El ruido de conmutación generado por los circuitos digitales representa un problema importante que a menudolimita las prestaciones de los circuitos integradosdigitales y mixtos. éste ruido de conmutación estápresente en ...
En la presente tesis doctoral se ha realizado una serie de aportaciones para contribuir al desarrollo de los sistemas de comunicaciones móviles de tercera generación. Esta nueva generación de sistemas utilizará una técnica ...
Some electrical devices in direct current (DC) networks, under certain operating characteristics, behave as constant power loads (CPLs). This behavior is defined by presenting negative incremental resistance, compromising ...
El comportamiento de los sistemas actuales de reconocimiento del habla se degrada rápidamente en presencia de ruido de fondo cuando las etapas de entrenamiento y de test no pueden llevarse a cabo en las mismas condiciones ...
The continuous improvements of optical design tools and manufacturing technologies of free-form optical elements, allow the creation of new complex-shaped lenses that improve the performance of traditional optical systems ...
Las prestaciones de muchos sistemas de procesado de vozse degradan rápidamente en aplicaciones reales ante lapresencia de ruido. Para solucionar este problema lastécnicas de speech enhancement pretenden reducir esteruido ...

En els últims anys la importància de la polarització en les comunicacions òptiques ha crescut notablement com resultat de tres grans desenvolupaments:<br/>1. L'aparició de l'amplificació òptica ha fet que es produeixi un ...
The thesis seeks to demonstrate that during the period between 1986 and 2006, some of the principal cities of the Spanish metropolitan system1, have undergone significant change in terms of their European competitiveness. ...
The main purpose of this research is to conduct exploratory qualitative research to analyze the level of global leadership competencies and Total Quality Management (TQM) in Egyptian and Jordanian exporting companies and ...
This work concerns some problems in the area of survival analysis that arise in real clinical or epidemiological studies. In particular, we approach the problem of estimating the survival function based on interval-censored ...
In the last decades, quantum materials have received much attention in the field of condensed matter physics due, in part, to their exotic properties. These are difficult to understand as they result from multiple physical ...
In this thesis we focus on the Capacitated Minimum Spanning Tree (CMST), an extension of the minimum spanning tree (MST) which considers a central or root vertex which receives and sends commodities (information, goods, ...
The analysis of the computational aspects of strategic situations is a basic field in Computer Sciences. Two main topics related to strategic games have been developed. First, introduction and analysis of a class of games ...
The Doctoral Thesis builds and tests a theoretical model that evaluates the contribution of shared knowledge and information technology to manufacturing performance. This is achieved through a sectorial research study among ...
Dinoflagellates are one of the most abundant and diverse groups of microalgae. Many dinoflagellates are covered with cellulose plates, whereas others lack these plates and are hence referred to as athecate or unarmoured. ...
(English) Nowadays, Bicycle Sharing Systems (BSS) have become a popular and widespread transportation system across the world thanks to their multiple environmental and health benefits, and its successful support for urban ...
