    • openAccess   Association of physical activity with muscular strength and fat free mass in adolescents; The HELENA Study 

      Moliner-Urdiales, Diego; Ortega, Francisco B.; Vicente Rodríguez, Germán; Rey López, Juan P.; Gracia Marco, Luis; Widhalm, Kurt; Sjöstrom, Michael; Moreno, Luis A.; Castillo, Manuel J.; Ruiz, Jonatan R. Springer Verlag (2010)
      Objective: To analyze the association of objectively assessed physical activity (PA) with muscular strength and fat free mass in adolescents, and to determine whether meeting the current PA recommendations is associated ...

    • openAccess   Automated milling path tracking and CAM-Rob intergration for industrial redundant manipulators 

      Gracia Marco, Luis; Andres-Esperanza, Javier; Gracia, Carlos In-Tech (2012)
      The present paper explores the industrial capabilities of a CAM‐ROB system implementation based on a commercial CAD/CAM system (NXTM) for an industrial robotic workcell of eight joints, committed to the rapid prototyping ...

    • closedAccess   Calibration and control of a redundant robotic workcell for milling tasks 

      Andres-Esperanza, Javier; Gracia Marco, Luis; Tornero, Josep Taylor & Francis (2011)
      This article deals with the tuning of a complex robotic workcell of eight joints devoted to milling tasks. It consists of a KUKA™ manipulator mounted on a linear track and synchronised with a rotary table. Prior to any ...

    • closedAccess   CAM-Rob postprocessor based on a fuzzified redundancy resolution scheme 

      Andres-Esperanza, Javier; Gracia Marco, Luis; Tornero, Josep Springer-Verlag (2012)
      This work highlights the applicability of different redundancy resolution schemes to the postprocessing stage from a computer-aided manufacturing (CAM) system to an industrial redundant workcell. The inverse kinematic ...

    • openAccess   Epidemiology of injuries in First Division Spanish football 

      Noya Salces, Javier; Gómez Carmona, Pedro M.; Gracia Marco, Luis; Moliner-Urdiales, Diego; Sillero Quintana, Manuel Taylor & Francis (2014-05)
      The aim was to examine the injuries sustained by Spanish football players in the First Division and to compare injury-related variables in the context of both competition and training. The injury data were prospectively ...

    • closedAccess   Implementation and testing of a CAM postprocessor for an industrial redundant workcell with evaluation of several fuzzified Redundancy Resolution Schemes 

      Andres-Esperanza, Javier; Gracia Marco, Luis; Tornero, Josep Elsevier (2011)
      This paper describes the implementation of a postprocessor to adapt the toolpath generated by a CAM system (NXTM) to a complex workcell of eight joints (namely, a KUKA KR15/2 manipulator mounted on a linear track and ...

    • openAccess   The on-line teaching of robot visual servoing 

      Pérez Vidal, Carlos; García, Nicolás; Cervera, Enric; Gracia Marco, Luis; Sabater, José María Manchester University Press (2011)
      Visual servoing uses the visual information provided by cameras to control the movement of a robotic system. This paper presents an international on-line course aimed at BSc, MSc and PhD students in this subject. The ...

    • 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 ...
