This lock-in technique improves the signal-to-noise ratio, making extracting meaningful data from the noisy environment easier.
These data are obtained by fixing the diode current to 200 nA for all the different temperatures.
The data of panel (a) are averaged over 20 measurements at each temperature.
Data are taken at 500 °C.
The high-temperature data are based on work supported by the Defense Advanced Research Projects Agency (DARPA) under Agreement No.

The viscosity index is mostly over than 200, the test data in the table, except the viscosity index value of the coconut oil is 107, and the values of the remaining vegetable oil are from 195 to 244.
These data suggest that the vegetable oil has excellent viscosity-temperature characteristics.

With practical data of the BF ironmaking from Jiuquan Iron&Steel Cooperation Ltd.
Among the three main processes-blast furnace-converter (BF-BOF), direct reduction-electric arc furnace and scrap steel-electric arc furnace, BF-BOF occupies the dominant degree [1].
Data collecting and pre-processing In this paper, the whole continuous data (one group data is recorded once an hour) in two days were collected from BF system of Jiuquan Iron&Steel Cooperation, and the output and input parameter data heading is respectively shown in Table 1.
After multiple correlation investigation of independent variable aggregation (only part of correlation data is list), altitudinal multiple correlation phenomenon of X can be seen and so multiple regression model has bad reliability.
The regression model was set up by partial least square regression method with practical data from BF system; the calculation and analysis process is shown as below.

The output voltage and current is recorded.The data is fit according to certain fitting algorithm and IU characteristic curve can be obtained.
Although the method is able to reflect the output characteristics of a solar cell accurately, we need test plenty of data if more than two curves are need in which case the cost and the test period increases.
The output characteristics of solar cells can be obtained according to the basic data from the manufacturers.
At the same temperature and light intensity, measure and record the value of output voltage and current,analyze and compare with the simulation results.The simulation results and the test data are shown in Fig.3.The results shows that: the error of simulation and test data results is 1% or less, and meet the design requirements; the model can meet the actual analysis of the solar cell output.
Fig.3 Tthe error of output data Conclusion This paper proposes a practical mathematical model of solar cells in connection with the complex mathematical model and low precision according to the national standards.

The experimental data have shown that the engine’s temperature has an influence on CO2, CO, HC emissions.
To report data determined in laboratory tests for a precise analysis or in research workshops obtained under arbitrary conditions of temperature and pressure requires the adjustment to the standard conditions..
The BEA Emission Analyser - Bosch The data resulted after the 18 tests were downloaded and a database was created in order to analyze them.
The results of collected data (excess air factor λ, CO, CO2, HC and O2 concentration) are shown in Table 1, Table 2 and Table 3 [6].
Results and discussion The centralized data were used to determine the dependence between the exhaust gas temperature and concentrations of three compounds: CO, HC and CO2.

By means of factor analysis and logistic regression approaches, this paper predicted financial failures of Chinese listed companis in 2009 from the published data in 2006 of those companies.
But most of these financial risk analysis are based on accounting data and financial ratios.
Sample and Data Selection.
Then the financial failure analysis was based on those data of 2006 fiscal year, in order to achieve the purpose of prediction, i.e., risk analysis and control beforehands.
In rotating the factor loading matrix after extracting factor, and its economic significance to clear explanations, which not only can find out the influence of a company's financial condition main factors, but also for warning model dimension reduction processing, to simplify the regression model.

The fouling of the coil leads to poor airflow, reduction of heat transfer efficiency coupled with high energy use.
It starts with an actuator, regulating the height of the distribution nozzle in relation to proximity sensor data.
This is a huge reduction of 122 liters per operation, which indeed shows that the new system has outstanding efficiency in the use of water.
This reduction in manpower complements the overall reduction of labor costs and improves general operational efficiency.
Data in the graph indicates that the new method drastically cuts down the time required to perform the full cleaning operation, performing it within 13-16 minutes.
