    "Imagine there is certain content we want to maintain private until some particular event occurs, when we want to have it automatically disclosed. Suppose furthermore, that we want this done in a (possibly) malicious host. ...
  • Learning by knowledge sharing in autonomous intelligent systems 

    García-Martínez, Ramón; Borrajo, Daniel; Maceri, Pablo; Britos, Paola Verónica (2006)
    "Very few learning systems applied to problem solving have focused on learning operator definitions from the interaction with a completely unknown environment. In order to achieve better learning convergence, several agents ...
  • An extension of LaSalle’s Invariance Principle for switched systems

    "This paper addresses invariance principles for a certain class of switched nonlinear systems. We provide an extension of LaSalle’s Invariance Principle for these systems and state asymptotic stability criteria. We also ...
  • Uncertainty relation for the optimization of optical-fiber transmission systems simulations 

    Tolisano, T.; Callegari, F. A.; Grosz, Diego; Fragnito, H.; Rieznik, Andrés (2005)
    “The mathematical inequality which in quantum mechanics gives rise to the uncertainty principle between two non commuting operators is used to develop a spatial step-size selection algorithm for the Split-Step Fourier ...
  • Stochastic resonance and Brownian ratchets 

    Fendrik, Alejandro; Romanelli, Lilia; Perazzo, Roberto P. J. (2005)
    "We discuss the connections between Brownian ratchets (BR) and stochastic resonance (SR). We consider a periodic potential energy landscape with no left–right symmetry that is driven by an external force which can be ...
  • Order and disorder in the local evolutionary minority game 

    Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J. (2005)
    "We study a modification of the Evolutionary Minority Game (EMG) in which agents are placed in the nodes of a regular or a random graph.A neighborhood for each agent can thus be defined and a modification of the usual ...
  • The evolutionary minority game with local coordination 

    Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J. (2003)
    "We discuss a modi-cation of the evolutionary minority game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be de-ned and a modi-cationof the usual ...
  • An inference engine based on fuzzy logic for uncertain and imprecise expert reasoning 

    D'Aquila, Raimundo O.; Crespo, C.; Mate, J. L.; Pazos, J. (2002)
    "This paper addresses the development and computational implementation of an inference engine based on a full fuzzy logic, excluding only imprecise quantifiers, for handling uncertainty and imprecision in rule-based expert ...
  • Optimal control of a batch bioreactor: a study on the use of an imperfect model 

    Dondo, Rodolfo G.; Marqués, Dardo (2001)
    "This paper presents a numerical study on the performance degradation of a batch bioreactor optimal control strategy when the model used to compute such strategy shows wide variations from the real process. The optimal ...
