In general, any measurable function can be pushed forward. The push-forward then becomes a linear operator, known as the transfer operator or Frobenius–Perron operator.In finite spaces this operator typically satisfies the requirements of the Frobenius–Perron theorem, and the maximal eigenvalue of the operator corresponds to the invariant measure.
When the yoke is pushed forward, the nose is lowered. When the yoke is turned left, the plane rolls to the left, and when it is turned to the right, the plane rolls to the right. Small to medium-size aircraft, usually limited to propeller-driven, feature a mechanical system whereby the yoke is connected directly to the control surfaces with ...
This spoon worm has a roughly cylindrical trunk between 70 and 110 mm (2.8 and 4.3 in) long. At the anterior end of the trunk, just beside the mouth, a scoop-shaped proboscis about 30 to 40 mm (1.2 to 1.6 in) long extends forward. The trunk has about 22 rings of papillae, a ring of larger papillae alternating with several rings of smaller papillae.
Let : be a smooth map of smooth manifolds. Given , the differential of at is a linear map : from the tangent space of at to the tangent space of at (). The image of a tangent vector under is sometimes called the pushforward of by .
The notion of pushforward in mathematics is "dual" to the notion of pullback, and can mean a number of different but closely related things.. Pushforward (differential), the differential of a smooth map between manifolds, and the "pushforward" operations it defines
Synonym for the verb "couple" used by brakemen when flat switching a yard. Talking on the radio, they will tell the engineer how many car lengths to back up in order to couple to another car (i.e. "five cars to a joint") [160] Joint bar (US) A metal plate that joins the ends of rails in jointed track Juice Train

Armadillo Aerospace's quad rocket vehicle showing shock diamonds in the exhaust plume from its propulsion system. Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid.
