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

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Caroline Korsfeldt; Sara Karajica; [2022]
    Keywords : SFDI; SFDS; mathematical modeling; sepsis;

    Abstract : 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. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Siva Babu Ajjapu; Sasank Reddy Lokireddy; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Fabrication and characterisation of RGB LEDs based on nanowire technology

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  5. 4. Improving green LEDs: A meta study into the causes and remedies of the green gap

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Andreas Malmgren; [2015]
    Keywords : Light emitting diodes; quantum wells; recombination rate; Technology and Engineering; Physics and Astronomy;

    Abstract : This literature review investigates and evaluates different strategies to improve InGaN-based light emitting diodes (LED) by analyzing published theoretical and experimental studies. The issues of non-uniform carrier distribution, piezoelectric polarization fields and poor wave function overlap can be mitigated by the use of InGaN barriers and substrates as well as staircase designs for quantum wells (QW).
