Bridging Sensing and Decision Making in Ambient Intelligence Environments
2009
Context-aware and Ambient Intelligence environments represent one of the emerging issues in the last decade. In such intelligent environments, information is gathered to provide, on one hand, autonomic and easy to manage applications, and, on the other, secured access controlled environments. Several approaches have been defined in the literature to describe context-aware application with techniques to capture and represent information related to a specified domain. However and to the best of our knowledge, none has questioned the reliability of the techniques used to extract meaningful knowledge needed for decision making especially if the information captured is of multimedia types (image…
Sensorless control of permanent magnet synchronous motors for wide speed range applications
2006
This paper deals with sensorless control of Interior Permanent Magnet Synchronous Motors (IPMS) based on the estimation of speed and rotor angular position. The above estimate is based on the injection of high frequency stator currents able to generate a signal similar to that generated by a resolver connected to the axis of the motor. A new digital algorithm has been designed to demodulate the above signal whose implementation can be carried out on the same DSP that processes the control algorithm. In this paper a new scheme of speed and angular position estimator is proposed and justified on the theoretic point of view. The experimental results here shown validate the effectiveness of the…
Sobre la identidad y procedencia del poeta Filóxeno y la autoría del ditirambo ???????
2019
El presente estudio pretende resolver la controversia en torno a la identidad y procedencia del poeta Filóxeno, célebre ditirambógrafo del siglo V-IV a.C. Para ello, hemos recopilado todos los testimonios que citan a personajes con el nombre de Filóxeno desde la primera mención de Aristófanes. La investigación ha revelado que existen varios individuos con el mismo nombre y rasgos comunes. No obstante, el examen de estos testimonios revela la existencia de un único autor de ditirambos: Filóxeno de Citera. Además, creemos que este poeta fue el autor del ditirambo ???????, que algunos editores atribuyeron falsamente a Filóxeno de Léucade. Posteriormente, reflexionamos sobre la identidad de Fil…
