Ultrasonic characterization of emulsions: milk and water in oil
(1999-12-01)
Measurements of ultrasonic attenuation and velocity in milk and low concentration water-in-oil (W/O) emulsion were conducted, using a measurement cell with a double-element transducer that eliminates diffraction losses. ...
Wave Propagation In Multilayer Dielectric Periodic Structures

Thermal characterization of an ultrasonic measurement cell
(2005-12-01)
Temperature plays an important role in any sensor device, because it can affect sensor properties, limiting its accuracy and operation range. At constant temperature, ultrasonic density sensors can reach accuracies of 0.1%. ...
Energy method to calculate the density of liquids using ultrasonic reflection techniques
(2001-12-01)
In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...
A boundary element method formulation to capture strong discontinuities in solids
(2005-12-01)
A Boundary Element Method (BEM) formulation to predict the behavior of solids exhibiting displacement (strong) discontinuity is presented. In this formulation, the effects of the displacement jump of a discontinuity interface ...
