The evolution of the observed Hubble sequence over the past 6GYR
(2010-11-01)
During the past years we have confronted serious problems of methodology concerning the morphological and kinematic classification of distant galaxies. This has forced us to create a new simple and effective morphological ...
Wide tunable filters using a recirculating delay line with multi-reflections
(05/01/2002)
A ring resonator with multiple reflections as a tunable filter is proposed and analyzed in this paper. A coupler and two identical Bragg gratings are used to implement the internal reflections so an active filter with a ...
Towards Simple Interaction in the Classroom: an NFC Approach
(IADIS International Conference e-Learning 2008IADIS International Conference e-Learning 2008, 01/01/2008)
In a given environment, distributing different devices with computing capabilities around us opens up new possibilities. It allows simple and easy interaction between user and computer. In this work we propose an approach ...
Multi-sensor system using plastic optical fibers for intrinsically safe level measurements
(10/04/2004)
A system for measuring liquid level in multiple tanks using optical fiber technology has been developed. Oil field service industry or any sector requiring liquid level measurements in flammable atmospheres can be benefited ...
Teaching Software Engineering from a Collaborative Perspective: Some Latin-American Experiences
(09/03/2010)
Teaching software engineering has been recognized as an important challenge for computer science undergraduate programs. Instruction in such area requires not only to deliver theoretical knowledge, but also to perform ...
Supporting clinical information management by NFC technology
(2009-07-01)
Tele-monitorization is a problem with aging people living alone since the vital signs control is complicated for them. In this sense, some initiatives by adapting technologies make easy these controls. In this work we ...
A Perception System for Accurate Automatic Control of an Articulated Bus
(2010-07-02)
This paper describes the perception system for an automatic articulated bus where an accurate tracking trajectory is desired. Among the most promising transport infrastructures of the autonomous or semi-autonomous ...
Analytical Investigation of the Structural Fuse Concept
(2006-06-28)
Passive energy devices (PED) are useful to enhance structural performance by reducing seismically induced structural damage. Metallic dampers are one such PED. When they are designed such that all damage is concentrated ...
Floor Response of SDOF Systems with Metallic Structural Fuses
(2004-06-26)
The floor demands of Single-Degree-of-Freedom (SDOF) systems designed or retrofitted with metallic structural fuses are studied in this article. Floor velocity and acceleration are obtained and comparisons are made between ...
Improving the Language Active Learning with Multiagent Systems
(09/23/2009)
Nowadays, there is a growing need for providing novel solutions to facilitate active learning in dependency environments. This paper present a multiagent architecture that incorporates agents specifically designed to provide ...
