  1. 1. On Bicompositional Correlation

    Författare :Jakob Bergman; Lunds universitet.; Lund University.; [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. 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; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Paleontologi; Palaeontology; fysisk geografi; Geologi; physical geography; Geology; Sweden; correlation; trilobites; biostratigraphy; Cambrian; Sedimentology;

    Sammanfattning : Popular Abstract in Swedish Kambrium är ett tidsavsnitt av jordens historia som spänner från ca 542 till 488 miljoner år sedan. Under denna tid utvecklades livet, främst djur, i en rasande takt genom något som brukar kallas den kambriska explosionen, en ekologisk förändring utan dess like. LÄS MER

  4. 4. 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.

  5. 5. Some results on fast correlation attacks

    Detta är en avhandling från Department of Information Technology, Lund Univeristy

    Författare :Fredrik Jönsson; Lunds universitet.; Lund University.; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; stream ciphers; linear feedback shift registers; cryptology; correlation attacks; cryptanalysis; Teknik; Informatics; systems theory; Informatik; systemteori;

    Sammanfattning : This thesis presents new results on fast correlation attacks on stream ciphers. In particular, fast correlation attacks on stream ciphers containing linear shift registers with an arbitrary number of taps, are considered. A general introduction to stream ciphers and correlation attacks is given. LÄS MER
