Comparison of experimental data of the fuzzy
logic controller type-2 and type-1 clearly indicates the superiority of the former, particularly in
reducing signal overshoots.
The difference between fuzzy logic membership function: a) type-1 (one triangle), b) type-2 [1] According to Fig. 1 output data is not constant as in type-1 but it constitutes a set of memberships that are fuzzy, and that is why it is often called the "fuzzy-fuzzy set".
For each α-plane centroid type-reduction by Karnik-Mendel algorithms is performed individually to obtain an interval.

The value of the specific surface area was determined from the data of nitrogen adsorption isotherms observed at 76 K.
Phase composition was analyzed with the use of data bases PCPDFWIN and full-profile analysis program POWDER CELL 2.4 and PDF 4+.
Step-like reduction is typical for all samples.

CBR solves a problem
very quickly since it only reads the training data without further processing[1].
In this study, a set of association rules with greater predictive capability is derived from the training data.
Let D be a training data set where each transaction has n distinct attributes A1, A2,…, An and a class label in G = {G1,G2,…,Cm}.
Any data with missing values are eliminated.
Whenever a rule does not classify any rows of the data, it will be removed because a rule preceding it has correctly classified its instances.

The high temperature of Pd reduction was observed for Pd/CeO2 and Pd-Ag/CeO2 catalysts.
Hydrogen absorption peaks with the maxima at 60 and 95оС may be assigned to the reduction of PdO fine particles, and the shift of palladium oxide reduction peak into the area of higher temperatures may be associated with both the small size of oxide particles (by XRD data, the coherent-scattering region for PdO phase is 4.2 nm) and strong interaction with the carrier.
The peak of hydrogen absorption at 405оС is presumably associated with the reduction of palladium silicate.
A similar pattern of silver and palladium reduction is observed for the samples based on aluminum oxide.
It is important to note that in the temperature area above 300°С the reduction of CeO2 is not observed in all bimetallic catalysts and sample Ag/CeO2, which is indicative of its reduction together with silver and palladium.

The experimental results was evaluated by the mass reduction and shrinking core models.
Aluminum with a thicker thickness can be approached with a mass reduction model.
While the mass reduction method examines from surface area and associated with the size reduction rate each time.
In addition, the mass reduction model also consider the purity of the aluminum.
The experimental data will be compared with the mathematical model.
