  4. 3. On the relation between psychosocial work environment and musculoskeletal symptoms : a structural equation modeling approach

    Författare :Pernilla Larsman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychosocial work environment; felt stress; perceived fatigue; musculoskeletal symptoms; process models; mediation; moderation; structural;

    Sammanfattning : The aim of the present thesis was to investigate the relation between aspects of the psychosocial work environment and musculoskeletal symptoms including the testing of process models of the potential mediating mechanisms of felt stress and perceived fatigue, and the potential moderating mechanism of physical workload. This thesis is based on four empirical studies. LÄS MER

    Sammanfattning : First principle electronic structure theory is used to describe the effect of crystal binding on radiation detectors, electron transport properties, and structural damage induced by intense irradiation. A large database containing general electronic structure results to which data mining algorithms can be applied in the search for new functional materials, a case study is presented for scintillator detector materials.

  7. 5. Debugging and Structural Analysis of Declarative Equation-Based Languages

    Författare :Peter Bunus; Peter Fritzson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; software development; object-oriented; debugging; computer programming; debugging kernel prototypes; Computer science; Datavetenskap;

    Sammanfattning : A significant part of the software development effort is spent on detecting deviations between software implementations and specifications, and subsequently locating the sources of such errors. This thesis illustrates that is possible to identify a significant number of errors during static analysis of declarative object-oriented equation-based modeling languages that are typically used for system modeling and simulation.
