  3. 3. Live VM Migration Principles and Performance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Petter Svärd; Umeå universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Live Migration; Virtualization; administrativ databehandling; Computing Science;

    Sammanfattning : Virtualization is a key technology for cloud computing as it allows several operating system instances to run on the same machine, enhances resource manageability and enables flexible definition of billing units. Virtualization works by adding a software layer, a hypervisor, on top of the hardware platform. LÄS MER

  5. 5. Polar molecules in crystalline and surface environments : From first principles

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Alfredsson; Uppsala universitet.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : With the knowledge of the composition and structure of a chemical system, be it a molecule, a two-dimensional surface or a three-dimensional crystal, it is now possible to predict the specific properties of the compound under consideration via computational studies. Molecular and periodic Hartree-Fock and DFT calculations have been used as a tool to study polar molecules and how their properties respond to the molecular environment in a crystal or on an ionic surface.
