    • Fast analysis and optimization of sparsely distributed partial modification problems 

      Fang, Xiaoxing; Heldring, Alexander; Rius Casals, Juan Manuel; Cao, Qunsheng (Institute of Electrical and Electronics Engineers (IEEE), 2022-08)
      Article
      Accés obert
      This article addresses the efficient numerical analysis of sparsely distributed small modifications in a large structure, that is, the sparsely distributed partial modification problem (SDPMP). A hierarchical matrix ...

    • Iterative Learning Control for homing guidance design of missiles 

      Acho Zuppa, Leonardo (Elsevier, 2017-02-16)
      Article
      Accés obert
      This paper presents an Iterative Learning Control design applied to homing guidance of missiles against maneuvering targets. According to numerical experiments, although an increase of the control energies is appreciated ...

    • Nonlinear actuation model for lateral electrostatically-actuated DC-contact RF MEMS series switches. 

      Lázaro Guillén, Antoni; Girbau Sala, David; Pradell i Cara, Lluís; Nebot Serra, Àlvar (JOHN WILEY & SONS INC, 2007-06-01)
      Article
      Accés obert
      In this work, a nonlinear model to predict actuation characteristics in lateral electrostatically-actuated DC-contact MEMS switches is proposed. In this case a parallel-plate approximation cannot be applied. The model ...

    • On computational order of convergence of some multi-precision solvers of nonlinear systems of equations 

      Grau Sánchez, Miguel; Grau Gotés, Maria Àngela; Díaz Barrero, José Luis (2011-05-02)
      Report de recerca
      Accés obert
      In this paper the local order of convergence used in iterative methods to solve nonlinear systems of equations is revisited, where shorter alternative analytic proofs of the order based on developments of multilineal ...

    • Optimized query forgery for private information retrieval 

      Rebollo Monedero, David; Forné Muñoz, Jorge (2010-09)
      Article
      Accés obert
      We present a mathematical formulation for the optimization of query forgery for private information retrieval, in the sense that the privacy risk is minimized for a given traffic and processing overhead. The privacy ...

    • The Koch monopole: a small fractal antenna 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Cardama Aznar, Ángel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2000-11)
      Article
      Accés obert
      Fractal objects have some unique geometrical properties. One of them is the possibility to enclose in a finite area an infinitely long curve. The resulting curve is highly convoluted being nowhere differentiable. One such ...

    • Un esquema paralelo para el cálculo del pseudoespectro de matrices de gran magnitud 

      Otero Calviño, Beatriz; Astudillo, Reinaldo; Castillo, Zenaida (Universitat Politècnica de Catalunya. CIMNE, 2015-01-01)
      Article
      Accés obert
      El pseudoespectro es una gran herramienta para el estudio de sistemas dinámicos asociados a matrices no normales. En las últimas décadas su estudio y aplicación se ha intensificado, por lo que realizar su cálculo de forma ...
