Errors, clipping

Note that a number of complicating factors have been left out for clarity For instance, in the EMF equation, activities instead of concentrations should be used. Activities are related to concentrations by a multiplicative activity coefficient that itself is sensitive to the concentrations of all ions in the solution. The reference electrode necessary to close the circuit also generates a (diffusion) potential that is a complex function of activities and ion mobilities. Furthermore, the slope S of the electrode function is an experimentally determined parameter subject to error. The essential point, though, is that the DVM-clipped voltages appear in the exponent and that cheap equipment extracts a heavy price in terms of accuracy and precision (viz. quantization noise such an instrument typically displays the result in a 1 mV, 0.1 mV, 0.01 mV, or 0.001 mV format a two-decimal instrument clips a 345.678. .. mV result to 345.67 mV, that is it does not round up ... 78 to ... 8 ). 

It also avoids rectification errors (no-symmetrical clipping) in signal conditioning electronics.

If the rubber is less dense than water, a less dense liquid of known density could be substituted but it is more usual to attach a sinker to the test piece. The sinker can conveniently be a small piece of lead, but using an item like a paper clip to suspend the test piece leads to complications as it will only be partly submerged. The weight of the sinker in water must be measured and it is a common error among inexperienced technicians to make this weighing in air.

In this depiction, the typical trumpet form (A, E) of the c.o.v./CL curves is seen the fact that there is a spread toward the right-hand edge (C) suggests that the measurement errors grow in a slightly over-proportional fashion with the concentration. The narrowing down of the "trumpet at the lowest concentration (D) is a sign that due to the proximity to the LOD, the measurement distribution is not truly Gaussian but has the low side clipped. The data points for the lowest concentration (10 ng/ml) are off scale (-r31.2 -r65.9), while the fourth-smallest con-...

A new molecular entity exhibiting one-compartment pharmacokinetics with first-order absorption was assumed. The typical (mean) values of the population PK parameters for the NME were 1 h 17.5L/h, and SOL for absorption rate constant (Ka), apparent clearance (CLIP), and apparent volume of distribution (V/F), respectively. An intersubject variability of 45% (coefficient of variation) was assumed for each of these parameters, and this was assumed to be lognormally distributed with a mean of zero. A proportional error model was assumed for the residual error of 15%. 

Systemic deficiencies in the design. This is where the design lends itself to a tendency for maintenance errors to be realised. An example might be the potential for incorrect connection of duplicated components due to inadequate cable clipping or insufficient provision of different electrical connector keyways. These vulnerabilities could be obtained from conducting the CMA (see Chapter 6) on each zone. 

The most famous exercise in this respect was to be Thomas Edwards Gangraem or a catalogue and discovery of many of the errors, heresies, blasphemies and pernicious practices of the Sectaries, which was published in three parts in 1646, beginning in February. But there were already other books attacking Independents and Sectaries, by authors like William Prynne and John Bastwick (puritan martyrs who had had their ears clipped in 1639 by the bishops) and by Robert Baillie, a Scots commissioner in London. 

It is also important to monitor the mixing of all of the events and tracks in a project in an objective way by watching the Mixer window as a project is played back or as events are previewed. By visually monitoring the project in the Mixer window, you can prevent clipping errors that may ruin a song. The Mixer window (see Figure 2.28) is one of two windows that is visible by default when ACID is first run (the Explorer window is the other). If it is not visible, from the View menu, select Mixer or press Alt + 3.
