Colonel Shaw's Plan of Muzzle-Pivoting Guns

An Accurate Method to Determine the Muzzle Leaving Time of Guns

This paper states the importance of determining the muzzle leaving time of guns with a high degree of accuracy. Two commonly used methods are introduced, which are the high speed photography method and photoelectric transducer method, and the advantage and disadvantage of these two methods are analyzed. Furthermore, a new method to determine the muzzle leaving time of guns based on the combinat...

Muzzle velocity measurement radar

The abundance of information provided by the Internet is characteristic nowadays but knowledge transfer in high-tech issues/subjects is generally limited and only concentrating on users/utilization. The researcher/producer companies are not interested in deep knowledge sharing of equipment and thereby jeopardizing the revenue and profits from production. Thus, the author does not rely on variou...

FPGA Based Muzzle Velocity Measurement System

Muzzle velocity is the initial velocity of a projectile as it comes out. A novel measurement method which can measure velocity of projectile by measuring its travel time. It mainly contains the laser sources and laser detectors those are employed to measure the muzzle velocity, when it comes out of a system. Light sources and detectors are placed in opposite side. During system launch, the lase...

Stability of the Diagonal Pivoting Method with Partial Pivoting

LAPACK and LINPACK both solve symmetric indefinite linear systems using the diagonal pivoting method with the partial pivoting strategy of Bunch and Kaufman [Math. Comp., 31 (1977), pp. 163–179]. No proof of the stability of this method has appeared in the literature. It is tempting to argue that the diagonal pivoting method is stable for a given pivoting strategy if the growth factor is small....
