A coil-gun uses pulsed currents of large magnitude to propel ferrous projectiles at high speeds. The various problems associated with high currents and magnetic fields are discussed, as well as the components and design of my experimental coil-gun. I tested the coil-gun at various charge voltages and different projectile sizes, then calculated the efficiency of the coil-gun with measured values...
SPARROW is a stochastic local search (SLS) solver for SAT formulae in CNF format [2]. It was named after the mascot of the German city of Ulm. SPARROW2011 is a variant of SPARROW that was developed for the 2011 SAT competition. The core SPARROW2011 algorithm is identical to SPARROW; it has been re-implemented in UBCSAT [9] and a mechanism has been added to automatically select optimized paramet...
Abstract The high temperature and pressure gas in the combustion chamber pushes projectile towards muzzle during firing of gun. belt is squeezed deformed by forcing cone. In order to study dynamic engraving characteristics projectile, a short-barrel gun launcher was designed for experimental research. dynamics base curves process were obtained. Based on loading conditions, J-C elastic-plastic m...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
We present an unusual case of chlorobenzylidenemalonitrile (CS) tear-gas exposure from the unwitting discharge of a personal-protection handgun loaded with CS gas. The gun was in a bag of toys purchased from a local thrift store and was discharged by a child. The responding paramedic presumptively identified the substance as CS based solely on personal experience. This recognition led to subopt...
this is a case of a patient with bowel obstruction , imaging studies were suggestive for pneumatosis intestinalis. clinically diagnosed as adhesion band and pnematosis intestinalis. she underwent laparatomy, enterolysis, obstructionolysis and enterorrhaphy. the patient developed respiratory distress and expired after 2 days. at autopsy we found gray-brown discoloration in the wall of some part ...
Abstract Aiming at the problem of accurate latch opening control expansion wave gun automatic gun, mathematical model time is established, travel curve projectile and wave, velocity are studied, occurrence close to simulated analyzed; The time-space evolution relationship between local sound velocity, gas simulated; average pressure chamber resultant force two launch modes compared analyzed. Af...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
BACKGROUND Penetrating neck injuries result from missiles and stab wounds. A gas pistol is a non-lethal weapon for self-defence. CASE REPORT We present a case where the use of a modified gun led to multiple injuries in a single shot. Four projectiles were embedded in the neck, one in the larynx and three in the cervical spine. The first was removed via a combined external and endoscopic appro...
