Abstract  A position control algorithm for a beltdriven servomechanism of a laser-cutting machine is described. High-accuracy position tracking control procedure for the system with inherent elasticity due to the low-cost belt-driven servomechanism is derived using sliding mode motion control strategy and Lyapunov design. The control design results in continuos sliding mode control law. It pos...

This paper presents a method to obtain a single continuos polygonal mesh representing a branched structure taken from a tree and modelled by a L-systems-based method. A refinement process is made once the model of the tree is obtained. This process produces smooth transitions in the tree areas joining the branches. That is, the overlapping problems and geometry discontinuities are avoided. Beca...

The proposed Universal Intelligent Interface (UII) consists in two parts. One is a universal part, another is a problem depended part. UII, modeling user in the Frame Network User Model (FNUM), is designed as a shell system which supports a knowledge base and a number of learning agents. The system treats separately (not necessary independently) various elements of user model within the frames ...

Properly addressing the discretization process of continuos valued features is an important problem during decision tree learning. This paper describes four multi-interval discretization methods for induction of decision trees used in dynamic fashion. We compare two known discretization methods to two new methods proposed in this paper based on a histogram based method and a neural net based me...

Abstract The aim of this work is to present a continuos mathematical model that characterizes and enforces connectivity in topology optimization problem. That goal accomplished by constraining the second eigenvalue an auxiliary eigenproblem, solved together with governing state law each step iterative process. Our density-based approach illustrated 2d 3d numerical examples context structural de...

This paper investigates the processing of Frequency Modulated-Continuos Wave (FM-CW) radar signals for vehicle classification. In the last years deep learning has gained interest in several scientific fields and signal processing is not one exception. In this work we address the recognition of the vehicle category using a Convolutional Neural Network (CNN) applied to range Doppler signature. Th...

El propósito de este artículo es explorar la idea que, aun cuando Ceroidad fue acuñada por Deleuze y no Peirce, hay ningún problema en considerarla como el antecedente formal Primeridad. La argumentación mostrará sin Ceroidad, Dios habría podido transformar nada conjunto vacío y, tanto, crear los elementos Esto puede ilustrarse con un experimento mental, que se hace evidente vacío, habrían surg...

El estallido de una epidemia o pandemia es siempre un momento amenaza, emergencia e incertidumbre. Cuando la salud y vida las personas se pone en peligro requieren respuestas urgentes coordinadas por parte los agentes estatales a nivel nacional, regional global que tengan el potencial contener evitar su propagación. De esta situación continuos cambios normas imponen nuevas restricciones, obliga...
