  U.S. Patent: 5221113 - Male and female screw threads, more especially for pneumatic equipment - June 22, 1993
The number of threads per inch in the taper section is in a range between the nominal values of the cylindrical thread section and of an NPT thread with the same size.
The number of threads per inch in the axial direction in the case of the cylindrical thread section 1 is in accordance with the associated thread nominal size, that is to say in the present case 19 threads per inch.
The number of threads per inch of the taper thread section 2 is in a range between the nominal value for the cylindrical thread section 1 and the nominal value for the NPT with the same nominal thread size.

  Nominal number - Wikipedia, the free encyclopedia
The properties of nominal numbers are the minimum required to refer to an entity as a number.
The term "nominal number" is quite recent, and appears to have originated as a usage in school textbooks derived from the statistical term "nominal data", defined as data indicating "...[m]erely statements of qualitative category of membership."
Sport jersey numbers may be a true example of nominal numbers, but it is difficult to tell whether they truly are, since it is in general unclear what policies are used by clubs to allocate them.

 LINGUIST List 12.1074: Corbett, Number
Number is an area of morphosyntactic typology that has often been taken for granted by linguistic researchers.
A good portion of this chapter is devoted to distinguishing verbal number from agreement with nominal arguments, for example Huichol (Uto-Aztecan) has singular and plural verb stems depending on the number of the "participant most directly affected" by the situation described by the verb.
Other topics treated in chapter nine are the interaction between number and other nominal categories (e.g., gender, obviation, definiteness, case and person), the acquisition of number, and the psycholinguistics of number, and how number marking is deployed in various languages.

Phi thus measures the strength of the relationship defined as the number of cases on one diagonal minus the number on the other diagonal, adjusting for the marginal distribution of the variables.
Cramer's V is the most popular of the chi-square-based measures of nominal association because it gives good norming from 0 to 1 regardless of table size, when row marginals equal column marginals.
Specifically, lambda is the surplus of errors made when the marginals of the dependent variable are known, minus the number of errors made when the frequencies of the dependent variable are known for each class (value) of the independent variable, as a percentage of errors of the first type.

The nominal data series is simply the data measured in current dollars and gathered by a government or private survey.
Then the 1995 nominal value is divided by the ratio of the 1995 price index and the 1990 price index to arrive at a real value (or the 1995 value in 1990 dollars).
Nominal: The value of an economic variable in terms of the price level at the time of its measurement; or, unadjusted for price movements.

 Nominal distance
A nominal or categorical variable is used when number is only a symbol to represent something.
If the number of category is more than two, we need to transform these categories into a set of dummies variables that has binary value.
The distance between two objects is the ratio of number of unmatched and total dummy variables.

The definition given in the book tells us that cardinal numbers tell how many (12 shirts per box), ordinal numbers tell position or order (1st place, 5th in line) and nominal numbers name things (number on a jersey, a telephone number).
It's just a real number, no other designation needed (except for some purposes one wants to know that pi is not an "algebraic number" but is a "transcendental" number).

 Accumulator roller synchronization with image size adjustment - Patent 5450114
The stepper motor is driven from the output of the counter during the period of a fixed number of sweep pulses.
Since the stepper motor pulses are periodically overridden by the sweep pulses at a given fixed number, the number of control pulses to the stepper motor defined by the count need only be an integral number within the period of the fixed number.
This can be explained as being the nominal number corrected for the observed difference from nominal operation, which is high speed clock frequency divided by sweep frequency, modified by the difference from nominal, which is number of stepper motor pulses to be applied during 200 sweep pulses.) The number of oscillations is a comparison number.

 Cardinal number Summary
In mathematics, cardinal numbers, or cardinals for short, are a generalized kind of number used to denote the size of a set.
Each algebraic number may be encoded as a finite sequence of integers which are the coefficients in the polynomial equation of which it is the solution, i.e.
It is possible to use a different formal notion for number, called ordinals, based on the ideas of counting and considering each number in turn, and we discover that the notions of cardinality and ordinality are divergent once we move out of the finite numbers.

Number is the most underestimated of the grammatical categories.

 Serial number - Wikipedia, the free encyclopedia
A serial number is a unique number that is one of a series assigned for identification which varies from its successor or predecessor by a fixed discrete integer value.
If there are items whose serial numbers is part of a sequence of consecutive numbers and you take n number of random samples of items' serial numbers, you can then estimate the population of items "in the wild" using a maximum likelihood method derived using Bayesian reasoning.
Serial numbers are often used in network protocols.

 Nominal number
The properties of nominal numbers are the minimum required to refer to an entity as a number.
A Nominal number is a numeral, or a string of numerals that is used for identification only, so that the only valid operation that may be carried out with nominal numbers is comparison.
That is, two or more nominal numbers can be compared to determine if they are identical; while this may seem trite, it is a distinction important for computer science.

The number of electrons in an atom is normally equal to the number of protons in the nucleus.
The nominal mass of an atom of an element is measured by the sum of the protons and neutrons in it.
It should be noted that the emission of gamma rays does not change the mass number or atomic number of the nucleus -- that is, unlike radioactive decay by emission of particles, spontaneous fission, or electron capture, it does not cause the transmutation of the nucleus into another element.

We speak of a nominal number when we use number as a name, such as the number on a football or basketball jersey.
Inasmuch as a nominal number is essentially a label, young children can use nominal numbers as soon as they are able to use names, usually by age two or three.
To understand a unit the child must grasp the idea that, for example, the number three is both like every other number used in counting (its cardinal meaning) but also different from every other number (its ordinal meaning), because it is the only number that comes after two and before four.

An investigation was conducted to determine the temperature recovery factors for laminar boundary layer on a cone at free stream Mach numbers from 5.6 to 5.9.
For this range of Reynolds numbers the recovery factor was found to be independent of the Reynolds number.
The square root of the Prandtl number evaluated at the mean of the temperatures of the cone surface for the various flow conditions investigated was found to be less than one per cent lower than the mean of the experimental temperature recovery factors.

The maximum acceptable number of errors depended upon the configuration of the panel (number of nominal concentrations and number of replicates at each).
Like FDD errors, the maximum acceptable number of TDU errors depended upon the configuration of the panel (number of nominal concentrations and number of replicates at each) and the rate of TDU errors was based on the same samples that are used to calculate the intra-assay SD.
The maximum acceptable number of negative results was then number that would be exceeded no more than 5% of the time, given the number of samples involved and assuming independent binomial sampling with an underlying probability of a negative result of 0.05.

Sumerian makes use of both nominal postpositions and verbal infixes to code the information that is generally subsumed under case-marking.
There are three nominal cases that should probably be categorized as core or grammatical in nature: the zero-marked absolutive/nominative case, the ergative case-marking postposition /*-e/, which is formally identical with the locative-terminative case-marking postposition, and the genitive case-marking postposition /*-a/.

The number distinction in a given language is expected to affect a top segment of the Animacy Hierarchy (speaker/1person > addressee/2person > 3person > kin > human > animate > inanimate).
Having established the number values which languages may have, on the one hand, and the possible patterns of involvement in the number system, on the other hand, the author combines those two aspects in Chapter 4 ("Integrating number values and the Animacy Hierarchy", pp.
265-298) a variety of further topics is dealt with, including the diachronic rise and decline of number, the interactions with other grammatical categories like gender, case, person, definiteness, the use of number with respect to frequency and irregularity, the acquisition and the psycholinguistics of number.

As discussed in the previous section, the Euclidean distance function is inappropriate for nominal attributes, and VDM is inappropriate for continuous attributes, so neither is sufficient on its own for use on a heterogeneous application, i.e., one with both nominal and continuous attributes.
We hypothesized that as the number of output classes grows, the normalization would get worse for N3 if it was indeed not appropriate to add the scaling factor C to the sum.
As the number of output classes grows, the difference for N3 between the linear distances and the nominal distances grows wider in most cases.
