  1. 1. Dealing with Network Partitions and Mergers in Structured Overlay Networks

    Detta är en avhandling från Stockholm : KTH

    Författare :Tallat Mahmood Shafaat; KTH.; SICS.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Structured Overlay Networks; Distributed Hash Tables; DHTs; Network Partitions; Network Mergers; Network Size Estimation; Lookup Inconsistencies; Gossiping;

    Sammanfattning : Structured overlay networks form a major classof peer-to-peer systems, which are touted for their abilitiesto scale, tolerate failures, and self-manage. Any long livedInternet-scale distributed system is destined to facenetwork partitions. LÄS MER

  2. 2. Distributed Estimation of Network Cardinalities

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Riccardo Lucchese; Luleå tekniska universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In distributed applications knowing the topological properties of the underlying communication network may lead to better performing algorithms. For instance, in distributed regression frameworks, knowing the number of active sensors allows to correctly weight prior information against evidence in the data. LÄS MER

  3. 3. Partition Tolerance and Data Consistency in Structured Overlay Networks

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Shafaat Tallat Mahmood; Tallat M. Shafaat; KTH.; Computer Systems Laboratory.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SRA - ICT; SRA - Informations- och kommunikationsteknik; Structured overlay networks; distributed Hash tables; network partitions and mergers; size estimation; lookup inconsistencies; distributed key-value stores; linearizability; dynamic reconfiguration; replication.;

    Sammanfattning : Structured overlay networks form a major class of peer-to-peer systems, which are used to build scalable, fault-tolerant and self-managing distributed applications. This thesis presents algorithms for structured overlay networks, on the routing and data level, in the presence of network and node dynamism. LÄS MER

  4. 4. Food Web Ecology -- individual life-histories and ecological processes shape complex communities

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Martin Hartvig; Lunds universitet.; Lund University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; food web; community ecology; community assembly; size-structure; life-history omnivory; ontogeny; trophic interactions; trait based model; topology; emergent organisation; size-spectrum;

    Sammanfattning : Popular Abstract in English A food web is a network diagram that describes which species that eat each other in nature. Such networks in marine environments e.g. show that cod eat herring, sprat, and sandeel - and that these eat numerous other species. LÄS MER

  5. 5. Seismicity Analyses Using Dense Network Data Catalogue Statistics and Possible Foreshocks Investigated Using Empirical and Synthetic Data

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Angeliki Adamaki; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistical Seismology; Earthquake Catalogue Statistics; Seismicity Patterns; Precursors; Foreshocks; Στατιστική Σεισμολογία; Κατάλογοι Σεισμών; Μοτίβα Σεισμικότητας; Πρόδρομα Φαινόμενα; Προσεισμοί; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Precursors related to seismicity patterns are probably the most promising phenomena for short-term earthquake forecasting, although it remains unclear if such forecasting is possible. Foreshock activity has often been recorded but its possible use as indicator of coming larger events is still debated due to the limited number of unambiguously observed foreshocks. LÄS MER
