Continuous descent approach
A continuous descent approach (CDA) is an aircraft arrival technique in which a plane descends from cruise to the runway with mostly idle thrust, saving fuel and cutting noise.
Continuous duty overnight
A continuous duty overnight, or "stand-up" overnight, is an airline trip sequence flown through the night with a crew rest break too short to count as rest.
Continuous extrusion
Continuous extrusion is a metal-forming process in which friction from a rotating wheel drives unheated rod or powder through a die continuously, best known as the Conform process.
Continuous fermentation
Continuous fermentation is a bioprocess method that feeds fresh medium into a bioreactor at a constant rate while withdrawing equal culture, sustaining steady-state microbial production.
Continuous galvanizing
Continuous galvanizing is an industrial process in which steel strip passes in an unbroken coil through molten zinc, applying a protective coating continuously; it dominates zinc-coated sheet for automotive body panels, appliances, and construction.
Continuous integration
Continuous integration (CI) is a software development practice in which developers merge work into a shared codebase at least daily, verified by automated builds and tests.
Continuous liquid interface production
Continuous liquid interface production (CLIP) is a 3D printing method that cures photosensitive resin continuously against a liquid interface, reported in Science in 2015 and commercialized by Carbon.
Continuous miner
A continuous miner is an underground mining machine that cuts coal or soft rock from the face and loads it onto an onboard conveyor without blasting.
Continuous stirred-tank reactor
A continuous stirred-tank reactor (CSTR), also called a perfectly stirred reactor, is a reaction vessel with an impeller that continuously blends feed, keeping composition and temperature uniform; sizes range from 1 mL to above 10 m³.
Continuous testing
Continuous testing is a software engineering practice that runs automated tests at every stage of the delivery pipeline, so each change gets immediate feedback on whether a release candidate is safe to proceed.
Continuous Tone-Coded Squelch System
The Continuous Tone-Coded Squelch System (CTCSS), also called PL tone, is a two-way FM radio method in which a subaudible tone keeps a receiver muted until it detects the programmed tone.
Continuous track
A continuous track, also called a caterpillar track or tank tread, is a system of vehicle propulsion that spreads weight over an endless band instead of wheels.
Continuous wave
A continuous wave (CW) is an uninterrupted radio signal at a single frequency, used for telegraphy and broadcasting, first generated by alternators and arc transmitters after 1900.
Continuous welded rail
Continuous welded rail (CWR) is railway track in which rails are welded end to end into very long strings, eliminating the bolted fishplate joints of older jointed track.
Continuous-flow manufacturing
Continuous-flow manufacturing is a method in which materials are fed into, transformed within, and removed from an integrated production line without interruption, replacing batch processing.
Continuous-phase modulation
Continuous-phase modulation (CPM) is a digital modulation method that encodes data in a carrier's continuously varying phase, producing a constant-envelope signal used in GSM and telemetry.
Continuously Operating Reference Station
A Continuously Operating Reference Station (CORS) is an automated GNSS receiver at a precisely surveyed location that records satellite data around the clock for high-accuracy positioning.
Continuously reinforced concrete pavement
Continuously reinforced concrete pavement (CRCP) is concrete road pavement with continuous longitudinal steel reinforcement and no intermediate transverse joints; its cracks are a designed feature, first tested in 1921.
Continuously variable transmission
A continuously variable transmission (CVT) is an automatic transmission that uses two pulleys joined by a belt or chain to change gear ratios continuously, improving fuel economy.
Continuum kinematics
Continuum kinematics is the mathematical description of how actuator inputs relate to the shape or end-effector pose of a continuum robot, which bends smoothly rather than at discrete joints.
Continuum robot
A continuum robot is a robotic manipulator with a continuously bending, flexible backbone instead of rigid joints, able to navigate tight spaces and grasp varied objects.
CONTOUR
CONTOUR (Comet Nucleus TOUR) was a NASA Discovery Program spacecraft launched in 2002 to fly by comet nuclei including 2P/Encke, lost six weeks after launch.
Contour following guidance
Contour following guidance, also called contour navigation, is an AGV navigation method that steers by matching LiDAR scans against a stored map instead of floor-installed guide paths.
Contour matching navigation
Contour matching navigation is a natural navigation method for automated guided vehicles that localizes by matching scanned wall, rack, and machinery profiles against a map.
Contour method (residual stress measurement)
The contour method is a destructive residual stress measurement technique that maps stress over a full cross-section by cutting a part in two and measuring the deformed surfaces.
Contourlet transform
The contourlet transform is a multiscale, multidirectional image decomposition built from a Laplacian pyramid and directional filter bank, introduced by Do and Vetterli in 2005 and used in denoising, compression, and fusion.
Contra Dam
The Contra Dam, also called the Verzasca Dam, is a 220 m high arch dam on the Verzasca River in Ticino, Switzerland, built from 1960 to 1965.
Contra-rotating propellers
Contra-rotating propellers are a pair of propellers mounted one behind the other on the same axis, turning in opposite directions so the rear one recovers swirl energy as thrust.
Contract lifecycle management
Contract lifecycle management (CLM) is the process of digitally managing agreements with customers, vendors, and partners through every stage, and the software platforms that automate it; the market reached about $2.9 billion in 2023.
Contract manufacturer
A contract manufacturer is a company that produces goods on behalf of another company, to that company's specifications, owning plant and workforce but bearing no selling risk.
