Purpose – The idea that knowledge management can be a potential source of competitive advantage has gained strength in the last few years. However, a number of business actions are needed to generate an appropriate environment and infrastructure for knowledge…

This paper presents an interactive computer simulator that can be used in the
field of practical training in Robotics. The tool can provide basic training for workers as
well as increase their knowledge about robotic concepts. The application offers a…

Este artículo describe la integración de ontologías en formato OWL como
fuentes de conocimiento externas de un sistema de diálogo. El presente trabajo se
centra en conseguir un agente que gestione cualquier ontología independientemente
del dominio y sin perder expresividad…

In most of the triathlon races, the 10km-run is critical to win and, just a few seconds, may separate the gold and the silver medal. To our best knowledge, no study has analyzed the biomechanical differences among the first qualified…

In this paper an adaptive fuzzy decentralized
control algorithm for trajectory tracking of robot manipulators is developed. The proposed decentralized control algorithm allows the overall closed-loop system to be stabilized while making the tracking error to be uniformly ultimately bounded…

Using the underlying idea of the current-mode control, a new dynamical, sliding-mode control for the boost dc-dc converter is proposed. Such controller is easy to design, robust under load and input voltage variations, exhibits fast response, does not depend on…

The ambiguity, robustness and performance of systems becomes increasingly evident as the complexity and size increase in industrial processes. Under these circumstances, conventional control techniques such as PID control, nonlinear feedback control, LQG control and H∞ control have several disadvantages…

The glacigenic boulders from the Hirnantian Don Braulio Formation of the Argentine Precordillera contain a well preserved shelly fauna allowing to a better knowledge of brachiopods and bivalves, but gastropods remain undescribed. The purpose of this paper is to give…

Although South America lost more megafaunal genera than any other continent during the Late-Quaternary Extinction event (LQE), little is known about the chronology, causes or dynamics of these extinctions, especially in the northern part of the continent. Fossil deposits in…
