  2. 16. Calculated Potential Energy Surfaces and Vibrational Analysis

    Author : Niclas Forsberg; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Benzene; HCO; NEMO; Imaginary Level Shift; Double Harmonic Approximation; Potential Energy Surface; CASPT2; Franck-Condon Factors; CASSCF; p-Benzosemiquinone; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : The focus of this thesis is on the calculation of potential energy surfaces and on the study of vibrational properties. For example: - We have developed a new method for calculation of Franck-Condon factors. - We have calculated full energy surfaces of the ground (X2A’) the excited (B2A’) states of the formyl radical.

  4. 17. A Bayesian approach to retrospective detection of change-points in road surface measurements

    Author : Fridtjof Thomas; Urban Hjort; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Change-point detection; retrospective view; autoregressive processes; minimal imaginary training sample; road surface measurements; international roughness index; rutting; Laser-RST vehicles; road maintenance; pavement management; statistik; Statistics;

    Abstract : First-order autoregressive processes are analysed for sudden changes in parameter value. In its most general form, a multivariate vector of measurements is allowed, and no prior knowledge about the involved parameters is required. READ MORE

  5. 18. On two-dimensional conformal geometry related to the Schramm-Loewner evolution

    Author : Lukas Schoug; Fredrik Viklund; Nathanaël Berestycki; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conformal invariance; scaling; random fractals; Mathematics; Matematik;

    Abstract : This thesis contains three papers, one introductory chapter and one chapter with overviews of the papers and some additional results. The topic of this thesis is the geometry of models related to the Schramm-Loewner evolution.In Paper I, we derive a multifractal boundary spectrum for SLEκ(ρ) processes with κ.. READ MORE

  6. 19. Periodized Thermal Greens Functions and Applications

    Author : Andro Sabashvili; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; Greens function; graphene; DMFT; RPA; GW;

    Abstract : This work describes a new formalism for Fermionic thermal Greens functions that are discretized in imaginary time. The discretization makes the thermal Greens function periodic in imaginary (Matsubara) frequency space and requires a generalisation of the Dyson equation and Luttinger-Ward-Baym-Kadanoff functional.

  7. 20. Before Audit : Essays on the necessity of imagination

    Author : Mohamed Mahieddine; Mikael Holmgren Caicedo; Gustav Johed; Henri Guénin; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Auditing; Mimesis; Possibilities; The Audit Society; Imagination; Ontology; Verification; Business Administration; företagsekonomi;

    Abstract : The audit society idea has radically influenced our conception of auditing with its critique of the functionalist view that sees auditing as an objective verification of steady facts. The audit society thesis argues that auditing is a ‘technology of representation’ and auditors are involved in the construction of facts they are supposed to verify. READ MORE
