  2. Anomaly - Wikipedia

    en.wikipedia.org/wiki/Anomaly

    In astronomy, an anomaly of an elliptical orbit, generally measured with respect to an apsis, usually the periapsis Anomalous precession , another term for "apsidal precession" Eccentric anomaly , an intermediate value used to compute the position of a celestial object as a function of time

  3. Anomaly detection - Wikipedia

    en.wikipedia.org/wiki/Anomaly_detection

    In data analysis, anomaly detection (also referred to as outlier detection and sometimes as novelty detection) is generally understood to be the identification of rare items, events or observations which deviate significantly from the majority of the data and do not conform to a well defined notion of normal behavior. [1]

  4. Opposite - Wikipedia

    en.wikipedia.org/wiki/Opposite

    An antonym is one of a pair of words with opposite meanings. Each word in the pair is the antithesis of the other. A word may have more than one antonym. There are three categories of antonyms identified by the nature of the relationship between the opposed meanings.

  5. Mean anomaly - Wikipedia

    en.wikipedia.org/wiki/Mean_anomaly

    where M 0 is the mean anomaly at the epoch t 0, which may or may not coincide with τ, the time of pericenter passage. The classical method of finding the position of an object in an elliptical orbit from a set of orbital elements is to calculate the mean anomaly by this equation, and then to solve Kepler's equation for the eccentric anomaly.

  6. Contronym - Wikipedia

    en.wikipedia.org/wiki/Contronym

    Hindi: कल and Urdu: کل (kal) may mean either "yesterday" or "tomorrow" (disambiguated by the verb in the sentence).; Icelandic: fram eftir can mean "toward the sea" or "away from the sea" depending on dialect.

  7. True anomaly - Wikipedia

    en.wikipedia.org/wiki/True_anomaly

    In celestial mechanics, true anomaly is an angular parameter that defines the position of a body moving along a Keplerian orbit.It is the angle between the direction of periapsis and the current position of the body, as seen from the main focus of the ellipse (the point around which the object orbits).

  8. Anomalistics - Wikipedia

    en.wikipedia.org/wiki/Anomalistics

    Anomalistics is the use of scientific methods to evaluate anomalies (phenomena that fall outside current understanding), with the aim of finding a rational explanation. [1] ...

  9. Unpaired word - Wikipedia

    en.wikipedia.org/wiki/Unpaired_word

    An unpaired word is one that, according to the usual rules of the language, would appear to have a related word but does not. [1] Such words usually have a prefix or suffix that would imply that there is an antonym, with the prefix or suffix being absent or opposite.
