On Guns and Cail's Rifled Projectiles

Guns, Privacy, and Crime

We investigate the impact of an information shock – the public exposure of the names and addresses of holders of handgun carry permits – on criminals’ propensity to commit crimes. In December 2008, a Memphis, TN newspaper published a searchable online database of names, zip codes, and ages of Tennessee handgun carry permit holders. Once news of the database publication spread, an intense and ac...

On the Air Resistance of Projectiles.

on semihypergroups and hypergroups

in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

Microspoiler Actuation for Guided Projectiles

The goal of this project was to further mature microspoiler technology to the extent that it could be incorporated into current and future smart weapons designs. Several program objectives, including mechanical design and fabrication, trade study analysis, and limited flight experiments were defined as a collaborative effort between the Georgia Institute of Technology (Georgia Tech) and the Arm...
