  • Estudio experimental del llenado de moldes pulvimetalúrgicos 

    Istúriz Mota, Álvaro; Riera Colom, María Dolores; Prado Pozuelo, José Manuel (2005-10)
    Article
    Accés obert
    En el proceso de conformado pulvimetalúrgico, la consolidación del polvo se inicia con el llenado del molde en el que se fabricará la preforma porosa, el cuál está caracterizado por la distribución de densidades del polvo ...

  • Joint symbol and chip synchronization for a burst-mode-communication superregenerative MSK receiver 

    López Riera, Alexis; Águila López, Francisco del; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Giralt Mas, Ma. Rosa; Moncunill Geniz, Francesc Xavier (2017-01-05)
    Article
    Accés obert
    In this paper we describe a superregenerative (SR) MSK receiver able to operate in a burst-mode framework where synchronization is required for each packet. The receiver is based on an SR oscillator which provides samples ...
  • A direct-sequence spread-spectrum super-regenerative receiver 

    Moncunill Geniz, Francesc Xavier; Mas Casals, Orestes Miquel; Palà Schönwälder, Pere (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Comunicació de congrés
    Accés obert
    Current applications of the super-regenerative receiver use narrowband modulations. In this paper a new architecture that allows incoherent detection of spread-spectrum signals is presented. A pseudorandom code generator ...
  • Steady state analysis of class-E amplifier with non-linear capacitor by means of discrete-time techniques 

    Águila López, Francisco del; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Giralt Mas, Ma. Rosa (The Institute of Electrical and Electronics Engineers, 2000)
    Text en actes de congrés
    Accés obert
    A new method to determine the steady state response of switched nonlinear circuits is proposed. The method is based on a Gear discretization of the circuit equations. Additional samples of the waveform are used to describe ...
  • Steady state analysis of Chua's circuit with RLCG transmission line 

    Bonet Dalmau, Jordi; Palà Schönwälder, Pere; Águila López, Francisco del (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    In this paper we present a new technique to compute the steady state response of nonlinear autonomous circuits with RLCG transmission lines. Using multipoint Pade approximants, instead of the commonly used expansions around ...
  • Modeling and robust low level control of an omnidirectional mobile robot 

    Comasòlivas Font, Ramon; Quevedo Casín, Joseba Jokin; Escobet Canal, Teresa; Escobet Canal, Antoni; Romera Formiguera, Juli (2017-04-01)
    Article
    Accés restringit per política de l'editorial
    This paper presents the modeling and robust low-level control design of a redundant mobile robot with four omnidirectional wheels, the iSense Robotic (iSRob) platform, that was designed to test safe control algorithms. ...

  • Energy dissipation in the presence of sub-harmonic excitation in dynamic atomic force microscopy 

    Chiesa, Matteo; Gadelrab, Karim Raafat; Verdaguer, Albert; Segura, Juan José; Barcons Xixons, Víctor; Thomson, Neil H.; Phillips, M.A.; Stefancich, M.; Santos Hernández, Sergio (2012-09)
    Article
    Accés obert
    Amplitude modulation atomic force microscopy allows quantifying energy dissipation in the nanoscale with great accuracy with the use of analytical expressions that account for the fundamental frequency and higher harmonics. ...
