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…

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…

While biologists have been aware of the existence of native Mexican trouts for over a century, they have received little study. The few early studies that did muchmore than mention their existence began in the 1930s and continued into the…

Management of the knowledge acquired through the technical area, as well as the possibility of self-help for the users for routine troubleshooting; requires the implementation and use of the technology available in the business of media to which you have…

En el artículo se reflexiona de forma crítica acerca de la reciente generalización de la idea
que considera la geografía aplicada y la profesionalización de esta ciencia como un camino
idóneo para conseguir el reconocimiento social de la disciplina y,…

La Educación Ambiental (EA) es una de las herramientas fundamentales para desarrollar actitudes, opiniones, creencias y conductas apropiadas que vinculen las relaciones entre los humanos y el entorno natural de una forma más sustentable. Los talleres interactivos son una forma…

El falibilismo supone un desafío a la concepción tradicional del saber, pero es la razón que subyace a la valoración positiva de ciertos tipos de ignorancia. Una respuesta al desafío sería negar que la verdad de «p» sea una condición…

O trabalho apresenta formas de comunicação e educação científica elaboradas no âmbito do projeto de Comunicação da Ciência Florestal, com o intuito de responder à demanda por ações educomunicativas que proporcionem a ampliação do acesso do público leigo à informação…

Abstract

Recent research in early childhood education centres suggests that the classroom environment and educators' knowledge about computers are not at a level that would support computer learning opportunities. The purpose of the present study was to determine what…

We propose an organic approach to educational web-based systems where learning objects, operations on these objects, and actors that perform them are aggregated in meaningful ways. The users of a learning system must be able to observe it globally, at…
