Sketch 'n Solve is a Python library that implements basic randomized numerical linear algebra (RandNLA) techniques for solving large-scale linear algebra problems. The library is designed to be ...

Abstract: This paper proposes a waveform design technique for dual-function radar-communication (DFRC) systems that employ hybrid linear-nonlinear precoding (HLNP). The HLNP signal is a superposition ...

In an approach reminiscent of the classic board game "Battleship," Stanford researchers have discovered a way to characterize ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

By focusing on a few core station types and committing to routines, teachers can boost engagement and student understanding.
