Special application service data unit(ASDU) format.
Allow protection and control access to data across the bus segment.
In the point to point mode current data and voltage data are to be synthesized into a complete sampled data, which will be finally transmitted though fiber optic all the way to the protection, monitoring, metering and other equipments.
Only with data concentrator it can integrate the data of each bay combiner and export it.
When there are a number of bays it is a big challenge to both the data processing ability and the real time in data forwarding of the data concentrator. 3) Installation is not flexible.

IP-XACT standard provides a well-defined XML schema as meta-data that documents IP blocks and system designs, and defines an interface to make this meta-data directly accessible by automation tools[3].
A design flow for interchanging design components among different SoC design environments is described in[4] [5], which use the IP-XACT meta-data as the medium.
One 8K SRAM is also integrated in this subsystem for buffering several lines of pixel data for video process.
Peripheral Subsystem is composed of all modules for inter-subsystem communication, external memory controller and data transfer interface.
Ethernet MAC and USB Host/Device modules are used to support usual massive data transfer for audio, video and other applications.

Lignite contains more inherent water than traditional high-rank coals, which causes a considerable reduction of energy efficiency in combustion processes as well as transportation and thus is often uneconomical to be mined and generally used only for direct combustion [4-9].
All char yield data were repeatable within an error of 0.2 % ~ 2 % on the dry-ash-free (daf) basis.
The carrier gas is Helium with the flow rate of 10 ml/min. 2.5 Methods of data processing The Lower heating value (LHV) of the gaseous products is defined as[16], LHV(kJ/Nm3)=(CO×126.36+H2×107.98+CH4×358.18 +C2H4×590.36+ C2H6×637.72) (1) Where, CO, H2, CH4, C2H4 and C2H6 are the volume fraction of each product gas.
As expected, the increase in temperature resulted in the increasing gas yield with the reduction in the yields of char and liquids.

Taguchi DOE approach was chosen in the present study due to its favorable features, namely the possibility it offers to determine the effect of external disturbances considering the S/N ratio, which measures the interaction between the control factors and noise factors, and ii) its ready implementation, considering the simplicity in collecting data and the practical design.
a DF: Degree of freedom b Seq SS: Sequential Sums of Squares (measures the reduction in residual sums of squares provided by each additional control factor in the model).
c Adj SS: Adjusted Sums of Squares (measures the reduction in the residual sums of squares provided by each control factor relative to a model containing all the other control factors).
As shown in table 6, a suitable agreement between the predicted and experimental data was obtained.

Hence, the high-speed photography will be adopted to determine the initial fracture reduction in this work
Recent years, the increasing attention has been received with respect to near-alpha titanium alloys, and they have been researched as the candidate of material for jet engines as compressor discs and blades because of their light weight and superior fatigue and creep properties at elevated temperatures up to 600 ℃ [14].
Moreover, when the strain is up to 0.916, the observed cracking regions in the images are completely consistent with the practical situation, which manifests that the method for obtaining the critical fracture reduction is accurate and reliable.
It is interesting to find from Fig. 4 that the critical fracture strain data of the present alloy is divided into two parts as result of different values caused by different values (574.8 kJ/mol in α+β phase field and 194.0 kJ/mol in β phase field) [16].
Furthermore, the critical fracture strain data both in α+β phase field and β phase field can be well correlated with parameter.

The literature provides significant data on the oxidation resistance of coatings based on self-fluxing alloys produced using different surface hardening techniques.
Metallographic specimens were prepared using standard technology, which includes grinding and polishing operations with a gradual reduction in abrasive particle size.
The selection of temperature and holding time was based on the literature data [8,10].
Increasing the amount of “Nb+B” powder mixture added to the self-fluxing alloy to 35 wt.% leads to a reduction in the oxidation rate of the material.
