A prosthetic foot is an important element of a prosthesis, although it is not always fully recognized that the properties of the foot, along with the prosthetic knee joint and the socket, are in part responsible for the stability and metabolic energy cost during walking. The stiffness and the hysteresis, which are the topics of this paper, are not properly prescribed, but could be adapted to im...
A parabolic PDE with hysteresis in the source term is considered. The existence of periodic solutions for a general hysteresis operator is proven and an asymptotic result for solutions of this equation, using ideas due to Krejč́ı, is obtained.
We use Hoffmann's suggestion [Hoffmann, G. W. (1986) J. Theor. Biol. 122, 33-67] of hysteresis in a single neuron level and determine its consequences in a synchronous network made of such neurons. We show that the overall retrieval ability in the presence of noise and the memory capacity of the network in the present model are better than in conventional models without such hysteresis. Second-...
Appendix (Supplementary Material) Appendix A. Experimental quantification of the ratedependence of indentation hysteresis of individual chondrocytes Freshly isolated cells were probed with the nanosized and micron-sized tips at indentation rates of 200nm/s, 500nm/s, 1μm/s, 3μm/s, and 5μm/s. The area enclosed by the hysteresis loop (e.g., Fig. 6) is related to the strain energy dissipated during...
Omar Farhan Aljanaideh Concordia University, 2013 Smart material actuators are increasingly being explored for various micropositioning applications. Magnetostrictive actuators, in particular, are considered attractive for micro/nano positioning and high speed precision machining due to their high energy density, resolution and force capacity. The magnetostrictive actuators, similar to other sm...
When an elastomer approaches or retracts from adhesive indenter, the elastomer’s surface can suddenly become unstable and reshape itself quasi-discontinuously, e.g., when small-scale asperities jump into snap out of contact. Such dynamics lead to a hysteresis between approach retraction. In this study, we quantify numerically analytically ensuing unavoidable energy loss for rigid indenters with...
