  2. 1. Molecular Quadratic Response Properties with Inclusion of Relativity

    Author : Johan Henriksson; Patrick Norman; Juha Vaara; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativistic quantum chemistry; molecular physics; clamping levels; four-component Hartree-Fock theory; Kohn-Sham density functional theory; response theory; nonlinear optics; second-harmonic generation; two-photon absorption; excited state properties; optical power limiting; Computational physics; Beräkningsfysik;

    Abstract : This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior. READ MORE

  4. 2. Optimal Design of Experiments for the Quadratic Logistic Model

    Author : Ellinor Fackle Fornius; Hans Nyquist; Christos Kitsos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Logistic regression; D-optimality; c-optimality; Canonical design space; Maximum likelihood estimation; Sequential design; Stochastic approximation; Statistics; Statistik; statistik; Statistics;

    Abstract : Optimal design of experiments for binary data is the topic of this thesis. A particular logistic model including a quadratic term in the linear predictor is considered. Determining an optimal design for this model is complicated by the fact that the optimal design is dependent on the unknown true parameters. READ MORE

  5. 3. Determination and use of radiobiological response parameters in radiation therapy optimization

    Author : Panayiotis Mavroidis; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Radiotherapy optimization; tumour control; normal tissue complications; radiobiological treatment planning; biological models; dose-response parameters;

    Abstract : Optimization of radiation therapy is critically dependent on the use of patient related information. For this reason, radiobiological models describing the dependence of tumour and normal tissue responses on the irradiated volume and the dose-time-fractionation schedule should be introduced.

  6. 4. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications

    Author : Jan Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind turbine; voltage source converter; voltage angle control; frequency response; vector current control; grid-connected; forced-commutated; measurements;

    Abstract : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. READ MORE

  7. 5. Cubic Response Theory and the Electromagnetic Properties of Ground and Excited States

    Author : Dan Jonsson; Aage E. Hansen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is devoted to the study of analytical response theory up to third order and its application to electromagnetic properties of ground and excited states. Computationally tractable expressions for the cubic response function for SCF and MCSCF wave functions have been derived and implemented in a computer code. READ MORE
