The dependence of amplitude and width of the solitons of Sagdeev Potential on plasma parameters is widely discussed. The range of Mach number has determined for solitary waves (SWs) with the help of critical Mach number. The solution of the Energy Equation obtained, has been discussed by expanding the expression for SP in the higher terms of φ . The different solutions of Energy Equation give us SWs, breakable waves, collapsible waves and SWs with spiky and explosive nature. The role of temperature ratio on the transformation of SWs to collapsible waves is discussed. With the help of standard values of plasma parameters relevant to such plasma environment, the results so obtained, are discussed. These results may help us to explain the nature of SWs in different astrophysical situations.</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences Influence of Ferrofluid Lubrication on Longitudinally Rough Truncated Conical Plates with Slip Velocity 2019-07-31T10:59:26+0530 M M Munshi A R Patel G M Deheri <p>The study focuses on analyzing the effect of slip velocity in the case of a Ferrofluid squeeze film when the surface of truncated cone-shaped plates has a longitudinal roughness. Each oblique to the bottom plate was utilized by the external magnetic field. The bearing surface has a roughness that is designed with the help of a random stochastic variable having a nonzero mean, skewness and variance. The load carrying ability of a bearing system’s surface is determined by calculating the dispersal of pressure in the system, which is calculated by using the associated stochastically average Reynolds’ equation. The graphs obtained from the study shows that there is a correlation between the longitudinal surface roughness and the bearing system performance. The magnetic fluid lubrication has a positive impact on a system’s bearing capacity. However, the load bearing capacity declines as a result of the effect of slip. A high negative skewness of the surface roughness also has a positive impact on a bearing’s load carrying capacity. One interesting finding shows that contrasting to the results of transverse roughness, standard deviation positively impacts the load bearing capacity. This investigation suggests despite the im-portance of aspect ratio and semi vertical angle is significant for performance enhancement, it is also essential to maintain the slip at the lowest level.</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences Radial Basis Neural Network for Availability Analysis 2019-07-31T11:02:17+0530 Deepika Garg Naresh Sharma <p>The appliance of radial basis neural network is demostrated in this paper. The method applies failure and repair rate signals to learn the hidden relationship presented into the input pattern. Statistics of availability of several years is considered and collected from the management of concern plant. This data is considered to train and calidate the radial basis neural network (RBNN). Subsequently validated RBNN is used to estimate the availability of concern plant. The main objective of using neural network approach is that it’s not require assumption, nor explicit coding of the problem and also not require the complete knowledge of interdependencies, only requirement is raw data of system functioning.</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences Influence of Mathematical and Astronomical Developments in Medieval Kerala on Vāstuśāstra 2019-07-31T11:02:56+0530 Rajasekhar P Babu T Jose <p>The contribution in the field of mathematics is unparalleled. The concept of zero and the place value system is alone sufficed to place India in a high pedestal. Historians were generally under the impression that Indian supremacy in Mathematics came to an end with Bhaskaracharya (1114–1185) who is also known as Bhaskara II.Recent researches and publications of books like ‘Crest of the peacock’ written by George Gheverghese Joseph, has brought out the marvelous achievements of Southern India, especially Kerala region after the period of Bhaskaracharya which produced many results surpassing the Europeans in its indigenous style till the advent of Western Education system in early 19th Cent. This medieval contribution includes mathematical analysis and first steps in Calculus and many outstanding discoveries in astronomy. These contributions in Mathematics as well as in Astronomy are now grouped and studied under the title “Kerala School”. Accordingly, Sangamagrama Madhava (14th Cent.), doyen of Kerala School, is recognized as the ‘Father of infinitesimal Analysis’.In this paper the attempt is made to analyse the influence of Kerala School in the development of traditional building science and architecture. This branch of knowledge is generally categorized under the term ‘Vāstuśāstra’.`</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences Commutativity of Prime Ring with Orthogonal Symmetric Biderivations 2019-07-31T11:03:39+0530 B Ramoorthy Reddy C Jaya Subba Reddy <p><img src="/public/site/images/ojsadmin/Untitled11.png"></p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences On Some Special Property of The Farey Sequence 2019-07-31T11:04:07+0530 Ripan Saha <p>In this paper, some special property of the Farey sequence is discussed.

It may contain necessary information of several properties of benzenoids. The PI-index of benzenoids and their characteristic graphs are compared by correlating it to a structural property (π-electron energy) of the benzenoids using MLR analysis. PI index being applicable to both trees and cyclic graphs, yielded required results for benzenoid and their characteristic graph.</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences Degree Based Multiplicative Connectivity Indices of Nanostructures 2019-07-31T11:06:00+0530 S Sunantha P Gayathri <p>The Multiplicative topological indices of Phenylenic, Naphatalenic, Anthracene and Tetracenic Nanotubes are calculated.

This technique was first suggested by W.A. Shewhart of Bell Telephone Company based on 3σ limits. M. Harry, the engineer of Motorola has introduced the concept of six sigma in 1980. In 6σ limits, it is presumed to attain 3.4 or less number of defects per million of opportunities. Naik V.D and Desai J.M proposed an alternative of normal distribution, which is named as moderate distribution. The parameters of this distribution are mean and mean deviation. Naik V.D and Tailor K.S. have suggested the concept of 3-delta control limits and developed various control charts based on this distribution. Using these concepts, control limits based on 6-delta is suggested in this paper. Also the moving average chart is studied by using 6-delta methodology. A ready available table for mean deviation is prepared for the quality control experts for taking fast actions.&nbsp;</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences Gaussian Neighborhood-prime Labeling of Graphs Containing Hamiltonian Cycle 2019-08-26T13:59:39+0530 N P Shrimali S T Trivedi <p>In this paper, we examine Gaussian neighborhood-prime labeling of generalized Peterson graph and graphs which contain Hamiltonian cycle.</p> 2019-03-06T00:00:00+0530 Copyright (c) 2019 Mathematical Journal of Interdisciplinary Sciences
