1. 31. Modeling and OpenFOAM simulation of streamers in transformer oil

   Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

   Författare :Jonathan Fors; [2012]
   Nyckelord :Computational Physics; High voltage; OpenFOAM; Streamer; Electric insulation; Electrodynamics; Finite Volume Method; Beräkningsfysik; Högspänningsteknik; OpenFOAM; Streamer; Elektrisk isolation; Elektrodynamik; Finita volymsmetoden;

   Sammanfattning : Electric breakdown in power transformers is preceded by pre-breakdown events such as streamers. The understanding of these phenomena is important in order to optimize liquid insulation systems. Earlier works have derived a model that describes streamers in transformer oil and utilized a finite element method to produce numerical solutions. LÄS MER

3. 32. Communication between hearing aids and external devices

   Magister-uppsats, Lunds universitet/Logopedi, foniatri och audiologi

   Författare :Marianne Philipsson; [2008]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : New technology makes it possible for existing hearing aids to communicate with each other to make a true binaural fitting and give all of the experiences and advantages of binaural hearing to the user. This project includes electro-acoustic measurements done on one system available on the market. LÄS MER
