  1. 1. Bandwidth Efficient IPTV Distribution : On Error Resilience and Fast Channel Change

    Författare :Ulf Jennehag; Tingting Zhang; Stefan Pettersson; Nikolaus Färber; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IPTV distribution; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Television is now changing its traditional distribution forms to being distributed digitally over broadband networks. The recent development of broadband Internet connectivity has made the transition to Internet Protocol Television (IPTV) possible. LÄS MER

  3. 2. Fair Treatment of Multicast Sessions and Their Receivers : Incentives for more efficient bandwidth utilization

    Författare :Patrik Österberg; Tingting Zhang; Kirk Martinez; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bandwidth allocation; cost allocation; fairness; multicast; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Tjänster för strömmad media stiger kraftigt i popularitet, samtidigt som utbudet av denna typ av tjänster ökar. Internet protocol television (IPTV) med standardupplösning levereras redan till många hem, och högupplöst IPTV kommer att bli vanligt inom en relativt snar framtid. LÄS MER

  4. 3. On Spectrally Efficient Continuous Phase Modulation

    Författare :Tommy Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adjacent channel interference; additive white Gaussian noise {AWGN} ; convolutional codes; minimum Euclidean distance; continuous phase modulation CPM ; bandwidth efficiency; co-channel interference; reduced complexity detectors; optimized phase pulses.;

    Sammanfattning : Spectrally efficient partial response continuous phase modulation (CPM)for wireless links is considered. Continuous phase modulation defines constantenvelope phase codes, which are advantageous when using non-linear amplifiers. LÄS MER

  5. 4. Efficient training of interpretable, non-linear regression models

    Författare :Oskar Allerbo; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sparse regression; kernel regression; neural network regression; early stopping; bandwidth selection;

    Sammanfattning : Regression, the process of estimating functions from data, comes in many flavors. One of the most commonly used regression models is linear regression, which is computationally efficient and easy to interpret, but lacks in flexibility. LÄS MER

  7. 5. Efficient Memory Modeling During Simulation and Native Execution

    Författare :Nikos Nikoleris; Erik Hagersten; Lieven Eeckhout; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance analysis; cache performance; multicore performance; memory system; memory bandwidth; memory contention; performance prediction; multi-threading; multiprocessing systems; program diagnostics; commodity multicores; multithreaded program resource requirements; performance counters; scalability bottleneck; scalability improvement; Computer Science; Datavetenskap;

    Sammanfattning : Application performance on computer processors depends on a number of complex architectural and microarchitectural design decisions. Consequently, computer architects rely on performance modeling to improve future processors without building prototypes. LÄS MER
