Scour protection

Scour protection is the set of engineering measures that prevent or limit erosion of sediment around structures founded in water, most commonly around offshore wind turbine foundations and bridge piers.

Scout (rocket family)

Scout was an American small orbital launch vehicle flown for NASA from 1960 to 1994, and in February 1961 it became the first entirely solid-propellant rocket to reach orbit.

Scout Terra

The Scout Terra is a full-size electric pickup from Scout Motors, unveiled in 2024 with up to 350 miles of range and production targeted for 2027.

Scram

A scram, also called a reactor trip, is the emergency shutdown of a nuclear reactor in which all control rods are rapidly inserted to stop the fission chain reaction.

Scramjet

A scramjet (supersonic combustion ramjet) is an airbreathing jet engine that burns fuel in supersonic airflow, pursued since the 1950s for hypersonic flight up to at least Mach 15.

Scrap

Scrap, or scrap metal, is discarded metal from parts, vehicles, and manufacturing waste that is collected and recycled as a major feedstock for steel and aluminum production.

Scrap preheating

Scrap preheating is a steelmaking technique in which ferrous scrap destined for an electric arc furnace is heated by the furnace's hot off-gases, saving about 60 kWh per ton.

Scratch (programming language)

Scratch is a free, block-based visual programming language for children, created at the MIT Media Lab and launched in 2007, now run by the Scratch Foundation.

Scratch test (coating adhesion)

The scratch test measures coating adhesion by drawing a diamond stylus across a coated surface under increasing force until the coating fails at a critical load.

Scratch testing

Scratch testing drags a diamond stylus across a coated surface under controlled load to measure coating adhesion and scratch hardness; the critical load marks coating failure.

Scratch-drive actuator

The scratch-drive actuator (SDA) is an electrostatic MEMS actuator, invented by Akiyama and Shono, whose flexible plate advances in small steps to produce linear motion.

ScratchJr

ScratchJr is a free, block-based introductory programming language and tablet app for children aged 5 to 7, inspired by Scratch and launched in July 2014.

A scratchpad is generated text in which a language model writes intermediate computation steps before its final answer, introduced in a 2021 paper by Maxwell Nye and coauthors.

Scratchpad memory

Scratchpad memory (SPM) is a small, software-managed on-chip memory with fixed access latency, used in DSPs, microcontrollers, GPUs, and AI accelerators as an alternative to cache.

Screed

A screed is a thin layer of cement-sand mortar or fine concrete applied over a floor slab to level it and receive the final flooring.
