Tolerance range

The statistical model makes use of the fact that the probability of all the components being at the extremes of their tolerance range is very low (see equation 3.2). The statistical model is given by ... 

The Canadian Clean Air Act allows the minister to formulate air quality objectives reflecting three ranges of ambient air quality for any contaminant. The tolerable range denotes a concentration that requires abatement without... 

As the overall fabricating tolerance is analyzed into the sources of its variation components, the potential advantage of analytical programs comes into play with their ability to efficiently process all these factors. All the empirical tolerance ranges for each tooling method and inspection method are stored in data files for easy retrieval. For each critical dimension the program sums all the com-... 

Output Errors. Output errors are analogous to input errors they can lead to biased parameter values or erroneous conclusions on the ability of the model to represent the natural system. As noted earlier, whenever a measurement is made, the possibility of an error is introduced. For example, published U.S.G.S. stream-flow data often used in hydrologic models can be 5 to 15% or more in error this, in effect, provides a tolerance range within which simulated values can be judged to be representative of the observed data. It can also provide a guide for terminating calibration efforts. 

It is usually convenient to identify the angles of the 10 most intense scattering peaks in a powder pattern, and to then list the accepted tolerance ranges of these based on the diffractometer used for the determinations. Such a representation has been developed for data obtained for racemic mandelic acid, and for its separated (S)-enantiomer, using a diffractometer system whose precision was known to be +0.15 degrees 26 [30]. The criteria are shown in Table 7.9, the form of which enables the ready identification of a mandelic acid sample as being either racemic or enantiomerically pure. It should be noted that the powder pattern of the separated (i )-enantiomer would necessarily have to be identical to that of the separated (S)-enantiomer. 

For each NOESY cross peak, one or several initial assignments are determined based on chemical shift fitting within a user-defined tolerance range. 

The uniform distribution specifies that the part is equally likely to have a value anywhere in the specified tolerance range. The first example we will look at is the 5% resistor model included in class.lib. If you look at Appendix E on page 620, you will see the following line in the file class.lib ... 

The AndlySlS is set up for Monte CdflO. The number of runs is 100. The AC Sweep will run 100 times. For each run, each part that has tolerance will have a value randomly chosen within its tolerance range. The Output VsUlUble is V( /0). Click the More Settings button ... 

We concluded that relatively low to moderate doses of either a high- or low-potency antipsychotic were sufficient to control acutely manic patients with associated psychotic features, and at these doses, adverse effects remained in the tolerable range. 

Thus, the tolerance range is mapped on to six standard deviations. 

A machine is mounted for production of metal rods 24 cm long, with a tolerance rate of = 0.05 cm. Based on long-time observation it is established that a = 0.03. On the assumption that lengths of X metal rods have a normal distribution calculate the percentage of metal rods that will be placed in tolerance range. How large should this tolerance be so that 95 per cent of produced metal rods should be within these tolerance limits ...
