While a good equivalent-circuit representation of the transport processes in a fuel cell can lead to an increased understanding, it is not as good as taking a 1-D sandwich model and taking it into the frequency domain. These models typically analyze the cathode side of the fuel cell. °2.3i3 3i4 pj g j ost comprehensive is probably that of Springer et al. °2 The use of impedance models allows for the calculation of parameters, like gas-phase tortuosity, which cannot be determined easily by other means, and can also allow for the separation of diffusion and migra-... 

Abstract. Investigation of P,T-parity nonconservation (PNC) phenomena is of fundamental importance for physics. Experiments to search for PNC effects have been performed on TIE and YbF molecules and are in progress for PbO and PbF molecules. For interpretation of molecular PNC experiments it is necessary to calculate those needed molecular properties which cannot be measured. In particular, electronic densities in heavy-atom cores are required for interpretation of the measured data in terms of the P,T-odd properties of elementary particles or P,T-odd interactions between them. Reliable calculations of the core properties (PNC effect, hyperfine structure etc., which are described by the operators heavily concentrated in atomic cores or on nuclei) usually require accurate accounting for both relativistic and correlation effects in heavy-atom systems. In this paper, some basic aspects of the experimental search for PNC effects in heavy-atom molecules and the computational methods used in their electronic structure calculations are discussed. The latter include the generalized relativistic effective core potential (GRECP) approach and the methods of nonvariational and variational one-center restoration of correct shapes of four-component spinors in atomic cores after a two-component GRECP calculation of a molecule. Their efficiency is illustrated with calculations of parameters of the effective P,T-odd spin-rotational Hamiltonians in the molecules PbF, HgF, YbF, BaF, TIF, and PbO. 

The calculation of parameters of overcompressed wave formed on detonation of 2H2+O2 mixture, has shown that upon transition from the wide pipe to the narrow one, an overcompressed wave should arrise in the narrow pipe for which the pressure is 1.36 times greater than the pressure in the normal detonation wave. In this case the velocity of overcompressed wave was equal to 1.04 times the vel of normal deton wave, but...

Such data are necessary for calculation of parameters in the classification of coal by rank dry, mineral-matter-free volatile matter (or fixed carbon) as well as moist, mineral-matter-free gross calorific value. For volatile matter and fixed-carbon data, it is also necessary to assume that 50% by weight of the sulfur is volatilized in the volatile matter test and therefore should not be included as part of the organic volatile matter (nor should the loss from clays and carbonate minerals) ...

The basis for the simple expression of Equation 1 is found in many articles on quantitative analytical-electron-microscopy (11). The original application to light matrices, though, was made by Hall for biologically important materials (12.13). Understanding of details of calculation of parameters making up the constant A can be obtained from his work. 

A scratch pad can be very useful for a spread-sheet user. A scratch pad is an area (e.g., columns to the right of the main spread sheet) set aside for doing side calculations of parameters or constants for the main spread sheet, writing comments, locating macros, and other uses. A scratch pad would be useful in this example if the user needed mass balances for a particular product flow rate rather than a specified feed rate as just illustrated. The problem has been solved for a carbon dioxide feed rate of 100 mol/h as shown above, but suppose it is desired to know the feed rate required to produce 880 mol/h of methanol product. The problem might intentionally be solved first for a specified feed rate, because it is often more convenient to write the mass-balance equations for known process feed rates rather than known product rates. 

It should be mentioned that, in the calculation of parameter s represents the number of spheres circumscribed to the experimental centre plan, y is recognized as the radius of each i circumscribed sphere (see relation (5.115)) and n is the... 

Two kinetic (CMS-Kl, CMS-K2) and one equilibrium (CMS-R) carbon molecular sieves, used originally for separation of gaseous mixtures, were investigated. The adsorption Nj isotherms at 77 K, in static conditions where obtained. In the case of the two first sieves the adsorption was so low that the calculation of parameters characterizing the texture was impossible. The volume of nitrogen adsorbed on the sieve CMS-R is remarkable From obtained results parameters characterizing micropore structure according to Dubinin -Radushkevich equation and Horvath - Kawazoe method were determined. 

Several applications of univariate statistical analysis for data evaluation in Py-MS are known [73]. One such application is the evaluation of reproducibility of a replicate of an analysis for the peak intensity at a given m/z value. If a series of measurements are made on identical specimens, this will provide a sample xi, X2...Xn. This sample will allow the calculation of parameters such as the mean m and the standard deviation s. By comparing the value s for different m/z values it is possible to select those m/z that are more reproducible (smaller s).

In much of statistics, the notion of a population is stressed and the subject is sometimes even defined as the science of making statements about populations using samples. However, the notion of a population can be extremely elusive. In survey work, for example, we often have a definite population of units in mind and a sample is taken from this population, sometimes according to some well-specified probabilistic rule. If this rule is used as the basis for calculation of parameter estimates and their standard errors, then this is referred to as design-based inference (Lehtonen and Pahkinen, 2004). Because there is a form of design-based inference which applies to experiments also, we shall refer to it when used for samples as sampling-based inference. 

Shape Selectivity Molecular recognition of the solute by the stationary phase with respect to its geometrical dimension is called shape selectivity. For this test, one can employ aromatic components with identical hydrophobicity that differ only in their three-dimensional shape. The chromatographic selectivity of o-terphe-nyl/triphenylene or tetra-benzonaphthalene/benzo[a]pyrene are commonly used and show dependencies on several features of the phase, for example, pore structure, ligand type, and density. Figure 3.6 shows a chromatogram of a test mixture of uracil (to marker), n-butylbenzene, and w-pentylbenzene (to assess hydrophobic properties and efficiency), and o-terphenyl and triphenylene (to assess shape selectivity). The test mixture was chosen to provide a short analysis time and to facilitate calculation of parameters from baseline-separated peaks. 

In a more complicated way similar reasons can be related to masses of an electron and nucleon. The complicity is because we rather expect that a, if calculable, is calculable in a kind of one-step action (with further renormalization), while for masses we need to go step by step. For instance, for the electron we should first understand the calculability of parameters of the Higgs sector.

Measurements of chlorophyll a fluorescence with a modulation fluorometer (Walz, Effeltrich, FRG) and pigment analyses with TLC are described elsewhere (7).

Here co is frequency of oscillating electron in the first atom, Kq is polarizability of the second atom, r is distance between the two. This result is in qualitative agreement with a quantum-mechanical theory developed by London. For calculation of parameter A in (6.71) Maier and Saupe used this basic formula, but in addition they took the anisotropy of molecular polarizability Act into account. It is Aa that determines the stability of the nematic phase. 

This formula for the calculation of parameter q can be generalized on the various sets of reference w-alkanes.
