In switch input and output, the use of the instruction redundancy methods to achieve the switch signal input and output filtering; in data collection, based on the hardware anti-interference taken arithmetic average filtering method, in order to strengthen its anti-jamming capability.
Summarizes the experimental phenomena encountered, the effect of interference on the work of the computer system can be divided into three cases, the first one is the data collection errors; second is control state failure; third, and most severe cases, can cause change the value of the program counter.
For interference may cause errors in the case of data acquisition, during the collection, the collected data can be low-pass filtering, as shown in equation (1) : (1) In equation (1) x is a digital filter input signal; y is a digitally filtered output signal; M is average filter points
Input data information in the interface are detected repeatedly, if the test results were in agreement, the input signal is true; if adjacent detected inconsistent, or more consistent test results, the input signal is false.

Comparative to the existing research, variable fuzzy clustering and comprehensive vulnerability index model are more objective in data processing and the influence of the clustering categories is reduced.
The study is used variable fuzzy clustering method to analysis the data of the disaster-carrying bodies’ vulnerability and build up an index model of the disaster-carrying bodies’ vulnerability.
Considering the problem to get data and the degree of influence of each factor, this study selects population density and investment in disaster prevention as indexes of social vulnerability.
Assessment of disaster-carrying bodies’ comprehensive vulnerability A certain city is taken as research object and 10 years of indicator data (2001-2010) is chosen for analysis.
The original data is showed in Table 1.

Fig 4. shows the thermodynamic software data plotted with the CCT diagram for A508-3 class 2.
The inability of the software data to predict the formation of ferrite may lead to a misrepresentation of microstructure and hence properties should the data be used to infer or predict transformations.
The results successfully represented the reduction in cooling rates as a result of latent heat release.
Dependent on the accuracy required the thermodynamic software data is still close enough to be deemed acceptable, especially in the absence of experimental data or access to DSC.

These models ensure that risk assessment procedures are up-to-date and responsive to changing hazards, as they can manage huge amounts of historical data and continuously learn new data.
In case of positive and negative results, if we find a discrepancy between risk assessments and the existing level of knowledge, we then provide the risk reduction data to AI for training.
The data acquisition module provides connection to data sources.
The LMS using this API will display this data in its interface.
AI-based disaster response platforms combine historical disaster data, intelligent video surveillance, sensors, satellite information, and social media data to support real-time emergency management.

PAC pavement is widely used because of its good noise reduction performance.
The grey entropy method can quantitatively analyze uncertain problems through less data, and quantify the degree of influence between systems and various elements within the system [7,8].
Therefore, the data of sound absorption coefficient in the frequency range of 500-1500Hz was used for further study.
As shown in Fig.2, the center of the image is the square center, and 1/5 of the total number of pixels of the total image is used as the datum length(b).

Then global rare earth supply reduction and speculation caused by Chinese rare earth management leads to the price rise.
China According to the US Geological Survey data, China’s rare earth total production from 1985 to 2011 is 1.803 million tons, accounting for 63% of the world’s total production.
Data from Chinese Customs shows that there are nearly 70 kinds of custom codes involving rare earth, so it is very difficult to estimate China’s rare earth trade.
In 2009 the United States’ exports of rare earth are 4 thousand tons, a 59% reduction compared to 2004.
According to the United States Geological Survey (USGS) data, in 2011 China’s rare earth reserve is 55 million tons, accounting for 48% of the global reserve, ranking first in the world, followed by the Former Soviet Union (16.70%) and the United States (11.43%) [5].

Formation of physical contact and setting corresponds to contemporary conceptions of solid body model and kinetics of development of connection strength by the data of the carried out tests.
For the purpose of heating time reduction and surface activation level increase the pulsed current from capacitors discharge is superposed on heating current
Optimal combination of properties, moderate micro-hardness and reasonable plasticity are determined also by Al content 10-12% in transition zone which correlates with literary data [3,4].

Because the gray forecasting model uses the method of producing data from raw data, it can wakens the randomness of the raw data and makes the newly forming data having some rule.
Data Selection.
Table 1 gives the data.
The fig. 1 gives more clear comparison between the real data and the forecasting data.
This may be because the oldest data has little relationship with the future data.

Smart meter performs power or electricity metering and has the capability of transferring key meter data via wired and wireless sensors.
The HAN is being developed from the need to facilitate communication and interoperability among electronic devices present within the close vicinity of a home or similar building structures, where smart appliances can be remotely controlled and monitored through a data concentrator and established a two-way communication to smart grid through an energy gateway.
Smart meter performs power or electricity metering and has the capability of transferring key meter data via wired and wireless sensors to form a simple Automatic Meter Reading (AMR) system.
Meter data management applications such as DLMS/COSEM and communications stacks such as ZigBee and PLC are all evolving to require larger amounts of memory and processor performance
Modern PLC networks can utilize OFDM (Orthogonal Frequency Division Multiplexing) modulation techniques to increase data throughput rates and reliability in inherently noisy environments such as electric grids.
