Use of a custom designed external fixator system to treat ballistic injuries to the mandible
International Journal of Oral and Maxillofacial Surgery, 2011The authors describe a custom designed mandibular external fixator II system that can be used to treat complex, comminuted fractures. The system is adjustable and lightweight, quick, robust, simple to apply, and allows mouth opening during healing, It is well suited to use in the modern war surgery environment.

Influence of pellet seating on the external ballistic parameters of spring-piston air guns
International Journal of Legal Medicine, 2016In firearm examiners' and forensic specialists' casework as well as in air gun proof testing, reliable measurement of the weapon's muzzle velocity is indispensable. While there are standardized and generally accepted procedures for testing the performance of air guns, the method of seating the diabolo pellets deeper into the breech of break barrel ...

About the First Integral in the Classical Problem of External Ballistics
Prikladnaâ matematika i mehanikaThe transcendental first integral of the classical problem of external ballistics has been retrieved from oblivion. A change of variables was proposed that transformed the integral to a compact form. This allowed for reducing the solution of the problem to constructive quadratures.

Modeling and Simulation of External Ballistics of New Air-Defence Guided Projectile
2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2019The method of three-dimensional ballistic modeling and simulation of shipborne air-defence guided projectile is discussed. Firstly, the force and guidance law of the projectile are analyzed, and taking the proportional guidance as an example, the method establish the simulation model of the air-defence guided projectile ballistic from the perspective ...

Fractional hyper-ballistic transport under external oscillating electric fields
Chaos: An Interdisciplinary Journal of Nonlinear ScienceThe generalized Langevin equation (GLE) for a tagged particle in a liquid of charged particles under the influence of external AC electric fields is studied. For the fractional memory kernel in the GLE, the mean square displacement (MSD) of the particle is studied analytically in both the underdamped and overdamped regimes.

Analysis of External Ballistics for a Projectile of Caliber 155 MM
2017The objective of this thesis is to propose a geometry for a projectile to firefighting. The finite volume code STAR − CCM+® is used to calculate forces and moments acting on the projectile and a code is created in MATHEMATICA® to define the characteristics of the trajectory. The PRODAS® is used to verify and validate the models implemented.
