Wu. [40] In this result, we can be to conclude that ZGF nanocomposite effectively enhanced visible light absorption, which led generate electron-hole pairs using photo-reduction and photo-oxidation for photodegradation improvement.
Długosz et al [41], which results in the reduction of Fe3+ ions and tends to result in photocatalytic Fe3+ /Fe2+ redox cycle, under the solar light irradiation.
Thus Fe2+ ions are rapidly oxidized to Fe3+ ions by oxidizing with the oxygen molecules in the photo-reduction process, leading to superoxide radical anions (•O2- ) as a strong oxidizing agent in photodegradation.

And when h = 0.6 m, the selected data are the experimental results of Zheng Guanghong et al. [12].
However, the improvement of the gas flowing rate is bound to increase the cost of electricity, materials and noise reduction, at the same time the excessively-high velocity will cause great waste, so the significance of this paper is to give the best design of the size of the air flow cavity and the flowing rate of air in air purification device.

Although arc discharge strength indicates the high ion density of arc plasma, the specific data is rarely reported.
Design of the rapid scanning Langmuir probe system Similar to other probe measurement techniques, continuous improvement in measurement speed and accuracy and reduction in disturbance of measurement object are required in the development process of plasma diagnostic technique.
Steady-state plasma (glow plasma), due to its steady state, can be used to record and collect data at any time, therefore, the static measurement technique is used to measure the I-V characteristic curve of single probe point by point.
Meanwhile, when measuring the IV curves, the arc plasma state is volatile, which will definitely result in greater the error; therefore, the data should be recorded instantaneously, which requires the "dynamic measurement technology" to rapidly scan and measure the I-V characteristics.

The artifacts can be compartmentalized to four sorts according to the different exhibition forms: (1) Streaking, mostly caused by the unperfect detector, moving tested object, or data loss worked by metal, etc; (2) Shading, mostly caused by partial volume effect, scatter, or detector lag effect, etc; (3) Rings, mostly caused by detector gain non-uniformity, or unstable response, etc; (4) Cupping, mostly caused by beam hardening (BH).
If we can reduce the energy spectrum width of polychromatic X-ray to provide quasi-monochromatic beams, which consist of not a single X-ray energy but a narrow range of x-ray energies, the projected image quality will be improved from the source, especially have great significance for the reduction of beam hardening artifact.
For the dark field output fluctuations , the data under a local lead shield is accumulated, and the fluctuations on each line is computed and corrected line by line [7].
There are a series of scatter reduction methods reported.
We used noise suppression methods in the process of beam hardening correction included the following three aspects [13]: First of all, simplify the data based on histogram statistics of traversing lengths, which removing noise while ensuring the data density uniformity; Secondly, fit beam hardening curve by a stable fitting function, further enhancing the anti-noise capability of hardening model; Finally, correct beam hardening in order to primarily eliminate cupping artifact while control the image noises at the original level.

From point of view of crashworthiness, the main goal of UAV crashworthiness is minimizing the transferred acceleration to the high cost equipment inside the UAV, hence after the crash we should not lose the data which is collected during the missions.
Their study focused on the reaction forces in the important equipment due its high cost and function, for example, data which is acquired during the surveillance, terrain mapping, and reconnaissance are not to be lost in case of crash.
The next step after conducting the required FE modeling, is to perform many quality checks on the input data, and to carefully examine the output results.
Results and Discussions This study is focused on the analysis crushing response on the most important critical system inside the UAV fuselage which called “payload” due to its high cost and the importance of stored data inside it.

According to the thermal conductivity results of (U, Pu)O2, over the temperature range of 500–3000 K, can be obtained by physically mixing the data of NpO2, PuO2, and UO2 in some proportions.
Obviously great care is taken to ensure that discrepancies with experimental data are kept to a minimum during the fitting process.
The reduction in phonon mean free path from scattering is correctly associated with a non-uniform cation sublattice.
Purely small UO2 cluster was used to perform the initial MD simulation with small 324 ion cluster, promptly from the LAMMPS output data.
Such data gives a quite comprehensive comparison of lattice specification including thermal conductivity of MOX fuels through Molecular Dynamics (MD) simulation.

A reheating reduction of nearly 100% and time saving of 30% are expected.
Second, using the available data about shape, appearance and context, the constituents will be classified.
From the analyses of the steel grades, data sets on fractions, sizes, shapes, distributions, et cetera will be available for the occurring phases.
