Same limit rule

The Same Limit Rule is used when a large number of results violate the specification. In this case we choose a new target which is violated by a reasonable proportion of results. The resulting change in the mean is given by... [Pg.378]

The fact that several representations are possible automatically necessitates the development of rules which would allow a researcher to decide upon a preferred representation. To this end, lUPAC has developed an elaborate rules-based system using the seniority of subunits , the direction of citation, etc. [65]. However, rules-based systems are subject to the same limitations as nomenclature systems in that they, too, suffer from (potential) historical discontinuities and require acceptance by a broad community. [Pg.118]

Rotational features of almost aU H-bonded complexes in the gaseous phase appear in the microwave region, with wavenumbers less than 10 cm They correspond to transitions between pure rotational levels, pure meaning that vibrations remain unchanged, or no vibrational transition accompanies such rotational transitions. Rotational features, however, also appear in the IR spectra of these H-bonded complexes. IR bands correspond to transitions between various vibrational levels of a molecule. When this molecule is isolated, as in the gas phase, these transitions are always accompanied by transitions between rotational levels that obey the same selection rules as pure rotational transitions detected in microwave spectroscopy. The information conveyed by these rotational features in IR spectra are therefore most similar to those conveyed by microwave spectra, even if the mechanism at the origin of their appearance is different. Their interests lie in the use of an IR spectrometer, a common instrument in many laboratories, instead of a microwave spectrometer, which is a much more specialized instrament. However, the resolution of usual IR spectrometers are lower than that of microwave spectrometers that use Fabry-Perot cavities. This IR technique has been used in the case of simple H-bonded dimers with relatively small moments of inertia, such as, for instance, F-H- -N C-H (3). Such complexes are far from simple to manipulate, but provide particularly simple IR spectra with a limited number of bands that do not show any overlap. [Pg.55]

The thermodynamic limit to the stability of sterically stabilized emulsions was investigated by March and Napper (1977). It would be expected that in this limit, both oil-in-water and water-in-oil emulsions would obey the same general rules as are observed for sterically stabilized latices (Phillips, 1975). [Pg.120]

The answer is C. By increasing the amoxmt of aluminum used by the first student, there will not be an increase in the yield because Fe O is the limiting reagent. Hence, Choice A is not correct. The same reasoning rules out Choice B. Increasing the amount of Fe Oj by the second student will... [Pg.410]

The dissolving power of solvent mixtures follows the same general rules and a mixture of properly selected liquids, which each by themselves merely give rise to limited swelling, may be a solvent Numerous examples were already well known from practice. In such cases two critical solubility limits will exist. [Pg.559]

The example shows, that a fault can be detected based on a fast detection of deviations of the characteristic features as well as the analysis of their values with heuristic rules. As soon as the value of a feature is not within its limits rules will produce a hypothesis that a certain disturbance has been detected (symptom recognition). The presence of a hypothesis activates additional rules to diagnose the cause of the disturbance and to verify or falsify the hypothesis. The recognition of symptoms caused by faults is the ultimate goal of the knowledge-based system, so it can alarm the operator immediately. However, the analysis of the symptoms and the identification of the specific faults is also of great importance. A fundamental problem is to distinguish between faults that reveal themselves in the same or in similar symptoms. [Pg.139]

For transitions between two excited states, p) and g), the transition dipole moment is given by eqn (8.31), with the same selection rules as in the weak-coupling limit. [Pg.123]

The characters of the one-dimonsional species must satisfy the same multiplication rules as the group operations. In particular, this observation immediately limits the possible characters of C2 to 1. In the case of the cyclic groups, C , it was found that xc was an nth root of unity, d his must likewise be true in the dihedral groups, but sincMJ C and belong to the same class. [Pg.364]

We can treat an important but more complicated case that we will use to justify formulas we merely memorize later but we need to be aware of a process called integration by parts, which makes use of definite integration. Consider the integral that is the reverse process of the product derivative rule. Simply put, we wrap a definite integration process around the product mle formula, that is, we perform the definite integration term by term on both sides of the product equation and use the same limits on all the terms. Note that d(UV) = UdV+VdUdoes not have the dx denominator. This form of a derivative of just the numerator is called the differential and is valid for whatever variable is in the denominator. This concept is often used in thermodynamics. [Pg.495]

The column with i/s6h values demonstrates that only a fraction of the maximum available surface participates in the H2 oxidation. Otherwise the factor of 10 by which i/sQu differs for FC 100 and SM 2 should have a greater effect on the values of the ratio i/(Pt content). While the electrode CAAl has a similar porosity as the electrodes SM 2 and SM 1 and about the same mean hydraulic diameter as SM 1, its thickness is about half the thickness of the other electrodes and the ratio (Pt con-tent)/sQH is the smallest. The same limiting current and the same current-potential curve were obtained [12] when several thicknesses of electrode were compressed and used as one electrode. This result rules out any effect of the thickness on performance and suggests [12] in connection with the small ratio (<0.05) between the double layer capacity of the same electrode under diffusion conditions and in the flooded state for elec-... [Pg.248]

The intended use of a chemical probe will necessarily dictate its desirable characteristics. Probes of cellular processes used for epistatic perturbations will be subject to some of the same limitations of an in vivo probe of zebrafish developmental patterning however, drug metabolism and pharmacokinetic (DMPK) parameters essential for the action of an in vivo probe used in mouse or rat will not necessarily apply to the function of a cellular probe. Indeed, these differences will alter priorities for the beneficial characteristics of an in vitro probe when compared to an in vivo probe. For example, Lipinski s rule of five remains a central tenet of medicinal chemistry in drug discovery which serves as a useful limit of molecular characteristics for the development of orally bioavailable drugs, and while these guidelines generally describe preferable probe molecule properties, the rule of five may be... [Pg.210]

The same rules apply to precision control charts with the exception that there are no lower warning and lower control limits. [Pg.721]
