  1. 16. Kinematic analysis of traumatic brain injuries in boxing using finite element simulations

    Master-uppsats, KTH/Medicinsk teknik

    Författare :Xuelong Fan; [2016]
    Nyckelord :Finite element simulation; kinematic analysis; human arm modeling; boxing;

    Sammanfattning : The purpose of the thesis was to analyze and evaluate the head injuries due to a striking in a boxing match by LS-DYNA. A simplified arm model was built up and was equipped with three segments which were linked with two spherical joints. LÄS MER

  3. 17. Realtidsmätning inom fastighetsbildning med "Precise Point Positioning" (PPP)

    Kandidat-uppsats, Högskolan Väst/Avdelningen för data-, elektro- och lantmäteriteknik

    Författare :Victor Kvarnström; Jessica Wallerström; [2016]
    Nyckelord :GNSS; Global Navigate Satellite System; RTK; Real Time Kinematic; PPP; Precise Point Positioning; RTX; Real Time Extended; Real property; RIX 95; Real Time Measurement; GNSS; Global Navigate Satellite System; RTK; Real-Time Kinematic; PPP; Precise Point Positioning; RTX; Real-Time Extended; Fastighetsbildning; RIX 95; Realtidsmätning;

    Sammanfattning : Vid GNSS-positionering i samband med fastighetsbildningsåtgärder används vanligtvis den traditionella RTK-mätningen (Real-Time Kinematic) via SWEPOS nätverks-RTK-tjänst. Denna tjänst kräver mobiltelefontäckning eller motsvarande tvåvägskommunikation, vilket kan vara problematiskt inom områden med bristfällig mobiltelefontäckning. LÄS MER

  4. 18. Efficient Modeling of a Flexible Beam in Dymola using Coupled Substructures in a Floating Frame of Reference Formulation

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Anders Ericsson; Anton Kjellander; [2015]
    Nyckelord :Euler Bernoulli Beam Theory; Floating Frame of Reference Formulation; Craig-Bampton Method; Flexible Bodies; Dymola; Modelica; Technology and Engineering;

    Sammanfattning : In this Master Thesis a three dimensional Euler-Bernoulli beam model was implemented in the simulation software Dymola. The beam model is based on the Floating Frame of Reference formulation combined with the Craig-Bampton method. LÄS MER

  5. 19. Prediction of the machine tool errors under quasi-static load : Developing methodology through the synthesis of bottom-up and top-down modeling approach

    Master-uppsats, KTH/Industriell produktion

    Författare :Károly Szipka; [2015]
    Nyckelord :;

    Sammanfattning : One of the biggest challenges in the manufacturing industry is to increase the understanding of the sources of the errors and their effects on machining systems accuracy. In this thesis a new robust empirical evaluation method is developed to predict the machine tool errors under quasi-static load including the effect of the variation of stiffness in the workspace, the geometric and the kinematic errors.

  7. 20. Modeling and measurement of geometric error of machine tools : Methodology and implementation

    Master-uppsats, KTH/Industriell produktion

    Författare :Theodoros Laspas; [2014]
    Nyckelord :;

    Sammanfattning : One of the main performance criteria for a machine tool is its ability to manufacture dimensionally and geometrically accurate parts. In this context evaluation of the geometric and kinematic accuracy of machine tools is important for achieving a high accuracy of machine parts. LÄS MER
