We consider an extended form of the MX/M/c queue with two types server groups: Static as well dynamic (which turn on/off in a state-dependent manner) servers. The groups may have homogenous or non-homogenous service rates. model is further to feature setup and delayed-off times, finite capacity, k staffing levels. This class queues solved via difference equations approach, which addresses narra...

Abstract. We present results of the numerical investigation of the homogenous Dirichlet and Neumann problems to an age-sex-structured population dynamics deterministic model taking into account random mating, female’s pregnancy, and spatial diffusion. We prove the existence of separable solutions to the non-dispersing population model and, by using the numerical experiment, corroborate their lo...

In homogenous space Sol we study compact surfaces with constant mean curvature and with non-empty boundary. We ask how the geometry of the boundary curve imposes restrictions over all possible configurations that the surface can adopt. We obtain a flux formula and we establish results that assert that, under some restrictions, the symmetry of the boundary is inherited into the surface. MSC: 53A10

let  $varpi$ be a representation of the homogeneous space $g/h$, where $g$ be a locally compact group and  $h$ be a compact subgroup of $g$. for  an admissible wavelet $zeta$ for $varpi$  and $psi in l^p(g/h), 1leq p

in the present paper, an analysis was carried out to investigate effects of radiation on a free convection flow bounded by a vertical surface embedded in a porous medium with constant suction velocity. it was under the influence of uniform magnetic field in the presence of a homogenous chemical reaction and viscous dissipation with constant heat and mass flux. the non-dimensional governing equa...

In this paper we prove that the conjectures of Frisch and Parisi in 9] and Arneodo et al in 1] (called the multifractal formalism for functions) may fail for some non homogenous selfsimilar functions in m dimension, m 2. In these cases, we compute the correct spectrum of singularities and we show how the multifractal formalism must be modiied.
