  1. 1. On Bicompositional Correlation

    Author : Jakob Bergman; Lund University.; Lunds universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Joint correlation coefficient; Empirical confidence coefficient; Dirichlet distribution; Correlation; Composition; Compositional data; Random variate generation; Simplex;

    Abstract : 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. READ MORE

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

    University dissertation from Linköping : Linköping University Electronic Press

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

    Abstract : 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. READ MORE

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

    University dissertation from Department of Geology, Lund University

    Author : Niklas Axheimer; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Paleontologi; Palaeontology; fysisk geografi; Geologi; physical geography; Geology; Sweden; correlation; trilobites; biostratigraphy; Cambrian; Sedimentology;

    Abstract : 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. READ MORE

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

    University dissertation from Department of Geology, Lund University

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

    Abstract : 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

    University dissertation from Department of Information Technology, Lund Univeristy

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

    Abstract : 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. READ MORE
