Python

• Maze-Solving-Robot: A physical robot based on the control of Raspberry Pi was developed to design the maze solving algorithm and realize the solution of the maze in the real scene.
• Asteroids Predictor: A fast numerical simulator to predict the fate of asteroids entering Earth’s atmosphere, and use this simulator to develop a hazard mapper for an impact over the UK, then visualized it.
• Mineral Recovery Optimizer: A mineral recovery Optimizer using Genetic Algorithms, and generate a best circuit, then visualized it.
• Forecasting Induced Seismicity in Oklahoma: Several unique and rich datasets of candidate factors from regions in Oklahoma are used to statistically evaluate and retrospectively forecast possible signatures of human-induced seismicity from existing high-quality earthquake in these regions. These datasets contain geological formation, injections, hydraulic fracturing activities and wells, each of which have millions of items. This project originally designed and implemented a feedforward neural network model for induced seismicity forecasting, which effectively improves the performance of model fitting and prediction compared with logistic regression model also common-used in previous studies. The superiority of our neural network model was proven and their results about major factors to seismicity by two models were compared.
