Results of column soil experiments are discussed and compared under similar conditions with literature data.
However, based on the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, higher ionic strength compressed the diffuse double layer causing a reduction in the repulsive electrostatic double-layer forces.

Although this can reach the purpose of data transmission, the timeliness is poor and data exchange error can easily occur so as to affect business.
Interact with specific data to release, search, signing, transaction and supervision operations.
When the company gains the authorization from the cargo owner and starts to transport the cargo, the company will upload the data in the data center in real time through mobile terminal for backstage processing and release entrustment data on data exchange platform of the data center to seek for convenient, fast, reliable and time-saving optimal truck team, confirm the ship schedule with the ship agency company, coordinate with the storage yard and the wharf for mobilization time and transmit documents and data to the customs broker or customs declaration company through mobile terminal and confirm letter of credit with the bank.
After the ship agency gains data information through mobile terminal, it can upload the data to the data platform in real time for processing ship entry or document inspection prior to entering the port.
JIT data exchange will shorten the stacking duration of the ships and cargo at the port.

In order to take into account the characteristics of flexibility and reduction of the retardation when connected, meanwhile, to meet not only the fixture complexity and availability (being easy) to manufacturing, but also to fit the strength and processing requirements, the systematic design is to create a tool system.
This structure to design three-dimensional structure of a parallelogram, shown in Fig. 4, is fixed at a,; and then, by using finite element analysis of the structure which adopts K value (N/μm) and H/D, weakening of the relationship between the analysis results, shown in Fig. 5, a further regression analysis of available relationship is therefore induced as follows: K=26.76× (H/D)-4.133 (1) Both the weakening of this structure and the analysis of a, b sides are tested to be able to provide with almost the same data; and it can be regarded as the structure of bi-isotropic, that is, after calculation, when fixed in sizes K value 20N/μm, the available H = 3.72mm, D = 4.28mm.
But the rigid values of the experimental data and analysis is still a difference of up to 50%, this error as the material on this set of error correction, can help to create a fixture of the correction.
This paper presents a flexible tool for the system design in order to get the desired function; and by using the experimental data of the displacement as a base for the modification of the parameters in analysis design with the increase of the production of fixture, it can establish a regression correction of the parameters; and thus, it can develop a systematic and extensive application of fixture purpose.

Based on the data of the band structure, DOS (Density of State) and PDOS( Partial Density of States), atomic populations and net charge, the influence on the energy band structure of the macrostructure of ZnO and La-doped ZnO was investigated.
It was assigned to the reduction of energy transfer which was caused by the gathering of rare earth ions in the boundary of grain and also the weak interaction of charge carriers and doping ions due to the lower solubility of rare earth ions in the ZnO materials [8].

He can also decide not to buy clothes because of salary reduction.
Its sales data tells the demand in the next year.
It is capable of learning the complex nonlinear relationships among the data and performs well with missing or incomplete data [8].
For ANN testing, the data in the first N time intervals are used as train data and the data in the (N+1)~(L) time intervals are used as test data.
All data are partitioned into nine subsets.

First TMS320VC5409 conducts convolutional encoding to the data, and then the data are interwoven and undergo OFDM treatment, including serial-to-parallel transform, IFFT operation, parallel-to-serial transform and obtains time domain signals; OFDM modulated analog waveforms are generated through D/A converters and shaping low-pass filters.
In the communication systems in the future, actualizing broadband high-rate data communication is a target people will keep pursuing, in which process OFDM technology can process the asynchronous characteristics of multi-body data business, provide larger capacity than traditional multiple access technology and can resist to channel frequency selective fading.
The principle of OFDM is to divide a high-rate data stream into several lower rates data streams, in favor of transmitting data in several subcarrier waves at the same time.
At the transmitting terminal, the high-rate parallel data from binary information sources first pass through signals encoded as MPSK, QAM, DPSK, etc., and then the encoded serial data undergo serial-to-parallel transform and high rate serial data are divided into N parallel data paths for transmission and the serial-to-parallel transform transmitting terminal sends out N symbols, which are modulated to orthogonal subcarriers of N to sum up N modulated orthogonal subcarrier waves and transmit them to channel transmission.
Chips are used in loading data and nonvolatile RAM of application programs.

Here for the coated samples, the coefficient of friction is approximately 0.3-0.4 in Fig. 2 c, d, which is a two-fold reduction from the uncoated sample in Fig. 2 a, b.
The mixed ceramic Al2O3-TiC with the new Ti-(TiAl)N-(ZrNbTiAl)N coating (Fig. 2 c), after 2000 cycles, had a reduction in friction coefficient down to 0.4.
This can be explained by a combination of inter-diffusion processes between the material being machined, resulting in a reduction in Al content and the Al2O3-TiC ceramic substrate.
As can be seen from the data, no delamination of the Ti-(TiAl)N-(ZrNbTiAl)N coating occurred along a scratch within the range of loads Fn applied on the indenter.
These contact stresses are generally high because of the considerable reduction of the total length of contact of the chip with the rake face of the ceramic tools.
