  • 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 ...
  • A method for assessing parameter impact on control-flow discovery algorithms 

    Ribeiro, Joel; Carmona Vargas, Josep (CEUR-WS.org, 2015)
    Conference report
    Open Access
    Given an event log L, a control-flow discovery algorithm f, and a quality metric m, this paper faces the following problem: what are the parameters in f that mostly influence its application in terms of m when applied ...
  • Discovery of personal processes from labeled sensor data: An application of process mining to personalized health care 

    Sztyler, Timo; Völker, Johanna; Carmona Vargas, Josep; Meier, Oliver; Stuckenschmidt, Heiner (CEUR-WS.org, 2015)
    Conference report
    Open Access
    Currently, there is a trend to promote personalized health care in order to prevent diseases or to have a healthier life. Using current devices such as smart-phones and smart-watches, an individual can easily record detailed ...
  • Event log visualisation with conditional partial order graphs: from control flow to data 

    Mokhov, Andrey; Carmona Vargas, Josep (CEUR-WS.org, 2015)
    Conference report
    Open Access
    Process mining techniques rely on event logs: the extraction of a process model (discovery) takes an event log as the input, the adequacy of a process model (conformance) is checked against an event log, and the enhancement ...
