  1. 1. Contributions to Estimation and Testing Block Covariance Structures in Multivariate Normal Models

    Detta är en avhandling från Stockholm : Department of Statistics, Stockholm Univeristy

    Författare :Yuli Liang; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistik; Statistics; Block circular symmetry; covariance parameters; explicit maximum likelihood estimator; likelihood ratio test; restricted model; Toeplitz matrix;

    Sammanfattning : This thesis concerns inference problems in balanced random effects models with a so-called block circular Toeplitz covariance structure. This class of covariance structures describes the dependency of some specific multivariate two-level data when both compound symmetry and circular symmetry appear simultaneously. LÄS MER

  2. 2. Studies on the structure and biogenesis of membrane proteins from the green alga Chlamydomonas reinhardtii

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Ghasem Nurani; Stockholms universitet.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi;

    Sammanfattning : The green alga unicellular Chlamydomonas reinhardtii has been used for many years as a model system in the area of photosynthesis. Therefore, the C. reinhardtii chloroplast has been the subject of many studies. In contrast, the mitochondria have received less attention. LÄS MER

  3. 3. Reconstruction of Past European Land Cover Based on Fossil Pollen Data : Gaussian Markov Random Field Models for Compositional Data

    Detta är en avhandling från Lund University, Faculty of Science, Centre for Mathematical Sciences, Centre for Environmental and Climate Research

    Författare :Behnaz Pirzamanbein; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016-11]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spatial Statistics; Adaptive Markov Chain Monte Carlo; Dirichlet Observation; Confidence Region; Palaeoecology; Past Human Land Use; Stochastic Partial Differential Equation;

    Sammanfattning : The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. LÄS MER

  4. 4. Aircraft Systems Conceptual Design An object-oriented approach from <element> to <aircraft>

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ingo Staack; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.

  5. 5. Protease Activity, Inhibition and Ligand Interaction Analysis Developments and Applications for Drug Discovery

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Thomas Gossas; Uppsala universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; proteases; kinetics; biosensors; inhibition; calcium; drug discovery; Biokemi;

    Sammanfattning : The present study has focused on characterising protease-ligand interactions in the context of drug discovery. The proteases that have been studied are human matrix metallopeptidase 12 (MMP-12), HIV-protease and Hepatitis C virus (HCV) NS3/NS4A protease. LÄS MER
