In electrical engineering, the Y-Δ transform, also written wye-delta and also known by many other names, is a mathematical technique to simplify the analysis of an electrical network. The name derives from the shapes of the circuit diagrams , which look respectively like the letter Y and the Greek capital letter Δ .
Delta Tau Delta was founded at Bethany College, Bethany, Virginia, (now West Virginia) in 1858. The fraternity currently has around 130 collegiate chapters and colonies nationwide, with an estimated 10,000 undergraduate members and over 170,000-lifetime members.

Delta added jet airliners to its fleet in the 1960s; the Douglas DC-8 entered service in September 1959. Delta's new red, white, and blue triangle logo (the "widget") on their aircraft represented the jet's swept wing, as well as the Greek letter delta. [32] Convair 880s were added in 1960 (they set a coast-to-coast record) [33] and in 1965 the ...
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).
Mississippi Delta – green line marks boundary. 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.
Mathematically, if the change in the numerator is similar to the change in the denominator, the delta ratio will be close to 1. Since the anions are unable to diffuse out of the bloodstream, while bicarbonate and hydrogen ions diffuse with ease (as H 2 CO 3, carbonic acid), the usual result will be closer to a delta ratio of 1 to 2.
Delta Air Lines Flight 1086 was a scheduled Delta Air Lines domestic passenger flight between Atlanta and New York's LaGuardia Airport. On March 5, 2015, the McDonnell Douglas MD-88 aircraft veered off the runway shortly after landing at LaGuardia Airport in New York City .
