A distributed system consists of independent workstations connected usually by a local area network. Load Balancing system puts forward to a new proposal to balance the server load in the distributed system. The load balancing system is a set of substitute buffer to share the server load, when their load exceeds its limit. The proposed technique gives an effective way to overcome the load balancing problem. Serving to more number of client requests is the main aim of every web server, but due to some unexpected load, the server performance may degrade. To overcome these issues, network provides an efficient way to distribute their work with the sub servers which is also known as proxy servers. Allocating work to the sub server by their response time is the proposed technique. The secure socket layer with Load balancing scheme has been introduced to overcome those server load problems. Storing and serving effectively and securely is more important so that desired algorithm is going to implement for load distribution and security enhancement named as Secure Socket Layer with Load Balancing and RSA Security algorithm respectively. Calculating response time of each request from the clients has been done by sending an empty packet over the networking to all the sub servers and response time for each sub server is calculated using the Queuing theory. In this Load Balancing system, the SSL based load distribution schemes has been introduced for better performance. Read More Read Less

Abstract In this paper a new criterion for clusters validation is proposed. This new cluster validation criterion is used to approximate the goodness of a cluster.

This new cluster validation criterion is used to approximate the goodness of a cluster. The clusters which satisfy a threshold of the proposed measure are selected to participate in clustering ensemble. To combine the chosen clusters, some methods are employed as aggregators. Employing this new cluster validation criterion, the obtained ensemble is evaluated on some well-known and standard datasets. The empirical studies show promising results for the ensemble obtained using the proposed criterion comparing with the ensemble obtained using the standard clusters validation criterion. Besides to reach the best results, the method gives an algorithm based on which one can find how to select the best subset of clusters from a pool of clusters. Read More Read Less

Abstract This paper proposes a new speech steganography system for secure sound massages sharing. This system exploits the advancements in speech processing to hide efficiently secret speech in narrowband cover speech. Linear predictive coding is used to represent the secret speech with reduced number of parameters. These parameters are embedded in selective perceptually-irrelevant frequency locations of the cover speech. Objective and... This paper proposes a new speech steganography system for secure sound massages sharing. This system exploits the advancements in speech processing to hide efficiently secret speech in narrowband cover speech. Linear predictive coding is used to represent the secret speech with reduced number of parameters. These parameters are embedded in selective perceptually-irrelevant frequency locations of the cover speech. Objective and subjective measures show that the resulting stego speech, which contains the secret message, is indistinguishable from the cover speech. Read More Read Less

Medical image processing is a very significant area of research as it has far reaching impact in health system. For pattern recognition, the Support vector machine is applied increasingly. The parameters selection plays a significant role in support vector machine(SVM). Through this research we have introduced a better scalable parameter optimization method based on traditional PSO optimizing algorithm by changing the fitness function in the traditional process. We have experimented it in real life and we came out with promising results which reflected in the ROC curves in medical images classification. Read More Read Less
