    Additive manufacturing (AM) has increased its field of application, not only for prototypes but also for final parts. Therefore, the need of study new materials is currently growing. This paper aims to study the effect of ...
  • Hand-eye calibration made easy through a closed-form two-stage method 

    Sarabandi, Soheil; Porta Pleite, Josep Maria; Thomas, Federico (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
    Open Access
    An analysis of the existing hand-eye calibration methods reveals that most of them are far from trivial. And, what is worse, their intrinsic complexity makes it difficult to elucidate under which circumstances they fail ...
  • Comparison between structural configurations designed by steel shear wall, moment resistant frame and X shape bracing systems
