In quality management, a nonconformity (sometimes referred to as a non conformance or nonconformance or defect) is a deviation from a specification, a standard, or an expectation. Nonconformities or nonconformance can be classified in seriousness multiple ways, though a typical classification scheme may have three to four levels, including ...
Preventive action is any proactive method used to determine potential discrepancies before they occur and to ensure that they do not happen (thereby including, for example, preventive maintenance, management review or other common forms of risk avoidance). Corrective and preventive actions include stages for investigation, action, review, and ...
In mathematics, discrepancy theory describes the deviation of a situation from the state one would like it to be in. It is also called the theory of irregularities of distribution . This refers to the theme of classical discrepancy theory, namely distributing points in some space such that they are evenly distributed with respect to some ...
Geometric discrepancy theory [1] is a sub-field of discrepancy theory, that deals with balancing geometric sets, such as intervals or rectangles.The general research question in this field is: given a set of points in a geometric space, and a set of objects in the same space, can we color each point in one of two different colors (e.g. black and white), such that each object contains roughly ...
For example, if n=4 and one of the permutations is (1,2,3,4), then its interval set of contains e.g. the edges (1,2), (1,2,3), (2,3), (2,3,4), etc. The discrepancy of the permutations p 1 , ..., p m is the minimum, over all black-white colorings of the integers in [ n ], of the maximum over all intervals, of the difference between the number of ...

In mathematics, a low-discrepancy sequence is a sequence with the property that for all values of , its subsequence , …, has a low discrepancy.. Roughly speaking, the discrepancy of a sequence is low if the proportion of points in the sequence falling into an arbitrary set B is close to proportional to the measure of B, as would happen on average (but not for particular samples) in the case ...
Best rational approximants for π (green circle), e (blue diamond), ϕ (pink oblong), (√3)/2 (grey hexagon), 1/√2 (red octagon) and 1/√3 (orange triangle) calculated from their continued fraction expansions, plotted as slopes y/x with errors from their true values (black dashes)
