We introduce two new measures of network robustness and apply them to four different strategies. The measures are independent from the number of nodes in the network and have the strong potential to cover a large portfolio of applications. Using the Monte-Carlo methods, we demonstrate how to...

In this work, a Monte Carlo simulation, based on standard Metropolis algorithm, has been applied to investigate magnetic properties of a ferrimagnetic nanoparticle, with a cubic shape and core–shell structure. The nanoparticle is constituted of spin-1/2 in the core surrounded by spin-3/2 in...

Thermodynamic properties of a DNA hairpin are investigated employing non-Boltzmann Monte Carlo simulation. We model the DNA hairpin as a polymer on a two dimensional square lattice. We Consider bond fluctuation model with each bead occupying four-sites. The system exhibits a transition from a...

The double perovskite (DP) Sr2CrReO6, with its high Curie temperature, is a good candidate for magneto-electric and magneto-optic applications. Thus, a theoretical study by Monte Carlo Simulation (MCS) and Mean Field Approximation (MFA) in the context of the Ising model is important for a better...

The influence of elastic interactions on the phase diagram of a two-dimensional model binary alloy with antiferromagnetic nearest and ferromagnetic next-nearest-neighbor-type interactions is studied by Monte Carlo simulations and finite size scaling techniques. The elastic interaction leads to a...

Effusion of an ideal gas through a small orifice when a drifting gas exists past the orifice, as well as the reverse process, are investigated through extensive two-dimensional Monte Carlo simulations. It is found that a net transport of particles takes place toward the side containing the...

We study generalizations of parallel tempering, also known as replica exchange method, that aim at maximizing the sampling of independent low energy configurations through enforcing random walks in temperature (or other control variables). The advantage of these techniques is the easily tunable...
