Tuple

A tuple is a finite ordered list of elements. In mathematics, an n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer. There is only one 0-tuple, an empty sequence. An n-tuple is defined inductively using the construction of an ordered pair. Tuples are usually written by listing the elements within parentheses "" and separated by commas; for example, denotes a 5-tuple. Sometimes other symbols are used to surround the elements, such as square brackets "[ ]" or angle brackets "< >". Braces "{ }" are never used for tuples, as they are the standard notation for sets. Tuples are often used to describe other mathematical objects, such as vectors. In computer science, tuples are directly implemented as product types in most functional programming languages. More commonly, they are implemented as record types, where the components are labeled instead of being identified by position alone. This approach is also used in relational algebra. Tuples are also used in relation to programming the semantic web with Resource Description Framework or RDF. Tuples are also used in linguistics and philosophy.

Single (football)

In Canadian football, a single (single point, or rouge), scoring one point, is awarded when the ball is kicked into the end zone by any legal means, other than a successful field goal, and the receiving team does not return, or kick, the ball out of its end zone. It is also a single if the kick travels through the end zone or goes out of bounds in the end zone without being touched, except on a kickoff. After conceding a single, the receiving team is awarded possession of the ball at the 35-yard line of its own end of the field.

Singles are not awarded in the following situations:

In all these cases the defending team is awarded possession of the ball at the 25-yard line.

In the United States, singles are not usually recognized in most leagues and are awarded only in matches played under the auspices of the National Indoor Football League (formerly United Indoor Football) and the now-defunct American Indoor Football Association. It is applied only on kickoffs in both leagues, and is scored if the receiving team fails to advance the ball out of the end zone when kicked. The NIFL also allowed a single to be scored by kicking a kickoff through the uprights (as in a field goal); this type of single is nicknamed (and has since been codified in the NIFL rules as) an uno, from the Spanish word for the number one. At one point, the Philadelphia Public League (the public high school football sanctioning body in Philadelphia, Pennsylvania) awarded three points for kicking a kickoff through the uprights.

Standard Performance Evaluation Corporation

The Standard Performance Evaluation Corporation (SPEC) is an American non-profit organization that aims to "produce, establish, maintain and endorse a standardized set" of performance benchmarks for computers.

SPEC was founded in 1988. SPEC benchmarks are widely used to evaluate the performance of computer systems; the test results are published on the SPEC website. Results are sometimes informally referred to as "SPECmarks" or just "SPEC".

SPEC evolved into an umbrella organization encompassing four diverse groups; Graphics and Workstation Performance Group (GWPG), the High Performance Group (HPG), the Open Systems Group (OSG) and the newest, the Research Group (RG). More details are on their website; .

Dose

Dose means quantity (in units of energy/mass) in the fields of nutrition, medicine, and toxicology. Dosage is the rate of application of a dose, although in common and imprecise usage, the words are sometimes used synonymously.

Dose can also mean quantity (in units of number/area) in the fields of Surface science and Ion implantation. See the definition of dose in ISO18115-1, term 4.173 (and compare the related definition of fluence in term 4.217 of the same Standard).
