1. 1. Quality enhancement of time-resolved computed tomography scans with cycleGAN

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Johannes Stubbe; [2023]
   Nyckelord :carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

   Sammanfattning : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. LÄS MER

3. 2. Wildfire growth modelling in Sweden - a suitability assessment of available data

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Henrik Hagelin; [2023]
   Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

   Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

4. 3. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Tómas Halldórsson Alexander; [2023]
   Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

   Sammanfattning : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

5. 4. Evaluating the impact of agriculture on albedo using Sentinel-2 data in southern Sweden

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Victor Andréasson; [2023]
   Nyckelord :Physical geography and ecosystem science; Remote sensing; Sentinel-2; Albedo; Agriculture; Earth and Environmental Sciences;

   Sammanfattning : The climate impact of food production plays a big part in the anthropogenic climate impact. Mitigation strategies from this sector are hence of great importance. One area which mainly has been used to calculate climate impact is albedo, the overall reflectance of incoming radiation in all directions. LÄS MER

7. 5. Toward Equine Gait Analysis : Semantic Segmentation and 3D Reconstruction

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Evelina Hult; [2023]
   Nyckelord :Deep Learning; Computer Vision; Semantic Segmentation; Structure-from-Motion; Equine Gait Analysis; Harness Racing Horses; Engineering and Technology; Natural Sciences; Computer Vision Laboratory;

   Sammanfattning : Harness racing horses are exposed to high workload and consequently, they are at risk of joint injuries and lameness. In recent years, the interest in applications to improve animal welfare has increased and there is a demand for objective assessment methods that can enable early and robust diagnosis of injuries.
