  1. 16. Toward motion-capture-based digital human modelling

    Författare :Ali Keyvani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion Capture Data Management; Human Motion Simulation; Digital Human Modeling; Virtual Production Tools;

    Sammanfattning : Digital Human Models (DHMs) are getting more applicable in the simulation of human postures/actions inside virtual production systems. Despite the existence of various modeling techniques, simulated motions are still looking unrealistic. LÄS MER

  3. 17. Automatic generation of a view to geographical database

    Författare :Mats Dunkars; KTH; []
    Nyckelord :Digital cartography; automatic cartographic generalization; object oriented modeling;

    Sammanfattning : This thesis concerns object oriented modelling and automatic generalisation of geographic information. The focus however is not on traditional paper maps, but on screen maps that are automatically generated from a geographical database. LÄS MER

  4. 18. Integration of database technology and multibody system analysis

    Författare :Claes Tisell; KTH; []
    Nyckelord :machine element; dynamic systems; multibody system kanes equations of motion; simulation; submodel; functional assembly;

    Sammanfattning : The design process includes many different activities inwhich various computational mechanics tools are used forbehaviour modelling of mechanical systems and their buildingblocks, e.g. machine elements. These tools usually supportlarge and complex models and they produce large quantities ofdata with a high degree of complexity. LÄS MER

  5. 19. Modelling and simulation of simultaneous forming and quenching

    Författare :Greger Bergman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The objective of this thesis is to develop and evaluate numerical methods for modelling and simulation of simultaneous forming and quenching within an integrated product development environment. Simultaneous forming and quenching, also referred to as hot-stamping, is a manufacturing process for high strength automotive components such as side impact protection beams. LÄS MER

  7. 20. Modelling and Quality Assessment of Atrial Fibrillatory Waves

    Författare :Mikael Henriksson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECG; signal processing; atrial fibrillation; signal quality; catheter ablation; atrial fibrillatory waves; f-waves;

    Sammanfattning : This doctoral thesis revolves around the analysis of electrocardiogram (ECG) signals during atrial fibrillation (AF). Special emphasis is put on the atrial fibrillatory waves, sometimes called the f-waves, which is the ECG component reflecting the electrical activity of the atria. LÄS MER
