Congestion control
Congestion control is how network senders regulate the amount of data injected into a network, implemented mostly in TCP and QUIC to prevent congestion collapse.
Congestion control algorithm
A congestion control algorithm is the sender-side mechanism a transport protocol uses to regulate its sending rate, responding to congestion signals such as packet loss or delay.
Congo LNG
Congo LNG is a two-phase floating liquefied natural gas project off the Republic of the Congo, operated by Eni on the Marine XII block and exporting since 2024.
Congressional inquiry into the Nvidia–Groq deal
The congressional inquiry into the Nvidia–Groq deal was opened by Senators Warren and Blumenthal in March 2026 over whether Nvidia's $20 billion deal evaded antitrust review.
Congressional Space Medal of Honor
The Congressional Space Medal of Honor, also known as the Space Medal of Honor, is the highest award the United States gives to astronauts, first presented in 1978.
Congreve rocket
The Congreve rocket was a British military rocket developed by Sir William Congreve at Woolwich from 1804, adapted from Indian Mysorean rockets and immortalized in 'The Star-Spangled Banner'.
Congruex
Congruex LLC is a Boulder, Colorado company, backed by Crestview Partners, that acquires and operates design, engineering, construction, and maintenance providers for broadband network and utility operators.
Conjugate action
Conjugate action is the property of meshing gear tooth profiles that transmit a constant angular-velocity ratio; the common normal at contact passes through the pitch point.
Conjugate cam
A conjugate cam, also called a complementary or double-disc cam, is a cam mechanism in which two paired disc cams drive a two-roller follower, maintaining contact without a spring.
Conjugate heat transfer analysis
Conjugate heat transfer analysis is a computational method solving heat conduction in a solid and convection in a fluid together, computing temperatures without a prescribed heat transfer coefficient.
Conjugated microporous polymer
A conjugated microporous polymer is an amorphous organic polymer combining a π-conjugated backbone with permanent microporosity, first reported in 2007 and applied in photocatalytic hydrogen evolution, gas storage, and sensing.
Conjugated microporous polymer photocatalysis
Conjugated microporous polymer (CMP) photocatalysis uses amorphous organic networks combining π-conjugation with permanent micropores as metal-free catalysts that convert solar energy into hydrogen, CO2 reduction products, and organic reactions.
Conjugated polymer
A conjugated polymer is a polymer whose backbone alternates single and multiple bonds, allowing π-electron delocalization that gives conductivity, underpinning organic solar cells, transistors, and LEDs.
Conjugated polymer photocatalysts for hydrogen evolution
Conjugated polymer photocatalysts for hydrogen evolution are organic semiconducting polymers whose backbones absorb light and reduce protons to hydrogen from water, tunable at the molecular level but limited by strong exciton effects.
Conjunction assessment
Conjunction assessment is the process of predicting close approaches between orbiting space objects, computing the risk of collision, and deciding whether an avoidance maneuver is needed. It is the operational core of satellite collision avoidance.
Connect Europe
Connect Europe, known until September 2024 as ETNO, is a Brussels-based trade association for Europe's telecom operators, advocating investment-friendly policy for networks such as fiber and 5G.
Connected Earth
Connected Earth is a UK telecommunications heritage initiative created by BT in 2002, a virtual museum plus eight partner museums caring for BT's collection of about 40,000 objects.
Connected Energy
Connected Energy is a British company headquartered in Newcastle upon Tyne that builds battery energy storage systems from second-life electric vehicle batteries, including its modular E-STOR product.
Connected Vehicle Pilot
The Connected Vehicle Pilot was a US Department of Transportation program begun in 2015 that funded connected vehicle deployments in Wyoming, New York City, and Tampa, Florida.
Connecticut Department of Transportation
The Connecticut Department of Transportation (CTDOT) is the state agency handling transportation planning, engineering, construction, and mass transit across Connecticut; it was established on October 1, 1969.
Connecticut Light and Power
Connecticut Light and Power (CL&P) is an investor-owned electric utility serving most of Connecticut, with about 1.28 million customers, operating as a direct subsidiary of Eversource Energy.
Connecticut Public Utilities Regulatory Authority
The Connecticut Public Utilities Regulatory Authority, or PURA, is the quasi-judicial state agency regulating Connecticut's investor-owned electric, gas, water, and telecommunications utilities, including Eversource and United Illuminating.
Connecticut Yankee nuclear power plant
Connecticut Yankee was a 619 megawatt pressurized water reactor at Haddam Neck in Haddam, Connecticut, which operated from 1968 until its permanent shutdown in December 1996.
Connecting Europe Facility
The Connecting Europe Facility (CEF) is an EU funding instrument, created in 2013, that supports transport, energy, and digital infrastructure projects with a €33.71 billion budget for 2021–2027.
Connecting rod
A connecting rod, also called a conrod or main rod, links a piston to a crankshaft, with a small end on the gudgeon pin and a big end on the crank-pin.
Connection Machine
The Connection Machine is a family of massively parallel supercomputers built by Thinking Machines Corporation between 1983 and 1994, in the models CM-1, CM-2, and CM-5.
Connectionist temporal classification
Connectionist temporal classification (CTC) is an objective function, introduced by Alex Graves and colleagues in 2006, for training neural networks to label unsegmented input sequences directly, first used widely in speech recognition.
ConnectU
ConnectU, originally HarvardConnection, was a college social networking website founded by Harvard students Divya Narendra and the Winklevoss twins, known for its lawsuit against Facebook.
