  2. 1. Linear response theory : from black hole thermalization to Weyl semimetals

    Author : Jorge Laraña Aragón; Bo Sundborg; Edwin Langman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. READ MORE

  4. 2. The Measurement of Subjective Well-Being: Item Response Theory, Classical Test Theory, and Multidimensional Item Response Theory

    Author : Ali Al Nima; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Life Satisfaction; Negative Affect; Positive Affect; Harmoni in Life Subjective Well-Being; Item Response Theory; Classical Test Theory; Multidimensional Item Response Theory.;

    Abstract : For over 35 years, modern science has conceptualized happiness as subjective well-being, which has until recently been understood as a dual construct consisting of an affective component (positive and negative affect) and a cognitive component (life satisfaction). Nevertheless, for the last five years, theoretical work and both quantitative and qualitative empirical work have suggested that the concept of subjective well-being omits both a lay and an Eastern way of understanding happiness.

  5. 3. Some binary response situations : theory and applications

    Author : Karin Dahmström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In a binary response situation we are studying an event which either occurs or does not occur. Such situations are treated in the following five reports. In report I, there is a review of different statistical models and analysis methods for, in particular, nonexperimental surveys. READ MORE

  6. 4. Extending relativistic linear response theory to address solvent effects

    Author : Joel Creutzberg; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Response theory; Polarizable embedding; Complex Polarization Propagator; Relativistic effects;

    Abstract : The central aim of this thesis is to derive, implement and test new methods to calculate various types of spectroscopies of compounds containing heavy elements in an aqueous environment. Methods that can target such systems have to consider the following:(i) It is crucial to take relativistic effects into account. READ MORE

  7. 5. Fatigue Assessment and Extreme Response Prediction of Ship Structures

    Author : Wengang Mao; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fatigue assessment; extreme response; rainflow; narrow-band approximation; Laplace Moving Average model; transformed Gaussian; zero up-crossing response frequency; significant wave height; safety index; upcrossing spectrum; long term cumulative distribution function; ship routing.; transformed Gaussian;

    Abstract : In this thesis, a simplified narrow-band approximation model is proposed to estimate fatigue damage of ship structures, and an efficient method for extreme response predictions is also developed using upcrossing spectrums of ship responses. The proposed fatigue model includes two main parameters, significant stress range hs and zero upcrossing frequency fz. READ MORE
