Time Domain Waveforms of a Line-Focus Transducer Probing Anisotropic Solids

January 1, 1997
Author(s)
Nelson N. Hsu, Gerald V. Blessing, D Xiang
We have developed a large lensless line-focus wideband ultrasonic transducer which can be used to probe solid materials through water. With conventional ultrasonic equipment the transducer can perform time and polarization resolved surface and body wave

Predicting broadband resonator-waveguide coupling for microresonator frequency combs through fully connected and recurrent neural networks with and without attention mechanism

May 24, 2023
Author(s)
Ergun Simsek, Masoud Soroush, Gregory Moille, Kartik Srinivasan, Curtis Menyuk
Broadband microresonator frequency combs are being intensely pursued for deployable technologies like optical atomic clocks. Spectral features, such as the dispersion in their coupling to an access waveguide, are critical for engineering these devices for

New Connections for Enhancing Robustness of Precast Concrete Frame Structures

February 24, 2018
Author(s)
Travis E. Thonstad, Yihai Bao, Jonathan M. Weigand, Joseph A. Main, Hai S. Lew
A recent experimental and computational study of two precast concrete moment-frame assemblies under a column removal scenario revealed vulnerabilities in the moment connections arising from (a) local bending of reinforcing bars due eccentricity in the

Preface to Dislocatrions 2000 Proceedings

October 16, 2008
Author(s)
Lyle E. Levine, L -. Kubin, R -. Becker
During the 1950's and 1960's, a widespread international effort was underway to lay the foundations for a fundamental, dislocations-based understanding of plastic deformation and strain hardening. This effort lagged, however, as the existing theoretical
