In 1988, IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control (TUFFC) hosted a Special Issue Ultrasound Exposimetry (vol. 35, no. 2). This issue is now recognized as seminal; it laid the groundwork for development of numerous domestic international standards that are still widely used calibration regulatory characterization ultrasound devices. Since then, medical has undergon...

Insight into a material’s high temperature mechanical and microstructural properties can be gained from knowledge of its elastic moduli. For a single-crystal material, the elastic modulus, Cijkl, provides information on the strain (εkl) stress (σij) relationship given by σij = Cijkl•εkl. This relationship shows that, for a given strain, a large elastic modulus will induce a large stress in the ...

The paper summarizes the creation of a robust online grain size gauge for hot strip mill. A method and algorithm calculating from measured ultrasonic attenuation is presented. This new self-calibrating, does not rely on geometrical reference sample can cope with effects diffraction attenuation. model based 52 quenched samples more than 23,000 laser ultrasonics shots has correlation coefficient ...

Recognition of aberrant root canal configurations is critical to successfully negotiate and treat a one such aberrancies C shape system. The fins webs present in system presents challenge debridement obturation. Knowledge variations through advanced imaging modalities like CBCT, rotary hand instruments assisted with ultrasonics modified obturation techniques aid effective management shaped cana...
