  1. 11. Active Muscle Responses in a Finite Element Human Body Model

    Författare :Jonas Östh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedback control; autonomous braking; finite element; human body model; active muscle; posture maintenance; reflexive response;

    Sammanfattning : The development of automotive safety systems is moving towards an integration of systems thatare active before and during an impact. Consequently, there is a need to make a combinedanalysis of both the pre-crash and the in-crash phases, which leads to new requirements forHuman Body Models (HBMs) that today are used for crash simulations.

  3. 12. A dispatch procedure for traffic control of a fleet of remote-controlled automatic LHDS in underground hard rock mines : modelling approach is based on simulation

    Författare :Nikolaos Vagenas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : A concept for automating Load-Haul-Dump (LHD) vehicles has stimulated considerable interest in the Swedish mining industry. In this concept, tramming and dumping operations of an LHD should be automatic. During loading, an operator from a control room fills the bucket of a vehicle via remote-control aided by a television system. LÄS MER

  4. 13. Optimized Pacing Strategies in Cross-Country Skiing and Time-Trial Road Cycling

    Författare :David Sundström; Mats Tinnsten; Peter Carlsson; John Rasmussen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; numerical simulation; equations of motion; MMA; cross-country skiing; cycling; Optimering; numerisk simulering; rörelseekvationer; MMA; längdskidåkning; cykling;

    Sammanfattning : This thesis is devoted to the analysis and optimization of pacing strategies in cross-country skiing and time-trial road cycling. In locomotive sports, it is well known that variable pacing strategies using changes in the distribution of power output are beneficial when external forces vary along the way. LÄS MER

  5. 14. Model-based Methods in Motion Capture

    Författare :Kjartan Halvorsen; Antonie J. van den Bogert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik; Systemanalys; Systems Analysis;

    Sammanfattning : This thesis concerns the use of kinematic models and shape models to solve the problem of estimating the motion of articulated objects from image data. The data considered in the first part of the thesis are trajectories of 3D feature points (markers). In the second part, image sequences are considered. LÄS MER

  7. 15. Numerical optimization of pacing strategies in locomotive endurance sports

    Författare :David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pacing strategy; optimization; numerical simulation; equations of motion; method of moving asymptotes; cross-country skiing; cycling; Farthållningsstrategi; optimering; numerisk simulering; rörelseekvationer; method of moving asymptotes; längdskidåkning; cykling;

    Sammanfattning : This thesis is devoted to the optimization of pacing strategies in two locomotive endurance sports; cross-country skiing and road cycling. It has been established that constant pace and variable power distributions are optimal if purely mechanical aspects of locomotion are considered in these sports. LÄS MER
