  • Stability analysis of periodic orbits in a class of duffing-like piecewise linear vibrators 

    El Aroudi, Abdelali; Benadero García-Morato, Luis; Ouakad, Hassen; Younis, Mohammad (EDP Sciences, 2014)
    Conference lecture
    Open Access
    In this paper, we study the dynamical behavior of a Duffing-like piecewise linear (PWL) springmass-damper system for vibration-based energy harvesting applications. First, we present a continuous time single degree of ...
  • Fabrication of melt-textured cylinders and bars of (YBa2Cu3O7-Y2BaCuO5) superconductors

    Cylinders and bars of bulk YBa2CuO7-Y2BaCuO5 textured ceramic composites (123-211) have been prepared through different directional solidification processes. Green ceramic preforms for the directional solidification process ...
  • Sliding mode control of interconnected power electronic converters in DC microgrids 

    Stramosk, Vinicius; Benadero García-Morato, Luis; Pagano, Daniel J.; Ponce, Enrique (2013)
    Conference lecture

    In this work, a typical structure of cascaded converters present in DC microgrids is analyzed. From the control point of view, converters acting as loads add a nonlinear effect to the supply bus, caused by its constant ...

  • Nonlinear dielectric response of BaBi4Ti4O15 ceramics 

    Kumar, Sunil; Ochoa Guerrero, Diego A.; García García, José Eduardo; Varma, K.B.R (American Institute of Physics (AIP), 2012)
    Conference lecture
    Restricted access - publisher's policy
    Nonlinear dielectric response of BaBi4Ti4O15 ceramics synthesized via the conventional solid-state reaction route has been monitored over a wide range of electric field strengths (E0 = 0.5-5 kV/cm). Dielectric permittivity ...
  • Single-walled carbon nanotubes characterization by Electron Spin Resonance spectroscopy 

    Abiad Monge, Aida; Pérez Puigdemont, Jordi; Ferrer Anglada, Núria; Roth, Segmar (2010)
    Conference report
    Restricted access - confidentiality agreement
    Carbon nanotubes (CNTs) are interesting candidates for the development of new electronic devices and sensors due to their small size and their mechanical, optical and electrical properties [1-6]. Well-characterized ...
  • Nonsmooth pitchfork bifurcation in a dc-dc converter: coexisting attractors and intermittency 

    El Aroudi, Abdelali; Moreno Font, Vanessa; Benadero García-Morato, Luis (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
    Conference report
    Open Access
    In this paper we deal with the analysis of nonlinear dynamical behavior of a single inductor two inputs two outputs (SITITO) power electronics DC-DC converter. The system can be used to regulate generally two outputs (one ...
  • Single inductor multiple outputs interleaved converters operating in CCM 

    Benadero García-Morato, Luis; Moreno Font, Vanessa; Aroudi, A El; Giral, R. (IEEE, 2008)
    Conference lecture
    Restricted access - publisher's policy
    Feasibility of single inductor multiple outputs (SIMO) DC-DC converters, able to operate in continuous-conduction mode (CCM), is shown in this paper. The power stage combines simple structures based on boost for non-inverted ...
  • Preparation of top seeded YBa2Cu3O7 large single-domain tiles 

    Yu, R; Gomis Arbonès, Vicente; Piñol Vidal, Salvador; Sandiumenge, Felip; Mora Serrano, Javier; Carrera, Miquel; Fontcuberta, Josep; Obradors Berenguer, Xavier (1997)
    Conference lecture
    Restricted access - author's decision
    Single domain superconductors with diameters up to 40 mm have been prepared by top seeding growth using Nd123 melt textured ceramics as seeds. We show that the use of these seeds is preferred over MgO single crystals to ...
