One-way analysis of variance (ANOVA) was conducted to analyze the data and the mean comparisons were run by Duncan’s multiple range tests at P < 0.05.
The significant reduction of the WVP the film materials when it contained nano-SiO2 could be explained as that the nano-SiO2 particles had a low water solubility compared with the gelatin and chitosan, and the pathway of water vapor were tortuous caused by SiO2 nano-particles.

(2) Under different levels the creep compliances meet the following equivalent relation by reduction time
(3) Therefore, the long-term creep properties under low stress of non-linear viscoelastic material can be achieved by short-term creep data under high stress.

We can determine the offset distance d between the underlying mould cavity surface and the cooling layout from the theoretical calculation or practical data[5].
The range of the average temperature (between minimum and maximum temperatures) of VRCCC (48.1 o C) is kept narrower than the CCC (59.68 o C) one, a reduction of 24%.

Construct unified data platform Due to long-term lack of unified and effective planning and leadership department of traditional colleges and universities information construction, colleges and universities departments form independent college information application system and information isolated island, and gradually form stable data repository, but resources data are unable to achieve full sharing between subsystems, which is no good to the uniform data query in colleges and universities, and data applications.
Wisdom campus basic task based on the Internet of Things is to make full use of the campus existing application system and information data to construct a unified data reception.
And the key of wisdom campus construction is to establish a unified platform for data fusion, accomplish campus data resources integration and sharing of information management, and provide users with high-quality service data fusion.
Wisdom campus data come from other entities related to learning teaching in addition to information relating data from school business administration.
Due to different entities have different heterogeneous data sources and management mechanism, the lack of unified platform data sharing will not provide good data fusion for campus user services.

Through data acquisition (Hantek DSO3000A) process, the data is extracted to frequency domain commonly applies a digital signal processing technic which is called a Fast Fourier Transform (FFT) [3].
FFT was applied to the DSP data derived from the impact-echo data to obtain the maximum amplitude of the signal.
Data recording from these three accelerometers was gathered by a data acquisition (Hantek DSO3000A) and transferred to the computer.
In this study, FFT analysis was combined with the magnitude-squared coherence method in order to get quantitative data.
As the reference data, the result from the vibration measurement from P1 is presented in Fig. 1.

This extends the time required to process each data point, subsequently resulting in longer scan times.
Furthermore, a Hough transformation may already bias experimental data.
EBSD data collection adds significant overhead of typically 1 hour per slice to the time required to lay open and analyze a section slice, because of the relatively slow speed of online acquisition of orientation data with conventional systems [4].
Therefore, automated EBSD data need to be treated with caution in materials with high rates of misindexing and/or nonindexing [5].
The patterns are stored in raw bitmap format on the hard disk after binning on the sensor chip rather than as reduced data ("Hough" peaks).
