La necesidad de resolver ecuaciones y sistemas de ecuaciones no lineales surge de manera natural en discretizar las ecuaciones integro-diferenciales que modelan los problemas de los que se encargan las diferentes ramas de ...
[EN] In this work we focus on the problem of approximating multiple roots of nonlinear equations. Multiple roots appear in some applications such as the compression of band-limited signals and the multipactor effect in ...
[EN] In this paper, we consider the problem of solving initial value problems and boundary value problems through the point of view of its continuous form. It is well known that in most cases these types of problems are ...
The theory of complex dynamics is usually applied to compare the global convergence
properties of different iterative methods, by obtaining the attraction basins for simple
polynomial equations in the complex domain. ...

We derive new iterative methods with order of convergence four or higher, for solving nonlinear systems, by composing iteratively golden ratio methods with a modified Newton's method. We use different efficiency indices ...

[ES] Recopilación histórica de métodos de cálculo del flujo óptico desde su comienzo hasta la actualidad, con especial
hincapié en el método de Lucas-Kanade y los métodos variacionales. Desarrollo de algoritmos para el ...
In this work we introduce a new form of setting the general assumptions for the local convergence studies of iterative methods in Banach spaces that allows us to improve the convergence domains. Specifically a local ...

In this paper, we present a simple experiment to introduce the nonlinear behaviour of oscillating systems in the undergraduate physics laboratory. The transverse oscillations of a spring allow reproduction of three totally ...

In this work we propose using phase diagrams to explain the dynamical behaviour of simple mechanical systems. First the motion of the system x (t) is experimentally measured, and then the derivatives, v(t) and a(t), are ...

One of the most important problems in 3D tracking is the occlusion effect produced by obstacles. To solve this problem, we have developed a tracking system based on optical flow and stereo vision, combined with adaptive ...
