Abundance of the onuphids polychaete Onuphis eremita in Tranquebar, Southeast coast of India
Veeramuthu Sekar,Ramadoss Rajasekaran,Oliva J. Fernando
Advances in Environmental Sciences , 2012,
Abstract: The results of the present study describe observations about the distribution of the intertidal polychaete Onuphis eremita along sandyshore of Tranquebar coast, southeast India. The samplings were collected from three different water levels during one year. In sandy shores thebeach worms were crowded. The tidal exposure and percentage composition of sediment particles and organic matter were the main factors influencingthe animal abundance. Highest density was 15.66/m2 in low water mark (LWM) in summer and lowest density occurred during monsoon(4/m2) at high water mark (HWM). The larger animals (32.6 cm) were collected at low water mark and smallest animals (9.2 cm) at midwater mark levels. The environmental parameters showed significant variation with respect to the polychaete distribution. In general the lowwater mark level harbored a larger range of size and number of individuals than the mid water mark and high water mark levels. In addition,these worms had got importance in this region due to their use as bait for more common edible fishes like Sea boss, Groupers, Siver Sillago,Snappers, Rabbitfish and other smaller carangids.
The Impact of Firm Size on Dividend Behaviour: A Study With Reference to Corporate Firms across Industries in India

Managing Global Transitions , 2010,
Abstract: The objective of this paper is to examine the association between the Corporate Leverage (CL) and the Dividend Policy (DP) of firms across industries in India in respect of Size of Corporate Firms. The investigation is conducted on a panel sample of 73 firms across industries [Cement, Chemical and Fertilizer, IT, Oil and Gas, Pharmaceutical, Shipping, and Textiles], which listed their shares in National Stock Exchange (NSE) in India for the period 1996–2007. The impacts of Capital Structure (CS) variables (leverage) on DP measures – dividend payout (Net dividend paid/net income) in the presence of some basic fundamental variables are considered to be the determinants of DP, using the Multiple Regression Technique (OLS method). The results of the cross-sectional ols Model for the selected sample firms under various sectors show that there is a significant effect of selected independent variables. Therefore, this study proves that the DP of Small Size, Medium Size, Large Size, and Overall Corporate Firms across industries in India is dependent on the level of debt in CS.
smart application for AMS using Face Recognition
MuthuKalyani. K,VeeraMuthu. A
Computer Science , 2013,
Abstract: Attendance Management System (AMS) can be made into smarter way by using face recognition technique, where we use a CCTV camera to be fixed at the entry point of a classroom, which automatically captures the image of the person and checks the observed image with the face database using android enhanced smart phone. It is typically used for two purposes. Firstly, marking attendance for student by comparing the face images produced recently and secondly, recognition of human who are strange to the environment i.e. an unauthorized person For verification of image, a newly emerging trend 3D Face Recognition is used which claims to provide more accuracy in matching the image databases and has an ability to recognize a subject at different view angles.
Invasive Alien Plants of Indian Himalayan Region—Diversity and Implication  [PDF]

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.32021
Abstract: The present study deals with comprehensive list of Invasive alien plants of Indian Himalayan Region with background information on family, habit and nativity. A total of 190 invasive alien species under 112 genera, belonging to 47 families have been recorded. Among these, the dicotyledons represent by 40 families, 95 genera and 170 species; monocotyledons represent by 7 families, 17 genera and 20 species. The analysis of invasive species reveals that 18 species have been introduced intentionally, while the remaining species established unintentionally through trade. In terms of nativity, amongst 13 geographic regions, the majority of invasive plants reported from American continent (73%). While in life form analysis, the herbs (148 species) are dominant, followed by shrubs (19 species), Grass (11 species), Trees (4 species), sedges and climber (3 species each). Most of the invasive species are annual habit (63%). Apart from these, 90 species (47%) are being used by locals for medicinal purposes. A better planning is needed for early detection to control and reporting of infestations of spread of new and naturalized weeds to be monitored.
Role of Strontium on the Crystallization of Calcium Hydrogen Phosphate Dihydrate (CHPD)  [PDF]
K. Suguna, C. Sekar
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.107048
Abstract: Calcium hydrogen phosphate dihydrate (CHPD, CaHPO4· 2H2O) or brushite is found quite frequently in urinary calculi (stones). Crystallization of brushite has been carried out in sodium metasilicate (SMS) gel with and without adding ‘Sr’ as additive. In pure system, dicalcium phosphate anhydrous (DCPA, CaHPO4) or monetite and hydroxyapatite (HA, Ca5(PO4)3(OH)) grew along with brushite. The presence of Sr suppressed the formation of HA and enhanced the number and size of monetite crystals and changed the morphology of brushite crystals from needle shape to octopus-like shape. The samples were characterized by powder & single crystal X-ray diffraction (XRD), scanning electron microscopy (SEM), Xray fluorescence spectroscopy (XRF), Fourier transform infrared spectroscopy (FTIR) and thermal analyses (TG-DTA).
Effect of Magnesium on the Mechanical and Bioactive Properties of Biphasic Calcium Phosphate  [PDF]

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2012, DOI: 10.4236/jmmce.2012.1110099
Abstract: Incorporation of trace elements into calcium phosphate structure is of great interest for the development of artificial bone implants. Biphasic calcium phosphate (BCP) composed of hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) have been synthesized in the presence of magnesium (5 M% - 20 M%) by gel method under physiological conditions. Crystallization of Mg-BCP in the gel medium mimics the Mg intake in the human body. Powder X-ray dif- fraction and Fourier transform infrared analyses confirmed that the Mg doping leads to the enrichment of β-TCP phase and suppresses the HA content in BCP. Nanoindentation studies indicate a significant decrease in hardness and elastic modulus values of BCP due to Mg doping. In vitro bioactivity study has confirmed the formation of apatite layer on the Mg doped samples making it suitable for bone replacement. The results suggest that the optimum Mg doping promotes the bioactivity which is perquisite for biomedical applications.
Analysis of linear and nonlinear stiff problems using the RK-Butcher algorithm
S. Sekar
Mathematical Problems in Engineering , 2006, DOI: 10.1155/mpe/2006/39246
Abstract: I present a numerical solution of linear and nonlinear stiff problems using the RK-Butcher algorithm. The obtained discrete solutions using the RK-Butcher algorithm are found to be very accurate and are compared with the exact solutions of the linear and nonlinear stiff problems and also with the Runge-Kutta method based on arithmetic mean (RKAM). A topic of stability for the RK-Butcher algorithm is discussed in detail. Error graphs for discrete and exact solutions are presented in a graphical form to show the efficiency of the RK-Butcher algorithm. The results obtained show that RK-Butcher algorithm is more useful for solving linear and nonlinear stiff problems and the solution can be obtained for any length of time.

Guna Sekar
Journal of Global Research in Computer Science , 2012,
Abstract: This paper describes a portfolio optimization system by using Neuro-Fuzzy framework in order to manage stock portfolio. It is great importance to stock investors and applied researchers. The proposed portfolio optimization approach Neuro-Fuzzy System reasoning in order to make a more yields from the stock portfolio, and hence maximize return and minimize risk of a stock portfolio through diversification and right investment allocation to the particular stock under uncertainty. To evaluate the performance of forecasting and optimization system, BSE Sensex index of India considered as benchmarks in this study to measure efficient forecasting models. The results show that the proposed Neuro Fuzzy system produces much higher accuracy when compared to other portfolio models.
