Long (L>>λpe) charged particle bunches traveling in dense plasmas are subject to a transverse two-stream instability, the self-modulation instability (SMI)1. This instability modulates the bunch in the radial direction with a longitudinal period approximately equal to the plasma wavelength (λpe∼ne1/2). The SMI can be used to transform a long bunch into a train of short bunches that can resonantly...
This paper reports an empirical evaluation of four black-box testing techniques for crashing programs through their GUI interface: SH, AF, DH, and BxT. The techniques vary in their level of automation and the results they offer. The experiments we conducted quantify execution time and the capability of finding a crash for each technique on 8 different cellular phone configurations with historical...
