SiC-AlN alloys were often produced by the carbothermal reduction of Silica and Alumina at above 2100 o C for long time[3-5].
Next, AlN vapor is deposited onto the surface of SiC grains and the AlN particle accompanied with reduction in the its size.
Not only the concentration of AlN was increased in proportion as the higher AlN content, but the reduction in SiC content would result in the decrease the concentration of SiC and the surface area of SiC grains.

Each data point shows an average of at least three valid testing bars.

In the case when the surface reconstruction leads to a reduction of the gap, HOMO and LUMO states (where HOMO/LUMO is the highest occupied/lowest unoccupied molecular orbital) are usually localized on the reconstructed surfaces.
Thus, we fit the PBE data with the function E(d) = 1.41 + A/dB (d in nm, energy in eV) finding A = 2.7386, B = 1.3722 (black curve in Fig. 2(b)), furthermore we could nicely reproduce the optical gap for small SiC NCs by adding 1.0 eV to this function (red dotted curve in Fig. 2(b)).
Indeed, our extrapolated value for the optical gap at d=3.9 nm agrees nicely with the experimental data.
We found a strong reduction of the optical gap for the small reconstructed SiC NCs.
Further investigation is needed to find the reason of the large reduction of the optical gap in that experiment.

This study concluded that the addition of relatively small quantities of a derivative of DBS lead to reduced space charges and a reduction in the size and number of spherulites.
The SANS Data was processed, including radially averaging, using the COLETTE Software.
Due to limited beam time we were only able to obtain data at the selected temperatures as shown in Figure 8.
In the case of the curves for 1% DBS/DPE there is marked reduction in the scattered intensity between 90C and 150°C.
The rapidly reducing nucleation efficiency of DBS above 120°C reported by Vaughan and Hosier [11] we attribute to the reduction in the volume fraction of DBS fibrils present in the sample and available to act as nucleants.

With the presence of bioplastic shielding, the image processed at a cut-off frequency of 5 (A) maintains good anatomical detail with slight noise reduction.
At a cut-off frequency of 10 (B), some noise reduction occurs, but the femoral outline becomes more prominent.
So that it produces the following data: Table 1.
This resulted in the Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) data as follows: Table 4.
The recommended cut-off frequencies of 5 and 10 provide the best balance between radiation dose reduction, contrast enhancement, and diagnostic accuracy.

Keywords: model test stand, laser measuring equipment, processing of experimental data, flow, flow velocity, turbulence, the velocity profile Abstract.
However, the process of obtaining the reliable data by means of calculations must be verified by physical modeling using modern methods of flow visualization on special research dynamic stands.
Its use is intended for the development of a uniform seed flow of reflecting particles (tracers) in the measurement and reduction of fuel expensive material tracers.
In this regard, the data given in this article are new, and we should expand our research relating to the study of counter eddy flows in a particular multilayer.

Investigating the property of metal dry friction damping can give many usable data for response analysis of damping blade which is important in damped blade designs.
The variations of friction coefficient of stick-slip area, equivalent stiffness and equivalent damping were calculated based on experimental data.
The effects of the material damping and the aerodynamic damping are not significantly on the turbine blades vibration reduction.
Fig. 3 Stationary friction specimen Fig. 4 Moveable friction specimen Data Acquisition and Analysis During the tests, the relative displacement u and the friction force f were measured under different exciting force amplitudes, exciting force frequencies and normal contact forces.

The completion time reduction for LU to decompose sub-task is not obvious, because the task of calculation has some data transfer and communication delays.
For the matrix inversion and matrix multiplication, with the increasing number of working machines, the task completion time is quick, because these two sub-tasks only are delayed in the stage of data transmission and data collection.

Common engineering construction accident of bored pile Hole collapse and diameter reduction.
Hole collapse and diameter reduction of cast-in situ bored pile was the two opposite faces on the surface, in fact, the causes were basically the same.
According to depth of geological data, combined with a comprehensive field sampling to determine,for non-rock type bearing, identify is more easily.
For the pile bearing stratum is intense weathering rock or medium weathering rock, more difficult to determine the rock interface, can use the method based on depth of geological data, combined with drilling rig stress, jitter of initiative drill and the sample in orifice to determine comprehensive, if necessary, take the in-situ core to verify.
In the 2#-A pile construction, geological data show that no cavities and holes at the pile position.

The upper and lower bounds of response variables are important because they determine the range of values that response variables can take, and they can be used to identify outliers or unusual observations in data [11] [12].
The results of condition optimization using Response Surface Methodology (RSM), widely applied for data optimization, involve a mathematical and statistical model.
This study investigates the reduction in CaSO4 scale mass in response to the addition of ATMP inhibitor concentration, temperature, and stirring speed.
This finding is consistent with previous [28], which reported similar reductions in scale formation when using phosphonate-based inhibitors.

The spectrometer calibration and data corrections for the high energy experiment are discussed.
This background spectrum is then subtracted from the Compton scattering data.
Before the data can be interpreted, a series of energy dependent corrections have to be applied [12-15].
The data reduction procedures were adapted from the software package created by the Compton group at the University of Warwick [16].
The agreement of the experimental profile with the free atom profile at high momentum indicates that data analysis procedure discussed above has been properly performed and that multiple scattering correction was correctly applied to data.
