Abstract

The Communication between objects in the cluster takes place through message passing techniques. Affinity Propagation (AP) clustering has been used successfully in a lot of clustering problems, which deals with static data. By applying Fuzzy DENCLUE, similarity between objects and its exemplar is improved. A dynamic variant of AP clustering called Incremental Affinity Propagation with K-Medoid (IAPKM) is used along with the Fuzzy Density based clustering (DENCLUE) method. In Fuzzy DENCLUE, number of clusters is reduced and randomness in the form of noise is removed. The experiment is performed in Net Beans 8.0.2 using jdk1.7 as a language. The evaluation result defines that the effectiveness and efficiency of IAPKM and Fuzzy DENCLUE can achieve comparable performance. Compared with IAPKM and Fuzzy DENCLUE, Sum of similarity and accuracy is increased in Fuzzy DENCLUE which is based on the parameters. The current approach achieves higher accuracy rate which is 10% greater than the former approach.

Abstract

Despite impressive gain in agricultural production and greater availability of food, a large population in India is suffering from nutritional imbalance. Improvements in total agricultural production leading to nutritive food would help combat under nutrition. To demonstrate the feasibility of agriculture- based remedy to malnutrition, five villages in Wardha district of Maharashtra were selected for validating the farming system for nutrition (FSN) approach.

On-farm demonstrations of arable crops and women-managed community nutrition gardens (CNGs) of vegetables and fruits were initiated. A wide choice of nutritive vegetables to be grown was promoted to reduce the off-farm transport cost and ensure higher availability of nutritive vegetables to the households. The additional nutritional gain through FSN can be quantified in terms of equivalence and can be calibrated to ensure that the households get the recommended daily intake of nutrition. Accordingly, a FSN approach is evolved to provide nutritional security to every house-hold.

Abstract

The application of Trichoderma viride on loose smut infected seeds (Ustilago segetum var. tritici) or in soil, reduced the smutted tillers up to 17.5 per cent. However, treatment of T. viride alone was not as effective as carboxin seed treatment in the control of loose smut. Maximum reduction was observed in dry seed treatment with antagonist as well as seed treatment plus soil application. The effect of T. viride was more prominent in the seed lot having lower level of loose smut infection. Application of T. viride along with half dose of carboxin was however. found as effective as full recommended dose of carboxin (2.5 g/kg of seed). Soaking of seeds in tap water for 24h also reduced tbe incidence of loose smut by 15.4 per cent.

Abstract

Loose smut of wheat (Triticum aestivum Lin.) caused by Ustilago segetum var. tritici is a major disease in north-western India. Loss caused by the disease varies from about 1 to 10 per cent (Joshi et al., 1985). The popular high yielding cultivars are genetically susceptible to the disease and treatment with systemic fungicides is the only means of disease control. Biological control of soil-borne diseases using toxin or antibiotic producing strains and those that are mycophagous have opened up potential areas for research (Cook, 1984). Therefore, an experiment was laid out using microbial antagonists to control the loose smut.

Abstract

A wireless sensor networks are made up of sensors which are usually energy constrained one. The lifetime of the network is directly proportional to the energy efficiency of these nodes and hence a lot interest has been focused to effectively prolong the longevity of the individual node and network lifetime. Several WSN protocols and clustering algorithms have been proposed on how to optimally select the cluster heads in the sensor networks. In this paper EECHP protocol is proposed by combining the Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) algorithm for enhancing the lifetime of wireless sensor networks. Experimental results show that the proposed approach EECHP protocol performs better than the ECHS, DECP and LEACH algorithms. A significant increase of network lifetime has been achieved and improved the First Node Death (FND) and Last Node Death (LND) respectively.

Abstract

As Cloud computing is gaining currency, the importance of securing and availing the stored data by the cloud service providers is becoming inevitably important.
Large amount of computing and services along with storage facility is provided by the CSPs. Unlike the normal traditional computing where the data was usually stored in one location, the data storage in Cloud is likely stored in several locations and is accessed through the high speed networks. In order to ensure security, we propose a novel way of improving the security of the stored data in cloud computing.
The proposal speaks of using Reed Solomon error correction codes for providing reliable data by maintaining redundant files in various locations. Also, we improve the verifiability by utilizing Halton sequence rather than pseudo random data, thereby filling the region avoiding large gaps that generally occur in pseudo random generator.

Abstract

Peer-to-peer file-sharing applications suffer from a fundamental problem of unfairness. Free-riders cause slower download times for others by contributing little or no upload bandwidth while consuming much download bandwidth. Previous attempts to address this fair bandwidth allocation problem suffer from slow peer discovery, inaccurate predictions of neighboring peers bandwidth allocations, underutilization of bandwidth, and complex parameter tuning. We present RF Torrent, a new deficit-based distributed algorithm that accurately rewards peers in accordance with their contribution. A RF Torrent peer simply uploads the next data block to a peer to whom it owes the most data as measured by a deficit counter. RF Torrent is resilient to exploitation by free-riders and strategic peers, is simple to implement, requires no bandwidth over allocation, no prediction of peers rates, no centralized control, and no parameter tuning.

Abstract

This paper deals with detection of broken bars in three phase squirrel cage induction motor using finite element model of the induction machine. Finite element method is more precise than the winding function approach, as it is based on the actual geometry of the machine. The machine model can easily be modified to study the effect of faults on the machine‟s performance. Accurate models of the machine under healthy and faulty conditions are developed. The static two-dimensional analysis is done for broken bar fault. The machine parameters like flux linkage, flux density and stored magnetic energy are obtained for healthy and faulty motor. The results examined under various conditions are compared and the observations are presented.

Abstract

Objective: The main objective of this research is to generate and provide an optimized itinerary planning for the users with flight and hotel booking as per the user requirement to reach their satisfaction level. Methods: In this research, a novel fuzzy c means clustering is introduced for grouping and generating an optimal itinerary planning for the group of users. This work intends to satisfy the needs of all the users who are requesting for the itinerary plans with the satisfaction of their QoS requirement. To achieve this goal, the point of interest (POI) graphs will be constructed with the help of mapRedcue application which will simplify the processing of large amount of data’s. FCM algorithm is proved to be better clustering algorithm which considers the membership values among the various data points. So that the same data points can be clustered in the different cluster to which its membership value belongs. In our work we make sue use of this algorithm to cluster the users with the similar requirements. So that the same user request may clustered in different groups. Among that the optimized cluster of users with unique requirements can be selected for the itinerary planning construction. Results: FCM clustering used in the proposed approach for effective construction of the itinerary planning with the consideration of the users with similar requirement whereas in the existing work user similarity requirements are not considered. The experimental tests conducted were proves that the proposed methodology provides the optimized itinerary with the less time complexity and burden than the existing methodology. This performance analysis is done with the two performance metrics namely processing time and the weight ratio from which it can be proved that the proposed methodology provides better result. Conclusion: The findings demonstrate that the itinerary planning construction using FCM is presented and this method has high clustering accuracy than the previous methodologies.

Abstract

This paper investigates the performance of Trans Z- source inverter (abbreviated as T ZSI) fed induction motor drive under various fault conditions. With development in power electronics and remarkable improvement in control techniques, induction motor has evolved as a variable speed machine. For critical applications, continuous operation of the drive is of paramount importance. However, their performance is restricted by electrical and mechanical faults. When any fault occurs, the phase and line voltages of the inverters get decreased. This leads to reduction of torque and speed of the motor and hence the operation of induction motor is interrupted. This states the importance for fault diagnosis of T Z-Source inverter fed induction motor to analyse the performance of the drive under faulty conditions. The performance of the induction motor under various faults is verified by MATLAB simulation of a 5 Hp induction motor fed by a high performance ZSI and the simulation results are presented. A comparative evaluation of Z-source and T Z-source topologies is done for the same load torque conditions.
