Income distribution dependence of poverty measure: A theoretical analysis
Chattopadhyay, Amit K.; Mallick, Sushanta K. - In: Physica A: Statistical Mechanics and its Applications 377 (2007) 1, pp. 241-252
Using a modified deprivation (or poverty) function, in this paper, we theoretically study the changes in poverty with respect to the ‘global’ mean and variance of the income distribution using Indian survey data. We show that when the income obeys a log-normal distribution, a rising mean...

The fundamental diagram of pedestrian model with slow reaction
Fang, Jun; Qin, Zheng; Hu, Hao; Xu, Zhaohui; Li, Huan - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 23, pp. 6112-6120
The slow-to-start models are a classical cellular automata model in simulating vehicle traffic. However, to our knowledge, the slow-to-start effect has not been considered in modeling pedestrian dynamics. We verify the similar behavior between pedestrian and vehicle, and propose an new lattice...
