      Losada Maseda, Jesús Javier; Castro-Santos, Laura; Graña-López, Manuel Ángel; García-Diez, Ana; Filgueira-Vizoso, Almudena (MDPI, 2020-09-03)
      [Abstract] The employer (owner) of the project wants to obtain the maximum profit for the money invested and the consultant (contractor) will try to give less for that money. The regulation of their relationship is based ...
    • Analysis of the Real Energy Consumption of Energy Saving Lamps 

      Graña-López, Manuel Ángel; Filgueira-Vizoso, Almudena; Castro-Santos, Laura; García-Diez, Ana (MDPI, 2020)
      [Abstract] Light emitting diode (LED) and compact fluorescent light (CFL) lamps are widely used because they are associated with low energy consumption and a reduced environmental impact. In the present paper, a study of ...

      [Abstract] The appearance of the SARS-CoV-2 pandemic on the world stage has implemented changes in all social activities and, therefore, in teaching at all educational levels. On the one hand, it is argued that the closure ...
    • Study of the Rotary Bending Fatigue Resistance of 30MnB5, 41CrS4 and 30MnVS6 Steels 

      García-Diez, Ana; Galán-Díaz, Juan José; Graña-López, Manuel Ángel; Toledano, Mar (MDPI, 2022)
      [Abstract] In this study, a comparative analysis of the fatigue behavior of four types of steels, three of quenching and tempering (30MnB5 subjected to two different heat treatments and 41CrS4) and one microalloyed (30MnVS6), ...
    • Study of the sustainability of electrical power systems: analysis of the causes that generate reactive power 

      Graña-López, Manuel Ángel; García-Diez, Ana; Filgueira-Vizoso, Almudena; Chouza Gestoso, Jesús; Masdías-Bonome, Antonio (MDPI AG, 2019-12-16)
      [Abstract] Reactive power is an important parameter in electrical power systems since it affects the efficiency of the system because it is not useful energy. It decreases the power factor of the system and limits the ...
