Modeling knowledge

Recent chemical modeling studies have been reasonably successful in reproducing the concentration-time histories of smog-chamber experiments. An examination of these models shows a need for much more detailed chemical knowledge. Modeling studies also point out the necessity of carefully defining the initial conditions of smog-chamber experiments. Some observations that have been made with these models are ... 

CmapTools is software developed and provided as a free download by the Institute for Human and Machine Cognition (IHMC). The CmapTools web site explains that the software empowers users to construct, navigate, share, and criticize knowledge models represented as Concept Maps. ... 

As we have seen in Chap. 2, such domain knowledge models can be layered, transitions between layers express e.g. class-instance relations (see CLiP in Sect. 2.2). There may also be clusters of related items, which are concatenated in partial models (again to be found in CLiP or OntoCAPE).

Figure 6 shows a structure of applying fuzzy logic in control. First, two types of inputs must be obtained numerical inputs and human knowledge or rule extraction from data (i.e., fuzzy rules). Then the numerical inputs must be fuzzified into fuzzy numbers. The fuzzy rules consist of the fuzzy membership functions (knowledge model) or so-called fuzzy associative memories (FAMs). Then the...

The coupling equation above is stiU strongly linked to the radiation field, including the respiration term. At obscurity (anywhere in the photobioreactor) or at a very low value of, 4(x), the maximal respiration rate must be considered constant and can be measured in independent experiments. In this case, the value of the new parameter K, is not independent because it can be deduced directly from the data on the specific photon absorption rate at the compensation point Ac (the other parameters known in our knowledge model) ...
