Cupiagua Oil and Gas Field
Cupiagua is a giant oil and gas-condensate field in the Llanos foothills of Casanare, Colombia, discovered in 1993 by a BP-led consortium and operated by Ecopetrol since 2010, supplying a third of the country's natural gas.
Cupola (ISS module)
The Cupola is an ESA-built observatory module on the International Space Station, a seven-window dome installed in 2010 that gives crews a view of Earth and spacecraft.
Cupola furnace
A cupola furnace is a vertical shaft furnace used in foundries to melt cast iron, patented by John Wilkinson in 1794 and still in use today.
Cupra (marque)
Cupra, also known as SEAT Cupra, is a Spanish performance car marque created by SEAT within the Volkswagen Group, launched as a standalone brand in 2018 and headquartered at Martorell near Barcelona.
CUPRA Born
The CUPRA Born is a fully electric compact hatchback from CUPRA, SEAT's performance brand within Volkswagen Group, launched in 2021 as the brand's first electric model.
CUPRA Tavascan
The CUPRA Tavascan is CUPRA's all-electric SUV coupé, designed in Barcelona, built in China, and launched in 2024 as the brand's second electric model after the Born.
CuraWeb
CuraWeb is a 2026 data-curation framework for web-scale pretraining corpora that jointly optimizes quality, redundancy, and diversity, producing a 2T-token English corpus from twelve years of Common Crawl snapshots.
Curb
A curb, spelled "kerb" in British English, is a raised concrete or stone edge along a roadway that separates traffic from sidewalks and channels stormwater runoff.
Curb extension
A curb extension, also known as a bulbout or neckdown, is a traffic-calming treatment that widens the sidewalk into the parking lane to shorten pedestrian crossings.
Curexo
Curexo, Inc. is a South Korean medical robotics company in Seoul that develops surgical robots for joint replacement and spine surgery, CUVIS-joint and CUVIS-spine, and a gait rehabilitation robot called MorningWalk.
Curi
Curi is a humanoid mobile research robot used at the Georgia Institute of Technology for human-robot interaction studies, including contingency detection and affordance learning from human demonstration.
Curia Julia
The Curia Julia (Curia Iulia) is the senate house of ancient Rome in the Roman Forum, begun by Caesar and dedicated by Augustus in 29 BCE.
Curiosity (rover)
Curiosity is a car-sized robotic rover of NASA's Mars Science Laboratory mission, landed by sky crane in Gale crater on Mars in 2012, still exploring Mount Sharp.
Curiosity-driven exploration
Curiosity-driven exploration is a reinforcement learning approach where agents self-generate intrinsic reward from prediction error to explore when external rewards are sparse, notably via Berkeley's 2017 Intrinsic Curiosity Module.
Curiously recurring template pattern
The curiously recurring template pattern (CRTP) is a C++ idiom in which a class derives from a class template instantiated with itself, enabling compile-time polymorphism without virtual functions.
CURL
curl is a command-line tool for transferring data to or from a server using URLs, paired with the libcurl C library and led by Daniel Stenberg since 1996.
Curragh Coal Mine
The Curragh Coal Mine is a large open cut and underground coal mine in the Bowen Basin of Central Queensland, operating since 1983 and owned by Coronado Global Resources.
Current AI (nonprofit)
Current AI is a French nonprofit public-private partnership for public-interest AI, founded by Martin Tisné at the 2025 AI Action Summit in Paris with over $400 million pledged.
Current conveyor
The current conveyor (CC) is a three-port analog building block introduced in 1968 that conveys current to a high-impedance output, widely used in filters and oscillators.
Current matching
Current matching is the design condition in multi-junction solar cells where stacked sub-cells generate equal photocurrents, so none limits the others; it shapes perovskite/silicon tandem design.
Current mirror
A current mirror is an analog circuit block that copies a reference current at its input to an output, used widely for biasing and as amplifier loads.
Current source
A current source, also called a constant current source, is a circuit that delivers a specified current to a load regardless of the voltage across its terminals.
Current transformer
A current transformer (CT) is an instrument transformer that scales high primary currents down to standard values, typically 5 A or 1 A, for meters and protective relays.
Current-mode logic
Current-mode logic (CML) is a digital circuit technique that steers a constant current in a differential pair rather than swinging voltages, prized for speed and low noise in gigabit links.
Current-source converter
A current-source converter is a power electronic converter that holds a stiff DC current behind an inductor; in HVDC it is known as the line-commutated converter.
Current-voltage hysteresis
Current-voltage hysteresis is the discrepancy between forward and reverse current-voltage scans of a solar cell, characteristic of metal halide perovskite cells, caused mainly by ion migration and complicating efficiency measurement.
Current–voltage characteristic
A current–voltage characteristic, or I–V curve, is a graph of the electric current flowing through a device as a function of applied voltage, used to characterize diodes, transistors, and solar cells.
Curriculum learning
Curriculum learning is a machine learning training strategy that orders training examples from easy to difficult, formalized by Bengio and colleagues in 2009; gains are contested.
Curse of multilinguality
The curse of multilinguality is the decline in per-language performance of a multilingual language model as more training languages are added at fixed model capacity, named in the 2020 XLM-R paper.
Cursor (coding agent)
Cursor is an AI-native IDE and coding agent built by Anysphere as a fork of VS Code, first released in 2023, running on its own Composer models.
