To implement such an analysis, energy data has to be related to the material flow states working, waiting and failed.
The needed energy data can be estimated or measured.
In the waiting state, the measured data showed a different pattern.
The corresponding data is illustrated in Table I.
Based on real measured energy data, the main energy consumers of the system were identified.

CO2 Emission Reduction Through a Sustainable Local Suppliers Network of Raw Materials.
Gian Paolo Marino1,a 1Politecnico di Torino, DAD - Department of Architecture and Design, Italy, +39 011 0908828 agianpaolo.marino@polito.it Keywords: CO2 emission reduction, Systemic design, Local potentialities, Sustainable logistic.
Furthermore, these benefits result in a higher quality of the entire supply-chain, in a significant decrease of logistics costs as well as in the consequent reduction of CO2 emissions [2].
In order to go through a project with the SD approach, it is essential to start from the current state of the art and to make a peculiar observation of all the aspects necessary for the system to live (energy and material input) and of what occurs inside it (qualities and quantities data).
Act locally: a) using local materials it is possible to obtain a greater traceability of the resources used in industrial processes so as to ensure, by implication, a high quality finished product; b) reduction of CO2 (actually its production is caused by a supply of raw materials and semi-finished products for packaging manufacturing which happens long away from the points of final packing); c) reduction in energy consumption due to unnecessary transport. 5.

And it is a data mining method that shows clearly and objectively the knowledge provided by reduction of the massive, complex data under the condition of keeping the classification property invariant.
Different projective direction reflect different data structural characteristics, optimum projective direction should be the projective direction which can reveal some eigenstrure of high - dimensional data probably.
Dispose data discretization, prepare the data, and generate the data processed discrete information table.
It is noteworthy that, for the application of RST, data processing is very important.

This distribution is an important input data for recrystallization models.
The recrystallization textures for polycrystalline copper rolled to low and high reductions were predicted in agreement with experimental results.
The used algorithm is a convenient method of function interpolation for irregularly scattered data, which is precisely the case, since we dispose of five stored energy values estimated independently for five ideal orientations (and equivalent ones given by the crystal and sample symmetries).
Stored energy values estimated from X-ray measurements for ideal orientations in copper rolled to 70% and 90% reduction [5].
Cross-sections of the interpolated SE distributions from preceding figure: (a) ideal orientations for copper; (b) SE for 70% rolling reduction; (c) SE for 90% rolling reduction.

According to the information of water quality, hydrology data and the discharge distribution of the river, we chose COD, ammonia nitrogen and volatile phenol as the main control factors, and some formulas were used to calculate the water environmental capacity of COD, ammonia nitrogen and volatile phenol.
According to monitoring data of water quality, among pollutants discharged into the river, the proportion of COD, NH3-N and volatile phenol is relatively larger, so we select them as evaluation factors of the water environmental capacity, the limit value of water environmental quality standards as Table Ⅱ{TTP}8545 .
According to comparison with data of Fenhe River, the results are relatively reasonable.
Hydrological parameters selection The water environmental capacity is different on different reaches or it has different flow, 1980—2008 series’ data is used in this paper.

It is obvious that the reduction starts from the exterior of the oxide crystals but the complete reduction could not be achieved.
Experimental data mentioned in the literature have also showed that the reduction rate increases when the amount of H2 rises from 5% up to 15%.
Further increase (up to 25%) does not influence significantly the reduction step [2].
Literature data confirm that the reduction rate of the wüstite is the biggest between 760-850ºC.
Being known the kinetic of the reduction the time and the temperature necessary to the complete reduction of the oxide layer could also be calculated.

Influence of Organic Load on Phosphorous Release and Absorption in HA-A/A-MCO Sludge Reduction Process Jinchao He1,a, Ning Zuo1, b 1Southwestern Science Research Institute of Water Transport Engineering, Chongqing Jiaotong University, Chongqing, 400016, China a401839655@qq.com, bzuoning_2424@126.com Keywords: Sludge Reduction, Phosphorous and Nitrogen Removal, Organic Load, Phosphorous Anaerobic Release, Phosphorous Aerobic Absortion.
Introduction In order to explore the method of improving phosphorous and nitrogen removal in sludge reduction technologies[1], an advanced process combining excess sludge reduction and phosphorous and nitrogen removal is developed, for short, HA-A/A-MCO process (Hydrolysis-Acidogenosis- Anaerobic/Anoxic- Multistep Continuous Oxic tank), which realizes phosphorous removal through hydrolysis acidification of raw sewage and phosphorus-release sludge improving phosphorus-release level and through eliminating anaerobic phosphorous accumulating sewage.
The researching results show that this process has better performance of simultaneous sludge reduction and phosphorous and nitrogen removal.
HA-A/A-MCO is an advanced sludge reduction process which is developed by our research group, whose flow path is shown in Fig.1.
When organic load is 0.141gCOD/gMLSS.d, 0.162gCOD/gMLSS.d and 0.207gCOD/gMLSS.d, the slopes of trio test data can basically coincide with that of regression straight line.

As part of this work the analysis of the impact relative rolling reduction at the connection area of bimetallic plate after the rolling process was carried out.
Bimetal plates Al99.8-M1E were rolled with relative rolling reduction e = 10%, 15% and 20%.
The microscope is connected to the computer on which is installed the NIS-Elements software for data acquisition and analysis.
The range of possible magnifications, along with fully automatic table provides not only to collect data from one area.
There was however observed, that the connection area after rolling shows a reduction of waviness.
