Phase composition of the sample cannot be obtained from XRD data, thus XFS data were recalculated and qualitative phase composition was proposed for the BFS sample (Table 2).
SEM data for mechanically activated samples of pure slag with no additives are shown of Figure 1.
DLS data for VEA-treated samples is shown on fig. 2.
Data obtained is shown on figure 4.
Compressive strength data (MPa) for various concrete compositions with different time of ageing.

Integrity detection technique is used to ensure the data integrity of network communication.
Authentication mechanism is that the data communication receiver can confirm the true identity of the data sender, and whether the data has been tampered in the transmission process. 5) Access control.
This layer mainly completes the perception and polymerization for data and information.
Application layer provides users with a wealth of specific services by analyzing and processing of perception data.
Wherein, security problem of middleware exists mainly from a large number of terminal data distributed processing security, illegal access, authorization management, etc.

In order to initialize the collapse in a stable way, the design of the impact attenuator was completed with a trigger which consisted of a very simple smoothing (progressive reduction) of the wall thickness.
The design of sacrificial structure has been completed with a trigger which consists in a smoothing (progressive reduction) of the wall thickness in order to reduce the resisting section locally.
In the current research, is chosen to be 0 due to lack of experimental data.

According to the conditions of irrigation area water supply and groundwater reduction for many years, the paper puts forward the optimal allocation and the supplying water programs on using combination of surface water and groundwater.
According to the data in recent years, 2006 - 2010 the Yellow River water has decreased, about 30% less than the same period average value.
Changing some parameters value in the model (each parameter is selected based on the experimental data or empirical data), it could work out the predetermined needs diverting water from the Yellow River and groundwater extraction at different time.
Calculating data will have better reference value that will increase the new water-saving irrigation area, improve the efficiency of irrigation water resource utilization, the rational distribution exploitation quantity of groundwater, effectively control the expansion of shallow groundwater funnel area, solve groundwater recharge and balance, analyze carrying capacity of water resources and so on.

Each set includes three specimens, and the average value of the three data was computed as the final result.
Method of Grey Relational Analysis Data Pre-processing.
Based on the above reason, ahead of implementing the present analysis, data pre-processing of transferring the original sequence to a comparable one is required [4].
In this study, the raw data were transformed into dimensionless forms by initial-value pre-processing.
As there are too many relational coefficients to be compared directly, further data reduction makes use of average-value processing to convert each sequence into its mean.

Such models based on building vulnerability often have high requirements for data.
Many models must be backed by complete data concerning building classification and population distribution.
The data on the buildings can’t be updated in time.
The death data of the four earthquakes are collected from official publications[27-30] (Table1).
The result shows that the three empirical models still have large errors compared with actual data.

The electrical properties of 0.01 mol%V2O5-doped ZnO varistor ceramics were measured by a DC parameter instrument, and after computing the test datas, the nonlinear coefficient is 25, the leakage current density is 0.02 µA/mm2 and the voltage gradient is 31.1 V/mm.
The electrical properties datas are summarized in Table 1.
The datas of the curve in the Fig.3 are consistent with the electrical properties datas in Table 1.
Moreover, a reduction of V5+ to V4+ would occur at high temperatures, and the V4+ ion has an ionic radius of ~ 0.61 Ǻ, which is close to that of Zn2+.

Introduction and Literature Review With the inception of Rapid Prototyping (RP) a complete revolution in manufacturing industry was witnessed as the RP could directly manufacture parts from computer data.
As .STL file is the universally accepted data format for giving input to any RP machine, the method uses .STL format as input and generates another .STL file of the required geometry.
Fig. 5 Process flowchart for phase -1 The data of these newly formed vertices, facets and facet normal are then arranged in a proper format that represents the.
All the five models were then fed to the Stratasys’s Mojo 3D printer and the data for material requirement and build time were captured using the Mojo software.
All the data is tabulated below: Table 2 Detailed result from the Mojo software Sl.
