The total reduction for these passes is
55%, calculated according to the thickness change.
This result is corresponding to the data obtained in the intermediate bar.
Secondly, the total reduction below temperature Tnr is not big enough, which is just 55%.
After experiencing 55% rolling reduction, the Sv increases to a range of 175~45mm-1.
The size distribution data of the precipitates is summarized in Fig.9.

Compared to this reference approach, a makespan
reduction and a setup time reduction can be observed.
Future research will focus on expanding the model and verifying its applicability on a larger data-set.
The proposed approach results in both a makespan reduction and a reduction in the number of setups.
For this mathematical model, good results can be obtained as far as makespan reduction, setup time reduction and reduction of the number of toolchanges is concerned.
On average a makespan reduction of 6% is observed.

The threshold voltage (VT) was calculated using the saturation extrapolation technique [3], from the data shown in Figures 2 and 3.
This technique was used as it gives the same order of magnitude for DIT, in comparison with the conduction technique [8] and, as this was an initial study, was only used to identify trends in the data.
The data for the nFET is shown in Figure 6.
This reduction in conductance indicates a reduction in interface trap density (DIT).
The total charge in the oxide layers (QT) is calculated from the observed flat band shift of the capacitance data from the theoretical values, giving -22 μC/cm2 for the nFET and 11.5 μC/cm2 for the pFET at room temperature.

This paper describes the structure and hierarchical analysis of granularity briefly, and then
details the construction algorithms currently, makes an emphasis on the merits of the various
construction algorithms, at the last summarizes applications in the rule extraction, attribute
reduction, cluster analysis, optimization theory, neural networks and fuzzy control and other
aspects.
Applications of Hierarchical Algorithm Hierarchy, having the advantages of reducing the computational complexity, is applied to rule extraction, attribute reduction, cluster analysis, optimization theory, neural networks, fuzzy control, and knowledge discovery and so on.
Attribute Reduction Granularity reduction algorithms imitate the granularity principle of human understanding for things changing, so that the knowledge representation changes from a single-level to a multi-level with all of the attributes in information system or decision-making system; correspondingly, hierarchy reduction changes from single-granularity to multi-granularity on the problem-solving.
Hierarchical attribute reduction problem is simplified by the hierarchy and has strong applications [12].

Next, multi-scale LGRPH is constructed for dimensionality reduction.
Introduction Synthetic aperture radar (SAR) image recognition remains as a hard task, while feature extraction plays an important role in it, which reduces the dimension of the data set while preserves the information useful for recognition.
Furthermore, for dimensionality reduction, we construct multi-scale LGRPH (i.e.

Rough Set Theory Poland Z.Pawlak professor, it is a data analysis tool.
However, the two problems: the best reduction is not unique and reduction computation time.
Rough set theory in data mining because of its classification ability of the tolerable limit Β.
Rough set theory is in order to analyze the facts hidden in the data without the need for any additional information about the data.
The basic algorithm can be obtained all of the reduction, but only suitable for very small data sets.

Therefore, the data reported by different authors are frequently not compatible
and cannot be compared.
These data indicate that the incorporation of fluorine into TiO2 results in reduction of the band gap.
This effect, however, is not consistent with the data reported by Alhakimi [22].
Data Compatibility The data reported by different authors may be compared only when these data are well defined in terms of the quantities that have an effect on photocatalytic properties, such as: 1.
Therefore, the data can be compared only for the same light source and the same light intensity.
