The pre-processor of the DEFORM software is designed to assist users in preparing and verifying input data during the forming analysis.
The compression force at each step reduction were extracted from the DEFORM software.
The flow stress was determined as a result of the potential fitting of the data obtained using the Grapher 3 software.

Under current situation, with high labor cost and energy cost having an impact on production cost, the need for cost reduction in the industry is extremely of concern.
This research demonstrates application of the lean supply chain for cost reduction in the industry.
Methodology Four main steps are involved in this research: First, a study on the current state of the rubber glove supply chain using data collected in southern Thailand - logistics cost is classified in this step; Second, identification of NVA activities with the purpose of reducing the wastes in the supply chain, NVA activities with higher logistics cost are chosen for further analysis; Third, analysis of the causes of NVA operations and investigation of countermeasures against them; Fourth and final, proposal of practical guidelines to reduce those wastes. 3.
Based on data collected in this study, VSM of rubber glove supply chain is developed in Figure 3.

The paper proposes a global backlight dimming algorithm for CR enhancement and power reduction.
The BLU dimming will lead to image brightness reduction if the pixel grays are not compensated.
To reflect both the image brightness and CR, 2 data are got from the histogram: H25 and H75, which means the gray level including the 25% and 75% area of the image histogram, respectively.
The data in Table 1 clearly show that the proposed dimming algorithm reach average 34.95% CR improvement and 11.30% power consumption reduction.
Let’s take a deep look at the simulation result data in the table 1.

New information is ultimately mined from “Data Sea” filed up in existed structures.
So much important information are hided behind the surging data , people hope to do the analysis of higher layer, for the purpose of better utilization on these data.
The current database system can efficiently carry out the function of data entry, searching and calculation.
However, it can't discover the existent relation and the rule in the data and can't predict the future development trend according to the existing data.
Lack of the methods of excavation knowledge the data concealed, cause the phenomenon of” the data explosion and the knowledge lackage".These systems have already constructed huge"data mountain" on the scene currently.
