Abstract

This paper investigates the post-buckling behavior of a slender axially inextensible elastic rod with pinned-fixed end. The set of five first order nonlinear ordinary differential equations with boundary conditions specified at both ends constitutes a complex two point boundary value problem. By using multisegment integration technique, the highly nonlinear boundary value problems are numerically solved.


Numerical approximation of a nonlinear parabolic partial differential equation

Vol. 5, No. 2
Author(s):
Samir K. Bhowmik

Abstract

We consider the Allen-Cahn model of phase transitions. We approximate the problem using finite difference method in space coupled with several explicit and implicit methods in time and compare the solutions. We present some numerical experimental results of such approximations.

Abstract

In his poetry, John Donne creates a unique style that embraces a constant battle of emerging reality and the realm of fantasy. This paper intends to show the presence of playful images and arguments, which grow even more fantastic, the more the poet is overwhelmed by the denials offered by the woman or the realities of the world.


Effects of land use changes on livelihood pattern of small farmers

Vol. 5, No. 2
Author(s):
Gautam Mondal

Abstract

In Bangladesh, the livelihood of rural people is dependent largely on agricultural activities but only the paddy production in small pieces of land is not sufficient to satisfy the needs for survival of the small farmers. So they started thinking about the alternative use of lands in order to get increased output from there small pieces of land and found a new way of using their scarce resource in mixed nature.


Factors related to childbearing in Bangladesh: a generalized linear modeling approach

Vol. 5, No. 2

Md. Hasinur Rahman Khan

Abstract

Childbearing is generally considered as an important and major determinant of large family size and rapid population growth, particularly in the countries where family planning is not widely practiced. Bearing more children produces substantial risks to the health of the mothers and the children. This paper aims to determine the different factors of childbearing among the ever-married women in Bangladesh.


Multiple outliers detection: application to research & development spending and productivity growth

Vol. 5, No. 2
Author(s):

Mohammed Naser

Abstract

Multiple outliers are frequently encountered in applied studies in business and economics. Most of the practitioners depend on ordinary least squares (OLS) method for parameter estimation in regression analysis without identifying outliers properly. It is evident that OLS totally fails even in presence of single outlying observation.

Abstract

The growth of regional economic cooperation arrangement is one of the major developments in the post World War II period. The formation of regional integration has been greatly successful in bringing historically hostile countries together. The classic example is the state in the European Union and the South East Asia where economic dimensions have brought long time foes in the same dais.


Comparing the performance of time series models for forecasting exchange rate

Vol. 5, No. 2
Author(s):
M.K. Newaz

Abstract

In this paper an attempt has been made to compare different time series models to forecast exchange rate. A survey of literature shows that continuous debate is going on whether exchange rate follows a random walk or it can be modeled; there is also a debate whether one should use structural models or time series models to forecast exchange rate.
