In this paper, we consider perturbations to a sequence of moments associated with an orthogonality linear functional that is represented by a positive measure supported in [−1, 1]. In particular, given a perturbation to such a measure on the real line, we analyze the perturbation obtained on the corresponding measure on the unit circle, when both measures(More)
El caso general diagonal de los polinomios ortogonales de tipo Laguerre-Sobolev Abstract. We consider the family of polynomials orthogonal with respect to the Sobolev type inner product corresponding to the diagonal general case of the Laguerre-Sobolev type orthogonal polynomials. We analyze some properties of these polynomials, such as the holonomic(More)
One of the difficulties in process control education consists of providing a theoretical foundation maintaining the practicality. Experimental laboratories represent a powerful option to avoid this gap. An experimental laboratory must include industrial equipment and software systems in order to provide a real experience. However, industrial equipment(More)
The overall purpose of this project is to test the impact and potential benefits of Virtual and Augmented Reality technologies (AR&VR) to improve maintenance operation in industrial equipment. The main function for a Flapper valve of a Fuller-Kinyon type M pump is to prevent that the air generated to convey the bulk material through a conveying pipe(More)
This paper presents a methodology to evaluate the admissibility of actuator fault configurations (AFC) when Linear Constrained Model Predictive Control (LCMPC) is used. The methodology combines the use of structural and feasability analysis. Structural analysis allows to evaluate the loss of reachability after a fault occurrence. The results of the(More)
