More on *gα-closed sets and *gα-open sets in the digital plane
M. Vigneshwaran,R. Devi
Journal of Global Research in Mathematical Archives , 2013,
Abstract: Digital topology was first studied by the computer image analysis researcher Azriel Rosenfeld [12]. The concept of *gα-closed sets in a topological spaces was introduced by M. Vigneshwaran and R. Devi[14]. In this paper, we study the properties of *gα-closed and *gα-open sets in the digital plane (Z2, k2). Also proved that the family of all *gα-open sets of (Z2, k2), say *GαO(Z2, k2), forms an alternative topology of Z2. Also we derive the properties of *gα-closed and *gα-open sets in the digital plane via the singletons points. Keywords: *gα-closed sets, *gα-open sets,digital plane, digital topology

M. Vigneshwaran,R. Chandiramouli,B.G. Jeyaprakash,D. Balamurugan
Journal of Applied Sciences , 2012,
Abstract: Cadmium oxide is the very crucial material in the field of solar cells, optoelectronic devices, flat panel displays due to its high transparency and narrow band gap. In this study, Mg doped CdO thin films were prepared using the home made spray pyrolysis unit and its structural and electrical properties were studied. The XRD results show that the grain size decreases upon increasing the dopant concentration from its broadened peak. Atomic Force Microscopy (AFM) analysis indicates that the roughness of the surface decreases upon increasing Mg concentration. The activation energy, I-V characteristics were studied using Four probe method. The results were analyzed for three different concentration of Mg doped CdO films and are reported.

International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: Bridge vibration control is an important issue whose purpose is to extend the structural service life of bridges. Normally, the bridge is modeled as an elastic beam or plate subject to a moving vehicle. However, the moving truck on a bridge is a complicated problem that must still be researched. In this paper, wepropose a new method, to overcome the huge load in the bridge a load cell is used at the entry which will monitor the load continuously at both ends. To escape from the heavy water flow bridge vibrations alarm is used and it is connected with the water over flow sensor which will convert the heavy water flow signal into electrical signal and this electrical signal will make an alarm and close the gate of the bridge. When both the problem occurs at same time or at different time an alarm is generated and the bridges will automatically closed.
A Dynamic Approach for Anomaly Detection in AODV
P.VIGNESHWARAN,R. DHANASEKARAN
International Journal of Ad Hoc, Sensor & Ubiquitous Computing , 2012,
Abstract: Mobile ad hoc networks (MANETs) are relatively vulnerable to malicious network attacks, and therefore, security is a more significant issue than infrastructure-based wire-less networks. In MANETs, it is difficult to identify malicious hosts as the topology of the network dynamically changes. A malicious host can easily interrupt a route for which it is one of the forming nodes in the communication path. Since the topology of a MANET dynamically changes, the mere use of a static baseline profile is not efficient. We proposed a new anomaly-detection scheme based on a dynamic learning process that allows the training data to be updated at particular time intervals. Our dynamic learning process involves calculating the projection distances based on multidimensional statistics using weighted coefficients and a forgetting curve.
Effect of Gum arabic on distribution behavior of nanocellulose fillers in starch film
Nadanathangam Vigneshwaran,L. Ammayappan,Qingrong Huang
Applied Nanoscience , 2011, DOI: 10.1007/s13204-011-0020-5
Abstract: Uniform distribution of nanofillers in polymer matrix is posing a major challenge in exploiting the full potential of nanomaterials. Various fillers are being evaluated to improve the performance of biopolymer films like starch. In this work, nanocellulose is used as fillers to increase the performance characteristics of starch film. Due to high surface energy and hydrophilic nature of nanocellulose, they tend to aggregate during the film forming process. To circumvent this problem, Gum arabic (GA) was added to distribute the nanocellulose uniformly. GA helps in reduction of surface energy (as analyzed by contact angle) and thus facilitates the uniform distribution of nanocellulose (as demonstrated through polarized light microscopy). Nanocellulose as filler improved the tensile strength of starch film by 2.5 times while that of uniformly distributed nanocellulose by 3.5 times. Moreover, while nanocellulose as such could reduce the water vapor permeability of starch film by 1.4 times, uniformly distributed nanocellulose reduced it by 2 times proving the importance of GA. Starch film filled with nanocellulose and GA will be a 100% biopolymer-based system having potential demand in eco-friendly applications.

International Journal of Soft Computing & Engineering , 2013,
Abstract: In this paper, bitmask based compression of FPGA bit-streams has been implemented. Reconfiguration system uses bitstream compression to reduce bitstream size and memory requirement. It also improves communication bandwidth and thereby decreases reconfiguration time. The three major contributions of this paper are; i) Efficient bitmask selection technique that can create a large set of matching patterns; ii) Proposes a bitmask based compression using the bitmask and dictionary selection technique that can significantly reduce the memory requirement iii) Efficient combination of bitmask-based compression and Golomb coding of repetitive patterns.

Abstract: Nanocellulose is a new-age material derived from cellulosic biomass and has large specific surface area, high modulus and highly hydrophilic in nature. It comprises of two structural forms viz., nanofibrillated cellulose (NFC) and nanocrystalline cellulose (NCC). This review provides a critical overview of the recent methods of bio- and chemo-mechanical processes for production of nanocellulose, their energy requirements and their functional properties. More than a dozen of pilot plants/commercial plants are under operation mostly in the developed countries, trying to exploit the potential of nanocellulose as reinforcing agent in paper, films, concrete, rubber, polymer films and so on. The utilization of nanocellulose is restricted mainly due to initial investment involved, high production cost and lack of toxicological information. This review focuses on the current trend and exploration of energy efficient and environment-friendly mechanical methods using pretreatments (both chemical and biological), their feasibility in scaling up and the future scope for expansion of nanocellulose application in diverse fields without impacting the environment. In addition, a nanocellulose quality index is derived to act as a guide for application based screening of nanocellulose production protocols.

Adel Merabet,Raquel Keeble,Vigneshwaran Rajasekaran,Rachid Beguenane,Hussein Ibrahim,Jogendra S. Thongam
Applied Sciences , 2012, DOI: 10.3390/app2040801
Abstract: An automatic power management system, to monitor the distribution of power to a set of load banks, is presented in this paper. The required power is generated from a laboratory-size pitch-controlled wind turbine experimental workstation. The management system is a sequence of logic expressions, based on the generated power, a profile of the banks’ states provided by the supervisor and the banks’ priorities, to obtain an optimal behavior of the system and to ensure the load requirement. A modified PI pitch angle control is proposed to regulate the generated power for tracking the power reference in order to maintain a consistent brilliance of the load’s LEDs, to reduce the activity of the pitch actuator and to deal with fluctuation problems. Experimental results are provided to show the effectiveness of the proposed automatic power management system for load banks supplied by a pitch controlled wind turbine.

N. Sreelalitha,E.Vigneshwaran,G.Narayana,Y.Padmanabha Reddy
International Research Journal of Pharmacy , 2012,
Abstract: Pharmaceutical Care is a patient-centered, outcome-oriented pharmacy practice that requires the qualified pharmacist to work in concert with the patient and the patient's other healthcare providers to promote health, to prevent disease, and to assess, monitor, initiate, and modify medication use to assure that drug therapy regimens are safe and effective. The goal of Pharmaceutical Care is to optimize the patient's health-related quality of life and achieve positive clinical outcomes. Pharmaceutical care entails the work of addressing a patient's medication related needs. The involvement of the pharmacist in India in this regard has been somewhat restricted, contrary to trends in developed countries. Nowadays medicine options have multiplied manifold thus raising the complexity of therapies. Pharmacists have a unique role to play in evaluating these options and also medication errors which are most common in occurrence. The present article explained about the functions of pharmacist in pharmaceutical care and barriers towards pharmaceutical care.

Abstract: The large amounts of EST sequence data available from a single species of an organism as well as for several species within a genus provide an easy source of identification of intra- and interspecies single nucleotide polymorphisms (SNPs). In the case of model organisms, the data available are numerous, given the degree of redundancy in the deposited EST data. There are several available bioinformatics tools that can be used to mine this data; however, using them requires a certain level of expertise: the tools have to be used sequentially with accompanying format conversion and steps like clustering and assembly of sequences become time-intensive jobs even for moderately sized datasets. We report here a pipeline of open source software extended to run on multiple CPU architectures that can be used to mine large EST datasets for SNPs and identify restriction sites for assaying the SNPs so that cost-effective CAPS assays can be developed for SNP genotyping in genetics and breeding applications. At the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the pipeline has been implemented to run on a Paracel high-performance system consisting of four dual AMD Opteron processors running Linux with MPICH. The pipeline can be accessed through user-friendly web interfaces at http://hpc.icrisat.cgiar.org/PBSWeb and is available on request for academic use. We have validated the developed pipeline by mining chickpea ESTs for interspecies SNPs, development of CAPS assays for SNP genotyping, and confirmation of restriction digestion pattern at the sequence level.
