The solution surfaces cannot intersect. If they did, states located at the points of intersection would have multiple values of entropy, and this would violate a fundamental property of state functions. Thus, the surfaces can be expected to be ordered monotonically, either systematically increasing (or decreasing) as one proceeds in a given direction from surface to surface. For our purposes, let us assume Si >S2>S3 in Figure 2.12. [Pg.79]

It must be realized that the basic reason for bifurcation is that the function F is multiple-valued and therefore non-linear. Other sources of non-linearity, like auto-catalysis have been explored systematically and have proven to be the starting point of geochemical catastrophes (e.g., Ortoleva, 1994). [Pg.364]

Empirical multiple linear regression models were developed to describe the foam capacity and stability data of Figures 2 and 4 as a function of pH and suspension concentration (Tables III and IV). These statistical analyses and foaming procedures were modeled after data published earlier (23, 24, 29, 30, 31). The multiple values of 0.9601 and 0.9563 for foam capacity and stability, respectively, were very high, indicating that approximately 96% of the variability contributing to both of these functional properties of foam was accounted for by the seven variables used in the equation. [Pg.158]

PMs, individuals who have no functional alleles (—/—), (3) intermediate metabolizers (IMs), individuals who have two partially functional alleles or one partially functional and one nonfunctional allele ( / or /—), and (4) UMs, individuals who, through gene duplication, have multiple copies of the functional gene [(+/+) ]. This traditional classification scheme has been revised recently on the basis of an activity score, which assigns to each allelic variant a functional activity value from one (for the wild-type or 1 allele) to zero (for any completely nonfunctional allele), as reviewed by Zineh et al. (18). The basis of the activity score, as it applies to CYP2D6, is illustrated in Table 1. [Pg.235]

For exothermic reactions (fi > 0) a sufficient temperature rise due to heat transfer limitations may increase the rate constant Ay. and this increase may offset the diffusion limitation on the rate of reaction (the decrease in reactant concentrations CA), leading to a larger internal rate of reaction than at surface conditions CAs. This, eventually, leads to 17 > 1. As the heat of reaction is a strong function of temperature, Eq. (9.24) may lead to multiple solutions and three possible values of the effectiveness factor may be obtained for very large values of /I and a narrow range of catalytic reactions, (3 is usually <0.1, and therefore, we do not observe multiple values of the effectiveness factor. The criterion... [Pg.458]

Fromm and Hill s paper, while a sophistieated and almost miraculous application of complex variable theory, produced a formula that exhibited two problems from a practical viewpoint. It contained the dilogarithm function, Li2, and squares of logarithmic functions, in combinations that were multiple-valued with respect to both their real and imaginary parts, and no simple recipe was provided to indicate which branches of these functions should be used. Fromm and Hill s provisional solution was to start from a point in the parameter space where the proper branch was known from asymptotic considerations, and then move in steps to the required parameter values. This procedure was referred to as branch tracking . [Pg.143]

The boundary condition relevant to motion in a circle is different from that required for a particle in a box, where the wavefunction had to go to zero at the ends of the box. For circular motion the wavefunction has to match up with itself after one complete revolution of the circle. This requires the circumference of the circle to be equal to a whole number of wavelengths. The situation where five wavelengths fit into the circle is illustrated for the sine function in Figure 5.3a. The plot for the cosine function would be similar, but rotated through 90 . If this condition is not met the waves will not coincide with one another after one complete revolution, and multiple values of will be obtained for any particular point on the circle, as shown in Figure 5.3b. As we saw in Section 1.4.5,... [Pg.71]

To use a GA for Multiobjective Optimization (MO) entails comparing two solutions with respect to the multiple objectives considered [Carlos et al., 2007], [Toshinsky et al., 2000]. In the case of a singleobjective, the comparison is trivial a vector solution X is better than another one, say y, if the corresponding objective function (fitness) value f(x) is greater than f(y).A multiobjective optimization problem, instead, deals with Nf objective functions i = 1,2,..., Nf this requires that two solutions x and y are compared in terms of dominance of one solution over the other with respect to atUV)- objectives [Sawaragi et al., 1985]. The multiobjective optimality search process, converges on a Pareto-optimal set of nondominated solutions, which provides a spectrum of possible choices for the decision-maker to a posteriori identify his or her preferred solution. [Pg.1494]
