  1. 1. The combination of SFDI with a mathematical model links perturbation in microcirculation to early stages of sepsis

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Caroline Korsfeldt; Sara Karajica; [2022]
    Nyckelord :SFDI; SFDS; mathematical modeling; sepsis;

    Sammanfattning : The microcirculation system is crucial for the function of delivering biological markers such as oxygen and removing carbon dioxide from all the cells forming the complex ma- trix of tissue in the body. To keep up with the demands of each and every cell, there is a response from the microvasculature - resulting from for instance changes in blood flow to the tissue area. LÄS MER

  3. 2. Indoor VLC behaviour  with RGB spectral power distribution using simulation.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Siva Babu Ajjapu; Sasank Reddy Lokireddy; [2021]
    Nyckelord :;

    Sammanfattning : n recent years visible light communication (VLC) has been one of the technologies overgrowing in this competitive world and breaking through the wireless transmission of future mobile communications. This VLC replaces radio frequency (RF), which has several important features like large bandwidth, low cost, unlicensed spectrum. LÄS MER

  4. 3. Ljudmodulering och Visuell Representation av Musik

    L3-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Ville Kjellqvist; Felix Gustafsson; Erik Orrenius; Pontus Rahm; [2020]
    Nyckelord :Inbyggda System; RGB; Arduino; Scenteknik; Musik; DMX; Neopixel; Signalbehandling;

    Sammanfattning : The ambition of this project was to create, program and control a matrix of individually controllable LEDs. This was achieved by utilizing a variety of microcomputers, such as Arduino, and by forging the hardware required for signal processing. LÄS MER

  5. 4. Musikvisualisering med LED-kub

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Linnea Palmqvist; Hillevi Nilsson; [2020]
    Nyckelord :musikvisualisering; LED; RGB; WS2811; Arduino;

    Sammanfattning : En 4x4x4 kub konstrueras av RGB LED's med integrerad drivrutin och via en Arduino styrs den av musiken som spelas. Arduinon får musiken som input och med hjälp av fouriertransform delas signalen upp i 128 logaritmiskt uppdelade bins. LÄS MER

  7. 5. Fabrication and characterisation of RGB LEDs based on nanowire technology

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Patrik Olausson; [2019]
    Nyckelord :RGB LEDs; InGaN; GaN; nitrides; platelets; nanotechnology; Technology and Engineering;

    Sammanfattning : The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. LÄS MER
