Artificial neural network asst silicon crystal growth CZ method modeling :

• Cz method was implemented via COMSOL multiphysics commercial software.
• 900 data where collected by changing parameters (crystal spinning speed, crucible spinning speed, insolation thermal conductivity. milt hight).
• Artificial neural network was traind using the data to establish a relationship between the parameters and the crystal-melt interface.
• Bayesian regularization was using to solve overfitting problem.
• Levenberg-Masquardt algorithm was used for optimization.

• Optimizing a 3D design of a Dog robot for educational marketing purposes
• Performing quality control to produce cheap yet durable robots to sustain mechanical stresses
• Simplifying the robot structure to be fit for educational purposes
• Using Arduino to control the dog robot
