  1. 1. Finite Element Procedures for the Numerical Simulation of CRack Propagation and Bilateral Contact

    Författare :Per Heintz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis concerns finite element methods for the numerical simulation of crack propagation including contact formulations for the contact between deformable bodies. The classical integral formulations for theenergy release rate at crack growth are considered and adaptive algorithms are developed. LÄS MER

  4. 3. Health economic aspects of diabetic retinopathy

    Författare :Emelie Heintz; Lars-Åke Levin; Ann-Britt Wiréhn; Josephine Mauskopf; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; diabetic retinopathy; health economic evaluations; quality-adjusted life years; costs; quality of life; prevalence;

    Sammanfattning : To ensure that the resources of the health care sector are used effectively, new technologies need to be evaluated before implementation to examine if they generate health outcomes at an acceptable cost. This information can be collected by performing health economic evaluations in which the costs and health outcomes of different technologies are compared. LÄS MER
