A Review on IELTS Writing Test, Its Test Results and Inter Rater Reliability
Veeramuthu a/l Veerappan,Tajularipin Sulaiman
Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.2.1.138-143
Abstract: This research paper is based on the Academic Modules of IELTS test. A study is conducted to evaluate the performance of IELTS test takers and to analyze inter rater reliability in evaluating the test. The test is held at a private university and there are 9 participants who are the students of Foundation, Diploma and Degree courses were assessed only on writing component. This test is rated by three different raters to observe inter rater reliability in evaluating the test. The findings show that rating is not reliable and there is less agreement between the raters as different raters awarded different marks for the students. The total accumulated marks are 588 out of maximum 900 marks and the average score of these 9 students are 65.3% and falls under band 6. Since the IELTS test uses holistic marking, the raters find that the scoring rubrics are too vague in defining the qualities of writing. This study proposes analytic scoring system as a better procedure in assessing IELTS test, whereby it uses separate scales to assess different aspects of writing rather than a single score. The inter rater reliability issue can be overcome if test providers are able to furnish grading scales that could clearly equate the total marks achieved by a candidate to an appropriate band. The result and discussion from this study cannot be generalized to all IELTS candidates as there are many limitations in this study such as student preparedness, tester marking experience, time constraint, and reliability of the test and the validity of the marks tabulation method.
The Effect of Scaffolding Technique in Journal Writing among the Second Language Learners
Veeramuthu A/L Veerappan,Wei Hui Suan,Tajularipin Sulaiman
Journal of Language Teaching and Research , 2011, DOI: 10.4304/jltr.2.4.934-940
Abstract: It was noted that one of the most distressing challenges faced by the L2 college students was the poor presentation of their journal writing skills. The researcher noticed a prevailing pattern in their journal writing, where most of them were unable to construct proper sentences, making too many grammatical errors and also lacking in vocabulary. These factors have eventually restricted them from expressing their ideas clearly and effectively in their journal writing. Therefore, this study is primarily designed to look at how second language learners have acquired the use of English language through journal writing and how they have improved within a short time frame. The researcher scaffold a number of 3 undergraduate university college students by using several interactive writing techniques and instructions in writing a journal which showed their progress, daily activities and new experiences. The writing errors from the samples of written journals during week 1 were as it was written before and during the scaffolding period. Data were collected and the results of the progression were obtained based on the observation and comparison of written journals on week 1 and 5. The scaffolding technique presented in this study has helped remedy the challenges faced by the target students by further developing their effectiveness in journal writing.

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.
Analysis for flexibility in the ovality and thinning limits of pipe bends
A. R. Veerappan,S. Shanmugam
Journal of Engineering and Applied Sciences , 2008,
Abstract: Pipe bends are critical components in piping systems. In the manufacturing process of pipe bends it is difficult to avoid thickening on the intrados and thinning on the extrados. The cross section of the bend also becomes non circular due to bending process. The acceptability of pipe bends is based on the induced level of these shape imperfections. Ovality and thinning are the shape imperfections considered for the analysis. It is observed that thinning and ovality are to be taken into account together to decide the acceptability of these bends. The possible flexibility that can be introduced in the selection of ovality and thinning limits of pipe bends to reduce rejection has been suggested. A general mathematical expression relating internal pressure, shape imperfections and bend geometry is also presented.
Design and Analysis of Low Power Hybrid Memristor-CMOS Based Distinct Binary Logic Nonvolatile SRAM Cell  [PDF]
Veerappan Saminathan, Kuppusamy Paramasivam
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.73012
Abstract: Memristor is a newly found fourth circuit element for the next generation emerging nonvolatile memory technology. In this paper, design of new type of nonvolatile static random access memory cell is proposed by using a combination of memristor and complemented metal oxide semiconductor. Biolek memristor model and CMOS 180 nm technology are used to form a single cell. By introducing distinct binary logic to avoid safety margin is left for each binary logic output and enables better read/write data integrity. The total power consumption reduces from 0.407 mw (milli-watt) to 0.127 mw which is less than existing memristor based memory cell of the same CMOS technology. Read and write time is also significantly reduced. However, write time is higher than conventional 6T SRAM cell and can be reduced by increasing motion of electron in the memristor. The change of the memristor state is shown by applying piecewise linear input voltage.

Kishore Kumar Hotha, Swapan Roychowdhury, Veerappan Subramanian
American Journal of Analytical Chemistry (AJAC) , 2016, DOI: 10.4236/ajac.2016.71011
Abstract: The objective of the current research article is to provide a comprehensive review of excipients impact on the stability of the drug product and their implications during the product development. Recent developments in the understanding of the degradation pathways further impact methodologies used in the pharmaceutical industry for potential stability assessment. The formation of drug excipient adducts was very common based on the sensitive chemical moieties in the drugs and the excipients. The formation of the impurities was not limited to drug related impurities but there were several possibilities of the drug-excipient adduct formations as well as excipient impurities reaction with Active Pharmaceutical Ingredients. Identification of drug degradation in presence of excipients/excipient impurities requires extensive knowledge and adequate analytical characterization data. Systematic literature review and understanding about the drug formulation process, give you a smooth platform in establishing the finished product in the drug market. This paper discusses mechanistic basis of known drug-excipient interactions with case studies and provides an overview of common underlying themes in solid, semisolid and parenteral dosage forms.
Drug-Excipient Interaction of Methylphenidate with Glycerin in Methylphenidate Oral Solution and Identification of its Transesterification Products by UPLC-MS/MS  [PDF]
Kishore Kumar Hotha, Swapan Roychowdhury, Veerappan Subramanian
American Journal of Analytical Chemistry (AJAC) , 2016, DOI: 10.4236/ajac.2016.72013
Abstract: Reactions between active drug substances and excipients are of interest in the drug formulation process should be checked for the interactions during the storage conditions. Some excipients react with certain chemical groups in drug substances which will form new impurities in the finished product formulations. In the present paper transesterification reaction of methylphenidate with glycerin to form different structural isomeric products was described. These impurities identified in forced degradation studies, excipient compatibility studies and stability analysis of the finished product. Stability samples were analyzed and observed that about ~0.6% of the Methylphenidate content was transformed into methylphenidate-glycerin isomers within 3 Months at 40°C/75% RH and 18 Months at 25°C/60% RH conditions. Analysis of two lots of marketed preparations having expiry dates in 2012 and 2013 showed content of the Methylphenidate esters corresponding to ~0.6% of the declared Methylphenidate content. The samples of this impurity were investigated by HPLC, UPLC-MS/MS to generate the mechanism of the impurity formation.

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.
Correlation between pipe bend geometry and allowable pressure in pipe bends using artificial neural network
AR Veerappan, S Shanmugam
International Journal of Engineering, Science and Technology , 2011,
Abstract: Determination of allowable pressure, which is one of the important criteria to evaluate the acceptability of pipe bends with shape irregularities, is complex as the analytical solution of the problem involves solution of complex differential equations. Artificial Neural Network (ANN) is used in this paper to determine the allowable pressure ratio for pipe bends with varied range of ovality and thinning/thickening, pipe ratio and bend ratio. A set of numerical data of pipe bends with shape irregularities obtained from ANSYS analysis is used in ANN to obtain a mathematical relationship between various design parameters of pipe bends namely pipe diameter, wall thickness, bend radius, ovality, thinning/thickening and the internal pressure load. The ANN result is in close agreement with the numerical output obtained from ANSYS.
