Figure 4 shows the interface state density of the SiO2/Nitride/SiC structure together with the data shown in Fig. 3.
Figure 6 shows the Si2p spectrum from the SiC surface with and without the direct nitridation layer detected at the same time as the data shown in Fig. 5.
Results shown in Figs. 5 and 6 and Table I indicated that the oxidation of nitride layer was the dominant process for the reduction of the interface state density.
The oxidation of nitride layer seemed to be the dominant process for the reduction of the interface state density.

The results show that the method is accurate and less time-consuming, and is able to recognize the fault pattern which does not exist in the fault history data.
In order to eliminate the dimensional impact, maximum - minimum standardized data conversion method is used in data preprocessing.
Data preprocessing consists of signal preprocessing, maximum and minimum standardized data conversion, and dimensionality reduction process.

Although monitoring devices have existed for some time, they have typically required a controlled environment, hard wired cables, and immense effort to obtain data making their application to civil structures difficult.
Furthermore, site-specific data greatly facilitates the adoption and implementation of performance-based design methods where the engineer is responsible for the characterization of all load and resistance parameters.
A concern in the adoption of these models has been that they require a great deal of input data to execute.
Such an approach requires the adoption of methods and metrics suited for probabilistic data and capable of quantifying the benefit of increased levels of safety over time.

Its data indicated that the structure of ZVI-SBA-15 retained the host SBA-15 structure.
The data in table 1 indicate iron nitrate’s role of aperture expanded.
The results have shown in Fig 6.The As sorption kinetic data are better fitted to pseudo-first orderreactions and fitted the expermental data (Fig 6), a fast sorption within 18h.

It is further confirmed with thermochemical data that the entropy and heat capacity of the system were enhanced at an elevated temperature.
Table 3 below shows the theoretical thermochemical data where AuCl2[C2H4O2]2- has the lowest enthalpy, corresponding with its ΔG value.

These thermochemical data presented are crucial in scaling the process from lab-scale to industry-scale application because the heat generated during the dissolution aids in sustaining the reaction temperature which promotes continuous gold extraction.
The thermochemical data further confirms that increased temperatures produce higher heat capacity and entropy values, favoring gold dissolution.

The porosity of syntactic foam is high, resulting in a significant reduction in weight compared to traditional materials due to the presence of hollow sphere fillers.
Strain data was obtained using an Instron extensometer of 25mm gauge length at a crosshead displacement velocity of 2mm/min. the raw data of load and strain values obtained from the MTS software are used to calculate and plot the stress-strain curves using Microsoft excel spreadsheet.
The raw data was plotted and calculated into stress-strain curves to obtain the flexural strength and modulus.
This was reportedly caused by relative reduction in density which is smaller than relative reduction in strength.
With the consistent progression in the σf/ ρ, with respect to HGM volume fraction, it shows that the syntactic foam can be of advantage in weight reduction application.

Based on the given data, an assumption has been suggested that organic substances with from one to three cyclic structures with aliphatic chain in which the number of atoms does not exceed 14 can be used as organic additives in the function of active compounds [6, 7].
