Introduction Electrodeposition technology, as a surface engineering technique, is utilized for modifying substrate surface properties or enhancing specific functionalities.
Despite the significant advantages of Ni-W alloy coatings in terms of hardness, various factors still influence the hardness during the electrodeposition process.
Various factors, such as current density, bath temperature, pH value, and agitation, have been identified as influential in determining the hardness of coating. 
According to the results in Fig.5, bath temperature, ammonium chloride concentration, and current density are the three most important factors affecting the hardness of the coating.
However, the model accuracy is somewhat affected due to the small dataset and limited input features used in this study.

Taguchi methodology is applied to make the association of these factors in optimization and through the observation of microstructure, hardness, wear-resistance and dilution rate to evaluate the effects of these factors on the hardfacing layer of the wear-resistant plate.
In Table 4, Torch moving distance (factor D) affects most on the surface hardness.
In table 5, Torch moving rate (factor C) affects the wear most.
In table 6, Working current (factor A) affects the most on the dilution rate.

However, in practical analysis, the convergence criterion is often affected by many factors, such as the element quality, the convergence criteria as well as the computation condition.
Wavelet method is endowed with the multiscale property, and it could extract the local property of studied signal or function.
According to this property, the singularity point in the curve can be figured out as well as the precursor load.
In this way the wavelet approach is validated. 2.69 2.95 Fig.3 The equivalent plastic strain of dam body under loading factor () Using the catastrophe method [10] and the finite difference method [11], the failure curve is also studied, and the corresponding precursor loading factors are 3.0 and 2.90 respectively.

The stable slope angle of above-water, level amplitude area and under-water were determined by physical and mechanical properties of rock, statistics of slope survey and experiences of reservoir.
Fig.4 Forecasting Range of Bank Collapse of Profile 2-2 According to the baseline of urban construction affected by bank collapse, the intensity of reservoir bank reformation was graded; the results are given in Table 4.

Thetransportofoxidantand fuel through the bipolarplatesis a significant factor affecting the cell performance.
However, graphite is high in cost, has low mechanical strength and the need for machining to form the flow channels [6].
The MEA properties are important because of the prominent effect to the cell performance.
Another factor such as type of MEA, manufacturing and experimental procedure are kept similar in order to have good agreement.
The main distinctive features are the mechanical resolution capabilities of this machine.

Flow properties of powder are the result of collective forces acting on the individual particles.
The flow of particulates affects manufacturing efficiency and dictates the quality of the end product, so many industries still rely heavily on flow properties.
The flow properties of particulates depend upon the combined effects of a large number of physical and environmental variables.
Here we focused on some factors to explore: Fig.3 is the influence of some factors on the particle orientation.
In optimization design, this paper analyzes several main factors affecting the deflection angle of particles, selected level according to actual need, not consider interactions between factors and meet the requirements of test design

Effect of Fiber Content and Fiber Orientation on the Tensile Strength in Glass Mat Reinforced Thermoplastic Sheet Jin-Woo Kim 1,a and Dong-Gi Lee2,b 1 Department of Precision Mechanical Engineering, Chosun University Graduate School, 375 Seosuk-Dong, Dong-Gu Gwangju, 501-759, Korea 2 Department of Mechatronics Engineering, Chosun University, 375 Seosuk-Dong, Dong-Gu, Gwangju, 501-759, Korea a jinu763@chosun.ac.kr, b dglee@chosun.ac.kr (corresponding author) Keywords: Glass Mat Reinforced Thermoplastic (GMT) Sheet, Fiber Content Ratio, Fiber Orientation Function, Fiber Orientation Angle Abstract.
Need the systematic study for the DB that can predict mechanical properties of composite material and fiber orientation distribution by the fiber content ratio was not constructed.
Therefore, this study investigated what affect the fiber content ratio and fiber orientation distribution have on the strength of composite sheet after making Glass Mat Reinforced Thermoplastic Sheet by changing fiber orientation distribution with the fiber content ratio.
Fiber orientation can happen by material factor such as intervening power of each fiber according to fiber diameter, the length of fiber, and molding factor such as closing speed of mold, molding press and the temperature of mold.
The products press-molded are not uniform because of fiber orientation and shows anisotropy, so it has a lot of effects on the mechanical properties of molded products [1, 2].

The overall performance is relative to the electrical properties, electrical conductivity, particle size and shape of its electric conduction phase as well as its distribution characteristics in the concrete [3].
So besides the three factors in the formula, the conductive fiber’s shape, size, physical properties, the interaction between components and other factors closely related to the corresponding parameters should also be introduced to establish mathematical mechanism.
It can be found that when we excluded the physical property and interactions factors between conductive fibers, there was a big deviation between values in fact and in theory.
What’s more, mechanical properties improvement is very limited.
(3) The formula shown that the factors affecting the conductivity were as follows: the conductivity of conductive fibers, dosage, L/D ratio (Length/Diameter), distribution, pliancy and affinity.

It is found that the most significant parameters affecting the cutting front development are feed speed and water pressure.
Further, the actual jet impact angle is dependent on both the water pressure and feed speed, but at higher water pressures the actual impact angle tends to become independent of feed speed, while water pressure becomes the dominating factor.
In the offset-mode turning shown in Fig.1(a), the waterjet is positioned in such a way that it is almost tangential to the workpiece as in a traditional turning operation with the consideration of the soft or flexible nature of the jet in affecting the final radius of the workpiece.
The relevant material properties are given in Table 1.
