    • Measurement errors in multifrequency bioelectrical impedance analyzers with and without impedance electrode mismatch. 

      Bogónez Franco, Francisco; Nescolarde Selva, Lexa Digna; Bragós Bardia, Ramon; Rosell Ferrer, Francisco Javier; Yandiola, Iñigo (2009-06-03)
      Article
      Accés restringit per decisió de l'autor
      The purpose of this study is to compare measurement errors in two commercially available multi-frequency bioimpedance analyzers, a Xitron 4000B and an ImpediMed SFB7, including electrode impedance mismatch. The comparison ...

    • Modulation technique to reduce EMI in power multiconverters 

      Mon González, Juan; Gago Barrio, Javier; González Díez, David; Balcells Sendra, Josep; Fernández García, Raúl; Bogónez Franco, Francisco; Gil Galí, Ignacio (2009-04-05)
      Article
      Accés obert
      A new technique to reduce EMI in modular power multiconverters is described. The technique is based on a combination of switching frequency modulation and a variable delay between communication signals of the single ...

    • Online monitoring of myocardial bioprosthesis for cardiac repair 

      Prat Vidal, Cristina; Gálvez Montón, Carolina; Sánchez Terrones, Benjamín; Bragós Bardia, Ramon; Bogónez Franco, Francisco; Puig Sanvicens, Verónica (2014-07-01)
      Article
      Accés restringit per política de l'editorial
      Background/objectives The aim of this study was to develop a myocardial bioprosthesis for cardiac repair with an integrated online monitoring system. Myocardial infarction (MI) causes irreversible myocyte loss and scar ...

    • Performance of an implantable impedance spectroscopy monitor using ZigBee 

      Bogónez Franco, Francisco; Bayés-Genís, Antoni; Rosell Ferrer, Francisco Javier; Bragós Bardia, Ramon (2010-04-04)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper presents the characterization measurements of an implantable bioimpedance monitor with ZigBee. Such measurements are done over RC networks,performing short and long-term measurements, with and without mismatch ...

    • Reference values of the bioimpedance vector components in a Caribbean population 

      Nescolarde Selva, Lexa Digna; Núñez, Ana; Bogónez Franco, Francisco; Lara, Alcibiades; Vaillant, Guillermo; Morales, Ricardo; Rosell Ferrer, Francisco Javier (Elsevier, 2013-06-06)
      Article
      Accés obert
      Background & aims Application of bioelectrical impedance vector analysis (BIVA) requires comparison of an impedance vector to reference intervals derived from healthy subjects. The aim of this work is to obtain reference ...

    • Relationship between bioimpedance vector displacement and renal function after a marathon in non-elite runners 

      Nescolarde Selva, Lexa Digna; Roca, Emma; Bogónez Franco, Francisco; Hernández Hermoso, José A; Bayés Genis, Antoni; Ara, Jordi (2020-05-06)

    • SVC model for voltage control of a microgrid 

      Bogónez Franco, Francisco; Balcells Sendra, Josep; Junyent, Oriol; Jordà, Josep (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Low power renewable sources, connected to low voltage micro-grids, are becoming more and more common. Since there is a high degree of uncertainty on the availability of such sources, this causes problems of stability and ...

    • Towards on line monitoring the evolution of the myocardium infarction scar with an implantable electrical impedance spectrum monitoring system. 

      Bragós Bardia, Ramon; Sánchez Terrones, Benjamín; Guasch, Assumpció; Bogónez Franco, Francisco; Gálvez-Montón, C.; Puig, V.; Prat-Vidal, C.; Semino, C.E.; Bayés-Genís, Antoni (IEEE, 2012)
      Text en actes de congrés
      Accés obert
      The human heart tissue has a limited capacity for regeneration. Tissue and cellular therapies based on the use of stem cells may be useful alternatives to limit the size of myocardial infarction. In this paper, the ...
