    • A web-based filtering engine for understanding event specifications in large conceptual schemas 

      Villegas Niño, Antonio; Olivé Ramon, Antoni; Sancho Samsó, María Ribera (Springer, 2012)
      Comunicació de congrés
      Accés obert
      A complete conceptual schema must include all relevant general static and dynamic aspects of an information system. Event types describe a nonempty set of allowed changes in the population of entity or relationship types ...

    • Filter optimization in SDN-based flexgrid networks 

      Paolucci, Francesco; Fresi, Francesco; Castro Casales, Alberto; Velasco Esteban, Luis Domingo; Cugini, Filippo; Sambo, Nicola; Giorgetti, Alessio; Poti, Luca; Castoldi, Piero (Optical Society of American (OSA), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The novel super-filter technique for flexgrid optical networks is proposed to compact spectrum-contiguous lightpaths. The technique is applied in a specifically extended SDN architecture, showing significant gains in terms ...

    • Improving the energy efficiency of hardware-assisted watchpoint systems 

      Karakostas, Vasileios; Tomić, Saša; Unsal, Osman Sabri; Nemirovsky, Mario; Cristal Kestelman, Adrián (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Hardware-assisted watchpoint systems enhance the execution of numerous dynamic software techniques, such as memory protection, module isolation, deterministic execution, and data race detection. In this paper, we show ...

    • Local isotropy indicator for SAR image filtering: application to Envisat/ASAR images of the Doñana Wetland 

      Martí Cardona, Belén; López Martínez, Carlos; Dolz Ripollès, Josep (2015-04)
      Article
      Accés obert
      This paper explores a geometrical and computationally simple operator, named Ds, for local isotropy assessment on SAR images. It is assumed that isotropic intensity distributions in natural areas, either textured or ...

    • Multiple tone interferers in an FH-MFSK spread spectrum communication system 

      Agustí Comes, Ramon (Institute of Electrical and Electronics Engineers (IEEE), 1984)
      Text en actes de congrés
      Accés obert
      An analysis of the effect of multiple tone interferers on the bit error rate in a Frequency-Hopped Multiple Frequency Shift Keying (FH-MFSK) spread spectrum communication is given. A constant insertion rate de tection ...

    • Object tracking in a rearward looking Radar 

      Bakkari, Hamza (Universitat Politècnica de Catalunya, 2011-06-02)
      Projecte/Treball Final de Carrera
      Accés restringit per decisió de l'autor
      Català: Continental desenvolupa sistemes avançats d´assistència als conductors. Un dels més aplicats és el Control adaptable de velocitat o Adaptive cruise control (ACC). El sistema ACC permet seguir el vehicles al ...

    • orsum: a Python package for filtering and comparing enrichment analyses using a simple principle 

      Ozisik, Ozan; Térézol, Morgane; Baudot, Anaïs (BioMed Central (BMC), 2022)
      Article
      Accés obert
      BACKGROUND: Enrichment analyses are widely applied to investigate lists of genes of interest. However, such analyses often result in long lists of annotation terms with high redundancy, making the interpretation and ...

    • Sensor-Aware Filtering, representation and Completion of 3D Scans 

      Comino Trinidad, Marc (Universitat Politècnica de Catalunya, 2015-07-08)
      Projecte Final de Màster Oficial
      Accés obert
      In this work we address different problems related with the representation, registration, filtering and visualization of point-based 3D models. As test case, we will use a 3.5 billion points data set that resulted from 3D ...

    • Superfilter technique in SDN-controlled elastic optical networks 

      Paolucci, Francesco; Cugini, Filippo; Fresi, Francesco; Meloni, Gianluca; Giorgetti, Alessio; Sambo, Nicola; Poti, Luca; Castro Casales, Alberto; Velasco Esteban, Luis Domingo; Castoldi, Piero (Institute of Electrical and Electronics Engineers (IEEE), 2015-02-01)
      Article
      Accés restringit per política de l'editorial
      In flexigrid elastic optical networks, filtering cascade effects strongly affect the overall transmission performance. To avoid these detrimental impairments, each lightpath is typically configured, in an independent way, ...

    • Three-element filtering antenna array designed by the equivalent circuit approach 

      Kufa, Martin; Raida, Zbynek; Mateu Mateu, Jordi (2016-09-01)
      Article
      Accés obert
      This paper introduces a design methodology of a third-order three-element patch array that has no filtering parts and yet behaves like a filtering antenna (filtenna). The design approach includes shaping the frequency ...

    • Total estimation from RGB video: on-line camera self-calibration, non-rigid shape and motion
