Intuitionistic Fuzzy Sets Approach in Appointment of Positions in an Organization via Max-Min-Max Rule
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 6 From the myriads of research on the applications of intuitionistic fuzzy sets theory in decision making, one can easy say that intuitionistic fuzzy sets theory is of great importance in decision science due to its efficiency and reliability. Here, we proposed a new area of application of intuitionistic fuzzy sets theory in appointment of positions in an organisation using intuitionistic ...

The Variational Iteration Method for Analytic Treatment of Homogeneous and Inhomogeneous Partial Differential Equations
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 5 In this paper, the author used the variational iteration method (VIM) to find the analytical solution to homogeneous and inhomogeneous partial differential equations. Few numerical examples were presented to show the effectiveness and efficiency of the method. It was observed that by carefully chosen a very good choice of initial guess leads to a solution in a closed form. The method is ...

Bayesian Regression Method with Gaussian and Binomial Links for the Analysis of Nigerian Children Nutritional Status (Stunting)
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 4 Children’s nutritional status is a reflection of their overall health. Malnutrition is associated with more than half of all children deaths worldwide. A study into geographical variability of nutritional status of children in Nigeria was observed from geo statistical mapping and a continuous covariates stunting (height for age) that exhibit pronounced non-linear relatio...

Direct Estimation of Effects and Tests of Their Statistical Significance for the Case of One Autosomal Locus with Two Alleles
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 4 In previous papers, see the references, the author introduced methods for estimating effects directly in samples of individuals whose genomes had be sequenced for the cases of one and two or more quantitative traits. In these papers, no attention was given to developing procedures of testing the statistical significance of the estimated effects. This paper is devoted to the development o...

Some Relationships Between Infinite Product Identities, Continued-Fraction Identities and Combinatorial Partition Identities
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 4 The author establish a set of four presumbaly new results which depict the inter-relationship between Infinite Product Identities, Continued-Fraction Identities and Combinatorial Partition Identities. Several closely related q-identities such as (for example) Jacobi’s triple-product identity are also considered. ...

The Modied Simple Equation Method and its Applications in Mathematical Physics and Biology
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 4 In this paper, the modified simple equation method with the aid of Maple is used to obtain new exact traveling wave solutions of the system of shallow water wave equations, modified Benjamin-Bona-Mahony equation and nonlinear dynamics of microtubules-A new model. When these parameters are taken special values, the solitary wave solutions are derived from the exact traveling wave solution...

On Dynamical Systems Induced by the Adele Ring
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 4 In this paper, we construct a dynamical system induced by the Adele ring ; based on the dynamical systems induced by -adic number fields; for all primes : We study fundamental operator-theoretic and operator-algebraic properties of the corresponding crossed product operator algebra generated by such a dynamical system, via free probability. ...
A Comparative Analysis of the Contributions of the Agricultural Sector and the Industrial Sector towards the Development/Growth of the Nigerian Economy
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 4 The comparison of the contribution of agricultural sector and industrial sector towards the development/growths in the Nigerian economy between 2005-2014 were determined using Hoteling T-distribution procedure. The data were collected from National Population Bureau of Statistics (NBS) and two populations were studied, namely agricultural sector and industrial sector. Under these two pop...

A Class of Regression Estimator with Cum-Dual Product Estimator as Intercept
Published In: GJSFR Part: F: Mathematics & Decision Volume: 15 Issue: 3 This paper examines a class of regression estimator with cum-dual product estimator as intercept for estimating the mean of the study variable Y using auxiliary variable X. We obtained the bias and the mean square error (MSE) of the proposed estimator. We also obtained MSE of its asymptotically optimum estimator (AOE). Theoretical and numerical validation of the proposed estimator was do...
