have a computer system that would tell which guns needed to be pulled. You would have to look at the serial number on the gun, find the gun’s card in a cabinet and look up the date for when the gun would need to be pulled. This system is very inefficient, so Don decided to create such a system that would say when a specific gun would need to be pulled. Not only did Don do this for the weapons, but he did the same for drivers licenses, and many more small tasks for military. This was his kick

The main issue this work addresses is the probability of successfully shooting an enemy in XCOM, an alien-invasion turn based strategy game. Neil Brown, a computing education researcher, desires to analyze the chance of a player from hitting an alien target using computational mathematics. Two different methods of shooting (normal vs. rapid fire) are compared to provide the players with an idea on how to effectively and successfully shooting the enemies in different context (one shot vs. multiple

Catapults were one of the earliest forms of large weapons, in which projectiles were shot. “The general definition is that a catapult is a machine that stores energy then quickly releases this energy to fire a projectile,” said Kalif (Kalif, 2007). Catapults are basically a spring compressed together ready to release and explode into action. Catapults have been used in battle for many, many years shooting objects from rocks to fire balls. There are three main types of catapults including: the ballista

Lithgow Crossover   The Lithgow Crossover Rifle or the LA101 is an Australian-made varmint, hunting, and target firearm manufactured by Lithgow Arms, a small military arms factory in New South Wales, Australia with over 100 years of expertise. As such, users can expect the Crossover rifle to be one of the best in accuracy and reliability.   Basic Specifications (depends on calibre)  Length – 38.5 to 39.6 inches  Barrel Length – 20.9 inches  Weight – 6.8 pounds  Rate

Most of the crimes that are committed in our society involve a handgun. Gunshot wounds can be very challenging on determining whether or not it was a suicide attempt or homicide. There are some indicators that assist investigators reach a conclusion on gunshot wounds. One of the indicators is the location of the gunshot wound such as the entry and exit points. For example, as the bullet passes through the skin inward and can often travel through the body on a straight path. Furthermore, the damage

Ballistics (B5) Literature Review Evaluation of the possibility of differentiation between various types of ammunition by means of GSR examination with SEM-EDX method (2001) This paper assesses the use of a scanning electron microscope with an energy dispersive x-ray spectrometer (SEM-EDX) to analyse gunshot residue (GSR) and determine the type of ammunition used, as well as the gun it was fired from. GSR is the remains of the primer and propellant from the ammunition after a gun is fired. GSR

INTRODUCTION A taxi driver was killed during a night robbery in Columbia, South Carolina. Out of this rather ordinary crime, it had been boxed up for nearly four decade until 1997, when the sheriff department created a cold case squad. In 1961, John Orner was shot three times in the head because the suspect tried to remove any money from Orner’s taxi. Following morning, the bloodstained taxi was found abandoned within the streets of Columbia. Through ballistics evidence found in John Orner’s head

Introduction: From the incident, it can be reasonably suggested that the weapon must be small and concealable with a quick fire rate in order to eliminate two targets at once. The perforating wounds, wounds with entry and exit wounds, also suggest a high velocity firearm although the metal fragments in the wound from Victim 2 imply the bullet can be easily fragmented. The Heckler and Koch MP7 sub machine gun with 4.6 x 30mm frangible SX ammunition coincides with this evidence, especially with the

Imagine this, a cop shows up at 3 in the morning at your house to inform you that your son or daughter won’t be coming home anytime soon. Why? Because they were in the area that a shooting occurred, and sadly they were one of the several casualties. Your heart sinks, tears fill up your eyes, and there's a lump in your throat. This can’t be possible, how could this have happened you think. Now imagine this not having to occur. Families not having to lose their loved ones from the usage of guns (to

elastic energy forces the string to go forwards therefore transforming the elastic energy to kinetic energy which transfers into the arrow when the string reach’s limit of extension. Catapult The catapult uses centrifugal force to accelerate the projectile toward the
