  1. 6. Live VM Migration : Principles and Performance

    Författare :Petter Svärd; Erik Elmroth; Eric Jul; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Live Migration; Virtualization; business data processing; administrativ databehandling;

    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

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

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

  5. 9. Ultrasonic measurement principles : modeling, identification, and parameter estimation

    Författare :Jesper Martinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis presents contributions within the fields of ultrasonic modeling and measurement technology, with focus on solutions to difficult modeling and measurement problems. The work is divided into two categories: 1) processing of measurements obtained under non-ideal conditions, such as unsynchronized, distorted, and superimposed signals; 2) estimating acoustic models and parameters from materials, fluids, fluid mixtures, and thin-layered structures.

  7. 10. Total internal reflection ellipsometry : principles and applications

    Författare :Michal Poksinski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Spectroscopic ellipsometry has been used under conditions of total internal reflection to form a new measurement technique called Total Internal Reflection Ellipsometry. When measurement settings are appropriate for surface plasmon resonance to occur it is possible to combine the advantages of both ellipsometry and surface plasmon resonance and obtain very high sensitivity and precision.
