Data for concrete production were obtained specifically for this study in a Portuguese industrial facility and are registered in Table 1.
As the data for the background processes and for internal transport and electricity used in the industrial facility was not available, the analysis was carried out with data from Ecoinvent database [12].
If the scope, assumptions, data quality, scenarios or LCIA method chosen varies from one study to the other, the LCA results will be different.
In this phase of the material characterization, one can state that the concrete with fly ash incorporated may be classified as an eco-material (eco-concrete) considering that the environmental issues that are minimized are waste reduction, reduce of landfill problems and resource saving by the utilization of recycled materials.

Introduction The optimization problem of load distribution in the finishing-mill rolling process is how to get a serious of data about the slab thickness hi; and the data will make the whole system state most optimal.
In general, the rolling schedule is a chart full of experiential data which people get from the load distribution of actual production[1].
The data relying on this method is reasonable, but not optimal.
Simulation We combined 470 rolling data to establish and 16 data to check up the predict thickness model.
So once checking data outputs, the model usually educes unreasonable error.

Data driven techniques have been applied in many chemical processes.
This paper is used PCA and FDA to produce a lower-dimensionality, PCA is a dimensionality reduction technique which transforms correlated original multivariate data to a set of uncorrelated data [14].
Sampling time was used to collect the simulated data for the training and testing data is 3 minutes.
Let the original data set, where each row is a single sample of data set and each column is an observation.
Reduction order A reduced set of a smaller number ‘a’ (adata are good for fault detecting.

Particulate organic matters reduction of TADP was superior to that of MADP.
bAs CODCr Table 2 shows the reactors' performance data during the steady state condition at HRT 30 days.
If aimed at TWAS reduction, TADP is more suitable than MADP.
The VS reduction in TADP was same as that VSS reduction in MADP.
However, the VS reduction in MADP was lower than VSS reduction in TADP.

Statistics Indonesia [1] to reported data correspond with the Number of Motor Vehicles by Type, 2009-2013.
Sudin, et.al [2] were reported to review on the research performance of active and passive flow control on the vehicle aerodynamic drag reduction, and focusing the method to delay or prevent flow separation at the rear end of vehicle.
Post-processing of numerical simulation has presented the qualitative data such as velocity pathline and velocity vector, respectively, and quantitative data such as pressure coefficient (Cp), lift coefficient (CL) and drag coefficient (CD), respectively.
The velocity on the wake region become recover and contribute on drag reduction and downforce increase are correspond with increasing diffuser angle on rear body of the bus models.
Drag reduction are indicated by dcrease of drag coefficient with increasing diffuser angle on rear bus models.

At present, our country doesn’t have direct carbon emissions monitoring data.
According to industry statistics database provided by the export delivery value after 2008 and the difficulties of the data acquisition and accurate, this paper divides industries into 35 classes.
By looking at the China statistical yearbook and the energy consumption yearbook, we get the main energy consumption and industrial products’ energy consumption in our country from 2008 to 2012 through data sorting.
In view of this, the carbon cost of national industrial product must have a reliable carbon price to boost the development of carbon market, promote the country’s carbon emission reduction.
But in the long run, the implement of carbon cost may greatly contribute to the development of emission reduction techniques.

Fig. 1 Test sample sketch In this test, Q345 static strength data is given by MTS static tensile testing machine, and the fatigue strength data is given by Rama high-frequency fatigue testing machine.
(1) Where, b is sample width, h is the sample thickness, l is the span in three-point bending test (45mm is taken in this test), is the load amplitude, σ is the stress amplitude. 2.3.1 Fatigue test under the flame cutting process Based on the test data, the fatigue life of the sample under 340MPa, 360MPa and 350MPa are chosen for the S-N curve, which is shown in Fig. 5.
(3) 2.3.2 Fatigue test of ordinary Q345 Based on the experimental data, applying the least square fitting method, survival rate of the S-N curve of ordinary Q345 was obtained as 50%, and the S-N curve is shown in Fig. 6.
Fig. 6 S-N curve of Q345 Based on the test data, the S-N curve equation under the survival rate of 50% can be Fit as Eq. 4
(4) Based on the above test results, it can be found that the fatigue test data of Q345 is discrete, which is because that the material static and fatigue properties are unstable.

Unless stated otherwise the properties are as given in the CES[12] data base.
c Data from references [13, 14].
As mentioned, a 10 kg reduction in the mass of the car increases its fuel efficiency by 40 m/lg.
The α-values ($US/kg) indicate the cost penalty per kg of mass reduction.
The α-values (lg/kg) indicate the CO2 equivalent per kg of mass reduction.
