With the great volume of operation data, an fuzzy rough set (FRS) –based big data analytics were introduced to build the intelligent energy-saving decision-making model.
Big data-driven energy-saving decision-making model of thermal power units 3.1.
Energy-saving decision making model The proposed intelligent energy-saving decision making model are based on the great volume of practical operation data with big data analytics.
Such a method emphasizes the huge volume of data and implies that the collected data set covers almost the whole population as well.

The weight decrease on time, presented in Fig. 4 (the data is processed by methods of linear approximation) was fixed.
Under the received data the values of reactionary ability corresponding to these temperatures under the formula (14) are calculated as: For processing of experimental data, the mathematical procedure offered in the works [3, 16] was used
There is no data about equivalent or close correlation connection of the indicators CRI/CSR with technical and economic indicators of the blast furnace smelting.
In a certain zone of the furnace at a reduction stage of magnetite the reaction of wustite reduction tends to a thermodynamic equilibrium.
In this zone so-called zonal reduction realizes when the processes of reduction of various iron oxides combine in time.

The x-ray diffraction (XRD) data show that the reduction annealing process decreases c-axis length indicating successful removal of the excess oxygen.
Moreover, some studies claimed that the O(3) can be eliminated through the “modified” reduction annealing process [11–13].
Fig. 1 also describes that there are peaks that shift to a higher diffraction angle after the reduction annealing.
Similarly, the reduction annealing also provides an effect on the R distance.

The two main problems in data-based SHM are therefore: (1) If supervised learning is necessary, how does one acquire data corresponding to damage states of the structure
Basically, a statistical model of the healthy system is created, based on normal data and then subsequent data are tested to see if they are statistically consistent or inconsistent with the normal data.
The first SVM (labelled SVM0) seeks to separate damage-state data from normal-state data.
Confusion matrix for Classifier 2 applied to testing data.
Also concerned with the problem of sourcing data, a classifier has been presented that has generalised from single-site damage data to multi-site data.

Results and Discussion Reaction Mechanism of Catalytic Reduction of Nitrate.
Fig. 1 Hypothetical mechanism of catalytic nitrate reduction(*--the state of adsorbed phase) NO is the key intermediate on the selectivity of catalytic nitrate reduction [10].
Kinetics of Catalytic Nitrate Reduction.
Then equation (2) is simplified as: (3) Considering given conditions:when t=0, and , Equation (3) was processed by Laplace transform, then nitrate concentrations over time can be calculated by computer simulation as following: (4) In order to test for the proposal dynamic model, the experiment results from Fig.3 were plotted according to Eq. (1) and Eq. (4) to see whether a straight line passing through data can be obtained.
