An Affine Combination of two LMS adaptive filters transient mean square analysis

Abstract:
The design of many adaptive filters requires a tradeoff between convergence speed and steady-state mean-square error (MSE). A faster (slower) convergence speed yields a larger (smaller) steady-state mean-square deviation (MSD) and MSE. This property is usually independent of the type of adaptive algorithm, i.e., least mean-square (LMS), normalized least
Mean-square (NLMS), recursive least squares (RLS), or affine projection (AP).
This design tradeo ....etc

Affine Transformation Resistant Watermarking Based on Image Normalization

ABSTRACT

Geometric attacks are among the most challenging problems in present day watermarking. Such attacks are very simple to implement yet they can defeat most of the existing watermarking algorithms without causing serious perceptual image distortion. In this paper we propose a new public watermarking algorithm, which is robust to such attacks. This algorithm uses a normalized with respect to affine transformation representation of the imag ....etc

A MODULAR FUEL CELL, MODULAR DC–DC CONVERTER CONCEPT FOR HIGH PERFORMANCE AND ENHANCED RELIABILITY
ABSTRACT
Fuel cells are electrochemical devices that process H2 and oxygen to generate electric power, having water vapor as their only by-product. The voltage resulting from the reaction of the fuel and oxygen varies with the load, and ranges from 0.8 V at no-load to about 0.4 V for full-load. Due to their low output voltage, it becomes necessary to stack many cells in series to realize a practical system. The propos ....etc

ROBUST VARIABLE STEP-SIZE AFFINE PROJECTION ALGORITHM SUITABLE FOR ACOUSTIC ECHO CANCELLATION



ABSTRACT

The affine projection algorithm (APA) and different versions
of it have proved to be very attractive choices for acoustic
echo cancellation (AEC). In this context, a classical APA
with a constant step-size has to compromise between two
performance criteria, i.e., 1) high convergence rates and
good tracking capabilities, and 2) low misadjustment and
robustness against background noise variations and ....etc

I T's Challenge

In the past three tears, the world has changed for information technology groups. In the late 1990s, the predominant problem was deploying equipment and software quickly enough to keep up with demand for computing. While the tech sector boomed on Wall Street, money was no object. IT budgets swelled and the numbers of computers in data centers grew exponentially.

Now, in the early 2000s, the picture is very different. IT budgets are flat down, yet business demand for IT services continues to escalate. This co ....etc
