hydraulic intensifier is a hydraulic machine to transform hydraulic energy at low pressure in a volume reduced to a higher pressure

Such a machine can be built by mechanically linking the two pistons, each working in a cylinder separated with a different diameter. As the pistons are mechanically connected, their strength and their stroke length are the same. If the diameters are different, the hydraulic pressure in each cylinder varies in the same ratio as their areas: the small piston giving birth at a pressure more high. When the pressure ....etc

Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc

advantages:
Enabling women by placing them in typically male industries usually means an increase in security. FMC mines love to employ women in their mines because although women will have to work slower due to physical limitations, this allows for a general increase in safety; Fewer injuries on site and, of course, fewer deaths. In the direction, the woman asks more questions, is generally less competitive, and will admit more willingly when she does not understand something. Men are not smarter than women; Women are more vocal ....etc

digital clock using 8051 advantages and disadvantages

Digital clock displays the time using numbers. This circuit is used in many applications like cars, railway stations, houses, offices, etc. in order to provide accurate time and date. In this type of applications, normally we use RTC (Real Time Clock) ICs to display the time and date accurately. This circuit displays the time on LCD. For this clock, we can set the time at any instant. Here the clock works in 24 hour mode and the RTC chip is configured by programming 8051 controller.

Circui ....etc

INTRODUCTION

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz to 3GHz for mob ....etc

Phishing is the attempt to obtain sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money), often for malicious reasons, by masquerading as a trustworthy entity in an electronic communication. The word is a neologism created as a homophone of fishing due to the similarity of using a bait in an attempt to catch a victim. Communications purporting to be from popular social web sites, auction sites, banks, online payment processors or IT administrators are commonly used to lure unsuspecting vi ....etc

Object counter using 8051 microcontroller.
This article is about a simple object counter/visitor counter using 8051 microcontroller . AT89S51 belonging to the 8051 family is the microcontroller used here. This circuit can count the number of objects passing across a line , number of persons passing through a gate/door and so on. The can be simply divided into two sections i.e. the sensor section and the display section.

Sensor.

The sensor part consists of a ultra bright led (with focus), and LDR, opamp LM324 and the associated passive co ....etc
