DWT Based Blind Digital Video Watermarking Scheme for
Video Authentication




INTRODUCTION

Video is a three-dimensional array of color pixels. Two
dimensions serve as spatial (horizontal and vertical) directions of
the moving pictures, and one dimension represents the time
domain . Digital video offers a number of advantages over
analog video, including the ease of sharing and storage, no
degradation of data quality when replicated, easy and inexpen ....etc

Camelina sativa is an oilseed crop and it might be used as fuel in aircrafts in the near future. A study conducted at Michigan Technological University claimed that Camelina has shown to be one of the more promising alternatives to petroleum jet fuel. They studied the whole process i.e. from planting to airplaneâ„¢s tailpipe. David Shonnard, Robbins Chair Professor of Chemical Engineering, studied the carbon dioxide emissions of jet fuel made from Camelina oil ....etc

Pulse Shape Improvement in Core-Type High-Voltage Pulse Transformers With Auxiliary Windings
High-voltage pulsed power technologies are rapidly emerging as a key to efficient and flexible use of electrical power for many industrial applications. One of the most important elements in high-voltage pulse-generating circuit technology is the transformer, generallyused to further increase the pulse output voltage level. However, its nonideal behavior has significant influence on the output pulse shape.The most attractive winding configurati ....etc

Water Jet cutting services make use of a super high pressure stream of water that carries an abrasive grit. This abrasive mixes with the water through a venturi effect in what is commonly called the ?focusing tube? just prior to cutting. This mixture of water and abrasive grit exit the focusing tube at speeds of approximately mach 2.5. Cutting pressures range between 45,000 to 60,000 psi for standard cutting models. For brittle, fragile, or delicate materials, piercing pressures range between 15,000 to 20,000 psi, and resume the higher cutting ....etc

Abresive Jet Machine



It is a newly developed technology used in industrial countries. This is adopted for machining operations.


Features

In this machine a high velocity of abrasive stream is used for machining. The abrasive particle have a vibration of about 50 hertz is mixed with high pressure gas or air in the mixing chamber. Then the stream is emerges through a small nozzle mounted on a fixture to the work piece.
Variable in abrasive jet machine
The variables that influence the rate of metal removal and accuracy of machining ....etc

PULSE JET ENGINE
What is Pulse Jet ?
• Simple form of internal combustion engine
– Combustion occurs in pulses
» Termed deflagrations
» Characterized by sudden rise in temperature and pressure followed by a rapid subsonic expansion
– Propulsive effort is a rearward reaction to hot gases
HISTORY
• Patented in 1906 by Russian engineer V.V Karavodin
• In the 1933 German engineer Paul Schmidt re-discovered the princi ....etc
