Abstract
Acquired brain injury (ABI) is one of the main causes of death and disability in Portugal and other Western countries. ABI typically results in physical, cognitive and psychosocial deficits, leading to life-long dramatic changes in the quality of life (QOL) of patients and their families, with well-documented negative implications for their community integration. Independent mobility using means of transportation is considered a nuclear area of community integration for people with disabilities [3]. However, direct contact with reality is limited for this population. Virtual reality (VR) constitutes a promising alternative of approximation to real life that may help increase the level of generalization of skills developed in programs that use this kind of technology. However, research on VR effects is necessary. The main goal of our project is to study the use of VR technology in the rehabilitation of executive dysfunction and memory. A VR program, CARP-VR, is in development, consisting of environments that simulate reality, with which patients will interact, performing various tasks. It is expected that CARP-VR intervention will lead to cognitive gains and generalization of acquired capacities to real-life activities, reflecting an amelioration of patients' functional independence and QOL that will contribute for the integration of these patients.

Abstract
In recent years, wikis have gained a prominent position among web-based collaboration platforms. However, special practices and adaptations are necessary; when applying wikis to software documentation and other development activities. The Wikis for Software Engineering (Wikis4SE) workshop aims to bring together researchers and practitioners interested in the use of wiki technology in this domain. It serves as a forum for presenting new ideas and tools, and reporting on experiences, best practices, and newly discovered problems. The Wikis4SE'2009 workshop builds on the success of prior events at WikiSym'2008 and WikiSym'2007.

Abstract
Maintenance decisions in electricity markets are one of the most important strategic conflicts among power players. A generation company, for instance, is responsible for its assets but it is the Transmission System Operator's task to schedule the most suitable period for maintenance, preserving system reliability. This relationship is sometimes conflicting and can be seen as an obstacle to the maximization of profits of generation companies, as well as to the transmission system operator, since it is mandatory to keep the adequate risk-based level on overall system. In this paper, the attention is focused on this relationship. Moreover, it highlights the proposal of building a dedicated environment in order to improve and clarify the discussions about maintenance outage schedule for large equipments, using the agent-based technology. In order to illustrate the proposal, results with the IEEE-RTS are presented. © 2009 IEEE.

Abstract
The growing concern for the preservation of heritage in face of natural hazards led to the appearance of the Regional Framework Operation (OQR) NOE - Heritage and Prevention of Natural Hazards under the Community Initiative INTERREG III C. The OQR NOE, led by the Provence-Alpes-Cote d'Azur (PACA, France) region, together with the Northern Portuguese regional coordination agency (CCDR-N), Molise and Sicily regions (Italy) and eastern region of Attica (Greece) aimed at developing preventive measures to safeguard the cultural heritage due to occurrence of natural hazards. The main aims, were to undertake an evaluation of existing practices through a strategy of inter-regional cooperation among the partners NOE and develop concrete actions in the field including strategies for prevention, early warning and intervention adapted to the heritage, awareness and accountability of officials and local decision makers, implementation of trans European experience, development of new technologies, cooperation and support for Euro innovative operations. In this context arised the subproject (SP) GEORISK, that joined an inter-regional cooperation of the City Council Port (CMP), the Bureau de Recherches et Geologiques Mini (BRGM), the Department of Geology, Faculty of Science of the University of Porto (DGFCUP) and the Portuguese Institute of Architectural Heritage (IPPAR), now called the Institute for Management Architectural and Archaeological Heritage (IGESPAR). For the implementation of the SP four main lines of action were defined: (i) Know the methods of assessment of geological hazards in France and Portugal and to foster the exchange of experiences, (ii) identify the specific level of management in relation to heritage geological risks; (iii) define the relevant actions to develop from local and regional decision makers, and (iv) Prepare a "Map of Geological Hazards in Historic Area of Porto (ZHP), to then therefore define a set of management measures, prevention, protection and intervention that can be generalized to other similar cases and to preserve the existing assets and then outline a plan for sustainable recovery. With these objectives in mind we sought map and integrate in GIS all the available information in order to assess the main geologic hazards of Porto: slope stability and seismic hazard

Abstract
Complex production systems can produce more than one part type. For these systems, production rate and priority of production for each part type is determined by production controllers. In this paper, genetic fuzzy logic control (GFLC) methodology is used to develop two production control architectures namely "genetic distributed fuzzy" (GDF), and "genetic supervisory fuzzy" (GSF) controllers. Previously these controllers have been applied to single-part-type production systems. in the new approach the GDF and GSF controllers are developed to control complex production systems. The methodology is illustrated and evaluated using two test cases; two-part-type production line and re-entrant production systems. Genetic algorithm is used to tune the membership functions of input variables of GSF or GDF controllers. The objective function of the GSF controller minimizes the production cost based on work-in-process (WIP) and backlog costs, while surplus minimization is considered by GDF controller. The results show that GDF and GSF controllers can improve the performance of production systems. GSF controllers decrease the WIP level and its variations. GDF controllers show their abilities in reducing the backlog level but generally, production cost for GDF controller is greater than GSF controller.
