1. 1. 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. 2. Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Emmanouil Papadakis; [2023]
   Keywords : Geography; GIS; Satellite Remote Sensing; Vegetation Indices; Classification; Archaeology; Earth and Environmental Sciences;

   Abstract : During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception of archaeological landscapes and predict past behaviors.

4. 3. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

   University essay from Lunds universitet/Matematisk statistik

   Author : Mika Persson; [2022]
   Keywords : Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

   Abstract : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

5. 4. Quantifying Middle Frequency Transient Currents in Power Consuming Devices

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Alex Lundvall; Vincent Sollie; [2021]
   Keywords : ;

   Abstract : The complexity of electrical systems present in vehicles is continuously rising and the number of interconnected electrical devices is growing during the strive for optimization and reaching higher efficiency levels. Actuation of said devices have the possibility of injecting voltage and current harmonics into the system, thus negatively affecting neighbouring devices. READ MORE

6. 5. Time series analysis for spring barley phenology monitoring using Sentinel 2 – A case study of Southern-central Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Pavlos Aslanis; [2020]
   Keywords : spring barley; crop phenology; crop growth stages; TIMESAT; double logistic; threshold optimization; Sentinel 2; Earth and Environmental Sciences;

   Abstract : Monitoring crop phenology at parcel scale aligns with the concept of precision agriculture (PA) and can provide invaluable information to agronomic management systems. Satellite time series data are commonly deployed for detecting crop growth stages, while the recent advancements in remote sensing (RS) technologies such as the launch of Sentinel 2 (S2) are providing unprecedented opportunities for crop monitoring.
