      Projecte Final de Màster Oficial
      Accés obert
      El trefilado es un proceso de fabricación cuyo objetivo es dar el calibre necesario a los alambres. Este proceso produce un endurecimiento por deformación no deseado en el material. Para recuperar las propiedades iniciales ...

    • Green-pumped continuous-wave parametric oscillator based on fanout–grating MgO:PPLN 

      Sukeert, Sukeert; Kumar Suddapalli, Chaitanya; Ebrahim-Zadeh, Majid (2020-12-01)
      Article
      Accés obert
      We report the first green-pumped continuous-wave (cw) optical parametric oscillator (OPO) based on MgO:PPLN in a fanout grating design. Pumped by a single-frequency cw laser at 532 nm, the OPO provides tunable radiation ...

    • Increasing the robustness of digital circuits with ring oscillator clocks 

      Machado, Lucas; Roca Pérez, Antoni; Cortadella, Jordi (2017)
      Text en actes de congrés
      Accés obert
      Technology scaling enables lower supply voltages, but also increases power density of integrated circuits. In this context, power integrity becomes a major concern in the implementation of highperformance designs. This ...

    • Irregular collective dynamics in a Kuramoto–Daido system 

      Clusella Coberó, Pau; Politi, Antonio (2020-12-29)
      Article
      Accés obert
      We analyze the collective behavior of a mean-field model of phase-oscillators of Kuramoto–Daido type coupled through pairwise interactions which depend on phase differences: the coupling function is composed of three ...

    • Minimization of the capacitor voltage fluctuations of a modular multilevel converter by circulating current control 

      Picas Prat, Ricard; Pou Félix, Josep; Ceballos Recio, Salvador; Agelidis, Vassilios; Saeedifard, Maryam (2012)
      Text en actes de congrés
      Accés obert
      The modular multilevel converter (MMC) is one of the most potential converter topologies for medium/high power/voltage applications. One of the main technical challenges of an MMC is to eliminate/minimize the circulating ...

    • Noise-assisted energy transport in electrical oscillator networks with off-diagonal dynamical disorder 

      De León Montiel, J. Roberto; Quiroz Juarez, Mario A.; Quintero Torres, Rafael; Domínguez Juárez, Jorge Luis; Moya Cessa, Hector M.; Pérez Torres, Juan; ARAGÓN HERNÁNDEZ, JOSÉ LUÍS (Macmillan Publishers, 2015-11-27)
      Article
      Accés obert
      Noise is generally thought as detrimental for energy transport in coupled oscillator networks. However, it has been shown that for certain coherently evolving systems, the presence of noise can enhance, somehow unexpectedly, ...
