Johns Hopkins APL and GKN Aerospace are partnering to develop a system that simulates shipboard motion for metal 3D printing at sea — advancing the Navy’s ability to produce critical parts on demand.

Abstract: This article focuses on the robust output regulation problem with prescribed performance for uncertain second-order nonlinear systems with non-polynomial nonlinearity. According to the ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...
