The geometric primitive MatOrus
This paper explores the potential of forming hierarchical structures using a geometric primitive, that we called MatOrus, which is a 3D closed surface formed from a Bézier circle. Several MaTorii (a set of MatOrus) can be ... -
Sphere polygon interaction to fill volume objects
Volume computation can be approximated by filling with regular convex geometric primitives. Volume filling simulation using spheres in a 3D environment, requires the motion and interaction between the geometric primitives, ... -

Análisis de la evaluación de competencias y su aplicación en un Sistema de Gestión del Aprendizaje. Un caso de estudio.
Internacionalmente, el enfoque basado en competencias ha sido adoptado en todos los niveles educativos buscando mejorar la calidad de la educación. Sin embargo, aún existen lagunas en el proceso, especialmente en la ... -
Steganographic system for hiding information in TCP/IP packets
In this article we present a steganographic system that permits the sending, reception and recuperation of secret data hidden in the TCP/IP packet header fields that are often unused or that exhibit some intrinsic redundancy ... -
Design of an administration software system for academic events
This work presents the design of a software system for the management and administration of academic events in a higher education institution, which allows handling the information of the events in an efficient way, ... -
Development of a software for the basic learning of sign language in the eastern of the state of Yucatán, México
The objective of the present work is to show the development of a software employed as tool for the basic learning of sign language, which will allow to reduce the divide of lack of communication that exists between people ... -
Kaprekar’s routine in polynomial rings
The process of order, reverse and subtract is taken from integers right to polynomial rings with coefficients in a finite field. We do such essentially for prime fields but we also comment a little on non prime fields. ... -
Comparison of multihardware parallel implementations for a phase unwrapping algorithm
Phase unwrapping is an important problem in the areas of Optical Metrology, Synthetic Aperture Radar (SAR) image analysis and Magnetic Resonance Imaging (MRI) analysis. These images are becoming larger in size and, ... -
Reflexive conversation: Approach to the professional learning of pre-service mathematics teachers
This study examines how reflexive conversation (RC) conducts pre-service mathematics teachers to collective learning. Although the investigations on the development and learning of teachers have shown that reflection and ... -
A fast algorithm for a total variation based phase demodulation model
In this paper we introduce fast numerical algorithms for the solution of the model [Total variation regularization cost function for demodulating phase discontinuities, Journal Applied Optics, 53(11):2297-2301, 2014]. For ... -
Variational phase recovering without phase unwrapping in phase-shifting interferometry
We present a variational method for recovering the phase term from the information obtained from phase-shifting methods. First we introduce the new method based on a variational approach and then describe the numerical ... -

A multi-agent architecture for scheduling of high performance services in a GPU cluster
Nowadays, clusters containing multiple GPU nodes are widely used to execute high-performance computing applications. Diverse disciplines use these clusters to improve the performance of several services that consume high ... -
Intervención de la tecnología de Realidad Aumentada en la educación: Una Revisión Sistemática de la Literatura
Los autores presentan los hallazgos de realizar una Revisión Sistemática de la Literatura en torno a iniciativas educativas que incorporan la tecnología de Realidad Aumentada (RA). Sin lugar a dudas, la RA es una tecnología ... -
