Chagas Parasites Detection through Gaussian Discriminant Analysis
Visual detection of Chagas parasites through microscopic inspection is a tedious and time-consuming task. In this paper we provide an algorithm based on Gaussian discriminant analysis for the task of Chagas parasites ... -
Composition of Web Services Using Markov Decision Processes and Dynamic Programming
We propose a Markov decision process model for solving the Web service composition (WSC) problem. Iterative policy evaluation, value iteration, and policy iteration algorithms are used to experimentally validate our ... -
QoS-Based web services selection using a hidden Markov model
Web services are a technology that has been growing rapidly since its inception earlier this century. They are so popular nowadays that they are being used for numerous purposes, spanning business, healthcare, ... -
Image denoising using the Gaussian curvature of the image surface
A number of high-order variational models for image denoising have been proposed within the last few years. The main motivation behind these models is to fix problems such as the staircase effect and the loss of image ... -
Usability evaluation of an augmented reality system for teaching Euclidean vectors
Augmented reality (AR) is one of the emerging technologies that has demonstrated to be an efficient technological tool to enhance learning techniques. In this paper, we describe the development and evaluation of an AR ... -
Mexican sign language alphanumerical gestures recognition using 3D haar-like features
The Mexican Sign Language (LSM) is a language of the deaf Mexican community, which consists of a series of gestural signs articulated by hands and accompanied with facialexpressions. The lack of automated systems ... -
A novel reinforcement learning architecture for continuous state and action spaces
We introduce a reinforcement learning architecture designed for problems with an infinite number of states, where each state can be seen as a vector of real numbers and with a finite number of actions, where each action ... -

Aplicación del proceso de experimentación a la Ingeniería de Software
Contrary to other engineering disciplines, Software Engineering (SE) is a young discipline, where at the moment, there is not enough solid knowledge that can be applied effectively by a software engineer. A way of building ... -

Una revisión sistemática en los marcos de trabajo de Desarrollo Software en las MiPyMEs productoras de software
Una revisión sistemática es considerada como un método o protocolo que permite sintetizar investigaciones científicas de diversas áreas, la Ingeniería de Software no es la excepción. En este artículo se presenta ... -
An automatic algorithm for the detection of Trypanosoma cruzi parasites in blood sample images
Chagas disease is a tropical parasitic disease caused by the flagellate protozoan Trypanosomacruzi (T. cruzi) and currently affecting large portions of the Americas. One of the standard laboratory methods to determine the ... -
Chagas Parasite Detection in Blood Images Using AdaBoost
The Chagas disease is a potentially life-threatening illness caused by the protozoan parasite, Trypanosoma cruzi. Visual detection of such parasite through microscopic inspection is a tedious and time-consuming task. In ... -
Food intake and nutrition in children 1–4 years of age in Yucatan, Mexico
Background: The National Health and Nutrition Survey 2006 (ENSANUT in Spanish) reported high rates of under-nutrition in children of Yucatan. Is food intake the main cause of under-nutrition in children of the state of ... -
On the geometry of null hypersurfaces in Minkowski space
The present work is divided into three parts. First we study the null hypersurfaces of the Minkowski space R1n+2, classifying all rotation null hypersurfaces in R1n+2. In the second part we start our analysis of the ... -
Constant mean curvature hypersurfaces with constant angle in semi-Riemannian space forms
We study constant angle semi-Riemannian hypersurfaces Mimmersed in semi-Riemannian space forms, where the constant angle is defined in terms of a closed and conformal vector field Zin the ambient space form. We show that ... -

Persistencia del razonamiento equívoco en álgebra. Una interpretación de su génesis escolar
Se analiza la persistencia de raciocinios equívocos vinculados a dificultades y errores algebraicos correlacionados con lógicas procedimentales relativas a la linealidad, extrapolación de propiedades, generalización, entre ... -
Gráficas lineales: un proceso de significación a partir de su uso en ingeniería
En este escrito se analiza el uso de gráficas lineales en una maestría en ingeniería con la intención de generar una base de significación para el desarrollo de pensamiento matemático funcional. Esta investigación de corte ... -
La resignificación de las gráficas lineales. Ejemplos desde una comunidad de ingeniería
En el presente escrito se presentan dos ejemplos extraídos de una comunidad de una maestría en ingeniería sobre cómo, mediante dos tipos de usos de las gráficas cartesianas (organización de información y mostrar procedimientos), ...
