in general and road safety in particular, and the consequences of relying on a particular model have for actual preventive work. The discussion centres on two main topics. READ MORE
