Intelsat VI
Intelsat VI was a series of five Hughes geostationary communications satellites launched between 1989 and 1991, at the time the largest commercial satellites ever built.
Intensity-modulation direct detection
Intensity-modulation direct detection (IM-DD) is the simplest optical communication scheme: the transmitter varies a light source's power with the data signal, and a photodiode converts it back to current.
Intensity–duration–frequency curve
An intensity–duration–frequency (IDF) curve gives the rainfall intensity expected for a given storm duration and recurrence interval, guiding design of urban drainage and flood defenses.
Intent classification
Intent classification, also called intent detection or intent recognition, is an NLU task that assigns a user's utterance to one intent label, such as book_flight, which maps to a system action.
Intent prediction (robotics)
Intent prediction in robotics is a robot's inference of a human collaborator's unobserved goal or next action from cues such as motion, gaze, gestures, and speech.
Intentionally blank page
Intentionally blank page (vacat page, German Vakatseite): a page marked "This page intentionally left blank", inserted for signature counts, recto chapter starts, or error reassurance; earliest known phrase use circa 1922.
Inter (typeface)
Inter is a free and open-source sans-serif typeface designed by Rasmus Andersson for computer screens and user interfaces, first released in 2017 under the SIL Open Font License.
Inter Pipeline
Inter Pipeline is a Calgary-based Canadian energy infrastructure company owning oil sands pipelines, natural gas liquids processing, and petrochemical assets in Alberta, acquired by Brookfield Infrastructure in 2021.
Inter RAO
Inter RAO (ПАО «Интер РАО») is a Russian energy holding company, founded in 1997, that serves as Russia's only electricity exporter and importer and operates about 31.2 GW of generation.
Inter-area oscillation
An inter-area oscillation is a low-frequency oscillation in a large power grid where geographically separate generator groups swing against each other across weak transmission links, limiting power transfer.
Inter-process communication
Inter-process communication (IPC), also known as interapplication communication, is the mechanisms an operating system provides for processes to exchange data, using pipes, message queues, shared memory, and sockets.
Interaction design
Interaction design (IxD) is the design of how users interact with products, chiefly digital ones like apps and websites, aiming to help users achieve their objectives.
Interaction matrix
The interaction matrix, also called the image Jacobian, is the matrix in image-based visual servoing that maps camera velocity to the rate of change of image features such as points.
Interactive Disassembler
The Interactive Disassembler, sold as IDA Pro, is a programmable disassembler and debugger developed by Hex-Rays in Liège, Belgium, and created by Ilfak Guilfanov, supporting over 60 processor families.
Interactive genetic algorithm
An interactive genetic algorithm is a genetic algorithm in which a human user evaluates candidate solutions instead of a fitness function, applied to art, music, and design tasks.
Interactive machine learning
Interactive machine learning (IML) is an approach in which users iteratively build and refine a model through rapid, focused, incremental cycles of input and review.
Interactive machine translation
Interactive machine translation (IMT) is a mode of computer-assisted translation in which a human translator and a machine translation system build the target text together, with the system re-predicting after each edit.
Interactive voice response
Interactive voice response, known as IVR or an audio response unit, is a computerized phone system where callers interact with menus using keypads or speech.
Interactive whiteboard
An interactive whiteboard is a large touch-sensitive board connected to a computer and projector, first commercialized by SMART Technologies in 1991 and common in classrooms.
Interactivity
Interactivity in web user interfaces is the property of content that responds to user input by changing state or performing an action, resting on keyboard operability, DOM events, and user activation.
InteraXon
InteraXon is a Canadian neurotechnology company founded in Toronto in 2007 that makes the Muse line of consumer EEG headbands for meditation, neurofeedback, and sleep tracking.
Interball
Interball (ИНТЕРБОЛ) was a Russian-led program of four spacecraft in two pairs, launched in 1995 and 1996, that studied plasma processes in Earth's magnetosphere and solar wind.
INTERBUS
INTERBUS is a fieldbus, an industrial serial data network introduced by German company Phoenix Contact in 1987 to connect sensors, actuators, and controllers in production automation.
INTERCAL
INTERCAL, short for Compiler Language With No Pronounceable Acronym, is a parody programming language designed at Princeton University in 1972, regarded as the original esoteric programming language.
Intercalation pseudocapacitance
Intercalation pseudocapacitance is a charge-storage mechanism in which ions insert into the bulk of an electrode at capacitor-like rates, named in 2013 from studies of lithium ions in niobium pentoxide.
Intercarrier interference cancellation
Intercarrier interference cancellation covers signal-processing techniques that suppress intercarrier interference in OFDM systems, where mobile reception, carrier frequency offset, or phase noise destroy subcarrier orthogonality.
Intercarrier interference self-cancellation
Intercarrier interference self-cancellation (ICI self-cancellation) is a signal-processing technique for OFDM systems, introduced by Zhao and Häggman in 2001, that spreads each data symbol over adjacent subcarriers so their interference cancels.
Intercept message
An intercept message is a recorded telephone announcement played to callers whose dialed number cannot be completed because it was changed, disconnected, or never assigned.
Interceptor aircraft
An interceptor aircraft, also called an interceptor fighter, is a fighter built for speed and climb to intercept enemy aircraft, trading agility and range for the mission.
Interceptor drone
An interceptor drone is an unmanned aerial vehicle that flies toward a hostile drone and stops it in the air, most often with a net or by ramming.
