  1. 21. Inside the black box of workplace interventions : investigating the influence of context and process on outcomes

    Författare :Hanna Augustsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Staff working in healthcare and residential care for older people are continuously required to learn and develop competencies to keep up with medical, technological and social developments. At the same time, they experience a work situation generally characterized by high demands. LÄS MER

  3. 22. Data-driven Ship Performance Models - - Emphasis on Energy Efficiency and Fatigue Safety

    Författare :Xiao Lang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semi-empirical; energy efficiency; fatigue assessment; grey-box; full-scale measurements; speed-power relationship; added resistance due to waves; ship performance; machine learning;

    Sammanfattning : Due to digitalization in the maritime industry, a huge amount of ship operation-related data has been collected. The main objective of this thesis is to exploit machine learning/big data analytics to build data-driven ship performance models, focusing on speed-power relationship modeling, and fatigue accumulation assessment during a ship’s operation at sea.

  4. 23. A Study of Adaptive Control of Missiles

    Författare :Gert Malmberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive control; Missiles;

    Sammanfattning : The report assesses the use of adaptive control schemes to the guidance and control problem of tactical missiles. This application is basically characterized by the fact that the unerlying equations are well known and apriori information of parameters can be obtained, i.e. LÄS MER

  5. 24. Uncertainties in Neural Networks : A System Identification Approach

    Författare :Magnus Malmström; Fredrik Gustafsson; Isaac Skog; Daniel Axehill; Håkan Hjalmarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; uncertainty; system identification;

    Sammanfattning : In science, technology, and engineering, creating models of the environment to predict future events has always been a key component. The models could be everything from how the friction of a tire depends on the wheels slip  to how a pathogen is spread throughout society. LÄS MER

  7. 25. Tools for Discovery, Refinement and Generalization of Functional Properties by Enumerative Testing

    Författare :Rudy Matela Braquehais; University of York; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents techniques for discovery, refinement and generalization of properties about functional programs. These techniques work by reasoning from test results: their results are surprisingly accurate in practice, despite an inherent uncertainty in principle. LÄS MER
