  1. 1. Investigating the impact of physical layer transmission for Bluetooth LE Audio

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Kevin Arponen; Axel Björkman; [2023]
    Nyckelord :Bluetooth Low Energy; Energy consumption; LC3; LE Audio; Physical Layer; Throughput; Wireless audio streaming; Wireless communication;

    Sammanfattning : Bluetooth Low Energy (BLE) is a widely used low-energy version of Bluetooth’swireless protocol. To meet increasing requirements of modern wireless audio devices,Bluetooth LE Audio was released with its new Low Complexity CommunicationsCodec (LC3) being much more data efficient than its predecessor Low Complexity SubBand Coding.

  3. 2. Analysis and measurement of visuospatial complexity

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Alissar Al Saleh; [2023]
    Nyckelord :Computer Science; Artificial Intelligence; Visuospatial Complexity; Feature Congestion; Subband Entropy; Visual Clutter; Image annotation.;

    Sammanfattning : The thesis performs an analysis on visuospatial complexity of dynamic scenes, and morespecifically driving scenes in the propose of gaining a knowledge on human visual perception of the visual information present in a typical driving scene. The analysis and measurement of visual complexity is performed by utilizing two different measure modelsfor measuring visual clutter, Feature congestion clutter measure [1] and Subband entropyclutter measure[1] introduced by Rosenholtz, a cognitive science and research.

  4. 3. Analysis and Evaluation ofVisuospatial Complexity Models

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Bashar Hammami; Mjed Afram; [2022]
    Nyckelord :Complexity; Visual Complexity; Visuospatial Complexity; Strauctural Similarity Index Measurement; SSIM; Visual Clutter; Feature Congestion; Subband Entropy;

    Sammanfattning : Visuospatial complexity refers to the level of detail or intricacy present within a scene, takinginto account both spatial and visual properties of the dynamic scene or the place (e.g.moving images, everyday driving, video games and other immersive media). There havebeen several studies on measuring visual complexity from various viewpoints, e. LÄS MER

  5. 4. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects

    Master-uppsats, Lunds universitet/Matematisk fysik

    Författare :Josefin Reftlér; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. LÄS MER

  7. 5. Jämförelse av bluetooth codecs med fokus på batteriladdning, CPU användning och räckvidd

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Daniel Larsson; Kevin Ly Khuu; [2022]
    Nyckelord :Bluetooth codec; battery drainage; CPU usage; range; experiment; advanced audio coding; low-complexity subband codec;

    Sammanfattning : With the constant advances in technology, people are using more wireless products, such as earphones or speakers whereas many of them use Bluetooth. With the current advances in Bluetooth technology, consumers and manufacturers have a hard time keeping up with the pace. LÄS MER
