    • closedAccess   Variable-size batched Gauss–Jordan elimination for block-Jacobi preconditioning on graphics processors 

      Anzt, Hartwig; Dongarra, Jack; Flegar, Goran; Quintana-Orti, Enrique S. Elsevier (2019)
      In this work, we address the efficient realization of block-Jacobi preconditioning on graphics processing units (GPUs). This task requires the solution of a collection of small and independent linear systems. To fully ...

    • openAccess   Visialization of Ontologies to Specify Semantic Descriptions Of Services 

      Tomás López, Vicente Ramón; Samper, J. Javier; Carrillo, Eduardo; Do Nascimento, Rogério P. C. IEEE Computer Society (2008)
      The present paper describes the main characteristics and components of a tool developed for integrating the definition of profiles for semantic Web Services. This tool is based on the languages DAML-S and OWL-S. It ...

    • openAccess   Vision for Robust Robot Manipulation 

      Martínez Martín, Ester; del Pobil, Angel P. MDPI (2019)
      Advances in Robotics are leading to a new generation of assistant robots working in ordinary, domestic settings. This evolution raises new challenges in the tasks to be accomplished by the robots. This is the case for ...

    • openAccess   Vision-based grasp tracking for planar objects 

      Recatalá Ballester, Gabriel; Carloni, Raffaella; Melchiorri, Claudio; Sanz, Pedro J; Cervera, Enric; del Pobil, Angel P. IEEE Systems, Man, and Cybernetics Society (2008)
      In robotics, the manipulation of a priori unknown objects involves several steps and problems that must be carefully considered and solved by proper planning and control algorithms. For example, once suitable contact ...

    • closedAccess   Visual control of robots with delayed images 

      Pérez Vidal, Carlos; Gracia Marco, Luis; García, Nicolás; Cervera, Enric Brill (2009)
      This research develops a control scheme for visual servoing that explicitly takes into account the delay in- troduced by image acquisition and processing. For this purpose, a predictor block, i.e., an estimator that predicts ...

    • closedAccess   Visual control through narrow passages for an omnidirectional wheeled robot 

      Morra, Damiano; Cervera, Enric; Buonocore, Luca Rosario; Cacace, Jonathan; Ruggiero, Fabio; Lippiello, Vincenzo; Di Castro, Mario IEEE (2022)
      Robotic systems are gradually replacing human intervention in dangerous facilities to improve human safety and prevent risky situations. In this domain, our work addresses the problem of autonomous crossing narrow ...

    • openAccess   Visually-Guided Manipulation Techniques for Robotic Autonomous Underwater Panel Interventions 

      Peñalver Monfort, Antonio; Pérez Soler, Javier; Fernández Fresneda, José Javier; Sales Gil, Jorge; Sanz, Pedro J; García Sánchez, Juan Carlos; Fornas Garcia, David; Marin, Raul Elsevier (2015)
      The long term of this ongoing research has to do with increasing the autonomy levels for underwater intervention missions. Bearing in mind that the speci c mission to face has been the intervention on a panel, in this paper ...

    • openAccess   What Role Can Process Mining Play in Recurrent Clinical Guidelines Issues? A Position Paper 

      GATTA, Roberto; Vallati, Mauro; Fernandez-Llatas, Carlos; Martinez-Millana, Antonio; orini, stefania; SACCHI, LUCIA; Lenkowicz, Jacopo; Marcos, Mar; Munoz-Gama, Jorge; Cuendet, Michael A.; Bari, Berardino de; Marco-Ruiz, Luis; Stefanini, Alessandro; Valero-Ramon, Zoe; Michielin, Olivier; Lapinskas, Tomas; Montvila, Antanas; Martin, Niels; Tavazzi, Erica; Castellano, Maurizio MDPI (2020-09-11)
      In the age of Evidence-Based Medicine, Clinical Guidelines (CGs) are recognized to be an indispensable tool to support physicians in their daily clinical practice. Medical Informatics is expected to play a relevant role ...

    • openAccess   When Humanoid Robots Become Human-Like Interaction Partners: Corepresentation of Robotic Actions 

      del Pobil, Angel P.; Tirado Bou, María Desamparados; Stenzel, Anna; Chinellato, Eris; Lappe, Markus; Liepelt, Roman American Psychological Association (2012)
      In human-human interactions co-representing a partner’s actions is crucial to successfully adjust and coordinate actions with others. Current research suggests that action co-representation is restricted to interactions ...
