Signals, chemical input

FIGURE 5.5 (a) The cascade of reactions biocatalyzed by ADH, AGS, INV, and GDH and triggered by chemical input signals NADH, acetaldehyde, maltose, and sucrose added in different combinations, (b) The logic network composed of three concatenated gates and equivalent to the cascade of enz3rmatic reactions outlined in (a).

In this case, three time constants in series, X, %2 and X3, determine the form of the final outlet response C3. As the number of tanks is increased, the response curve increasingly approximates the original, step-change, input signal, as shown in Fig. 2.12. The response curves for three stirred tanks in series, combined with chemical reaction are shown in the simulation example CSTR. 

The detector model is capable of simulating both vapour and liquid detection systems. So far, about a dozen different detector systems are available. The detector model input signal (see 2.1) consists of i) a time concentration profile, ii) the identity of the chemical warfare agent (HD, GB, VX or L) and iii) the relative air humidity (RH < 80% or RH > 80%). 

The group mind of termites is a machine for forming statistical assessments after sensing the surrounding environment. Perhaps termites find answers to their lives questions in the same way a computer determines statistical outcomes given a variety of input, or the way that our brains neurons collectively come to decisions as a result of chemically weighting a variety of input signals. 

Impulse (delta) response method The input signal is changed in the form of a delta function. This method is widely used in chemical engineering to investigate the residence time probability density distribution function. 

After a brief summary of the molecular and MO-communication systems and their entropy/information descriptors in OCT (Section 2) the mutually decoupled, localized chemical bonds in simple hydrides will be qualitatively examined in Section 3, in order to establish the input probability requirements, which properly account for the nonbonding status of the lone-pair electrons and the mutually decoupled (noncommunicating, closed) character of these localized a bonds. It will be argued that each such subsystem defines the separate (externally closed) communication channel, which requires the individual, unity-normalized probability distribution of the input signal. This calls for the variable-input revision of the original and fixed-input formulation of OCT, which will be presented in Section 4. This extension will be shown to be capable of the continuous description of the orbital(s) decoupling limit, when AO subspace does not mix with (exhibit no communications with) the remaining basis functions. 

The purely molecular communication channel [9,38,46-48], with p defining its input signal, is devoid of any reference (history) of the chemical bond formation and generates the average noise index of the molecular IT bond covalency, measured by the conditional entropy S(b system outputs given inputs ...
