  • Introducing semi-open learning/teaching into fundamental programming subjects 

    Xhafa Xhafa, Fatos; Marco Gómez, Jordi; Vázquez Alcocer, Pere Pau (Universitat de Barcelona. Edicions i Publicacions, 2006)
    Text en actes de congrés
    Accés obert
    Due to the development of Internet applications, semi-open learning is increasingly being introduced into traditional face-to-face learning and teaching. In several engineering degrees many subjects are developed using a ...
  • On zero-one and convergence laws for graphs embeddable on a fixed surface 

    Atserias, Albert; Kreutzer, Stephan; Noy Serrano, Marcos (Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2018)
    Text en actes de congrés
    Accés obert
    We show that for no surface except for the plane does monadic second-order logic (MSO) have a zero-one-law - and not even a convergence law - on the class of (connected) graphs embeddable on the surface. In addition we ...
  • A hierarchical mathematical model for automatic pipelining and allocation using elastic systems 

    Cortadella, Jordi; Petit Silvestre, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Text en actes de congrés
    Accés obert
    The advent of FPGA-based accelerators has encouraged the use of high-level synthesis (HLS) for rapid prototyping and design space exploration. In this context, design optimization at behavioral level becomes a critical ...
  • A quality control method for fraud detection on utility customers without an active contract 

    Coma Puig, Bernat; Carmona Vargas, Josep (Association for Computing Machinery (ACM), 2018)
    Text en actes de congrés
    Accés obert
    Fraud detection in energy consumption has proven to be a difficult problem for current techniques. In general, the approaches used in this area are restricted to compute a fraud score for each client based on its behaviour. ...
  • Clique is hard on average for regular resolution 

    Atserias, Albert; Bonacina, Ilario; Rezende, Susanna F. de; Lauria, Massimo; Nordström, Jakob; Razborov, Alexander (Association for Computing Machinery (ACM), 2018)
    Text en actes de congrés
    Accés obert
    We prove that for k ≪4√n regular resolution requires length nΩ(k) to establish that an Erdős–Rényi graph with appropriately chosen edge density does not contain a k-clique. This lower bound is optimal up to the multiplicative ...
  • Fixed partial match queries in quadtrees 

    Duch Brown, Amalia; Lau Laynes-Lozada, Gustavo Salvador; Martínez Parra, Conrado (Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2018)
    Text en actes de congrés
    Accés obert
    Several recent papers in the literature have addressed the analysis of the cost P_{n,q} of partial match search for a given fixed query q - that has s out of K specified coordinates - in different multidimensional data ...
  • On deletions in open addressing hashing 

    Jiménez Gómez, Rosa María; Martínez Parra, Conrado (Society for Industrial and Applied Mathematics (SIAM), 2018)
    Text en actes de congrés
    Accés obert
    Deletions in open addressing tables have often been seen as problematic. The usual solution is to use a special mark’deleted’ so that probe sequences continue past deleted slots, as if there was an element still sitting ...
  • Ordocoordinación: cómo organizar 700 estudiantes en un nuevo campus (y no morir en el intento) 

    Castro Rabal, Jorge; Farreres de la Morena, Xavier; Gabarró Vallès, Joaquim; Nivela Alós, M. Pilar Brígida; Pérez Poch, Antoni; Pino Blanco, Elvira; Rivero Almeida, José Miguel (Asociación de Enseñantes Universitarios de la Informática (AENUI), 2018)
    Text en actes de congrés
    Accés obert
    Since Autumn Term 2017 the Department of Computer Science of the Universitat Politecnica de Catalunya UPC-BarcelonaTech is in charge of teaching ”Fundamentals of Programming” in the new DiagonalBeso ´s Campus, at EEBE ...
  • Challenges and opportunities of applying natural language processing in business process management 

    van der Aa, Han; Carmona Vargas, Josep; Leopold, Henrik; Mendling, Jan; Padró, Lluís (Association for Computational Linguistics, 2018)
    Comunicació de congrés
    Accés obert
    The Business Process Management (BPM) field focuses in the coordination of labor so that organizational processes are smoothly executed in a way that products and services are properly delivered. At the same time, NLP has ...
  • NLP4BPM : Natural language processing tools for business process management 

    Delicado Alcántara, Luis; Sánchez Ferreres, Josep; Carmona Vargas, Josep; Padró, Lluís (2017)
    Text en actes de congrés
    Accés obert
    Business Process Management is facing a drift in the way process information is used within an organization. To reach a wide audience, organizations keep parallel representations of process information, thus making the ...
  • MPLS traffic engineering in satellite networks 

    Durresi, Arjan; Durresi, Mimoza; Barolli, Leonard; Xhafa Xhafa, Fatos (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Text en actes de congrés
    Accés obert
    Broadband satellite constellation networks will be required to carry all types of IP traffic, real time interactive traffic as well as non-real time traffic, warranting the need for appropriate QoS for these different ...
  • Using a grid platform for enabling real time user modeling in on-line campus 

    Caballé Llobet, Santiago; Xhafa Xhafa, Fatos; Daradoumis, Thanasis; Esteve, Joana; Barolli, Leonard; Durresi, Arjan (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Text en actes de congrés
    Accés obert
    User modelling in on-line distance learning is an important research field focusing on two important aspects: describing and predicting students' actions and intentions as well as adapting the learning process to students' ...
