Source defined

As a complication some sources define a flow index as the reciprocal of that defined above so that some care has to be taken in interpretation. In such cases the values are greater than unity for polymer melts and the greater the value the greater the divergence from Newtonian behaviour.)... [Pg.166]

Organic chemicals dissolved in groundwater originate from a release source, which may be point source (defined leak) or it may emanate from an area source, such as a mass of contaminated soil. Once dissolved, the chemicals disperse into the ground-water by molecular diffusion and advection (combined as dispersion), both of which are influenced by equilibrium distribution relationships with the aquifer materials. [Pg.342]

Second, the source of ions is geometrically broad compared with that in TIMS. Therefore, the extracted ions need to be spatially restricted and direction-ally focused at the source (defining) slit with minimal loss of transmission, in order for the mass resolved ion beams to fit easily within the openings of the multiple Faraday detectors (buckets) and produce excellent peak shape. [Pg.293]

Equation 11.20 describes the factorization of the experimental data matrix into two factor matrices, the loadings matrix VT and the augmented scores matrix Uau . The loadings matrix V1 identifies the nature and composition of the N main contamination sources defined by means of their chemical composition (SVOC concentrations)... [Pg.456]

Robustness is sometimes also called ruggedness in the literature, while other sources define both as different validation items. For instance, Youden and Steiner (6) use the term ruggedness (for robustness), the United States Pharmacopoeia (USP) (13) distinguishes between both terms and provides... [Pg.14]

The retina contains three classes of cells, known as L, M and S cones, that are responsible for colour vision and that are maximally sensitive to long-, medium-, and short-wavelength light in the visible spectrum. The relationship between the spectral reflectance i of a surface and the excitations e, (where i e L, M, S ) of the cones that occur when the snrface is viewed in a light source defined by a spectral power distribution E is often expressed by the eqnation... [Pg.65]

As is the case for all portable devices, power is scarce. Choice of power source defines a prosthesis, in that it determines the choice of actuator. If the power source is to be the person, i.e., body power, then the actuator is the person s own musculature and the prosthesis should not require excessive effort to use. Mechanical mechanisms need to be efficient and frictional losses need to be minimized to avoid tiring the user over the course of a day. If the artificial limb is externally powered (i.e., uses a power source other than the body, usually electric storage), the limb should be able to run for a day from the same power source without needing to be replaced or recharged. In addition, it is desirable for the power source to be contained within the prosthesis. [Pg.827]

Sources Define the kind of source of signal to the system (Figure 4.21). Sinks Results from the simulation (Figure 4.22). The last one, XY Graph, allows plotting graphs from the results of the calculation. [Pg.150]

Permitting is based on assessment of potential degradation of the environment, and thus both the level of emissions from the plant and the present level of contamination in the local environment are considered. There are National Ambient Air Quality Standards (NAAQS) for a few materials and National Emissions Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS) for these and others. Major sources (defined as those plants that emit more than some annual threshold quantity such as 25 tons of hazardous air pollutants) must meet the most stringent emissions criteria and require more permits. Similar standards are applied for water quality and for discharges into the water. Many of these regulations are based on the Clean Air Act and Clean Water Act, among others. [Pg.797]

The novel situation is found for tiie case ii) reactant and product channel electronic states have the same parity. Now, if the electronic Q-state sustains bound vibrational states, the stationary external Coulomb sources define a geometric arrangement around which the nuclei would fluctuate, These (nor-... [Pg.38]

Hudson s diamond x-k plot (a, c) and the skewed diamond u-v plot (b, d). The CLVD means the reversed CLVD axis. The dots in (a, b) show a regular grid in Ciso and Cclvd from —1 to +1 with step of 0.1. The dots in (c, d) show 3,000 sources defined by moment tensors with randomly generated eigenvalues. For scaling of the eigenvalues, see the text. Plots (c) and (d) indicate that the distribution of random sources is uniform in both projections... [Pg.1552]

More realistic sources are modeled in Fig. 8 the pure DC and ISO sources defined by tensors Edc and Ejso from Eq. 12 are contaminated by random noise with a uniform distribution in the interval from 0.25 to 0.25. The noise is superimposed to all tensor components and 1,000 random moment tensors are generated. As expected, the randomly generated source tensors form clusters, but their shape is different for different projections and their size depends also... [Pg.1555]

The dots show 1,000 DC sources defined by the elementary tensor Edc (see Eq. (12)) and contaminated by noise with a uniform distribution from —0.25 to 4-0.25. The noise is superimposed to all tensor components... [Pg.1556]
