Technical Analysis is the forecasting of future financial price movements based on an examination of past price movements. technical analysis can help investors anticipate what is "likely" to happen to prices over time. Technical analysis uses a wide variety of charts that show price over time. Definition 1: A method of evaluating future security prices and market directions based on statistical analysis of variables such as trading volume‚ price changes‚ etc.‚ to identify patterns.

Elliot Wave cycle is composed of 8 sub waves. 5. 5-wave Elliot upward motive impulse wave‚ the longest and most dynamic is the third wave. 6. Long-term price movements with volatility – logarithmic 7. Not a continuation pattern – broadening formation 8. According to Dow theory‚ secondary corrections can most likely be replaced

GAS DYNAMICS AND JET PROPULSION 1. What is the basic difference between compressible and incompressible fluid flow? Compressible 1. Fluid velocities are appreciable compared with the velocity of sound 2. Density is not constant 3. Compressibility factor is greater than one. 2. Write the steady flow energy equation for an adiabatic flow of air. In an adiabatic flow q = 0. Therefore energy equation becomes. 2 c12 c2 h1 + + gZ1 = h2 + + gZ 2 + Ws 2 2 Incompressible 1. Fluid velocities are small

Crumple zones are one of the greatest innovations made with cars to protect the passengers in the event of an auto accident. Crumple zones cause impulse‚ or the change in momentum when an object acts on by a force for a certain amount of time. Though first‚ we need to know why crumple zones were made. An average of almost 1.3 million people die from nearly 5.5 million car accidents around the world annually. Along with this 20-50 million people are either injured or disabled in the wrecks. This
