The following observations can be made from the Fig. 4: (1) From the curve plots in Fig. 4abcd, it is found that increased injection time in combination with other factors has a positive influence on reduction of sink mark depth and warpage; (2) It is observed that, form the curve plots Fig. 4cdef, with altering mold temperature, there were small changing on the value of sink mark depth and warpage. (3) It is found that, form the curve plots Fig. 4abef, increasing melt temperature in combination with other factors has a negative influence on reduction of sink mark depth and warpage.
The data of packing condition was (0, 80%; 6 , 80%; 11, 0).
The following conclusions can be drawn based on the experimental results. (1) The packing condition was the principal factor affecting the warpage and sink mark depth of injection-molded thermoplastic. (2) Increasing mold temperature and decreasing melt temperature has a positive influence on reduction of warpage and sink mark depth, there was minor contribution to minimizing warpage and sink mark depth by changing mold temperature.(3) An optimization packing condition was good for minimizing warpage and sink mark depth.

These allow a strong mass reduction which directly impacts CO2 emissions.
For instance, 50 kg of a car mass saving corresponds to a reduction of about 5 grams of CO2 each kilometer [7].
It is mainly used in aircraft, naval ships, spacecraft and missiles due to the fuel consumption reduction.
The model was implemented in SFTC Deform 3D environment; all the material data are available by literature and the room temperature (15°C) was imposed on the perimeter as boundary condition.
A quick data analysis suggests the use of Joule’s effect heating because of the significant power saving.

Using this principle, we can visualize the land-use type differences, the greater the bending of the curve indicates the greater of the distribution difference (concentrated), otherwise, indicating a more uniform distribution (dispersed).
3.1.2 Construction of the Lorenz curve based on energy saving
First step is to calculate the location entropy for all land-use types in Xinchang County through gathering the land use data of the entire county.
The data used in this study are based on the land use survey in 2005 and the second national land survey in 2009.
The main reason for this change is because of the substantial reduction of other agricultural land in some villages and townships. 4 Recommendations to Xinchang land use restructuring According to the principles of land scale effect, energy saving and carbon reduction, the land structure in Xinchang were basically in line with the law of land use.
From the energy-saving and carbon reduction targets, the village land should strictly be controlled in size.

All samples were heated up to the deformation temperature at a constant heating rate of 20 oC/s and soaked for 60 s, afterwards 60% of height reduction was conducted with a certain strain rate before the samples were quenched by air jet.
Assuming the test sample is a dissipator of power during deformation, the processing map of HCS/LCS laminated composite was constructed based on DMM by analysing the true stress-strain data.
Fig. 3(a) shows the PDM of HCS/LCS laminated composite after undergoing 60% of overall reduction.
Fig. 3(b) shows the FIM of HCS/LCS laminated composite after suffering 60% of overall reduction, in which the negative contour values profile the instability regions.
The Z parameter was calculated using the true stress-strain data.

The research objective of this paper is to present the result of past three years productivity data and discussed different results obtained after implementing the procedures of TPM in the sick textile industry.
From analysis of data taken during the past three years, the company has noted that it has not achieved the targeted productivity.
The methodology is based on analyzing the previous production data of manual and automatic production line.
This diagram simply consists of breakdown maintenance, poor plant layout poor resources & improper allocation of worker and past production data were taken in existing frame work.

Through technologies of thinning image and skeleton scaling, the size of embedded data is reduced.
The disadvantage is that the compression bit rate constraints the data volume embedded into watermark.
Accordingly we research image reduction little[6].
It compares the same information or data with P frame in front of it or I frame.
It concentrates the watermark image and reduces the size of embedded data.

In recent years, many researchers have concentrated on the influence of environmental conditions on structural modal frequencies based on monitoring data.
Other researchers who studied the relationship between modal parameters and environmental temperature based on monitoring data of CSB include Li et al. [4], Fan et al. [5] and so on.
However, this case enables us to grasp the limits of the change in frequency and can provide data for FE model updating.
In every trigger, 4096 response data points are collected, so the signal’s duration is 32s, which is enough for the response to die away to minimize the leakage.
For each recording, careful assessment of measured data and the resulting FRF must be undertaken, so as not to acquire poor data with the consequence of loss of quality in the modal parameters’ estimation.

It is easy for data collection.
Data Collection.
According to PAS2050, the data of the carbon calculation have two types: the activity level and the emission factor.
The activity level data refer to energy caused by activity of the product life cycle; the emission factor refers to the number of unit energy GHG gas emissions (such as CO2e/kwh, CO2e/ tCe, Ce/ tCe, etc.).
To buildings product, the data of fossil energy that is coal, oil and natural gas can be solved through the actual measure, and the data of land utilization can be solved through calculating carbon emission, then back calculating into standard coal consumption (this paper called virtual energy, assuming that the all CO2 from standard coal burn).
