dynamic braking
Science; General science
A technique for braking in which mechanical energy is converted to heat or electrical energy in order to slow or stop motion. An all-mechanical dynamic brake consists of rotating ...
ellipsometry
Science; General science
A technique for determining the properties of a material from the characteristics of light reflected from its surface. The materials studied include thin films, semiconductors, ...
Monte Carlo method
Science; General science
A technique for estimating the solution, x , of a numerical mathematical problem by means of an artificial sampling experiment. The estimate is usually given as the average ...
photoacoustic spectroscopy
Science; General science
A technique for measuring small absorption coefficients in gaseous and condensed media, involving the sensing of optical absorption by detection of sound. It is frequently called ...
helioseismology
Science; General science
A technique for probing the interior of the Sun, using methods akin to terrestrial seismology. The Sun, although the nearest star by far, is a typical star, so what can be learned ...
matrix isolation
Science; General science
A technique for providing a means of maintaining molecules in an inert medium at low temperature for spectroscopic study. This method is particularly well suited for preserving ...
snow surveying
Science; General science
A technique for providing an inventory of the total amount of snow covering a drainage basin or a given region. Most of the usable water in western North America originates as ...
