Factors affecting the crack of HSS rolls Influence of HSS material The crystallization characteristics and chemical compositions of cast alloy have obvious influence on the hot crack.

Metallographic Inspection of the Piece: The piece was cut in an area outside the fracture area, Fig. 3, so as not to affect subsequent analyzes.
After that the mechanical properties of the fabrication material of the holder were obtained and, in addition, the typical zones of the fatigue fracture were determined; a simulation was carried out by the finite element method using the ANSYS computational tool [10] Results Characterization of the material of the piece (Holder) Results: AISI 4340 steel with high concentration of Cadmium (Table 1) Table 1.
The life to fatigue of the piece is shown in Fig. 8, it is observed that for the stress concentration factor kt=1 this is equal to 17780 cycles, a remarkable change when compared to the infinite life that results in the program without the presence of the generated hole.
It is also shown in the Fig. 8, how the surface defect reduces the cycles of the piece together with the stress concentration factor [12], [13].

The results indicate that the new highway geotechnical zone can better reflect the variation of rock-soil engineering properties in Shandong province.
The stability, security and economy of the highway structures, such as roadbed, pavement, bridges and tunnels, are closely related to the soil types and its engineering properties.
Different geotechnical types have different engineering properties.
Geotechnical areas were divided according to different engineering properties.
Different rock region reflect obviously different engineering properties.

However complex surface characteristics and hard and brittle properties of dental ceramic materials caused difficulties in the processing and subsequent grinding.
As a result, the quality of products was adversely affected [2, 19, 22, and 23].
Warnecke [4] pointed out that when we grind the new ceramic the grinding process the results are closely related to the mechanism of material removal .Material removal mechanism is determined by material properties, geometry abrasives, abrasive cut sports and acting on the work-piece and the abrasive elements such as mechanical and thermal loads.

Introduction It is a key task for a detection system to accurately detect and track important spatial targets, identify mission, size, shape, orbit parameters and other important target properties of the targets which have potential threats to the aerospace system, and distribute classified data [1].When the spatial target is in the shadow area, its visible light characteristics are obvious.
Fig. 4 Image gradient map after Line segmentation Fig. 5 Columns variance curve of row gradient image From Fig. 4, it is difficult to find a suitable dividing line to perform target image segmentation because there are a lot of confounding factors in the right of space target due to noise.
The noise shows strong variation in Fig.5 and seriously affecting the target segmentation, especially in the case of adhesion with the target noise.
With the target at specific environmental conditions and other factors change, the target image size, location, direction and shape will change, the paper proposed an effective small area matching method to solve this problem.

It was revealed that, in general the peak current significantly affected the EW and SR, while, the pulse duration mainly affected the MRR.
Performance characteristics such as EWR, MRR and Ra were evaluated with respect to discharge current, open voltage, pulse duration and duty factor by machining of Ti–6Al–4V alloy.
The quality of a machined surface is an important factor in evaluating the productivity of machine tools and machined parts.
Surface roughness is a significant design factor that has considerable influence on properties such as fatigue, strength and wear-resistance.

Introduction As the vertical transportation equipment of high buildings, elevator is generally located in the core area of buildings, so the quantity of the elevators and the determination of the layout of elevators directly affect the architectural design and architectural space organization.
Therefore, properties of elevators are affected by multiple factors, and traffic configuration process can be regarded as a multi-objective optimized problem, which can be solved by multi-objective optimization method [1].
Supposing that the balance coefficient of elevator is (0.4~0.5), the computing time is, the total mechanical transmission efficiency of the elevator is, and then the energy consumption of the elevators in the kth region can be expressed as the following equation:
are learning factors, and they are nonnegative constants. are mutually independent random numbers which belong to[0,1]. .

In recent years, with the rapid development of agricultural mechanization mechanized farming were carried out in field and compacted soil simultaneously, which caused the changes of soil structural properties, so that increased soil bulk density, decreased porosity and permeability to hinder water, air, heat transfer in soil layer, and also increased resistance to root penetration, affecting the crop nutrient to uptake, leading to reduction in crops yields[1].
Soil compaction impact on soil bulk density Soil bulk density is an important factor that reflects the soil structural characteristics.
The change of bulk density influences moisture, fertilizer, air, thermal conditions in soil directly or indirectly, thereby, affecting the crops growth.
Soil hardness changes after rolling Soil compaction impact on soil porosity Soil porosity is an important structural indicator to reflect the soil physical properties.
