Two primary stress tests utilized are a treadmill test using ECG/electrophysiology metrics and nuclear testing, each have unique sensitivity and specificity values. The treadmill test, employing the modified Bruce protocol , [ 20 ] demonstrates a sensitivity range of around 73-90% and a specificity range of around 50-74%.
The goal and objectives, the time frame, the stress test level and the total costs of the stress test are defined. Phase 2: Assessment, during which the stress test at the component and the system scope is performed, including fragility [12] and risk [13] analysis of the CIs for the stressors defined in Phase 1. The stress test can result in ...
Rope trick effects visible from one of Operation Tumbler–Snapper's tower-mounted test shots in 1952, taken with a rapatronic camera. The adjacent photograph shows two unusual phenomena: bright spikes projecting from the bottom of the fireball, and the peculiar mottling of the expanding fireball surface.

In order to obtain spatial information about the gamma-ray emissions from an imaging subject (e.g. a person's heart muscle cells which have absorbed an intravenous injected radioactive, usually thallium-201 or technetium-99m, medicinal imaging agent) a method of correlating the detected photons with their point of origin is required.
The reference to a person dropping dead after good performance on stress treadmill (Further Research: "However, there was also long-standing experience that some people could exercise all the way to maximum predicted heart rate, have no abnormal symptoms and completely normal stress test results, only to die of a massive heart attack within a ...

Greenwater, a Lawrence Livermore test, was to be fired in Area 19, [10] and was a test of an x-ray laser system. [12] The test was cancelled 16 July 1992. [13] The Greenwater nuclear device had already been assembled at the time of cancellation, and had to be dismantled. [14] A fourth test, Mighty Uncle, was planned for 1993.
