Abstract -- In this paper, we talk about the importance of having a proper mathematical description when dealing with problems that originate in Engineering. We describe part of our work regarding the nonisothermal situatio
The energy of a graph is the sum of the absolute values of the eigenvalues of the adjacency matrix of the graph in consideration. This quantity is studied in the context of spectral graph theory,and is related to the sum of
The Richards’ equation describes mathematically the flow of water into the unsaturated soil zone. The model proposed here consists on applying adaptivity with h-refinement in finite element analysis and obtaining a numerical h-adaptive
This paper bases on the customer monetary spending model to propose the Hazard function to calculate the probability that customer purchase monetary more than a threshold baseline.This threshold baseline can be made by the company to control their minimum aven
Abstract -- In this paper we show that a complete and irredundant set ofGL(q,F)–conjugacy class representatives of the primitiveKeywords -- irredundant set, conjugacy class, representatives
A compound (mixture) distribution arises when all (or some) parameters of a distribution vary according to some probability distribution called the compounding (mixing) distribution. A well-known exampl
Abstract -- In this paper we prove a theorem of existence of a " good " solutionof a quantum model for a two-band Kane Hamiltonian system at the termalequilibrium.

Let G=(V,E) be a simple connected graph with vertex and edge sets V(G) and E(G), respectively. In chemical graph theory, the vertices of G correspond to the atoms and
Abstract -- Complexity of social issues and various problems of human life, made the scientists of recent centuries, to describe, analyze and optimize the behavior of social and community problem solving and using quantities models an
Abstract: In this paper, we will investigate the chaotic behavior for one-dimensional vector field to undergo a saddle node bifurcation, transcritical bifurcation and pitchfork bifurcation, and also, two-dimensional vector fields
In this communication, acontrollability problems for co-operative parabolic linear system involving Laplace operator with boundary Neumann control and distributed or boundary observations are considered.
This paper study some properties of martingales in a Banach space. In this paper, we also study the weak law of large numbers for matingales and we consider in the particular case the max convolution.
Let G=(E,V) be a simple connected graph with the vertex set V(G) and the edge set E(G). In this paper, we present an exact formula for the Zagreb indices and polynomials
Abstract:As the extension of PI index and vertex PI index, PI polynomial andvertex PIpolynomial aredistance-based topological polynomial which reflect certain structural features of organic molecules. In this paper, we determine thePI pol
In this paper we begin to study a nonlinear three dimensional continuous system with eight terms and three quadratic nonlinearities. The basic dynamical properties of the new system are analyzed by means of equilibrium point, stability and local bifur
