Minimal template size for Iris-Recognition

A method to achieve improvement in template size for an iris-recognition system is reported. To achieve this result, the biological characteristics of the human iris have been studied. Processing has been performed by image processing techniques, isolating the iris and enhancing the area of study, after which multi resolution analysis is made. Reduction of the pattern obtained has been obtained via statistical study.

Arquitectura telemática para la detección precoz de trastornos del lenguaje

La investigación y desarrollo de sistemas telemáticos en e-salud se ha limitado típicamente al despliegue de soluciones centradas en el acceso a la historia clínica electrónica. El presente trabajo aborda la complejidad de diseñar un servicio telemático capaz de ayudar al pediatra de atención primaria en el proceso de decidir si derivar o no a atención especializada a un niño de hasta seis años con posibles trastornos del lenguaje. Con esta finalidad, se ha construido una ontología a partir del análisis sistemático de 21 casos de niños ya diagnosticados y se ha desarrollado una plataforma web que facilita al pediatra su labor de detección precoz. Asimismo, se ha implementado una plataforma web para el especialista que permite validar la efectividad del sistema construido. El proceso de evaluación se ha completado con 21 casos de niños, diferentes de los 21 originales y extendiéndose a 160 niños de una escuela infantil.

Assessment of learning outcomes in computing studies

The assessment of learning outcomes is a key concept in the European Credit Transfer and Accumulation System (ECTS) since credits are awarded when the assessment shows the competences which were aimed at have been developed at an appropriate level. This paper describes a study which was first part of the project of the Bologna Experts Team-Spain and then developed as an independent study. It was carried out with the overall goal to gain experience in the assessment of learning outcomes. More specifically it aimed at 1) designing procedures for the assessment of learning outcomes related to these compulsory generic competences; 2) testing some basic psychometric features that an assessment device with some consequences for the subjects being evaluated needs to prove; 3) testing different procedures of standard setting, and 4) using assessment results as orienting feedback to students and their tutors. The process of development of tests to carry out the assessment of learning outcomes related to these competences, as well as some basic features regarding their reliability and validity is described and first results on the comparison of results achieved at two academic levels, will also be described at a later stage.
