Generalised Impedance P. ZOLTOWSKI and B. LEGAWIEC, J. Electroanal. Chem., 2004, 572, (2), 205210 Transport of H in elastic metals has been analysed in terms of an impedance-like non-linear transfer function (TF). The equilibrium in a membrane was perturbed by application of a sinusoidal signal of concentrations of H, of large amplitude, to a surface. The fundamental harmonics of periodically ...
A big challenge in studying organic rich shale is to predict its kerogen content and maturity from indirect observations. Kerogen maturation changes shale texture; for example, it generates microcracks and fractures in the matrix. Assessment of maturity from indirect measurements can be greatly enhanced by exploiting any existing correlations between physical properties, microstructure, and ker...
Aortic input impedance relates pressure to flow at the aortic entrance distal to the aortic valve. We designed the CircAdapt three-element model of this impedance, consisting of resistive wave impedance, arterial compliance and peripheral resistance. Direct association of the elements with physical properties facilitated incorporation of nonlinear elastic properties of wall material and adaptat...
Series Elastic Actuators provide many benefits in force control of robots in unconstrained environments. These benefits include high force fidelity, extremely low impedance, low friction, and good force control bandwidth. Series Elastic Actuators employ a novel mechanical design architecture which goes against the common machine design principal of “stiffer is better”. A compliant element is pl...

This paper presents a new algorithm for conductivity imaging. Our idea is to extract more information about the conductivity distribution from data that have been enriched by coupling impedance electrical measurements to localized elastic perturbations. Using asymtotics of the elds in the presence of small volume inclusions, we relate the pointwise values of the energy density to the measured d...
