This technology has the advantages compared to conventional manufacturing via stamping and welding, such as reduction in work piece cost, tool cost and product weight [1].However the success of the THF process is dependent on the loading paths, internal pressure versus time and axial material feed versus time.
The advantage of uniform design method is significant reduction of the test amount in experiment design, and the factors of test have a good uniformity and can better reflect the influence law of various factors on objective[6].
The sample data was substituted in formula of the response surface model, the value of the objective function was calculated.
The integration between the utilized techniques and the FEM simulations of the investigated process could obtain the necessary data with a low computational effort.

Discussion and Data Analysis Electric Energy analysis.
Fig. 8: Void comparison in over-pressure reflows Conclusion This paper discussed the trade-off between the electric energy consumption, process lead-time, voids creation in the solder joints, and the cost reduction as the result of energy consumption reduction for the soldering process.

Measurements vehicle performance data comprised brake power (kW),flywheel torque (Nm), fuel consumption rate (kg/hr) together with the exhaust emissions like hydrocarbon (HC), oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx) and smoke opacity by using autocheck 5 channel gas emission analyzer and danger MSI.
Further analysis and presentation of data is based on the average of measurement.
The reduction of smoke emission may attributed to its oxygen content and small particle diameter of the injected fuel at a high injection pressure, thus more oxygen content will produce more NOx, then decrease the smoke emission while increase the CO emission when engine speed increases.
The summary as follows: 1 The engine performance doesn't vary significantly with the changes of the CPO blending ratio for all load conditions. 2 The engine emissions promote the reduction of HC and CO in the range 10% to 15% of blends due to more oxygen present during combustion, thus the combustion will become more complete and in oxygenated fuel.

These data are approximate to a considerable degree, since at almost all the stages of calculation the authors had to use averaging and assumptions related to peculiar design features.

(3) Distinguish ability: the sample data of each index should have obvious difference
(3) Where RQD is quality designation, Jn is the joint number, Jr is the joint roughness, Jw is the joint reduction coefficient of water, Ja is the metamorphic degree of the joint, SRF is the stress reduction coefficient of water.
The grey model (GM) were established in three steps, on this basis, the new information model GM (1, 1) was got by reducing or increasing new array data, with higher prediction accuracy[5].

A validation survey was carried out and the data collected was analysed using SPSS in order to confirm the significance of retrofitting Universiti Teknologi Malaysia (UTM) buildings toward green building initiative.
Besides, available energy efficient and renewable energy technologies can also contribute to a reduction in the energy use in high-energy use office buildings.
The second phase was studied the design concept and procedure used in GBI- NRED and then identify all the data or input needed for questionnaire preparation.
The data collected from the questionnaire paper was analysed using frequency method and the finding was discussed in conclusion, limitation and recommendation on further retrofitting in UTM campus.

The solution to the problem is put forward and the direction of the noise reduction measures in the future is pointed out .
Analysis of results The result based on the vibro-acoustic effect shows good consistency with the measured data, and it can be obviously seen that ignoring the vibro-acoustic effect can cause great difference from actual results.

It is commonly recognized that success of the products innovation depends on the reduction of product life cycle.
Five single measured lengths were used as Max–rule to evaluate roughness data by ISO 4288.
On the other hand, measured roughness data often showed lack of statistical normality.
In order to eliminate that effect, the so called Box−Cox power transformation with the optimum lambda λ has been used for the measured data as solution in MiniTab software.
Basic comparison of the milling strategies results from effect of the side step ae whereas the range of the measured data are shown in the Table 1.
