Therefore the data extraction form of vulnerability indicators in the light of density is convenient for regionalization and can be counted by the Yearbook in 2008.
For the data of subsidence rate, it can’t be counted in terms of administrative division, and in this paper a worst-case approach is adopted with assigning 3, 2 and1 to the regions, where the subsidence rate are 10~30mm/a, 5~10mm/a, and less than 5mm/a respectively, and the higher assigned value is more vulnerable.
(1) where ,and are the initial data, the normalization data and the first-item data of the ith sequence respectively.
Results and Discussion Setting the vulnerability indicator data sequences of each township as the comparison sequences, where, denotes the kth indicator; , denotes the ith township, and X is the set consisting of all township sequences.
Because the reference sequence is consisted of five smallest vulnerability indicator data, by which the aggregated land subsidence vulnerability degree must be the smallest whatever the used weight method and aggregation model are.

To test the system with high stability and reliability in the case of server or client problems of any party, farthest protected the existing test data, to ensure the examination continuing normally.
To get the data source through DataSource, DataSource object represented a physical data source connection factory, the main statement is shown as follows: Context ctx = new InitialContext (); DataSource ds = (DataSource) ctx.lookup ("TestDataSouce"); Added these codes into the setEntityContext of the entity Bean, the method would be invoked only once.
When using this statement, the data is passed to it, the statement is executed. 3.2 Regular expressions Regular expressions used a single string to describe and match a series of matches a string of syntactic rules, often used to retrieve and replace text that matches a pattern.
Advantage of Ajax technology is: it’s based on the standardized and widely supported technologies, no need to download plug-ins or applets; without refreshing the page, the user experience is very good; has a more rapid response capability; can reduce the burden on the server, Ajax principle is "on-demand access to data".
When using Ajax to send request to the server, returned the data to the client, if you want to display these data return to the Web, must use the DOM, DOM used the various commands to add content what you want to display in the html.

The data were collected by a 2D position sensitive detector for the sample-to-detector distance equal to 16 m and λ = 12.0 Å.
The collected data thus covered the scattering vector magnitude range suitable for a determination of particle sizes between approximately 150 Å and 2000 Å.
The results of the fit were not significantly sensitive to the shape of the modelled precipitates for the presented isotropic SANS data.
Measured (points) and fitted (solid lines) SANS data from thermally exposed EI698 VD nickel base superalloy at both temperatures.
Precipitates distribution models optimally corresponding to the measured data (least square fit) for differently exposed samples are displayed in Fig. 7.

Compared with experimental data, the relative error is less than 10% at t>b, the relative error is less than 5% at t>2b.
Mathematical modeling of variety of fouling resistance with time was developed based on experimental data.
The subscript cal and exp are represented as calculation and experimental data.
So the relative error of flux between experimental data and modeling calculating values is big.
At this stage, the error of flux between experimental data and modeling calculating values is small within 10%.

The selected features will be used as an input data to KNN or C-KNN classifier.
Each group will consist of random number of data which is relatively close to each other.
Each subclass will be represented by one or more data depending on the number of subclasses.
Then, the classification algorithm based on the nearest neighbors will be used to classify the representative data.
