Focused Ion beam thinning(FIB) can be used to select desired mesoscale features from among large numbers of micro scale features at depths of several microns below the surface of the sample, which is applied beyond sample preparation[3] [4].
When stiffened polishing tool rotates relatively to sample, abrasive grains among stiffened zone is drive down to wipe sample’s surface.
Solution accuracy is set at 0.001 and upper limit of total iteration number is fifteen times.

While the use of cast components is fairly well introduced in a wide number of applications which are ranging from steering wheels, instrumental panels and even to hybrid engine blocks the use of magnesium wrought materials for production of sheet, forgings or extrusions is still limited.
This concerns a limited knowledge on the processability as well as a limited number of suitable wrought alloys.
High temperature for a long period might cause grain growth so 350°C was chosen as a compromise.

But from the experiences of the third-generation Synchrotron Radiation Facilities operated in the world, it has been observed that this criterion is too conservative for the expected low number of thermal cycles (~10,000 cycles in 30 years of service).
This model takes the maximum principal strain as the damage parameter and leads to the following formula. 1 ' (2 ) ' (2 ) 2 f b c f f f N N E σε ε ∆ = + (1) where 1/ 2ε∆ is the maximum principal strain amplitude, 'fσ is the fatigue strength coefficient, b is the fatigue strength exponent, 'fε is the fatigue ductility coefficient, c is the fatigue ductility exponent and E is the Young's modulus. fN is the fatigue crack initiation life which is the number of load cycles when a grain size (~1mm) crack forms.

In WDM mesh networks the use of the idle capacity by multi-hop light-paths is complicated by the need of re-dimensioning core nodes, resizing transport links and reconfiguring a large number of optical switches [4].
In a multi hop network, to communicate from a source to a destination, it is necessary to use a composite light-path consisting of a number of light-paths.
Although switching by using fine-grained switching capable devices holds higher flexibility, it incurs higher device costs as well.

First, odd numbered outer dies and inner dies press the trial pipe and return to the starting position.
Second, the even numbered outer dies and inner dies press the trial pipe, and all dies return to the starting position.

It can be seen obviously from Fig. 1 there is no absorption at around wave number 2270cm-1 which indicates that the NCO group of IPDI has reacted completely [8]; there is no absorption at around wave number 3640cm-1 as well which indicates that the primary OH group of the feeding materials PPG, DMPA, and BDO has reacted completely.
It can be seen obviously that the angular grains of HNIW become blunt after being coated, which will reduce the possibility of forming hot spots.

The concentration of each element isn’t necessarily equi-molar but it can be between 5% and 35% which allows the possibility of the number of high-entropy alloys systems to grow [10, 11]. 2.
Well obviously limits are the primary grains.

The basic research question is that in multi-Agent system behavior modeling and coordination of relatively coarse-grained problem solver between the contents of the study involving distributed sensing, inter state prediction, architecture, fault diagnosis, Multi-Agent System, Agent communication and coordination, and so on.
After obtaining the information fusion system or device monitoring information, carried by a number of state recognition Agent troubleshooting and diagnostic analysis based on different methods and rules, the final decision by the diagnostic conclusions obtained information fusion process.
As shown, the input layer corresponds to a failure in which the phenomenon of the output layer corresponding to the cause of the fault,there are provided m the input layer nodes LA, LC output layer has n nodes, the number of nodes in the hidden layer LB u.

The coating surface was composed of grains with different diameters, which are melted and unevenly distributed on the coating surface.
However, the number decreases to 470 HV after 60 min friction and wear test.
A number of adhesion tests were also performed.
