    Descripción: ...The coatings with CrN/TiN 100 bilayers exhibited a wear volume two orders of magnitude lower than the single layer coatings of TiN and CrN. Mechanical properties were strongly influenced by the decrease of the modulation period thickness of the coatings, having increased from 23.1 GPa for the sample with 10 bilayers to 29.8 GPa for the sample with CrN / TiN 100 bilayers. ...

    Descripción: ...Abstract ─This research was aimed to develop a methodology for establishing the proper dimensions of a four-bar linkage prosthetic knee mechanism for maximum stability. Based on the fact that the stability of a four-bar knee during load-bearing is determined by the location of the instantaneous center of rotation (ICR) with respect to the ground reaction force (GRF) vector, a computational platform was developed to simulate the movement of the leg, the GRF vector and the position of the ICR of the mechanism. ...
