  • De Menos a Distinto: Estudio de la Implantación de R en las asignaturas del grado de estadística 

    Baixeries i Juvillà, Jaume; Fairén González, Marta; Gabarró Vallès, Joaquim; Pasarella Sánchez, Ana Edelmira (2016)
    Conference report
    Open Access
    Teaching computer science in degrees that are not computer science related presents an important challenge: to motivate the students and to achieve good average grades. The student’s complaint is always based ...
  • Incorporating negative information in process discovery 

    Ponce de León, Hernán; Carmona Vargas, Josep; vanden Broucke, Seppe (Springer, 2015)
    Conference report
    Restricted access - publisher's policy
    The discovery of a formal process model from event logs describing real process executions is a challenging problem that has been studied from several angles. Most of the contributions consider the extraction of a model ...
  • Log-based simplification of process models 

    San Pedro Martín, Javier de; Carmona Vargas, Josep; Cortadella Fortuny, Jordi (Springer, 2015)
    Conference report
    Open Access
    The visualization of models is essential for user-friendly human-machine interactions during Process Mining. A simple graphical representation contributes to give intuitive information about the behavior of a system. ...
  • Can frogs find large independent sets in a decentralized way? Yes they can! 

    Blum, Christian; Blesa Aguilera, Maria Josep; Calvo, Borja (Springer, 2014)
    Conference report
    Open Access
    The problem of identifying a maximal independent (node) set in a given graph is a fundamental problem in distributed computing. It has numerous applications, for example, in wireless networks in the context of facility ...
  • Reactive clocks with variability-tracking jitter 

    Cortadella Fortuny, Jordi; Lavagno, Luciano; López Muñoz, Pedro; Lupon Navazo, Marc; Moreno Vega, Alberto; Roca Pérez, Antoni; Sapatnekar, Sachin S. (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    The growing variability in nanoelectronic devices, due to uncertainties from the manufacturing process and environmental conditions (power supply, temperature, aging), requires increasing design guardbands, forcing circuits ...
  • Uncertainty in the cloud: an angel-daemon approach to modelling performance 

    Stewart, Alan; Gabarró Vallès, Joaquim; Keenan, Anthony (Springer, 2015)
    Conference report
    Open Access
    Uncertainty profiles are used to study the effects of contention within cloud and service-based environments. An uncertainty profile provides a qualitative description of an environment whose quality of service (QoS) may ...
  • Linked data and linked APIs: similarities, differences, and challenges 

    Verborgh, Ruben; Steiner, Thomas; Van de Walle, Rik; Gabarró Vallès, Joaquim (Springer, 2012)
    Conference report
    Open Access
    In an often retweeted Twitter post, entrepreneur and software architect Inge Henriksen described the relation of Web 1.0 to Web 3.0 as: “Web 1.0 connected humans with machines. Web 2.0 connected humans with humans. Web 3.0 ...
  • A hierarchical approach for generating regular floorplans 

    San Pedro Martín, Javier de; Cortadella Fortuny, Jordi; Roca Pérez, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    The complexity of the VLSI physical design flow grows dramatically as the level of integration increases. An effective way to manage this increasing complexity is through the use of regular designs which contain more ...
  • POD: A tool for process discovery using partial orders and independence information 

    Ponce de León, Hernán; Rodríguez, César; Carmona Vargas, Josep (CEUR-WS.org, 2015)
    Conference report
    Open Access
    Current process discovery techniques focus on the derivation of a process model on the basis of the activity relations extracted from an event log. However, there are situations where more knowledge can be provided to ...
  • Unfolding-based process discovery 

    Ponce de León, Hernán; Rodríguez, César; Carmona Vargas, Josep; Heljanko, Keijo; Haar, Stefan (Springer, 2015)
    Conference report
    Restricted access - publisher's policy
    This paper presents a novel technique for process discovery. In contrast to the current trend, which only considers an event log for discovering a process model, we assume two additional inputs: an independence relation ...
