Modeling of a predator prey dynamic system with harvesting using the lattice gas approach

  This paper uses the lattice gas model to incorporate spatial and stochastic elements in a prey-predator dynamic system. In this system, the habitat is partitioned in two adjacent patches, one of them being a prey reserve. The habitat is populated by two competing prey and a common predator. In the reserve, prey harvesting is prohibited. In the other patch, harvesting of one of the prey is allowed at a...

Statistical modeling of wastage using the beta distribution

  This work attempts to fit a set of observed industrial wastage to the beta distribution using the Chi-square goodness of fit test and it was found to fit the beta distribution at 1% significance level. The mean and the variance of the wastage proportion were found to be 0.429 and 0.0395, respectively. The parameters of the beta distribution were α = 2.25 and β = 2.97. The skewness of the beta...
