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

    Författare :Tallat Mahmood Shafaat; Seif Haridi; Ali Ghodsi; Anwitaman Datta; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structured Overlay Networks; Distributed Hash Tables; DHTs; Network Partitions; Network Mergers; Network Size Estimation; Lookup Inconsistencies; Gossiping; Computer science; Datalogi;

    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

  3. 2. Distributed Estimation of Network Cardinalities

    Författare :Riccardo Lucchese; Luleå tekniska universitet; []
    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

  4. 3. Neural Network Architecture Design : Towards Low-complexity and Scalable Solutions

    Författare :Alireza M. Javid; Saikat Chatterejee; Alexandros Iosifidis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning :  Over the past few years, deep neural networks have been at the center of attention in machine learning literature thanks to the advances in computational capabilities of modern graphical processing units (GPUs). This progress has made it possible to train large scale neural networks by using thousands, and even millions, of training samples to achieve outstanding estimation accuracy in various applications that were not simply possible before.

  5. 4. Partition Tolerance and Data Consistency in Structured Overlay Networks

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

    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

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

    Författare :Martin Hartvig; Evolutionär ekologi; []
    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 : This thesis sets out a food web framework for size-structured populations. The framework enables an ecological approach to food web modelling as the individual life-history from birth, through maturation, and ultimately death is explicitly resolved with the use of bioenergetics based on individual body size.
