circuit switched vs packet switched abstract seminar topic

In circuit switching network dedicated channel has to be established before the call is made between users. The channel is reserved between the users till the connection is active. For half duplex communication, one channel is allocated and for full duplex communication, two channels are allocated. It is mainly used for voice communication requiring real time services without any much delay

In packet switching network unlike CS network, it is not required to establish the connection i ....etc

This document presents a four-quadrant controller for switched reluctance motor (SRM) drives with optimal ignition and turning angles for each operating quadrant. Trigger angles are chosen to maximize the average torque produced by the motor, which requires optimizing the area of the power conversion loop. The four-quadrant SR controller developed with the chosen optimization criteria provides fast response in the engine as well as a rapid braking response. The underlying contribution of this work is the development and solution of an optimal c ....etc

ABSTRACT

This paper presents a scheme for designing a kind of wireless charging system aimed to provide power transmission for personal mobile devices such as cell phone. This scheme consists of three parts: wireless power transmission design, wireless signal transmission design and charging manage design. A circular array consisting of some antenna elements is employed in the scheme as transmit access of power and signal. In the supposed indoor condition, the transfer efficiency can up to 66%. The charging manage adopt a close-loop optimal ....etc

beam engine mini project report file download pdf

Abstract

A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt who added a separate condenser, Jonathan Hornblower and Arthur Woolf who compounded the cylinders, and William McNa ....etc

Wind-powered mobile phone charger
The project is developed by UK wind turbine specialists. It is seen as a solution to the problem of keeping your mobile phone fully charged when miles away from a conventional electricity source. The product is a a small, portable tent mounting mobile phone charger. It uses uses stored kinetic energy to charge the mobile phone. This is an ecologically friendly phone accessory and weighs only 150g. a conventional horizontal axis wind turbine is present alongwith a propeller diameter of 30cm. This in turn ....etc

smart antenna ppt free download in iee format

Smart antennas (also known as adaptive array antennas, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signature such as the direction of arrival (DOA) of the signal, and use it to calculate beamforming vectors, to track and locate the antenna beam on the mobile/target. Smart antennas should not be confused with reconfigurable antennas, which have similar capabilities but are single element antennas and not antenna ar ....etc
