Since the earliest days of aviation, effective communication between ground staff and pilots has been a key component of safe flying of aircraft. Every information the pilot might get or share with the ground staff can be crucial, and it might save the lives of both the aviation personnel and the passengers. Although aviation communication seems to be a very simple thing to do now, it was one of the most complicated things during the early stages of aviation. Since December 17th, 1903, when the Wright brothers made the first successful flight in history, communication with pilots in the air has been a real challenge. fig:1 Visual aids like colored paddles, signal flares, and hand signs were used at the beginning as means of communication. However, the first air-to-ground radio communication used Morse code and operators used short signals in order to save time. In the times when messages were sent via telegraph (in Morse code), one of those short signals that wer...

Differentiation represents the rate of change of a function.  Integration represents an accumulation or sum of a function over a range.  They are kind of inverses of each other. Let’s consider an example.  If you have a tank of water with a small hole at the bottom, the water would leak out and the water level would drop in the tank.  It should be obvious from common experience, that when the tank is full, the water will spurt out faster than when the water level is very low when the water flow is just a trickle.  The amount of water leaking out each second is a rate of change, that is the differentiation of the amount of water in the tank with respect to time, so when the water level is high we have a high rate of change and when its low we have a low rate of change - we write this mathematically as dV/dt. Now, suppose we had a bucket under the hole and we collect the leaked water.  Obviously, the amount of water in the bucket will increase over ti...

Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around.

this is one of my favorite hobbies.This pics reminds me to go back to one memorable day near Baletaksaar Gulmi, WEST Nepal while i was travelling to home ..with some friends .. m sharing my  day here.. thanks for clicking..

Hii this is my first day to post this text here . i am very  eager to understand it ..

The resistor is a passive electrical component to create resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals. The current is proportional to the voltage across the terminal ends. This ratio is  represented by  Ohm’s law : Read more  http://www.resistorguide.com/what-is-a-resistor/ Resistors are used for many purposes. A few examples include delimit electric current, voltage division, heat generation, matching and loading circuits, control gain, and fix time constants. They are commercially available with resistance values over a range of more than nine orders of magnitude. They can be used to as electric brakes to dissipate kinetic energy from trains, or be smaller than a square millimeter for electronics. Resistor d...
