  • The polysemy of the words that children learn over time 

    Casas Fernández, Bernardino; Catala Roig, Neus; Ferrer Cancho, Ramon; Hernández Fernández, Antonio; Baixeries i Juvillà, Jaume (2018-12)
    Article
    Accés obert
    Here we study polysemy as a potential learning bias in vocabulary learning in children. We employ a massive set of transcriptions of conversations between children and adults in English, to analyze the evolution of mean ...
  • The octahedron abstract domain 

    Clarisó Viladrosa, Robert; Cortadella, Jordi (Springer, 2004)
    Text en actes de congrés
    Accés obert
    An interesting area in static analysis is the study of numeric properties. Complex properties can be analyzed using abstract interpretation, provided that an adequate abstract domain is defined. Each domain can represent ...
  • A case study for the verification of complex timed circuits: IPCMOS 

    Peña Basurto, Marco Antonio; Cortadella, Jordi; Pastor Llorens, Enric; Smirnov, Alexandre (Institute of Electrical and Electronics Engineers (IEEE), 2002)
    Text en actes de congrés
    Accés obert
    The verification of a n-stage pulse-driven IPCMOS pipeline, for any n>0, is presented. The complexity of the system is 32n transistors and delay information is provided at the level of transistor The correctness of the ...
  • Logic design of asynchronous circuits 

    Cortadella, Jordi; Yakovlev, Alex; Garside, Jim (Institute of Electrical and Electronics Engineers (IEEE), 2002)
    Text en actes de congrés
    Accés obert
    Summary form only given. This tutorial aims at motivating the audience to consider asynchronous circuits as a competitive alternative to solve some of the design problems inherent to submicron technologies. One of the main ...
  • Multiview: a software package for multiview pattern recognition methods 

    Kanaan Izquierdo, Samir; Ziyatdinov, Andrey; Burgueño, Maria Araceli; Perera Lluna, Alexandre (2018-12-31)
    Article
    Accés obert
    Multiview datasets are the norm in bioinformatics, often under the label multi-omics. Multiview data is gathered from several experiments, measurements or feature sets available for the same subjects. Recent studies in ...
  • Formal verification of safety properties in timed circuits 

    Peña Basurto, Marco Antonio; Cortadella, Jordi; Kondratyev, Alex; Pastor Llorens, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Text en actes de congrés
    Accés obert
    The incorporation of timing makes circuit verification computationally expensive. This paper proposes a new approach for the verification of timed circuits. Rather than calculating the exact timed stare space, a conservative ...
  • A radix-16 SRT division unit with speculation of the quotient digits 

    Gianluca, Cornetta; Cortadella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    The speed of a divider based on a digit-recurrence algorithm depends mainly on the latency of the quotient digit generation function. In this paper we present an analytical approach that extends the theory developed for ...
  • Behavioral transformations to increase the noise immunity of asynchronous specifications 

    Taubin, Alexander; Kondratyev, Alex; Cortadella, Jordi; Lavagno, Luciano (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    Noise immunity is becoming one of the most important design parameters for deep-sub-micron (DSM) technologies. Asynchronous circuits seem to be a good candidate to alleviate the problems originated by simultaneous switching ...
  • Combining structural and symbolic methods for the verification of concurrent systems 

    Cortadella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Text en actes de congrés
    Accés obert
    The contributions during the last few years on the structural theory of Petri nets can now be applied to formal verification. The structural theory provides methods to find efficient encoding schemes for symbolic representations ...
  • Structural methods to improve the symbolic analysis of Petri nets 

    Pastor Llorens, Enric; Cortadella, Jordi; Peña Basurto, Marco Antonio (Springer, 1999)
    Text en actes de congrés
    Accés obert
    Symbolic techniques based on BDDs (Binary Decision Diagrams) have emerged as an efficient strategy for the analysis of Petri nets. The existing techniques for the symbolic encoding of each marking use a fixed set of variables ...
  • Synthesis of asynchronous control circuits with automatically generated relative timing assumptions 

    Cortadella, Jordi; Kishinevsky, Michael; Burns, Steven M.; Stevens, Kenneth S. (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    This paper describes a method of synthesis of asynchronous circuits with relative timing. Asynchronous communication between gates and modules typically utilizes handshakes to ensure functionality. Relative timing assumptions ...
  • What is the cost of delay insensitivity? 

    Saito, Hiroshi; Kondratyev, Alex; Cortadella, Jordi; Lavagno, Luciano; Yakovlev, Alex (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    Deep submicron technology calls for new design techniques, in which wire and gate delays are accounted to have equal or nearly equal effect on circuit behaviour. Asynchronous speed-independent (SI) circuits, whose behaviour ...
