SCAM, the IEEE International Conference on Source Code Analysis and Manipulation, is an annual software engineering conference on automated analysis and manipulation of source code, founded in 2001.

Scammell

Scammell was a British manufacturer of commercial and military vehicles, based in Watford, Hertfordshire, from 1922 to 1988, known for heavy haulage tractors and the Mechanical Horse.

Scan chain

A scan chain is a shift register built from a digital chip's own flip-flops, letting test equipment control and observe internal state through a few pins.

Scan strategy control of crystallographic texture in selective laser melting

Scan strategy control of crystallographic texture is the deliberate choice of laser scan path, direction, and rotation in selective laser melting to control grain orientation and anisotropic properties.

Scan-rate-dependent hysteresis in perovskite solar cells

Scan-rate-dependent hysteresis in perovskite solar cells is the dependence of the measured current density–voltage curve on voltage sweep speed, widely attributed to slow ion migration in the absorber.

Scan-to-BIM

Scan-to-BIM is the process of converting 3D laser-scanned point clouds of existing structures into semantically enriched Building Information Models, used for renovation, facility management, heritage documentation, and digital twins.

Scandinavian Airlines

Scandinavian Airlines (SAS) is the flag-carrier airline group of Denmark, Norway, and Sweden, formed in 1946, flying from hubs in Copenhagen, Oslo, and Stockholm to destinations in Europe and overseas.

Scandinavian design

Scandinavian design is a term for design and applied craft from Denmark, Finland, Norway, and Sweden, coined in the 1950s and known for clear, functional shapes and natural materials.

Scandit

Scandit is a Swiss software company headquartered in Zurich that develops computer vision software letting smartphones, wearables, and fixed cameras scan barcodes for enterprise workflows in retail and logistics.

Scandlines

Scandlines is a privately owned ferry operator running two routes between Germany and Denmark, Puttgarden–Rødby and Rostock–Gedser, operating the world's largest fleet of hybrid ferries.

Scania AB

Scania AB, historically Scania-Vabis, is a Swedish manufacturer of heavy trucks, buses and coaches, and industrial and marine engines, founded in 1891 in Södertälje, Sweden.

Scanner (lithography)

A scanner, more fully a step-and-scan lithography system, is a semiconductor manufacturing machine that prints circuit patterns onto silicon wafers by sweeping light through a mask in synchronized motion.

ScanNet

ScanNet is an RGB-D video dataset of 2.5 million views in more than 1500 indoor scans, introduced by Stanford, Princeton, and TU Munich researchers at CVPR 2017.

Scanning electron microscope

A scanning electron microscope (SEM) forms images of a sample's surface by scanning a focused electron beam across it, and is used in materials science, semiconductor manufacturing, and biology.

Scanning probe lithography

Scanning probe lithography is a nanofabrication method that uses a scanning probe microscope tip to pattern material at nanometer scales, with resolution between 4 and 10 nm.

Scanning tunneling microscope

The scanning tunneling microscope is an instrument that images conductive surfaces with atomic resolution, invented by Gerd Binnig and Heinrich Rohrer at IBM Zurich in 1981.

Scapy

Scapy is a Python-based interactive packet manipulation program and library that can forge, send, sniff, and dissect packets of many network protocols, developed by Philippe Biondi starting in 2003.

SCARA

SCARA (Selective Compliance Assembly Robot Arm; Japanese スカラロボット) is a four-axis industrial robot, rigid vertically and fast horizontally, invented by Hiroshi Makino in Japan in 1978 and widely used in electronics assembly.

Scarborough Floating Production Unit

The Scarborough Floating Production Unit is a semi-submersible gas processing facility operated by Woodside Energy off Western Australia, which delivered first gas in July 2026.

Scarborough gas field

The Scarborough gas field is a deepwater natural gas field in the Carnarvon Basin, about 375 km off Western Australia's Pilbara coast, discovered in 1979 and developed by Woodside Energy.

Scarborough subway extension

The Scarborough subway extension, also called the Line 2 East Extension, is a 7.8-kilometer underground extension of Toronto's Line 2 subway from Kennedy Station to Sheppard Avenue East.

Scareware

Scareware, also known as rogue security software or FakeAV, is malware or a scam that uses fake virus alerts to trick users into paying for worthless security tools.

Scarlett Johansson–OpenAI voice dispute

The Scarlett Johansson–OpenAI voice dispute was a May 2024 controversy in which Scarlett Johansson said ChatGPT's "Sky" voice sounded "eerily similar" to hers, and OpenAI paused it.

Scarpa (company)

Scarpa is an Italian manufacturer of mountain footwear and ski boots based in Asolo, Veneto. Founded in 1938, it makes the Maestrale alpine touring ski boots.

SCART

SCART, also called Péritel or Euroconnector, is a 21-pin analog audio/video connector for consumer equipment, introduced in 1977 and standard in Europe until HDMI displaced it.

Scatec

Scatec, founded as Scatec Solar in 2007 and listed on the Oslo Stock Exchange in 2014, is a Norwegian renewable energy company building solar, wind, and hydropower plants in emerging markets.

SCATS (traffic management)

SCATS (Sydney Coordinated Adaptive Traffic System) is an adaptive traffic signal control system developed by the New South Wales Government in Australia in the mid 1970s and now owned by Transport for NSW.

Scatter search

Scatter search (SS) is a population-based evolutionary metaheuristic for optimization, introduced by Fred Glover in 1977, which combines solutions systematically rather than randomly as genetic algorithms do.

Scattering transform

The scattering transform, or wavelet scattering, is a fixed signal-processing method that cascades wavelet convolutions with modulus nonlinearities, with no learned parameters, used for texture, image, and audio classification.

Scatterometry

Scatterometry, also known as optical critical dimension (OCD) metrology, is a non-imaging optical technique that fits diffraction signatures from periodic nanostructure targets to models, measuring linewidth, height, and sidewall angle with nanometer precision in semiconductor fabrication.
