We have developed a model for a life insurance policy. In this model the net gain is calculated by computer simulation for a particular type of lifetime distribution function. We observed that the net gain becomes maximum for a particular value of upper age of last premium. This paper is...

We study the effect of particle size-dispersity on solids and melting of solids by molecular dynamics simulation on a two-dimensional size-dispersed Lennard-Jones system. We find that size-dispersity disfavours solidification and on increasing the dispersity, the solid ‘melts’, at a critical...

The geometry of fracture patterns in a dilute elastic network is explored using molecular dynamics simulation. The network in two dimensions is subjected to a uniform strain which drives the fracture to develop by the growth and coalescence of the vacancy clusters in the network. For strong...

This report focuses on how we achieve water sustainability over long timescales - decades, even centuries from now. These timescales are important and relevant to our decisions about planning, infrastructure, and institutions today. Many of the methods we use to manage water, directly or...
