The Yangtze Delta or Yangtze River Delta ( YRD, Chinese: 长江三角洲 or simply Chinese: 长三角 ), previously known as the Shanghai Economic Zone, is a triangle-shaped megalopolis generally comprising the Wu -speaking areas of Shanghai, southern Jiangsu, northern Zhejiang, southern Anhui. The area lies in the heart of the Jiangnan region ...
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 ...
Emmonak is located in the large delta of the Yukon River at (62.777328, -164.544920 [3] According to the United States Census Bureau , the city has a total area of 8.6 square miles (22 km 2 ), of which, 7.5 square miles (19 km 2 ) of it is land and 1.1 square miles (2.8 km 2 ) of it (13.08%) is water.
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, to model the delta ...
Satellite image of the Amazon Delta captured by NASA in 2005. NASA satellite photograph of the Nile Delta (shown in false color) A river delta is a landform shaped like a triangle, created by the deposition of sediment that is carried by a river and enters slower-moving or stagnant water. [1] [2] This occurs at a river mouth, when it enters an ...

Delta Psi Delta, a local fraternity at California State University, Chico. Delta Psi Delta (Dartmouth), a former coed Greek organization at Dartmouth College in Hanover, New ...
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.
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.
