For example, a study conducted by Li[1] has applied wavelet transform to decomposition, noise reduction and reconstruction in a set of traffic flow time series collected from several detectors in signalized related intersections group.
Thus, situations occur where traffic arrives at the downstream randomly, contributing to the reduction of coordination control and adjacent intersection correlations.
The detailed field data collection efforts was performed on four adjacent intersections in the city of Chuzhou to collect data on signal timing, volumes of different movements, geometric properties and platoon characteristics.
Simulation Evaluation The field and simulation data were used along with guideline elements to determine where interconnection of a series of isolated signal is desired.
The field and simulation data collected were used to verify the guidelines established to evaluate whether signal interconnection is helpful in improving traffic operation through isolated intersections.

A characteristic capillary curve of the material pc=pc(Sl) is implemented as input data for the model. pc(Sl) is inferred from the experimental determination of the desorption-adsorption isotherms of the material [9] .
This fact will undoubtedly facilitate the transport of liquid in spite of the reduction in total porosity.
The numerical results are compared to the experimental data, as been shown in Fig.5.
As expected, the prediction of the weight loss kinetics by using the CA model is closer to experimental data compared to the NC case.
However, disparity still exists between the predictive profile and the experiment data.

The fault features reading from experimental data analysis are clear, accurate and intuitionistic, meantime, the validity and accuracy of WVD method proposed are nice from the experimental results.
As the data size of the experimental signal is very large, the envelope signal of the experimental signal is studied.
WVD of reduction of interference terms and noises Fig.3.
WVD of the experimental AE signal after picking out trend items In the course of AE testing, the data of AE signals usually deviate the baseline, so much so that the size of side-play amount will be also vary with time.
The whole course that data deviates baseline varying with time is called trend item of signals.

This numerical approach has been validated
through comparison between the calculation SIF results and available experimental data of a typical
test panel with a longitudinal crack.
These goals will be achieved by (i) significant reductions in airframe weight leading to lower fuel consumption and a decreased impact on the environment and (ii) improving efficiency by using new, high potential materials, design methods, manufacturing techniques and assembly processes on key primary airframe elements.
The boundary condition data transfer between different stage models are very complicated and time consuming.
The large mount of work must be done to make the accurate data transfer.
While presenting some of the experimental data, this paper primarily describes the development and application of substructure computational analysis techniques to determine stress intensity factors for the damaged panels subjected to fatigue pressure.

The experimental data was conducted under various excessive air coefficient conditions using an electronic ignition system developed self-dependently.
In-cylinder pressure data were acquired by a Kistler 6117BFD piezoelectric high pressure transducer which was integrated with the spark plug.
test engine specification Item Value Displacement volume 1.012L Compression ratio 8.8 Bore 65.5mm Stoke 74mm Rating power 39kW(5300r/min) Rating torque 78N.m were divided into two parts that in-cylinder pressure data were acquired and the emissions were measured.
In experiments of in-cylinder pressure data, the throttle opening was fixed at 20% and excessive air ratio Фa was kept at 1.1, 1.2, 1.3 and 1.4.
The increase of Фa results in the reduction of natural gas proportion in the combustion chamber.
