1. 1. Evaluation of the Weather Resistance of Ram-Air Kites Used in Airborne Wind Energy Systems

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Johanna Désirée Ambs; [2023]
   Keywords : Weathering Resistance; Coated Textiles; Ram-air Kite; Airborne Wind Energy;

   Abstract : Airborne Wind Energy is an emerging technology that harnesses the power of the wind by using tethered wings. Among the flying devices are ram-air wings made from coated textiles that utilize dynamic pressure to gain their shape. READ MORE

3. 2. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Hanna Damsgaard Falck; [2023]
   Keywords : Porous media; COMSOL Multiphysicis; Darcy s Law; Richard s Equation; Resin Impregnated Paper Bushings; RIP Bushings; Bushings; Transformers; Epoxy; Simulation;

   Abstract : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. READ MORE

4. 3. The effect of body position on the relative contribution of the rib cage to speech breathing and voice quality

   University essay from Stockholms universitet/Avdelningen för fonetik

   Author : Helena Engström; [2023]
   Keywords : Speech breathing; body position; voice quality; respiratory inductance plethysmography; accelerometer; Talandning; kroppsposition; röstkvalité; respiratory inductance plethysmography; accelerometer;

   Abstract : This study investigates how body position affects the relative contribution of the rib cage to speech breathing and voice quality. The frequently used upright and supine body positions are expanded with the addition of an inverted position as a condition. READ MORE

5. 4. Analysis of Resin Impregnated Non-woven : In collaboration with Hitachi Energy

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Ahmed Abdulkareem Najm Al-Saedi; Anders Hedenfeldt; Andrea García; Anna-Karin Kron; Cornelia Bergström; Lova Källkvist; [2022]
   Keywords : resin impregnated non-woven; bushings; composite; resin impregnated paper; tensile; bending; permeability; mechanical properties;

   Abstract : High voltage bushings are the most critical components of power transformers. A common material used in bushings is resin impregnated paper (RIP). Hitachi Energy is investigating whether this can be replaced with a new material, resin impregnated non-woven (RIN). READ MORE

6. 5. Epoxy filling simulation of an RIP bushing

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Nil Tabudlong Jonasson; Simon Palm; [2022]
   Keywords : COMSOL; Porous Media Flow; RIP Bushing; Electrical Bushing; Filling Simulation;

   Abstract : The manufacturing process for the core of an RIP bushing was studied. Simulations of a test model was performed, due to the non-linear nature of the fluid filling process. Varying of governing parameters in the model, that could realistically be varied, was carried out and their affect was observed. READ MORE
