The strain gauges, load cells and LVDTs were connected to the same data logger and the results recorded automatically at each load step.
Comparison of predictions of formula with experimental data.
The figures show that not only the predicted failure modes of prestressed beams are well agree with the actual failure modes, but also the predicted nominal moments are very close to the experimental data.
Because the experimental data is very limited and experimental beams are all over-reinforced prestressed sections, the equations of ideally reinforced section are not confirmed.
(e) The predicted nominal moments are very close to the experimental data.

Annual average daily traffic (AADT) serves the important basic data in transportation sector.
Introduction Traffic volume is used as basic data for road and transportation planning, design and policymaking.
Short count is carried out in all roads estimated to require traffic volume data.
The results of analysis on traffic patterns for 365 days through the permanent count data showed that there are daily and monthly patterns in traffic data.
However, since there was less change in weekday traffic data, the short count is conducted on weekdays.

HUANG Yuanxiong HUANG [5] further simplified the method and put it contrasted with the monitoring data, finding it matches well.
Therefore the pile length reduction factor can be defined as Eq. 2.
There were few field monitoring data of bottom upheaval because of the difficulty of monitor.
Therefore, the upheaval of lattice column was referred as field monitoring data.
(3) The study of Shanghai Natural History Museum foundation pit showed that the bottom upheaval calculated by the correction method was more close to the monitoring data comparing with the upheaval calculated by method of residual stress.

The data tier comprised of social composition data, economic data, water resource data, eco-environmental data etc., and they are divided into two major categories - parameter and variable.
These data will be collated and transmitted to the constraint tier and objective tier.
There are mainly 74 input data and 44 output data in the model.
The flow data from 1956 to 2005 reflect that of long term average flow and the data from 1980 to 2005 reflect the conditions of relatively low flow in recent years.
Our future work will focus on strengthening the use of remote sensing of ET data.

But LPP cannot be achieved owing to singularity of matrices while the face training samples is deficient and face image data dimension is high.
It combines MMMC with 2DLPP algorithm and constructs a parameter for more optimization. 2DLDPP can further get data in between-class distance more close and in within-class distance more far.
Because MMMC can map the data into an optimal subspace for classification [22], the discriminability of the data will be improved greatly.

As a result, it is possible to improve significantly the metal structure at the same values of the forge reduction.
It is shown that the accumulated degree of shear deformation, as well as the uniformity of its distribution, is higher for the new method with the same reduction values.
The reduction per pass was equal to 0.21, where h0 and h1 are the initial and final height of the billet.
This circumstance must be taken into account when developing the technological process by calculating the metal damage ω by the formula where a and Λr are the empirical data of the materials, Λ is the measurement data of the accumulated degree of shear deformation from computer or mathematical simulation [21].

Because the dynamic soft reduction of continuous casting process is based on the computation of the solidification end point, using model to simulating the steel solidificating process is more and more interesting.
Using model to simulating the steel solidification process is more and more interesting, as the dynamic soft reduction of continuous casting process is based on the computation of the solidification end point [4-7].
The input data for the model is listed in table3.

Processing We may get standardization of indicators according to standardize the original data matrices.
We adopt the basic data of the cities and standardize them to establish the characteristic matrix.Using the Eq.1~Eq.3, we can get the entropy and the information utility value , and use Eq.5 to work out each indicator’s weight .
