Buck-Boost Powerformer



Jefferson Electric single-phase Buck-Boost transformers are the most economical means available
for stepping voltages up or down in many common applications. They can be used as isolating (or
insulating) transformers for transforming standard line voltages to low secondary voltages. They are
also used to buck or boost off-standard line voltages to satisfy standard load voltage requirements
when connected in an autotransformer configuration.
These transformers are designed for us ....etc

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

A washing machine (laundry machine, clothes washer, or washer) is a machine used to wash laundry, such as clothing and sheets. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids, and is performed by specialist businesses) or ultrasonic cleaners.A washing machine is a machine that washes dirty clothes. It contains a barrel into which the clothes are placed. This barrel is filled with water, and then rotated very quickly to make the water remove dirt from the clothes. Most wash ....etc

First talk about what is Virtual Reality? Virtual reality is an artificail environment or scene that are created by using hardware devices and software of a computer. This artificial scene or environment is presented in such a manner that it look and appears 3-D and we feel like a 3-D world.
To experience a vitual reality scene or environment, a user requires a head- mounted display (HMD) and special types of gloves which receives input from the computer. A HMD keeps a track on how eyes move and responds by sending a new input video. Also a use ....etc

The slotted links AM and BH are attached to the front wheel axle, which turn on pivots A and B respectively. The rod CD is constrained to move in the direction of its length, by the sliding members at P and Q. These constraints are connected to the slotted page link AM and BH by a sliding and a turning pair at each end. The steering is affected by moving CD to the right or left of its nominal position.


The Davis steering is an exact steering gear mechanism.the slotted links AM and BH are attached to thefront wheel axle, which turns on piv ....etc

disadvantages and advantages for optimal jamming attacks in ppt

Abstract

We consider a scenario where a sophisticated jammer jams an area in a single-channel wireless sensor network.The jammer controls the probability of jamming and transmission range to cause maximal damage to the network in terms of corrupted communication links. The jammer action ceases when it is detected by a monitoring node in the network, and a notification message is transferred out of the jamming region. The jammer is detected at a monitor node by employing an optima ....etc

POWERFORMER



Introduction
Today s high-voltage generators are constructed in such a way that limits their output voltage to a maximum of 30 kV. Those generators cannot, directly supply the power grid with voltages up to 800 kV, a reason why large power plants nowadays are using power step-up transformers in order to transform their generated voltage to a higher voltage level suitable for the interface with the transmission grid.
The step-up transformer imposes great drawbacks o ....etc
