Experimental data were acquired and recorded by an optimally designed network of sensors.
Experimental data were statistically analyzed in order to reach conclusions.
Experimental Setup The data acquisition system is established in a two axis lathe, model AFM TUE-40, accommodating workpieces of length 1000 mm and diameter 600 mm respectively.
The second experimental data set concerning cutting with cutting fluid highlighted that the level of vibrations is around 6 m/sec2, having an average value of 6.66 m/sec2.

Interpretation of experimental data is based on Stoner-Wohlfarth coherent rotation approach.
The interpretation of the experimental data is based on the Stoner-Wohlfarth approach.
Using the data of Fig. 2 we found the angles at which the transition takes place; they are shown in Fig. 3 with solid circles.
Figure 4 shows the low field parts of the MR curves for magnetic field directed along PD or EA in comparison with the data for the unannealed sample with MF || EA || PD.
So it is the deviation from PD direction that is the reason of coercivity reduction.

Existing nitrogen oxides (NOx) control technology primarily depends on selective catalytic reduction (SCR) method.
The total NO removal efficiency formula used for experimental data analysis in this paper is defined as follow: η= (1) Cin: Initial NO concentration.
N atom cannot react directly with C2H4, the way to remove NO is still the reduction reaction 3.
The experiment data in NO/N2 system is added for contrast.

Silicon carbide (SiC) powders have been prepared at 1200-1500°C by carbothermal reduction
of two kind precursors of carbonl/silica mixtures: coked rice husk with high-carbon content, and gasified
rice husk with low-carbon content mixed with carbon powders as an external carbon sources.
The external carbon source is commercially available carbon black powders (CBp,specific surface area[m2/g], average diameter 40 ~ 50 nm).Table 1 presents data on the chemical composition, SBET obtained of these ashes.
To clarify the effect of the nature of carbon on carbothermal reduction, BRHA,a inherent precursor without CBp was prepared in the same way.
The difference of silica structure in two systems would also affect the rate of SiO(g) formation from the reduction of SiO2.
XRD pattern of the powders from system 2 synthesized at various temperatures for 4 h area of the amorphous carbon, and helps in the carbothermal reduction of silica.

The binding energy data of C1s, Cu2p3, Mo3d5 and O12 are listed in Tab.1.
The binding energy center of MoA is 233.7ev, which is coincident with MoO3; and the binding energy center of MoG is 232.65ev, which is between the binding energy data of Mo in MoO2 and MoO3.
It could be inferred that reduction reactions occurred in this period.

The article considers the dependent process steps with attributes data.
However, the multivariate control charts dealing with discrete data are lacking.
Therefore, this research will focus on the dependent process with attributes data.
Design of the VSSI Charts We considered a process with the two dependent steps of attributes data.
Base on this, we used VSSI scheme to monitor the dependent process steps with attributes data.

Using the elimination strategy, the primary vibration source was determined, the vibration serviceability of the residential building was assessed by the environmental vibration tests, and the measures for vibration reduction were proposed.
By applying the measures for vibration reduction to Mill Ⅱ and reinforcing the residential building, the vibration serviceability can be improved. 1 Introduction A residential building, constructed by brick-concrete structure and completed in 2001, is six-layer and two-household with a storey height and a building area, respectively of 3.2m and 960㎡ in each storey, whose floor plan is shown in Fig1.
(2) Vibration reduction measures should be applied to improve Mill Ⅱ
