Machine learning in materials science
Machine learning in materials science, often called materials informatics, uses models trained on materials data to predict properties, screen candidates, and guide synthesis and processing.
Machine learning nonlinearity compensation
Machine learning nonlinearity compensation is the use of machine learning, chiefly neural networks, to reverse nonlinear signal distortion in optical fiber systems, mostly Kerr-effect distortion that limits long-haul transmission distance and capacity.
Machine pistol
A machine pistol is a pistol-style firearm capable of fully automatic or burst fire, firing pistol cartridges. Early examples appeared in Europe before 1918, and the best-known service example is the Soviet Stechkin APS.
Machine taper
A machine taper is a standardized conical fitting that locates and holds tools on machine tool spindles, either self-holding by friction or self-releasing with a drawbar.
Machine to machine
Machine to machine (M2M) is direct communication between devices over a network with little or no human intervention, for tasks such as metering, monitoring, or control.
Machine tool
Machine tool: stationary power-driven machine that shapes metal and other materials by cutting, grinding, forming, or EDM; also called werkzeugmaschine. Key facts: JIS B 0105 excludes hand-held tools; tolerances to ±0.0025 mm; lathes, mills, machining centers, grinders; 'machines that produce machines.'
Machine translation
Machine translation (MT) is software that converts text or speech between natural languages without human translation; since the mid-2010s it has been dominated by neural approaches, following rule-based and statistical eras.
Machine unlearning
Machine unlearning is a family of techniques for removing specific knowledge or capabilities from a trained model's weights without retraining, pursued mainly as an AI safety method.
Machine vision
Machine vision is the industrial use of computer vision, combining cameras, lighting, sensors, and software to automate quality inspection, defect detection, and robotic guidance on production lines.
Machine vision for in situ monitoring of additive manufacturing
Machine vision for in situ monitoring of additive manufacturing uses cameras and machine-learning algorithms to detect melt pool behavior and defects during 3D printing in real time.
Machine-check exception
A machine-check exception is an x86 processor exception, delivered as interrupt 18, that tells the operating system the CPU detected a hardware error such as a bus, cache, or ECC error.
Machine-learning-designed metasurfaces
Machine-learning-designed metasurfaces are planar optical structures whose subwavelength meta-atoms are found by neural networks rather than manual design, enabling inverse design of lenses, holograms, and other devices.
Machine-learning-guided alloy discovery
Machine-learning-guided alloy discovery uses machine learning models, often combined with physics simulations and automated experiments, to search vast alloy composition spaces for targeted properties, most developed for high-entropy alloys where trial-and-error search is impractical.
Machine-readable passport
A machine-readable passport (MRP) is a passport whose biodata page carries a scannable Machine Readable Zone, defined by ICAO Doc 9303 and required of all countries since 2010.
Machining
Machining, also known as machine cutting, is a subtractive manufacturing process that removes material from a solid workpiece by controlled cutting, abrasion, or erosion, producing parts such as turbine blades and engine components.
Machining center
A machining center is a numerically controlled machine tool that performs milling, boring, and tapping, changing tools automatically from a magazine under program control; the first was Kearney & Trecker's Milwaukee-Matic of 1958.
Machinist
A machinist is a skilled industrial worker who sets up and operates machine tools, such as lathes, milling machines, and grinders, to produce precision metal parts, instruments, and tools.
Machiya
Machiya (町家) are traditional Japanese wooden town houses of merchants and artisans, built on narrow urban plots; the Kyoto examples, kyo-machiya, once housed much of the city's population.
Macintosh 128K
The Macintosh 128K, also known as the original Apple Macintosh, is the compact personal computer Apple released on January 24, 1984, the first commercially successful mouse-driven graphical-user-interface computer.
Macintosh Classic II
The Macintosh Classic II is an all-in-one compact Macintosh personal computer introduced by Apple in 1991, sold until 1993 and also rebadged as the Performa 200.
Macintosh File System
Macintosh File System (MFS) is the flat, single-directory file system Apple created for the original Macintosh, released in January 1984, and the predecessor of HFS.
Macintosh II
The Macintosh II is a modular personal computer Apple introduced in 1987 as the first expandable, color-capable Macintosh, with a Motorola 68020 processor and six NuBus expansion slots.
Macintosh Performa
Macintosh Performa, also called Mac Performa, was Apple Computer's consumer Macintosh line sold from September 1992 to August 1997, mostly renamed existing models sold through mass-market retailers.
Macintosh Plus
The Macintosh Plus, also known as Mac Plus, is an all-in-one personal computer released by Apple in January 1986, sold until 1990, making it the longest-produced Macintosh model.
Mack Trucks
Mack Trucks is an American manufacturer of medium- and heavy-duty trucks, founded in 1900 by Jack and Gus Mack and owned by the Volvo Group since 2001.
Mackensen-class battlecruiser
The Mackensen class was a class of four battlecruisers laid down in 1915 for the Imperial German Navy, armed with eight 35 cm guns; none was ever completed.
Mackerel Oil and Gas Field
Mackerel is an offshore oil field in the Gippsland Basin of Bass Strait off Victoria, Australia, discovered in 1969 and producing through the Mackerel platform since 1977.
Mackinac Bridge
The Mackinac Bridge, known as the Mighty Mac, is a suspension bridge opened in 1957 that connects Michigan's two peninsulas across the Straits of Mackinac.
MACOM Technology Solutions
MACOM Technology Solutions is an American semiconductor company headquartered in Lowell, Massachusetts, that designs and makes analog RF, microwave, millimeter wave, and optical chips, trading on Nasdaq as MTSI.
MacOS
macOS, formerly Mac OS X and then OS X, is Apple's operating system for Mac computers, first released in 2001 on a Unix-based Darwin core.
