Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: By establishing the nonlinear vibration model of a resonant accelerometer, this article analyzes the effects of mechanical nonlinearity and electrostatic nonlinearity on the output frequency ...

Abstract: The photodiode (PD) model in the recently reported works is based on a specified bias condition, which can not fully characterize the state of PD under large signal excitation. A large ...
