Sammanfattning :
In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. LÄS MER

Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik
Författare :Martin Christiansson; [2019]
Nyckelord :Technology and Engineering;
Sammanfattning :
In Reinforcement learning the updating of the value functions determines the information spreading across the state/state-action space which condenses the valuebased control policy. It is important to have an information propagation across the value domain in a manner that is effective. LÄS MER

Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap
Författare :Amandus Krantz; [2019]
Nyckelord :document image binarization; sample selection; neural networks; computer vision;
Sammanfattning :
The current state-of-the-art, in terms of performance, for solving document image binarization is training artificial neural networks on pre-labelled ground truth data. As such, it faces the same issues as other, more conventional, classification problems; requiring a large amount of training data. LÄS MER

Nyckelord :;
Sammanfattning :
In climate economics integrated assessment models (IAMs) are used to predict economic impacts resulting from climate change. These IAMs attempt to model complex interactions between human and geophysical systems to provide quantifications of economic impact, typically using the Social Cost of Carbon (SCC) which represents the economic cost of a one ton increase in carbon dioxide.
