Something New in Math: Meaningful Mathematics Courses for Liberal Arts Undergraduates
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 9
For over 100 years a vital if little known movement has been underway to allow liberal arts undergraduates to meet their math requirement with more meaningful and relevant options than the traditional skills courses in algebra, geometry, trigonometry, and calculus. Often referred to as liberal arts mathematics, and with a subset called humanistic mathematics, such courses may explore mat...

Exponential Estimators of Population Mean in Post-Stratified Sampling using Known Value of Some Population Parameters
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 9
This paper proposes some exponential estimators of the population mean in post-stratified sampling (PSS) scheme, when using known value of some population parameters. The bias and mean squared error of the proposed estimators are obtained up to first order approximations. Conditions under-which the proposed estimators perform better than other estimators, like the post-stratified samplin...

Some Results on Compactness in Bicomplex Space
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 9
In this paper, we have studied the continuity and compactness of the bicomplex space and its subsets. We have studied the compactness of some subsets of the bicomplex space in the idempotent order topology. We have also given a result regarding homeomorphism in the idempotent order topology and the complex order topology on the bicomplex space. ...

Enhanced (G^/G)-Expansion Method to Find the Exact Complexiton Soliton Solutions of (3+1)-Dimensional Zakhrov-Kuznetsov Equation
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 8
In this article, an enhanced ôˆºô€¡³ô€â€Â¢ ô€ˆ€ô€¡³ôˆ»-expansion method has been applied to find the traveling wave solutions of the (3+1)-dimensional Zakhrov-Kuznetsov (ZK) equation. The efficiency of this method for finding these exact solutions has been demonstrated. As a result, a set of comp...

Modelling Optimum Response in a Longitudinal Survey
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 8
Non-response rates in surveys have been recognized as important indicators of data quality since they introduce bias in the estimates which increases the mean square error. In order to reduce this error, previous studies have examined the effects of response predictors on response rates. There is dearth of information about models which focus on the interaction effects of response predic...

Prediction of Stock Price using Autoregressive Integrated Moving Average Filter ((ARIMA (p,d,q))
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 8
Abstract - The financial system of any economy is seen to be divided between the financial intermediaries (banks, insurance companies and pension funds) and the markets (bond and stock markets). This study was designed to look at the behavior of stock price of Nigerian Breweries Plc with passage of time and to fit Autoregressive Integrated Moving Average Filter for the prediction of stoc...

A Scientific Theory of Destiny
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 8
Destiny is the most complicated subject in our world and cannot be comprehended without taking a global view in both space and time. Therefore this paper takes a multi disciplinary approach using mathematics, physics, engineering, economics, and philosophy. The paper has two major related objectives (A) Provide a theory for the existence of destiny and (B) Explain away the counter logic....

Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 7
In the recent past, in many developing countries a good deal of research has been carried to solve the problems of ‘large basins’ whereas not much has been done with regard to the hydrologic problems of small watersheds. Small watersheds to play important roles e.g. a village pond catered by its own small watershed; in hilly watersheds, the generated runoff...

Lie Algebraic Approach and Complex Invariant Coupled Oscillator Systems
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 7
In classical mechanics, the system of coupled harmonic oscillators is shown to possess the symmetry applicable toa six-dimensional space in complex coordinates, two-dimensional phase space consisting of two position and twomomentum variables. In search into the features of a dynamical system, with the possibility of its complex invariant,we explore this dynamical systems. Dynamical algeb...
