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: This article uses computer-aided design tools to develop a describing function analysis of a pendulum clock. We design the escapement as a control system that allows the pendulum to provide ...

Abstract: This paper introduces a generic dynamic programming function for Matlab. This function solves discrete-time optimal-control problems using Bellman's dynamic programming algorithm. The ...

Learn how to make everything from basic line graphs to racing bar charts — all interactive and easily animated — with the echarts4r R package. While I’m mostly settled on ggplot2 for static plots, I’m ...
