We simulated models of diffusion and aggregation in long pores of small widths in order to represent the basic … of molecular diffusion is also analyzed via models of lattice random walks biased along the pores. The aggregation at the … plugging, the average aggregation position slowly decreases with the number N of deposited particles approximately as N-0 …

aggregation depending on conditions on food and / or mortality. We propose a model that describes the corresponding dynamic and by … a linear stability analysis of homogeneous solutions and can identify and interpret the region of parameters where these …

An integral equation describing the statistics of small clusters in a system with rare aggregation centers is …–cluster aggregation in the small-cluster system. Several different dependences for the characteristic probability are used. A new form of …

We describe and evaluate a new method of aggregating heterogeneous households that allows for the representation of …

This paper shows that the compatibility between efficiency measures and the aggregation procedure is not enough to … considering the additive aggregation of cost efficiency indicators for production and advertising activities, which use different …

an aggregation problem affecting country specific measures of PCM levels, with PCM changes providing instead an unbiased …

We provide a generalization of Harsanyi (1995)'s aggregation theorem to the case of incomplete preferences at the … aggregation rules that are utilitarian in a generalized sense. Strengthening Pareto indifference to Pareto preference provides a …
