In this paper, we implemented a High Profile Intra Predictor for H.264/AVC decoder on a novel coarse-grained reconfigurable processor- Remus (Reconfigurable Multi-media System).
RPU is a Coarse-Grained dynamic reconfigurable computing module and is the core element for computing-intensive task in the system.
For the High Resolution Video (1920x1088), this number could even be over 10k bytes, so these pixels could only be stored in the off-chip external memory.

Therefore, it is important to control the number and size of the inclusion in grade X100 pipeline or even higher grade pipeline.
Large number of high density dislocation tangle distributed in the ferrite plank internal, which improved remarkably tensile strength of the grade X100 pipeline.
The sub-grain size approximately is 5~6 μm.
From EBSD analysis, boundaries formed both among acicular ferrite and granular bainite is large-angle grain boundary as observed in Fig.10 (a), which can effectively resist the crack propagation by changing the route of crack propagation and consuming large number of energy.
Furthermore, because the microstructure of the grade X100 pipeline steel is composed of large number of small grains, it is possessed high strength and not easy deformed.

The evolution of texture and deformation in the grains during one pass of equal-channel angular pressing (ECAP) was examined for fine grained high strength and low strength Al alloys and a coarse grained low strength Al alloy.
Results reveal a number of reactions; they are labelled I to V in Fig. 3.
A soft, fine grained alloy.
A soft, coarse grained alloy.
In a coarse grained Al-Zr alloy fine new grains are created which share a common orientation with the original grain.

Thus the corrugation frequency does not relate to any particular microstructural feature, but rather is the result of the superimposition of a number of differential transverse strains that contribute to the overall deformation induced bending [7].
The diameter (equivalent circle diameter) of each grain along the scan was plotted and yielded some indication of grain size clustering, although the traces were quite noisy due to high frequency grain size variation (e.g. adjacent grains having vastly different grain size).
A much better graphical representation of the grain size clustering was obtained by plotting the mean grain size at each grain location by including 10 grains on either side of the targeted grain location.

Fig.°6 displays quite striking evidence for grain size clustering in sample A where the larger grain size bands can be up to 50 grains wide in TD.

After number of trial runs, process parameters such as rotational speed of 1000 rpm, welding speed of 50 mm/min and with average axial force of 30 kN was selected.
The predominant factor in controlling the size of recrystallized grains is the strain rate.
Grain size is greatly reduced with the higher strain rates.
The optical micrographs shown in Fig 2 clearly reveals the effect of FSP on grain size.
This decreased wear rate was caused by refined grain structure in FSP regions.

Change of mechanical properties of interfaces between different coarse-grained soils and concrete is investigated owing to the differences of materials.
Many scholars all over the world have carried out a number of effective researches[2-9].
Therefore, change of mechanical properties of interfaces between different coarse-grained soils (weakly weathered sandstone with distinct edges and sand-gravel materials with good roundness) and concrete is investigated owing to the differences of materials by means of large interface test apparatus.
Conclusions Change of mechanical properties of interfaces between different coarse-grained soils (weakly weathered sandstone with distinct edges and sand-gravel materials with good roundness) and concrete is investigated owing to the differences of materials based on the Goodman element by means of large interface direct shear apparatus.

Discrete Voronoi tessellation is used to adopt grain structure for CA simulation.
It allows to obtain structure of different grain sizes and geometries with randomly distributed grain seed points.
Number of grain seed point nseed is the one parameter defining the grain structure in case of homogeneous seed point distribution.
According to Eq. 3 when strain is increasing, number of damaged cells is increasing as well, what allows for growth of voids enhanced by deformation.
Damaged cells are moving freely inside grains simulating diffusion of vacancies.

For most cast light alloys, the addition of a grain refiner to the molten metal prior to casting is one of the most important ways to reduce the final grain size and tone up mechanical properties of commercial castings.
Although very efficient grain refiners, such as TiB2 and Al3Ti, have been used successfully in the aluminium industry, the practical grain refinement of magnesium alloys is still limited[2].
Because Zr, as the most promising grain refiner for Mg alloys, can not be used in Mg alloys containing Al, Mn or Si addition, considerable effort has been devoted to seeking reliable, easily applicable grain refiners for Mg–Al based alloys[3].

A similar phenomenon has been observed in the grain refinement of an Mg–Zn–Ca alloy by Zr addition , while the maximum grain refinement efficiency was obtained at 0.22 wt% Zr under sand casting conditions[13].

The last two properties are mainly controlled by the grain structure/size in the material and show opposite trends with increasing grain size: mechanical strength decreases whereas the material becomes less subject to corrosion.
The solute still in solid solution may precipitate inside grains and/or on subgrain/grain boundaries, hindering their migrations and leading then to slow kinetics and coarse grains.
The model is based on the discretization of the radius distribution for each type of precipitate and the determination of the precipitate number density in each class is performed at each time step [1].
It is achieved by introducing a new distribution which determines the number of iron atoms trapped in the precipitates of size r and r+dr and is governed by the following partial differential equation: (2) with m, n and p the stoichiometric numbers respectively for Al, atomic sites for Fe and Mn, and Si, the mean atomic volume inside the precipitates, the fraction of Fe, Mn sites occupied by iron atoms at the interface matrix/precipitates.
The nucleation of recrystallized grains is covered elsewhere in the literature [7].

Higher number density of crater was obtained on the irradiated surface of cold rolled sample compare to its annealed sample counterpart.
The dense deformation bands existed in every grain, and these bands never through the grain boundary.
Figure 2(a) reveals that both dislocation loops (DL: indicated by the arrows) and triangular shape of the defects below 10nm in size (indicated by the circles) were formed after HCPEB irradiation, and large numbers of deformation microbands were synchronously introduced.
For the irradiated samples with the considerable defect structures and significant volume fraction of grain boundaries, the excess vacancies can find a sinks easily and quickly.
For annealed sample, many micropores with larger sizes (about 1-2 mm) are the preferred form at the regions of original grain boundaries and relative lower number density of the micropores was presented within the interior of grains.
