Common mode rejection ratio (CMRR) is important performance parameter of any difference amplifier. It is the ratio of the differential gain to the common-mode gain, generally expressed in dB. It signifies the ability of an opamp to reject common mode signal, the signal which appears simultaneously at both its input terminals. The CMRR is of great importance when it comes to noise rejection. For applications involving high CMRR, instrumentation amplifiers consisting of three opamps are generally used. It has a major disadvantage that the value o ....etc

Abstract
Extracting minutiae from fingerprint images is one of the most important steps in automatic fingerprint identification and classification. Minutiae are local discontinuities in the fingerprint pattern, mainly terminations and bifurcations. In this work we propose two methods for fingerprint image enhancement. The first one is carried out using local hist ....etc

SOLUBILITY ENHANCEMENT TECHNIQUES




INTRODUCTION

A number of methodologies can be adapted to improve
solubilization of poor water soluble drug and further to
improve its bioavailability. The techniques generally
employed for solubilization of drug includes
micronization, chemical modification, pH adjustment,
solid dispersion, complexation, co‐solvency, micellar
solubilization, hydrotropy etc. Solubilization of poorly
soluble drugs ....etc

IMAGE ENHANCEMENT TECHNIQUES USING FREQUENCY DOMAIN FILTERING


Image Enhancement?
It is the process of making an image more pleasable than the original image.

Why needed?
Noise introduced in to the image, out-of focus , atmospheric conditions, latency of imaging hardware.

Applications

Medical imaging.
Satellite imaging.
Material testing in industries.
Fingerprint identification.
Printing and publishing industry.

Conclusion

Thus, image enhancement techniques in frequency domain improves the ....etc

INTRODUCTION
Image enhancement widely used in computer graphics.
It is the sub areas of image processing.
The principle objectives of image enhancement techniques is to process an image so that the result is more

suitable than the original image for a specific application .
METHODS FOR IMAGE ENHANCEMENT
Image enhancement techniques can be divided into two broad categories:

1.Spatial domain methods .
2 Frequency domain methods.
SPATIAL DOMAIN METHODS ....etc

POWER QUALITY ENHANCEMENT TECHNIQUES
ABSTRACT:
This paper presents operation and performance of a boost converter used for a power factor correction. The mode of operation of boost converter in continuous and discontinuous mode is explained which helps the input current to follow the input voltage, thus making the power factor unity. The correction converter reduces harmonic pollution and disturbance on the supply mains. This method is suitab ....etc
