Research ArticleOpen accessIn the author namesSPATIAL AND MULTIVARIATE ANALYSIS OF TRACE ELEMENTS IN THE SURFACE WATER AND DEEP SEDIMENTS OF FRESH WATER AQUATIC ECOSYSTEMKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Kamesh Viswanathan Baskaran et al.The aim of this study was to assess the levels of various trace metals present in water and sediment of fresh water aquatic ecosystem during the post monsoon season. The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India using an … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 26 Mar 2014 · 7,604 accessesView PDFCite
Research ArticleOpen accessIn the author namesIn-Vivo Evaluation of Hexavalent Chromium Induced DNA Damage by Alkaline Comet Assay and Oxidative Stress in Catla catlaKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Jaya Krishna KuruvaIn the present study, the acute toxicity of Chromium in fingerlings of Catla catla, an Indian major carp, was evaluated with renewal bioassay method. In vivo studies were designed to assess the extent of Micronucleus Assay, Comet Assay under the exposure of common heavy-metal compounds, namely, Chromium Nitrate, using Catla catla (2n = 20), as a test model. The laboratory … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 15 Jan 2014 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the author namesIMPROVING THE PERFORMANCE AND REDUCING BIT ERROR RATE ON WIRELESS DEEP FADING ENVIRONMENT RECEIVERSK. Jayanthi, V. P. Arunachalam, C. VasanthanayakiOne of the major challenges in wireless communication system is increasing complexity and reducing performance in detecting the received digital information in indoor and outdoor Environments. Consequently to overcome this problem we analyze the delay performance of a multiuser with perfect channel state information transmitting data on deep fading environment. In this proposed system, the Wireless Deep Fading Environment (WDFE) … …Journal of Computer Science, Vol. 10, Issue 3 · 29 Nov 2013 · 7,103 accessesView PDFCite
Research ArticleOpen accessIn the author namesRETRIEVAL OF 24 HOUR AEROSOL OPTICAL DEPTHS FROM MIE LIDAR DATASiriluk Ruangrungrote, Pichet Limsuwan, Arunee IntasornTemporal Aerosol Optical Depths (AODs) of Phimai district, Nakhon Ratchasima province in Thailand were retrieved from measured Mie lidar data on 17-20 February 2005 using Fernald method. The ground-based station was selected for its high and diverse local agricultural activities contributed to the aerosol content which allows for various parameters such as concentration, size distribution and aerosol optical properties to … …Physics International, Vol. 4, Issue 2 · 4 Sep 2013 · 6,517 accessesView PDFCite
Research ArticleOpen accessIn the author namesContext Aware Middleware Model for Handling Vehicular Safety IssuesArunkumar Thangavelu, R. A.K. SaravanaguruProblem statement: This study proposed a mathematical model for the existing framework InVANET; context prediction and simulation for vehicle safety. Approach: Markov process was used to model context and predict the states with the help of transition probability matrix. The context parameters were collected from CarSim simulator and inferred using JENA and SPARQL. Results: The longitudinal speed and lateral offset … …Journal of Computer Science, Vol. 8, Issue 8 · 12 Jul 2012 · 7,105 accessesView PDFCite
Research ArticleOpen accessIn the author namesStudy on Survival of Chlamydia trachomatis in the Presence of Antichlamydial DrugsApurb Rashmi Bhengraj, Pragya Srivastava, Harsh Vardhan et al.Problem statement: Recurrent genital Chlamydia trachomatis infections due to treatment failures may results in complex sequelae leading to reproductive complexity and morbidity. It can be resulted by the heterotypic resistance with decreased drug susceptibility characteristic of the isolate. Studies are needed to understand the treatment failures and resistance characteristic of C. trachomatis. Hence, in vitro study was conducted on C. … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 20 Feb 2012 · 7,774 accessesView PDFCite
Research ArticleOpen accessIn the author namesDynamic Approach to Defend Against Distributed Denial of Service Attacks Using an Adaptive Spin Lock Rate Control MechanismR. Anurekha, K. Duraiswamy, A. Viswanathan et al.Problem statement: The last decade has seen many prominent Distributed Denial of Service (DDoS) attacks on high profile webservers. In this study, we deal with DDoS attacks by proposing a dynamic reactive defense system using an adaptive Spin Lock Rate control (D3SLR). D3SLR identifies malicious traffic flow towards a target system based on the volume of traffic flowing towards the … …Journal of Computer Science, Vol. 8, Issue 5 · 17 Feb 2012 · 7,066 accessesView PDFCite
Research ArticleOpen accessIn the author namesMachining Performance Study on Metal Matrix Composites-A Response Surface Methodology ApproachA. Srinivasan, R. M. Arunachalam, S. Ramesh, J. S. SenthilkumaarProblem statement: Metal Matrix Composites (MMC) have become a leading material among composite materials and in particular, particle reinforced aluminum MMCs have received considerable attention due to their excellent engineering properties. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement element-like Alumina (Al2O3). Approach: In this study, an attempt has been made … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 15 Feb 2012 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the author namesMining of Datasets with an Enhanced Apriori AlgorithmS. Nandagopal, V. P. Arunachalam, S. KarthikProblem statement: Classical association rules are mostly mining intra-transaction associations i.e., associations among items within the same transaction where the idea behind the transaction could be the items bought by the same customer on the same day. The goal of inter-transaction association rules is to represent the associations between various events found in different transactions. Approach: In this study, we … …Journal of Computer Science, Vol. 8, Issue 4 · 14 Feb 2012 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the author namesFlow Based AlgorithmT. Karpagam, V. J. Sudhakar, N. Arunsankar, M. DhanasekaranProblem statement: Network topology design problems find application in several real life scenario. Approach: Most designs in the past either optimize for a single criterion like shortest or cost minimization or maximum flow. Results: This study discussed about solving a multi objective network topology design problem for a realistic traffic model specifically in the pipeline transportation. Here flow based algorithm … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 22 Dec 2011 · 8,484 accessesView PDFCite
