In order to evaluate and mitigate the province from the agricultural natural calamities, the panel data from 1990-2012 of four agricultural natural disasters covered and affected areas are analyzed.
These data refers to the total of the above four main kinds of disasters, therefore other agricultural damages have not been included, for example typhoon, plant diseases, insect attacks, grass evils, rodents and rat harm, etc.
With the statistical data and information, we can give an initial analysis for the cases of natural disaster reduction and prevention.

The data are acquired spirally at the sampling
interval of 1 mm.
Result and discussion LS WT by filtering frequency, amplitude and both (combined method) are applied on the sample data to study their performance of noise reduction.
Fig. 12 shows the distributions of GBIR of (a) raw profile data and three profile data filtered at (b) frequency domain, (c) amplitude domain and (d) combined method.
Average values of all noise data are nearly zero.
Standard deviations of filtered noise are equivalent that of raw data.

Abstract: Currently, an environmental reduction factor (ERF) is incorporated in design codes/guidelines of Fiber Reinforced-Polymer (FRP) in reinforced concrete (RC) structures to account for the FRP long-term durability.
Due to the lack of real time durability data, justification of the ERF is still necessitated.
In the lack of real time durability data, accelerated ageing test was adopted to acquire the short-term ageing data, which is utilized to evaluate and predict GFRP long-term performance based on assumption that the Arrhenius time temperature relationship is valid for the whole temperature range considered [e.g. 2,12].
Huang (2011b) investigated the combined effects of 20% sustained load and environmental effects on GFRP durability in moist concrete, which showed a significant reduction in GFRP tensile strength [8].
For example, it would take 0.54 month at 20°C to give the same tensile strength reduction with that in April (1 month) in Beijing (13.1°C).

All this machines contaminate radio environment around them and make serious obstacles for WiFi data exchange.
Analyzing the curve presented in this figure we can notice that data transfer decreases four times in distance of 50 meters.
All data interchange between computer and AGV were done by this AP.
As a final effect we can observe stable (but not so high) data transfer rate.
It means that next data frames were supplied by different paths (not only straight way).
