In the course of this ongoing collaboration, the organization and dissemination of information and data play a key role.
Therefore, it is necessary to introduce data filtering function during the transmission of information flow between the various departments.
It has three main functions: (1) collect related data and information of disaster from the public, media and specific experts; (2) organize useful data; (3) send the necessary final filtered metadata, data and information to its subordinate.
In all stages of the disaster management process, the applied information and communication technologies includes the internet, information security, computer databases, integrated data management, intelligent data management, audit tools, multi-agent systems, multi-language support, data filtering, mobile communication technology, wired communication technologies, and wireless communication technologies.

Knowledge reduction is one of the most important contributions of rough set theory to machine learning, pattern recognition and data mining.
So, quicker methodologies for attribute reduction are better for huge data processing.
Experiment Results In the first experiment, the uci KDDCUP99 data set is used. 10%, 20%, 30%, …, and 100% records of the KDDCUP99 data set are selected to create a testing data set each time respectively.
Half (50%) of the entire data set was split as and used as the training data set, while the remaining 50% was used as the testing data set.
This attribute reduction algorithm can process huge data sets efficiently.

The Analysis of Dynamics Incenting incentive on Enterprise to Energy Saving and Emission Reduction
The so-called dynamics incenting enterprise to energy saving and emission reduction are the driving force which can promote enterprises voluntarily and positively behave on energy to conservation and emissions reduction.
The concrete analysis results are as follows: Table.1 lists related data from 2005 to 2010 of industrial enterprise energy consumption and pollutant emission in Jilin province.
Taking data in Table.2 on behalf of the situation about energy consumption and pollutant emission of enterprise in Jilin Province, we take the above indicators as driving forces to do the corresponding scatter diagram as shown in Figure.1 to Figure.5.
That is to say, each index is higher; the energy consumption and pollutant emission is lower, and the better energy conservation and emission Table.1 Related data from 2005 to 2010 of industrial enterprise energy consumption and pollutant emission in Jilin province Item Year Energy consumption per unit industrial added value (tons of standard coal/ten thousand Yuan) Carbon dioxide emissions per unit value added (tons/ten thousand Yuan) Sulfur dioxide emissions per unit value added (tons/ten thousand Yuan) Effluent volume per unit value added (tons/ten thousand Yuan) Exhaust gas emissions per unit value added (million cubic meters/ten thousand Yuan) 2005 3.25 7.34 0.02 30.20 3.62 2006 2.80 6.77 0.02 23.70 3.23 2007 2.37 5.74 0.02 18.27 2.64 2008 1.98 5.10 0.01 14.27 2.29 2009 1.62 4.27 0.01 12.30 3.15 2010 1.62 3.48 0.01 9.84 2.10 Data source: statistical yearbook of Jilin province or calculated on the basis of statistical yearbook Table.2 Energy Consumption and Pollution
The marketization of energy conversation and emission reduction will give way to enterprises that actively promote energy conservation and emission reduction, which are much more able to benefit from it.

Thus, it is more effective to obtain a more realistic data mined from the vast amounts of geological measure data than other methods.
The prediction model established by it shown in Figure 1, is formed by the four sub-modules: data preprocessing, attribute reduction and rule generation and prediction.
Through data cleaning to smooth the geological drilling noisy data samples, and fill the vacancies value of the data sheet, remove isolated points [8].
It can be solved by smoothing methods or replaced noise data by the average data.
In this paper, using the probability distribution law to discrete a continuous multiple condition attribute, according to data distribution between the small segment to determine a threshold value ,and it is more than the discrete segment data value, then merge it with "near" range to, if more than the threshold will be divided into a class. 4 Attribute Reductions 4.1 Distinguish Matrices Attribute reduction directly related to the quality and efficiency of data mining is the core of the algorithm.

First, the data are refined by the data reduction technique, which makes it keep the data structure of the original data and have higher efficiency.
This procedure is called data reduction algorithm (DRA).
Let denote the original data set, denote the data set after reduction and denote the distance from data to data set of .
The fast speed of ERKPCM on three data sets owes to the data reduction technique, which makes it keep the data structure of the original data and have higher efficiency.
In the meanwhile ERKPCM has a high computational efficiency on most of the test data sets because the data size is decreased by the data reduction technique.

Noise reduction.
The noise reduction and ventilation cooling is contradictory each other for urban indoor substation.
The measurement data of before and after renovation demonstrated that this renovation on noise reduction and ventilation cooling has a visible effect in meeting the national standard for noise level of the substation surrounding as well as in improving the cooling effect significantly.
It can be also seen from the comparison data before and after renovation in Table 4, the installation of indoor sound-absorbing wall can reduce indoor noise about 5-6 dB, the soundproof walls and the air intake silencer can reduce the nose about 16-17 dB of noise, which meet the predict requirements for noise reduction.
