Saboori et al., 2006 have determined the extrusion energy for the two optimal conical and curved dies, for aluminum and lead billets, in forward and backward extrusion by using FEM with verification of experimental data.
All the input data generated in the pre-processor can be saved (i) in a text form which enables the user to access the input data through any text editor; and/or (ii) in a binary form which is used by the simulation engine (Kim et al., 1994) explained below.

On the contrary, as for CO2 emissions, the recycled rebar showed a 88.3% reduction possibility of greenhouse gas (GHG) emissions comparing to statistics of input-output analysis based on competition inducement coefficient, but it was found to be more disadvantageous from the perspective of GHG reduction than the statistics of input-output analysis based on non-competition inducement coefficient.

On the contrary, trapezoidal numerical integrals were exploited to process the fluctuated-data, which were in good agreement with the predictions.
Fig. 4 Signal of sensor 5 by lowpass filter Fig. 5 FFT result of raw signal by sensor 5 Alternatively, fast Fourier transforms were performed as traditional data processing.
Since it was inconvenient to process the 40s data if it was separated to 10 parts, and it was not certain that the exact amplitude could be extracted for each part successfully.

Rough point cloud data
Point Cloud Data Processing
A. noise reduction and smoothness.
Effective noise reduction and smoothness algorithm should remove the noise points and retain the sharp feature of the point cloud to prevent that the point cloud data was over-smoothing.
In the past years, Most noise reduction and smoothness algorithm were about the 3D mesh, very few were about the 3D point cloud data.
The point cloud data was separated into the detail data and the foundation data.
The foundation data was taken noise reducing and smoothing, and the detail data was retained.

Data reduction is a consequence of the fact that the number of end-members presents in the scene is usually much smaller than the number of bands.
Dimensional reduction is categorized in two ways: Feature Extraction is done by mapping the correlation of high dimensional data onto uncorrelated low dimensional data.
Unmixing of hyperspectral data is usually carried out the two steps.
Initializing the data by eliminating noise [2].

Data set
The data set taken from Chou and Cai [5] are used to test the current method.
If the high-dimensional data lies on or near a curved manifold, such as in the Swissroll dataset, MDS might consider two data points as near points, whereas their distance over the manifold is much larger than the typical interpoint distance.
However, Isomap is a technique that resolves this problem by attempting to preserve pairwise geodesic (or curvilinear) distances between data points.
These neighborhood relations are represented as a neighborhood graphover the data points, with edges of weight between neighboring points. 2.
A global geometric framework for nonlinear dimensionality reduction.
