    Sammanfattning : This thesis treats the intersection between two of the largest transformations we are seeing within our society today; the cloud and the Internet-of-Things (IoT). The aim of this thesis is to investigate different ways to model and control a network of cloud services so that timing-critical IoT applications can make use of them. LÄS MER

  2. 2. Energy-efficient resource provisioning for cloud data centers

    Detta är en avhandling från Umeå : Department of Computing Science, Umeå University

    Författare :Selome Kostentinos Tesfatsion; Umeå universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Energy efficiency has become a fundamental concern in data centers, raising issues to all energy-related costs, including capital costs, operating expenses, and environmental impact. Energy inefficiency is mainly caused by unoptimized use of energy by sub-components of these data centers. LÄS MER

  3. 3. Analysing, modelling and controlling power-performance tradeoffs in data center infrastructures

    Detta är en avhandling från Umeå : Umeå University

    Författare :Jakub Krzywda; Umeå universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of this thesis is to analyse the power-performance tradeoffs in datacenter servers, create models that capture these tradeoffs, and propose controllers to optimise the use of data center infrastructures taking the tradeoffs into consideration. The main research problem that we investigate in this thesis is how to increase the power efficiency of data center servers taking into account the power-performance tradeoffs. LÄS MER

  4. 4. May the power be with you managing power-performance tradeoffs in cloud data centers

    Detta är en avhandling från Umeå University

    Författare :Jakub Krzywda; Umeå universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; data centers; power efficiency; power budgeting; application performance;

    Sammanfattning : The overall goal of the work presented in this thesis was to find ways of managing power-performance tradeoffs in cloud data centers. To this end, the relationships between the power consumption of data center servers and the performance of applications hosted in data centers are analyzed, models that capture these relationships are developed, and controllers to optimize the use of data center infrastructures are proposed.

  5. 5. Hydraulic transport of mineral and ore products friction losses of stratified flows at high solids concentrations

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Åsa Sundqvist; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The overall objective of the work presented in this thesis was to investigate the hydraulic transport of mineral and ore products with regard to friction losses in horizontal pipelines at high solids concentrations. In detail, the objectives are to present and examine experimental pilotscale and large-scale friction loss results, and to investigate the performance of a scaling relationship for stratified slurry flows with regard to the effects of pipe diameter and solids concentration.
