The Gallium nitride semiconductor and its alloy particularly AlGaN based quantum structures are having important applications in optical data storage systems and the visible displays.
In recent years semiconductor quantum wells have attracted growing interest for laser applications mainly due to their potential for a reduction of the threshold current density, and their increased gain and differential gain achieved by confinement since quantum confinement of carriers in semiconductor quantum wells [3-9] leads to quantized subband energies.

When selling timbers, the timber data will be read out from the computer.
When the log data collection sites is moved to the cutting area, the bar code data collection devices and associated equipment of the logs is necessary to reach harvesting teams, heavy investment in equipment increased the cost of bar code technology.
Usually, these data include: (1) Tree species; (2) Wood species; (3) Diameter class; (4) Length class; (5) Storage; (6) Storage plant; (7) Logging area; (8) Admission time; (9) Recorder; After logs left the yard, the log data must be recorded as the basis of the financial management, production planning and data management.
When the timber left the yard recorded data include: （1）unit price; （2）total sales; （3）Buyers and purchasing methods; （4）the time that the logs left the yard; （5）recorder; These records are indispensable data for yards to store logs and sales management.
And the yard must audit and statistics periodically these data.

The control message decides the client’s data transmission behavior.
The other trigger type of data-driven controls the data amount in each transfer.
The trigger type is data-driven and data mount is 500MB.

Therefore, a detailed data collection plan is required.
A good data collection plan should include: a brief description of the project, the specific data that are needed, the rationale for collecting the data, and how the data will be used once it has been collected [6].
One of the required data groups is standard processing times of processes.
As a result, collection of data is really a challenge and requires much resource.

The SAGS and the RMS surface roughness of the films calculated from AFM images data are shown in Table 1.
When the thickness increases to 30 and 75nm, the resistivity rapidly drops to (10.0±1.0) and (4.7±0.9)µΩ cm owing to the increase of thickness, decrease of voids and reduction of RMS roughness and ASGS, which decrease the surface electronic scattering, then avail electronic transfering.

According to the thermodynamic data, the calculated free energies of Mg, Al, Fe, Mn and La at 720�� proved the possibility of the oxidation of La to La2O3 and the simultaneous reduction of Al2O3�MnO�Fe2O3[8] As the reducing matter in molten magnesium, La mostly exists in the phase of La2O3 and partly in the form of Mg17La2.

Damage Model of Concrete Under Freeze-Thaw Cycles Concrete damage caused by freeze-thaw cycles is mainly manifested as the reduction of residual strength, elastic modulus and mass loss from macroscopic view, which is actually caused by microcracks evolution.
Although there were few experimental data of freeze-thaw performance of concrete under different freezing temperature, present researches have shown that concrete durability under freeze-thaw cycles is seriously influenced by freezing temperature.

Then rods were subjected to reduction, required to make rods with a square section.
In accordance with the TEM data, after the first ECAP-C pass a fragmented structure with low-angle misorientations is formed.

The reduction of Z1/2 and EH6/7 was attributed to the injection of carbon interstitials from the oxidizing surface towards the bulk.
The number of injected X can be estimated from the difference between the integrated depth profiles when annealed in N2 versus O2, and using the data for all doses this yields an average value of (1) A similar value is extracted from the concentration versus depth profiles for EH6/7.

The fitted results between experimental data and the functions revealed that the dielectric constant at 10 10 Hz was about 5.76 when the BN content was 15 wt.%.
The dielectric constants and losses of BN-AlN composites decreased with the increasing h-BN content, which was advantageous to the reduction of losses and heat productivity in the microwave vacuum tube at high frequencies.
