  1. 1. Texture Analysis and Ultra high-frequency ultrasound in use for diagnosing Hirschsprung's disease

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Sophia Klarén; Jonathan Jedhammar; [2023]
    Nyckelord :Hirschsprung s disease; Aganglionosis; UHF ultrasound; Texture analysis; Nakagami; Skewness; Kurtosis; Technology and Engineering;

    Sammanfattning : An investigation into the use of statistical texture analysis in combination with ultra high-frequency ultrasound for diagnosing Hirschsprung’s disease (HD); An illness that manifests itself through the absence of ganglia cells in lower parts of the intestine. Current diagnostic techniques carry a higher risk of long-term consequences in newborns and children which enables a new avenue of research into new methods. LÄS MER

  3. 2. Spectroscopic model characterisation of hot exoplanet atmospheres

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Elin Sandvik; [2022]
    Nyckelord :Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Sammanfattning : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. LÄS MER

  4. 3. Alternating Physically Based Renderingin Low-lit Areas

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Itamar Kupersmidt; [2018]
    Nyckelord :Physically based rendering; Roughness; Low-lit environments;

    Sammanfattning : Background The increase in screen resolution has increased from HD to Ultra-HDduring the last decade. A modern game today with Ultra-HD resolution has overeight million pixels that need to be shaded, combined with the expensive shadingmethod Physically Based Rendering the equations needed to calculate each pixel arenumerous.

  5. 4. From Set Top Box to Home Media Center

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Författare :Yi Fu; Ruimin Li; [2014]
    Nyckelord :Multimedia; HMC; STB; Prototype; Roadmap; IPTV; Ultra HD; Multimedia; HMC; Digitalboxar; Prototyp; Färdplan; IPTV; Ultra HD;

    Sammanfattning : Although Set-top-Boxes(STBs) are widely deployed today to connect a media source to a display (traditionally a television set), the market is changing due to the introduction of Internet Protocol Television, Over-the-Top streaming devices, gaming console, home theater Personal Computer, smart TV, etc. There is an evolving concept of a Home Media Center (HMC).
