The purpose of this paper is to investigate the EGM method and the behavior of a solid particle suspended in a twodimensional rectangular cavity due to conjugate natural convection. A thermal lattice Boltzmann BGK model is implemented to simulate the two dimensional natural convection and the particle phase was modeled using the Lagrangian–Lagrangian approach where the solid particles are treat...
this work presents a numerical analysis of entropy generation in γ-shaped enclosure that was submitted to the natural convection process using a simple thermal lattice boltzmann method (tlbm) with the boussinesq approximation. a 2d thermal lattice boltzmann method with 9 velocities, d2q9, is used to solve the thermal flow problem. the simulations are performed at a constant prandtl number (pr ...
A two-dimensional model of Al, Si ordering in alkali feldspar is formulated and used to calcul~tea ccurately the configurational entropy for the model. For this purpose, a new method called Independent Basic Unit or IBU is introduced. To compare the results with the exact values, this method is applied to the onedimensional model of albite. The results given by IBU are found to be accurate ...
due to the importance of “service quality and customerssatisfaction” subject, this study seeks to investigate and prioritize thefactors which are effective on service quality and customers satisfactionusing grey relational analysis (gra) method. in the case of statisticalpopulations with large sizes, none of the other methods can competewith gra from the viewpoint of calculation accuracy. the s...
in the water resources planning and management, rainfall is considered as the main representative factor of region's hydroclimate system. there is a high level of spatial and temporal variability in rainfall events. rain gauges are used for precipitation measurement in different points of the region. due to limitations of rain gauges development, it is impossible to measure the exact distr...
capra aegagrus is one of the most highly-valued animals of iran. this species is also consideredas one of the main food sources for the acinonyx jubatus venaticus, which are critically endangered.seasonalhabitat use of wild goat was studied from january 2011 to september 2012 in dareh anjir wildlife refuge,yazd, iran. we developed maximum entropy models in three seasons.this study aims to deter...
In this paper, the continuous optimal control theory is used to model and solve the maximum entropy problem for a continuous random variable. The maximum entropy principle provides a method to obtain least-biased probability density function (Pdf) estimation. In this paper, to find a closed form solution for the maximum entropy problem with any number of moment constraints, the entropy is consi...
The current study focuses on the problem of determining investment attrаctiveness of countries by means of monitoring regional stock markets. The method of using the permutation entropy as a model of investment attractiveness estimation is suggested. We have calculated the permutation entropy for the time series of stock markets of countries for the period from 2005 to 2018. The countries with ...
This paper is twofold. In the first part, we derive an improvement of the Rényi Entropy Power Inequality (EPI) recently obtained by Bobkov and Marsiglietti [10]. The proof largely follows Lieb’s [22] approach of employing Young’s inequality. In the second part, we prove a reverse Rényi EPI, that verifies a conjecture proposed in [4, 23] in two cases. Connections with various p-th mean bodies in...
