    • DynAlloy analyzer: a tool for the specification and analysis of Alloy models with dynamic behaviour 

      Regis, Germán; Cornejo, César; Gutiérrez Brida, Simón; Politano, Mariano; Raverta, Fernando; Ponzio, Pablo; Aguirre, Nazareno; Galeotti, Juan Pablo; Frías, Marcelo (2017-09)
      "We describe DynAlloy Analyzer, a tool that extends Alloy Analyzer with support for dynamic elements in Alloy models. The tool builds upon Alloy Analyzer in a way that makes it fully compatible with Alloy models, and extends ...
    • EEG waveform analysis of P300 ERP with applications to brain computer interfaces 

      Ramele, Rodrigo; Villar, Ana Julia; Santos, Juan Miguel (2018-11)
      "The Electroencephalography (EEG) is not just a mere clinical tool anymore. It has become the de-facto mobile, portable, non-invasive brain imaging sensor to harness brain information in real time. It is now being used to ...
    • Effcient analytical queries on semantic web cata cubes 

      Etcheverry, Lorena; Vaisman, Alejandro Ariel (2017-12)
      "The amount of multidimensional data published on the semantic web (SW) is constantly increasing, due to initiatives such as Open Data and Open Government Data, among other ones. Models, languages, and tools, that allow ...
    • Foundations and applications for secure triggers 

      Futoransky, Ariel; Kargieman, Emiliano; Sarraute, Carlos; Waissbein, Ariel (2005)
      "Imagine there is certain content we want to maintain private until some particular event occurs, when we want to have it automatically disclosed. Suppose furthermore, that we want this done in a (possibly) malicious host. ...
    • The geodesic distance between 𝒢I0 models and its application to region discrimination 

      Naranjo-Torres, José; Gambini, Juliana; Frery, Alejandro C. (2017-03)
      "The 𝒢I0 distribution is able to characterize different regions in monopolarized SAR imagery. It is indexed by three parameters: the number of looks (which can be estimated in the whole image), a scale parameter, and a ...
    • Histogram of gradient orientations of signal plots applied to P300 detection 

      Ramele, Rodrigo; Villar, Ana Julia; Santos, Juan Miguel (2019)
      "The analysis of Electroencephalographic (EEG) signals is of ulterior importance to aid in the diagnosis of mental disease and to increase our understanding of the brain. Traditionally, clinical EEG has been analyzed in ...
    • An inference engine based on fuzzy logic for uncertain and imprecise expert reasoning 

      D'Aquila, Raimundo O.; Crespo Crespo, Cecilia; Mate, J. L.; Pazos, J. (2002)
      "This paper addresses the development and computational implementation of an inference engine based on a full fuzzy logic, excluding only imprecise quantifiers, for handling uncertainty and imprecision in rule-based expert ...
    • Learning by knowledge sharing in autonomous intelligent systems 

      García-Martínez, Ramón; Borrajo, Daniel; Maceri, Pablo; Britos, Paola Verónica (2006)
      "Very few learning systems applied to problem solving have focused on learning operator definitions from the interaction with a completely unknown environment. In order to achieve better learning convergence, several agents ...
    • Mobility data warehouses 

      Vaisman, Alejandro Ariel; Zimányi, Esteban (2019)
      "The interest in mobility data analysis has grown dramatically with the wide availability of devices that track the position of moving objects. Mobility analysis can be applied, for example, to analyze traffic flows. To ...
    • Pedestrian collective motion in competitive room evacuation 

      Garcimartín, Ángel; Pastor, José Martín; Martín-Gómez, César; Parisi, Daniel R.; Zuriguel, Iker (2017-12)
      "When a sizable number of people evacuate a room, if the door is not large enough, an accumulation of pedestrians in front of the exit may take place. This is the cause of emerging collective phenomena where the density ...
    • Piet: a GIS-OLAP implementation 

      Vaisman, Alejandro Ariel; Gómez, Leticia Irene; Kuijpers, Bart; Escribano, Ariel (2007)
      "Data aggregation in Geographic Information Systems (GIS) is a desirable feature, although only marginally present in commercial systems, which also fail to provide integration between GIS and OLAP (On Line Analytical ...
    • Quaternions and dual quaternions: singularity-free multirobot formation control 

      Mas, Ignacio; Kitts, Christopher (2017-09)
      "Cluster space control is a method of multirobot formation keeping that considers a group of robots to be a single entity, defining state variables to represent characteristics of the group, such as position, orientation, ...
    • Sampling from the 𝒢I0 distribution 

      Chan, Debora; Rey, Andrea; Gambini, Juliana; Frery, Alejandro C. (2018-12)
      "Synthetic Aperture Radar (SAR) images are widely used in several environmental applications because they provide information which cannot be obtained with other sensors. The 𝒢I0 distribution is an important model for ...
