    • UCTx: a multi-agent system to assist a transplant coordination unit 

      Cortés García, Claudio Ulises; Vázquez Salceda, Javier; López-Navidad, Antonio; Caballero, Francisco (2001-04-03)
      Report de recerca
      Accés obert
      We present a system called UCTx, designed to model and automate some of the tasks performed by a Transplant Coordination Unit (UCTx) inside a Hospital. The aim of this work is to show how a multi-agent approach allows ...
    • The ICTA-ICP Rooftop Greenhouse Lab (RTG-Lab): closing metabolic flows (energy, water, CO2) through integrated Rooftop Greenhouses 

      Sanyé-Mengual, E.; Llorach Massana, Pere; Sanjuan Demás, David; Oliver-Solà, Jordi; Josa Garcia-Tornel, Alejandro; Montero, Juan Ignacio; Rieradevall Pons, Joan (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The ICTA-ICP Rooftop Greenhouse Lab (RTG-Lab) is a research-oriented RTG situated in the UAB Campus (Bellaterra, Barcelona). In contrast to current RTGs, the RTG-Lab integrates energy, water and CO2 flows into the building’s ...
    • Adaptive us-mrac for disturbance cancellation 

      Bertran Albertí, Eduardo; Montoro López, Gabriel (Institution of Electrical Engineers, 1995-01)
      Article
      Accés obert
      A variable structure, model reference adaptive control (VS-MRAC) devoted to cancel interferences without the requirement of an auxiliary input is proposed. This method is an improved alternative to the strategies recently ...
    • Two-dimensional solitons with second-order nonlinearities 

      Torner Sabata, Lluís; Menyuk, Curtis; Torruellas, William; Stegeman, George (1995-01)
      Article
      Accés restringit per política de l'editorial
      We investigate the propagation of intense Gaussian beams in materials with quadratic nonlinearity. Excitation of (2 + 1) solitons is numerically predicted at finite phase mismatch and in the presence of linear walk-off ...
    • Sample cumulants of stationary processes: asymptotic results 

      Rodríguez Fonollosa, José Adrián (1995-04)
      Article
      Accés obert
      In this paper, we present the formulas of the covariances of the second-, third-, and fourth-order sample cumulants of stationary processes. These expressions are then used to obtain the analytic performance of FIR system ...
    • Bright solitons with second-order nonlinearities 

      Torner Sabata, Lluís; Menyuk, Curtis; Stegeman, George (1995-05)
      Article
      Accés restringit per política de l'editorial
      We investigate the mutual trapping of intense fundamental and second-harmonic waves propagating in materials with second-order nonlinearity. Consistent with Menyuk’s robustness hypothesis of solitons, we numerically observe ...
    • Potentials of mean force in acidic proton transfer reactions in constrained geometries 

      Martí Rabassa, Jordi (2016-10-17)
      Article
      Accés restringit per política de l'editorial
      Free energy barriers associated with the transfer of an excess proton in water and related to the potentials of mean force in proton transfer episodes have been computed in a wide range of thermodynamic states, from ...
    • Obtención de datos e imágenes ers-1 mediante simulación. Aplicaciones a interferometría 

      Carrasco, D.; Rosich, B.; Alonso, J.; Broquetas Ibars, Antoni (1995-06)
      Article
      Accés obert
      La simulación de imágenes SAR nos permite comprender algunas características de los sistemas SAR y comprobar la calidad de los algoritmos de procesado de imágenes SAR. En este artículo se presenta un simulador de señales ...
    • Region-based video coding using mathematical morphology 

      Salembier Clairon, Philippe Jean; Torres Urgell, Lluís; Meyer, F; Gu, C (1995-06)
      Article
      Accés obert
      This paper presents a region-based coding algorithm for video sequences. The coding approach involves a time-recursive segmentation relying on the pixels homogeneity, a region-based motion estimation, and motion compensated ...
    • Image restoracion using the w-slice method 

      Sayrol Clols, Elisa; Chrysostomos, Nikias; Gasull Llampallas, Antoni (1995-08)
      Article
      Accés obert
      We propose the use of higher order statistics (HOS)-based methods to address the problem of image restoration. The restoration strategy is based on the fact that the phase information of the original image and its HOS are ...
