1. 16. Evaluation of the variation in albedo over snow-covered forest in Northern Sweden and Finland

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Klara Hugosson; [2022-05-20]
   Keywords : ;

   Abstract : The effect of albedo variability induced by meteorological parameters in snow-covered forested areas at local scale is poorly known. Few meteorological stations measure albedo, even though the effect on albedo caused by land use changes is well known. READ MORE

3. 17. Video Retargeting using Vision Transformers : Utilizing deep learning for video aspect ratio change

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gil Laufer; [2022]
   Keywords : Video retargeting; Aspect ratio; Computer vision; Deep learning; Vision transformers.; Video retargeting; Bildförhållande; Datorseende; Djupinlärning; Vision transformers.;

   Abstract : The diversity of video material, where a video is shot and produced using a single aspect ratio, and the variety of devices that can play video with screens in different aspect ratios make video retargeting a relevant topic. The process of fitting a video filmed in one aspect ratio to a screen in another aspect ratio is called video retargeting, and the retargeted video should ideally preserve the important content and structure of the original video as well as be free of visual artifacts.

4. 18. Modeling the Head Effect in Hydropower River Systems using MILP and BLP Approaches

   University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Author : Lina Larsson; Mikaela Lindberg; [2022]
   Keywords : Hydropower optimization; Hydropower scheduling; The head effect; Bilinear programming; Mixed-integer linear programming;

   Abstract : With a fast-growing electricity demand and a larger proportion of intermittent energy sources follows a greater need for flexible and balancing sources of electricity, such as hydropower. Planning of hydropower production is considered to be a difficult problem to solve due to several nonlinearities, combinatorial properties and the fact that it is a large scale system with spatial-temporal coupling.

5. 19. Utilizing Genetic Algorithm and Machine Learning to Optimize a Control System in Generators : Using a PID controller to damp terminal voltage oscillations

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Fredrik Strand; [2022]
   Keywords : AVR; AI; data-driven; GA; SVM; GPR; SVR; Ziegler-Nichols; Z-N;

   Abstract : Hydropower is an important part of renewable power production in Sweden. The voltage stability of the already existing hydropower needs to be improved. One way to do this is by improving the control system that damp terminal voltage oscillations. READ MORE
