The McDonald Generalized Beta-Binomial Distribution: A New Binomial Mixture Distribution and Simulation Based Comparison with Its Nested Distributions in Handling Overdispersion
Chandrabose Manoj,Pushpa Wijekoon,Roshan Darshana Yapa
International Journal of Statistics and Probability , 2013, DOI: 10.5539/ijsp.v2n2p24
Abstract: The binomial outcome data are widely encountered in many real world applications. The Binomial distribution often fails to model the binomial outcomes since the variance of the observed binomial outcome data exceeds the nominal Binomial distribution variance, a phenomenon known as overdispersion. One way of handling overdispersion is modeling the success probability of the Binomial distribution using a continuous distribution defined on the standard unit interval. The resultant general class of univariate discrete distributions is known as the class of Binomial mixture distributions. The Beta-Binomial (BB) distribution is a prominent member of this class of distributions. The Kumaraswamy-Binomial (KB) distribution is another recent member of this class. In this paper we focus the emphasis on the McDonald's Generalized Beta distribution of the first kind as the mixing distribution and introduce a new Binomial mixture distribution called the McDonald Generalized Beta-Binomial distribution(McGBB). Some theoretical properties of McGBB are discussed. The parameters of the McGBB distribution are estimated via maximum likelihood estimation technique. A real world dataset is modeled by using the new McGBB mixture distribution, and it is shown that this model gives better fit than its nested models. Finally, an extended simulation study is presented to compare the McGBB distribution with its nested distributions in handling overdispersed binomial outcome data.
Empirical Modeling and Simulation of Temporal Based Adaptive Mobility Model for MANET  [PDF]
Gurusamy Prema, Chandrabose Aravindan, Kirthivasan Kannan, Rathinam Maheswaran
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.44028
Abstract: Mobile Ad Hoc network (MANET) is a collection of wireless mobile nodes forming a temporary network without the aid of any established infrastructure. To conduct meaningful performance analysis of MANETs, it is essential that the simulation of mobility model should reflect the realistic mobility pattern of mobile nodes i.e. placement of mobile nodes at different intervals of time. The formation of spontaneous network depends heavily on the movement of different nodes in a particular practical scenario. This research focuses on the modeling and simulation of a temporal Adaptive Mobility Model which can be adapted to any dynamic practical scenario. The mobility in the realistic environment is simulated based on a Probability Transition Matrix named as Personal Behavior Model (PBM) and validated for a practical Health Care Environment. The formation of MANET is assumed to be based on the movement of the patient i.e. mobile nodes in the health care environment. Patients waiting in front of each service point for different time intervals are taken as results and compared with the actual data.
Role of Infrared Spectroscopy in Coal Analysis—An Investigation  [PDF]
Manoj Balachandran
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.56044
Abstract: Fourier transform infrared (FT-IR) spectroscopy is a widely used analytical technique for determining the different functional groups of a coal structure. This method, being able to reveal carbo-hydrogenated structures (aromatic and aliphatic) and heteroatomic functions (mainly oxygenated), as well as to detect the presence of minerals, is currently one of the most powerful techniques for coal characterization and thus is of paramount importance in the various utilization procedures of coal (industrial combustion, coke production processes, etc.). FT-IR study shows the presence of aliphatic -CH, -CH2 and -CH3 groups, aliphatic C-O-C stretching associated with -OH and -NH stretching vibrations and HCC rocking. It is conjectured that, the two-stage leaching using HNO3 followed by HF remarkably reduced the ash content as well as the minerals including Al, Si and Ca. The solubilization of samples with buffered EDTA could not eliminate the minerals in coal. The silicate and kaolinite bands showed a systematic lowering on EDTA and carboxylic acid treatment. The fungal leaching was most beneficial for aromatic molecules with different degrees of substitution. The intensity of bands due to carbonyl groups was increased, when treated with fungi, whereas that due to oxygen functional groups showed a reverse trend. The mineral bands due to silicates also decreased in intensity, on post treatment with fungal culture.

International Journal on Theoretical and Applied Research in Mechanical Engineering , 2013,
Abstract: The three dimensional Reynolds Averaged Navier Stokes (RANS) Computational Fluid Dynamics analysis has been employed to study the influence of geometrical shape transition on performance of scramjet isolators. The pre-combustion shock train also called pseudo shock which appears in the subsonic combustion mode in dual mode scramjet isolator is analyzed in shape transitioned isolators. A square isolator and a shape transitioned square to circular isolator configurations having same length and cross sectional areas were considered. The simulations were carried on isolator geometries for inlet conditions of Mach 2 and unit Reynolds number of 12.4x106/m. The pressure rise due to heat addition in combustion chamber is modeled with back pressure 3.8 times higher than the inlet static pressure. The Numerical results match with the experimental data obtained from literature and with the waltrup and Billig correlation. The length of pseudo shock is compared in these isolators and it is found that it is shorter for square to circular configuration.
A Framework for the Engineering of Reliable Distributed Systems
ChandraBose A Dr.K.Alagarsamy
International Journal of Computer Trends and Technology , 2012,
Abstract: Engineering distributed systems is a challenging activity. This is partly due to their intrinsic complexity, and partly due to the practical obstacles that developers face when evaluating and adjusting their design and implementation decisions. This paper aims to design framework to automate experiments. Keeping all facts, experiment automation framework is designed in a generic and programmable way to be used with different types of distributed systems for wide-ranging experimental goals. The models are used by generative techniques to automate construction of a control system for deploying, executing, and post-processing the specific experiment. We have validated our approaches by performing experiments with a variety of distributed systems on different test beds to achieve wide-ranging experimental goals.
Politics as a Profession  [PDF]
Ankit Kumar Manoj, Dinesh Sridharan, Manoj Kulandaivel
Open Journal of Political Science (OJPS) , 2016, DOI: 10.4236/ojps.2016.62018
Abstract: The proposed research is about the people’s perception about “Politics as profession”. This paper examines multiple case studies of people’s opinion about making career in politics and further explains why most of the people are not interested in politics. By and large, people in India consider Politics as “dirt”. The word “Uneducated” is directly linked with politicians in India. We have our own Indian Political history as background information for us to understand people’s mentality towards politics and why most of us never want to join it. The purpose of this paper is to study the mentality of Indian parents about letting their children pursue politics as their profession. The main objective of this research is to make people understand that we can never clean the dirt by just staying away from it. Results of various surveys have been included to support the fact that people are afraid to take politics as a career. Post-Independence Era has seen kith and kin of late famous political figures that have entered politics in spite of being uneducated. Education doesn’t just mean acquiring degrees from some university, but to have a sense of honor towards leading people. This paper also stresses on the fact that most people agree on having an educated politician but most of the educated people are not interested in joining politics. As we know, many Indian politicians shroud in fake degree scandal, which shows the education status of politicians in India. Our proposal signifies that people need to change their mentality about politics and join it in true professional spirit so that we can be a developed nation and present an example to the rest of the world.

Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.21008
Abstract: A chromate-removing strain was isolated from spent chrome effluent and identified as Bacillus circulans strain MN1. The isolated strain was studied for resistance to Cr (VI) and its ability to remove Cr (VI). The strain was found to tolerate Cr (VI) concentration as high as 4500 mg/L, but the cells growth was heavily influenced when initial Cr (VI) concentration was increased between 1110 mg/L and 4500 mg/L while Cr(VI) at 500 mg/L to 1110 mg/L did not suppressed the cells growth. The experiments also demonstrated that the cells removed toxic Cr (VI) more efficiently at 30?C compared with that at 25?C and 35?C. The optimum initial pH for Cr (VI) removal was 5.6 and final pH values of 5.1-5.6 were observed for initial pH 5.2-5.7.

B. Manoj, Ponni Narayanan
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2013, DOI: 10.4236/jmmce.2013.12008

A high volatile bituminous coal was subjected to a series of organic acid treatment in steps using citric acid (1 hr and 2 hr) and buffered EDTA with acetic acid (1 to 3 hr) at room temperature. Leaching was performed with acetic acid (2N) also for 1 hr. Citric acid procedure reduced the mineral matter below 1.94%. Calcites and aluminates are completely removed along with substantial quantity of silicates by citric acid leaching. The change in absorption of organic functional groups and mineral matter in coal samples were studied using Fourier transform infrared spectroscopy (FTIR). Analysis indicated that oxygen containing species were decreased in the coal structure during acetic acid and citric acid (40%) procedure and buffered EDTA 3 hours leaching. As the period of leaching with buffered EDTA increased from 1 hr to 3 hr, organic functional groups and mineral functional groups decreased its intensity. The results indicated that the described acid treatment procedures with citric acid have measurable effects on the coal structure.
