  1. 1. Resource Allocation under Uncertainty : Applications in Mobile Communications

    Författare :Mathias Johansson; Anders Ahlén; Mikael Sternad; Vikram Krishnamurthy; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; resource allocation; uncertainty; probability theory as logic; scheduling; multiuser diversity; Jaynes; maximum entropy; Bayesian probability theory; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Sammanfattning : This thesis is concerned with scheduling the use of resources, or allocating resources, so as to meet future demands for the entities produced by the resources. We consider applications in mobile communications such as scheduling users' transmissions so that the amount of transmitted information is maximized, and scenarios in the manufacturing industry where the task is to distribute work among production units so as to minimize the number of missed orders.

  3. 2. Extended Jaynes-Cummings Models In Cavity Qed

    Författare :Jonas Larson; Stig Stenholm; Peter L. Knight; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Optics; Optics; Optik;

    Sammanfattning : Due to the improvement within cavity quantum electrodynamics experiments during the last decades, what was former seen as 'toy models' are today realized in laboratories. A controlled isolated coherent evolution of one or a few atoms coupled to a single mode inside a cavity is achievable. LÄS MER

  4. 3. Time dependent processes incavity QED

    Författare :Jonas Larson; KTH; []
    Nyckelord :cavity QED; state preparation; non-classical; Jaynes-Cummings model; Fock state; measurement;

    Sammanfattning : Cavity quantum electrodynamics (QED) has become one of themost successful tools for quantum information processing, butalso for the study of other pure quantum effects. In thisthesis we investigate one such system, the micromaser; an atomtraverse a cavity and interacts with the quantized modes of thecavity field. LÄS MER

  5. 4. Ensembles and Open Quantum Systems in Polaritonic Chemistry

    Författare :Eric Davidsson; Markus Kowalewski; Gerrit Groenhof; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polaritonic Chemistry; Open Quantum Systems; Cavity QED; The Jaynes-Cummings Model; Optical Cavities; Computational Quantum Dynamics; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Optical cavities are structures where excitations in the electromagnetic field (photons of light) are confined and generally long-lived. The spatial confinement will enhance interactions with any matter systems in the cavity, such that the behaviour of a combined system is best understood in terms of polaritonic states; mixtures of excitations in both light and matter.

  7. 5. Understanding the application of knowledge management to the safety critical facilities

    Författare :Elena Ilina; Håkan Sundquist; Yanko Yanev; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear physics; Kärnfysik; Building engineering; Byggnadsteknik;

    Sammanfattning : Challenges to the operating nuclear power plants and transport infrastructures are outlined. It is concluded that most aggravating factors are related to knowledge. Thus, of necessity, effective knowledge management is required. LÄS MER
