   Keywords : Artificial Neural Networks; ANN; Deep learning; Quantum physics; Inverse problem; Inverse; Machine learning; Density functional theory; DFT; Physics; Computational physics; Technology and Engineering;

   Abstract : Inverse problems are important in quantum physics as their solutions are essential in order to describe a number of systems using measurable information, e.g. excitation energies or material properties. The problem with inverse problems is that they are usually very hard to solve. READ MORE

6. 20. Thermal modeling of power electronic components in excitation systems

   University essay from

   Author : Fredrik Widberg; [2019]
   Keywords : Excitation systems; Power electronics; Thermal modeling;

   Abstract : This thesis work aims at developing a model in Visual Basic for Applications and Microsoft Excel that can be used to predict temperatures in semiconductor devices for two commercial products made by Voith Hydro AB, and via simulation of the model determine the maximum current that can be conducted through the two products. The two products are called field exciters. READ MORE
