1. 21. Using forest reflectance modelling to estimate albedo for narrow-view satellites

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

   Author : Nick Bergmans; [2023]
   Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

   Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE

3. 22. Improving the experimental setup for ultrasound-optical tomography imaging

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ibtisam Dahir Ahmed; [2023]
   Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

   Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE
