A NOTE ON RESOLVENT CONVERGENCE ON A THIN DOMAIN
(Bulletin Of The Australian Mathematical Society, 2014-02-01) [Artigo]
In this paper we provide a new proof of strong convergence of resolvent operators associated with boundary value problems on thin domains.
A scalable re-ranking method for content-based image retrieval
(Information Sciences, 2014-05-01) [Artigo]
Content-based Image Retrieval (CBIR) systems consider only a pairwise analysis, i.e., they measure the similarity between pairs of images, ignoring the rich information encoded in the relations among several images. However, ...
Stability results for impulsive functional differential equations with infinite delay
(Nonlinear Analysis-theory Methods & Applications, 2012-12-01) [Artigo]
For a family of differential equations with infinitive delay and impulses, we establish conditions for the existence of global solutions and for the global asymptotic and global exponential stabilities of an equilibrium ...
On the effects of each term of the geopotential perturbation along the time I: Quasi-circular orbits
(Advances In Space Research, 2014-09-15) [Artigo]
This paper provides a useful new method to determine minimum and maximum range of values for the degree and order of the geopotential coefficients required for simulations of orbits of satellites around the Earth. The ...
Lefschetz coincidence class for several maps
(Journal of Fixed Point Theory and Applications, 2016-03-01) [Artigo]
The aim of this paper is to define a Lefschetz coincidence class for several maps. More specifically, for maps (Formula presented.) from a topological space X into a connected closed n-manifold (even nonorientable) N, a ...
FUNCTIONS AND VECTOR FIELDS ON C(CPn)-SINGULAR MANIFOLDS
(Topological Methods In Nonlinear Analysis, 2015-12-01) [Artigo]
In this paper we study functions and vector fields with isolated singularities on a C(CPn)-singular manifold. In general, a C(CPn)-singular manifold is obtained from a smooth (2n+1) -manifold with boundary which is a ...
Analysis of bistable and chaotic piezoelectric energy harvesting device coupled with diode bridge rectifier
(International Journal of Pure and Applied Mathematics, 2015-01-01) [Artigo]
Vibration energy harvesting has greatly expanded over the last few years. While linear vibration-based energy harvesting has received considerable attention in the literature, some current research is focused on the concept ...
On Anti-Periodic Solutions for a Class of Impulsive Retarded Functional Differential Equations
(Mediterranean Journal of Mathematics, 2017-08-01) [Artigo]
In this paper, some new results on the existence and uniqueness of anti-periodic solution for a first-order impulsive functional differential equation with delay are obtained. The main tool to be employed here is the ...
LOWER SEMICONTINUITY of PULLBACK ATTRACTORS FOR A SINGULARLY NONAUTONOMOUS PLATE EQUATION
(Electronic Journal of Differential Equations, 2012-10-28) [Artigo]
We show the lower semicontinuity of the family of pullback attractors for the singularly nonautonomous plate equation with structural dampingu(tt) + a(t, x)u(t) + (-Delta)u(t) + (-Delta)(2)u + lambda u = f(u),in the energy ...
Unsupervised manifold learning using Reciprocal kNN Graphs in image re-ranking and rank aggregation tasks
(Image And Vision Computing, 2014-02-01) [Artigo]
In this paper, we present an unsupervised distance learning approach for improving the effectiveness of image retrieval tasks. We propose a Reciprocal kNN Graph algorithm that considers the relationships among ranked lists ...
