Symbolic knowledge processing

We learned the fundamentals about inferences on rule-based systems in Section 8.1 on symbolic knowledge processing. One possibility to infer on the knowledge represented in the computer is based on IF-THEN rules. In fuzzy logic, the premises and consequences are described by a fuzzy relation. Consider the following rules ...

This contribution presents a real-time knowledge-based system for the supervision of a multi channel FIA system applied in the on-line bioprocess monitoring of glucose, maltose, polysaccharide, ammonium, and alkaline protease measurements. In this contribution the special conditions of fault detection in a multi channel FIA system are explained. Examples of typical faults are given to explain how on-line symbolic knowledge processing can be combined with numerical analysis of data to perform a fast and reliable fault detection and fault diagnosis.

Some tasks in the Test of Gained Knowledge required students to connect observations about the macro course of chemical reactions with their notations in the submicro and/or symbolic types of representation. The results indicate that most students were able to rearticulate the information about reactants and products of a chemical reaction from the textual description of chemical reaction into the form of word chemical equation (textual description of macros word equation of macro Task 8.2, f(o/ )=89.82% Task 9.1, f(o/ )=87.61%). This action corresponds to the first step in learning to write down chemical equation in the LON approach. It can easily be explained, because teachers described the learning process to be very efficient to this point, as is illustrated below ... 

In practice, there may not be sufficient operating experience and resultant data to develop a numeric-symbolic interpreter that can map with certainty to the labels of interest, Cl. Under these circumstances, if sufficient knowledge of process behaviors exists, it is possible to construct a KBS in place of available operating data. But the KBS maps symbolic forms of input data into the symbolic labels of interest and is therefore not sufficient in itself. A KBS depends on intermediate interpretations, ft, that can be generated with certainty from a numeric-symbolic mapper. This is shown in Fig. 4. In these cases, the burden of interpretation becomes distributed between the numeric-symbolic and symbolic-symbolic interpreters. Figure 4 retains the value of input mapping to preprocess data for the numeric-symbolic interpreter. 

Among the hidden knowledge in the Golden Dawn s synthesis of symbolic systems, alchemy was crucial. It represented a link to the past, to a world in which the processes of nature bowed to the spiritual power of purification practiced both by and upon the alchemist. 

Since all is ultimately consciousness, mind (as Buddhist metaphysics terms consciousness) is the builder of all and the source of the illusion of separateness. It is by the skillful use of the image-building faculty of consciousness (imagination) that we fashion the tools for our liberation. The subjectivity of inner vision does not diminish its reality value. It is real on its own level. Such visions are not hallucinations, because their reality is that of the human psyche. They are symbols in which the highest knowledge and the noblest endeavor of the human mind are embodied. Visualization is the creative process of spiritual projection, through which inner experience is translated into visible form, comparable to the creative act of an artist whose subjective idea, emotion, or vision is transformed into an objective work of art which then takes on a reality of its own, independent of the creator. 

The resistance of the electrolyte, Ra, represents the ohmic resistance of the complete column of electrolyte between both electrodes. Note that in this way of presentation, the Faradaic impedance cannot necessarily be correlated with an occurring process, therefore it is represented by a general symbol ZF. It can be seen in this case that the total impedance consists of contributions from the working and the counter/reference electrodes, and knowledge of the behaviour of only the working electrode needs manipulation. A simple possibility is to use a CE/RE electrode with much larger surface than the WE. However, in the work presented in this book, this manipulation is not done, because the system used here will be used in applications as a set of two identical electrodes. In addition, one of the parameters that we are interested in is the electrolyte resistance, a parameter that is suppressed when using electrodes of different surface areas.
