R.K. Sharma

Abstract-Ba-doped PLZT ceramic compositions with the chemical formula Pb0.9(La1_zBaz)0.1Zr0.65Ti0.35)0.975O3 in which z=0, 0.02, 0.04 and 0.06 were prepared using a mixed oxide method. Grain size and apparent density decreased with increasing acceptor (Ba) content in the PLZT system. The optimum dielectric properties (εRT, εTc and tanδ) were observed in PLZT and decreased with Ba substitution. Ba substitution in the PLZT system influenced the ferroelectric remnant polarization (Pr) and spontaneous (Ps) polarization, both the coercive field (Ec) and remnant polarization (Pr) decreased in Ba-doped PLZT composition.

2 Reduction of area and delay in Binary comparator
V.Joel Ebenezer, G.Nandhakumar

Abstract— Reduction of Gates in a comparator helps in the reduction of area and also indirectly reduces the delay of the comparator. In general two types of gates are used in the designing of comparators. The concept of majority gates which was introduced in prior existing technique helped in the reduction of gates. This was implemented in Quantum-dot cellular automata (QCA). QCA is a coplanar structural nanotechnology tool which has many disadvantages. Majority gate concept is being implemented in Xilinx and the count of Gates was reduced to 69 from 83 for a 32 bit comparator.

3 Multi-hop Stable Selection with Mobile Sink in Wireless Sensor Network
Sahil kapoor, Anil Sagar, Mohit Marwaha

Abstract—Wireless sensor networks are remote networks and works in ad-hoc manner. Sensors collect the information sensed by them and send it to cluster head. All such cluster heads pass on the information to the sink where it is further compiled and processed as per the need of the underlying application .In our research, we will propose a cluster based novel multihop stable election protocol extended which does multihop communication between CHs and sensor nodes towards the sink. Multihop communication is used to form cluster head communication with other sensor nodes and concept is based on nearest sink available. If sink is available nearer than cluster head then data will sent to sink and if cluster head is present nearer more than sink then communication will be done with cluster head. Mobile sinks will be configured manually according to the density of the nodes available for sensing purposes. For example we can place number of mobile sinks for two clusters which includes 15 nodes each. Cluster heads will based on routing protocol will send the information to the nearest mobile heads available. Further in future, mobile sinks can be used for authentication processes also.

Mohit Marwaha, Amit Verma

Abstract—The Cloud computing is blend of conventional computing technology and network technology like grid computing distributed computing, parallel computing, web hosting and so on. It tries to develop a powerful computing platform at relatively low cost by using the advanced business models like SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service) to hand out the powerful computing capability to the user. Cloud computing provides a new model for IT service delivery and it typically involves over-a-network, on-demand, self-service access, which is dynamically scalable and elastic, utilizing pools of often virtualized resources making cloud computing the next big thing after internet. But question Questions about cloud data protection, data privacy and other Security issues may continue to linger and are cited as the most substantial roadblock for cloud computing uptake. We are trying to develop an encryption based system to contour these problems [17].

10 Secured Connectivity of Optimal Increase in Multi-hop Wireless Ad Hoc Networks
Subashini.S, Praveen Kumar.S

Abstract—We reflect on the trouble of how to increase secured connections after deployment of multi-hop wireless ad hoc networks. Two advance features, based on graph extension troubles with nonlinear edge costs, are evaluated. The Initial way is based on launching a secret key using only secret keys that are secured for the links. This type of problem is in NP-hard and does not accept polynomial time approximation scheme PTAS since minimum cut sets to be extended which do not admit constant costs. The next way is to connect between a pair of nodes in a mode of increasing the power level between them physically. This problem can be evaluated as the optimal key beginning problem with interference constraints with biobjectives: (i) increasing the coexisting key establishment flow, (ii) lowering the cost of intermediate nodes. We show that both problems are NP-hard and MAX-SNP (i.e., it is NP-hard to approximate them within a factor of 1 + ² for ² > 0) with a reduction to MAX3SAT problem. Thus, we intend and employ a fully distributed algorithm for authenticated key establishment in wireless sensor networks where each sensor knows only the neighborhood hop node. Our witness based approaches find witnesses in multi-hop two neighborhood nodes to authenticate the key establishment between them which do not share a key and which are not joined through a secured path.

14 3d Image Cropping For Various Displays
Anand.J, Hemalatha.P, Amsavalli.K, Rajini Girinath.D

Abstract—Stereoscopic photos should be carefully adapted to view effectively on the displays other than originally intended. Existing image manipulation techniques, such as cropping works well for images containing a single important object, and down sampling works well for images containing low frequency information. However, when these techniques are automatically applied to images with multiple objects, the image quality degrades and important information may be lost. Our algorithm addresses the case of multiple important objects in an image. The retargeting algorithm segments an image into regions, identifies important regions, removes them, fills the resulting gaps, resizes the remaining image, and re-inserts the important regions. Our approach lies in constructing a topologically constrained epitome of an image based on a visual attention model that is both comprehensible and size varying, making the method suitable for display-critical applications. Our experiments on a wide variety of stereoscopic photos demonstrate that our method can robustly produce display dependent stereoscopic photos that deliver pleasant viewing experiences.

16 An Approach to Improve the Throughput OF ZigBee Cluster Tree Network
Trupti Satavse, Vijayalaxmi Kadrolli

Abstract—ZigBee is a unique communication standard that is mainly used for short distance communication applications. It supports three topologies namely-Star, Mesh and Cluster Tree. Among which cluster tree is widely used; because it can support power saving operations and lightweight routing. However rigid routing and poor bandwidth utilization, this topology lacks the capability to handle increased traffic load. In such case it becomes mandatory to introduce new framework for ZigBee cluster tree network. In this paper we suggest to use an Adoptive Parent Based Framework along with Distributed Algorithm-PPR that will help to utilize bandwidth effectively and improve the throughput.

17 PB FCFS Algorithm for Scheduling and Backfilling in Grid Computing
G G Girija vasumathi

Abstract—Grid computing is combination of coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations. It is used to aggregate the power of widely distributed resources, and provide non-trivial services to users. To achieve this goal, an efficient Grid scheduling system is fundamentally important. Many of the existing tasks scheduling algorithms are commonly used for reservation, backfilling. Due to these algorithms insufficiency, the system resource utilization rate and the response time will be decreased significantly. In order to improve the system resource utilization rate and reduce the response time, a new task scheduling Priority Backfilling First Come First Serve (PB-FCFS) algorithm has been proposed. This algorithm combines backfilling, FCFS scheduling and adopts the dynamic priority strategy in task scheduling. The simulation results show that the PB-FCFS algorithm reduces the task run time and improves the system throughput and resource utilization rate.

18 Mammogram calcification classifications based on wavelet transform
K.C.Aarthi, A.Rajeswari

Abstract—Cancer affects people globally with breast cancer being a leading killer. Breast cancer is due to the uncontrollable multiplication of cells resulting in a tumour or neoplasm. Tumours are called ‘benign’ when cancerous cells do not ravage other body tissues and ‘malignant’ if they do so. As mammography is an effective breast cancer detection tool at an early stage which is the most treatable stage it is the primary imaging modality for screening and diagnosis of this cancer type. Due to the significance of an automated image categorization to help physicians and radiologists, much research in the field of medical images classification has been done recently. This paper presents an automatic mammogram classification technique and classifies it into normal and abnormal.

Abstract—Now a day’s networking plays a very important role in each and every human life. As the network is gaining its popularity in usage by various users, the major problem that was faced by network user is the ability to control the defects that was caused by network during communication. Now a day’s administrators mainly rely on rudimentary tools like Ping, Trace route for debugging the network problems. As the current procedures are always manual it is very difficult for each and every user to trace route errors at all times. So in this paper we have implemented an Automated Test Packet Generation where each and every packets will be tested before it is been transferred to the destination node. By conducting various experiments, our simulation result clearly tells that ATPG is the tool which was designed for the first time in order to balance the network problems.
