  1. 1. ISAR Imaging Enhancement Without High-Resolution Ground Truth

    University essay from Linköpings universitet/Datorseende

    Author : Moltas Enåkander; [2023]
    Keywords : SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

    Abstract : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. READ MORE

  3. 2. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Rebecka Ståhl; Parvathy Biju; [2023]
    Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

    Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

  4. 3. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Lukas Jönsson; [2023]
    Keywords : Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

    Abstract : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

  5. 4. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Erik Fridén; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE

  6. 5. Correlation between Normalized Difference Vegetation Index (NDVI) and in vitro organic matter digestibility (IVOMD) of reindeer pasture plants : Korrelation mellan Normalized Difference Vegetation Index (NDVI) och smältbarhet av renbetesväxter i vomvätska in vitro (VOS)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Jannica Helmersson; [2023]
    Keywords : Normalized Difference Vegetation Index; NDVI; in vitro organic matter digestibility; IVOMD; VOS; caribou; Rangifer tarandus; reindeer pasture plants; drone;

    Abstract : Renen livnär sig på många olika betesväxter och den följer växtfenologins utveckling under barmarkssäsongen, vilket resulterar i högkvalitativt foderintag. Levande växtbiomassa kan uppskattas på landskapsnivå genom att använda vegetationsindex som värderar vegetation utifrån spektrala mätningar. READ MORE
