Plains West Coast Pipeline
The Plains West Coast Pipeline is a California crude oil pipeline system operated by Plains Pipeline, moving oil from Santa Barbara and the San Joaquin Valley to Los Angeles refineries.
PlainTalk
PlainTalk was the collective name for Apple Computer's classic Mac OS speech technologies, featuring speech recognition, text-to-speech synthesis, and a speech interface codenamed Casper, introduced in 1993.
Plamuk Oil and Gas Field
Plamuk Oil and Gas Field (ปลาหมึก, Thai for "squid") is an offshore oil and gas field in the Gulf of Thailand, discovered in 1996 and operated by Chevron.
Plan 9 from Bell Labs
Plan 9 from Bell Labs, also called Plan Nine from Bell Labs, is a distributed research operating system developed at Bell Labs from the late 1980s.
Plan for Development and Operation (Norway)
A plan for development and operation (PDO, Norwegian plan for utbygging og drift) is the document Norwegian petroleum licensees must submit for approval before developing a deposit.
Plan-and-execute agents
A plan-and-execute agent is an AI agent architecture in which a planner model breaks a goal into steps, an executor carries them out, and a replanner revises on failure.
Planar heterojunction perovskite solar cells
A planar heterojunction perovskite solar cell is a photovoltaic device with a flat perovskite film between electron and hole transport layers, without a porous scaffold.
Planar parallel manipulator
A planar parallel manipulator is a closed-loop mechanism that moves a platform in one plane with two translations and one rotation, three degrees of freedom at most.
Planar process
The planar process is a semiconductor manufacturing method, developed by Jean Hoerni at Fairchild Semiconductor between 1957 and 1959, that became the foundation of high-volume integrated circuit manufacturing.
Planar separator theorem
The planar separator theorem states that any n-vertex planar graph can be divided by at most 2√(2n) separator vertices, found in linear time by Lipton and Tarjan's 1979 algorithm.
Planar transformer
A planar transformer is a transformer whose primary and secondary windings are flat copper traces etched on a printed circuit board, used in compact, high-frequency power converters.
Planarity testing
Planarity testing, also called graph planarity, is the algorithmic problem of deciding whether a graph can be drawn without crossing edges, solvable in linear time since 1974.
Plane (tool)
A plane, also called a hand plane, is a woodworking hand tool with a sharpened blade in a flat-soled body that shaves thin layers from wood to flatten or smooth it.
Plane of array irradiance
Plane of array (POA) irradiance is the solar radiation, in watts per square meter, that strikes a photovoltaic array's tilted surface, differing from horizontal irradiance through tilt, azimuth, and tracking.
Plane wave expansion method
The plane wave expansion (PWE) method is a numerical technique that expands wave fields in plane waves, converting periodic-medium equations into matrix eigenvalue problems to compute photonic band structures.
PlaneSense
PlaneSense is a fractional aircraft ownership program based at Portsmouth International Airport in New Hampshire. Founded by George Antoniadis in 1995, it flies the Pilatus PC-12 and PC-24.
Planet (locomotive)
Planet was an 1830 2-2-0 steam locomotive built by Robert Stephenson & Co. for the Liverpool and Manchester Railway, the first with horizontal inside cylinders, the standard locomotive layout.
Planet 51
Planet 51 is a 2009 computer-animated sci-fi comedy from Spain's Ilion Animation Studios, directed by Jorge Blanco, Javier Abad, and Marcos Martínez, reversing E.T.: a human astronaut lands on a 1950s-style alien world that fears invasion. Budget $70 million; worldwide gross about $105.6 million.
Planet Labs
Planet Labs PBC is an American earth observation company founded in 2010 by three former NASA scientists, operating roughly 200 imaging satellites that photograph the whole Earth daily.
Planetes (プラネテス)
Planetes (プラネテス) is a hard science fiction manga by Makoto Yukimura, serialized from 2000, about working-class astronauts who collect hazardous space debris in Earth orbit.
PlanetLab
PlanetLab is a global network of computers used as a testbed for networking and distributed systems research. Established in 2002, it is hosted by universities and corporations worldwide.
PlanGrid
PlanGrid is a San Francisco construction software company founded in 2011, whose mobile app let contractors view and mark up project plans; Autodesk acquired it in 2018.
Planing (boat)
Planing is the mode in which a boat's weight is carried by hydrodynamic lift from its hull's motion rather than buoyancy, letting it exceed displacement speed limits.
Planing hull
A planing hull is a boat hull supported at speed by dynamic water lift on its flat or V-shaped bottom, unlike a displacement hull capped by hull speed.
Plank flooring
Plank flooring is wood flooring made of boards 3 inches wide or wider, giving a more casual look than narrower strip flooring, and also covers vinyl and laminate planks.
Plank house
A plank house is a dwelling of cedar posts, beams, and split planks built by Indigenous peoples of the Pacific Northwest Coast, used as winter homes and meeting houses.
Planned obsolescence
Planned obsolescence, also called built-in or programmed obsolescence, is the strategy of shortening a product's useful life so customers must replace it sooner, exemplified by the 1925 Phoebus lightbulb cartel.
Planning game
The planning game is the planning practice of Extreme Programming, a structured negotiation where customers prioritize user stories and programmers estimate effort, combining business value with cost.
Planning poker
Planning poker, also called Scrum poker, is a consensus estimation technique where agile team members privately choose cards, reveal them together, and discuss until they converge.
