A formulation of conditional states on steganalysis approach
In this paper, we present a consolidated formulation of conditional states from the perspective of steganalysis approach. It has been identified that the conditional states used in steganalysis approach include hypothesis testing, gaussion distribution, ...
First order unstructured algorithms applied to the solution of the euler equations in three-dimensions
In the present work, the Roe, the Steger and Warming, the Van Leer, the Harten, the Frink, Parikh and Pirzadeh, the Liou and Steffen Jr. and the Radespiel and Kroll schemes are implemented, on a finite volume context and using an upwind and unstructured ...
The solutions of initial value problems for nonlinear fourth-order impulsive integro-differential equations in banach spaces
In this paper, we investigate the maximal and minimal solutions for initial value problem of fourth order impulsive differential equations by using cone theory and the monotone iterative method to some existence results of solution are obtained. As an ...
Optimal design of circular plates with internal supports
The behaviour of circular plates with internal rigid ring supports is investigated. The material of plates is assumed to be an ideal elastic material obeying the Hooke's law. The case of an elastic circular plate supported at the edge and resting on an ...
A possible solution of trisection problem
A solution of the ancient Greek problem of trisection of an arbitrary angle employing only compass and straightedge and its algebraic proof are presented. It is shown that while Wantzel's [1] theory of 1837 concerning irreducibility of the cubic x3 - 3x ...
Optimization of conical shells of piece wise constant thickness
Conical shells with piece wise constant thickness subjected to the distributed transverse pressure and loaded by a rigid central boss are studied. In the paper the both, elastic and inelastic shells are considered. In the case of inelastic shells it is ...
Positive solutions of operator equations and nonlinear beam quations with a perturbed loading force
In this paper we are concerned with the existence and uniqueness of positive solutions for an operator equation x = Ax + λBx on an order Banach space, where A and B are nonlinear operators and λ is a parameter. By properties of cones we obtain that ...
Reentry flows in chemical non-equilibrium in three-dimensions
This work presents a numerical tool implemented to simulate inviscid and viscous flows employing the reactive gas formulation of thermal equilibrium and chemical non-equilibrium in three-dimensions. The Euler and Navier-Stokes equations, employing a ...
