  1. 1. On Bicompositional Correlation

    Författare :Jakob Bergman; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Joint correlation coefficient; Empirical confidence coefficient; Dirichlet distribution; Correlation; Composition; Compositional data; Random variate generation; Simplex;

    Sammanfattning : A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. LÄS MER

  2. 2. On Film Cooling of Turbine Guide Vanes From Experiments and CFD-Simulations to Correlation Development

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Hossein Nadali Najafabadi; Linköpings universitet.; Linköpings universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Film Cooling; Gas Turbine; Correlation; CFD; Cylindrical holes; Fan-shaped Holes;

    Sammanfattning : To achieve high thermal efficiency in modern gas turbines, the turbine-inlet temperature has to be increased. In response to such requisites and to prevent thermal failure of the components exposed to hot gas streams, the use of different cooling techniques, including film cooling, is essential. LÄS MER

  3. 3. Electronic transitions and correlation effects From pure elements to complex materials

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johan Jönsson; Igor A. Abrikosov; Marcus Ekholm; Sergei Dudarev; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic transition; solid state physics; condensed matter physics; correlation effects;

    Sammanfattning : Macroscopic properties of real materials, such as conductivity, magneticproperties, crystal structure parameters, etc. are closely related or evendetermined by the configuration of their electrons, characterized by electronicstructure. By changing the conditions, e.g, pressure, temperature, magnetic/electric field, chemical doping, etc. LÄS MER

  4. 4. The lower and middle Cambrian of Sweden: trilobites, biostratigraphy and intercontinental correlation

    Detta är en avhandling från Department of Geology, Lund University

    Författare :Niklas Axheimer; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Paleontologi; Palaeontology; fysisk geografi; Geologi; physical geography; Geology; Sweden; correlation; trilobites; biostratigraphy; Cambrian; Sedimentology;

    Sammanfattning : This thesis is based on studies of Cambrian successions in Sweden, with particular focus on the middle Cambrian biostratigraphy and its correlative relationship to the proposed global agnostoid zonation. The investigated material, mainly trilobites, was collected from both outcrops and drill cores from five provinces in Sweden: Skåne (Scania), Öland, Västergötland, Jämtland and Lapland. LÄS MER

  5. 5. The Aerodynamic Correlation of a Scale Model with a Full Size Car

    Detta är en avhandling från Department of Geology, Lund University

    Författare :Lasse Malmkjaer Christoffersen; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling flow.; Correlation; Experiment; Reynolds number; Road Vehicle Aerodynamics; CFD; Scale model;

    Sammanfattning : Reducing the Worlds consumption of energy has become an important part of the current political and environmental debate. The reasons are obvious: World population is increasing, continued growth in living standards, finite availability of resources and finally green house gas emissions from energy production have to be brought down to stabilize temperatures.
