Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

A glance at velocity structure of Izmir

AIP Conference Proceedings, 2016
In this study; we investigated velocity structure of Izmir and surroundings. We used local earthquake data which was recorded by different type of instruments and obtained high resolution 3D sections. We selected more than 400 earthquakes which were occurred between 2010 and 2013.

Velocity Structure of a Gas Hydrate Reflector

Science, 1993
Seismic reflection profiles across many continental margins have imaged bottom-simulating reflectors (BSRs) parallel to the seabed; these are often interpreted as the base of a zone in which methane hydrate "ice" is stable. Waveform inversion of seismic reflection data can be used to estimate from seismic data worldwide the velocity structure of a BSR ...

A STRUCTURAL STUDY OF THE INCOME VELOCITY OF CIRCULATION

The Journal of Finance, 1974
ONE OF THE GENERALLY ACCEPTED facts of monetary theory is that the income velocity of circulation of the money supply1 is not a constant. However, many analysts feel that movements in this measure exhibit some regularity. For example, the view is often expressed that changes in velocity tend to follow changes in the rate of growth of the money supply ...

Measurements of the Velocity and Turbulence Structure

AIAA Journal, 1997
The turbulent ow structure of a tip vortex generated by a hovering rotor was investigated with the use of three-dimensional laser Doppler velocimetry. The velocity ® eld was measured at ® ve wake ages, with the three components of turbulence being measured at the three earliest ages.
