  • Multiferroic and related hysteretic behavior in ferromagnetic shape memory alloys 

    Gebbia, Jonathan Fernando; Castán Vidal, Teresa; Lloveras Muntané, Pol Marcel; Porta Tena, Marcel; Saxena, Avadh; Planes Vila, Antoni (2017-08-29)
    Article
    Accés restringit per política de l'editorial
    We combine a Ginzburg–Landau model for a ferroelastic transition with the theory of micromagnetism to study the magnetostructural behavior leading to multicaloric effects in ferromagnetic shape memory alloys. We analyze ...
  • Experimental characterization of the transition to coherence collapse in a semiconductor laser with optical feedback 

    Panozzo, M.; Quintero Quiroz, Carlos Alberto; Tiana Alsina, Jordi; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (Institute of Physics (IOP), 2017-11-01)
    Article
    Accés obert
    Semiconductor lasers with time-delayed optical feedback display a wide range of dynamical regimes, which have found various practical applications. They also provide excellent testbeds for data analysis tools for characterizing ...
  • Multi-longitudinal-mode micro-laser model 

    Staliunas, Kestutis (2017-10-19)
    Article
    Accés restringit per política de l'editorial
    We derive a convenient model for broad aperture micro-lasers, such as microchip lasers, broad area semiconductor lasers, or VCSELs, taking into account several longitudinal mode families. We provide linear stability analysis, ...

    This paper applies the adaptive gradient descent method to the second-order generalized integrator (SOGI) filter in order to find an online estimation algorithm for the grid frequency, which leads to the proposal of three ...
  • A multi-version algorithm for cooperative edition of hierarchically-structured documents 

    Ribó, Josep Maria; Franch Gutiérrez, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2001)
    Text en actes de congrés
    Accés obert
    Several approaches do exist to solve the problem of editing a text document cooperatively in real time. We believe that those approaches could be improved in two ways: (1) preserving the intention of the participants in a ...
  • Design and optimization for vehicle driving cycle of rare-earth-free SynRM based on coupled lumped thermal and magnetic networks 

    López Torres, Carlos; García Espinosa, Antonio; Riba Ruiz, Jordi-Roger; Romeral Martínez, José Luis (2017-08-11)
    Article
    Accés restringit per política de l'editorial
    This work presents a range optimization of a SynRM (synchronous reluctance motor) and a PMaSynRM (permanent-magnet-assisted synchronous reluctance motor) according to a standard driving cycle, and the solutions obtained ...
  • Zero-flow offset variation in ultrasonic clamp-on flowmeters due to inhomogeneity and nonlinearity of pipe materials 

    Millán Blasco, Oliver; Salazar Soler, Jorge; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; García Hernández, Miguel J. (2017-11)
    Article
    Accés obert
    The objective of this paper is to measure the zero-flow offset variation in ultrasonic Clamp-on flowmeters produced by using pipes made of materials with a nonhomogeneous and nonlinear behavior. The evaluation of this ...
  • Series interline DC/DC current flow controller for meshed HVDC grids 

    Sau Bassols, Joan; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol; Hassan, Fainan (2017-07-30)
    Article
    Accés restringit per política de l'editorial
    This paper proposes a DC/DC Current Flow Controller (CFC) for meshed High Voltage Direct Current (HVDC) grids. The CFC has the advantage of a simplified structure that allows to use minimum number of switches when ...
  • Regenerative braking in electric scooters

    Text en actes de congrés
    Accés restringit per política de l'editorial
    Electric urban vehicles are in the spotlight of society since its autonomy dependence is not that high. Electric motorcycles and scooters are actually already reliable urban vehicles for short journeys. These vehicles can ...
  • Handling of unbalanced faults in HVDC-connected wind power plants 

    Schönleber, Kevin; Prieto Araujo, Eduardo; Ratés Palau, Sergi; Gomis Bellmunt, Oriol (2017-11)
    Article
    Accés obert
    High-voltage DC (HVDC) connections enable integration of wind power plants located very far from shore. The decoupled AC offshore grid comprises multiple WT converters, and the voltage magnitude and frequency is primarily ...
