The Ti64 SLM components show similar or superior physical and mechanical properties compared to the precursor material without employing any post-processing methods [5].
The mechanical properties of the components are sensitive to their microstructures [6] and depend on the SLM process parameters which are discussed in detail in section 2.
Mechanical Properties of SLM Ti64 Alloy.
Robust optimisation outcomes can only be achieved if based on a comprehensive understanding of the associated mechanical properties and manufacturing limitations.

The size of the undercut and the neck thickness of the upper sheet mainly affect the mechanical strength of the joint.
Depending on the properties of the used materials, the clinching point fails either because of button separation or neck fracture, which is caused by insufficient undercut or thinning of the neck, respectively [6].
Both factors improve the symmetry of the joint shape.
Two important factors basically control the material flow during the roller clinching process.
If desired, the anisotropic properties can be emphasized with reference to the intended use by changing the blank holder geometry or the rolling radii.

Meanwhile, FS membrane was added by pectin to increase the hydrophilic properties.
These two membranes are compared due to several factors that will determine which membrane is more suitable for use in the treatment of pome waste.
While inorganic membranes may offer certain advantages, such as good hydrophilicity, selectivity, permeability, mechanical strength, and thermal and chemical stability [33, 34], polymer-based membranes stand out for their inexpensiveness, ease of processing, and relatively better mechanical properties [35].
Pectin was added to the fabrication of the membranes to improve the hydrophilic properties [42].
PVDF has strong chemical and mechanical resistance properties, considered more suitable in this process due to POME characteristic that high in chemical matter [56].

In this paper, firstly, we give a brief introduction of the amorphous alloy material properties and compare the no-load characteristic of the AMMT with the SSMT.
Compared to silicon, the amorphous alloy material has the following characteristics: The amorphous alloy core is thin, the thickness is just 20 to 30μm, the fill factor is low; The amorphous alloy core has low saturation flux density; The amorphous alloy is five times firm than silicon steel; The amorphous alloy core’s material is very sensitive to mechanical stress and affects its magnetic properties [1].

SEREP (System Equivalent Reduction-Expansion Process) method was used to
conduct the prediction research and the procedure was elaborated in detail theoretically first, then
several simulations were carried on to demonstrate the prediction procedure, inspect the accuracy
under various loads and investigate the factors which may influence the accuracy including the
number of modes used in the prediction, the noise, and the measured points.
Therefore, in the field of aerospace and mechanical engineering, structural vibration test is always considered as one of the most important means to verify that if the products or structures have good adaptability to the vibration environment, and to assess their dynamic performance.
As for the material property, Young's modulus E=70Gpa, Poisson's ratio ν=0.3, density ρ=2700 kg/ m3.In the element model (Fig 2(a)), 231 nodes and 200 elements were generated, S4R element type was used when calculated using the finite element software ABAQUS 6.9.
CASE 3 : the Noise Experimental noise is another important issue that could affect the successful implementation of the prediction algorithm.

Fine sediment movement not only subjects to the control of flow condition, bioturbation, but also depends largely on the sediment itself geometric, physical and chemical properties(such as particle size, shape, pore water, mineral components, etc.), these result a big difference of motion compared to non-viscous coarse sediment.
During 1968~1983, Partheniades, Kennedy et al. studied the equilibrium concentrationand the affecting factors.
JingjingZhou, YangYang et al. [11-15]studied different factors impacting hydrodynamic settling velocity of cohesive fine sediment, the best flocculation particle size as well as the impact of the balance of sediment concentration, established empiricalformula of hydrodynamic settling velocity.
However, the sample collection and transport always change the sediment properties more or less.
In addition, the accuracy of the results is also affected by the experimental water samples and the equipment performance.

The results show that the liquid zinc has a strong corrosive effect on the material of sink roll bearing and shaft sleeve; The high temperature environment has a great influence on the properties of the material of the sink roll bearing pair.
In addition, zinc slag will be produced in the zinc bath, which not only affects the quality of zinc plating on the surface of strip steel, but also enters into the contact surface between bearing and shaft sleeve, forming abrasive wear and aggravating the failure of bearing materials [1].
Alloy A and alloy B are less affected by temperature than 316L stainless steel at high temperature (480 ℃).There is no direct correlation between friction coefficient and wear amount.

It is well known that heat transfer coefficient during the forced convection in the tubes, in addition to thermal conductivity, is also affected by liquid properties such as viscosity, density and specific heat, and on the other hand, the geometry of the system, i.e. the diameter and the length of the tube, and the average velocity of the fluid.
So far obtained experience with nanofluids indicate that there are other factors than those already mentioned, the affect heat transfer coefficient during the flow in the tubes like: concentration of the nanoparticles, their size (distribution) and the material from which they are made, the method of preparation of nanoparticles and nanofluids, pH and zeta potential of nanofluids as well as the method of heating of the measuring section (electric heating can affect the migration of nanoparticles are likely to carry electrical charge).
Nanofluids were prepared by use of a two-step method with using of ultrasonic bath and mechanical mixer.
