3. 22. Exploring Normalizing Flow Modifications for Improved Model Expressivity

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Marcel Juschak; [2023]
   Nyckelord :Normalizing Flows; Motion Synthesis; Invertible Neural Networks; Glow; MoGlow; Maximum Likelihood Estimation; Generative models; normaliserande flöden; rörelsesyntes; inverterbara neurala nätverk; Glow; MoGlow; maximum likelihood-skattning generativa modeller;

   Sammanfattning : Normalizing flows represent a class of generative models that exhibit a number of attractive properties, but do not always achieve state-of-the-art performance when it comes to perceived naturalness of generated samples. To improve the quality of generated samples, this thesis examines methods to enhance the expressivity of discrete-time normalizing flow models and thus their ability to capture different aspects of the data.

4. 23. Multi-scale Bark Beetle Predictions Using Machine Learning

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

   Författare :Albert Øhrman Wellendorf; [2023]
   Nyckelord :Geography; GIS; Geographically weighted regression; bark beetle; machine learning; Earth and Environmental Sciences;

   Sammanfattning : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. LÄS MER

5. 24. System impact of micro-production

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Annie Haraldsson; [2023]
   Nyckelord :Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

   Sammanfattning : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. LÄS MER

7. 25. Calculating Value-at-Risk under the G-Normal distribution. : Applied with Swedish data.

   Kandidat-uppsats, Uppsala universitet/Nationalekonomiska institutionen

   Författare :Daniel Renvall Moberg; [2023]
   Nyckelord :;

   Sammanfattning : Value–at–Risk (VaR) since its birth at JPMorgan in the 1990s, has become widely adopted by first and foremost the financial industry, but in later days regulatory authorities as a way of calculating downside risk. The subject in hand has led to numerous attempts by both the industry as well as scholars to find the perfect settings to calculate VaR. LÄS MER
