The objective of this research is to elaborate an endogenous growth
model which allows us to examine the mutual interaction between economic
growth, labour market behaviour and population growth. We show how the
introduction of disequilibrium and some nonlinearities give…

The study of natural fluctuations has been of great interest for
economists for decades. Although the earliest formal models of business
cycles, around the 1950s, were endogenous (Hicks, Kaldor, Goodwin), the
dominant strategy during the most of the last century…

"Esta tesis se enfoca en la estabilización global de un avión planar de despegue y aterrizaje verticales (PVTOL, por sus siglas en inglés). Este sistema tiene una dinámica compleja que hace difícil el diseño de controladores orientados a resolver el…

U.S. copyright law is facing an interesting moment, where technology is far ahead of the law, and where the evolution of law seems to lead nowhere. This article focuses on recent technological evolution and subsequent legal developments, especially the safe…

Software technology is creating a ubiquitous context for human living and learning in which new modes of interaction are gradually being incorporated. At the same time, interaction with Internet-based learning systems has evolved from using the traditional access from a…

Introduction: The use of computer-generated 3-dimensional (3-D) anatomical models to teach anatomy has proliferated. However, there is little evidence that these models are educationally effective. The purpose of this study was to test the educational effectiveness of a computer-generated 3-D…

From the earliest hardware and software days to the internet era, complexity of computer systems has been something computer scientists, engineers, and programmers have had to deal with. Important fields of research and technology have originated, developed, or matured as…

Following a classical conception of Artificial Intelligence (one that aims a definition of cognitive mechanisms and their implementation in computers), this thesis explores the problem of knowledge organization. In particular, it draws attention to the linguistic and semantic memory, trying…

Biclustering has become a very popular data mining technique due to its ability to explore at the same time two different dimensions, as opposed to clustering techniques, that make use of only one dimension. Gene expression data offer a suitable…

La separación de biomoléculas de alto valor añadido, con tamaño y características similares como la albúmina de suero bovino (BSA) y la lactoferrina (LF), representa uno de los retos más difíciles en la industria bioquímica. Durante 100 años las técnicas…
