This paper proposes semi-discrete and fully discrete hybridizable discontinuous Galerkin (HDG) methods for the Burgers' equation in two three dimensions. In spatial discretization, we use piecewise polynomials of degrees $ k \ (k \geq 1), k-1 l (l = k-1; k) to approximate scalar function, flux variable interface trace respectively. full discretization method, apply a backward Euler scheme tempo...

Certain characterizations of the discrete Lindley and Poisson-Lindley distributions, originally introduced by Bakouch, Jazi Nadarjah (2014) Sankaran (1970), respectively, are presented. Al-Babtain, Gemeay Afify (2020) revisited these distributions provided estimation methods actuarial measures as well their applications in medicine. This short note is intended to complete, some way, (2020)&...

Nowadays, numerical modelings play a key role in analyzing hydraulic problems in fractured rock media. The discrete fracture network model is one of the most used numerical models to simulate the geometrical structure of a rock-mass. In such media, discontinuities are considered as discrete paths for fluid flow through the rock-mass while its matrix is assumed impermeable. There are two main pa...
