The Kardashian Index (K-Index), named after Kim Kardashian, is a satirical measure of the discrepancy between a scientist's social media profile and publication record. Proposed by Neil Hall in 2014, the measure compares the number of followers a research scientist has on Twitter to the number of citations they have for their peer-reviewed work.

Nov 22, 2022 · The K-index quantifies disturbances in the horizontal component of earth's magnetic field with an integer in the range 0-9 with 1 being calm and 5 or more indicating a geomagnetic storm. It is derived from the maximum fluctuations of horizontal components observed on a magnetometer during a three-hour interval. The planetary 3-hour-range index ...

K index. ( Also called George's index.) A stability index that is a measure of thunderstorm potential based on temperature lapse rate, moisture content of the lower troposphere, and the vertical extent of the moist layer. The K index is determined by the following equation: where T is the temperature and T'd is the dewpoint in degrees Celsius ...

K指数(けーしすう, 英: K-Index)は、気象学において、雷 雨の発生確率を評価するために用いられ、特に熱雷の発生確率と相関性が高い指数である。 KINXとも記す。. 1960年にJ.J.Georgeが発表した評価方式。 は気温[℃]、 は露点温度[℃]として、各高度における値をもってK指数を以下の通り算出する。

Apr 21, 2020 · It ranges from 0 (quiet) to 400 (severe storm). A = 0 – 7 Quiet. A = 8 – 15 Unsettled. A= 8 – 15 Unsettled. A = 16 – 29 Active. A = 30 – 49 Minor storm. A = 50 – 99 Major storm. A = 100 – 400 Severe storm. Generally, propagation conditions are best when the A index is 15 or lower, and the K index is 3 or lower.

Apr 25, 2012 · K-index: This index is due to George (1960) and is defined by . The first term is a lapse rate term, while the second and third are related to the moisture between 850 and 700 mb, and are strongly influenced by the 700-mb temperature–dewpoint spread. As this index increases from a value of 20 or so, the likelihood of showers and thunderstorms ...

The K-Index or George's Index is a measure of thunderstorm potential in meteorology. According to the National Weather Service, the index harnesses measurements such as "vertical temperature lapse rate, moisture content of the lower atmosphere, and the vertical extent of the moist layer." [1] It was developed by the American meteorologist ...

The K index is a “quasi logarithmic” number and as such cannot be averaged to give a longer-term view of the state of the Earth’s magnetic field. Thus was born the A index, a daily average. At each 3- hour increment the K index at an obser-vatory is converted to an equivalent “a” index using Table 1, and the 8 a-index

Jul 30, 2014 · Where F (a) is the actual number of twitter followers of researcher X and F (c) is the number researcher X should have given their citations. Hence a high K-index is a warning to the community that researcher X may have built their public profile on shaky foundations, while a very low K-index suggests that a scientist is being undervalued.

Kamijou Touma (上条 当麻, Kamijō Tōma?) is the main protagonist of the Toaru Majutsu no Index series and an important character in the Toaru Kagaku no Railgun series. As a Level 0 Academy City first-year high school student, his point-of-view allows the audience to become acquainted to the mysterious world of Toaru Majutsu no Index, and is mostly involved in the …

The planetary 3-hour-range index Kp is the mean standardized K-index from 13 geomagnetic observatories between 44 degrees and 60 degrees northern or southern geomagnetic latitude. The scale is O to 9 expressed in thirds of a unit, e.g. 5- is 4 2/3, 5 is 5 and 5+ is 5 1/3. This planetary index is designed to measure solar particle radiation by ...

CalinskiHarabaszEvaluation is an object consisting of sample data (X), clustering data (OptimalY), and Calinski-Harabasz criterion values (CriterionValues) used to evaluate the optimal number of clusters (OptimalK).The Calinski-Harabasz criterion is sometimes called the variance ratio criterion (VRC). Well-defined clusters have a large between-cluster variance and a small within …
