The results can provide some basic data for the mitigation of environment vibration arising from traffic loads.
Compared with the traditional methods, it has advantages of a reduction in the height of the main girders, the saving volume of work, the lithe outward appearance and the high degree of safety, but also there is a limitation in construction costs [2].
Test Analysis For the cases listed in Table 1, a bulk of the data were measured.
Considering the length of this paper, only partial and represented measured data are selected to analyze and discuss in the following sections.
The vertical, radial horizontal and tangential horizontal acceleration response data of each measuring point of ground for case 6 is taken as the example.

SPT results have also been accompanied by fractography, fracture energy calculations along with comparisons with uniaxial data.
This does not clearly present itself within the cast data.
Collation of SPT load-displacement data for all material variants and displacement rates.
Comparison of uniaxial data with SPT results, along with effective UTS figures.
This complements findings discovered in the load-displacement data and the fractographic analysis.

The
ANNs were trained with a percentage of the data collected, selected at random, and assessed with
the remaining data.
All data were normalised before being presented to the ANNs, to ensure that the data lay in the range [-1, 1].
The remaining data were used to assess the ANNs.
Results The trained ANNs were presented with data they had not previously seen to test their ability to deal with new data, and also presented with the same previously unseen data to which artificial noise had been added, to simulate experimental data.
The reduction in accuracy of prediction was only slightly degraded when up to 15% error noisy data was added to true values and predictions re-analysed.

The material constants were based on previous experimental data conducted on the same material.
The material model behaviour was fitted to previous experimental data obtained on the same material.
The comparison between the numerical results and experimental data appears to be in good agreement.

The experimental data fitted very well the pseudo second order in kinetic model for both activated carbon where the adsorption controlled by chemisorptions.
According to data reported by the Ministry of Agricultural and Agro- Based Industry Malaysia, the annual production of jackfruit in 2011 was projected at 56,631 MT, translating to approximately 33,979 MT of jackfruit peel as by products [7].
The linear forms of two equations (Langmuir and Freundlich isotherms) were applied to fit the equilibrium data as they were commonly used by most of the researchers.
Based on the experimental data, JPAC correlated reasonably well with Freundlich isotherm whereas Langmuir isotherm well fitted with the equilibrium data for adsorption of CAC.

In [2] proposed a method for data hiding by exploiting the IPCM encoded macroblocks during the intra predication stage to hide the desired data.
In addition, the head data of the video is very essential, therefore, select the head data as the carrier can also improve the security of our algorithm.
Namely, the proportion of coded residual data in the MB becomes low, and in contrast, the proportion of head data in the MB becomes high.
Slice syntax can be seen as fig.3 Figure 4 Mapping rules A macroblock can be divided into two parts: the head data and the coded residual data.
And in our method, we embed data by modifying the head data, which will have influence on the number of the MV only.

The TGA data showed that the material obtained as the end product of the experiment was free from any impurity.
This data is supported by the fact that nanotubes heated in argon environment showed no change in weight up to 1000⁰C indicating that no oxidation and consequent weight change was seen [19].
Thus, SEM and TEM data are in accordance with TGA data which indicates significant reduction in both carbonaceous and catalyst seed impurities.
It is observed that the nanotubes suffer some damage during the oxidation and removal of catalyst impurity, resulting in the reduction of GD ratio.
Data from different evaluation techniques imposed on the treated SWCNT showed that the process yielded highly pure SWCNT in comparison with the pristine SWCNT.

In order to develop and promote ISWM, it is required to compile a comprehensive data on present and anticipated waste situations, supportive policy frameworks, knowledge and capacity [3] .
Many large power producers in industrialized countries are looking to biomass as a means of meeting greenhouse gas reduction targets.
This data promote the utilization of waste biomass globally.
DTA curve, on the other hand, provides data on the transformations that have occurred, such as crystallization, melting, glass transitions, and sublimation.
Obtaining comprehensive data on chemical and physical structure and properties of agricultural waste is vital for evaluating their capability for specified application and also for finding proper treatment for enhancing their efficiency.

They are in agreement with literature data [4,17] and fit power laws of
the type t = Aσ
1/n and dε/dt = B σ
m
respectively.
The data at 1000°C fit a power law.
This result is consistent with literature data [4,14] and indicates that the composite can avoid the matrix crack propagation produced in the first loading cycle, in fact the microcracking process is arrested during cyclic loading and remains stationary because the fibre bridging in the crack wake reduce stress intensity at the crack tip.
The reduction of the tangent modulus and the strain ratchetting can be related to creep damage, as it has been found by several authors [4, 12].
The data are in good agreement with literature values obtained on similar materials.

And although a delamination reduction seems to occur in cryogenic drilling, there is still no clear identification of parameters, types of drill bits and even the temperature to be reached [15].
This method allows determining a density function when the data do not necessarily fit a known distribution and its expression can be seen in Eq. (2), where n is the number of observations, h is the smoothing bandwidth, Xi is the value of each observation, K is the Kernel function.
For these statistical analyzes, Kernel density estimation and non-parametric Kolmogorov-Smirnov test, Statgraphics software [20] was used to conduce the data.
This is inconsistent with Safri et al. [1] that found that a high density in a fiberglass reinforced composite favors a low delamination, but is consistent with other data found in the literature [5, 6].
In Fig. 3 (Fig. 3.a for DFi and Fig. 3.b for DFo) can be seen that the diameters data does not fit a normal distribution, in particular those corresponding to PA66-GF30.
