Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. [1] For example, cereal crops like maize or sorghum are often infested by stem borers. Grasses planted around the perimeter of the crop attract and trap the pests, whereas other plants, like Desmodium ...
However, the push–pull amplifier requires a phase-splitting component that adds complexity and cost to the system; use of center-tapped transformers for input and output is a common technique but adds weight and restricts performance. If the two parts of the amplifier do not have identical characteristics, distortion can be introduced as the ...
A push–pull train with two control cars and a locomotive in the middle. Push–pull is a configuration for locomotive -hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not. A push–pull train has a locomotive at one end of the train, connected via some form of remote control ...
Crossover distortion is a type of distortion which is caused by switching between devices driving a load. [1] It is most commonly seen in complementary, or "push-pull", class-B amplifier stages, although it is occasionally seen in other types of circuits as well. The term crossover signifies the "crossing over" of the signal between devices, in ...
Open outputs configurations thus differ from push–pull outputs, which use a pair of transistors to output a specific voltage or current. These open outputs configurations are often used for digital applications when the transistor acts as a switch , to allow for logic-level conversion, wired-logic connections , and line sharing.
Pusher configuration. The Wright Flyer, a “pusher” aircraft designed in 1903. In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of air- or watercraft with propulsion device (s) after the engine (s). This is in contrast to the more conventional tractor configuration, which places them in front.
Drafting (aerodynamics) A paceline of drafting cyclists. Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can ...
