    Författare :Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

    Sammanfattning : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. LÄS MER

  3. 2. Hybrid energy storage systems : Capacity optimization and environmental implication of hybrid energy storage systems in renewable power systems

    Författare :Yang Jiao; Daniel Månsson; Alfred Rufer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electricity production contributes a large share of greenhouse gas emissions that lead to climate change. At present, power generation in many parts of the world still heavily depends on fossil fuels. To prevent global warming, the electricity sector is supposed to transition from the current fuel mix to renewable energy sources. LÄS MER

  4. 3. Strategic Planning of Knowledge Management Systems : A Problem Exploration Approach

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap; Knowledge management; Informatics; computer and systems science; Information Systems;

    Sammanfattning : Knowledge management (KM) is focused on the problems and opportunities of using organizational knowledge as a resource. Information systems that are used to support KM processes are called knowledge management systems (KMS). LÄS MER

  5. 4. Resource Management in Computing Systems

    Författare :Payam Amani; Bredbandskommunikation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Resource management is an essential building block of any modern computer and communication network. In this thesis, the results of our research in the following two tracks are summarized in four papers. The first track includes three papers and covers modeling, prediction and control for multi-tier computing systems. LÄS MER

  7. 5. Energy Storage Systems in Electrical Distribution Grids : Analysis and implementations of use cases for service stacking
