GEOMATIC Techniques to Study the Ecological Processes of Field Data
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 4 Geometic techniques are widely applied in landscape ecology to quantify the spatial patterns exhibited within species and its associated root fungi. Several analyses have been developed and modified to improve the ability to detect and characterize the patterns by the growth of species and population in various scale. Analysis of spatial pattern for disease and pathogen are of interest f...

Application of Hankel Transform of I-function of One Variable for Solving Axisymmetric Dirichlet Potential Problem
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 4 In the present paper we have solved the well known Axisymmetric Dirichlet problem for a half-space using the Hankel transform of I-function of one variable. Hankel transform is much effective tool for solving the boundary value problems involving cylindrical coordinates. Here we have considered the Axisymmetric Dirichlet problem for a half-space which is mathematically characterized byBo...

We can do it: Experiential Learning Activities in Mathematics Courses for Liberal Arts Undergraduates
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 Mathematics courses are often the last place anyone would expect to find experiential learning. Yet liberal arts undergraduates can benefit greatly from experiential learning activities in their required math course, and it is easy for educators to incorporate such activities into these courses. The author describes his practice of providing an experiential project in his course, Mathema...

The Decimal Pre-Exponent
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 The decimal notation k is born from the necessity of finding a system of decimal metric units of wide spectrum, but as I soon saw, we can also use this as exponential notation in several expressions and mathematical operations. This way the decimal pre-exponent is a method of double functionality: Firstly as systems of decimal units, and second as decimal exponent for mathematical operat...

Mathematical Modeling of Strategic Treatments on Tumor Growth
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 We propose to contribute to the emerging body of cancer treatment research by developing and analyzing mathematical models of the treatment of tumor with various strategic treatments. We build on existing models of the immunology that are already successfully developed and then the effects of chemotherapy and interleukin-2 were applied to the model. Thus we build a mathematical model of ...

Exact Solutions for Wick-Type Stochastic Coupled KdV Equations
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 Wick-type stochastic coupled KdV equations are researched. By means ofHermite transformation, white noise theory and F-expantion method, three typesof exact solutions for Wick-type stochastic coupled KdV equations are explicitlygiven. These solutions include the white noise functional solutions of Jacobi elibtic function (JEF) type, trigonometric type and hyperbolic type. ...

Intuitionistic Fuzzy Sets in Career Determination
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 Intuitionistic fuzzy set has proven interesting and useful in providing a flexible framework or model to elaborate uncertainty and vagueness involved in decision making. In this paper, we proposed the application of intuitionistic fuzzy sets (IFS) in career determination. Solution is obtained by looking for the smallest distance between each student and each career. ...

Fractional Calculus Pertaining to Generalized H -Functions
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 This paper is devoted to study of a pair of unified and extended fractional integral operators involving the multivariable H-Function, I-Function and general class of polynomials. Mellin transforms of these operators are investigated. Further, some properties of these operators have also been investigated. On account of the general nature of the functions involved herein, a large number ...

Effect of Buoyancy Force on the Flow Field in a Triangular Cavity
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 3 In this paper, the effect of buoyancy force in a triangular enclosure are studied numerically. The governing differential equations are solved by using finite element method (weighted-residual method). Here the left wall of the triangle is assumed to be adiabatic, the right and horizontal wall are kept at cold and heated respectively. Also all the wall are assumed to be no-slip condition...

Improved Class of Ratio -Cum- Product Estimators of Finite Population Mean in Two Phase Sampling
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 2 In the present study, we have proposed a class of ratio-cum-product estimators for estimating finite population mean of the study variable in two phase sampling. The bias and mean square error of the proposed estimator have been obtained. The asymptotically optimum estimator (AOE) in this class has also been identified along with its approximate bias and mean square error. Comparison of ...
