  2. 1. On Degree Variance in Random Graphs

    Author : Jan Hagberg; Ove Frank; Tom A.B. Snijders; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Degree Sequences; Uniform Random Graphs; Bernoulli Graphs; Degree Moments; Degree Statistics; Degree Variance; Gamma Approximation; Centrality Testing; Integer Sequences; Statistics; Statistik;

    Abstract : This thesis is concerned with degree moments and degree variance in random graphs. The degree of vertex i in a graph is the number of edges incident to vertex i.In the first paper, degree moments and functions of degree moments are investigated for three random graph models.

  4. 2. Bayesian Inference in Structural Second-Price Auctions

    Author : Bertil Wegmann; Mattias Villani; Samita Sareen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asymmetry; Bid function approximation; Common values; Gamma model; Gaussian model; Markov Chain Monte Carlo; Private values; Variable selection; Internet auctions; Statistics; Statistik; Statistics; statistik;

    Abstract : The aim of this thesis is to develop efficient and practically useful Bayesian methods for statistical inference in structural second-price auctions. The models are applied to a carefully collected coin auction dataset with bids and auction-specific characteristics from one thousand Internet auctions on eBay. READ MORE

  5. 3. Alternative Methods for Assessment of Split Renal Function

    Author : Henrik Björkman; Anders Magnusson; Jonas Wadström; Torbjörn Andersson; Uppsala universitet; []
    Keywords : Radiology; Split renal function; Live kidney donor; CT; Renography; Dynamic MRI; Renal volume; Respiratory triggering; Radiologisk forskning;

    Abstract : Living kidney donation is a clinical situation with unique features in the sense that healthy individuals voluntarily expose themselves to certain risks and inconveniences. Therefore, eliminating as much of the associated discomfort as possible is crucial. READ MORE

  6. 4. Nonlinear Optical Properties of Fullerenes, Oligomers, and Solutions

    Author : Patrick Norman; Hans Ågren; David M. Bishop; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This work presents development and applications of modern tools in ab initio quantum chemistry for obtaining linear and nonlinear response properties of molecules in the gas phase and in solution. The external perturbing fields are primarily electric in nature with frequencies in the optical region. READ MORE

  7. 5. Essays in Quantitative Finance

    Author : Patrik Karlsson; Nationalekonomiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; credit valuation adjustment CVA ; derivative pricing; interest rate derivatives; Monte Carlo simulation;

    Abstract : This thesis contributes to the quantitative finance literature and consists of four research papers.Paper 1. This paper constructs a hybrid commodity interest rate market model with a stochastic local volatility function that allows the model to simultaneously fit the implied volatility of commodity and interest rate options.
