TL;DR: A theory of a piezoelectric axisymmetric bimorph is presented in this paper, where the bending moments and stretching forces produced by voltage are derived, and the results obtained by means of the described theory and numerical methods have been verified experimentally or by comparing them with results obtained analytically for a simple structure.

TL;DR: An approach to breast diagnostics which employs ultrasound transmission and reflection tomography imaging, which shows good correlation of glandular tissue areas with their visualization on MRI images and predicts that the implemented UST device offering fusion of reconstructed images may contribute to achieving a new standard for breast cancer diagnostics through non-invasive, fast and cheap screening tests.

TL;DR: In this article, a system was designed to measure personalized head-related impulse responses (HRIRs) efficiently for over one thousand locations around a listener in a relatively short time (about 10 min).

TL;DR: The obtained results indicate that the developed UTT and URT methods, after the acceleration of the scanning process, thus enabling in vivo examination, may be successfully used for detection and detailed characterization of breast lesions in women.

TL;DR: In this paper, the authors present a sound-absorbing and insulating enclosures for low ultrasonic frequencies (20-30 kHz) where the boards made of ceramic fibers have been chosen as the optimal sound absorbing material.
