Mesh Algorithms in Parallel Processing

¢ Parallel processing is processing a task with several processing units, or many processors

¢ Most powerful computers contain two or more processing units that share among themselves the jobs submitted for processing

¢ Several operations are performed simultaneously, so the time taken by a computation can be reduced.

¢ A problem to be solved is broken into a no.of subproblems. These subproblems are now solved simultaneously, each on different processors. The results are then combi ....etc

New approach in steganography by integrating different LSB algorithms and applying randomization concept to enhance Data Security
ABSTRACT:
In this paper we propose a new technique in steganography to hide the information to be hidden with digital image. Here we take BMP image to hide the data. We take most common Steganography algorithm LSB as base and made some changes in it based upon our innovative idea that is integration of first LSB algorithm and second LSB algorithm. ....etc

When reference signal for the FxLMS algorithm is taken from an acoustic sensor convergence can be very slow due to great eigen value spread. Using a non acoustic sensor, Such as a tachometer, cancellation of narrow band noise in the sensed fundamental frequency and harmonically related ones can be achieved very fast, although other periodic noises and underline broad band noise will remain.

In this technical paper we present a study of the various routing algorithms, which are in use presently. This study of present algorithms is limited to their general working and the various security problems, which they are unable to solve. Our main emphasis is on discussing a novel approach based on Leap-Frog cryptographic signing protocol and that how this novel approach deals the various security threats, which, its predecessors (using traditional public-key signature schemes) are unable to withstand.

ABSTRACT
A randomized algorithm is defined as an algorithm that typically uses the random
bits as an auxiliary input to guide its behavior. It achievs good performance in the
average case. Formally, the algorithm's performance will be a random variable
determined by the random bits, with (hopefully) good expected value. The worst case is
typi ....etc

In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the Internet can be further harnessed in an efficient manner. It has been increasingly used by various continuous media applications such as teleconferencing, distance learning, and voice & video transmission. Compared with unicast and broadcast, multicast can save network bandwidth and make transmission more efficient. In this seminars, we will review the history of the multicast, present you several existing multicast routing algorithms ....etc
