    LISA Pathfinder satellite was launched on 3 December 2015 toward the Sun–Earth first Lagrangian point (L1) where the LISA Technology Package (LTP), which is the main science payload, will be tested. LTP achieves measurements ...
  • Range-only benthic rover localization off the central California coast 

    Masmitjà Rusiñol, Ivan; Gomáriz Castro, Spartacus; Río Fernandez, Joaquín del; Kieft, B; O'Reilly, Thomas C. (Antoni Mànuel, 2016-10-19)
    Article
    Accés obert
    Nowadays, the use of autonomous vehicles for ocean research has increased, since these vehicles have a better cost/performance ratio than crewed vessels or oceanographic ships. For example, autonomous surface vehicles can ...
  • Mechanical properties of Al2O3 inverse opals by means of nanoindentation 

    Roa Rovira, Joan Josep; Coll Valentí, Arnau; Bermejo, Sandra; Jiménez Piqué, Emilio; Alcubilla González, Ramón; Castañer Muñoz, Luis María; Llanes Pitarch, Luis Miguel (2016)
    Article
    Accés restringit per política de l'editorial
    In order to understand the mechanical behaviour of Al2O3 inverse opals, nanoindentation techniques have been implemented in material layers with three different microstructures, in terms of hollow or polystyrene spheres, ...
  • Model-based active damping control for three-phase voltage source inverters with LCL filter 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Morales López, Javier; Castilla Fernández, Miguel; Miret Tomàs, Jaume (2016-09-02)
    Article
    Accés obert
    This paper presents a robust model-based active damping control in natural frame for a three-phase voltage source inverter with LCL filter. The presence of the LCL filter complicates the design of the control scheme, ...
  • Degradation analysis of thin film photovoltaic modules under outdoor long term exposure in Spanish continental climate conditions.

    Article
    Accés restringit per política de l'editorial
    The present study analyses the degradation of thin film photovoltaic modules corresponding to four technologies: a-Si:H, a-Si:H/µc-Si:H, CIS and CdTe, under 5 years of outdoor long term exposure in Leganés, Spain. The ...
  • High efficiency ITO-free hybrid solar cell using highly conductive PEDOT:PSS with co-solvent and surfactant treatments 

    Mahato, Somnath; Gerling Sarabia, Luis Guillermo; Voz Sánchez, Cristóbal; Alcubilla González, Ramón; Puigdollers i González, Joaquim (2016-10-15)
    Article
    Accés restringit per política de l'editorial
    Hybrid organic/inorganic heterojunction solar cells were fabricated based on polished n-type crystalline silicon (c-Si) and p-type transparent conducting polymer poly(3,4-ethylenedioxythiophene):polystyrenesulfonate ...
  • Impedance alterations in healthy and diseased mice during electrically induced muscle contraction 

    Sánchez Terrones, Benjamin; Li, Jiabin; Geisbush, Tom; Bragós Bardia, Ramon; Rutkove, S. B. (2016-08-01)
    Article
    Accés obert
    Alterations in the health of muscles can be evaluated through the use of electrical impedance myography (EIM). To date, however, nearly all work in this field has relied upon the measurement of muscle at rest. To provide ...
  • A rapid, low-cost, and scalable technique for printing state-of-the-art organic field-effcet transistors

    Article
    Accés obert
    In the last few years exciting advances have been achieved in developing printing techniques for organic semiconductors, and impressive mobility values have been reported for the resulting organic field-effect transistors ...
  • WiSync: an architecture for fast synchronization through on-chip wireless communication 

    Abadal Cavallé, Sergi; Cabellos Aparicio, Alberto; Alarcón Cot, Eduardo José; Torrellas, Josep (2016-04-01)
    Article
    Accés obert
    In shared-memory multiprocessing, fine-grain synchronization is challenging because it requires frequent communication. As technology scaling delivers larger manycore chips, such pattern is expected to remain costly to ...
