If a display function of voice prompt is needed, audio materials, floor information are saved in database system, in which information corresponding to user instructions can be displayed through data analysis[5].
Through the network realization and object data communication diagram.
The virtual product propagations bring out the reduction of operation costs and the increase of product benefits, and satisfy the customers of the requirements for systems with real-time, interaction and immersion behaviors, and it also can bring out practical applications.

The other factor is that there was only one tile tested and it is necessary to test more specimens for getting the needy statistical data [7], [11].
Improvement of the hydraulic equipment has been planed so that the data could be at disposal.

It is shown that redesign of an old network based on the proposed method leads to 49.7 m H2O reduction of the hydraulic losses, due to sizing of new pipes in accordance with real heat consumption.

The brittle and hollow nature of fly ash cenospheres in the matrix also contributed to the reduction in hardness and density of the samples as seen from Fig.3 and 4.
The development of finer microstructure in the microwave sintered samples lead to better erosion loss which is about 12 to 15 % over its counterpart. 3.3 Dry Sliding Wear: The slide wear data have been obtained for the microwave sintered samples (M1 to M4) and conventionally sintered (C1 to C4) samples for applied loads of 1, 2 and 3 kg, slide speed of 200 rpm, sliding distance of 6000 m over a hard alloy steel disc of 62 HRC with a surface finish of about 10 µm.
The SEM picture corroborates the slide wear data in terms of grain morphology.

（6） （7） (2) When the algorism entered the period of data analysis, we need to calculate the rising of the iteration K[n] and the absolute difference e(n), then the weighing parameter, and in the end amend the value of the P[n]
（8） （9） （10） (3) In the end, we deal with the sampling data u(n), and get the best weighing parameter after numerous iteration like this
The reduction of calculation is a main aspect to improve the algorithm.

The implementation of GB/T 7607-2010 criteria for changing of diesel Engine oil formulate the drop in the rate base value limit of 50% since May 1, 2011. [2] Test Most lubricants contain alkaline additives by the calcium, magnesium and other metal ions with various organic acid surfactant (alkylbenzene sulfonate, alkyl salicylates, etc.) posed.

Fly-ash particle reinforced Al matrix composites have outstanding functional properties such as high specific stiffness, better energy absorption and vibration reduction performances, fine sound absorption capacity, excellent heat-resistant and electromagnetism-shield properties[1,2].
The data show that: Compared with composites without suspending agent, the hardness of fly-ash particle reinforced Al matrix composites amount increase with the content of suspending agent increasing. when the content of suspending agent is 3%, the hardness of the composites reached the maximum (HBS121), compared with composites without suspending agent, the hardness increased by 13.1%.
The grinding ring is made of GCr15 steel, the test load is 300N, the speed is 0.5m / s, the stroke is 90m, each sample was grinded three times and the average test results are shown in Table 2, the data show that: compared with composites without suspending agent, the wear resistance of fly-ash particle reinforced Al matrix composites amount increase with the content of suspending agent increasing. when the content of suspending agent is 3%, the wear resistance of the composites is best, compared with composites without suspending agent, the weight loss decreased by 20.10%.

The reduction in thickness range is most likely due to additional bombardment of the inner layers due to the extended spray time.
A significant result from the data is that all spray pressures and the lowest two temperatures produced coatings with significant areas of exposed steel, Fig. 2a.
Scanning electron micrographs of (a) Al-50wt%Zn, and (b) Zn-20wt%Ni coatings; (c) EDX elemental mapping data indicating the initial and final coating compositions.

However, real ACFM signals always contain much interference noise, thus it is of critical importance for the noise reduction.
Since it is a fully data-driven method, the results will preserve the full nonstationary characteristics of the ACFM signal.
It can be seen that the original ACFM signal may provide misleading defect trace signals due to the complex nature of the crack or the noise pollution from measurement, data collection, experimental error, etc.

A source code programming is developed in the present study while the input data is referred to the previous researchers [8].
The calculated transmission loss is then compared with the published data in order to verify the developed source code.
Based on the analysis of mufflers, both of the baffle thickness and baffle location is found for noise reduction.
