    Sammanfattning : Cloud Computing helps to efficiently utilize the abundance of computing resources in large data centers. It enables interested parties to deploy their services in data centers while the hardware infrastructure is maintained by the cloud provider. LÄS MER

  5. 24. May the power be with you : managing power-performance tradeoffs in cloud data centers

    Författare :Jakub Krzywda; Erik Elmroth; Per-Olov Östberg; Ahmed Ali-Eldin; Tarek F. Abdelzaher; Umeå universitet; []
    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.

  7. 25. Modelling the effects of organic aerosol phase partitioning processes on cloud formation

    Författare :Samuel Joseph Lowe; Ilona Riipinen; Daniel Partridge; Harri Kokkola; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cloud droplet activation; organic aerosol; cloud parcel modelling; Köhler theory; Sensitivity and Uncertainty analysis; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Atmospheric aerosols particles may act as cloud condensation nuclei (CCN) that provide sites for condensation of water vapour for the formation of cloud droplets, called cloud droplet activation. Whether aerosol particles are CCN is determined by their size, composition and the ambient humidity. LÄS MER
