The focus of my current research is on polycrystalline materials. I have developed two-dimensional computer simulations based on Monte Carlo Potts model to investigate microstructural evolution of polycrystalline materials. The model is shown to be successful in simulating the degeneration of lamellar structures formed upon eutectoid phase transformations. In addition, the model is developed to study microstructural evolution in three-phase polycrystalline materials. Moreover, the model is adjusted to simulate grain size distributions in two-phase polycrystalline materials. The model is also developed to simulate grain growth in liquid-phase sintered materials. An important research work now is an investigation of the dependence of PV cell maximum output power (MPP) dependence on different parameters using MatLab simulation. My work also emphasizes the development of interactive computing approach based on data mining techniques to study one of the business fields to produce a busin
