Filter and wrapper are the two methods used but here the authors have proposed a hybrid feature selection method to take advantage of both methods. The proposed method uses symmetrical uncertainty and genetic algorithms for selecting the optimal feature subset. This has been done so as to improve processing time by reducing the dimension of the data set without compromising the classification accuracy. This proposed hybrid algorithm is much faster and scales well to the data set in terms of selected features, classification accuracy and running time than most existing algorithms.

Network clustering deals with partitioning network into clusters based on some rules. Clustering guarantees limited resource utilization and network scalability. In this paper, we mainly focused on using mobile agents for collecting information about cluster members and cluster maintenance. Ensuring security of mobile agent is a difficult task. In this work, the authorization of mobile agent is achieved using session key or secret key shared between mobile agent owner and node. We applied a distributed private key generation scheme, which generates secret key of cluster members based on 'n' key shares. The session key is generated based on past frequent traffic pattern that exist between the nodes. The behavior of mobile agent with respect to various security issues such as replay attack, non repudiation, denial of service and unauthorized access was discussed. The performance of the proposed scheme is evaluated under presence of varying number of malicious nodes. According to the observed results, the proposed protocol guarantees high packet delivery ratio and low delay, compared to cluster based routing protocol.

It provides pay and use method for grasping the services by the clients. Data center is a sophisticated high definition server, which runs applications virtually in cloud computing. It moves the application, services, and data to a large data center. Data center provides more service level, which covers maximum of users. In order to find the overall load efficiency, the utilization service in data center is a definite task. Hence, we propose a novel method to find the efficiency of the data center in cloud computing. The goal is to optimize date center utilization in terms of three big factors—Bandwidth, Memory, and Central Processing Unit (CPU) cycle. We constructed a fuzzy expert system model to obtain maximum Data Center Load Efficiency (DCLE) in cloud computing environments. The advantage of the proposed system lies in DCLE computing.

In the proposed algorithm, the input image is subjected to image analysis to remove some of the portions purposefully. At the same time, edges are extracted from the input image and they are passed to the decoder in the compressed manner. The edges which are transmitted to decoder act as assistant information and they help inpainting process fill the missing regions at the decoder. Textural synthesis and a new shearlet inpainting scheme based on the theory ofp-Laplacian operator are proposed for image restoration at the decoder. Shearlets have been mathematically proven to represent distributed discontinuities such as edges better than traditional wavelets and are a suitable tool for edge characterization. This novel shearletp-Laplacian inpainting model can effectively reduce the staircase effect in Total Variation (TV) inpainting model whereas it can still keep edges as well as TV model. In th...

The goal is to provide optimal control with reduced calculus effort by comparing the solutions of the matrix Riccati differential equation (MRDE), obtained from well known traditional Runge-Kutta (RK) method and genetic programming method. To obtain the optimal control, the solution of MRDE is computed based on grammatical evolution. Accuracy of the solution of the GP approach to the problem is qualitatively better. An illustrative numerical example is presented for the proposed method.
