CLASS-D AMPLIFIERS
Abstract
Class D amplifiers present us with a revolutionary solution, which would help us eliminate loss and distortions caused due to conversion of digital signals to analog while amplifying signals before transmitting it to speakers. This inchoate piece of knowledge could prove to detrimental in improving and redefining essence of sound and take it to a different realm.

This type of amplifiers do not require the use of D-A conversion and hence reduce the costs incurred for dev ....etc

DIGITAL IMAGE TRACING BY SEQUENTIAL MULTIPLE WATERMARKING
Abstract
The possibility of adding several watermarks to the same image would enable many interesting applications such as multimedia document tracing, data usage monitoring, and multiple property management. In this paper, we present a novel watermarking scheme, which allows inserting and reliably detecting multiple watermarks sequentially embedded into a digital image. The proposed method, based on elementary linear algebra, is asymmetric, secure under pr ....etc

ABSTRACT
The biggest obstacle to the multimedia revolution is digital obesity. This is the blot that occurs when pictures, sound and video are converted from their natural analog form into computer language for manipulation or transmission. In the present explosion of high quality data, the need to compress it with less distortion of data is the need of the hour. Compression lowers the cost of storage and transmission by packing data into a smaller space.
One of the hottest areas of advanced form of compress ....etc

ABSTRACT

Power quality is essential for smooth functioning of industrial process. As industries expand, utilities become more interconnected and usage of electrically equipment increases, power quality is jeopardized. The quality of power in the power system is severely affected by the presence of harmonics. This harmonics adversely effects the power system performance. Some of the effects are over heating of metal parts, noise in motors, low efficiency in motors etc. The effects produced by the harmonics are reduced by a ....etc

Technology has advanced to the point where realism in virtual reality is very achievable. However, in our obsession to reproduce the world and human experience in virtual space, we overlook the most important aspects of what makes us who we are”our reality. One must capture the imagination in order to create truly compelling experiences.Augmented reality will truly change the way we view the world. Picture yourself walking or driving down the street.

Image Processing and Analysis


Introduction
Image Processing and Analysis can be defined as the act of examining images for the purpose of identifying objects and judging their significance Image analyst study the remotely sensed data and attempt through logical process in detecting, identifying, classifying, measuring and evaluating the significance of physical and cultural objects, their patterns and spatial relationship.

Digital Data
In a most generalized way, a digital image is an array of numbers depicting spati ....etc

ABSTRACT
We propose a new method for strengthening the security of information through a combination of signal processing, cryptography and steganography. Cryptography provides the security by concealing the contents and steganography provides security by concealing existence of information being communicated. Signal processing adds additional security by compressing and transforming the information. The proposed method, viz. Steganography Based Information Protection Method (SBIPM), consists of scanning, coding, encry ....etc

Abstract:
Voltage sag are the major source of power quality related problems. Dynamic Voltage restorers (DVR) are used to protect sensitive loads from the effects of voltage sag on the distribution feeder. It injects voltage in series with the system voltage to compensate the sag. This paper presents a power system operation with PI controller approach. Total Harmonics Distortion (THD) is calculated for the system in absence of compensation scheme next THD is evaluated when DV ....etc

INTRODUCTION:
AMPLIFIER:
A circuit that increases the amplitude of a given input signal is called an amplifier. A small a.c. signal fed to the amplifier is obtained as a larger a.c. signal of the same frequency at the output.Amplifiers constitute an essential part of radio, television and other communication circuits. Bipolar junction transistors and Field effect transistors are commonly used as amplifying elements.
Amplifiers can be classified as follows:
1. Based on transistor conf ....etc

AUGMENTED REALITY
ABSTRACT

Video games have been entertaining us for nearly 30 years, ever since Pong was introduced to arcades in the early II 970â„¢s.Computer graphics have become much more sophisticated since then, and soon, game graphics will seem all too real. In the next decade, researchers plan to pull graphics out of your television screen or computer display and integrate them into real- world environments. This new technology called augmented reality, will further blur the line between what ....etc

ABSTRACT
Hypersonic sound technology from American Technology Corporation employs ultrasonic waves to create audible sound in the air. It works by using harmless ultrasonic tones that we can't hear. These tones use the property of air to create new tones that are within the range of human hearing. The result is audible sound. The acoustical sound wave is created directly in the air molecules by down-converting ultrasonic energy to the frequency spectrum we can hear. Hyper Sonic Sound is produced without the excess bag ....etc
