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 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 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 .
First run. c.1909. Major applications. Avro 500. Vickers F.B.9 Gunbus. Variants. Oberursel U.I. The Gnome 9 Delta was a French designed, nine-cylinder, air-cooled rotary aero engine that was produced under license in Britain. Powering several World War I era aircraft types it produced 100 hp (75 kW) from its capacity of 16 litres (980 cu in).
The flight engineer, Nicholas Nestor "Nick" Nassick, age 43, had been a Delta Air Lines employee since 1976. He had logged 6,500 hours of flight time, including 4,500 in the TriStar. Nassick had served with the U.S. Air Force from 1963 to 1976 and fought in four tours in the Vietnam War. : 92 Fellow Delta employees described him as "observant ...
Logarithmic mean temperature difference. In thermal engineering, the logarithmic mean temperature difference ( LMTD) is used to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers. The LMTD is a logarithmic average of the temperature difference between the hot and cold feeds at each end of ...
