1. 1. Self-Management for Large-Scale Distributed Systems

   Författare :Ahmad Al-Shishtawy; Vlassov Vlassov; Seif Haridi; Per Brand; Leandro Navarro Moldes; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Self-Management; Autonomic Computing; Control Theory; Distributed Systems; Grid Computing; Cloud Computing; Elastic Services; Key-Value Stores; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Autonomic computing aims at making computing systems self-managing by using autonomic managers in order to reduce obstacles caused by management complexity. This thesis presents results of research on self-management for large-scale distributed systems. LÄS MER

3. 2. Fundamental Limitations of Distributed Feedback Control in Large-Scale Networks

   Författare :Emma Tegling; Henrik Sandberg; Ali Jadbabaie; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed control; Large-scale systems; networked control; decentralized control; fundamental limitations; networked systems; frequency control; smart grid; consensus; spatial invariance; power system dynamics; microgrids; vehicular formation systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Networked systems accomplish global behaviors through local feedback interactions. The purpose of a distributed control design is to select interaction rules and control protocols that achieve desired global control objectives. LÄS MER

4. 3. On performance limitations of large-scale networks with distributed feedback control

   Författare :Emma Tegling; Henrik Sandberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. LÄS MER

5. 4. Distributed Peer Discovery in Large-Scale P2P Streaming Systems : Addressing Practical Problems of P2P Deployments on the Open Internet

   Författare :Raul Jimenez; Seif Haridi; Björn Knutsson; Arnaud Legout; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Peer-to-peer (P2P) techniques allow users with limited resources to distribute content to a potentially large audience by turning passive clients into peers. Peers can self-organize to distribute content to each other, increasing the scalability of the system and decreasing the publisher’s costs, compared to a publisher distributing the data himself using a content delivery network (CDN) or his own servers.

7. 5. Analysis of large-scale metagenomic data

   Författare :Fredrik Boulund; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; DNA analysis; big data; antibiotic resistance; hidden Markov models; high-performance computing; distributed computing; distributed computing;

   Sammanfattning : The topic of this thesis is the analysis of large data sets of DNA sequence data produced from modern high-throughput DNA sequencing machines. Using such machines to sequence the genetic content of a microbial community produces a metagenome. This thesis comprises three research papers, all connected to the study of large metagenomic data sets. LÄS MER
