2001 Image of the active delta front before Hurricanes Katrina and Rita destroyed much of the delta in 2005. The Mississippi River Delta is the confluence of the Mississippi River with the Gulf of Mexico in Louisiana, southeastern United States. The river delta is a three-million-acre (4,700 sq mi; 12,000 km 2) area of land that stretches from ...
data. Delta Librae, Latinized from δ Librae, is a variable star in the constellation Libra. It has the traditional name Zuben Elakribi, a variant of the traditional name of Gamma Librae. [11] With μ Virginis it forms one of the Akkadian lunar mansions Mulu-izi [12] (meaning "Man-of-fire" [13] ). δ Librae is approximately 300 light years from ...
Colt Delta Elite. The Colt Delta Elite is a modified series 80 M1911 pistol chambered for the 10mm Auto cartridge. It was first introduced in 1987 by the Colt's Manufacturing Company. [1] The Delta Elite is credited as being the first firearm produced by a major manufacturer to chamber the 10mm.
Neretva Delta is the river delta of the Neretva, a river that flows through Bosnia and Herzegovina and Croatia and empties in the Adriatic Sea. The delta is a unique landscape in southern Croatia, [2] and a wetland that is listed under the Ramsar Convention as internationally important, as the wetland extends into the Hutovo Blato in Herzegovina.
The Delta rocket family was a versatile range of American rocket -powered expendable launch systems that provided space launch capability in the United States from 1960 to 2024. Japan also launched license-built derivatives ( N-I, N-II, and H-I) from 1975 to 1992. More than 300 Delta rockets were launched with a 95% success rate.
Single delta potential. The time-independent Schrödinger equation for the wave function ψ(x) of a particle in one dimension in a potential V(x) is. where ħ is the reduced Planck constant, and E is the energy of the particle. The delta potential is the potential. where δ(x) is the Dirac delta function. It is called a delta potential well if ...
t. e. 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. [2] [3] [4] Since there is no function having this property, modelling the ...
Kronecker delta. In mathematics, the Kronecker delta (named after Leopold Kronecker) is a function of two variables, usually just non-negative integers. The function is 1 if the variables are equal, and 0 otherwise: or with use of Iverson brackets : For example, because , whereas because . The Kronecker delta appears naturally in many areas of ...
