INDEX functions used

In the foregoing the description of microresonators was limited to the index guiding type. Resonators with the same functionality can be implemented in PBG structures5. In these cases, with the high index contrast used, the cavity volume is even more reduced resulting in FSRs of 10 - 100 nm. [Pg.285]

A new approach for computerized Inherent Safety Index is also presented. The index is used for the synthesis of inherently safer processes by using the index as a fitness function in the optimization of the process structure by an algorithm that is based on the combination of an genetic algorithm and case-based reasoning. Two case studies on the synthesis of inherently safer processes are given in the end. [Pg.6]

Slater-type orbitals were introduced in Section 5.2 (Eq. (5.2)) as the basis functions used in extended Huckel theory. As noted in that discussion, STOs have a number of attractive features primarily associated with the degree to which they closely resemble hydrogenic atomic orbitals. In ab initio HF theory, however, they suffer from a fairly significant limitation. There is no analytical solution available for the general four-index integral (Eq. [Pg.167]

However, an Italian investigation of sexual and erectile function, using questionnaires directed to 186 patients treated at various centers with finasteride 1 mg/day for 4-6 months has challenged the accepted wisdom the authors concluded that (as judged by the five-item International Index of Erectile Function) there was no adverse effect on erection after this period of time (65). [Pg.154]

The determination of refractive index is useful in assisting the characterisation of a pure liquid, particularly in the case of compounds which do not possess functional groups suitable for conversion into solid derivatives. The refractive index is conveniently determined with an Abbe refractometer (Section 2.37). An additional characteristic is provided by the density of the liquid, which is determined with the aid of a pycnometer. [Pg.1198]

A convolution of these values with the cochlear spreading function follows. Due to the non-normalized nature of the spreading function, the convolved versions of eb and cb should be renormalized. The convolved unpredictability, ch, is mapped to the tonality index, tb, using a log transform just as the unpredictability was mapped to the tonality index, c(t, CO), from equation (2.12). [Pg.47]

In the field of computer music, it is customary to use simple piecewise linear functions for functions other than signals at the audio sampling rate, e.g., for amplitude envelopes, FM-index functions, and so on [Roads and Strawn, 1985, Roads, 1989]. Along these lines, good initial results were obtained using the simplified qualitatively chosen table... [Pg.531]

It has been stated that, when specific hydrogen-bonding effects are excluded, and differential polarizability effects are similar or minimized, the solvent polarity scales derived from UV/Vis absorption spectra Z,S,Ei 2Qi),n, Xk E- ), fluorescence speetra Py), infrared spectra (G), ESR spectra [a( " N)], NMR spectra (P), and NMR spectra AN) are linear with each other for a set of select solvents, i.e. non-HBD aliphatic solvents with a single dominant group dipole [263]. This result can be taken as confirmation that all these solvent scales do in fact describe intrinsic solvent properties and that they are to a great extent independent of the experimental methods and indicators used in their measurement [263], That these empirical solvent parameters correlate linearly with solvent dipole moments and functions of the relative permittivities (either alone or in combination with refractive index functions) indicates that they are a measure of the solvent dipolarity and polarizability, provided that specific solute/ solvent interactions are excluded. [Pg.450]

Here a and b stand for orbital basis functions and c denotes Gaussian functions used in the fitting of the electron density or the exchange-correlation potential. Most of the time is spent in the computation of I. We can rewrite the original Obara and Saika formula (15) in a form suitable for computation of three-index integrals ... [Pg.230]

The detector response index has been featured as a means of defining linearity, but it can also be used to take into account any non-linearity that is present and appropriately modify the peak height or peak area calculations and thus improve quantitative accuracy. An example of two peaks constructed from Gaussian functions using response factors of 0.95 and 1.05 are shown in figure 5. Such values were considered to be outside those which would be acceptable for a detector to be defined as linear. [Pg.480]

You can select individual values in an array by using the INDEX function, but this is a "read-only" option. If you need to be able to change individual values in an array, you should enter the values in a range of worksheet cells, rather than as an array. [Pg.94]

Sorting a multi-column list using the LARGE function is only slightly more complicated, provided there are no duplicate entries in the column on which the sort is performed. You can use the MATCH and INDEX functions to return the values in the same row as the "sortkey" value. Figure 4-12 illustrates a portion of a list of polymer research samples and some of their physical properties. The columns in this raw data table were assigned the names SampleNumber, FormulationType, etc. [Pg.105]

The symmetry properties of the permutation operator P(x x2x3) need not be separately considered in light of the relation between P(xx x2x3) and P(x x2 x3) [cf. Eq. (114)]. The remaining permutation operator used in Table I but thus far not discussed in this section is P(jci jc2 x3), defined in Eq. (102). We now show that P(xt x2 x3) is the composite of two single-index set permutation operators already examined. In addition to/ and g, let A (jc,) be an arbitrary single-index function, which may depend parametrically on other variables then... [Pg.266]

Direct Cl methods often require an index vector which points to a list of all allowed excitations from a given iV-electron basis function. Using alpha and beta strings, the index vector need not be the length of the Cl vector—its size is dictated by the number of alpha or beta strings, which (for a full Cl) is approximately the square root of the number of determinants. This results from the fact that in determinant-based Cl, electrons in alpha spin-orbitals can be excited only to other alpha spin-orbitals, and electrons in beta spin-orbitals can be excited only to other beta spin-orbitals (because of the restriction to a single value of Ms). [Pg.193]
