The actual energy usages were compared to loads of simulation data to verify simulation accuracy and real data and simulation result showed good match.
/h) 0.7 1 1.5 2 * bl : Blue layer, a: Air layer, cl : Opaque glass, ar : Argon gas, loe : Low-e glass Evaluations It was decreased by 20%~100% on east, west, and south directions, except for north, and the data was eventually compared following reduction of window-wall ratio.
There was no significant reduction in east direction.
This study analyzed a comparison data of heating and cooling energy per window composition and product specifications of ‘Hanglas’ was used as a standard. 6bl-6a-6bl as a basic model, 8bl-6a-8cl had the most reduction in cooling load, by 17.16%, and 6bl-12a-6loe had the greatest reduction in heating load, which was 9.38%.
Hence, it was found that reduction of window area was practical.

When reduction and reuse become difficult, recycling is desired.
Data Analysis Reliability Test The purpose of the reliability test is to prove the instrument is reliable.
Figure 1: Type of Projects According to Figure 1, the majority of respondent came from housing projects which contribute 47 percent of the data or 19 respondents.
Commercial projects came in second contributing 23 percent of the data or 9 respondents.

Selective Catalytic Reduction(SCR) technology is one of the best after-treatment technologies that diesels control NOx emissions and satisfy increasingly strict emission regulations [2].
Off-line matching calibration analyzes the engine running state and reference index recorded in the test process, afterwards calibrates every MAP diagram and finally updates new data to controller.
Online matching calibration directly modifies the MAP diagram data in Flash or RAM[3] while the controller is running to make the engine run in real time according to the new parameters.
Otherwise, adjust control parameter of MAP data until oxynitride density does not exceed the prescribed limits by either ESC or ETC.
The adjustment of MAP diagram data control parameters adopts the method of adjusting correction coefficient.

The convergence of experimental data and calculations is shown.
Analysis of the `equation system (1) shows that for its solution apart from reference data some individual values are necessary from experiments carried out expressly.
In particular data for the mass of welding bath are presented at Fig. 1 and described by relationship (2): ▲ – UONI 13/45; ● – UONI 13/55; ■ – MR-3 Fig. 1.
Comparison of calculated and experimental data shows their concordance.
The disagreement between calculations and experimental data averages 15%, which is comparable with the experiment error and is generally accepted for such models [1].

The thermodynamic data of the compounds in the article are from the literature[11].
The required initial temperature of the reduction reaction can be decreased to avoid the unfavourable influence on the nitridation process.
So it is necessary to select appropriate additives for the reduction reaction.
The mechanism of the effects of additives on the carbothermal reduction nitriding to synthesize the vanadium nitride is still unclear.

Our novel data evaluation technique was applied for data evaluation of the magnetic measurements.
This method is based on the multiphase-hyperbolic model of magnetization and it is called model based data evaluation (MBDE) technique.
The magnetic tester was controlled by a computer in which a 16 bit input-output data acquisition card accomplished the measurements.
This procedure is based on the multiphase hyperbolic model and it is called model based data evaluation (MBDE) technique.
The application of model based data evaluation technique (MBDA) was found to be a promising tool in data evaluation of magnetic measurements.

For petroleum industries, CO2 can cause corrosion, and heating-value reduction.
Therefore, the objective of this work is to measure the solubility data of CO2 in a 5M aqueous solution of 2-MAE as a promising solvent at the temperature from 30 °C to 80 °C and CO2 partial pressures ranging from 5 to 100 kPa.
Therefore, the objective of this work is to measure the solubility data of CO2 in a 5M aqueous solution of 2-MAE as a promising solvent at the temperature from 30 °C to 80 °C and CO2 partial pressures ranging from 5 to 100 kPa and to compare the results with those of aqueous solution of MEA.
Thus, the data from this equipment and procedure is reliable enough for the next experiments.

A standard generic car body known as Ahmed body is taken to set up simulation parameters in FLUENT by validating a test case against the experimental data available in literature.
A substantial reduction in drag force of 18.8% is achieved which can be attributed to lower frontal area and streamlined bodyworks design.
In this paper a 3D CFD study is performed on Ahmed body to validate simulation parameters based on reported experimental data [1].
The percentage of reduction in the drag coefficient is calculated to be 11.5%.
This leads to a compact and lightweight battery module with a weight reduction of 6 kgs or 10%.

(7) The least square method was used to fit the data obtained from plot of versus 1/T, and the activation energy E can be calculated from the slope of the fitted data.
The data corresponding to 1423~1473 K and 1573~1623 K were used to calculate the activation energy values of the initial and the final oxidation stages.
Conclusion Ultrafine powders of β-Sialon were synthesized by the combined sol-gel and microwave carbothermal reduction nitridation method and their oxidation mechanism was investigated.
