    Article
    Open Access
    Visual corona tests have been broadly applied for identifying the critical corona points of diverse high-voltage devices, although other approaches based on partial discharge or radio interference voltage measurements are ...
  • Germanium photovoltaic cells with MoO x hole-selective contacts

    Article
    Restricted access - publisher's policy
    Very thin, thermally evaporated MoOx (x¿<¿3) layer has been used as transparent hole-selective contact on an n-type Germanium substrate to effectively demonstrate PV conversion capability. The fabricated MoOx/Ge heterojunction ...
  • Enhanced chiral sensing with dielectric nanoresonators 

    García Guirado, José; Svedendahl, Mikael; Puigdollers i González, Joaquim; Quidant, Romain (2019-12-18)
    Article
    Restricted access - publisher's policy
    Chiro-sensitive molecular detection is highly relevant as many biochemical compounds, the building blocks of life, are chiral. Optical chirality is conventionally detected through circular dichroism (CD) in the UV range, ...
  • TCO-free low-temperature p+ emitters for back-junction c-Si solar cells 

    Martín García, Isidro; Coll Valentí, Arnau; López Rodríguez, Gema; Ortega Villasclaras, Pablo Rafael; Desrues, Thibaut; Orpella García, Alberto; Alcubilla González, Ramón (Elsevier, 2015-08-28)
    Article
    Open Access
    In this work, we report on the fabrication and characterization of n-type c-Si solar cells whose p+ emitters are based on laser processed aluminum oxide/silicon carbide (Al2O3/SiCx) films. The p+ emitter is defined at the ...
  • Reduced heart rate variability predicts fatigue severity in individuals with chronic fatigue syndrome/myalgic encephalomyelitis 

    Escorihuela, Rosa María; Capdevila, Lluis; Ramos Castro, Juan José; Zaragozà, María Cleofé (2020-01-06)
    Article
    Open Access
    Heart rate variability (HRV) is an objective, non-invasive tool to assessing autonomic dysfunction in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). People with CFS/ME tend to have lower HRV; however, in the ...
  • Predictive chiller operation: a data-driven loading and scheduling approach 

    Sala Cardoso, Enric; Delgado Prieto, Miquel; Kampouropoulos, Konstantinos; Romeral Martínez, José Luis (2019-01-01)
    Article
    Restricted access - publisher's policy
    The proper sequencing and optimal loading of chillers is one of the major avenues for energy efficiency improvement in existing heating, ventilating and air conditioning installations. The main enabler for the success of ...
  • Mapping the sustainable development goals into the EDINSOST sustainability map of bachelor engineering degrees 

    Sánchez Carracedo, Fermín; López Álvarez, David; Bragós Bardia, Ramon; Cabré Garcia, José M.; Climent Vilaró, Joan; Vidal López, Eva María; Martín Escofet, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    This Research to Practice Work in Progress paper presents the work conducted on the use of the Sustainability Map of Bachelor Engineering Degrees (a tool developed by the EDINSOST project) to analyze how Sustainable ...
  • Efficiency analysis of wide band-gap semiconductors for two-level and three-level power converters 

    Lumbreras Carrasco, David; Zaragoza Bertomeu, Jordi; Mon González, Juan; Gálvez, Eduardo; Collado Escolano, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Power devices based on wide band-gap materials are emerging as alternatives to silicon-based devices. These new devices allow designing and building converters with fewer power losses, and are thus more highly efficient ...
  • Novel methods to measure the gravitational constant in space 

    Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Ramos Castro, Juan José (American Physical Society (APS), 2019-09-20)
    Article
    Open Access
    We present two novel methods, tested by LISA Pathfinder, to measure the gravitational constant G for the first time in space. Experiment 1 uses electrostatic suspension forces to measure a change in acceleration of a test ...
  • A compact Thévenin model for a rectenna and its application to an RF harvester with MPPT 

    Gasulla Forner, Manuel; Ripoll Vercellone, Edgar; Reverter Cubarsí, Ferran (Multidisciplinary Digital Publishing Institute (MDPI), 2019-04-06)
    Article
    Open Access
    This paper proposes a compact Thévenin model for a rectenna. This model is then applied to design a high-efficiency radio frequency harvester with a maximum power point tracker (MPPT). The rectenna under study consists of ...
  • Common mode electronic noise in differential circuits 

    Serrano Finetti, Roberto Ernesto; Casas Piedrafita, Óscar; Pallàs Areny, Ramon (2019-07-01)
    Article
    Restricted access - publisher's policy
    Differential circuits are assumed to reject common-mode noise yet no parameter is available to describethat rejection as the Common Mode Rejection Ratio (CMRR) applies only to deterministic signals, not torandom noise. We ...
