Pressure Hydraulics Company in the given context, which is having trouble with their accounting and employees processes. We put forward that this problem can be solved only by means of an automated transaction processing system, which will support the business farm in all the commercial purposes such as storage, collection, recovery and modification of all transaction related information within the organization. In accordance to the problems the company is facing as described in

ABSTRACT This article reviews the history of free piston internal combustion engines with its advantages over traditional engines and applications. In this research paper unique characteristics of free piston engine are reviewed and working of this engine is discussed with its successful application in air compressor and gas generator. Finally this article reviews the history, working, advantages and applications of free piston engine. INTRODUCTION A free engine is a thermal engine having linear

the driver to change the gears as per driving needs. In a country like India, automatic transmission gives only a driving pleasure to the driver in heavy traffic as there is no need of changing gears because of the fact that it lacks a clutch paddle system which gives complete rest to one leg of the driver. Manual transmission fails to provide such an added benefit to drivers. But in developing countries, the idea of an automatic transmission is not wise and applicable to all due to the economic

e. The drainage area above the channel was greater than 64 acres and therefore required a COA, fully developed 100-year floodplain analysis using the Army Corp of Engineer’s HEC-RAS hydraulic modeling software. The proposed drainage easement delineated to contain the fully developed 100-year floodplain and added to the final plat; with minimum finished floor elevations calculated for all lots adjacent to any channel within the final plat

area. The revolving hydraulic trailor overcomes the problem of unloading the vehicle on side way by using hydraulic cylinder. By using cylinder the material can be unloaded in 180 degree as per requirement. The revolving hydraulic trailor is developed and tested for its movement in all 180 degree possible angle to unload the materials in the tipper trolley and monitor the inclinations for its gradualism (linearity). Key words: Design Optimization of Worm Gear drive, Hydraulic Cylinder, Worm & Worm

that drives by itself? Part of your dreams might become reality soon, as Google engineers have already had test drove their newly developed self-driving car on more than 180,000 miles of highways and roads! Picture: Fictional Self-Driving Car, Herbie There are already cars that can park themselves, but a self-driving car would be able to capture images of the road, identify alternative route and prevent traffic even before human eye can detect it. Wouldn’t it be fun to have a car that drives by itself

Speed control of ball screw is usually done with the help of feedback control system. The speed of ball screw driver is perceived and feedback to the control system and then, the appropriate controller such as Proportional & Integral or as extra Derivative to Proportional & Integral, Proportional controller etc. any of them can be implemented to follow the speed when commanded input to the control system. The basic working principle of these controllers is this that, they vary the voltage

Fracking: A growing scientific controversy The drive to satisfy the nation's insatiable appetite for energy has driven over 31 states to adopt a process of natural gas extraction known as hydraulic fracturing. "Used in nine out of 10 natural gas wells," fracking entails pumping "millions of gallons of water, sand and chemicals"¦to break apart the rock and release the gas" (What is hydraulic fracking, 2013, Pro Publica). The chemicals are necessary to transform the water "into a frictionless mass

Heart pounding, you carry on with your drive, shaking your head at the close call and the chicken’s lack of judgement in choosing this particular moment to cross the road. Your brakes worked flawlessly, arresting the motion of a multi-ton object traveling

motors. n.d.). 4.3 Negatives Speed Control: the main disadvantage of AC motors, is that their speed is difficult to control. AC motors can be operated with variable frequency drives that provides smooth turning torque, at low speeds and get control over the speed of the motor up to its suggested value. Variable frequency drives enhance speed control, but create losses with low power quality. Control Complexity: another significant disadvantage is that an AC motor controller must convert AC electricity
