Functional notation

An Example of Functional Notation Suppose that a storage warehouse of 16,000 fF is required. The construction costs per square foot are 10, 3, and 2 for walls, roof, and floor respectively. What are the minimum cost dimensions Thus, with h = height, x = width, and y = length, the respective costs are... 

The abstract and re-refine technique helps ensure that overall goals of the organization are still met insofar as they can be expressed in a functional notation. 

Note that this is exactly the same characteristic equation that we found using the transfer function notation [sec Eq. (15.68)]. 

The Bond function describes a central atom of reference and the atoms bonded to it. B211 states that there is a central atom of reference bonded to one atom by a double bond (2) and to two other atoms by single bonds (1). The order of the Bond function arguments corresponds to this Bond function notation. These arguments are not simple atomic symbols, but Atom functions that can relate considerable information about the atom. In this Bond function, Atom(C,1,0,0,0) is the central atom. The next three arguments are atoms that are bonded to this central atom the first, Atom(0,3,0,0,0) by a double bond the next two, Atom(C,2,0,0,0) and Atom(H,4,0,0,0), by single bonds. 

The functional notation for the Gibbs free energy (g(T, X)) shows that it is only a function of temperature and mole fractions at the given location. No pressure term is shown in the function for the Gibbs free energy, since pressure is assumed constant for this analysis. The energy equation now becomes ... 

Equation 3.2.6 gives the concentration of water vapor in the inlet air as function of tjw, yiw, and Ahyw, where the subscript, w, means wet bulb. The equations are in functional notation to indicate that these data may be available in tables, graphs or equations. The wet-bulb temperature, tiw, will be discussed later. Equation 3.2.7 expresses the mole fraction of water vapor in the exit air in terms of the vapor pressure at saturation. The air leaving the tower is assumed to be 90% saturated, a value recommended by Walas [12]. 

A periodic function is a function whose values repeat at regular intervals. Given an interval of length t, and a function f, if the value of the function at x + t is equal to the value of the function at x then f is a periodic function. In standard function notation this is written f(x... 

The more detailed algorithmic notation is used for the original definitions, and the functional notation is derived from it. 

Functional notation. The secret value sk temp is exactly the secret information that the signer s entity stores at the end of initialization. However, more secret random bits may be generated later. (Formally, they are read from a random tape.) It is sometimes useful to have a notation for all the secret information that a signer s entity ever uses. Hence let be a sufficiently long string of random bits, and let... 

Definition 7.3 (Functional notation). The names of the algorithms in Definitions 7.1 and 7.2 can also be used for the (probabilistic or deterministic) functions realized by these algorithms. However, this notation is only used with test and verify. For the three other components, the following probabilistic functions are defined ... 

Note that the functional notation does not treat the case i > N. The following formal security definitions implicitly take Property c) from Definition 7.1 for granted, i.e., they do not treat what a signer s entity might do in authentications after the message bound has been reached, because it does not do anything. 

The probability spaces defined by protocol executions with given parameters are written g(par), Geif B(par, i), and Gen g Qipar, i), respectively, and the functional notation is adapted accordingly. 

The definition of effectiveness of authentication deals with arbitrary signatures in the sequence of signatures hence the functional notation is used. 

As this definition deals with unrestricted attackers, functional notation is used. First, some notation about forgeries is introduced. 

Let/ = mj, j, sj, mk , s )). Moreover, as the security definition is in functional notation, whereas Construction 10.13 is algorithmic, let the current value skjemp be redefined in terms of the history, i.e., as the result of applying sign to the messages from m, given the original temporary secret key and the random string from sk. ... 

Definition 11.19 (Rudimentary standard information-theoretically secure signature schemes). The components of a rudimentary standard information-theoretically secure signature scheme (in functional notation) for a nonempty message space Me 0, and a non-empty set Messagejbounds c N u oo are a triple Gen, sign, test) where... 

SXgj is the part of SK that is actually used for signing m. In the given functional notation, the value of SK can be defined as the shortest prefix of sk that uniquely determines the correct signatures on all the messages from m. Hence one can write... 

To get an idea about the spectral and directional complexity of the rigorous modeling of radiant heat transfer the variables that must be specified for the radiative properties are introduced. A functional notation is used to give explicitly the variables upon which a quantity depends. The most fundamental variables includes dependencies on wavelength, direction, and surface temperature. A total quantity does not have a spectral dependency. A hemispherical spectral variable does not have a directional dependency. A hemispherical total quantity has only a temperature dependency. 

In Green s function notation this would be written...

Consider a solution where only O is present initially at a concentration Cq, semi-infinite linear diffusion conditions prevail, and a constant cathodic current i is applied for a time t (where t with ti being the forward transition time). At ti the current is reversed, that is, the direction of the current is changed from cathodic to anodic, so that R formed during the forward step is oxidized to O, and the time T2 (measured from ti) at which Cr at the electrode surface drops to zero is noted. At T2, the reverse transition time, the potential shows a rapid change toward positive values. We desire an expression for T2- This is most easily accomplished using the zero shift theorem of Section A. 1.7. Since for 0 < / < i(t) = i, and for ti < t t + T2, i(t) = —i, the expression for the current, using step function notation, is... 

With these definitions, and the functional notation for the electron repulsion matrices introduced in Appendix 3.C, the energy function becomes... 

We will deal only with real vibrational and orbital wave functions in our analysis so that the complex function notation need not be used.
