Shortwave leakage communication guide and transmit signals by means of leaky coaxial cable, in order to maximize the reduction of loss of signal transmission, the leaky signals need to be determined in the extent of shortwave and ultra short wave.
Second, design the wireless transceiver modules rationally, thereby ensuring effective data communication between every wireless sensor nodes, thus avoiding the manual routing, which greatly improves the efficiency of communication operations, making it convenient and simple.

According, the radial composite model can be used to interpretation the pressure transient testing data with considered sulfur deposition around wellbore.
Diffusivity ratio and mobility ratio respectively defined as: （1） （2） The sulfur deposition leads to the reduction of porosity at Zone 1.

Collect the Useful Data.
After clamping the cam blank which will be fabricated on the machine, start on the Bluetooth inverse engineering system, then we sample the outline of the cam on 0,1,3,5,7 points shown in figure 5 to get the sample data.
Process the sample data.
Calling the special calculate software such as MATLAB by the Bluetooth inverse engineering system, we can process the sampled data with curve fitting.
First, translate the relative coordinates into the polar coordinates, that is, give the function of the distance and rotate angle .And then input the data to two column matrix, polynomial fitting method is adopted to fit the sample data by using the curve fitting tool box.

Thus, chemical shift data allow qualitative and quantitative identification of the three major components of wood.
The reliability of the data is dependent on the shape of the droplet.
Fig. 15: Flexural strength at yield data of the PP Kenaf composites.
The authors observed that it was difficult to distinguish between materials that belong to the same class based on TGA data only.
The results show a good agreement between experimental and computing data.

Nevertheless, adding more than 15% cement by weight can cause a 28-day reduction in the concrete's strength, permeability, and porosity [19, 20].
According to data from the Ministry of Environment and Forestry of the Republic of Indonesia, fly ash waste from PLTUs in Indonesia was around 10 million tons per year in 2019.

Figure 1a shows the relationship between UCS experimental versus predicted values by EC2 model for both train and test data.
It should be stressed that the EC2 model predicted well both train and test data.
As we can see, R2 values are very close to the unit for both train and test data, which means high model accuracy.
Therefore, an important reduction of the costs can be achieved by limiting the number of formulations prepared.

One is to extend data sequence or to increase the extreme points on both ends.
The data corresponds to hourly average wind power measured in June, 2012.
There is a total of 720 data points.
Among them, there are 478 data points taking as experiment samples and there are 118 data points using for test.
The data of assessment index are shown in Table 1.

The costs of salt flux treatment have received a strong industry focus as solid flux addition has replaced the usage of Chlorine for alkali and inclusion reduction.
Field test data on influence of MgCl2 content on sodium removal Test data collected under carefully monitored and controlled conditions at a number of casthouses is presented as follows: Tables 1&2 show the comparisons made between a 40%MgCl2 and a 60-65% MgCl2 containing product applied manually in two identical 50 tonne furnaces at a smelter casting 5xxx alloy.
The eutectic low melting point area of the diagram is shown shaded in grey and the composition was selected to be in this range and comprising: Chemical data: Min % Max % MgCl2 37.0 42.0 % KCI 21.0 26.0 % NaCl 27.0 32.0 % Results of a thermodynamic study undertaken at RWTH Aachen A study was undertaken with IME Aachen, under Prof.
A fundamental study involving thermodynamic modelling using the Fact53, FTsalt and FSlite from FactSageTM data bases has demonstrated that it should be possible to add up to 25% of NaCl to a MgCl2 – KCl salt flux by substituting KCl without any effect on the residual Na content in the treated aluminium melt. 2.

The original data and parameters were record by the computer, then made use of the software of Microsoft Excel to carry on a data processing.
The reduction of ignitable material in proportion of volatile products caused EHC to fall.

It has recently been recognized that the two techniques can be integrated to produce more efficient tools for process variation reduction.
A model is appropriate for the data of a stationary process: Here, , .
