The intrinsic factors that drive human mobility have remained unclear for decades. Our observations from both intra-urban and inter-urban trips demonstrate a general law of human mobility. Specifically, the probability that a trip will occur is inversely proportional to the size of population located inside a circle with radius equal to the travel distance centered at the trip origin. A simple parameterless rank-based model is presented; this model can predict human flows with a convincing fidelity. Moreover, existing models can be implemented as special cases of our model, suggesting that our model is stable at more spatial scales. Our model also creates a fundamental bridge between individual mobility and social relationships.

This paper presents a systematic way of making effort estimation for service oriented software. By outlining major governance processes identified from service oriented best practices, an effort estimation model based on Bayesian net is introduced. Effort estimation method and project application results based on this model have been discussed thereafter.
