Sample Order

A first-order sampled-data system is shown in Figure 7.10. 

To obtain the z-transform of a first-order sampled data system in cascade with a zero-order hold (zoh), as shown in Figure 7.10. 

Figure 1. Three different distributions of Rh (dark gray) and Pd (light gray) atoms in equiatomic fee Rh-Pd alloy. The ordered sample (LIq strueture, top), the random sample (middle), and the segregated sample (bottom) were construeted on the fee underlying lattiee for the 144 atomie supereell.

Figure 2. Total energies of ordered (LIq structure, squares), random (circles) and segregated (triangles) fee RhsoPdso alloys as a function of the number of neighboring shells included in the local interaction zone. Values obtained by the LSGF-CPA method are shown by filled symbols and full lines. The energies obtained by the reference calculations are shown by a dashed line (LMTO, ordered sample), a dotted line (LMTO-CPA, random sample), and a dot-dashed line (interface Green s function technique, segregated sample).

Among the Ti-SBA-15 samples, the activity decreased in the order, sample 1 > sample 2 > sample 3. The intensity of the broad band in the 200-350 nm DRUV spectra of these samples also follows the same order (Fig. 36) and is a rough measure of the dispersion of Ti in the sample. The higher catalytic activity of Ti-MMM was ascribed to its greater surface Ti concentration. 

The essence of a QQ-plot is to plot the ordered sample values against some representative values from a presumed null standard distribution F(°). These representative values are the quantiles of the distribution function F(°) corresponding to a cumulative probability pc, [e.g., (t — 0.5)/M] and are determined by the expected values of the standard order statistics from the reference distribution. Thus, if the configuration of the QQ-plot in Eq. (11.30) is fairly linear, it indicates that the observations ( y(/), i = 1,..., M) have the same distribution function as F(°), even in the tails. 

Lot Acceptance Tests. Unless otherwise specified in the contract or order, samples selected from each inspection lot shall be subjected to all the requirements and tests of this specification. Failure of the HBX compositions to meet any of the requirements or tests of this specification shall be considered cause for rejection of the lot... 

By flipping the sample between the evolution and detection periods (so that the axial symmetry is broken), the correlation spectrum of two sample orientations can be established, as shown in the early single-crystal experiment by Carter et al 254,255 "phis technique was employed by Henrichs256 to propose a unique type of correlation spectrum in solid-state NMR by which the orientation correlation is established and the orientation distribution of ordered samples can be determined.
