Stroke order refers to the order in which the strokes of a Chinese character are written. A stroke is a movement of a writing instrument on a writing surface. Certain stroke orders guidelines are recommended to ensure speed, accuracy, and legibility in composition, as most Chinese characters have many strokes. As such, teachers enforce exactly ...

The compression stroke is the second of the four stages in a four-stroke engine. In this stage, the air-fuel mixture (or air alone, in the case of a direct injection engine) is compressed to the top of the cylinder by the piston. This is the result of the piston moving upwards, reducing the volume of the chamber.

A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake: Also known as induction or suction.This stroke of the piston begins at top dead center (T.D.C.) …

The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS), is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke.The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is …

Collation is the assembly of written information into a standard order. Many systems of collation are based on numerical order or alphabetical order, or extensions and combinations thereof.Collation is a fundamental element of most office filing systems, library catalogs, and reference books.. Collation differs from classification in that the classes themselves are not …

Đ (lowercase: đ, Latin alphabet), known as crossed D or dyet, is a letter formed from the base character D/d overlaid with a crossbar.Crossing was used to create eth (ð), but eth has an uncial as its base whereas đ is based on the straight-backed roman d. [clarification needed] Crossed d is a letter in the alphabets of several languages and is used in linguistics as a phonetic symbol.

A "twingle" is a four-stroke twin-cylinder engine with an altered firing order designed to give power pulses similar to a single-cylinder four-stroke engine.. Inline twins with a 360° crankpin offset or flat-twins can be easily converted into twingles by firing both of the cylinders at the same time and installing a camshaft or camshafts that operate both cylinders' valves in parallel.

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms.It is the moving component that is contained by a cylinder and is made gas-tight by piston rings.In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston …

The Fairy Feller's Master-Stroke is a painting by English artist Richard Dadd.It was begun in 1855 and worked on until 1864. Dadd painted it while incarcerated in the State Criminal Lunatic Asylum of Bethlem Royal Hospital, where he was confined after he murdered his father in 1843. It was commissioned by George Henry Haydon, who was head steward of the hospital at the time.

First-order logic—also known as predicate logic, quantificational logic, and first-order predicate calculus—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science.First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables, so that rather than propositions such as "Socrates …
