  3. 2. Långsiktig torvnedbrytning för olika vegetationstyper på dikad skogsmark

    University essay from SLU/School for Forest Management

    Author : Carl Carlsson; Sofie Jönsson; [2023]
    Keywords : växthusgaser; torvmark; dikning;

    Abstract : Skogsklädda torvmarker i Sverige dikades i stor utsträckning mellan 1930- och 1980-talen i syfte att höja virkesproduktionen. Till följd av klimatproblemet har intresset för dikade torvmarkers bidrag till växthusgasutsläppen ökat under de senaste decennierna. READ MORE

  5. 4. Sublimation temperature prediction of OLED materials : using machine learning

    University essay from Uppsala universitet/Analys och partiella differentialekvationer

    Author : Niklas Norinder; [2023]
    Keywords : Semiconductors; OLED; machine learning; vapor deposition; sublimation; molecular property prediction; regression; ensemble learning; deep learning;

    Abstract : Organic light-emitting diodes (OLED) are and have been the future of display technology for a minute. Looking back, display technology has moved from cathode-ray tube displays (CRTs) to liquid crystal displays (LCDs). Whereas CRT displays were clunky and had quite high powerconsumption, LCDs were thinner, lighter and consumed less energy. READ MORE
