1. 16. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Robert Pim; [2023]
   Keywords : tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

   Abstract : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. READ MORE

3. 17. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

   University essay from Uppsala universitet/Elektricitetslära

   Author : Karolina Engström; Rebecca Waldenfjord; [2023]
   Keywords : Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

   Abstract : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). READ MORE

   Abstract : One of the key responsibilities of Getinge's ventilators is to deliver accurate gas volumes to patients. To ensure this precision, specially designed rigid steel tanks are utilized to evaluate the performance and precision of the ventilators in providing exact air volume. READ MORE

5. 19. The Revolution of Skill Acquisition in Sports: Comparing Linear and Non-Linear Pedagogical Methods to Teach Adolescents the Wide Receiver Stance and Start in American Football

   University essay from Lunds universitet/Institutionen för psykologi

   Author : Frederik Nielsen; [2023]
   Keywords : non-linear pedagogy; ecological dynamics; differential learning; deliberate practice; traditional learning; American football; Adolescents; Social Sciences;

   Abstract : In the last decade, the philosophy behind deliberate practice and traditional learning methods have received criticism for the limitations as a learning method. The purpose of this study was to compare the effects of linear and non-linear pedagogical methods for teaching the wide receiver stance and start to adolescents. READ MORE

6. 20. Line Distance Protection in Power Grids with Variable Renewable Energy Sources : An Investigation on Time Domain Distance Protection via Parameter Estimation

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