kinetic monte carlo simulation was applied to investigation of kinetics and mechanism of oxalic acid degradation by direct and heterogeneous catalytic ozonation. la-containing perovskites including lafeo3, lanio3, lacoo3 and lamno3 was studied as catalyst for oxalic acid ozonation. the reaction kinetic mechanisms of each abovementioned catalytic systems has been achieved. the rate constants val...
In this article we discuss the multilevel Monte Carlo method for stochastic differential equations driven by jump-diffusion processes. We show that for a reasonable jump intensity the multilevel Monte Carlo method for jump-diffusions reduces the computational complexity compared to the standard Monte Carlo method significantly for a given mean square accuracy. Carrying out numerical experiments...
We compare empirical convergence of Monte Carlo and quasi Monte Carlo estimates of the H-period forecasts using the Cox-Ingersoll-Ross square root diffusion model. The behaviour of the quasi Monte Carlo estimates in high dimensions (H = 250) using both Euler scheme and the Brownian bridge discretisation is analysed. We find that quasi Monte Carlo estimator displays much higher convergence rate ...
Monte Carlo applications are widely perceived as computationally intensive but naturally parallel. Therefore, they can be effectively executed on the grid using the dynamic bag-of-work model. We improve the efficiency of the subtask-scheduling scheme by using an N-out-of-M strategy, and develop a Monte Carlo-specific lightweight checkpoint technique, which leads to a performance improvement for...
When a brine mixed with particles is frozen, some liquid water persists due to the freezing point depression caused by solute impurity, surface energy, and disjoining pressure (wetting forces). This unfrozen forms complex “liquid vein network” (LVN). However, details of process are still not fully understood, including permeability/tortuosity LVN, content at given temperature. Here, we have app...
