  1. 11. Analysis and Design of Rateless Codes

    Författare :Iqbal Hussain; Lars Kildehøj Rasmussen; Petar Popovski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The invention of turbo codes and the re-discovery of sparse graph codes constitute a milestone in error-correction codes designed for communication and storage systems. Sparse graph codes such as low-density parity-check codes can offer a performance that approaches the previously elusive Shannon capacity with reasonable practical computational complexity. LÄS MER

  3. 12. Biological data exchange and the discovery of new protein families in metagenomic samples

    Författare :David N. Messina; Erik Sonnhammer; Miguel Andrade; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Sammanfattning : The rise in sequence data has brought both challenges to the way we exchange biological information and opportunities to discover new protein families, primarily through the investigation of uncultured metagenomic samples.The Distributed Annotation System, or DAS, provided a means for exchanging protein sequence data, but there were no open source, stand-alone DAS clients optimized for integrating and viewing these data.

  4. 13. Cooperative Communication for Increased Reliability in Industrial Wireless Networks

    Författare :Svetlana Girs; Mats Björkman; Lucia Lo Bello; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Introducing wireless networks into distributed industrial systems may enable new or improved application areas and also great cost reductions due to lower complexity of installation and maintenance, compared to existing wired solutions. However, signals travelling through wireless channels are affected by pathloss, fading and shadowing, and, as a result, packet errors are both time-varying and more frequent than in e. LÄS MER
