The template common metric prefixes creates an infobox that lists the most commonly used metric prefixes. The list is a subset of the list in the 8th edition of the official brochure of the BIPM (SI units and prefixes).
Nevertheless, the problem becomes fixed-parameter tractable when restricted to interval graphs, [7] and more generally to graphs of bounded tree-length, [9] such as chordal graphs, permutation graphs or asteroidal-triple-free graphs. Deciding whether the metric dimension of a tree is at most a given integer can be done in linear time [10] Other ...
Multiples and submultiples of metric units are related by powers of ten and their names are formed with prefixes. This relationship is compatible with the decimal system of numbers and it contributes greatly to the convenience of metric units. In the early metric system there were two base units, the metre for length and the gram for mass. The ...
Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [1] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers.
Thus metric spaces together with metric maps form a category Met. Met is a subcategory of the category of metric spaces and Lipschitz functions. A map between metric spaces is an isometry if and only if it is a bijective metric map whose inverse is also a metric map. Thus the isomorphisms in Met are precisely the isometries.
In this system, the basic units were the mão-travessa (hand) = 1 decimetre (10 mão-travessas = 1 vara (yard) = 1 metre), the canada = 1 litre and the libra (pound) = 1 kilogram. [61] In the Netherlands , 500 g is informally referred to as a pond ( pound ) and 100 g as an ons ( ounce ), and in Germany and France, 500 g is informally referred ...
A commonly used metric alternative is known as metres of development or rollout distance, which specifies how many metres a bicycle travels per revolution of the crank. Typical gear ratios on bicycles range from very low or light gearing around 20 gear inches (1.6 metres per revolution), via medium gearing around 70 gear inches (5.6 m), to very ...
Chordal graphs are precisely the graphs that are both odd-hole-free and even-hole-free (see holes in graph theory). Every chordal graph is a strangulated graph , a graph in which every peripheral cycle is a triangle, because peripheral cycles are a special case of induced cycles.
