Wavelet analysis of bender element signals [PDF]
Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near-field effects and reflected waves. These may mask the first arrival of the shear wave, making its detection difficult in the time domain. This paper describes an approach for measuring the shear wave arrival time through analysis of

The maximum shear modulus of expansive soil during wetting-drying processes and its prediction
In order to examine the dynamic characteristics of expansive soil in natural environment, the maximum shear modulus of undisturbed and remoulded Nanyang expansive soil specimens were tested by using a triaxial apparatus equipping with a pair of bender ...

Design of an Acoustic Bender Transducer for Active Sonobuoys
Recent underwater vehicles can operate with a much lower level of noise, which increases the need for an active sonobuoy with a high detection performance. These active sonobuoys mainly use bender transducers as a projector that emits sound waves.

Static and dynamic characterisation of Agartala peat [PDF]
Peat is a unique soil type whose properties vary widely compared to other soils due to its high water content, low shear strength and high compressibility. Thus, construction on peat deposits is challenging and needs proper attention from engineers.

New Clues on the Calcium Underabundance in Early-Type Galaxies [PDF]
We use our new stellar population models, which include effects from variable element abundance ratios, to model the Ca4227 absorption line indices of early-type galaxies (Trager et al.), and to derive calcium element abundances.
