Abstract.
Therefore, in this research energy reduction of refined sugar drying and conditioning process study of these phenomena was conducted both experimentally and theoretically.
Evaluation of these results showed that the low humidity of fresh air are well suited for applied of refined sugar drying process, giving the perfect performance in which quality of refined sugar impacted can be eliminated and reduction of energy can thereby improve, with the aim of enhancing energy saving.
Conclusion In this paper the research topics were fitting a set of data collected during in February to May 2013 in rotary dryer and conditioning silo in sugar factory located in Thailand.

One of the significant problems is the identification of the material data and the characteristics of the impact of the tools on frictional materials.
This allowed for the reduction of task and for the acceleration calculations.
The adopted data should be verified.
You must specify the data as an increasing function of pressure and overclosure.
Tested models were also differed in the data used to describe the elasto-plastic characteristics.

The results show a systematic variation in the deformation texture with changes in Q
(the ratio of the reduction in thickness to reduction in diameter).
Initially, data from each section were averaged to determine the hardness increase towards the heavily deformed end of the tube.
Results and Discussion Texture evolution of pilgered tube The ratio of reduction of wall thickness (RW) to reduction of diameter (RD) is a key characteristic of the pilgering process and is defined as Q.
RW/RD)>1, the reduction in wall thickness dominates.
It can be seen that the Q values for each section of tube vary from less than 1 for small reductions, to slightly greater than 1 as the reduction is increased.

The starting microstructures for the simulations were
generated from experimental data taken using electron backscatter pattern analysis.
Although the EBSP data is already discretized in a form suitable for input into a Monte Carlo Potts model, as a result of noise in the experimental data some pre-processing of the data is also necessary.
For starting microstructures with higher cube-fractions ( ≈ 65%) , the evolution more closely matches the experimental data.
In accordance with a large amount of experimental data, the energy of the grain boundaries in the system was defined in each case according to the Read-Shockley equation, with a minimum value set at 0.1 [7]: ( ) ( ) [ ] −θθ =γ 1 ]ln1[/,1.0max m m θ/θ m m θ>θ θ≤θ : : (3) Less experimental data exists for the variation of boundary mobility with misorientation.
Only a small advantage (Λ=1.02, or cube grain surface energies ≈ 2% lower those of other grains) is necessary to give a noticable cube-texture enhancement to levels comparable with the experimental data.

The
alumina/nickel composite powder following reduction in hydrogen atmosphere was sintered using a
pulse electric current sintering method.
The powder is soaked in metallic salt solution in vacuum, followed by filtering, calcination, and reduction in hydrogen.
Fig. 3 TEM observation of nanosized nickel particles within γ-alumina after reduction.
The modified relation between the averaged data for the monolithic alumina, as-sintered nanocomposites, and annealed nanocomposites is shown in Fig. 7, where the data for as-sintered nanocomposites sintered at 1550 ºC and the data for annealed nanocomposites annealed for 10 min were omitted because these data were affected by over-annealing conditions.
Table 1 shows the average values of the experimental results of monolithic alumina, as-sintered nanocomposites, and annealed nanocomposites for the alumina/nickel system, where data of the specimens sintered at 1350ºC were selected.

In order to cancel effects of noise as much as possible some
measures have to be taken for data manipulation noise cancellation, such as averaging, inverse
filtering and so on.
In order to minimize spurious peaks, which widths are less than 2j samples, the sampled data are made smooth by performing the moving average of the data sequence: [ ] [ ] [ ] [ ]1 1 32 1 +++�= nycnycnycny , 1321 =++ ccc . (5) This is equivalent to operate the Hanning spectral window.
To perform the subtraction, first data are taken from the test object without presence of any target.
Another data are taken with the presence of target.
Lets consider the model of received discrete noisy signal ][][][ nnynz += , Ni ,...,1= . (9) To reconstruct the original data, a wavelet representation is used [4].
