Maximum relative

Such a stationary value of V can be a relative maximum, a relative minimum, a neutral point, or an inflection point as shown in Figure B-1. There, Equation (B.1) is satisfied at points 1, 2, 3, 4, and 5. By inspection, the function V(x) has a relative minimum at points 1 and 4, a relative maximum at point 3, and an inflection point at point 2. Also shown in Figure B-1 at position 5 is a succession of neutral points for which all derivatives of V(x) vanish. A simple physical example of such stationary values is a bead on a wire shaped as in Figure B-1. That is, a minimum of V(x) (the total potential energy of the bead) corresponds to stable equilibrium, a maximum or inflection point to unstable equilibrium, and a neutral point to neutral equilibrium. [Pg.479]

The character of AV will determine the type of stationary value at x = Xi. Specifically, the dominant term in the Taylor series for AV must be examined in order to determine whether AV is always positive (a relative minimum), always negative (a relative maximum), sometimes negative and sometimes positive (an inflection point), or always zero (a neutral point). For AV to be positive, the leading term in the Taylor series, Equation (B.4), which is by inspection the largest term because h is a very small number, must be positive, i.e.. [Pg.480]

If the first nonzero derivative evaluated at x = x., is even and less than zero, then V(x.,) is a relative maximum. [Pg.481]

The absolute maximum (or minimum) of f(x) at x = a exists if f(x) < f(a) (or f(x) > f(a)) for all x in the domain of the function and need not be a relative maximum or minimum. If a function is defined and continuous on a closed interval, it tvill altvays have an absolute minimum and an absolute maximum, and they tvill be found either at a relative minimum and a relative maximum or at the endpoints of the interval. [Pg.38]

Four categories of effectors (additives to the Solka Floe fermentations) can be classified by comparing relative maximum emgmie concentration and relative time required to reach the maximum FPA, to the chemical structures of these supplementing compounds. [Pg.341]

This result is obtainable directly from electrostatics, and the general solution of the LPBE (Equation 2) determines only the distance at which dq has a maximum value, i.e., R = (a + k 1). The distance R gives only the relative maximum, the absolute maximum being arbitrarily specified by the angular coordinates 0i, <. It will be evident that there are only a few reasonable choices for n, 0i, and <, depending on the valency of the central ion. [Pg.205]

This transition-state-like point is called a bond critical point. All points at which the first derivatives are zero (caveat above) are critical points, so the nuclei are also critical points. Analogously to the energy/geometry Hessian of a potential energy surface, an electron density function critical point (a relative maximum or minimum or saddle point) can be characterized in terms of its second derivatives by diagonalizing the p/q Hessian([Pg.356]

In each individual step of a reaction, the state of highest energy between reactants and products. The transition state is a relative maximum (high point) on the reaction-energy diagram, (p. 233) A dihalide with the halogens on adjacent carbon atoms, (p. 220)... [Pg.279]

As noted previously by Senich et al. (8), the usefulness of the DSA technique in following the cure of epoxy curing systems stems from the fact that a relative maximum Is produced in the composite loss tangent when the viscosity of the resin reaches a predetermined value. In a previous study (23) which considered a series of polystyrenes of varying molecular weights characterized... [Pg.226]

An interesting investigation on the influence of multiplicative non-white noise in an analog circuit simulating a Langevin equation of a Brownian particle in a double-well potential has been carried out by Sancho et al. This device allowed them to study the stationary properties as a function of the noise correlation time. Theory in a white-noise limit cannot provide a satisfactory explanation for experimental results such as a relative maximum of the probability distribution and the maximum position in the stationary distribution for noises of weak intensity. [Pg.452]

It can be seen that the relative maxima are completely dependent on efficacy, receptor density, and the efficiency of stimulus-response coupling (x = [R]/KE see Chapter 3). However, the relationship is not a direct one. Figure 5.22 shows the relative maximum response to two agonists in a... [Pg.97]

The deposition pattern in Figure 4 is almost identical to the concentrations. The one exception to the simple correlation between concentration and deposition is in southeast Louisiana. The heavy precipitation in that area explains the relative maximum in deposition extending from the Delta region northward into central Arkansas. [Pg.34]

Two additional phenomena contribute to the thermal degradation mechanism and can determine the formation of the relative maximum and minimum in the characteristic surface of the gaseous MWD as shown in Fig. 1. In the backbiting process, the end of polymer chain can also react to form gaseous products with a non-random distribution through a sequence of isomerization and /1-scission reactions. Finally, monomer units can also be released by an unzipping process through /1-scission of the terminal radicals. [Pg.140]

Crutzen (1974) and Crutzen et al. (1978) carried out some of the first detailed chemical models of chlorine-catalyzed ozone depletion, building upon the studies of Stolarski and Cicerone (1974), Molina and Rowland (1974) and Rowland and Molina (1975) and including the general chemical understanding outlined above. Crutzen (1974) predicted a relative maximum in CIO near 40 km, which was broadly confirmed a... [Pg.456]

For a direct comparison between the two irradiation wavelengths, the relative maximum peak intensities of different fragments are compared. In Fig. 47 the response of the most intense mass (i.e., 28 amu from N2) at the two different irradiation wavelengths is shown. The data taken after irradiation at 308 nm exhibit a linear increase of the signal intensities at low flu-ences (<40 mj cm 2), as shown in the insert in Fig. 47. At higher fluences a fast increase is observed. This is an indication that at fluences above... [Pg.143]
