  1. 1. Meta-Languages and Semantics for Equation-Based Modeling and Simulation

    Författare :David Broman; Peter Fritzson; Jeremy Siek; Thomas Schön; Björn Lisper; Walid Taha; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meta-language; semantics; EOO; Modelica; equations; modeling; simulation; MKL; Computer science; Datalogi;

    Sammanfattning : Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and object-oriented modeling principles, enabling good reuse of models. LÄS MER

  3. 2. 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

  4. 3. Safety, Security, and Semantic Aspects of Equation-Based Object-Oriented Languages and Environments

    Författare :David Broman; Peter Fritzson; Henrik Nilsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modeling; Simulation; Equation-Based; Object-Oriented; Modelica; Type System; Semantics; Language Safety; Secure Simulation; Computer science; Datavetenskap;

    Sammanfattning : During the last two decades, the interest for computer aided modeling and simulation of complex physical systems has witnessed a significant growth. The recent possibility to create acausal models, using components from different domains (e.g., electrical, mechanical, and hydraulic) enables new opportunities. LÄS MER

  5. 4. Effective schools in a segregated landscape : Studies of academic achievement and psychological well-being among adolescents in Sweden

    Författare :Maria Granvik Saminathen; Bitte Modin; Sara Brolin Låftman; Stephanie Plenty; Torbjørn Torsheim; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; psychological health; adolescence; segregation; educational equity; school; academic achievement; structural equation modeling; multilevel modeling; folkhälsovetenskap; Public Health Sciences;

    Sammanfattning : Equitable educational opportunities necessitate equitable access to a favourable academic and social school environment. This thesis aims to explore the role of the school as an educational and social arena for the academic achievement and psychological well-being of lower secondary school students in Sweden. LÄS MER

  7. 5. Job characteristics, motivation and stress among information technology (IT) consultants

    Författare :Lars Göran Wallgren; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IT consultants; motivation; job demand; job control; stress; structural equation; modeling.;

    Sammanfattning : The general aim of the present thesis was to examine the relationship between job characteristics and perceived stress with motivators as the mediating variable in the information technology (IT) sector. This thesis is based on two empirical studies. LÄS MER
