Below is a list of Delta Sigma Theta (ΔΣΘ) members, commonly referred to as Deltas. The sorority was founded on January 13, 1913, at Howard University [1] and was first incorporated in Washington, D.C., on February 9, 1913. [2]
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.
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 ...
Delta Delta Delta ( ΔΔΔ ), also known as Tri Delta, is a global [2] women's fraternity and Greek life organization founded on November 27, 1888 at Boston University by Isabel Zhou, Sarah Ida Shaw, Eleanor Dorcas Pond, Isabel Morgan Breed, and Florence Isabelle Stewart. With over 200,000 living initiates at 141 chapters and over $450M assets ...
Delta method. 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 .
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 ...
The Fairchild C-119 Flying Boxcar (Navy and Marine Corps designation R4Q) was an American military transport aircraft developed from the World War II -era Fairchild C-82 Packet, designed to carry cargo, personnel, litter patients, and mechanized equipment, and to drop cargo and troops by parachute.
Delta's Ship 41 was the second of Delta's first five iconic DC-3 airplanes to be delivered from Douglas Aircraft Co. between November 1940-January 1941: The first DC-3, Delta Ship 40, was christened "City of Atlanta" with a bottle of Coca-Cola. It went into scheduled service on December 24, 1940.
