Drum tablature, commonly known as a drum tab, is a form of simplified percussion notation, or tablature for percussion instruments.Instead of the durational notes normally seen on a piece of sheet music, drum tab uses proportional horizontal placement to indicate rhythm and vertical placement on a series of lines to represent which drum from the drum kit to stroke.
Algebraic notationis the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinatesto uniquely identify each square on the board.[1] It is now almost universally used by books, magazines, newspapers and software, and is the only form of notation recognized by FIDE, the international chess ...
The DOT code [ 1] is an alphanumeric character sequence molded into the sidewall of the tire and allows the identification of the tire and its age. The code is mandated by the U.S. Department of Transportation [ 2] but is used worldwide. [ 3] The DOT code is also useful in identifying tires subject to product recall [ 4] or at end of life due ...
Half-life (symbol t ½) is the time required for a quantity (of substance) to reduce to half of its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.
A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...
Activity relationship chart. An activity relationship chart (ARC) is a tabular means of displaying the closeness rating among all pairs of activities or departments. [1] In an ARC there are six closeness ratings which may be assigned to each pair of departments, as well as nine reasons for those ratings (each is assigned by a reason code).
Beryllium-10 ( 10 Be) is a radioactive isotope of beryllium. It is formed in the Earth's atmosphere mainly by cosmic ray spallation of nitrogen and oxygen. [ 3][ 4][ 5] Beryllium-10 has a half-life of 1.39 × 10 6 years, [ 6][ 7] and decays by beta decay to stable boron-10 with a maximum energy of 556.2 keV. It decays through the reaction 10 Be ...
In power engineering, a single-line diagram ( SLD ), also sometimes called one-line diagram, is a simplest symbolic representation of an electric power system. [ 1][ 2] A single line in the diagram typically corresponds to more than one physical conductor: in a direct current system the line includes the supply and return paths, in a three ...
