Abstract: Clustering of proteins is important in the field of bioinformatics. Clustering of proteins is used for analyzing the proteins to determine their functions and structure. The number of partitioning techniques, hierarchical methods and graph-based methods are available for clustering protein sequences. In this paper, we propose a hybrid fuzzy technique for clustering proteins based on its secondary structure elements. The algorithm works in two stages. In the first stage, initial number of clusters is determined using k-nearest neighbor distances. The second stage comprises membership calculation and cluster construction. The performance of the hybrid fuzzy clustering was evaluated by comparison with other existing methods on four data sets. Experimental results show that proposed approach performs better in terms of validity indices and execution time as well.

Abstract: Informal software engineering methods have been using combination of diagrams, text, tables and simple notation to create analysis and design models with application of little mathematical rigour. On the other hand, formal methods allow a software engineer to create a model that is more complete, consistent, and unambiguous than those produced using conventional methods (Roger, 2005). However, it had been observed that the fundamental step in the Markov analysis of a software specification is to define the underlying probability law for the usage of the software under consideration. From an analytical point of view, this is a traceable stochastic process and a good basis for statistical testing...........

Abstract: The crucialrule of Grid systems is intentional resource sharing among individual Grid users.However; there is an intrinsicfriction between individual prudence and collective welfare that threatens the viability of these systems. Grid systems have emerged as a popular alternative to traditional client-server architectures for resourcesdistribution and sharing. Different academic studies have observed high levels of free-riding in various Grid systems, leading some to suggest the imminent collapse of these systems as viable resource sharing mechanism. This observable fact was due to hidden-action, hidden information as well as betrayer of co-operation and confidence among the selfish participating users with diverse malicious intentions. In Grid system, the supply and demand theory.............

Abstract: Every day, a large volume of data is generated by multiple sources, social networks, mobile devices, etc. This variety of data sources produce a heterogeneous data, which are engendered in high frequency. One of the techniques allowing to a better use and exploit this kind of complex data is clustering. Finding a compromise between performance and speed response time present a major challenge to classify this data. This paper aims to propose efficient Distributed clustering algorithms to handle big data with MapReduce which is an improved version of single machine clustering.

Abstract: Storing and monitoring Big data in widely distributed environments for 24/7 is a huge task for global service organizations. These datasets require high processing power which can't be offered by traditional databases as they are stored in an unstructured format. Apache Hadoop is open source software for reliable, scalable and distributed computing. This framework is inspired by Google's MapReduce structure in which application is broken down into numerous small parts and each part can be run in any node in the cluster. This paper contains detailed study of the execution of MapReduce programs over Hadoop cluster .It also discusses how the Hadoop platform offers an easy way of distributed Bigdata computing.

Abstract: Big data is key force of modernization diagonally in both educational as well as business. In the Cloud computing, big data security is a current and critical research topic. Cloud computing plus data storage offers clients among different facilities to accumulate as well as run their big data in third party data handling hubs. When a corporation selects to accumulate data or applications on the open cloud, it drops its capacity to have substantial access to the servers crowding its data. As a consequence, probably hypersensitive data is at risk from aids offensives. This difficulty turns into a concern to firm when considering uploading data on to the cloud. In this paper, we have proposed a new method that facilitates capable access control through dynamic policy that updating for big data in the cloud system...............

Abstract: This paper present a new bit redundancy coding for image compression in binary bit planar coding. In the compression model, images are coded into binary level to stream over a communication medium or to store the processed data in a remote location. In this processing, the representative coefficients are coded in binary level and to minimize the resource overhead these bits are compressed using binary compression logic. Among different coding logic, Huffman coding is the standard coding approach, standardized by JPEG and JPEG-2K image compression committee. The coding schemes computes a bit pattern occurrence probability and derive a allocating code word for a pattern...............

Abstract: Face recognition has drawn dramatic attention due to the advancement of pattern recognition technologies. Face recognition systems have reached a level of maturity under certain conditions but still the performance of face recognition algorithms are easily affected by external and internal variations. Thus many well-known algorithms have been proposed to overcome these challenging problems. Here we are trying to use one sample face image of individual for training the whole system which will not only reduce labouring effort for the collection and also reduce cost for storing and processing them. One sample per person face recognition (OSPP) is considered as a challenging problem in face recognition community and lack of samples leads to performance deterioration. Here face recognition is performed by application of the swarm optimization algorithms[12]............

Abstract: The IEEE 802.15.4 standard along with ZIGBEE specifications is used as communication standard for minimum power consumption, inexpensive networks such as LR-WPAN. The networks have different topologies depending on its applications such as Peer-to-Peer, Cluster tree, Mesh and STAR topology. In IEEE 802.15.4 standard for MAC layer , there are two modes of operations which are non-beacon mode and beacon mode. In beacon mode, PAN coordinators will send beacon signals to synchronize with their respective nodes, manage the network and the power of the transmitting systems and also perform the time synchronization of the data. Thus, if there are more than one PAN coordinators

Abstract: Data security has become a growing concern in this digital age. Current cryptographic algorithms either compromise on computational speed or data security. We put forth a variable key length 1024-bit symmetric cryptosystem which encrypts and decrypts text data in the form of 256-bit blocks at a time. It is fast as well secure and it is completely dependent on the key.
