Dazzle camouflage, also known as razzle dazzle (in the U.S.) or dazzle painting, is a family of ship camouflage that was used extensively in World War I, and to a lesser extent in World War II and afterwards. Credited to the British marine artist Norman Wilkinson, though with a rejected prior claim by the zoologist John Graham Kerr, it ...
Dazzle consists in painting obtrusive patterns on vertical surfaces. Unlike some other forms of camouflage, dazzle works not by offering concealment but by making it difficult to estimate a target's range, speed and heading. Each ship's dazzle pattern was unique to make it more difficult for the enemy to recognize different classes of ships.
A drug test (also often toxicology screen or tox screen) is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva —to determine the presence or absence of specified parent drugs or their metabolites. Major applications of drug testing include detection of the presence of performance ...
Testing kit or test kit is a discerning device used in a wide range of areas including: Medical diagnosis. Reagent testing. Rape kit. Pregnancy test. Gunshot residue. Soil test. Category:
A test is done by taking a small scraping from a pill and placing it in the reagent testing liquid or dropping the reagent onto the scraping. The liquid will change colour when reacting with different chemicals to indicate the presence of certain substances. Testing with a reagent kit does not indicate the pill is safe.
A lateral flow test ( LFT ), [1] is an assay also known as a lateral flow device ( LFD ), lateral flow immunochromatographic assay, or rapid test. It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment. LFTs are widely used in medical diagnostics in ...
Smoke tests are a subset of test cases that cover the most important functionality of a component or system, used to aid assessment of whether main functions of the software appear to work correctly. [1] [2] When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called a ...
Design for testing. Design for testing or design for testability ( DFT) consists of IC design techniques that add testability features to a hardware product design. The added features make it easier to develop and apply manufacturing tests to the designed hardware. The purpose of manufacturing tests is to validate that the product hardware ...
