The data recorded on the 7th channel is processed with Hilbert transform, and the result is shown in lower panel of Fig. 2.
Because the block processing is executed on the beam output waveform, the data P(1) after 50s cannot be acquired.
While in Fig. 4(c), the second principal component data P(2) is obtained, which is obviously different from the data P(1).
The data P(2) contains the information of acoustic field aberration caused by the intruder, which is not existed on the absent of the object.
The proposed method needs further verification with the sea trial data.

This data was later logged in to the National Instrument software via data acquisition (DAQ) card NI-6009.
The data gained from the experiment will be compared to the calculated data from the simulation.
The data were logged using National Instrument NI-DAQmx software and NI6009 DAQ.
In general, the simulation result and the experimental data had similar trend and close value.
However, there are still gaps between the data that could be corrected by a correction factor.

The library of thermodynamic data contains data for both reaction products and reactants.
All data in this library are for species in their standard state at a specified temperature.
Thermodynamic data for many individual species can be conveniently stored, for use with computer programs, in the form of coefficients associated with equations that reproduce the data as described below: cp0rr=a1T-2+a2T-1+a3+a4T+a5T2+a6T3+a7T4 (1) H0(T)RT=-a1T-2+a2LnTT+a3+a4T2+a5T23+a6T34+a7T45+b1T (2) S0R=-a1T-22-a2T-1+a3LnT+a4T+a5T22 +a6T33+a7T44+b2 (3) Note that b1 and b2 are integration constants.
In addition, the authors have entered these newly generated data into the CEA software for the first time, making possible the theoretical calculation of palm oil combustion by CEA.
Crude Palm Oil (CPO) Combustion Analyses by CEA CEA calculates the combustion of elements and compounds using the initial data and by determining the type of analysis that is needed to proceed.

It also can solving definite integral value, undertake integral curve, data point curve fitting (empirical formula), etc.
For the measured the area of the graphics, measurement, before the actual graphic data compression in the range domain, without the permission of the values measured area, with A two-dimensional hausdorff measure formula[4] (,is scaling ) was carried out on the actual data reduction, to get the value of the area of the measured graphics.
By two variables, several groups of experimental data to find out the function relation between the two variables or function curve (empirical formula), the commonly used method is to set the function first, and then through the method of curve fitting approximating function, that is, from the arrangement of data points is to determine the function type, containing function expression of the undetermined parameter Settings, reoccupy and undetermined parameter approximation method, experience formula.
The experimental data is set a variable , with,, .
Using dynamic measurement methods, we give concrete method of integral curve, curve interpolation function approximation of the measured data point to solve the problem.

Then the data that were obtained through the experiment were analyzed.
First of all the strain gauges are affixed on the points of the front axle housing that need to test, and then the stress-strain data of the each measuring point is read after the data is processed through the compute and the strain gauge.
In the experiment, a data collection box is used, while the large amounts of data are collected through computer software to reduce the workload and make the data have higher reliability.
In this experiment, the times of loading as 90kN are three times and the experiment data are shown in Table 1.
The results showed that the test data of the experiment is larger than the data of the computer simulation, and some parts of the difference are relatively large.

Spectral images contain a large volume of data and the development of multispectral imaging systems places considerable demands on computer hardware and software compared with standard three-component or trichromatic image storage and processing.
Introduction Spectral images contain a huge volume of data and the development of multispectral imaging systems places considerable demands on computer hardware and software compared with standard three-component or trichromatic image storage and processing.
Many studies [5,6] have been done to study the number of basis functions required for low-dimensional linear models, which are all derived from the spectra data sets themselves, and few works are concerned with human visual system expect one previous work using human L, M, S cone fundamentals to get the first three components Lum(l), rg(l), by(l), which represents one luminance and two chromatic channel respectively [7].
When comparing the results in Table 1 which contains reconstruction errors for the same group of images using both proposed representation method and conventional linear model, it can be found that when only 3 basis functions are used, the spectral reflectance reconstructed by conventional linear modelling presents much smaller reconstruction errors spectrally than the spectral reflectance reconstructed by linear modelling with the first three basis functions derived from color matching functions, but the color difference DE*ab is not necessarily smaller, and it is dependent on the image data sets.
While by using the conventional linear model, where the basis functions are derived directly from the data set its own, mathematically, the spectral fitting should be the best, but it may create spectra that has relative large error at the spectrum where human eyes are very sensitive, and therefore presents large reconstruction error in color difference.

The collection of the data of the existing production line was conducted at one of the automotive company in Malaysia.
The data required in the analysis are the customer demand per day, the available working time per day, the number of manpower used, the number of workstations includes and the dimension of all workstations.
By using this data, the cycle time, takt time, minimum number of workstation and efficiency were calculated.
Results and Discussions According to the data provided by the company, the customer demand per day is 16 units.
Based on the data collected which is the cycle time from each workstations on the Trim line, the cycle time on each workstations are shown in the Table 1 and can be visualize using Yamazumi in Figure 1.

Furthermore, the scatter in the data of Glunz et al. has been much larger, making these results less reliable.
After TD formation, they measured a pronounced reduction in the metastable defect concentration by up to a factor of 3, giving an indirect confirmation of the proposed dimer model.
