    This paper presents the optimal batch scheduling of a multi-product dairy process using an approach that combines optimization and constraint programming techniques. A suitable model describing the subprocesses and production ...
  • A discrete-time technique for the steady-state analysis of nonlinear class-E amplifiers 

    Águila López, Francisco del; Palà Schönwälder, Pere; Molina Gaudó, Pilar; Mediano Heredia, Arturo (Institute of Electrical and Electronics Engineers (IEEE), 2007-06-11)
    Article
    Open Access
    Switched circuits are widely used, particularly for power electronic applications in which efficiency is important. Of these applications, the class-E amplifier has been given particular attention, since it is theoretically ...
  • 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
    Open Access
    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 discrete-time approach to the steady-state and stability analysis of distributed nonlinear autonomous circuits 

    Bonet Dalmau, Jordi; Palà Schönwälder, Pere (2000-02)
    Article
    Open Access
    We present a direct method for the steady-state and stability analysis of autonomous circuits with transmission lines and generic non- linear elements. With the discretization of the equations that describe the circuit ...
