In this paper, we first introduce the incomplete extended Gamma and Beta functions with matrix parameters; then, establish some different properties for these new extensions. Furthermore, give a specific application Bessel function by using functions; at last, construct relation between confluent hypergeometric function.
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...
in this paper, we introduce a family of fractional-order chebyshev functions based on the classical chebyshev polynomials. we calculate and derive the operational matrix of derivative of fractional order $gamma$ in the caputo sense using the fractional-order chebyshev functions. this matrix yields to low computational cost of numerical solution of fractional order differential equations to the ...
Three-loop counterterms for the Standard Model (SM) revealed that matrix of anomalous dimensions ($\ensuremath{\gamma}$) quarks is divergent in $d\ensuremath{\rightarrow}4$ limit unless a carefully chosen non-Hermitian square-root $Z$ used textbook formula $\ensuremath{\gamma}$. Here, an alternative prescription given, which expresses $\ensuremath{\gamma}$ and $\ensuremath{\beta}$ functions dir...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
Importance of probability distribution functions in natural resource studies is increasing due to their effective roles in better understanding of vegetation structure and providing conceptual models of quantitative indices of plant species. The present study was performed to model the distribution of height and canopy area of Cionura erecta L. shrub, using probability distribution functions in...
this study investigated the functions, types and frequencies of code switching in the teachers and students discourse in elt classrooms. to this end, the participants of this study including two groups of teachers and students were selected. the first group of participants were two efl teachers teaching general english courses (at two different levels of proficiency) in an institutional program...
