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.

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

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...

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...

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...
