Comparison between piezoelectric material properties obtained by using low-voltage magnitude frequency sweeping and high-level short impulse signals.
Determination of electromechanical piezoceramic material parameters is usually done by fitting the measured input electrical impedance of the piezoceramic sample to the theoretical modelling equationExpand
Electromechanical characterization of piezoceramic elements around resonance frequencies at high excitation levels and different thermodynamic conditions
Electromechanical characterization of piezoceramic bulk elements around resonance is usually done with low-level continuous excitation signals at room temperature, but in real applications suchExpand
Angle-differential cross sections and spin-asymmetry parameters for spin-polarized electron-impact excitation of spin-polarized cesium atoms
Relative angle-differential cross sections and spin-asymmetry parameters are presented for spin-polarized electron-impact excitation of spin-polarized cesium atoms for incident projectile energiesExpand
Detailed experimental and theoretical study of elastic scattering at intermediate energies in the electron-cesium system
A series of measurements and calculations has been carried out for angle-differential elastic e-Cs scattering in the intermediate-energy region from 4 eV to 25 eV. The experiment used spin-polarizedExpand
INFLUENCE OF PIEZOELECTRIC ANISOTROPY ON ELECTROMECHANICAL PERFORMANCE OF ULTRASOUND NDT PROBES AT ELEVATED TEMPERATURES
When designing an ultrasound non-destructive (NDT) probe for high temperature applications, one has to take into account a multitude of temperature induced effects, such as the temperature dependenceExpand
Multielement ultrasound and eddy current integrated probe for non-destructive evaluation of nuclear reactor pressure vessel head penetrations
An integrated combined UT (ultrasound testing) and ECT (eddy current testing) mult ielement probe prototype for inspection of gaps in nuclear reactor pressure vessel head penetra tions (RVHPs) wasExpand
Spin Asymmetry Measurements in Inelastic e ‐ Cs Collisions
We report on measurements of angle‐differential electron impact 6S → 6P and 6S → 5D excitation of the Cs atom in the intermediate‐energy region from 4 eV to 25 eV. With our spin‐polarized beams weExpand
