A comparison between finite elements
calculations and experimental data has been carried out.
The good agreement between the experimental data and the numerical ones has demonstrated the possibility to obtain an optimized design of bonded patches with the numerical tools.
The measured experimental data has allowed also a comparison among different patch, adhesive and surface preparation properties.
This configuration could avoid the removal of the damaged component and in general could lead to a significant reduction of maintenance costs.
In particular the SIF was measured at the crack tip using strain-gauge data.

Thus, continuing reduction in the unit consumption of refractories has been steadily performed.
It was the switching over from bricks to monolithic refractories that gave the impetus for motivation and greatly contributed toward the reduction.
However, it can be said that, ironically, variable cost reduction according to imported raw materials/imported refractories has largely contributed to the outcome seen during around 1994 to 2002, when production was at a very low level.

In the rotor-bearing system fault diagnosis, the data mainly come from bearing vibration
monitoring.
At last, by means of the AD conversion of the acquisition instrument, these measured quantities are inputted into the data acquisition and process system (DASP).
Thus, noise reduction should be considered in the analysis processing.

The data used in the method include frequency before and after damage.
Their ideas are based on the fact that structural damage usually caused a reduction in structural stiffness which is accompanied by changes in vibration characteristics.
Commonly used modal data include the natural frequency and mode shape.

These data suggest that the pro-apoptotic effect of Bufotalin is mediated through activation of caspases and mitochondria in Hela cells.
The percents of cells in the late phase of apoptosis were 3.1, 6.7, 17.3 and 33.5% at concentrations of 0, 0.002, 0.004 and 0.006 μmol/ml, respectively (Fig .3).These data show a shift in the cell population from normal to apoptotic/necrotic stages induced by Bufotalin treatment.
Meanwhile reduction of the protein levels of procaspase-8,9 and the increase of their active cleaved forms were also detected.

The data allow the determination of the reversible volume for nucleation.
The reduction of magnetostatic energy due the magnetization reversal in a spherical cap with thickness x (Fig. 1) is directly proportional to the volume V of this cap [2].
This will lead to a law iHc µ 1/cos q, see Eq. (5), where E(x) and x are defined according Fig. 1: (5) The data also allow the determination of the reversible volume for nucleation.

The reaction mechanism was proposed based on experimental data analysis.
The noise resistance Rsn (f) was obtained by elimination of ECN data at the higher frequencies resulting in lower fmax values while maintaining fmin.
Results and discussion Noise data were analysed into the frequency domain using FFT algorithm and identified as the power spectral density.
Analysis of electrochemical noise data in the frequency domain of pyrite anodes in various leaching solutions gives three PSD plots presented in Fig. 1.
Electrochemical noise data calculated in the frequency domain for pyrite exposed to different medium at initial stage.

Civanlar et al. [5] considered one feeder pair at a time for loss reduction and derived a formula to estimate the loss reduction which would result from carrying out a particular switching option.
They have also developed the approximate power flow method to estimate the loss reduction.

In the first module, the beams, columns and slabs in the frame structure are modeled by the finite element software SAP2000, in which the model data are read into ABAQUS depending on the program written in this paper.
In the second module, the position, heated faces and duration of members suffering fire in the concrete frame can be specified according to the actual inspection data of members after fire.
In the pre-processing stage, a mass of original data should be inputted by the user that is to be read by calculation stage so as to calculate the mechanical properties of the concrete frame under different working conditions.
After the finite element calculation, plenty of data are produced, such as displacements, stresses and strains at the element nodes, etc.
