  1. 1. Norsjömålet -En undersökning av invånares attityd till sin egen dialekt

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för humaniora, utbildnings- och samhällsvetenskap

    Författare :Freja Morén; [2020]
    Nyckelord :;

    Sammanfattning : That the dialects are gradually fading out is today a fact. There are many reasons why, but the fact that we are travelling more is of significant role together with the fast technical developments. LÄS MER

  3. 2. Evaluating user preference when applying mipmap LOD in shadow covered textures

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Jonas Berggren; [2020]
    Nyckelord :Textures; Mipmapping; Shadow Mapping; Level of Detail;

    Sammanfattning : Background. Shadow mapping is a method that is used for generating and imitating shadows in 3D-spaces. This technique has been used in the entertainment media industry in the form of games, movies and 3D renderings of environments to create a more realistic experience for consumers. LÄS MER

  4. 3. OTDOA-Based Positioning in Narrowband IoT

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

    Författare :Axel Berg; [2017]
    Nyckelord :IoT NB-IoT OTDOA Positioning; Technology and Engineering;

    Sammanfattning : This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. LÄS MER

  5. 4. Cell Acquisition and Synchronization for Unlicensed NB-IoT

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Eskil Jörgensen; [2017]
    Nyckelord :Narrowband Internet-of-Things; NB-IoT; unlicensed; cell search; cell acquisition; synchronization; artificial fast fading; binary sequences; peak sidelobe level;

    Sammanfattning : Narrowband Internet-of-Things (NB-IoT) is a new wireless technology designed to support cellular networks with wide coverage for a massive number of very cheap low power user devices. Studies have been initiated for deployment of NB-IoT in unlicensed frequency bands, some of which demand the use of a frequency-hopping scheme with a short channel dwell time. LÄS MER

  7. 5. Performance Analysis of a Cooperative Communication Network Over κ - μ Shadowed Fading for Different Relaying Protocols

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Alekhya Kodide; [2016]
    Nyckelord :Cooperative communications; κ−µ shadowed fading; relaying protocols; outage probability;

    Sammanfattning : With the fast development of today’s multimedia services, engineers face a huge hurdle that is, the overwhelming need of highly reliable communication over long distances. Cooperative communication is a novel concept which tackles this problem effectively. LÄS MER
