Flash smelting
Flash smelting is a smelting process in which fine, dry sulfide concentrates react while suspended in hot, oxygen-enriched air. Developed by Finland's Outokumpu in the 1940s, it is the dominant primary copper smelting technology.
Flash spark plasma sintering
Flash spark plasma sintering (FSPS), also called flash hot pressing (FHP), combines flash sintering with spark plasma sintering to densify hard-to-sinter ceramics in seconds with limited grain growth.
Flash steam geothermal power
Flash steam geothermal power is the most widely used geothermal technology, flashing pressurized hot water above 182°C into steam to drive turbines; a double flash variant yields 15–25% more power.
Flash translation layer
A flash translation layer (FTL) is SSD firmware that makes NAND flash behave like a conventional block device through address translation, wear-leveling, and garbage collection.
FlashAttention
FlashAttention is an IO-aware algorithm for computing exact transformer attention on GPUs, introduced by Tri Dao and collaborators in a NeurIPS 2022 paper, that never materializes the quadratic attention matrix in main memory.
Flasher origami pattern
The flasher is an origami pattern, designed by Jeremy Shafer and Chris Palmer, that collapses a circular sheet into a compact bundle and is used in deployable space structures.
FlashEx (闪送) (Shansong)
FlashEx (闪送, Shansong) is a Beijing-based on-demand same-city courier company founded in 2014, known for its one-courier-per-order model and its Nasdaq listing in October 2024.
FlashInfer
FlashInfer is an open-source kernel library for large language model inference, providing attention, GEMM, and mixture-of-experts operators that serving engines like vLLM and SGLang use as a backend.
Flashing beacon
A flashing beacon is a highway traffic signal that operates in a flashing mode rather than a normal red-yellow-green sequence, controlling intersections or warning drivers.
Flashlight
A flashlight, also called an electric torch, is a hand-held, battery-powered portable light, named for the brief flashes of weak early models before household adoption around 1910.
Flask (web framework)
Flask, also known as Python Flask, is a lightweight Python web framework created by Armin Ronacher. First released in 2010, it is a microframework that leaves databases and forms to extensions.
Flat Display Mounting Interface
The Flat Display Mounting Interface, also known as the VESA mount, is a VESA standard defining mounting hole patterns and screws for attaching flat displays to stands, arms, and wall mounts.
Flat engine
A flat engine, also called a horizontally opposed engine, is a piston engine with two cylinder banks on either side of a central crankshaft. It powers almost all small aircraft built since World War II.
Flat Glass Group
Flat Glass Group (福莱特) is a Chinese glass manufacturer founded in 1998 and headquartered in Jiaxing, Zhejiang, one of the world's largest producers of photovoltaic glass for solar modules.
Flat Rock Assembly Plant
Flat Rock Assembly Plant, formerly the Ford-Mazda joint venture AutoAlliance International, is a Ford assembly plant in Flat Rock, Michigan, near Detroit, that builds the Ford Mustang.
Flat roof
A flat roof is a nearly horizontal roof made watertight by a continuous membrane and sloped about 2 to 25 percent to drains, typical on commercial buildings.
Flat-field correction
Flat-field correction is an image-processing step that removes uneven illumination, vignetting, dust shadows, and pixel-to-pixel sensitivity differences so intensities can be compared across an image.
Flat-four engine
A flat-four engine is a four-cylinder engine with horizontally opposed cylinder banks on either side of the crankshaft, giving smooth balance and a low center of gravity.
Flat-panel display
A flat-panel display is a thin, lightweight electronic screen that forms images from pixels, replacing bulky cathode-ray tubes; LCD, plasma, and OLED are the main technologies.
Flat-plate collector
A flat-plate collector is a non-concentrating solar thermal collector in which a flat, glazed absorber plate heats a circulating fluid, used for domestic water heating and space heating.
Flat-six engine
The flat-six engine, also known as H6 or boxer six, is a six-cylinder piston engine best known for powering Porsche 911, Subaru vehicles, and general aviation aircraft.
Flat-twin engine
A flat-twin engine, often called a boxer, is a two-cylinder engine with opposed cylinders, patented by Karl Benz in 1896 and best known from BMW motorcycles.
Flatbed truck
A flatbed truck is a truck or tractor-trailer with a completely open, flat cargo deck, loaded by crane or forklift and used for steel, lumber, and pipe.
FlatBuffers
FlatBuffers is an open-source binary serialization library released by Google in 2014, letting programs read data directly from the buffer without parsing or extra memory allocation.
Flatcar
A flatcar, also called a flat wagon, is a railroad freight car consisting of a flat deck with no sides, ends, or roof, carrying weather-tolerant cargo.
Flathead engine
The flathead engine, also called a side-valve or L-head engine, has valves in the engine block, not the cylinder head, and dominated motoring into the 1950s.
Flatiron Building
The Flatiron Building, officially the Fuller Building, is a triangular 22-story skyscraper at 175 Fifth Avenue in Manhattan, New York City, completed in 1902 to a design by Daniel Burnham.
FlatSat
A FlatSat is an electrical model of a satellite with its subsystems laid out side by side on a workbench, giving engineers direct access to buses and components.
Flaviu Cristian
Flaviu Cristian (1951–1999) was a computer scientist who worked on fault-tolerant distributed systems at IBM and UC San Diego, best known for Cristian's algorithm for clock synchronization and for atomic broadcast.
Flechette
A flechette (French fléchette, "little arrow") is a dartlike steel projectile that wounds by kinetic energy alone; first air-dropped in 1914, it remains in use, including in Ukraine.
