I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

Abstract: Principle of similarity of trajectories in electric fields which are homogeneous in Euler terms is an effective instrument in charged particle optics. However, the set of electrical ...

Abstract: We address the problem of practical stabilization of driftless nonlinear control systems with homogeneous vector fields. A general feedback design approach, based on the concept of ...
