  1. 1. 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

  2. 2. Faktorer som påverkar patientens följsamhet tillkompressionsbehandling av venösa bensår – Enlitteraturöversikt

    Kandidat-uppsats, Högskolan Dalarna/Omvårdnad; Högskolan Dalarna/Omvårdnad

    Författare :Madeleine Andersson; Catrine Forslund; [2019]
    Nyckelord :Adherence; compression treatment; factors; patient; venous leg ulcers; Faktorer; följsamhet; kompressionsbehandling; patient; venösa bensår;

    Sammanfattning : Bakgrund: Förekomsten av venösa bensår hos den vuxna befolkningen i EU-länderna uppskattas vara mellan 490 000 upp till 1,3 miljoner personer. Den viktigaste behandlingen för att förebygga recidiverande bensår är kompressionsstrumpor. LÄS MER

  3. 3. Robust header compression for cellular IoT

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Måns Ansgariusson; Axel Wihlborg-Rasmusen; [2019]
    Nyckelord :RoHC; Robust Header Compression; IoT; Cellular IoT; Technology and Engineering;

    Sammanfattning : In this Master Thesis we aim to evaluate the Robust Header Compression protocol in cel- lular IoT. The initial results show that RoHC may decrease the energy consumption signif- icantly due to its reduction of the header size. The reduction in the header size decreases the required transmission window which in turn decreases the energy consumption. LÄS MER

  4. 4. Mastering Engineers, Loudness and Hyper-Compression : A survey about practises, application goals and ideas about how they impact quality

    Kandidat-uppsats, Luleå tekniska universitet/Medier ljudteknik och upplevelseproduktion och teater

    Författare :Emil Aspegren; [2018]
    Nyckelord :;

    Sammanfattning : The loudness wars have been a frequently debated topic in the audio industry. Earlier research has been done on the technical and perceptual effects of loudness and so called hyper- compression but little research has been done to investigate the opinions of the mastering engineers, those who are applying the processing.

  5. 5. Physical modeling of a heavy-duty engine for test-cycle simulations in Modelica

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Peter Jonsson; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Engine development for reduced fuel consumption and for the ability to use alternative types of fuels is required as emissions and the limited access of petroleum are issues coupled to diesel engines. Experimental testing is in many cases insufficient and expensive in comparison with simulations for engine development. LÄS MER
