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 poure ....etc

Aircraft egress and ejection is a complex mechanism to remove the occupant safely, but quickly, from a doomed aircraft. Most military aircraft, research aircraft and some small commercial airplanes are equipped with ejection seats to allow pilots to escape from damaged or malfunctioning airplanes.


Ejection seats are one of the most complex pieces of equipment on any aircraft, and some consist of thousands of parts. The purpose of the ejection seat is simple: lift the pilot straight out of the aircraft to a safe distance, then deploy a para ....etc

ABSTRACT
Micro air-vehicle is a small flight vehicle that uses a lift-generating mechanism that is different from the mechanism used for large aircrafts. In micro air- vehicles, one of the methods for creating lift is a special flapping mechanism, which consists of translation and rotational motions of wings. This is adopted from one species of insect Encarsia Formosa. For this purpose, a 6-link mechanism is designed for three positions of wings by synthesis using kinematic inversion, and dynamic force ....etc

EJECTION SEAT



ABSTRACT
Almost since the first days of flight man has been concerned with the safe escape from an aircraft which was no longer flyable. Early escape equipment consisted of a recovery parachute only. As aircraft performance rapidly increased during World War II, it became necessary to assist the crewmen in gaining clear safe separation from the aircraft. This was accomplished with an ejector seat which was powered by a propellant driven catapult - the first use of a ....etc

ABSTRACT


MICRO AIR VEHICLES




Have you ever thought of a class of air vehicles which are less than 15 cms in size (most prominent linear dimension), can hover for two to three hours in air at a velocity of 20 to 30 mph at an altitude of 600 meters or even higher. This seminar will give you an idea of such vehicles called MAVâ„¢s (micro air vehicles). A dwell into the design and aerodynamics of such vehicles would be quit ....etc

CHAPTER-1
IMAGE SEGMENTATION
1.1 INTRODUCTION TO THE PROJECT:
An image may be defined as two dimensional fumction as f(x,y), where x and y are spatial (plane) coordinates and the amplitude of f at any pair of coordinates (x,y) is called the intensity or gray level of the image at that point.
When x,y and the amplitude values of f are all finite discrete quantities , we call the image a digital image. The field of digital image processing refers to processing digital images by a digital compute ....etc
