Statistical data has indicated that a large proportion of road traffic accidents occurred at signalized intersections in Japan, around 20% based on the data in 2003 (ITARDA, 2003).
The video data will be collected from which the driver behavior parameters deemed essential for this study will be extracted.

In order to meet the demand on the miniaturization and manufacturing cost reduction of
the multilayer ceramic capacitors we have developed a nano-BaTiO3-based non-reducible dielectric
material through a soft chemical route.
It is 30 nm for the powder calcined at 850℃ for 2h.The XRD data of the ceramics of nonreducible BaTiO3-based dielectric obtained after 1200°C sintering show that the diffraction peaks become much sharper.

Reduction in adhesive remnant is
likely due to the higher bonding of adhesive resin to granules.
The Weibull statistics were useful to relate survival in clinical trials to the data obtained from laboratory tests[5, 6, 7].

Conclusion
Using return mapping algorithm of von Mises model to make the nonlinear finite element program can be a good numerical simulation, the calculation results and the analytical results are very closed.
In order to simulate the plastic zone, a certain percentage reduction of the parameters, making the horizontal displacement and the stress of the numerical calculation is too large.
In this paper inversion of this program is verify the availability of back analysis procedures, but apply it to practical, inversion results largely depending on the accuracy of on-site monitoring measured data are reliable.

The structure parameters of the series R3Ni2B2N3-d summarized in Table 1 reveal a volume reduction which tends to follow the lanthanide contraction, however, with a significantly larger contraction in the case of Ce3Ni2B2N3-d which is attributed to intermediate valence of Ce-ions, where cerium adopts a smaller ionic radius than that expected for Ce3+.
The zero-field resistivity data displayed in Fig. 3a reveal normal conducting metallic behaviour for both compounds.
The resistivity of Nd3Ni2B2N3-d exhibits a sharp kink near 20 K which indicates a magnetic phase transition, whereas the Pr3Ni2B2N3-d data do not exhibit any anomalies.
In case of Pr3Ni2B2N3-d temperature dependent susceptibility, isothermal magnetisation, and specific heat data in Fig. 3b, Fig. 4b and 4d, respectively, do not reveal any indication for intrinsic long range magnetic order at least down to 2 K.

The reduction of one logistics activity cost may cause increase of the other logistics activity cost because of the tradeoff.
Input data, simulate transportation system costs change, analyse the data and give policy advice.
Due to the limit of the paper length, this paper didn’t input data to the model and gave the availability test.

After the wind farm constructed and operated, we should pay attention to that the utilization rate of the wind energy must be influenced by the reduction of wind speed.

Fig.3 Capacity factor and the percentage of capacity factor decreased According to the above theory and the data from table 1 show that in a certain year the wind speed distribution is constant, so the annual average wind power density has a given value.

The basic idea of ERA method is based on the impulse response data of the system.
The basic idea of the method is that we use the free response (displacement, velocity, acceleration of any of the three)in each measured point, and through three different delay sampling, we can structure of free response sampling augmented data matrix, and establish characteristics formula according to the mathematical mode of free response, then we can solve it and estimate mode parameters of each order.
The layout of measuring points is selected record time-history response data node, as shown in figure 4.
