Measurement of wakefield intensity

Journal of Physics B: Atomic, Molecular and Optical Physics, 2009
We report on the measurement of the wakefield of an ion moving through a beam–foil plasma using an indirect experimental method. The standard beam–foil time-of-flight technique is used to measure the lifetime of the perturbed H-like V 2s2S1/2 state due to its passage through the wakefield.

A MEASURE OF CROPPING INTENSITY∗

The Professional Geographer, 1978
The measurement of agricultural intensity is fundamental to an understanding of spatial organization of agriculture. This paper develops a new index of cropping intensity from land use data. The length of time for which a crop stays in the field, a factor ignored in other indirect measures of cropping intensity, has been incorporated in the new index ...

Solar intensity measurements

2014 International Conference on Green Computing Communication and Electrical Engineering (ICGCCEE), 2014
People in underprivileged countries could benefit from the use of a solar distributed generation system. The tracking module is designed with the help of the stepper motor which does not require sensors for tracking. This can be done by knowing the step angle.

Measuring Sound Intensity

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">We are basically interested in Sound Intensity whenever we deal with sources of sound in noise control. The development of techniques and new tools for the direct measurement of the flow of acoustic energy offer new ways for determination of source location, source ranking, energy flow path and absorption ...

Measurement of sensory intensity

Behavioral and Brain Sciences, 1981
AbstractThe measurement of sensory intensity has had a long history, attracting the attention of investigators from many disciplines including physiology, psychology, physics, mathematics, philosophy, and even chemistry. While there has been a continuing doubt by some that sensation has the properties necessary for measurement, experiments designed to ...

Measurement of sound intensity

Journal of Sound and Vibration, 1977
A method is formulated for sound intensity measurement in a non-dispersive medium. It is shown that two microhpones are necessary for obtaining the components of the intensity vector at a given point. In addition, errors associated with measurements are discussed.
