Joints between dissimilar metals are commonly used for the purpose of tailoring component properties or for weight reduction.
To obtain the data of the temperature distributions of the weldment, thermal analyses were performed during a complete cooling to ambient temperature.
The analyzed data show that the measured temperatures are biased to the right side, and that the peak temperature is higher because of a more elongated pulse duration reading through the average power, as shown in Fig. 4(c).
A pulse heat input model was developed to avoid numerical convergence problems due to the instantaneous increase in temperature near the MPZ, however, most of the analyzed temperatures are very similar to those from the experimental data.
In this study, the predicted melt-pool zone shapes and residual stresses considering various gap widths were found to be in close agreement with the experimental data.

The most important task in model updating is the determination of the changes to be made to the numerical model and hence, maximise the correlation between the numerical and experimental data.
The box was excited with an instrumented hammer, as recommended in BS 6897 [11] and the vibration data of the excited structure were acquired via a portable digital laser vibrometer (PDV 100) focused on strategic points on the structure.
Correlation of Results The data for the correlation analysis are the natural frequencies of the box obtained from the excitation response test and the finite element analysis.
The vibration was generated by the energy input into the structure using an instrumented hammer and the vibration data picked by the use of a laser vibrometer.

The absolute values of oxygen content in air, used as reference for the coulometric titration data, were obtained by thermogravimetry (Setaram TG92) employing reduction in a dried 95%He-5%H2 gas flow.

Equation (1) adequately describes experimental data, as illustrated by solid lines in Fig.1, and was hence used to evaluate the partial conductivities.
The data on ion conductivity at reduced oxygen pressures are shown in Fig.2.
Similar conclusion was drawn from the Mössbauer spectroscopy data, which will be summarized in a separate paper.

If a more accurate DAF can be obtained, then possible reduction in highway bridge maintenance/construction costs may ensue.
This method is probably more convenient than others of modal testing because test can be carried out while the structure is under service loading and the increasing availability of robust data acquisition and storage systems [[] Demeke B.
Ambient vibration testing implicitly assumes response data alone could be used to estimate vibration parameters [[] Williams, C.
Based on the formula of Eq. 1, DAF is computed from recorded data.
If the DAF is to be computed with measured stress data, the obtained results will be more deviation. 3) Vehicle speed is an important parameter influencing the DAF value.

According to the dry density and other data of mixed soil , according to formula (1), the porosity of mixed soil under the same compaction degree condition in the state of maximum dry density has been calculated, as shown in table 3
In addition, if the specimen placed into 90 days later under natural conditions, its thermal conductivity has a certain degree of reduction.
Through the test data it can be seen that the shear strength of rammed earth is obviously improved than simple soil and sand mixture after adding a certain amount of additive lime, but no longer increases and even has a downward trend when the hydrated lime content increased to 15%.
Through analyzing experimental data, the following conclusions can be drawn: In the case of thermal properties, when the mix proportion of hydrated lime in 15% , the thermal conductivity and thermal diffusivity of rammed earth was maximum.
In addition, the strength of rammed earth is affected by various factors, the maximum dry density and optimum moisture content of mixed rammed earth may be rapidly tested according to the site conditions, through the test data the moisture content will be controlled and the appropriate additive content was determined in order to provide a strong basis for rammed earth building construction[2].

This shows further reduction of element size beyond 5 mm can be omitted and 5mm element size is considered for mesh settings.
Firstly, the shaft is preassembled with a strain gage rosettes that provide shear strain data.
The data were acquired using a LabVIEW programme.
The analog voltage signals from the strain gauge module are then sent to a NI PCI-6056E data acquisition board (DAQ) in the notebook where it acts to convert the analog signal to a digital signal.
All of the data files were recorded in LabVIEW and the experimental results of the measured shear stress of the shaft are collected and plotted.

The world average productivity of all types of land adopts the statistical data from the United Nations food and agricultural organization [11].
The data of the electricity consumption, natural gas consumption, water consumption, food consumption and waste discards came directly from logistic management office and the Energy Saving Office of XAUAT.
The data of transportation was obtained indirectly from the questionnaires while the components of waste were from sampling and analysis in garbage station.

Vibration reduction should be achieved by the installation of special anti-vibration mats on the travel layer of the bridge.
For the seismic data processing, including frequency analysis, the programme Swiproject (Vistec) is used.
Evaluation of measured data Measured vibration transmitted through the bridge to the ground is the speed of a mass point oscillation.
When comparing the data analysis during the entrance and the exit, there are some obvious differences in the values of the maximum velocity amplitude of oscillation.
The entire data set was evaluated just in the field of amplitude and will require a more detailed analysis in the frequency field.
