   Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

   Abstract : Degradation of properties of semiconductor devices when layers of different materials are grown on top of each other is a common issue if their lattices are mismatched. Strain between them is reduced by creating defects like vacancies. This problem can be solved by growing structures, called nanowires, where stress is reduced radially. READ MORE
