A statistical approach is introduced to extract quantitative information
on the chord length distribution of grains from orientation data gathered by electron back-scattering
diffraction.
Both procedures can easily be adapted to orientation data: If orientation data are gathered on grid lines with a constant step size ∆x between subsequent points, disorientation angles between all N point pairs consisting of neighboring points along the grid lines can be calculated.
# . (9)5 Determination of chord length distribution from experimental orientation data.
The suggested methodology is illustrated for an aluminium polycrystal cold-rolled to 90 % reduction and annealed to complete recrystallization.

The interaction between k-carrageenan (biopolymer) and silver ions causes the reduction of silver nitrate and the synthesis of AgNPs.
Therefore, these molecules contribute to both the reduction and stabilization of Ag ions [19].

Therefore, these molecules contribute to both the reduction and stabilization of Ag ions [19].
The r value obtained is 0.9948 so it can be said that the linearity data is declared valid and there is a correlation between concentration and intensity.

In this paper de-noising technique is considered for reduction of noise.
The optical wireless system also offers high data rates and inherent security since the light does not penetrate the walls.
Both links are affected by multipath dispersions due to multiple reflections which limit the data rate.

Additionally, a validation from the simulation through a comparison with the experimental data at similar conditions was performed.
The results presented a good agreement between the experimental and simulated data.
It was considered also, that the oxidation and reduction reactions were in equilibrium.

Inverse analysis is regarded as an ideal way to achieve the mechanical parameters of rock mass using in situ measured deformation data of surrounding rock during the construction of underground engineering.
It can be seen that although the number of support vectors of LS-SVM was more than that of standard SVM, the time comsumed for back analysis of the former is obviously less than that of the latter, which, to a great extent, may be explained as the significant reduction of computational complexity for LS-SVM.

Cement content of 550 kg/m³, water/binder ratio of 0.35, binder/cement ratio of 2.00 and fly ash replacement 10%,20%, 40%, and 60% were adopted for the mix proportion.The relationship to look into are the potential of CO2 reduction in the mortar mixes while cement content were replace by fly ash.
The CO2 footprint of each mix was calculated from the mix proportion as shown in Table 2 and the CO2 emission inventory data shown in Fig. 1.

At the transmitter, the spectrum of white light sent to user #k’s spectral component can be expressed as when the data bit is “1”; in contrast, it sends (the complementary spectral component of user #k) when the data bit is “0”.
With the unipolar encoding structure for the SAC-OCDMA system, the user #k spectral is sent to the spectral component when the data bit is “1”.
However, when the data bit is “0”, it does not send a spectral component.
The data bit source we adopted was a PRBS generator component to generate random binary codes, and the sequence code is .

(a) the conventional layout algorithm (b) the remaining rectangle layout algorithm
Fig. 1 The remaining rectangle layout algorithm superiority schematic
The remaining rectangular layout algorithm with a rectangular data set to represent the current surplus space of the chamber situation.
Then at the beginning of the remaining rectangle data set only one rectangular is R1=[(0, 0), (W, H))]. 2) When discharged into a rectangular piece i (W wi high-hi), each rectangle in the remaining rectangle data collection needs to lose this amount of rectangular pieces space.
Fig. 2 Schematic diagrams of the remaining rectangular coordinates So, all the remaining rectangle in the rectangular data set for this operation are subtracted rectangular pieces i, the formation of new remaining rectangle. 3) Because the generation of the new remaining rectangular, will cause changes of the original rectangle data sets: Remove the remaining rectangular area of zero or has been unable to arrange any remaining pieces of a rectangle; Removed the small rectangular area in the remaining rectangle with a fully contained relations, and reserved all rectangles of intersecting relationship.
Through data validation, in the congestion of navigation conditions, the average utilization rate of lock chamber is over 80%, compared to the arrangement by manual work, improved by more than 20%.
