  1. 1. The Impact of Deep Neural Network Pruning on the Hyperparameter Performance Space: An Empirical Study

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Jonna Matthiesen; [2023-10-24]
    Nyckelord :Compression; Deep Learning; DNN; Hyperparameters; Optimization; Pruning; Hyperparameter Optimisation; Hyperparameter Tuning;

    Sammanfattning : With the continued growth of deep learning models in terms of size and computational requirements, the need for efficient models for deployment on resource-constrained devices becomes crucial. Structured pruning has emerged as a proven method to speed up models and reduce computational requirements. LÄS MER

  3. 2. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    Master-uppsats,

    Författare :Delshad Mansour Ayoubi; [2022-12-06]
    Nyckelord :Medical physics; Activity concentration; Transfer coefficient; Dose;

    Sammanfattning : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. LÄS MER

  4. 3. Minskande senvuxenhet på produktiv skogsmark i Norrland : implikationer för vedlevande organismer och betydelsen av myr- och bergimpediment

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Tyr Nilsson; [2022]
    Nyckelord :Slow-grown trees; growth rate; ring width; pinus sylvestris; picea abies; low-productive forests; mires; rocky outcrops; swedish NFI;

    Sammanfattning : Senvuxen ved är ett viktigt substrat för vissa vedlevande organismer på grund av en långsam nedbrytning och låg konkurrens. Tillväxtförhöjande åtgärder inom skogsbruk, liksom ökande temperaturer, kan ha orsakat en minskning av senvuxen ved under den senare halvan av 1900-talet. LÄS MER

  5. 4. Prolongation of shelf life of minimally processed spinach by combining vacuum impregnation and electric field treatments

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sophia Leffler; [2022]
    Nyckelord :spinach; pulsed electric field; moderate electric field; reversible electroporation; vacuum impregnation; shelf life; metabolic activity; respiration; food engineering; Agriculture and Food Sciences;

    Sammanfattning : A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. LÄS MER

  7. 5. Spruce associated Porodaedalea species distribution in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Monica Guilera Recoder; [2022]
    Nyckelord :Fungi; Genetics; Porodaedalea;

    Sammanfattning : Wood-inhabiting fungi have very important roles in the ecosystem in the degradation of dead wood by acting respectively as parasites and saprotrophs in boreal forests. Porodaedalea chrysoloma is a wood-decay parasite poroid fungi that is considered a key species in the old growth boreal forests. Due to forestry its habitat is declining. LÄS MER
