The variations of residual stress caused by shot peening can be described by three sets of ordinary differential equations which have to be solved with the initial residual stresses and the initial plastic strain.
Then, it is quite reasonable that four IF THEN fuzzy rules are employed, provided that every fuzzy premise variable is described by two fuzzy sets.
We have previously proposed that var gene switching can be fully described dynamically by two sets of parameters ('Materials and methods' and [ Recker et al., 2011]).
On the other hand, although the general idea of degrees of membership agrees well with the general idea of true-false/one philosophy, we have to see in this approach that the dividing compressibility of sands into three levels, which are described by three fuzzy sets low, medium and high separately or partly overlapped, does not agree with the "one" philosophy.
The expression level of the gene At3g16910 coding the enzyme named acyl-activating enzyme 7 (AAEC; EC 6.2.1.1), responsible for the acetyl-CoA synthesis, is described by four probe sets and, among these, one belongs to cluster 1 (TaAffx.31783.1.S1_at, Additional file 5) while the other three were not differentially expressed.
In addition to this report, the phenomenon of T-DNA mutant instability due to trans T-DNA interactions was also recently described by two groups with different sets of mutants (Gao and Zhao 2012; Xue et al. 2012).
The FCI is graduated from 0 to 1 to indicate the integrity of the infrastructure, which is afterwards described by five linguistic terms or fuzzy sets.
Figure 9 shows the dendrogram generated by applying the agglomerative hierarchical clustering algorithm to the gene set described by four Alu-related genomic features and GC content (see the Methods section for details).
Anyone who fantasizes about the possibility of interstellar travel in the near future will be set straight by the daunting scientific reality, as described by one teacher.
