Little is known on how different levels of population heterogeneity and different patterns of human mobility would affect the course of an epidemic in terms of timing and impact. By employing a large-scale spatially-explicit individual-based model, based on a highly detailed model of the European populations and on a carefully analysis of air and railway transportation data, we provide quantita...

Evidences show that divorces are related to the ecnomy, the social contagious as well as to the existence of a gap of happiness between the couple. This paper deals with the mathematical modelling of divorces allowing the estimation of the future divorced population.We use a discrete population model and data from The Spainsh Statistic Institute.

Split execution is a common model for providing a friendly environment on a foreign machine. In this model, a remotely executing process sends some or all of its system calls back to a home environment for execution. Unfortunately, hand-coding split execution systems for experimentation and research is difficult and error-prone. We have built a tool, Bypass, for quickly producing portable and c...

Abstract—this paper develops a real-time traffic signal timing model which is to be integrated into a single intersection for urban road, thereby solving the problem of traffic congestion. We analyze the current situation of the traffic flow with release matrix firstly, and then put forward the basic models to minimize total delay time of vehicles at the intersection. The optimal real-time sign...

A large model can be split into smaller components where by assembly features can be created and attached onto the components so that they can be reassembled to form the original model. The assembly features may function as positioning or interlocking purposes depending on the mating requirement. This paper describes a method for creating assembly features onto the solid components automaticall...

We establish a connection between two population models by showing that one is the scaling limit of other, as grows large. In infinite model, individuals are split into subpopulations, carrying either selective advantageous allele, or disadvantageous one. The proportion disadvantaged in evolves according to Λ-Wright–Fisher stochastic differential equation (SDE) with selection, and genealogy des...
