This can be done by the fabrication of metal-matrix composite (MMC) materials (hardened with particles, whiskers, fibers or layers) [3-6] or/and fine-grained materials [7].
In both cases the increase of mechanical properties is observed, but a number of factors restrain further improvement of material characteristics: the problem of wettability and uniform mixing of phases; high cost and complexity; insufficient elaboration of technologies for combining components [8].
To obtain a fine-grained structure one has to solve two problems: (a) - fabrication of the weakly agglomerated nanosized initial powders and (b) - effective overcoming of interparticle friction forces during consolidation.
In a number of experiments, a controlled oxygen supply with a flow rate of 0.17-1 cm3/s was used.
The numbers show the amount of the oxide phase in the corresponding composites in weight percent.

(Liu [5])An uncertain variable is a measurable function from an uncertainty space (,,) to the set of real numbers, i.e., for any Borel set B of real numbers, the set is an event.
(Liu [5]) The uncertainty distribution Φ of an uncertain variable is defined by for any real number .
Repeat the second to sixth steps a given number of cycles.

Beside, most of crystalline grains in the diamond layer have combined into the D-D structure.

Concrete mixes denoted as R3, R4, R5, and R6 containing aggregate grains of size ranges 0–4 mm, 0–8 mm, 0–16 mm, and 0–22 mm were tested (details on material characteristics listed in [6]).
Applied model was formed by cells with minimum diameter of 2 mm (see Fig. 2b) with the number of nodes about to 60,000 and number of springs about to 500,000.
Lower number of fracture events against FyDiK3D numerical model is due to FE mesh size – unfortunately when the smaller size is used, there is the greater trouble with evaluating.
But absolute value of the number of events cannot be compared – there is necessity to compare relative one.

The number and angle of small angle grain boundaries determine the mozaicity.
In this image the number of neutrons reaching the given point is shown by the intensity of the point.
The lighter is the point, the number of impacts is the greater.
The elements of A matrix are given by the numbers of neutrons reaching the given point during the measurement period.

The number of cracks initiated on the coating surface is the most under IF and the least under IP TMF.
Tests were stopped after a defined number of cycles and the crack density in substrate was determined by SEM.
Fine-grained MCrAlY coating shows ductile deformation behavior and low strength at high temperatures and brittle behavior and high strength below a certain temperature (called ductile-to-brittle transition Coating temperature, DBTT).
Micro-crack density in M963 substrate versus number of cycles in OP TMF for Δε mech/2=0.35%.
The number of cracks initiated on the coating surface is the most under IF and the least under IP TMF.

In particular, Pao et.al. [5] employed molecular dynamic simulations to analyze the stress during the deposition on a substrate intersected by the grain boundaries.
The number of deposited atoms was measured in the units of a complete monolayer (ML), where one monolayer consists of atoms of the substrate.
The scattered X-ray intensity is calculated from the equation: where N is the number of simulated in-plane points, M is the number of atoms in the i-th column, is the X-ray wavelength, is the atomic scattering factor, and is the distance of the considered atom from the reference level.
As the number of deposited atoms increase, the stress tends to compression direction.

Introduction Wireless sensor network is a distributed network system consisting of a large number of tiny sensor nodes.
Due to the limited resources of wireless sensor nodes, the number of messages stored in the MessagePool is limited, so the MessagePool will overflow and packet loss occurs.
TACK message length fcf dsn dest src Times 1Byte 2Byte 1Byte 2Byte 2Byte 1Byte While N number of MessagePool, the node returns TACK, and the Timers of TACK is equal to zero.
From Fig.6 we know that the delay increases with the increase of number of forward node, and the delay in NCTP increases faster than that in CTP.
Furthermore, the system has been deployed in the monitoring system of grain reserves, and it turns out to be reliable.

Considering CUDA programming features, we design the fine grain data parallel algorithm based on cells.

As the result, the pressure contours are shown in Fig. 4. 4.2 Performance on Single GPU The flow around ellipsoid at a Reynolds number of and with the angle of attack of is chosen for performance measurements.

The stepping motor was run by the motor control unit, in which a rotation speed, the number of discharges and a delay time for charging to the capacitor bank had been inputted by the PC.
After the number of discharges decided by PC was completed, nanosized powder in the chamber was evacuated with N2 gas by the rotary pump and captured in the collection chamber.
In images, grains were observed.
The particle size distribution is broadened and the particle diameters are increased with the increase in the number of discharges.
The distribution was broadened with the increase in the number of discharges, because of condensation of the particles or deposition of plasma.
