344. 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...

345. 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 asupport 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....

346. 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#8217;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...

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#8217; assessment within institutions#8217;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,...

348. 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...

349. 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...

350. Hamilton-Jacobi Conditions for a Class of Impulsive Control Problems - Aníbal Castilho Coimbra de Matos; Fernando Lobo Pereira

351. A versatile acoustic beacon for navigation and remote tracking of multiple underwater vehicles - Nuno Alexandre Lopes Moreira da Cruz; Luís António Dias Madureira; Aníbal Castilho Coimbra de Matos; Fernando Manuel Ferreira Lobo Pereira

352. Small Size AUVs: Operation Results and New Mission Concepts - Nuno Cruz; Aníbal Matos; J. Borges de Sousa

353. Coordinated Operation of Autonomous Underwater and Surface Vehicles - Aníbal Castilho Coimbra de Matos; Nuno Alexandre Cruz

354. Dynamic Optimization in the Coordination and Control of Autonomous Underwater Vehicles - J. Borges de Sousa; Aníbal Matos; F. Lobo Pereira
The coordination and control problems arising in team composition and tasking of autonomous underwater vehicles are discussed in the framework of dynamic optimization. Team composition and tasking are specified in terms of sets and relations among the elements of these sets. Results from dynamic optimization and non-smooth analysis are used to show that these coordination and control problems can be phrased in terms of concepts such as invariance, solvability, monotonicity, and switchings among value functions.

359. A QUALIFICAÇÃO DE EDIFÍCIOS - EXPERIÊNCIAS E METODOLOGIAS - Jorge Moreira Da Costa; Hipólito Sousa; Ana Cunha; Pedro Magalhaes

360. Differential Inclusion Approach for Mixed Constrained Problems Revisited - Maria Do Rosário De Pinho; Igor Kornienko
Properties of control systems described by differentialinclusions are well established in the literature. Ofspecial relevance to optimal control problems are propertiesconcerning measurability, convexity, compactness of trajectoriesand Lipschitz continuity of the multifunctions mapping defining thedifferential inclusion of interest. In this work we concentrateon dynamic control systems coupled with mixed state-controlconstraints. We characterize a class of such systems thatcan be described by an appropriate differential inclusion soas exhibit good properties of the multifunction.We also illustrate the importance of our findings bytreating some applications scenarios.
