Delta Tucanae A/B. Delta Tucanae (δ Tuc, δ Tucanae) is a common proper motion [3] pair located in the southwestern corner of the southern constellation of Tucana. [9] Based upon an annual parallax shift of 13.00 mas as seen from Earth, is approximately 250 light years from the Sun. It is visible to the naked eye with a combined apparent ...
Delta Boötis, Latinized from δ Boötis, is a double star in the northern constellation of Boötes, forming the easternmost member of the constellation's kite-shaped asterism of brighter stars. Based upon parallax measurements, it is located at a distance of approximately 121.8 light-years (37.3 parsecs ) from the Earth . [1]
Delta emarginatum is a species of potter wasp in the subfamily Eumeninae of the family Vespidae. Description. Delta emarginatum can reach a length of about 35 mm (1.4 in) in females. The males are smaller than the females. Distribution
Vortex lift works by capturing vortices generated from the sharply swept leading edge of the wing. The vortex, formed roughly parallel to the leading edge of the wing, is trapped by the airflow and remains fixed to the upper surface of the wing. As the air flows around the leading edge, it flows over the trapped vortex and is pulled in and down ...

Delta-matroid. In mathematics, a delta-matroid or Δ-matroid is a family of sets obeying an exchange axiom generalizing an axiom of matroids. A non-empty family of sets is a delta-matroid if, for every two sets and in the family, and for every element in their symmetric difference , there exists an such that is in the family. For the basis sets ...
