  1. 1. A sensitivity analysis of the Winter-Kennedy method

    Författare :Binaya Baidar; Michel J. Cervantes; Mikael Sendelius; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; discharge; Winter-Kennedy; CFD; Sensitivity; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydropower is among the lowest-cost electrical energy sources due to its long lifespan and lower operation and maintenance cost. The hydro-mechanical components of hydropower plants generally last about four to five decades, then they are either overhauled or replaced. LÄS MER

  3. 3. The Skorohod problem and weak approximation of stochastic differential equations in time-dependent domains

    Författare :Thomas Önskog; Kaj Nyström; Leif Persson; Johan Tysk; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Skorohod problem; weak approximation; time-dependent domain; stochastic differential equations; parabolic partial differential equations; oblique reflection; stopped diffusions; Euler scheme; adaptive methods; sensitivity analysis; financial derivatives; Greeks ; MATHEMATICS; MATEMATIK; Mathematics; matematik;

    Sammanfattning : This thesis consists of a summary and four scientific articles. All four articles consider various aspects of stochastic differential equations and the purpose of the summary is to provide an introduction to this subject and to supply the notions required in order to fully understand the articles.

  4. 4. Radiation induced biomarkers of individual sensitivity to radiation therapy

    Författare :Sara Skiöld; Mats Harms-Ringdahl; Siamak Haghdoost; Mats Ljungman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; low dose ionizing radiation; radiation sensitivity; proteomics; whole blood; 8-oxo-dG; oxidative stress; acute adverse healthy tissue effects; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Fifty percent of solid cancers are treated with radiation therapy (RT). The dose used in RT is adjusted to the most sensitive individuals so that not more than 5% of the patients will have severe adverse healthy tissue effects. LÄS MER

  5. 5. Application of Differential Geometry to Elasticity and Corresponding Discrete Models

    Författare :Nina Lautersztajn-S.; Chalmers University of Technology; []
    Nyckelord :mechanical systems; differential geometry; isoparametric four-node elements; Lie groups; non-linear elasticity; elasticity; finite element method;

    Sammanfattning : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. LÄS MER
