Keeping it together: How to design legal protection against multiple and inters...
Côrte-Real, P.; Rego, M. L.; Brilhante, J.; Resende, M. J.; Vale de Almeida, M.; Corcodel, V.This paper presents the development of a cohesive set of scientifically grounded recommendations aimed at harmonizing anti-discrimination protections. These recommendations, rooted in multidisciplinary knowledge, address the complexities of sequential, additive, and intersectional multiple discrimination. Through a multidisciplinary approach that combines Law, Social Anthropology, and Economics, this work uses ...
A new control strategy with saturation effect compensation for an autonomous in...
Margato, Elmano; Faria, José; Resende, M. J.; Palma, João Carlos Pires daThis paper presents a variable speed autonomous squirrel cage generator excited by a current-controlled voltage source inverter to be used in stand-alone micro-hydro power plants. The paper proposes a system control strategy aiming to properly excite the machine as well as to achieve the load voltage control. A feed-forward control sets the appropriate generator flux by taking into account the actual speed and ...
Combining mechanical commutators and semiconductors in fast changing redundant ...
Palma, J.; Resende, M. J.; Cordeiro, A.; Maia, J.Combining Mechanical Commutators and Semiconductors in Fast Changing Redundant Inverter Topologies Armando Cordeiro, João Palma, José Maia, Maria Resende Abstract – This paper presents some solutions for fast changing and “soft” commutation between main and redundant branches in fault-tolerant inverter topologies through the combination of mechanical commutators and semiconductors. The present study deals with ...
