Tree diagrams

A simple example of fault tree analysis applied to an internal combustion engine (Figure 3.4.4-2) is the Figure 3.4.4-3 fault tree diagram of how the undesired event "Low Cylinder Compression" may occur. The Boolean equation of this fault tree is in the caption of Figure 3.4.4-3. Let the occurrence of these events be represented by a 7, non-occurrence by 0, and consider that there may he a long history of occurrences with this engine. Several sets of occunrence.s (trials) are...

The OWR protective systems were modeled with event tree diagrams for the time sequence following an initiating event to fuel damage or safe shutdown. Fault trees were used to find the probability of failure of each protective system in a particular event tree.

The IEEE Std 500 document is based on a hierarchical structure of component types set down in the manual s table of contents. The preface for each subsection (defined by a component type) provides a tree diagram that clearly shows the way the component classes have been subdivided to determine "data cells". The failure modes for each component class are also hierarchically organized according to failure severity catastrophic, degraded, or incipient. Rates per hour and demand rates (per cycle) are both included, as well as upper and lower bounds.

Active Figure 13.20 A tree diagram for the C2 proton of frans-cinnamaldehyde shows how it is coupled to the C1 and C3 protons with different coupling constants. Sign in at www.thomsonedu.com to see a simulation based on this figure and to take a short quiz. 

Problem 13.22 3-Bromo-l-phenyl-l-propene shows a complex NMR spectrum in which the vinyli< proton at C2 is coupled with both the Cl vinylic proton (J - 16 Hz) and the C3 methylene protons (/ = 8 Hz). Draw a tree diagram for the C2 proton signal, anc account for the fact that a five-line multiplet is observed.

Classification process - such as a tree diagram that shows how different things can be categorized from the most general to the most specific terms. 

Tree diagrams are an excellent checking device to ensure correct balancing of all chemical equations in a plan. 

Experimental protocol is built into the construction of tree diagrams so that intermediates that are isolated are distinguishable from those that are made in situ, and the order of input dots matches the order of addition of reagents used in the synthesis plan. 

As an illustrated example of these ideas presented thus far we show in Scheme 4.8 and Figure 4.14 the conventional synthesis plan for triclosan and its corresponding synthesis tree diagram.

These kinds of calculations are easily done when a tree diagram is constructed for the plan. The Schreiber plan which proved the structure of the final target molecule has the highest degree of convergence since it has 3 points of convergence and 4 branches or paths in its tree diagram.
