This is a network protocol which enables a client in a NAT (or multiple NATs) to find out its public address, the type of NAT behind it and the internet side port associated by the NAT with a particular local port and this whole process aids to set up UDP communication between two hosts that are both behind NAT routers. STUN stands for Simple Traversal of UDP (User Datagram Protocol) through NATs (Network Address Translators).

Protocol overview

STUN is a client-server protocol. Any VoIP phone or software package includes a STUN client, wh ....etc

gun drilling

Gun drilling is a process that produces deep, straight holes in a variety of materials. A gundrill tool differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective cutting edge. Guide pads burnish the hole while drilling, allowing the hole to maintain straightness. The result of this burnishing activity is a very round hole with a precision diameter.

The Hydraulic system pressure can be generated in the form of any physical action which result a compression over the Hydraulic system or pneumatic pressure which is developed in the form of air compressing externally can be applied to activate Hydraulic system. There is a constant relation between pressure density, and volume, According to Bernoulli s equation. Liquids can be heated by applying high pressure without any external heat energy supplied to them. So the specific heat of any liquid system which is used in the hydraulic machinery mu ....etc

Machine Guns
Introduction
To understand how machine guns work, it helps to know something about firearms in general. Almost any gun is based on one simple concept: You apply explosive pressure behind a projectile to launch it down a barrel. The earliest, and simplest, application of this idea is the cannon.
A cannon is just a metal tube with a closed end and an open end. The closed end has a small fuse hole. To load the cannon, gunpowder (a mixture of charcoal, sulphur and potassium nitrate) is poured ....etc

INTRODUCTION
Since the conventional solid gun propellants have reached the saturation level in terms of energy output, a need exists for the development of high performance propellants for futuristic gun ammunition to propel hypervelocity projectiles. Hypervelocity guns are the guns having muzzle velocity in excess of 2000 m/s. Modern tank guns have muzzle velocity in the range of 1600 2000 m/s. With continuous improvement in armour technology, improved weapons with high muzzle velocity are under develo ....etc
