When giving some away makes sense to jump-start the diffusion process

This paper uses an analytical model to examine when it makes sense to provide incentives to innovators to adopt a new product. The model allows for separate segments of innovators and imitators, each of which follows a Bass-type diffusion process. Interestingly “seeding” the market is optimal for a limited range of situations and these do not appear to include those where there is a downturn in...

When to Start Antiretroviral Therapy

When Regions Start to Move

In this paper, we discuss a formalism for modeling regions that are exposed to movement or deformation. The basis of our formalism is the RCC theory, which uses topological relations between regions to reason about them. By using fuzzy set theory and the notion of conceptual neighbors, we are able to deal with regions that can move or change over time. In addition, we introduce an algorithm for...
