In many real-world applications, the isomorphism wotild be found before all 16 mappings were checked. For the example from Figure 6-3, many algorithms would find the isomorphism at the fourth mapping following the leftmost path in the search tree the bold line in Figure 6-4) ... 

For a pair of feature values a similarity value within the range from 0 (dissimilar) to 1 (identical) is calculated. For the comparison of two feature trees, the trees have to be matched against each other. The similarity value of the feature trees results from a weighted average of the similarity values of all matches within the two feature trees to be compared. 

After a strategic bond has been broken and precursor molecules have been obtained, a new level is added to the synthesis tree. Between two levels of the tree the synthesis tree branches out into precursors In addition, a new... 

The acacia trees produce gum arable only under adverse conditions, lack of moisture, poor nutrition, and hot temperatures. Gum arable is produced at wounded surfaces of the acacia trees. The wounds are generally produced deUberately in cultivated trees by stripping bark during the dry season. The gum is collected by hand over a period of several weeks with average yields of 250 grams per tree per year. Cmde exudates are hand sorted and exported before processing and milling to various specifications. 

It is not coincidental that the top event of the fault tree is the initiating event for the event tree. The fault tree shows how an event is decomposed into basic events whereas an event tree demonstrates the effect of the various safety functions. The disadvantage of event trees is that the outcomes are difficult to predict. Thus the outcome of interest might not arise from the analysis. 

Coconut oil [8001-31-8] is one of the primary vegetable oils used in the manufacture of soap products. Coconut oil is obtained from the dried fmit (copra) of the coconut palm tree. The fmit is dried either in the sun or over open fires from burning the husks of the fmit, with the oil pressed out of the dried fmit. 

The moisture content of freshly cut wood varies between species and portions of the tree. Between species, it can be 30—70% on a total weight basis (65) commonly, it is 45—50%. Within a tree, the heartwood generally has lower moisture content than the sapwood. For hardwood species, this difference is usually small for softwood species such as Douglas-fir, the difference can be as great as 30% for heartwood compared with 50% for sapwood. 

Commercial locust bean gum is the ground endosperm of the seeds of the locust bean (carob) tree. The general properties of locust bean gum are similar to those of guar gum. Differences are its low cold-water solubiUty and its synergistic gelation with kappa-carrageenan, furceUaran, and xanthan... 

Natural rubber can be obtained from the sap of a number of plants and trees, the most common source is the Hevea brasiliensis tree. Although natural rubber was known in Central and South America before the arrival of Christopher Columbus in 1492, the first use as an adhesive was established in a patent dated in 1891. As rubber became an important part of the industrial revolution, the rubber adhesives market grew in importance. To comply with the increasing demand on natural rubber materials, plantations of Hevea brasiliensis trees were established in southeast Asia in the early 20th Century, mainly to supply the demand from the automobile industry. 

To determine the minimal cutsets of a fault tree, the tree is first translated into its equivalent Boolean equations and then either the "top-down" or "bottom-up" substitution method is used. The methods are straightforward and involve substituting and expanding Boolean expressions Two Boolean laws, the distributive law and the law of absorption (Table 2.1-1), are used to remove superfluous items. 

A fault tree may either stand alone or be coupled to an event tree to quantif" bability. The top event in either case is the abjective of performing the analysis. If tht is the reliability of a system under specific conditions - then that is the top event. If it is to qua iify a node of an event tree the top event title is that of that particular node subject to the condi ons imposed by the preceding modes. 

In constructing the event tree, the analyst considers the functions that are required to prevent damage states, health consequences considering the relationships between safety functions. For example, if RCS inventory is not maintained, the heat-removal functions are depicted as failed state.s that may lead to core melt.

FEP, fault tree, gvent tree and piping instrumentation diagram (P ID) editor, accesses ihe package of graphical tools for risk assessment. These tools include the event tree, fault tree and P ID graphical editors. The event tree and fault tree editors are in PSAPACK the P ID editor is in FEP. The event tree editor is used for graphical construction and modification of event trees. The fault tree editor does the same for fault trees the P ID editor does the same for construction and modification of P IDs used in a PSA.

Answer End points 1, 3, and 6 are success paths which are not modeled by a fault tree. The fault tree for slow melt is Figure 15.3.1-1. 

The specific patli tliat an accident takes can be represented graphically by a fault tree. The tree begins witli tlie ultimate consequence and works backwards to tlie possible causes and failures.
