Stochastic simulation of the economic viability of feedlot steers fed with different proportions of concentrate

open access: yesBioscience Journal, 2017
The economic viability of feedlot zebu bulls, slaughtered at 450 kg after 90 days of feeding with diets consisting of different proportions of concentrate in dry matter (40, 60 or 80%), was estimated using Monte Carlo simulations, with or without the ...

A reliable numerical analysis for stochastic dengue epidemic model with incubation period of virus

open access: yesAdvances in Difference Equations, 2019
This article represents a numerical analysis for a stochastic dengue epidemic model with incubation period of virus. We discuss the comparison of solutions between the stochastic dengue model and a deterministic dengue model. In this paper, we have shown

A New Stochastic Model Updating Method Based on Improved Cross-Model Cross-Mode Technique

open access: yesSensors, 2021
This paper proposes a new stochastic model updating method to update structural models based on the improved cross-model cross-mode (ICMCM) technique. This new method combines the stochastic hybrid perturbation-Galerkin method with the ICMCM method to ...

Stochastic Material Point Method for Analysis in Non-Linear Dynamics of Metals

open access: yesMetals, 2019
A stochastic material point method is proposed for stochastic analysis in non-linear dynamics of metals with varying random material properties. The basic random variables are parameters of equation of state and those of constitutive equation.
