1. Producción documental de acceso abierto de la comunidad de habla hispana en Educación Matemática para la educación media
Abstract We present results of a study which objective was the open access documental production characterization of the Spanish-speaking community in Mathematics Education for middle school. From a taxonomy of key terms specific to Mathematics Education, we made a semantic approach to the documentation content, which was produced by this community of teache

2. STATE ESTIMATION AND TRAJECTORY TRACKING CONTROL FOR A NONLINEAR AND MULTIVARIABLE BIOETHANOL PRODUCTION SYSTEM
ABSTRACT In this paper a controller is proposed based on linear algebra for a fed-batch bioethanol production process. It involves finding feed rate profiles (control actions obtained as a solution of a linear equations system) in order to make the system follow predefined concentration profiles. A neural network states estimation is designed in order to kno

3. Using linear algebra for protein structural comparison and classification
In this article, we describe a novel methodology to extract semantic characteristics from protein structures using linear algebra in order to compose structural signature vectors which may be used efficiently to compare and classify protein structures into fold families. These signatures are built from the pattern of hydrophobic intrachain interactions using

4. O teorema do índice para o círculo / The index theorem for the circle
We study the comparison algebra on the circle, we describe the Gelfand space of its quotient by the compacts and we give a formula to compute the index of its Fredholm operators. After that, we generalize the result to the matrices with entries in the comparison algebra and give an application to differential opperators in the circle.
