Order roots

To find the C numerator in Eq. (9.36) a second derivative with respect to s would have to be taken. Generalizing to the mth term A of an th-order root at pi. [Pg.311]

There is a quantitative relationship between the location of roots in the s plane and the damping coefficient. Assume we have a second-order system or, if it is of higher order, assume it is dominated by the second-order roots closest to the imaginary axis. As shown in Fig. 10,5 the two roots are Si and and they are, of course, complex conjugates. From Eq. 6.68) the two roots are... [Pg.352]

Figure 10.St>,c gives tbe root locus plots for two values of the reset lime constant z,. With Zj = 4.5 in Fig. lO.gt), the ultimate gain is reduced to 5i (compared to the ultimate gain of 64 for a proportional only controller), and the gain that gives a closedloop damping coelTicient of 0.316 is 15. There is a first-order root on the real axis near the origin. Figure 10.St>,c gives tbe root locus plots for two values of the reset lime constant z,.

The roots of the zero -order equation ares (0) = ico(q) and so<0) = 0. The roots of the first-order equation corresponding to these zero order roots are 5 (1) = —j [(7 — 1)Dt + Dv]q2 and j0(1) = —Drq2- Adding each zero order root to its corresponding first-order root gives the three roots of the dispersion equation which are correct to first order in Dvq2 and Drq2- These are... [Pg.242]

In addition to the inter- and intraspecies variations in Cd concentrations in plants, marked differences also occur in the accumulations of Cd between various plant parts, in the order, roots > stems and leaves > > grain and tubers (Table 12). High Cd concentrations in root tissues have been reported in a number of studies of a variety of plant species (Mitchell et al., 1978 Kraffczyck et al., 1984 Horijn and Van Beusichem, 1993 Cieshnski et al., 1996). However, root concentrations... [Pg.227]

Similarly to the result obtained for QRs, these unitary DSs are just the spatial transformations dictated by the symmetry of the nanotube potential and compensated by the appropriate translation in time. It is interesting to examine the quantum numbers associated with the DSs Rjv and Poo- Note that the Floquet states 0 (r, t) are eigenstates of P and as well. Recall, that for QRs we have = I and, therefore, the eigenvalues of Pjv are the Mh order roots of - 1. The situation is more intricate for nanotubes in circularly polarized fields, where we find P P = I. Owing to the foim of the interaction term, equation (28), and the periodicity embedded in P, it is natural to transform from z and t to another set of orthogonal coordinates o)t — Icqz and cjt + koz)/2. Afterwards, it is possible to rewrite a Floquet state as... [Pg.403]

Distribution of metals in different parts of the plants is not uniform. If foliar versus root intake is negligible (less polluted localities), the concentrations of these elements generally decrease in the order roots > leaves > stems > fruits > seeds. These factors should be taken into account when assessing the levels of toxic elements in plants, because only certain parts of the same plant are consumed by herbivores, and only certain parts of cultivated plants are processed for food or feed use. It is in this way that the toxic elements present in the plants enter the food chain. [Pg.458]

Jo - Bessel function of first kind, zero order, - root of the equation Jg( x) = 0. [Pg.572]

According to the HUM interleaving theorem, the ordered roots for order n interleave those for order m + 1, namely. [Pg.254]

The scanner has been constructed in modules which, for future applications, makes it easy to increase the length of the scanner for inspection of larger blades, by adding further modules to the system. In co-operation with LM Glasfiber and RIS0 it was decided to construct the first scatmer for inspection of blades with a length of max. 21m. In order to be able to scan primarily the bonded areas from the root to the tip of the rotor blade, a so-called X-unit module was constructed. The movement from the root to the tip of the blade was controlled by the P-scan system. [Pg.982]

A hierarchical system is the simplest type ofdatabase system. In this form, the var-iou.s data typc.s also called entities (sec figure 5-,3) arc as.signcd. systematically to various levels (Figure 5-5). The hierarchical system is represented as an upside-down tree with one root segment and ordered nodes. Each parent object can have one or more children (objects) but each child has only one parent. If an object should have more than one parent, this entity has to be placed a second time at another place in the database system. [Pg.232]

The anticatalytic effect of nitrous acid in nitration The effect of nitrous acid was first observed for zeroth-order nitrations in nitromethane ( 3.2). The effect was a true negative catalysis the kinetic order was not affected, and nitrous acid was neither consumed nor produced by the nitration. The same was true for nitration in acetic acid. In the zeroth-order nitrations the rate depended on the reciprocal of the square root of the concentration of nitrous acid =... [Pg.55]

The concentration of alkaloids, as well as the specific area of occurrence or localization within the plant or animal, can vary enormously. Thus the amount of nicotine [54-11-5] (21), C2QH24N2, apparentiy synthesized ia the roots of various species of JSHcotiana and subsequentiy translocated to the leaves varies with soil conditions, moisture, extent of cultivation, season of harvest, etc and may be as high as 8% of the dry leaf, whereas the amount of morphine (2, R = H) ia cerebrospiaal duid is of the order of 2 to 339 fmol/mL (23). [Pg.533]
