The values in Table VI were obtained in the following way. Values for C, Si, Ge, and Sn are the same as in Table III, for the tetrahedral configuration is the normal one for these atoms. Radii for F, Cl, Br, and I were taken as one-half the band-spectral values for the equilibrium separation in the diatomic molecules of these substances. Inasmuch as these radii for F and Cl are numerically the same as the tetrahedral radii for these atoms, the values for N, 0, P, and S given in Table III were also accepted as normal-valence radii for these atoms. The differences of 0.03 A between the normal-valence radius and the tetrahedral radius for Br and...

Here K is the kernel matrix determining the linear operator in the inversion, A is the resulting spectrum vector and Es is the input data. The matrix element of K for Laplace inversion is Ky = exp(—ti/xy) where t [ and t,- are the lists of the values for tD and decay time constant t, respectively. The inclusion of the last term a 11 A 2 penalizes extremely large spectral values and thus suppresses undesired spikes in the DDIF spectrum. 

Therefore, if A represents the spectrum, the various a represent convolution coefficients and Var(A) represents a noise source that gives a constant noise level to the spectral values, then equation 57-36 gives the noise variance expected to be found on the computed resultant value, whether that is a smoothed spectral value, or any order derivative computed from a Savitzky-Golay convolution. For a more realistic computation, an interested (and energetic) reader may wish to compute and use the actual noise that will occur on a spectrum, from the information determined in the previous chapters [6-7] instead of using a constant-noise model. But for our current purposes we will retain the constant-noise model then equation 57-36 can be simplified slightly ... 

Figure 3.8 Effects of tf-amphetamine on the wake EEG Mean EEG spectral values for six healthy male subjects who took placebo. 5 mg and 10 mg of d-amphetamine on separate occasions in a balanced crossover trial are shown Whereas the EEG trace 2 h after placebo (upper third) shows a rapid decline in alpha waves and an increase in theta waves (see arrows pointing to the alpha decrease and the theta increaee), the corresponding changes occurred later after 5 mg (middle third) andlOmg (tower third) d-amphetamine The decay of alpha and increaee of theta activities occurred after 2 mm on placebo, but only after 7 min on 5 mg d-amphetanine and after 12 mn on 10 mg of d-amphetamine, thus reflecting a vigilance-stabilizing effect of tf-aiphetamine (Matejcek, 1979, with permission)...

Noiseless Coding. Huffman coding is applied for the quantized spectrum, the differential scalefactors, and directional information. A total of 12 static Huffman codebooks are employed to code pairs or quadruples of spectral values. 

From spectrophotometric studies30, 119 122 U(TTA)4 was shown to form 1 1 adducts with neutral donors of widely differing basicities. The absorption spectrum of U(TTA)4 in benzene in presence of different amounts of TOPO is shown in Fig. 3, the isosbestic points of which suggest the formation of only one adduct in the system. The adduct formation constants are summarized in Table 12. The results of a recent nmr study122 are also included in this table. The difference between the nmr and the absorption spectral values remains to be explained. It may be connected with the diluent acetone which itself is a neutral donor120 of relatively poor basicity.

All pixel vectors in a test image are first normalized by a constant, which is a maximum value obtained from all the spectral components of the spectral vectors in the corresponding test image, so that the entries of the normalized pixel vectors fit into the interval of spectral values between zero and one. The rescaling of pixel vectors was mainly performed to effectively utilize the dynamic range of Gaussian RBF kernel. 

Figure 12 shows spectral for Crater Lake calculated at 10 nm intervals from underwater spectral irradiance data collected at nearly the same time as the data in Figure 11, in this case using a LI-COR spectroradiometer (model LI-1800UW, 8 nm bandwidth).

Data arrays (one-way data) consist of spectral values taken at a given time point or electrophoretic responses at a given wavelength over time. One-way data can be used for sample characterization, classification, and quantification with multivariate calibration methods (e.g., principal component analysis and partial least square regression).
