One Hundred Scopus Citations to a Non-Scopus Indexed Article: A Case Study
Elango Bakthavachalam 한국과학기술정보연구원 2023 Journal of Information Science Theory and Practice Vol.11 No.4
Receiving 100 citations from indexed journals is not a common occurrence, although it does happen very rarely, and it is even more uncommon for a non-indexed article. Given this, the purpose of this present study is to perform a bibliometric analysis of 100 cited Scopus articles to a non-Scopus indexed article, using a case study of the article titled “Authorship trends and collaboration pattern in the marine sciences literature: A scientometric study” which was published by Elango and Rajendran in the International Journal of Information Dissemination and Technology in 2012. On October 15, 2022, the Scopus database was searched with the article title in the references field, and the resulting bibliographic data was exported as a comma-separated values file. The tools utilized for this analysis were ScientoPy, the Bibliometrix R Package, and VOSviewer. Based on the findings, most of the cited articles were published within the last three years, and international researchers have given more recognition compared to Indian researchers. The most popular topics were found to be bibliometrics, bibliometric analysis, and bibliometrix. The fact that all 100 cited articles were published across various subject disciplines used by Scopus to categorise sources demonstrates how well-established the citing article is within the scientific community.

Sensitising cancer cells and at the same time desensitizing normal cells is a double task in cancer management. Agents which can combat the debilitating side effects of cancer therapeutics and simultaneously synergize with anticancer agents in specifically targeting cancer cells are needed. Selenium, a proven anticarcinogen, gains due importance in terms of its efficacy to combat the side effects of cancer therapy. This study is a comparative analysis of the chemoprotective effects of selenium compounds, methyl selenol (generated from organic selenomethionine (5mmol/L ; METase 40U/L)) and sodium selenite (inorganic form)($30{\mu}M$) in peripheral blood human lymphocytes exposed to cisplatin and mitomycin. Biochemical alterations occurring in many cells during apoptosis include loss of plasma membrane phospholipid asymmetry, DNA fragmentation, and activation of caspase-3. The present study demonstrated that the selenium metabolite and selenite are efficient in protecting lymphocytes undergoing DNA damage and exerted their activity by reducing caspase 3 expression. Interestingly organic methylselenol (MeSe) was found to offer more protective effects compared to inorganic selenite (SeL), by reducing the induction of apoptosis by the cytotoxic agents. This suggests that MeSe and to a lesser extent selenite might have potential for assessment in clinical trials and could be considered as strong candidates in pharmacogenomics or in the nutriprotective arena.
Global Tribology Research Output (1998 - 2012): A Macro Level Scientometric Study
Elango, B.,Rajendran, P. Korea Institute of Science and Technology Informat 2015 Journal of Information Science Theory and Practice Vol.3 No.4
The aim of this study is to compare country output and citation impact as well as to assess the level of interdisciplinarity in the field of tribology research during the period 1998-2012, based on the SCOPUS database. Macro-level scientometric indicators such as growth rate, share of international collaborative papers, citation per paper, share of un-cited papers, and publication efficiency index were employed. Further, the Simpson Index of Diversity was used to measure the level of interdisciplinarity. The performance of top countries contributing more than 1000 papers during the study period was discussed. Contributions and share of continents and countries by income groups were examined. Further research contributions and citation impact of selected country groups were analyzed. This study reveals that high levels of interdisciplinarity exist in tribology research. Asia outperforms the other world regions and China contributes most of the papers (25%), while the United States receives most of the citations (22%).
Hardware Implementation of FFT/IFFT Algorithms Incorporating Effi cient Computational Elements
Konguvel Elango,Kannan Muniandi 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.4
Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) computations involve quite a large number of complex multiplications and complex additions. Optimizing the FFT processing elements in terms of complex multiplication reduces area and power consumption. In this paper, complex multipliers in the FFT processors are replaced by area and power effi cient approximate multipliers. Approximate arithmetic computation appears to be eff ective solution for the systems that exhibit an intrinsic error tolerance. The computational errors arising because of approximation can be considered as trade-off for the signifi cant gains in power and area. Approximate 8- and 16-bit multipliers are used in radix-2 butterfl y unit which is the crucial computational component in FFT/IFFT processing. The designed FFT/IFFT processing units are analyzed, synthesized and simulated in Altera Cyclone II EP2C35F672C6 Field Programmable Gate Array (FPGA) device. Experimental results show that the proposed 16-point FFT architecture incorporating approximate complex multiplier achieves an area and power effi ciency of 33.47% and 1.8% respectively compared to accurate 16-point FFT processor. The 8-point and 16-point Decimation In Time (DIT)—FFT incorporating approximate computational elements operate at a speed of 26.69 Gbps and 46.20 Gbps, respectively.
Experimental Investigations of Skin-Like Material and Computation of its Material Properties
Natarajan Elango,Ahmad Athif Mohd Faudzi,Azman Hassan,Muhammad Razif Muhammad Rusydi 한국정밀공학회 2014 International Journal of Precision Engineering and Vol. No.
In this research, an experimental investigation is carried out with pure silicone of five different grades and blended mixture of differentgrades of silicone at 1:1 volume fraction for the development of a skin-like soft material for robotic applications. The samples areprepared by compression molding and tensile testing was performed on dumb-bell shaped specimens as per ASTM D412 standardat crosshead speed of 250 mm/minute It is observed from the experiments that silicone grade 10 crosslinked with Luperox 101 yieldedthe tensile strength of 2.189 MPa which is closer to the human skin in forearm. It is also derived from the experiments that blendedmixtures revealed the lower tensile strength than pure silicone of the same grade. Fourier Transform Infrared Spectroscopy (FTIR)and Scanning Electron Microscope (SEM) studies were also done on samples to understand the dispersion of the compounds andmechanical damages in the developed soft material. Finally, the numerical simulation for Mooney-Rivlin, Ogden and Yeoh non-linearmaterial modes are carried out and non-linear material constants of Silicone grade 10 are computed and tabulated. The developedsoft material will be used in robotics for soft manipulation in future.
Studies on weldment performance of Ti/Al dissimilar sheet metal joints using laser beam welding
Kalaiselvan, K.,Elango, A.,Nagarajan, N.M.,Mathiazhagan, N.,Vignesh, Kannan Techno-Press 2018 Coupled systems mechanics Vol.7 No.5
Laser beam welding is more advantageous compared to conventional methods. Titanium/Aluminium dissimilar alloy thin sheet metals are difficult to weld due to large difference in melting point. The performance of the weldment depends upon interlayer formation and distribution of intermetallics. During welding, aluminium gets lost at the temperature below the melting point of titanium. Therefore, it is needed to improve a new metal joining techniques between these two alloys. The present work is carried for welding TI6AL4V and AA2024 alloy by using Nd:YAG Pulsed laser welding unit. The performance of the butt welded interlayer structures are discussed in detail using hardness test and SEM. Test results reveal that interlayer fracture is caused near aluminium side due to low strength at the weld joint.
