The probability density function (PDF) of a random variable associated with the solution partial differential equation (PDE) parameters is approximated using truncated series expansion. PDE solved two stochastic finite element methods, Monte Carlo sampling and Galerkin method global polynomials. functional PDE, such as average over physical domain. are obtained considering number terms in Gram-...
In this research, modeling tree height distributions of beech in natural forests of Masal that is located in Guilan province; was investigated. Inventory was carried out using systematic random sampling with network dimensions of 150×200 m and area sample plot of 0.1 ha. DBH and heights of 630 beech trees in 30 sample plots were measured. Beta, Gamma, Normal, Log-normal and Weibull prob...
