A large number of parameters and the information can be gotten from obtaining image with computer vision technology, and not need measurement object, with the advantages of high efficiency, high recognition rate and unified standard.
In 2007, Wu Yanhong and others developed a rice quality detection system based on computer vision technology, single grain image could be extracted from the group grain image through this system.

Check the penetration and the number of equilibrium iterations used in each substep.
It also enables us like prospect to project studies and tests under different type of grains resulting from different materials in order to illustrate the friction behavior of the concrete mixture.
To also announce that as a prospect, the contacts friction problems are governed by any factors purely related to the surface state of the grains like surface roughness, thing which one did not take into account in our study.

Coarse aggregate: granite detritus with 5mm-20mm grain size.
Both manpower and vibration platform are used to make concrete close-grained enough.
The number of the slippage lines increased with the load.

SIFCON is prepared by infiltrating pre-placed fibres with fine grain aggregate mortar.
Fine SiO2 sand with grain size of 0-1 mm, cement CEM 52.5R and water were the main components of the slurry mixture.
The total absorbed energy is obtained using the following formula: E = m.ag.h.x Where: E…Total absorbed energy [J] m…Weight of the impactor [g] ag…Gravity acceleration [m.s-2] h…Height of drop [m] x…Number of the drops [-] DE 50/1 RB 80/50 BN DE 30/08 FRC - reference DE 30/06 N DE 50/08 Figure 1 Selected slabs after drop test – different failure modes A comparison of total energy-absorption capacities of different slab specimens at ultimate impact strength stages is presented in Figure 3.

Introduction Oil shale is fine-grained sedimentary rock including native organic matter, not dissolving in petroleum solvents and can extracting a lot of oil shale with pyrolysis[[] Liu Baiqian.
Take 40 g Fushun oil shale from sterile flasks, add 400 mL of sterile saline (m·v-1 = 0.85%), 30 ℃ 150 r· min-1 shock 30 min, the rock grains evenly dispersed in a suspension in sterile saline, to get an oil shale 10-1 bacteria. 2.
From Fig.5, which ZYK7 growing more lush, while the other two strains are growing poorer and smaller number of amplified by PCR ZYK7 rDNA ITS region, its molecular identification, the strains in Genbank Fusarium oxysporum (JF807394) 100% homology.

First, the results suggest that IGSCC of sensitized 304 stainless steel occurs because of the formation of films of α-M2O3 along sensitized grain boundaries.
Second, the results suggest that HWC is effective because HWC lowers the potential at crack tips to values less than -400 mV so that films of M3O4, rather than α-M2O3, form along sensitized grain boundaries.
The spectra at potentials above -750 mV display a number of potential-dependent changes.

Additionally, the Ti64 alloy fabricated via BEPM exhibits finer α-grains and intragranular β-lamellae compared to the coarse-grained lamellar structure of the conventionally cast and wrought alloy, with these microstructural differences becoming more pronounced under high dynamic impact [10].
Due to test limitations (plate size and number of tests), a rigid comparison isn’t possible, but reasonable estimates can be made using SKE data of BEPM made laminates.

Established correlation for aluminum alloys have shown that the alloys must at least exhibit a 110 Vickers hardness number (HVN)
It may be seen the disclosed alloy exhibits fairly large grains, all continuously decorated with gallium.
Due to its continuous grain boundary network of gallium, the alloy depicted in Figure 4 inherently possesses limited tensile properties, and turned out to be of limited usefulness.

System differences may performance in cement particle size distribution, grain type , which is the physical aspect,and the impact of accessory types and chemical composition in the production process of ordinary Portland cement,which can by adding to mixed material to adjust the gradation and reduce the impact of cement materials composition.
(2) The results showed that there are system differences exist in the adaptable of different cement Polycarboxylate superplasticizers[7],these differences caused by the physical and chemical properties, graded cement particles, grain types and the types of accessories all have an impact

As a result, the impact of flap abrasive grains on the surface of the contact spot will differ significantly, which leads to uneven metal removal along the processing width.
The best quality of grinding will be achieved when this gap is completely eliminated, since in this case the impact of the flap wheels on the contact surface will be the same both in terms of the impact force and number of abrasive grains.
