  1. 1. Towards CSCW design in the Scandinavian tradition

    University dissertation from Stockholm : Stockholm University

    Author : Konrad Tollmar; KTH.; KTH.; Stockholms universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SRA - ICT; SRA - Informations- och kommunikationsteknik; CSCW; Video communication; Media spaces; datalogi; Computer Science; Teams in the workplace; Data processing; Datorstött samarbete;

    Abstract : This thesis is about how to design Computer Supported Cooperative Work systems (CSCW) on the basis of design practice that is established in the Scandinavian model of System Design. The approach of the thesis is to develop an understanding of the design of CSCW environments through a series of case studies. READ MORE

  2. 2. Design and Implementation of Centrally-Coordinated Peer-to-Peer Live-streaming

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Roberto Roverso; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; live-streaming; nat traversal; TECHNOLOGY Electrical engineering; electronics and photonics Electrical engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektroteknik; TECHNOLOGY Information technology Computer engineering; TEKNIKVETENSKAP Informationsteknik Datorteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : In this thesis, we explore the use of a centrally-coordinated peer-to-peer overlay as a possible solution to the live streaming problem. Our contribution lies in showing that such approach is indeed feasible given that a number of key challenges are met. READ MORE

  3. 3. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fatemeh Rahimian; KTH.; SICS.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SRA - ICT; SRA - Informations- och kommunikationsteknik; Publish Subscribe; Content Distribution; Peer-To-Peer Overlay Network;

    Abstract : As the amount of data in todays Internet is growing larger, users are exposedto too much information, which becomes increasingly more difficult tocomprehend. Publish/subscribe systems leverage this problem by providingloosely-coupled communications between producers and consumers of data ina network. Data consumers, i.e. READ MORE

  4. 4. On the Performance Analysis of Large Scale, Dynamic, Distributed and Parallel Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : John Ardelius; KTH.; SICS.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SRA - ICT; SRA - Informations- och kommunikationsteknik; Performance analysis distributed systems;

    Abstract : Att utvärdera prestanda hos storskaliga distribuerade system är en viktigoch icke-trivial uppgift. I och med utvecklingen av Internet och det faktum attapplikationer och system har fått global utsträckning, har det uppkommit ettökande behov av kvantifiering av tillförlitlighet och prestanda hos dessa system.

  5. 5. Digital Dispersion Equalization and Carrier Phase Estimation in 112-Gbit/s Coherent Optical Fiber Transmission System

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Tianhua Xu; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherent transmission; chromatic dispersion; carrier phase estimation; digital signal processing; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik; TECHNOLOGY Electrical engineering; electronics and photonics Photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Fotonik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Coherent detection employing multilevel modulation format has become one of the most promising technologies for next generation high speed transmission system due to the high power and spectral efficiencies. With the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.
