An intriguing feature of the point distribution in this plot is the occurrence of single, double and intermediate N1—C2 bonds for the low values of /Ni and of only single N1—C2 bonds for high values of /Ni. This behaviour may be schematically represented by the simplified graph shown below, in which arrows symbolize observed logic relations.

Quantifier, i.e., 0.9 , which is one of many generalised quantifiers in observational logic. The parhcular quantifier - p employed in the above rule is called founded implication and expresses the fact that among those objects in the available data that fulfil the condihon of the mle, at least the proportion p also fulfils its consequence (in the above rule,/ = 90%). 

Blackout problem if the instrument does not properly work, it is difficult to observe intermediate states. Very sophisticated instmmentation is needed to measure voltages, currents or logical levels on the boards of the instrument. 

The scientific method is taught starting in elementary school. The first step in the scientific method is to form a hypothesis. A hypothesis is just an educated guess or logical conclusion from known facts. It is then compared against all available data and its details developed. If the hypothesis is found to be consistent with known facts, it is called a theory and usually published. The characteristics most theories have in common are that they explain observed phenomena, predict the results of future experiments, and can be presented in mathematical form. When a theory is found to be always correct for many years, it is eventually referred to as a scientific law. However useful this process is, we often use constructs that do not fit in the scientific method scheme as it is typically described. 

Self-Organizing Fuzzy Logic Control (SOFLC) is an optimization strategy to create and modify the control rulebase for a FLC as a result of observed system performance. The SOFLC is particularly useful when the plant is subject to time-varying parameter changes and unknown disturbances. 

The most logical suming point in tlie safety design approach is to select a site where tlie number of undesirable weather and topograpltic conditions is limited. Adequate utilities and support systems plus fire protection service arc also required for a safe eiiviromnent. Chapter 5 presented a detailed account of phuit site selection and layout. These features will now be considered from a safety point of view. The following guidelines should be observed in dctcrniining a site tliat is favorable for tlie efficient tuid economical operation of the process. 

The purpose of the various electromechanical elements of a circuit is to effect monitoring, safety and automatic control, and these may he connected separately into a custom-huilt system. The availahility of electronic logic circuits gives the possibility of integrated systems and superior control, using a large number of input signals. Observed parameters are ... 

Training courses are available in analytical methods of fault-tracing. Computers are also in use which monitor a number of parameters and draw attention to any observed abnormality. The control/ monitoring device may then make a judgement as to the cause, or this may rely on the interpretation of the operator. Considerable use is now made of logic control/monitoring devices which can oversee the operation of a large number of installations from a central computer/observation terminal. 

The first observation consists merely of an alternative but natural interpretation of the presence or absence of balls the movement of balls is equated with the communication of binary signals. Once this interpretation is made, the second observation also becomes a natural one wherever balls collide, either among themselves or with some collection of rigid mirrors, the effect of the collision may be viewed as a Boolean logic gate. 

This procedure is one of the elementary logical thought processes by which information is systematized. It is called inductive reasoning, and it means that a general rule is framed on the basis of a collection of individual observations (or facts )- Of what use is the inductive process It is an efficient way of remembering. 

An argument can be made that chemistry is a critically important science for understanding the causes and effects of much of the environmental change observed today. Consider the logical progression of ideas already discussed, i.e. 

As the WT CHMO was known to react (S) selectively with simple four-substituted cyclohexanone derivatives [84—87], it was logical to test mutant 1-K2-F5 as a catalyst in the BV reaction of other ketones. For example, when 4-methoxycyclohexanone (38) was subjected to the BV reaction catalyzed by mutant 1-K2-F5, almost complete enantioselectivity was observed in favor of the (S)-lactone (39) (98.5% ee), in contrast to the WT, which is considerably less selective (78% ee) (see Scheme 2.11) [89].
