A pulse detonation engine ( PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. [1] [2] The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed ...
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics .
Booking Holdings Inc. is an American travel technology company incorporated under Delaware General Corporation Law and based in Norwalk, Connecticut, that owns and operates several travel fare aggregators and travel fare metasearch engines including namesake and flagship Booking.com, Priceline.com, Agoda, Kayak, Cheapflights, Rentalcars.com, Momondo, and OpenTable.
Pulse generators are available for generating output pulses having widths (duration) ranging from minutes to under 1 picosecond. Pulse generators are generally voltage sources, with true current pulse generators being available only from a few suppliers. Pulse generators may use digital techniques, analog techniques, or a combination of both ...
Pulse-width modulation ( PWM ), also known as pulse-duration modulation ( PDM) or pulse-length modulation ( PLM ), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period ). PWM is useful for controlling the average power or amplitude delivered by an electrical signal.
PULSE is a P2PTV application developed by the European FP7 NAPA-WINE (Network-Aware P2P-TV Application over Wise Networks) research consortium. PULSE stands for Peer-to-Peer Unstructured Live Streaming Experiment and is a peer-to-peer live streaming system designed to operate in scenarios where the bandwidth resources of nodes can be highly ...
Pulse dialing is a signaling technology in telecommunications in which a direct current local loop circuit is interrupted according to a defined coding system for each signal transmitted, usually a digit. This lends the method the often used name loop disconnect dialing. In the most common variant of pulse dialing, decadic dialing, each of the ...
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn ), or 1 km in 2.91 s or one mile in 4.69 s. It depends strongly on temperature as well as the medium through which a ...
