Ultrasonic transducers using radial vibrations of a piezoelectric disk
Archives of Acoustics, 2016 Suggestions concerning the use of radial vibrations of a piezoelectric disk in ultrasonic transducers working in the frequency range below 100 kHz are presented. Experimental data from investigations of two types of transducers are given, one using axial

Flutter Instability Speeds of Guided Splined Disks: An Experimental and Analytical Investigation
Shock and Vibration, 2015 “Guided splined disks” are defined as flat thin disks in which the inner radius of the disk is splined and matches a splined arbor that provides the driving torque for rotating the disk.

Lateral cephalometric analysis of asymptomatic volunteers and symptomatic patients with and without bilateral temporomandibular joint disk displacement [PDF]
, 1998 Few studies of dentofacial and orthodontic structural relationships relative to temporomandibular joint (TMJ) dysfunction have been reported. We undertook this investigation to determine any correlation of orthodontic and dentofacial characteristics with

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
