There is mounting evidence of an increasing gender gap in computer education, which translates into a similar gap in the information technology workforce in the United States. This study investigates whether gender difference in computer usage is carried over to Internet usage. This paper...

A new mathematical model shows that a direct subsidy for an improved wood stove is not the best way to promote its use in rural India. The possibility of multiple uses of woodfuel and its sustainability are also discussed.

Replacive ordering can occur in an alloy in a continuous mode by the development and amplification of concentration waves of appropriate wave vectors, k. Such processes known as spinodal clustering (k∼〈000〉) and spinodal ordering (k defining the relevant superlattice structure) become...

A direct derivation of the physical eigenvalue and eigenfunction for the three magnon bound state equation is given.

For inferential analysis of spatial data, probability modelling in the form of a spatial stochastic process is often adopted. In the univariate case, a realization of the process is a surface over the region of interest. The specification of the process has implications for the smoothness of...

For testing the statistical significance of a treatment effect, we often compare between two parts of a population; one is exposed to the treatment, and the other is not exposed to it. Standard parametric or nonparametric two-sample tests are commonly used for this comparison. But direct...

The family of density power divergences is an useful class which generates robust parameter estimates with high efficiency. None of these divergences require any non-parametric density estimate to carry out the inference procedure. However, these divergences have so far not been used effectively...

Our interest is in the problem where independent samples are drawn from two different discrete populations, possibly with a common parameter. The goal is to test hypothesis about the parameters involved in these two samples. A number of tests are developed for the above purpose based on the...
