Data acquisition The data acquisition function of the discrete manufacturing industry production execution management system is responsible to gather produces in the scene each kind of real-time renewal data message, and for other enterprises the data management to provide the data pool.
The data type divides into craft resources data, human resources data, product quality data and so on according to management way.
RFID data acquisition middleware The data acquisition middleware is connected the electronic label reader-writer and the enterprise application software link, it is managing the electronic label reader-writer and enterprise application software data stream, and there is responsible to the data security, accuracy, validity.
Data acquisition middleware has safety control, data buffer, data filtration, production data pool, reader-writer connection and application program interface and so on.
(4) Application program interface The RFID data acquisition middleware may provide many service connection for the application procedure, in which most basic including obtains the data message and renews data message.

For the case of China, as for the GHG reduction pressure, China is planning national GHG reduction actions besides preparing for the restoring international cooperation mechanisms.
GHG Emission Reduction baseline is set according to investigation of building industry.
Data is mainly collected from the published international and Chinese documents, and local contacts at architecture design practices [9].
Microeconomic efficiency and GHG emission reduction is calculated using interpolation algorithm.
Emission reduction of low carbon scenario is 0.68×106t, and emission reduction of ideal scenario is 1.36×106t.

Carbothermal Reduction and Nitridation of Quartz Mineral for the Production of Alpha Silicon Nitride Powders A.
In this study, α-Si3N4 powder was produced by carbothermal reduction and nitridation (CRN) of quartz from Can-Canakkale.
The carbothermal reduction method (Reaction 1) starts from a mixture of SiO2 and carbon, which is then reacted to form α-Si3N4 powder between 1400-1500°C in flowing N2 [6-9] or to form SiAlON powders [10].
Data from the chemical analysis and X-ray diffraction showed that the quartz consisted mainly of silica (Table 1).
Conclusions Technological ceramics such as Si3N4 based ceramic powders could be produced easily from widely available raw quartz mineral powders by the carbothermal reduction and nitridation (CRN) process.

Dynamics Characteristic Analysis Based on Component Mode Synthesis Method The substructure analysis uses the technique of matrix reduction to reduce the system matrices to a smaller set of DOFs.
Matrix reduction is also used by the reduced modal, reduced harmonic and reduced transient analyses.

-field data for sample NMG1 for three piezo frequencies at drive voltage of 30 Vp-p.
NMG2 NMG1 The relatively large scatter in the data in Figures 7 - 12 reflects the stochastic nature of twinboundary motion; twin boundaries that move in one actuation event intersect different pinning sites in a subsequent actuation [12]
-strain data for sample NMG2 under an application of piezoelectric actuation with 30 Vp-p and varying frequency [17,18].
The approximate amplitude of the stress wave expected from the piezo stack is calculated from the data in Fig. 16 using Eq. 8 (see Fig. 17).
-σbias data, with and without acoustic assistance, are plotted in Fig. 21.

The world market produces a wide range of coatings, applied in limited thickness, transparent and opaque, high initial performance, although data on their durability are still missing.
The evolution of Luminance of samples artificially aged Data show that the coordinate b* increases progressively towards yellow, while the coordinate a* is kept constant.
The procedure of the time rescaling, as codified by ISO 15686 and UNI 11156, was followed, representing the comparison of data derived by artificial aging, with the measured data in outdoor conditions.
The data of photocatalytic activity to one year of natural aging are not yet available.
Additional data may clarify the decay characteristics of the product.

Modal parameters were identified from the measurement data using the pLSCFD (polyreference Least Squares Complex Frequency Domain) [6] and the ERA (Eigensystem Realization Algorithm) [7] methods.
Comparison of the FRF sum obtained from measurement data and the synthesized FRF sum based on a) p-LSCFD and b) ERA method An important step of the modal identification validation is comparison of the synthesized FRFs for every accelerometer position with the FRFs obtained from measurement data.
Once modal parameters were identified on a basis of the measurement data, the FEM model parameters were tuned.
Normal modes identified from measurement data and calculated with a use of the FEM model were compared by a modal assurance criterion (MAC).
During the process of calculation, the frequencies obtained from experimental data were used.

The reduction of the total machining time of a workpiece on a machining centre is obtained through: the reduction of the machining time, reduction of tool and workpiece changing time.
The reduction gear box isn`t chosen and the parameter which we consider is the acceleration of the mobile element, namely the pallet.
We initially consider that reduction gear box gears inertia is negligible and so are the friction moments and the inertia of the drive chain coupled with the reduction gear box`s shaft; the transmission efficiency is considered to be ideal, η = 1.
Therefore the geometrical spot of the maximum transmission ratio when the mechanical data is varied is a straight line which passes through the origin.
Conclusions The productivity of machining centres is increased through the reduction of auxiliary times of changing tools and workpieces.
