Voorbeeldzinnen

1. A random variable is definitely a constant if the variance is zero
2. N(x) denotes the cumulative distribution function for a standard normal random variable (i.e. the probability that a normal random variable with mean zero and variance of one is less than or equal to x).
3. N(x) denotes the cumulative distribution function for a standard normal random variable (i.e. the probability that a normal random variable with mean zero and variance of one is less than or equal to x). G (Z) denotes the inverse cumulative distribution function for a standard normal random variable (i.e. the value x such that N(x)= z).
4. N(x) denotes the cumulative distribution function for a standard normal random variable (i.e. the probability that a normal random variable with mean zero and variance of one is less than or equal to x). G (Z) denotes the inverse cumulative distribution function for a standard normal random variable (i.e. the value x such that N(x) z)
5. N(x) denotes the cumulative distribution function for a standard normal random variable (i.e. the probability that a normal random variable with mean zero and variance of one is less than or equal to x). G (Z) denotes the inverse cumulative distribution function for a standard normal random variable (i.e. the value x such that N(x) z) For PD = 0, RW shall be 0.
6. G (Z) denotes the inverse cumulative distribution function for a standard normal random variable (i.e. the value x such that N(x)= z).

8. In statistics the expected value (or mathematical expectation, or mean) of a random variable is the sum of the products of the value of each possible outcome multiplied by the probability of that outcome.
9. "Measurement uncertainty" (2) is the characteristic parameter which specifies in what range around the output value the correct value of the measurable variable lies with a confidence level of 95 %. It includes the uncorrected systematic deviations, the uncorrected backlash and the random deviations (ref. ISO 10360-2, or VDI/VDE 2617).
10. "Measurement uncertainty" (2) is the characteristic parameter which specifies in what range around the output value the correct value of the measurable variable lies with a confidence level of 95 %. It includes the uncorrected systematic deviations, the uncorrected backlash and the random deviations (ref. ISO 10360-2, or VDI/VDE 2617).

12. "Radar spread spectrum" (6) means any modulation technique for spreading energy originating from a signal with a relatively narrow frequency band, over a much wider band of frequencies, by using random or pseudo-random coding. "Real-time bandwidth" (3) for "dynamic signal analysers" is the widest frequency range which the analyser can output to display or mass storage without causing any discontinuity in the analysis of the input data. For analysers with more than one channel, the channel configuration yielding the widest "real-time bandwidth" shall be used to make the calculation. "Real time processing" (6 7) means the processing of data by a computer system providing a required level of service, as a function of available resources, within a guaranteed response time, regardless of the load of the system, when stimulated by an external event. "Repeatability" (7) means the closeness of agreement among repeated measurements of the same variable under the same operating conditions when changes in conditions or non-operating periods occur between measurements. (Reference: IEEE STD 528-2001 (one sigma standard deviation)) "Required" (GTN 1-9), as applied to "technology", refers to only that portion of "technology" which is peculiarly responsible for achieving or extending the controlled performance levels, characteristics or functions. Such "required""technology" may be shared by different goods. "Resolution" (2) means the least increment of a measuring device; on digital instruments, the least significant bit (ref. ANSI B-89.1.12).

"Riot control agent" (1) means substances which, under the expected conditions of use for riot control purposes, produce rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure. Technical Note: Tear gases are a subset of "riot control agents".

Non-metallic particles may be incorporated in the alloy by addition of the appropriate powders. "Melt Extraction" (1) means a process to 'solidify rapidly' and extract a ribbon-like alloy product by the insertion of a short segment of a rotating chilled block into a bath of a molten metal alloy. N.B.:'Solidify rapidly': solidification of molten material at cooling rates exceeding 1000 K/s.
