The term "persistent" was first introduced by Atkinson and Morrison [1] in the sense of orthogonal persistence: they used an adjective rather than a verb to emphasize persistence as a property of the data, as distinct from an imperative action performed by a program. The use of the transitive verb "persist" (describing an action performed by a ...
Persistence (discontinuity), a concept in geotechnical engineering; Persistence (linguistics), a principle of grammaticalization; Persistence (psychology), a personality trait; Persistence of vision, a theory on how the illusion of motion in films is achieved; Persistence forecasting, predicting the future to be the same as the present
Perhaps the simplest persistent data structure is the singly linked list or cons-based list, a simple list of objects formed by each carrying a reference to the next in the list. This is persistent because the tail of the list can be taken, meaning the last k items for some k, and new nodes can be added in front of it. The tail will not be ...
Persistent may refer to: Persistent data; Persistent data structure; Persistent identifier; Persistent memory; Persistent organic pollutant; Persistent Systems, a ...
Psychologist K. Anders Ericsson, in his book Peak: Secrets from the New Science of Expertise, criticized the tendency to credit persistent practice to traits such as grit or willpower. He wrote: "It may seem natural to assume that these people who maintain intense practice schedules for years have some rare gift of willpower or 'grit' or 'stick ...
Persistence of vision is the optical illusion that occurs when the visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. [1] The illusion has also been described as "retinal persistence", [2] "persistence of impressions", [3] simply "persistence" and other variations ...
Critics of persistence studies argue the pitfalls of the approach lie in a failure to recognize institutional change ("anti-persistence"), vague mechanisms, the insufficient use (or misuse) of historical sources and narratives, the compression of history, and a failure to account for the effects of geography."
The additive persistence of 2718 is 2: first we find that 2 + 7 + 1 + 8 = 18, and then that 1 + 8 = 9. The multiplicative persistence of 39 is 3, because it takes three steps to reduce 39 to a single digit: 39 → 27 → 14 → 4. Also, 39 is the smallest number of multiplicative persistence 3.
