High-leg delta. High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank).
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 ...
Dyke Delta. The Dyke Delta JD-2 is an American homebuilt aircraft designed in the United States in the 1960s and marketed for amateur construction. It is a monoplane with retractable tricycle undercarriage and seating for four. The wings can be folded for towing or storage and hinge upwards to lie flat above the fuselage, one atop the other. [1]
Δ−. (ddd), which respectively carry an electric charge of +2 e, +1 e, 0 e, and −1 e . The Δ baryons have a mass of about 1 232 MeV/c2; their third component of isospin and they are required to have an intrinsic spin of 3 2 or higher (half-integer units). Ordinary nucleons (symbol N, meaning either a proton or neutron ), by contrast, have ...
The Mississippi Delta, also known as the Yazoo–Mississippi Delta, or simply the Delta, is the distinctive northwest section of the U.S. state of Mississippi (and portions of Arkansas and Louisiana) that lies between the Mississippi and Yazoo rivers. The region has been called "The Most Southern Place on Earth" [1] ("Southern" in the sense of ...
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 ...
18. O. In geochemistry, paleoclimatology and paleoceanography δ18O or delta-O-18 is a measure of the deviation in ratio of stable isotopes oxygen-18 ( 18 O) and oxygen-16 ( 16 O). It is commonly used as a measure of the temperature of precipitation, as a measure of groundwater/mineral interactions, and as an indicator of processes that show ...
