Abstract: In this paper, we present the space of functions of bounded - variation in the sense of Riesz – Korenblum, denoted by [ ], which is a combinations of the notions of bounded – variation in the sense of Riesz and of bounded – variation in the sense of Korenblum. In the light of this, we prove that the space generated by this class of functions is Banach algebra with respect to a given norm and we give a brief characterization of the composition (Nemystkii) operator on the space [ ].

Key words: Banach algebra norm, Bounded k - Variation, composition (Nemystkii) operator.

Abstract:The aim of this paper is to investigate matrix variate generalizations of multivariate Kummer-Beta and multivariate Kummer-Gamma families of distributions in the complex case. The multivatiateKummer-Beta and multivariate Kummer-Gamma families of distributions have been proposed and studied recently by Ng and Kotz. These distributions are extensions of Kummer-Beta and Kummer-Gamma distributions. Many known or new results have been made with the help of multivatiateKummer-Beta and multivariate Kummer-Gamma families of distributions.

Title	:	A Study of Classification and Discriminant Analysis of Infants at Birth in Nigeria
Country	:	Nigeria

Abstract:In Nigeria there is no recognized scientific method of discriminating and classifying babies statistically into groups of study.
The purpose of this study includes to set up a discriminant function and classification rule that can be used to classify babies into two groups; to estimate the proportion of observations in each of the prior group; and to estimate the probability of correct classification and misclassification respectively. To this effect, a sample of 270 cases (infants) was observed with the following measurements: Age of mother (x1), weight at 36th week (x2), birth weight (x3), Parity (x4), Gestation Period (x5), and sex of the baby (x6). The birth weight was used to do the initial classification. Group 1 termed underweight (< 2.5kg) and Group 2 termed normal weight (≥ 2.5kg). We observed that the Discriminant Function Z= -0.02947228X1- 0.0514773X2- 8.130338X3 + 0.062259X4 + 0.0946538X5 + 0.5888918X6. Also 95.8 % of the original grouped cases were correctly classified. The percentage of misclassification is 4.15%. Conclusively the measure of the predictive ability which is the percentage of correct classification shows that discriminant analysis can be used to predict infants into two classes of weight and can also be used to predict group membership of any subject matter.

Title	:	The Effect of Atmospheric Resistance, Magnetic Force and Oblateness of the Earth on the Motion and Stability of two satellites connected by an extensible cable in circular orbit of the Centre of Mass
Country	:	India
Authors	:	Vijay Kumar, Nikky Kumari
	:	10.9790/5728-0942732

Abstract:In a linear motion of a system of two satellites connected by extensible cable, one stable equilibrium point exists when perturbative forces like Solar radiation pressure, shadow of the earth, oblateness of the earth, air resistance and earth's magnetic force act simultaneously. We have obtained one stable point of equilibrium in case of perturbative forces like atmospheric resistance, Magnetic Force and oblateness of the earth acting together on the motion of a system of two satellites connected by extensible cable in the central gravitational field of earth in case of circular orbit of the centre of mass. We have used Liapunov's theorem on stability to examine the stability of the equilibrium point.
Keywords: Stability, Equiliribium Point, circular orbit, Liapunov Theorem, Satellites, perturbative forces.

Title	:	Radiation and thermal diffusion effect on a steady MHD free convection heat and mass transfer flow past an inclined stretching sheet with Hall current and heat generation
Country	:	Bangladesh
Authors	:	Mohammad Ali, Mohammad Shah Alam, Md. Mahmud Alam, Md. Abdul Alim
	:	10.9790/5728-0943335

Abstract: In the present paper is an investigation of steady MHD free convection, heat and mass transfer flow of an incompressible electrically conducting fluid past an inclined stretching sheet under the influence of an applied uniform magnetic field with Hall current and radiation effect. Using suitable similarity transformations the governing fundamental boundary layer equations are transformed to a system of non-linear similar ordinary differential equations for momentum, thermal energy and concentration equations which are then solved numerically by the shooting method along with Runge- Kutta fourth-fifth order integration scheme. The results presented graphically illustrate that primary velocity field decrease due to increase of magnetic parameter, Angle of inclination, Dufour number, Prandtl number, Heat generation and Soret number while secondary velocity also decrease for Hall parameter . Other parameters increase the velocities of the fluid flow. Temperature field increases in the presence of Dufour number, heat generation, Schmidt number, Magnetic parameter, Grashof number & Modified Grashof number and decreases for other parameters. Also, concentration profiles decreases for increasing the values of Dufour number, Schmidt number, Heat generation, Soret number, Grashof number & Modified Grashof number but concentration increases for other parameters. The numerical results concerned with the primary velocity, secondary velocity, temperature and concentration profiles effects of various parameters on the flow fields are investigated and presented graphically. Also the skin friction coefficient, the local Nusselt number and the local Sherwood number are presented in Tables 1-3.

Title	:	Effect of Michell function on the thickness of circular plate with internal heat generation
Country	:	India
Authors	:	Chetna M. Bhongade, Manohar H. Durge
	:	10.9790/5728-0946270

Abstract: The present paper deals with the determination of displacement and thermal transient stresses in a thick ( ) circular plate with internal heat generation. External arbitrary heat supply is applied at the upper surface of a thick ( ) circular plate, whereas the lower surface of a thick ( ) circular plate is insulated and the heat is dissipated due to convection in surrounding through lateral surface. Here we compute the effect of Michell function on the thickness of circular plate with internal heat generation. The governing heat conduction equation has been solved by using integral transform method and the results are obtained in series form in terms of Bessel's functions and the results for temperature change and stresses have been computed numerically and illustrated graphically.
