    A Hybrid Metaheuristic-Based Approach for the Aerodynamic Optimization of Small Hybrid Wind Turbine Rotors por Herbert Acero, José F., Martínez Lauranchet, Jaime, Probst, Oliver, Méndez Díaz, Santos, Castillo Villar, Krystel K., Valenzuela Rendón, Manuel, Réthoré, Pierre Elouan

    Publicado 2014
    “…This work presents a novel framework for the aerodynamic design and optimization of blades for small horizontal axis wind turbines (WT). The framework is based on a state-of-the-art blade element momentum model, which is complemented with the XFOIL 6.96 software in order to provide an estimate of the sectional blade aerodynamics. …”

    Prony Method Estimation as a New Approach for Surge Comparison Testing in Turn Insulation Diagnostics for Three Phase Stator Windings por Trujillo Guajardo, Luis Alonso, Rodríguez Alfaro, Luis Humberto, Rodríguez Maldonado, Johnny, González Vázquez, Mario Alberto, Salinas Salinas, Fernando, Shih, Meng Yen

    Publicado 2023
    “…This article presents an evaluation of Prony method estimation and its implementation considerations for surge comparison test application in turn insulation diagnostics for three-phase stator windings. Surge testing diagnostics compares recorded surge voltage signals of motor winding, and a diagnostic is then defined with a defined value of EAR (error area ratio), which evaluates the difference between signals to determine a turn insulation diagnostic. …”

    Editor's message: beaming energy from the space por Aguilar Garib, Juan Antonio

    Publicado 2017
    “…Our society is consuming energy figures which are so large that sometimes they become meaningless when mentioned; electricity alone in 2012 was 20,900 TWH (IEA World energy statistics), 68% from fossil fuels, 11% nuclear and 21% ‘renewable’; the energy that comes from resources that are not significantly depleted by their use, such as sunlight, wind, rain, tides, waves and geothermal heat. It is estimated that energy consumed in the buildings (residential and commercial end users) accounts for 20.1% of this total ([International Energy Outlook 2016). …”

    Optimal policies for constrained average-cost Markov decision processes por González Hernández, Juan, Villarreal, César Emilio

    Publicado 2009
    “…We give mild conditions for the existence of optimal solutions for a Markov decision problem with average cost, under m constraints of the same kind, in Borel actions and states spaces. Moreover, there is an optimal policy that is a convex combination of at most m + 1 deterministic policies.…”
