In this area user defined superpixel are created by summing the intensity over the given number
of pixel in x and y direction (Fig. 2).
This structure has its origin in the grain size of the investigated Mg-Alloy sheet (see also Fig. 3).
If the number of grains contributing to the reflection intensity registered in the detector pixel or superpixel is not sufficient, the fit of the Gaussian will not result in usable values for some Ψ positions.
Both methods are working in an array of an odd number of superpixel.
The different values in neighbouring superpixel in that region have their origin in different grains.

It could be contributed to that the strong reducing agent NaBH4 in combination with an intense stiring during the reductive process creates a large number of nuclei, which limited the growth of graines.
In the case of C-foam matrix (Fig. 2, c-e) Cu-Sn nanoparticles are synthesized not only in the pores of a C-foam, but also on the surface of the carbon grains.
The dependence of the efficiency vs. the cycle number for the both electrodes is presented in Fig. 5.
Coulombic efficiencies vs. number of cycles for the Cu6Sn5 alloy and С-Cu6Sn5 composite electrodes Fig. 4.
The used complex agent (citric acid) is important for the formation of nanoparticles on C-grains surface or in the pores between the C-grains.

Fig. 2 shows the structure of CaCO3 bridges precipitated between grains of
only slightly compacted pure sand.
Figure 2: Fine structure of CaCO3 crystals in matrix connecting sand grains, (e.g. a spherical grain in the right upper corner), see also Fig.7 (photo G.
However, the treatment of lean mortars, well compacted and cohesive, with a high number of repetitions of lime water wetting, can also cause significant compression strengthening.
Of course, this example shows the result of a quite high number of repetitions of treatment cycles, and such dense filling is not necessary for consolidating degraded mortars in practice.
Nosál) Lower concentrations of CaLoSiL and also a reduced number of treatment repetitions resulted in a thinner matrix layer covering and connecting the composite grains.

The
formation of these pinholes is due to the inability of conformal coverage of the sub-micron sized
cavities that are created by these Ag grains.
Therefore, 2 scL the number of cells with R greater than 30 cm yield the total number of cells Y ?
A structure of large embedded crystal grains is observed with surfaces under acute angles to the substrate.
Such a substrate may give rise to cavities that are not filled by the successive depositions (ZnO and Si) due to the shadowing effect of these large grains.
The sample shown in Fig.3b clearly has a larger number of voids, and indeed is found to have a low FF.

Optical microscopy was conducted on all specimens so as to obtain information about the number
and nature of shear bands in the as-deformed material.
Volume fraction of grains containing shear bands after rolling at 640 and 700ºC.
Cold rolling creates more deformed grains of high stored energy; this increases the driving force for recrystallization on annealing and also increases the number of {111} nucleation sites.
The first creates more sites for the nucleation of {111} type grains and the second allows these orientations to grow.
C and N in the form of coarse precipitates do not interfere with the nucleation and growth of {111} grains.

Biodegradable and bioabsorbable magnesium – based alloys provide a number of benefits over traditional permanent implants.
The structures evidence grains of solid solution of polyhedral shape and a relatively uniform granulation.
In this case the structure of the solid solution grains presents a dimensional variety.
An accentuated of the solid solution grain granulation was observed, and deposits of Mg2Ca were evidenced in XRD figure (figure 7).
This increase in granulation, together with the increase in Ca percentage, insures the possibility of an accentuated reactivity at the boundary between grains, a favorable aspect for our aim of proposing these alloys as biodegradable implants.

The amount of adhered chips on cutting tool increase as the number of hole drilling process increases.
However, since glass is a brittle material and does not have crystal grain boundary and pore, crack is easy to progress as a crack starts to occur.
Black part shows diamond abrasive grains.
Abrasive grains using diamond, grain size is No.600, abrasive grains are electrodeposited on nickel.
The difference in the number of carbon atoms of the lipophilic groups is considered to affect the adsorptive glass cutting scrap generated in the experiment[3].

Although the coarse-grained model is less accurate than a full atomic model, its potential to investigate material properties over longer length/time scales makes it feasible for large polymer systems [9-11].
Moreover, we have calculated the cumulative number of lubricant chains Nevp that have evaporated from the surface and those Ndep that have depleted away from the heating region, i.e., Nevp = 1991 and Ndep = 14397, respectively.
Ultrathin PFPE film was characterized by a coarse-grained model and was deposited onto an inert substrate.

In the framework of the virtual machine can be well applied to cloud computing platforms such as multi- level security environment for guest virtual machines and communication between the fine-grained access control to prevent malicious software attacks and the spread between the guest virtual machine.
In addition, the monitoring mechanism and the separation of the virtual machine to be monitored, but also makes this method can not be fine-grained monitoring.
