It is also possible to test objects
by indirectly action the indicated discharge channel to the elements of the object located near the lightning passage.
The process defines four basic verification methods for evidencing that the function or item under test, i.e., the test object
, meets its functional requirements :
where [u.sub.prpy] is the measurement uncertainty associated with material properties of the test object
, where the two material properties that are of concern are the electrical conductivity, [sigma], and the magnetic permeability, [mu]; [u.sub.geom] is the uncertainty for the physical dimensions of the test object
; and [U.sub.orient] is the uncertainty associated with the orientation of the test object
relative to the metal detector under test.
That task involves calibration of camera-lens set, the preparation of the test object
, tachymetric measurement and finally laser scanning measurement and hemispherical photography.
The procedure for Transfer tests 2-4 was identical to that of Transfer test 1, except for training and test objects
There is a process to reduce the internal pressure of the test object
to a level where testing can begin (this process is called "roughing").
A simplied 3-D test object
has been designed to represent the human body in experiments that took place inside the HV laboratory.
Toxicity index was -119%, which indicates a significant stimulation of swimming activity of the test object
with the addition of esfenvalerate at low exposure time (30 min.).
The "synchronic approach" is "almost synonymous" with the structural approach; however, it is used to emphasize the evolutionary aspects in the test object
. The substratum for this object is a "phenomena level" or a "range of phenomena" associated with this object.
Our test object
was the ISO 12233 compliant A4sized Danes Picta DCR3 table.
In this paper, the algorithm for the calculation of the time delays of the linear phased array probe is presented, when the beam has to be focused at the specified depth in the test object
, inspected using the immersion testing.
Then, a novel, test object
was presented, where this object was "derived" from the reference in several ways: (1) similar weight as the reference, (2) a composite comprising a stack of the reference objects (e.g., two reference objects packed together), and (3) scaled version of the reference (i.e., scaled up or down in volume with respect to the reference).
