166. Autenticación de personas a partir de la biometría de la región dígito palmar - Jia Li, Zai Jian; Ferrer Ballester, Miguel Ángel; Alonso Hernández, Jesús Bernardino; Travieso González, Carlos Manuel; Román Arbelo, Fabio
[ES] En este artículo se presenta un sistema novedoso para la autenticación automática de personas basado en un indicador biométrico de la mano: la huella de la región dígito palmar. La imagen de los pliegues de la base del dedo índice se ha tomado con una cámara digital comercial. Dichas imágenes han sido digitalmente procesadas con el fin de realzar las colinas y valles de los pliegues de la piel. Estas líneas son seguidas para establecer los puntos de bifurcación y término denominados minucias, los cuales forman el descriptor de la huella dígito palmar. Un clasificador basado en un umbral...

167. Implementación de un método de detección de contornos con precisión sub-pixel en un entorno gráfico y estudio comparativo para aplicaciones en imágenes 2D y 3D - Santana Cedrés, Daniel Elías

168. Técnicas de súper-resolución para la mejora de secuencias de vídeo comprimido - Marrero Callicó, Gustavo; Barreto Dos Santos, Dácil; López Suárez, Sebastián; Tarajano Beracoechea, Carlos; López Feliciano, José; Sarmiento Rodríguez, Roberto; Núñez Ordóñez, Antonio
[ES] El mercado de consumo actual ha incrementado de forma espectacular la demanda de sistemas que mejore la calidad de la imagen para aplicaciones que van desde el vídeo doméstico a las militares, pasando por la teledetección, la seguridad, la astronomía o las aplicaciones médicas. Para una determinada secuencia de imágenes, el proceso de súper-resolución permite mejorar la resolución de dicha secuencia, incrementando de forma notable su calidad visual. Este trabajo muestra una novedosa técnica basada en la aplicación de una etapa de pre-procesado que permite aplicar el algoritmo de súper-resolución para incrementar la calidad de la imagen sólo en...

173. Considerações acerca do complexo cientifico-tecnológico nas sociedades industriais - Fernandez, Brena Paula Magno
Foi nas modernas sociedades industriais que o crescimento econômico, associado à idéia de progresso, tornaram-se as bases para qualquer projeto social futuro. A ciência e a tecnologia, num processo ascendente que se inicia no sec. XVII, com a Revolução Científica, atravessa o Iluminismo (sec. XVIII), e culmina na Revolução Industrial (sec XIX), são identificadas, com nitidez da mesma forma crescente, como os fatores críticos no processo de realização desse ideário de crescimento e desenvolvimento econômicos de longo prazo. Como o historiador da ciência William Leiss (1972) já assinalara, a afinidade entre o ethos do capitalismo e o espírito da ciência moderna...

174. A Strategic Rail Network Optimization Model for Freight Transportation - Luis Maia; António Fidalgo Couto
An optimization model for a rail freight network was developed as a support tool for planning and policy decisions involved in the improvement of rail networks on a regional and national level. The model was based on a strategic traffic assignment model, which was designed to model macronetworks with a high aggregation level, and was exclusively designed for freight traffic. The model contemplates road and rail transport modes and considers two types of cargo: intermodal cargo, which is generally transported in containers and is easily interchanged between different modes at intermodal terminals, and general cargo, which represents all the remaining cargo....

175. A Tuning-AHELO Conceptual Framework of Expected Desired/Learning Outcomes in Engineering
The OECD Secretariat, at the invitation of the AHELO Group of National Experts, contracted the Tuning Association to undertake initial development work on learning outcomes to be used for valid and reliable assessments of students from diverse institutions and countries. The two disciplines selected for the AEHLO Feasibility Study are engineering and economics. Following the Tuning approach, academics from various regions and countries in the world reached consensus on definitions of expected learning outcomes for bachelor’s-type programmes in both disciplines. This Working Paper presents the outcomes of their work for the engineering discipline. Members of the Engineering Tuning-AHELO working group...

176. ASSESSMENT OF HIGHER EDUCATION LEARNING OUTCOMES - AHELO - FEASIBILITY STUDY REPORT VOLUME 1 - DESIGN AND IMPLEMENTATION
In 2008, the OECD launched the AHELO feasibility study, an initiative with the objective to assess whether it is possible to develop international measures of learning outcomes in higher education. Learning outcomes are indeed key to a meaningful education, and focusing on learning outcomes is essential to inform diagnosis and improve teaching processes and student learning. While there is a long tradition of learning outcomes’ assessment within institutions’ courses and programmes, emphasis on learning outcomes has become more important in recent years. Interest in developing comparative measures of learning outcomes has increased in response to a range of higher education trends,...

177. ICT and e-Business in the Construction Industry
This sector study by e-Business W@tch focuses on the construction industry (CI). It describes how enterprises in this industry use information and communications technology (ICT) for conducting business, assesses the impact of this development for firms and for the industry as a whole, and indicates possible implications for policy. Analysis is based on literature, interviews, case studies and a survey among decisionmakers in European enterprises from the CI about the ICT use of their enterprise. The sector covers the business activities specified in NACE Rev. 1.1 Groups F 45.2 and 45.3.1 The building of complete constructions (or parts thereof) and...

178. Linking police and hospital road accident records: how consistent can it be? - Marco Raul Soares Amorim; Sara Ferreira; António Fidalgo Couto
This paper presents the description of various steps to be applied in the linkage of road traffic accident records using the case study of the city of Porto, Portugal. The importance of this process is well recognized by institutions such as IRTAD (OECD/ITF) that are promoting the combination of various data sources to fully assess the consequences of road accidents and monitoring progress. The complexity of this process is mainly concerned with several issues found in the data sets; mistakes and missing values are frequently detected and there are only a few common data fields that can be matched by...
