This leads to the reduction at low frequencies and the increase at high frequencies.
The feasibility and accuracy of Tam and Auriault’s theory and MGBK method are assessed by experimental data. 2.
The above pictures show a systematic reduction in core length with increasing chevron inward bend angle in data sets (core breakdown initiation moves forward about 3D).
Conclusion Study of jet noise reduction on separated exhaust system using chevron nozzles are presented in this paper.
The comparison between prediction results and experiment data come to the conclusion that the far field noise spectra predicted by Tam and Auriault’s jet noise prediction theory and MGBK theory are within the acceptable accuracy.

The material properties of core
material shown in Table 2 have been taken from manufacturer's data.
The data shows a little initial rise in force with increasing impact energy before reaching a plateau and is independent of core thickness.
The trends in the maximum force data, Pmax in sandwich structures, Fig. 4, are similar to those of incipient load.
The residual strength data, normalized by the strength of the unimpacted sandwich panels, are plotted against impact energy in Fig. 8.
And the strength reduction behavior is influeced by thickness of core material.

The photocatalytic reduction of CO2 could be achieved over Cu/S-TiO2 under UV and visible light irradiation.
Consequently, photocatalytic reduction of CO2 over powdered catalysts is one of the most feasible methods to convert CO2 [6].
For photoelectrochemical reduction of CO2, the semiconductor anode under UV or visible light illumination produces electrons, which transfer through the external circuit to the metal cathode for the reduction of CO2 to hydrocarbons and alcohols, and holes that oxidize water to oxygen/protons [7].
All data of the reaction were taken at various times after turning on the UV light.
The effect of irradiation time on the gas products of CO2 photocatalytic reduction is shown in Fig. 5.

Keywords — Lean Supply Chain Management, Latex Industry, Cost Reduction
Abstract — The objective of this research is to reduce the total systemwide cost of the latex industry supply chain.
In general, a major lean manufacturing function is in the reduction of wastes.
An optimal operation, however, could mean an increase of apparent wastes in one part of the supply chain to allow for a larger reduction of wastes elsewhere.
Application of VSM in SCM not only can help identify VA and NVA activities for waste reduction and elimination, but it can also help recognize the status of the lead time and the total cost in the supply chain from incoming parts to the finished goods. 3.
Three main steps are involved in this research: Firstly the entire supply chain data are carefully collected and analyzed; these are used to create a supply chain model for the latex industry.

The size and number of carbide become smaller and lesser with decreasing the rolling reduction.
It is because of the reduction of dislocation density [2].
Stress-strain curves plain low carbon steel (a) cold-rolled to a reduction of 25%, 50% and 75%.
The data of the as-received (ferrite-pearlite) and the as-quenched (dual-phase ferrite-martensite) specimen are also shown, (b) cold-rolled to a various reduction and subsequently annealed at 500°C for 30 min.
The strength increased, but the elongation decreased with increasing the reduction. 3.

The
powder diffraction data were collected between 375 K and 975 K in steps of approximately 8 K/5
min. and evaluated by Rietveld refinements.
The powder diffraction data were collected at Beamline I711 of the MAX-II synchrotron in Lund, Sweden [3].
The samples were packed in 0.3 mm quartz capillaries, open in both ends, and kept spinning during the 5 min data accumulations [4].
Results The raw data (Fig. 1) of the CSS ZSM-5 directly show some important steps in the calcination and combustion processes.

) - Cutting, sliding, fatigue data Table 2.
To find a suitable Sugeno FIS which describes the selected data it is appropriate to divide the data into tuning and checking data.
There are two basic ways of dividing the data: - - dividing the area (which includes turning data) into smaller parts.

The drag reduction effect is declined.
The drag reduction is enhanced by increasing the contact angle.
This paper is going to combine microbubbles drag reduction technique and nonsmooth with hydrophobic surface drag reduction technique to improve the adhesion problems of microbubbles.
The interface play the drag reduction effect greatly.

The closer to the railway, the greater the reduction rate.
2.4 Analysis for the real-data of typical cross-section
After processing the real-data of the project, the central deformation of different sections of the line is demonstrated in Form 5, and the curve showing how the central vertical deformation of Line A and Line B vary with time is demonstrated in Fig 4.
Accordingly, the numerical simulated data and the real-data of these two processes for curve comparison.
Besides, the real data exceeds the simulated data by 1.9mm.
The simulated data are basically consistent with the simulated data, except for that of Line A, whose error rate is 20%.
The real data are generally consistent with the simulated data.
