This CAD modeling data can be transform to other layered algorithm such as STL [7].
Therefore, it is worth if the wood based furniture prototypes and architecture mock up can be produced by 3DP as it could contribute to the cost reduction and reduce time in producing the prototype and mock up.
An increase of wood powder would result in reduction of the dimensional accuracy and improve the hardness properties.

If adopting a single frequency notch filter to process, as soon as it would result in the undesirable effects of the target signal distortion or noise reduction.
Steps to Achieve the Separation of Drill String Vibration Periodic Noise (a)Initialize the observed signals: put the any two-dimensional signals of the collected three-dimensional drill string vibration signals into initialization mix, and get three observed signals; (b)Data preprocessing: after demeaning value and whitening process of , signal X in which each of the signal components are mutually orthogonal will be obtained.
An Algorithm for Periodic Noise Reduction Based on ICA[J].

From the data in Table 1, it was apparent that the refractive index of silicone resin increased with increasing phenyl content.
This behavior was due to the reduction of free volume with the present of bulky size of phenyl rings as the pendent groups.
The refractive index was successfully increased with increasing the phenyl content due to the reduction of free volume with the present of bulky size of phenyl rings as the pendent groups.

Consequently, recycling these metals leads to the preservation of natural resources, cost reduction and the reducing of greenhouse emissions [1].

A classic method for gold recovery, that should be considered in the future research, is the treatment by cyanide, while taking into account the reduction of environmental impact caused of by-products.

However, compared with the Al1 and Al2 samples, the absorption band at 982 cm-1 of the Al3-Al5 samples shifted slightly to the lower wavenumber, which is due to the reduction of CaO in the samples and the reduction of free oxygen in the glass, resulting in the existence of Al3+ in the form of [AlO6], and the volume is larger than the [SiO4].

However, the content ratio of OPS controlled the reductions in the tensile strength of concrete [6].
These reductions in the mechanical properties can be compensated by adding single or hybrid fibres to the concrete mixtures [7].

The glasses doped or co-doped with rare-earth ions have generated much interest due to the possibility of several promising applications such as fiber amplifier, visible laser, optical data storage, sensors and optical communication devices [5, 6].
Our results are in good agreement with previous report in which the addition of rare-earth to the oxide glass shows a reduction in optical band gaps as well as Urbach energies with the densification of the glass network [15].
Performance reduction and design modification of erbium-doped fiber amplifiers resulting from pair-induced quenching.

One can observe the substantial fcc-Al peak broadening with decreasing of extrusion temperature, suggesting nanosized fcc-Al grains, and the Al3Fe peak contraction and intensity reduction with the extrusion temperature increasing, indicating both precipitate coarsening and dissolution. 30 35 40 45 50 2θθθθ (deg) Intensity Al3Fe 375 o C 400 o C 425 o C Powder Al3Fe Figure 1 - XRD patterns of the processed bulk Al-3.0Fe-0.42Cu-0.37Mn powder alloy after extrusion.
The data points were fitted to a representative curve to obtain the approximate behaviour between 25°C and the other temperatures.
But when the temperature is increased up to the critical value, the coarsening and dissolving of the precipitates will occur with the temperature increasing, leading to the reduction or disappearance of the pinning effect of the precipitates and thus decreasing the activation energy even as the effect of increasing temperature on enhancement of the GGR becomes more important.

This process also obeys theory of metal forming principle by means of thickness reduction compensated by stretching.
The result in Fig. 6 is the result of simulation and the data taken from ABAQUS 6.13 software. 4.
This paper also investigated an experiment to demonstrate practically that through reduction in thickness of the sheet, it is possible to manufacture a dish like products.

According to the model of strain-induced movement of the grain boundaries [5], the driving forces for static recrystallisation may be estimated from the reduction in stored energy per unit of volume crossed by a recrystallisation front, considering that the process which intervenes is a reduction in the density of dislocations.
This data was used to calculate the driving forces for grain growth by means of equation (1), and the results are also shown in Table 2.
