Abstract:
In this paper, the authors propose a new steganographic scheme based on vector quantisation (VQ) andsearch-order coding (SOC).The capacity of the proposed scheme is higher than others based on VQand the quality ofstego-image is acceptive. In general, the capacity of the schemes based on VQ is usually 1-bit per block. In 2004, Yuet al. proposed a scheme to increase the capacity to 3-bit per pair of blocks. In the proposed scheme, the authorsutilised multiple codebooks and chose the combinations of per pair of blocks, to embed ....etc

Abstract
This paper proposes a generalized method for thegeneration of space vector pulsewidth modulation (SVPWM) signalsfor multilevel inverters. In the proposed method, the actualsector containing the tip of the reference space vector need notbe identified. A method is presented to identify the center of asubhexagon containing the reference space vector. Using the centerof the subhexagon, the reference space vector is mapped to theinnermost subhexagon, and the switching sequence correspondingto a two-level inverter is determined. A n ....etc

As we enter the age of universal electronic connectivity, electronic eavesdropping and electronic fraud threaten the prosperity of corporations and individuals. Thus, the role of digital security has become increasingly important. The security requirements within an organization have undergone major changes in the last few decades. Before the widespread use of data processing equipment, data and information valuable to an organization were made invulnerable primarily by physical and administrative means.

STEGO- HUNTER: ATTACKING LSB BASED IMAGE STEGANOGRAPHIC TECHNIQUE
ABSTRACT
Steganography is the process of hiding secret information in a cover image. Our aim is to test a set of images for statistical artifacts due to message embedding in color images using LSB insertion method and to find out, which images out of them are likely to be stego. In a natural uncompressed image (i.e. 24bit BMP) each image is represented by three color channels (Red, Green and Blue), each of ....etc

A detailed look at Steganographic Techniques and their use In an Open-Systems Environmen]t
I. Introduction
This paper's focus is on a relatively new field of study in Information Technology known as Steganography. This paper will take an in-depth look at this technology by introducing the reader to various concepts of Steganography, a brief history of Steganography and a look at some of the Steganographic techniques available today. The paper will close by looking at how we can use Steganography in an open-systems env ....etc

A New Simplified Space–Vector PWM Method for Three-Level Inverters


I. INTRODUCTION
RECENTLY, with the dramatic improvements in high
voltage technologies, high voltage insulated gate bipolar
transistor (HVIGBT) and gate commutated thyristor (GCT) are
expanding the area of their application. For the high performance
ac drive systems at increased power level, high quality
inverter output with low harmonic loss and torque pulsation
is necessary. In case of the conventional ....etc
