At the same time, one should not overlook the strong electrothermal effect on the metal and composite elements of the test object of the long-term C-current component of artificial lightning, according to [7, 8], which carries through its round support zone at the object of relatively small outer diameter (up to 6 mm [10]) the huge values of the electric charge [q.sub.0] (up to [+ or -] 200 C).
One useful feature for routine thermal inspection of equipment is the ability to scan a QR code that is attached to a machine or test object for automatically tagging and saving thermal images without any error-prone manual entries.
For instance, a patent-pending normalisation technique uses a unique algorithm to test object recognition more quickly.
"Mercury is the perfect test object for these experiments because it is so sensitive to the gravitational effect and activity of the sun," Antonio Genova from MIT, lead author of the study who is working at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in (https://www.nasa.gov/feature/goddard/2018/nasa-team-studies-middle-aged-sun-by-tracking-motion-of-mercury) a statement Thursday.
For each test object, we designated one course on the ascending ramp and one course on the descending ramp as a complete round.
This involves many steps, which differ in test object (system under test), test objective, test phase, test environment.sup.1, and the related work packages.
This article discusses the effect of a test object (an exemplar) on the measured performance of a metal detector.
Terrestrial laser scanner measures the distance, horizontal and vertical angle between the device and the test object (Fig.
First, rats might learn to respond not only to the third test object, but also the second and fourth, because the second and fourth objects were also reinforced on test trials.
A leak detector is a test instrument designed to locate and measure the amount of leakage from a sealed test object or vacuum system during helium leak testing operations.
The innovative system will save money when the accelerometer has to be fixed permanently on to the test object; only the mount itself-costing from just $38 - has to be affixed, whilst the more expensive accelerometer can be removed at the end of the test or swapped with an accelerometer of different sensitivity.
