The analysis of variance (ANOVA) is to investigate which process parameters significantly affect the process response.
Results of ANOVA (Table 5) indicate that percent reduction is the most significant process parameters for affecting the multiple process responses.

The signal and noise properties in tomograms have been measured with quantitative phantoms and the measurement results are found to conform well to the theoretical models.
The fill factor, fractional area of the photo-sensitive region in a pixel, is as high as 79 [%] in spite of the small pixel size of 50 [µm].
The predicted MTF curve (solid line) is also shown to account for the physical parameters affecting the system MTF.
The most significantly affecting parameter is the detector MTF (dotted line).
The total system MTF is affected by various physical parameters such as the focal spot size, the magnification ratio, the reconstruction algorithm, and the detector resolving power.

Following recent initial measurements of the mechanical properties of carbon nanotubes, a flurry of activity is now emerging regarding their incorporation into polymer matrices [4-8].
The orientational torque is described as a physical phenomenon resulting from the interaction between an applied electric field and induced dipole moments due to the shape factors of the MWCNTs.
Dielectric properties of nanocomposites.
Some insights into the way that the external electric fields affect the dielectric properties of nanocomposites may be obtained by examining the variation of permittivity (ε) , and loss tangent (tan δ).

Tibia bone sample constraints combined with the unraveling of the ligament knot were identified as primary factors for low pull-out loads for the porcine ligament tests.
A composite of PLLA and βTCP is postulated to have different properties than pure PLLA.
An ideal ACL anchor will maintain its properties for the first six months after implantation; begin to degrade after 6 months; and fully degrade or contain insignificant trace amounts after approximately 12 months.
Factors that may affect degradation include: specific implant material used, implant geometry, site of implantation, sterilisation method and crystallinity [10].
The differing location may have adversely affected the results.

In addition, few factors that assist to improve productivity of ductile machining of brittle material have been discussed.
Besides the material properties, the tool sharpness in ultra precision diamond machining is very important for ductile mode machining[11,12].
It is noted that the brittle to ductile transition is affected by cutting edge radii.
High frequency vibration with small amplitude on the cutting tool affects the tool-workpiece and tool-chip interfaces.
Diffusion wear will be predominant and it will affect the rake face when cutting tool undergoes such conditions.

This alloy has several properties superior to those of Ti–6A1–4V, such as higher tensile and fatigue strength, better heat treatability, superior mechanical properties and a lower superplastic formability temperature [6,7].
The high temperature deformation of metal is a thermal activation process, which is affected by the deformation temperature, strain rate and other factors.

Introduction Successful paper feed is the main factor affects the copy velocity and this problem also exists in media transfer system such as fax, ATMs, Film developed machines etc.
Yue Wang [3] studies the property of rubber material in elastic resilience, friction coefficient and abrasion resistance.
Fully understanding the property of rubber material using in roller is another aspect to improve the efficiency of paper feed unit.
Most prior papers dealing with the paper feed unit problem focus on the paper property, however, they do not pay attention on the mechanical property, which is very important in the study of the successful and high-speed paper feed.

The tool wear experiment was proposed in single-factor method, the effects of water vapor and ionized air on tool wear with the change of milling speed (vc) , so the depth of cut(ap), width of cut(ae) , and feed per tooth (fz) were maintained as constant, just change the cutting speed (vc).

One of the important factors that influence the slow crack growth and thus the lifetime of the pipe are the residual stresses present in the pipe.
These properties, together with the fact, that residual stresses have the tendency to maintain their magnitude for a very long time [4], make residual stress an important factor, when it comes to service lifetime.
There’s axial residual stress too and it affects the tangential residual stress, making the magnitude higher, but this effect takes place only in longer pipes.
It was recommended to multiply the values of ΔD by a factor of (1 + µF), where F is a correction function.
