This paper provides a time-domain feedback analysis of the robustness performance of Gauss-Newton recursive methods that are often used in identification and control. These are recursive estimators that also involve updates of sample covariance matrices. S ...
The mechanical response of piezoelectric cantilever beams actuated by sol-gel- derived lead zirconium titanate (PZT) thin film is reported. Small multilayered beams are used to analyse the converse piezoelectric effect and to measure the mechanical deflect ...
We investigated how parameters describing the heart and the arterial system contribute to the systolic and diastolic pressures (Ps and Pd, respectively) and stroke volume (SV). We have described the heart by the varying-elastance model with six parameters ...
The direct longitudinal piezoelectric effect (d(33)) in lead zirconate titanate, barium titanate, bismuth titanate and strontium bismuth titanate ceramics was investigated with respect to the dependence on the amplitude of an alternating pressure. At low a ...
A micro system for measuring the relative displacements between a bone and an implant in a prosthetic hip of a human being has been realized. Novel are the small dimensions of the system combined with the possibility to measure relative displacements in th ...
A micro-pump for medical applications is being developed using organometallic derived PZT thin films and silicon micromachining technology. Critical issues include the deposition of 'thick' PZT films (1 to 2 mu m thickness), film processing compatibility w ...
We have studied the electrical characteristics of p‐GaAs/n‐Si (100) heterojunction diodes grown by molecular beam epitaxy in an effort to determine the interface polarity. A Ga or As pre‐exposure was used prior to the growth of p‐GaAs on n‐Si substrates to ...
Raman spectra of dihexadecylphosphatidic acid and of dimyristoylphosphatidylcholine and its longer chain homologs were obtained as a function of temp. to study the conformational order of the hydrocarbon chains in lipid bilayers. The frequency of the longi ...
New 2-dimensional NMR correlation methods are presented which allow one to obtain selected high-resoln. multiplets where all signals have pos. pure absorption peak shapes. The multiplets do not suffer from any cancellation effects, and their fine structure ...
