  • A New ROV Design: Issues on Low Drag and Mechanical Symmetry

    This paper reports the design of a new remotely operated underwater vehicle (ROV), which has been developed at the Underwater Systems and Technology Laboratory (USTL) - University of Porto. This design is contextualized on the KOS project (Kits for underwater operations). The main issues addressed here concern directional drag minimization, symmetry, optimized thruster positioning, stability and layout of ROV components. This design is aimed at optimizing ROV performance for a set of differen...

    Improving the IEEE 802.15.4 Slotted CSMA/CA MAC for time-critical events in wireless sensor networks

    In beacon-enabled mode, IEEE 802.15.4 is ruled by the slotted CSMA/CA Medium Access Control (MAC) protocol. The standard slotted CSMA/CA mechanism does not provide any means of differentiated services to improve the quality of service for timecritical events (such as alarms, time slot reservation, PAN management messages etc.). In this paper, we present and discuss practical service differentiation mechanisms to improve the performance of slotted CSMA/CA for time-critical...

    Optimização dos parâmetros de um robô hexápode através de algoritmos genéticos

    Mestrado em Engenharia Electrotécnica e de Computadores Os robôs com pernas apresentam vantagens significativas quando comparados com os veículos tradicionais que apresentam rodas e lagartas. A sua maior vantagem é o facto de permitirem a locomoção em terrenos inacessíveis a outro tipo de veículos uma vez que não necessitam de uma superfície de suporte contínua. No entanto, no estado de desenvolvimento em que se encontram, existem vários aspectos que têm que ser necessariame...

    Multi-agent system for personalization of location-based services

    The current ubiquitous network access and increase in network bandwidth are driving the sales of mobile location-aware user devices and, consequently, the development of context-aware applications, namely location-based services. The goal of this project is to provide consumers of location-based services with a richer end-user experience by means of service composition, personalization, device adaptation and continuity of service. Our approach relies on a multi-agent system composed of proxy ...

    Tensile behaviour of single and double-strap repairs on aluminium structures

    In this work, an experimental study was performed on the influence of plug filling, loading rate and temperature on the tensile strength of single-strap (SS) and double-strap (DS) repairs on aluminium structures. The experimental programme includes repairs with different values of overlap length (LO=10, 20 and 30 mm), and with and without plug filling. The influence of the testing speed on the repairs strength is also addressed (considering 0.5, 5 and 25 mm/min). Accounting fo...
