Thus, the moisture content (q) reduction rate in this period is usually small.
The moisture content reduction keeps at a constant rate at this period, and the rate depends upon air temperature, air velocity and atmospheric pressure.
Because of the process has a linear moisture reduction relationship with time, it can be modeled by linear heat transfer models that have been well developed in thermodynamic applications [4].

To ensure data accuracy, the experiment of blank control was repeatedly carried out three times and the average experimental data were taken finally
Adsorption data analysis.
The reduction of adsorbed Au(III) to its elemental form as shown in Reaction (1) creates active site vacancies for further adsorption, leading to an apparent uptake of higher amounts of gold.
The atomic weight, electro-negativity, ion valence and the standard reduction potential of Au3+were all greater than that of Cu2+.

Although, salt stress has been found to disrupt several physiological processes leading to reduction in growth and yield [13].
Superoxide dismutase activity (SOD) was assayed by the NBT method of Fridovich and Beauchamp [14].One unit of SOD was defined as the amount of enzyme required to cause 50% inhibition of the reduction of NBT asmonitored at 560 nm.
Data analysis Data are presented as the mean ± SE for each treatment (n = 3).
For two RGC germplasms germinated rapidly in distilled water(CK) during the initial 7 d ,but salinity caused a very significant reduction of the final germination percentage and also delayed the first germination time from 1 to 5 days.
Control plants of Zxy06p-2449 in SOD activity was not significant after treatment for 5, 10 and 15d, and between in 220-240U/FW.g. with salt concentrations increased, our experimental data shown that the activities of SOD was significantly increased after NaCl treatment compared with control plants, after treatment for 5 d, SOD activity in Zxy06p-2449 which were treated with 50, 100, 150, 200, 250mMNaCl, was 1.44, 1.45, 1.52, 1.14 and 1.71 fold of the control plants.

The EBSD data were collected from the regions near the sheet mid-plane of both grip and gauge samples, and used to plot and analyse the microstructurs using in-house software VMAP-V8.
Texture analysis was also performed using data gathered by SEM/EBSD work, where collected data were analysed using harmonic series, assuming cubic crystalline specimen with orthotropic sample symmetries, and used to calculate inverse pole figures of the tensile axis of both materials.
Graphs compare the change in HAGB spacing of the F300 and G300N alloys, in the presence (continuous lines) and that produced in the absence (dashed lines) of dynamic grain growth where straining results in grain thinning (reduction of grain spacing in the normal direction).

A small reduction in the misorientation angle used to discriminate HAGBs would remove the anomaly shown in Fig. 3.

In order to meet the needs of the high rate of data ,the big system capacity, coverage and low latency, LTE system supports MIMO, which includes spatial multiplexing, beamforming and transmit diversity and so on .Spatial multiplexing can increase the throughput of the system, beamforming and transmission diversity technology can increase the reliability and the coverage.
MIMO and OFDM technology, often referred to as MIMO-OFDM system,can meet the LTE in the high data rate, high reliability and other needs. resist the impact of multi-path fading as well.
In specific implementations, taking the complexity of the range into account to ensure adequate margin, will inevitably bring about the reduction efficiency of the algorithm and hardware implementation difficulties.
By (1) we easily to know: (5) Based on Max-Log approximation Estimates method, put (5) into (4), then LE can be simplified as: (6) Pass the calculated external information LE to the soft input soft output channel decoder, can solve the original data bit stream.
In addition, hardware implementation of the FCLSD algorithm could be carried out by parallel processing .When the antennas number more and the modulation order higher, the reduction of complexity will be even more impressive.

The information unit in the digital image is pixel, however, only the pixel data cannot be a good expression with the relevant geological information.
After loading the extracted feature data, the neural network is trained to obtain the output of rock texture classifications [8, 9].
For uniform image data, all images are obtained in the gray value mode.
Characteristics normalization and dimensions reduction.
Principal component analysis is a linear input dimension reduction technique, therefore it is needed to compute the largest eigenvectors of the covariance matrix of feature sets.

Mesoporous TiO2 onto graphene were reported to result in certain reduction of specific surface area of graphene[6, 7].
In the XPS data analysis, peak deconvolution was performed using Gaussian components after a Shirley background subtraction.
These binding energy data exhibit a positive shift of 0.2 eV and 0.1 eV compared to that in GO, probably due to diffusion of GO into the TiO2 lattice and formation of C–O–Ti bond in the samples, which changes the chemical potential and the polarity of GO[20,23].
These data demonstrate a certain degree positive shift compared to those in pure anatase TiO2 (458.1 eV for 2p3/2 and 463.8 eV for 2p1/2), indicative of more positively charged surface Ti4+, which may have arisen from the strong inductive effect of sulate and GO.
At the same time C-O bond increases from 22.9% to 29.5%, This fact may be explained by reduction of GO.

Another advantage in drilling of extended reach wells underbalanced is in the potential reduction in Equivalent Circulation Density(ECD).
UBD can, if effectively managed, provide an opportunity for a reduction in annular frictional losses and therefore minimise ECD problems by allowing the reservoir energy to push fluids out of the hole!
A few are however upscaled versions of classic mechanistic models modified specifically for the drilling process and tested against experimental and field data[7-8].
Drilling engineers live in a data rich but information poor environment.
