The Sonic RAREFACTION WAVE GUN (RAVEN) is a Projectile Launch Method that achieves: – Unprecedented Reductions in Recoil Impulse. It can shoot faster, cooler and can be lighter than a current gun ...

The compressible Navier-Stokes equations form the cornerstone of fluid dynamics, describing the motion of viscous compressible fluids under conservation of mass, momentum and energy. By incorporating ...

Rarefaction has long represented a powerful tool for detecting species richness and its variation across spatial scales. Some authors recently reintroduced the mathematical expression for calculating ...

Inspired by the paper folding art of origami, a University of Washington team created a paper model of a metamaterial that uses 'folding creases' to soften impact forces for potential applications in ...
