Introduction Les cancers cutanes sont les premiers dont l’origine professionnelle a ete decrite. Malgre l’existence de tableaux de maladies professionnelles (MP) liees a l’arsenic, aux huiles derivees du petrole et aux derives de la houille, po

A new equivalent circuit is proposed for a contour-vibration-mode piezoelectric transformer (PT). It is shown that the usual lumped equivalent circuit derived from the conventional Mason approach is not accurate. The proposed circuit, built on experi

A bilaminar consisting of a piezoelectric ceramic disk mounted on a polymer disk was chosen to build an ultrasonic proximity detector in air. The influences of the polymer and the ceramic thicknesses on the transducer's dynamic behaviour are investig

This paper is devoted to the two-dimensional modelling of shear vibration modes of a piezoceramic plate for assessing the influence of geometry on the parameter measurement. The two-dimensional model is based on the assumption that a plane wave propa

This paper deals with the vibration mode determination of a rectangular plate loaded on each face. The resonant frequencies, the mechanical displacement and the electrical impedance of the plate are calculated using a three-dimensional approach based
