Mathematical modeling of thin-layer drying of shrimp
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 3
In this study, microwave drying behaviour of shrimp was investigated. The drying study showed that the times taken for drying of shrimp from the initial moisture contents of 3.103% (d.b.) to final moisture content of around 0.01% (d.b.) were 11.75, 7, 4.75 and 4 min in 200, 300, 400 and 500W, respectively. The drying data were fitted to 7 thin-layer drying models. The performances of the...

Hypergraph-based edge detection in gray images by suppression of interior pixels
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 4
This paper presents a new two-stage hypergraph-based algorithm for edge detection in noise-free gray images. The first stage consists of mapping the input image onto a hypergraph called the Intensity Interval Hypergraph (IIHG) associated with the image. In the second stage, each hyperedge is partitioned into two disjoint subsets, namely, the interior pixels and the edge pixels. The inter...

EFFECT OF IMPERFECTNESS ON REFLECTION AND TRANSMISSION COEFFICIENTS IN SWELLING POROUS ELASTIC MEDIA AT AN IMPERFECT BOUNDARY
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 2
The present investigation is concerned with the reflection and transmission of plane waves at an imperfect interface between two different swelling porous elastic media. The expression for various amplitude ratios due to the incidence of longitudinal wave in solid (PS), transverse wave in solid (SVS) are obtained for imperfect boundary and are deduced for normal stiffness, transversal st...

An Integral Involving Extended Jacobi Polynomial
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 5
An attempt has been made to establish an integral concerning the product of two H-function of several complex variables (Srivastava and Panda [8] with extended Jacobi polynomial [5]). Mainly we are using the series representation of H-function given by Olkha and Chaurasia [6,7]. By assigning suitable values to the parameters, the results can be reduced to many new, known and unknown resu...

New Finite Integrals of Generalized Meliin-Barnes Type of Contour Integrals
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 3
In the present paper, we obtain three new finite integral formulas. These formulas involve the product of a general class of polynomials and the generalized Meliin- Barnes type of contour integrals. Mainly we are using series representation of the H-function given by Agarwal [14], Agarwal and Jain [13]. These integral formulas are unified in nature and act as the key formulas from which ...

GLOBAL DYNAMICS OF CLASSICAL SOLUTIONS TO A MODEL OF MIXING FLOW
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 2
We study the long-time dynamics of classical solutions to an initial-boundary value problem for modeling equations of a two-component mixture. Time asymptotically, it is shown that classical solutions converge exponentially to constant equilibrium states as time goes to infinity for large initial data, due to diffusion and boundary effects. ...

An Efficient Class of Dual to Product-Cum- Dual to Ratio Estimators of Finite Population Mean in Sample Surveys
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 3
This paper considers a class of dual to product-cum-dual to ratio estimators for estimating finite population mean of the study variate using auxiliary variate. The bias and mean square error of the proposed estimator have been obtained. The asymptotically optimum estimator (AOE) in the class has also been identified along with its approximate bias and mean square error. Theoretical and ...

On The Response Of A Non-Uniform Beam Transvered By Mobile Distributed Loads
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 3
The problem being investigated in this paper is that of the response of non-uniform beam under tensile stress and resting on an elastic foundation. The fourth order partial differential equation governing the problem is solved when the beam is transverse by mobile distributed loads. The elastic properties of the beam, the flexible rigidity, and the mass per unit length are expressed as f...

Regression Analysis of Child Mortality and Per Capital Income
Published In: GJSFR Part: F: Mathematics & Decision Volume: 12 Issue: 1
Higher income may be a precondition for healthy environment and better health services. There is considerable evidence and academic debate regarding relationships between per capital income and various health indicators including child mortality. In this paper, we proposed a twovariable reciprocal regression model to establish the relationship between child mortality and per capital inco...
