The —> operator used on a collection evaluates an attribute on the collection itself rather than on each of its elements. Several operations on collections—select, forAII—take a block argument representing a single argument function evaluated on each element of the collection. Some operators, such as sum and average, are specifically defined to apply to collections of numbers. [Pg.90]

Consider again the general formulation of cooperative uniform kinetics embodied in Eq. (102). Suppose that the value of F[ ] must be nonnegative and must be zero only if the argument function c(z,r) is zero. Then Eq. (102) describes irreversible kinetics, since the rate of consumption —cjix,t) becomes zero only when c x,f) = 0. However, Eq. (102) can also describe reversible kinetics. Let c (x) be the equilibrium concentration distribution that will eventually be attained from the initial distribution c( c,0), and let F[c (z)] = 0, so that the (reversible) equilibrium condition is satisfied at some nonzero c (jc). Equation (102), however, can only describe a special form of approach to equilibrium. In fact, suppose that F[c(z,0)] is positive (or negative). Equation (102) now implies that the concentration of all reactants decreases (or increases) until c(x,t) becomes equal to c (jc). This implies two things ... [Pg.40]

The whole problem has thus been reduced to the solution of Eq. (134), which is a functional equation for the single scalar W. It is, however, a nasty functional equation, not so much for the possible nonlinearity of the functional F[ ] itself, but because the argument function is nonlinear in the unknown W. The warped time technique is again useful, but, contrary to what happens in the single-component case, the solution for the CSTR is more difficult than the one for the plug flow reactor or batch reactor. [Pg.50]

Section 2.3 discussed how context is (somewhat vaguely) defined in authoritative guides to GSN. Section 3.3 showed that context elements in assured safety arguments function as claims of acceptable instantiation and fitness for role. These definitions are mutually exclusive. Clarification and identification of reference material cannot introduce new claims. Introduction of claims contradicts the prohibition on using context elements to refer to information which is intended to support the validity of a claim [3, Sect. 2.6.2.Ij. [Pg.148]

A conceptually more accessible way to a stochastic process is the involvement of an abstract argument representing a sample point, and thus a stochastic process is denoted by X w, t), where m denotes a sample point in the sample space. By this it is very clear that X is a multi-argument function of m and f. Because X is a function of m, it is stochastic in nature. Simultaneously because X is also a function of f, it is a process. Thus X w, t) is a stochastic process. Eor practical applications the dehciency of this description is that m is a mathematically abstract point in the sample space and its relation to the physical entities is still not exposed. A further step could be made by introducing the embedded basic random variables in the physical problems under consideration, denoted by 0(c7) = [0i(c7), 2(m), , 0j(u7)] for convenience, and thus a stochastic process could be represented by X(tu, t) = g(0(tu), f), where g(-) is an explicit function of (m) and t. The form of g( ) could be determined by the embedded physical mechanism or by mathematical decomposition if phenomenological statistical models are involved, as shown in the following subsections. [Pg.1989]

If the Jacobian matrix can be compnted anal5dically, we use Options = optimset(Options, Jacobian, on ) and return the Jacobian as a second argument, function [f, Jac] = funjiame(x, P1, P2,...) ... [Pg.98]

Equation (7-8). However, for liquid-liquid equilibria, the equilibrium ratios are strong functions of both phase compositions. The system is thus far more difficult to solve than the superficially similar system of equations for the isothermal vapor-liquid flash. In fact, some of the arguments leading to the selection of the Rachford-Rice form for Equation (7-17) do not apply strictly in the case of two liquid phases. Nevertheless, this form does avoid spurious roots at a = 0 or 1 and has been shown, by extensive experience, to be marltedly superior to alternatives. [Pg.115]

The MOD function returns the remainder when the first argument is divided by t second (for example, MOD(14,5) equals 4). If the constants are chosen carefully, the line congruential method generates all possible integers between 0 and m — 1, and the peril (i.e. the number of iterations before the sequence starts to repeat itself) will be equal... [Pg.435]

For the orbital parts of the electronic wave functions of two electronic states the selection rules depend entirely on symmetry properties. [In fact, the electronic selection rules can also be obtained, from symmetry arguments only, for diatomic molecules and atoms, using the (or and Kf point groups, respectively but it is more... [Pg.275]
