We devise a new algorithm to obtain the pair-connectedness function Per) for continuum-percolation models from computer simulations. It is shown to converge rapidly to the infinite-system limit, even near the percolation threshold, thus providing accurate estimates of Per) for a wide range of densities. We specifically consider an interpenetrable-particle(More)
One of the fundamental quantities which statistically characterizes a random system of interacting particles is the nearest-neighbor distribution function. We present computer-simulation results for two different types of nearest-neighbor distribution functions for random distributions of identical impenetrable (hard) spheres. We also report, for such(More)
Computer-simulation results are reported for the porosity of a model of two-phase random media composed of identical D-dimensional spheres (D = 2 or 3) distributed with an arbitrary degree of impenetrability A., 0<,1 < 1; A. = 0 corresponding to randomly centered or "fully penetrable" particles and A. = 1 corresponding to totally impenetrable particles. We(More)

The critical behavior of absorbing phase transitions for two typical models in the Manna universality class, the conserved Manna model and the conserved lattice gas model, both on a square lattice, was investigated using the natural initial states. Various critical exponents were estimated using the static and dynamic simulations. The exponents(More)
Validity of two scaling relations β = ν θ and z = ν /ν ⊥ widely known in absorbing phase transitions is studied for the conserved lattice gas (CLG) model and the conserved threshold transfer process CTTP) both in one dimension. For the CLG model, it is found that both relations hold when the critical exponents calculated from the all-sample average density(More)
