In statistics, the delta method is a method of deriving the asymptotic distribution of a random variable. It is applicable when the random variable being considered can be defined as a differentiable function of a random variable which is asymptotically Gaussian .
The FAA had read Delta 1989 to be in Cleveland airspace and ordered Cleveland Center to watch for Delta 1989 as a suspected hijacking. A Cleveland controller thought he heard "Get out of here" and "We have a bomb on board" coming from Delta 1989. The Delta pilot denied any cockpit intrusion and stated that everyone on board was fine.
Delta Circini (δ Cir), is a multiple star system located in the constellation Circinus. Delta Circini is also known as HR 5664 , and HD 135240 . The system has a combined apparent visual magnitude of +5.09, and is located at a distance of about 700 pc (2,300ly) from the Sun.
Delta is a situational awareness [1] and battlefield management system developed and used in Ukraine. The system integrates information from a broad network of participants, including troops, civilian officials, and vetted bystanders; [2] and a wide range of streams, [1] including sensors, intelligence sources, surveillance satellites and drones, [2] especially geolocated data, which it maps ...
November 10, 1946: Delta Air Lines Flight 10, a Douglas DC-3 which departed Jackson, Mississippi attempting to land at then Meridian Key Field (MEI) in a thunderstorm and winds, had a runway excursion after landing, going beyond the end of the runway and up the western slope of a ditch adjoining the highway adjacent to the airport, bouncing over a highway, and coming to rest with the nose ...
Latin delta (ẟ, lower-case only) is a Latin letter similar in appearance to the Greek lowercase letter delta (δ), but derived from the handwritten Latin lowercase d.It is also known as "script d" or "insular d" and is used in medieval Welsh transcriptions for the [] sound (English th in this) represented by "dd" in Modern Welsh.
In mathematical analysis, the Dirac delta function (or δ distribution), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one.
Delta Crucis is a strong candidate Beta Cephei variable. [5] Its rotation is very fast, with a projected rotational velocity of 210 km s −1. [11] Delta Crucis is a member of the Lower Centaurus Crux (LCC) component of the Scorpius–Centaurus association, which is an OB association of massive stars that share a common origin and motion ...
