Desde hace algunos anos, la tecnologia movil dia a dia ha venido evolucionando; y hoy cuenta con mayor crecimiento e importancia en el desarrollo personal y profesional de individuos y organizaciones. El uso de la tecnologia movil resulta... more
Resumen. Este trabajo presenta una modificación del algoritmo de Hooke-Jeeves implementado en variantes de Evolución Diferencial para resolver problemas de optimización con restricciones. El algoritmo de Hooke-Jeeves promueve una mejor... more
Currently many applications require tracking moving objects, and that information is used to plan the path of motion or change according to the position of a visual target [1] [2]. Computer vision systems can predict the motion of objects... more
Ensuring equitable and inclusive access to educational services in Higher Education Institutions (HEIs) requires the development of strategies that consider the diversity of their academic members, administrative staff, and students, as... more
En este trabajo se presentan los resultados de un estudio realizado con estudiantes universitarios de las licenciaturas en Economia y de Informatica, con el objetivo de analizar las dificultades en la comprension del concepto de variable,... more
This paper introduces MineSP, a relational-like operator to mine sequential patterns from databases. It also shows how an inductive query can be translated into a traditional query tree augmented with MineSP nodes. This query tree is then... more
This paper describes the WHES system that enables the creation and evolution of data warehouses. WHES supports a data warehouse evolution model and its associated language MDL. Using a multidimensional approach, this allows one to define... more
It also presents a SQL-like language associated to this model, which offers expressions to create and change versions of multidimensional schemas.

Lo que se presenta en este documento es una experimentación sobre el desarrollo y los resultados de las pruebas realizadas de una aplicación para computadora, enfocadas a personas con discapacidad visual. Los objetivos del sistema... more
Tangible User Interfaces (TUIs) are those in which users interact with a digital system through the direct manipulation of physical objects (tokens). Tokens are directly linked to a certain data/functionality within the system, so... more
Nowadays, the realization and follow-up of a team activity takes place in different execution environments (e.g. mobile phone, PC) through the use of computer applications. This implies context changes that generate interruptions in the... more
Knowledge Graphs (KGs) can be used to provide a unified, homogeneous view of heterogeneous data, which then can be queried and analyzed. In this paper, we explore the use of KGs to analyze the Thermal Comfort (TC) of users in specific... more
Resumen. Los sistemas consientes del contexto utilizan datos obtenidos de diversas fuentes para adaptarse y proveer servicios de interés al usuario de acuerdo a sus necesidades, localización o interacción con el ambiente. Sin embargo, el... more
Modal logics forms a family of formalisms widely used as reasoning frameworks in diverse areas of computer science. Description logics and their application to the web semantic is a notable example. Also, description logics have been... more
