This paper is a short review on the application of continuos-time random walks to Econophysics in the last five years.

El objetivo principal de éste trabajo es aplicar métodos topológicos para obtener resultados sobre flujos continuos determinados por ecuaciones diferenciales. Específicamente, aplicamos la teoría del Índice Conley demostrar que, bajo ciertas condiciones, existe un conjunto invariante que contiene una solución no trivial. La construcción este puramente topológica y depende flujo ecuación diferen...

A feature extraction method for images is presented. It is based on the classical concept of Distance Transformation (DT) from which we develop a generalization, the Continuos Distance Transformation (CDT). Whereas the DT can only be applied to binary images, the CDT can be applied to both binary and gray-scale or color pictures. Furthermore, we define a number of new metrics and dissimilarity ...

We present in this paper an automatic system for the segmentation of continuos speech. The segmentation algorithm has been implemented modifying the CDHMM system RES (Recognition Experimental System) for the automatic recognition of continuos speech. The segmentation task is performed as a phonetic recognition constrained by the grammar model built only on the exact sequence of uttered phonemes...

This paper presents a study of an auditory version of the game Towers of Hanoi. The goal of this study was to investigate the nature of continuos presentation and what this could mean when implementing auditory direct manipulation. We also wanted to find out if it was possible to make an auditory interface that met the requirements of a direct manipulation interface. The results showed that it ...

Electronic systems deal with signals that have a frequency spectrum with a wide range of frequency components. These frequency components require filter functions that may include isolation, rejection or attenuation depending on system implementation. Digital filters are systems that modify certain frequencies relative to others either by a digital computational process or by implementation of ...
