  1. 11. Adaptive content-based sound compression

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Markus Gerard; Marcus Tedenvall; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Three different classification solutions for distinguishing events from non-events in surveillance audio are described and evaluated. The three compared methods are energy functions, Gaussian mixture modelling algorithms (GMM) and existing voice activity detectors (VAD). LÄS MER

  3. 12. Implementation and Evaluation of Encoder Tools for Multi-Channel Audio

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Tomas Malmelöv; [2019]
    Nyckelord :Scene based audio; 3D audio; Spatial audio; Ambisonics; HOA; Multi-channel audio; Audio compression; MPEG-H;

    Sammanfattning : The increasing interest for immersive experiences in areas such as augmented and virtual reality makes high quality 3D sound more important than ever before. A technique for capturing and rendering 3D audio which has received more attention during the last twenty years are Higher Order Ambisonics (HOA). LÄS MER

  4. 13. Comparison of Video file transmission : over Dat protocol and Hypertext transfer protocol

    Kandidat-uppsats,

    Författare :Jonathan Artback; [2019]
    Nyckelord :P2P; Decentralized; Video; content;

    Sammanfattning : Context. Scalability and bittrate is an large concern when build-ing infrastructure and application for video content delivery. Manyresearch and companies have for a long time looked at peer to peertechnology as a way of solving the issue by utilizing the clients capac-ity.Objectives. LÄS MER

  5. 14. Cross-Layer Congestion Control with Deep Neural Network in Cellular Network

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Shimin Huang; [2019]
    Nyckelord :Congestion Control; Cellular Networks; Cross-Layer; Neural Networks; Trängselkontroll; Mobilnät; Tvärgående Lager; Neuronnät;

    Sammanfattning : A significant fraction of data traffic is transmitted via cellular networks. When introducing fifth-generation (5G) radio access technology, the maximum bitrate of the radio link increases significantly, and the delay is lowered. LÄS MER

  7. 15. Energy Consumption of Low Power Wide Area Network Node Devices in the Industrial, Scientific and Medical Band

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Rúni Eriksen; [2019]
    Nyckelord :LoRa; LoRaWAN; Sigfox; IoT; LPWAN; energy consumption; energy optimisation; LoRa; LoRaWAN; Sigfox; IoT; LPWAN; strömforbrukning; energioptimering;

    Sammanfattning : Low-Power Wide-Area Networks, LPWANs, achieve long communication ranges with a low energy consumption by communicating at low bit rates. Most LPWAN devices are battery powered and are required to operate for an extended period of time, which stresses the requirements for energy efficiency. LÄS MER
