Reworking the Antonsen-Bormann idea

The Antonsen - Bormann idea was originally proposed by these authors for the computation of the heat kernel in curved space; it was also used by the author recently with the same objective but for the Lagrangian density for a real massive scalar field in 2 + 1 dimensional curved space. It is now reworked here with a different purpose - namely, to determine the zeta function for the said model using the Schwinger operator expansion.Comment: To appear in Journal of Physics:Conference Series (2012

PLANT DISESASE DETECTION BY USING IMAGE PROCESSING TECHNIQUES

In agriculture research of automatic leaf disease detection is an essential research topic as it may prove benefits in monitoring large fields of crops, and thus automatically detects symptoms of the disease as soon as they appear on plant leaves. The term disease is usually used only for the destruction of live plants. This paper provides various methods used to study of leaf disease detection using image processing. The methods studies are for increasing throughput and reduction subjects arising from human experts in detecting the leaf disease [1].digital image processing is a technique used for enhancement of the image. To improve agricultural products automatic detection of symptoms is beneficial

Fuzzy enhanced Cluster based Energy Efficient Multicast Protocol for Increasing Network Lifetime in WSN

99–102Wireless Sensor Networks (CWSN) consists of sensor node which is mobile roaming inside and outside the network region. The difficulty in existing models observed is to identify the best routes for forwarding packets. If the balancing of packet arrivals and energy conservation is not achieved, it may lead to reduction of network lifetime. In our research work, Fuzzy enhanced Cluster based Energy Efficient Multicast Protocol (FCEEMP) is developed based on three aspects. First one, the establishment of multicast routing based on the calculation of best route metric and average reliability metric. Second, the cluster is formed based on node stability and route capability. Three set of nodes are formed in the cluster network model i.e. sensor node, cluster member and Cluster Head (CH) to estimate energy consumption. Third, enhancement of fuzzy model is implemented to produce optimal energy and the value of network lifetime. From the simulation analysis, proposed protocol achieves better improvement over existing schemes

Predication of Drug Target Interaction using Reliable Multicast Routing in Wireless Ad hoc Molecular Network

Wireless Ad hoc Molecular network consists of atoms in terms of nodes in the absence of administrative point. In this connection, there is a need to adopt molecular analogy to define the architecture. Prediction of Drug Target Interaction (DTI) is a major impact in molecular ad hoc network. Efforts were made to combine such information with data to define DTI and to construct biological space. The concept of Conditional Random Field (CRF) is used in our proposed reliable multicast routing to integrate genomic, chemical and functional data to predict DTI. Reliability of links was also maintained to increase the network performance. Based on the extensive simulation results, the proposed reliable routing protocol achieves better performance than existing schemes

Design and Development of Network Reliability based Secure Multicast Routing Protocol for MANET

In Mobile Ad hoc network (MANET), link quality and stability of links as well as nodes play a major role. In ad hoc network, links are often changing which could affect the node mobility and integrity of data packets. In this research work, Network Reliability based Secure Multicast Routing Protocol (NRSMRP) is proposed to achieve network reliability by means of creation of reliable multicast tree. This multicast tree is constructed based on link quality and reliability trust metric. In first phase, node categorization and reliability metric calculation are implemented with the help of link quality. In second phase, reliable multicast tree is formed based on parent node and child node. Parent node must have god capacity and signal strength to communicate with child node. In last phase, authentication based multicast routes are established based on the calculation of direct reputation of mobile nodes. From the results, proposed protocol achieves better performance than existing schemes

Simulation of TI-SEPIC Converter for BLDC Motor Drives

Power Factor Correction (PFC) is one of the research areas in the field of power electronics due to the enormous power required in various industrial applications. In this work, a SEPIC converter with the Tapped Inductor model which is operated in Discontinuous current Conduction Mode (TI-SEPIC- DCM) is proposed for a BLDC Drive. The proposed TI-SEPIC-DCM also improves the voltage gain with the help of voltage multiplier cell and charge pump circuit. It also helps in attaining the ZVS and ZCS, which results in higher switching frequency range and reduction in size reduction. Moreover, a third order harmonic reduction control loop is also proposed to attain a better third order harmonic elimination. The proposed work has been simulated using MATLAB simulink and the results are also validated
