New Approach to Resonant Column Testing

Geotechnical Testing Journal, 2013
Abstract This paper describes a new type of torsional resonant column device that has a quasi-fixed base and free top. In this device, a relatively rigid torque transducer is placed between the bottom platen and the fixed chamber base. A large capacity torque motor excites the top platen.

Redesigned Air-Column Resonance Apparatus

The Physics Teacher, 2003
This paper describes a redesigned air-column resonance apparatus1 that offers several advantages over the traditional one.2 It does away with water or the long rod to vary the length of the air column. Instead a specially designed piston is moved inside a plastic or glass tube by external magnets to vary the length of the air column.

The Ultrasonic Interferometer with Resonant Liquid Column

Proceedings of the IRE, 1948
The ultrasonic interferometer is simple in construction and operation, and yields accurate and consistent data. From these data, one can readily determine the velocity of sound in a liquid with high accuracy. Formerly, the absorption of sound in the liquid and the coefficient of reflection at the reflector surface has been obtained through a ...

Evaluation of Resonant Column Test Devices

Journal of the Geotechnical Engineering Division, 1976
Resonant column tests were performed by six participants in a program designed to evaluate results from various devices. The participants were Drnevich, Hardin, Woods, Shannon & Wilson, Inc., the U.S. Army Engineer Cold Regions Research and Engineering Laboratory, and the U.S. Army Engineer Waterways Experiment Station.

The Damping of Dipole Resonances of a Plasma Column†

Journal of Electronics and Control, 1964
Abstract Experiments are reported in which the subsidiary resonances of a plasma column arising from electron standing waves in the column are examined in comparison with the principal resonance (when the column behaves essentially as a dielectric medium).

Resonances and anti-resonances of a plasma column in a helicon plasma source

Physics Letters A, 1995
Abstract We consider excitation of a plasma cavity in a range of parameters typical for helicon sources. The resonance and anti-resonance properties are shown to be intrinsic for a plasma column in this case, as well as for any bounded plasma system. If a column is well separated from a conductive wall, even small collisions result in the destruction

Experimental Investigation on the Resonance of a Liquid Column in a Capillary Tube

Journal of Colloid and Interface Science, 1999
Using a visualization technique, we observed the resonance of a water column trapped in a vertically oriented capillary tube due to acoustic excitation. The analysis of the quasi-static response suggests that the upper nonvisible meniscus followed the imposed flow by means of a sliding contact line without changing its shape.

Magnetic Resonance Imaging in the Spinal Column and Craniovertebral Junction

Radiologic Clinics of North America, 1984
The sensitivity of magnetic resonance imaging (MRI) to tissue alterations is particularly useful in spinal cord imaging. In addition to excellent anatomic display of this compact and complex area, syrinx cavities, tumors, and degenerating disks can be identified before they cause the anatomic distortion often necessary for detection by conventional ...
