  1. 11. Masseter and temporalis muscle thickness as assessed by ultrasound – a proof-of-concept study

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Jennifer Mattsson; Amanda Carlsson; [2020]
    Keywords : ultrasound; muscle thickness; TMD; masticatory muscles; proof of concept;

    Abstract : Syfte: Den aktuella studien är en metodstudie för att undersöka möjligheten att mäta förändringar i muskeltjocklek med ultraljud. Om detta fungerar kan metoden användas i studier som för närvarande undersöker om muskeltjocklek eller förändringar i muskeltjocklek vid användning är relaterade till orofacial smärta. READ MORE

  3. 12. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annica Gustafsson; [2019]
    Keywords : Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

    Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE

  4. 13. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mattheüs Lucassen; [2019]
    Keywords : Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Abstract : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. READ MORE

  5. 14. Virtual Sensing for Fatigue Assessment of the Rautasjokk Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Sara Lundman; Patrick Parnéus; [2018]
    Keywords : Fatigue Assessment; Virtual Sensing; Steel Bridges; Eurocode; Field Monitoring; Finite Element Model;

    Abstract : This thesis treats virtual sensing for fatigue assessment of steel bridges. The purpose is to develop avirtual sensing method to use in the fatigue assessment process. The aim for the virtual sensing method is to only depend on strain measurements located on the bridge structure. READ MORE

  6. 15. MEASUREMENT DRIVEN FATIGUE ASSESSMENT OF OFFSHORE WIND TURBINE FOUNDATIONS

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frauke Wilberts; [2017]
    Keywords : offshore wind turbine; monopile foundation; wind power; fatigue assessment;

    Abstract : The installed capacity of offshore wind turbines in Europe is increasing with the monopile being the most common type of foundation. During its lifetime an offshore wind turbine is exposed to high dynamic loads which eventually can result in the fatigue of the substructure. READ MORE
