They believe the definition of r is invalid because there is no well-defined notion of when an English phrase defines a real number, and so there is no unambiguous way to construct the sequence r < sub > n </ sub >.

The standard also defines a sequence of repeating code values which defines the power level of 0 dB.

A nonlinear recurrence relation defines successive terms of a sequence as a nonlinear function of preceding terms.

In mathematics, a recurrence relation is an equation that recursively defines a sequence, once one or more initial terms are given: each further term of the sequence is defined as a function of the preceding terms.

In the opening sequence of Seven Beauties, spoken over World War II archival footage showing the destruction of cities and men, Wertmüller defines the object of her critique — a " particular petty bourgeois social type.

An order is part of a sequence of patterns which defines the layout of a song.

The operation is described by the following equation, which defines the output sequence y in terms of its input sequence x:

For example, ISO-8859-1 states that no defining escape sequence is needed and RFC 1922, which defines ISO-2022-CN, allows ISO-2022 SHIFT characters to be used without explicit use of escape sequences.

A sequence of functions,, with being constant, defines an implementable policy of the decision process.

CIF defines a video sequence with a resolution of 352 × 288 like PAL Source Input Format, a framerate of 30000 / 1001 ( roughly 29. 97 ) frames like NTSC, with colour encoded using YCbCr 4: 2: 0.

When the historian encounters a situation in which he can perceive no visible cause and effect sequence, he should be alert to intuition and unconscious instinct as possible guides.

The 34 arrows, denoting onset age plus completion age deviations, have been arrayed in an Onset sequence which begins with girl 18 who had the earliest Onset of the 34 girls.

When the same sequence is equivalent in meaning to I have instructions which I am to leave, dominant stress is ordinarily on instructions.

to this he glued and fitted other pieces of paper and four taut strings, thus creating a sequence of flat surfaces in real and sculptural space to which there clung only the vestige of a picture plane.

This type of presentation is usually accomplished with a camera and a projector or a computer viewing screen which can rapidly cycle through images in a sequence.

While each scene has its own character and completeness it must fit into the general sequence to which it belongs.

If the method is applied to an infinite sequence ( X < sub > i </ sub >: i ∈ ω ) of nonempty sets, a function is obtained at each finite stage, but there is no stage at which a choice function for the entire family is constructed, and no " limiting " choice function can be constructed, in general, in ZF without the axiom of choice.

* There exists a model of ZF ¬ C in which there is a function f from the real numbers to the real numbers such that f is not continuous at a, but f is sequentially continuous at a, i. e., for any sequence

There is certainly a case for saying that Crooked House ( 1949 ) and Ordeal by Innocence ( 1957 ), which are not Poirot novels at all but so easily could have been, represent a logical endpoint of the general diminution of Poirot himself within the Poirot sequence.

Within an expression containing two or more occurrences in a row of the same associative operator, the order in which the operations are performed does not matter as long as the sequence of the operands is not changed.

They are descended from the Hindu-Arabic numeral system developed by Indian mathematicians, in which a sequence of digits such as " 975 " is read as a numeral.

Two results which follow from the axiom are that " no set is an element of itself ," and that " there is no infinite sequence ( a < sub > n </ sub >) such that a < sub > i + 1 </ sub > is an element of a < sub > i </ sub > for all i. "

Whenever the observer's learning process ( which may be a predictive neural network-see also Neuroesthetics ) leads to improved data compression such that the observation sequence can be described by fewer bits than before, the temporary interestingness of the data corresponds to the number of saved bits.

When 301 of the most advanced model, the " Launch Arco ," are built, an " exodus sequence " starts in which all Launch Arcos blast into space.

AZ were undefeated in all 32 of their home matches in European competitions, a sequence which ran from 1977 until 20 December 2007, when they finally lost to Everton of England by a score of 3 – 2.

This exon encodes a portion of the mature TNF domain, as well as the leader sequence which is a highly conserved region necessary for proper intracellular processing.

By sweeping this surface through R < sup > 3 </ sup > as a function of the ion sequence input data, such as via ion-ordering, a volume is generated onto which positions the 2D detector positions can be computed and placed three-dimensional space.

The canonical feature of atom probe data its high spatial resolution in the direction through the material, which has been attributed to an ordered evaporation sequence.

A related concept is that of a perfect number, which is a number which equals the sum of its own proper divisors, in other words a number which forms an aliquot sequence of period 1.

In data transmission systems a byte is defined as a contiguous sequence of binary bits in a serial data stream, such as in modem or satellite communications, which is the smallest meaningful unit of data.

The exact chemical composition and the sequence in which these units are arranged is called the primary structure, in the case of proteins.

The convention for a nucleic acid sequence is to list the nucleotides as they occur from the 5 ' end to the 3 ' end of the polymer chain, where 5 ' and 3 ' refer to the numbering of carbons around the ribose ring which participate in forming the phosphate diester linkages of the chain.
