Final paper research present and shared our extensive paper research result.
Strategy Modification
Asked professors for feedback and modify our strategy
Finished the diffusion simulation by finite differencing explicit methods in 2D
Tested the first data and found the suitable model by regression
Statistical test by the pair-difference T test
Designed electrical circuit to reduce the cost
Finished the statistical inference and the whole statistical inference and prediction
Strategy modification and asked for users’ feedbacks, we add more functions to strengthen our product integrity
Made app that suits our user-friendly experience
Built a system that upload the data to the cloud via Bluetooth and app
Cooperated with wet lab and test the flow of device
Tested all functions of our system
Final Feedback Searching
Demonstrated to our potential users ask for final feedbacks
