  1. 1. P2P Live Video Streaming

    Författare :Ilias Chatzidrossos; Gunnar Karlsson; Marco Mellia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; p2p systems; live streaming; mesh-based systems; Telecommunication; Telekommunikation;

    Sammanfattning : The ever increasing demand for video content directed the focus of researchfrom traditional server-based schemes to peer-to-peer systems for videodelivery. In such systems, video data is delivered to the users by utilizing theresources of the users themselves, leading to a potentially scalable solution. LÄS MER

  3. 2. Distributed Optimization of P2P Media Delivery Overlays

    Författare :Amir H. Payberah; Seif Haridi; Alberto Montresor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; P2P overlay networks; P2P live streaming; Distributed optimization; Electronics; Elektronik; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Media streaming over the Internet is becoming increasingly popular. Currently, most media is delivered using global content-delivery networks, providing a scalable and robust client-server model. However, content delivery infrastructures are expensive. LÄS MER

  4. 3. Live Streaming Performance of Peer-to-Peer Systems

    Författare :Ilias Chatzidrossos; György Dán; Renato Lo Cigno; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In peer-to-peer (P2P) live streaming systems peers organize themselves in an overlay and contributewith their resources to help diffuse live content to all peers in a timely manner. The performanceof such systems is usually characterized by the delay-loss curve, which quantifies theplayback delay required for achieving a certain streaming quality, expressed as the chunk missingratio at the peers.

  5. 4. Fluid Flow and Heat Transfer Simulations for Complex Industrial Applications : From Reynolds Averaged Navier-Stokes towards Smoothed Particle Hydrodynamics

    Författare :Md Lokman Hosain; Rebei Bel Fdhila; Konstantinos Kyprianidis; Erik Dahlquist; Hailong Li; Moncho Gomez Gesteira; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics; Heat transfer; Industrial applications; Reynolds Averaged Navier-Stokes; Smoothed Particle Hydrodynamics; Energy enginnering; Thermal Management; Process control; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Optimal process control can significantly enhance energy efficiency of heating and cooling processes in many industries. Process control systems typically rely on measurements and so called grey or black box models that are based mainly on empirical correlations, in which the transient characteristics and their influence on the control parameters are often ignored.
