This paper presents a novel and effective characterization method for giant piezoresistive properties of silicon nanowires by using the reference structures.
These experiments need to simultaneously measure the stress of the silicon nanowire and its change rate of resistance, and the experimental apparatus is complicated, and easily affected by many factors.
The simulations show that the stress propagation into the overhang region is significant, which numerically reveals that the undercut inevitably affects the mechanical resonant characteristics of the silicon nanowire. .

Previously, human factors was left behind and be considered as independent factors with very less contribution to the overall system performance[1].
Researchers conducted their studies on individual variable to measure performance, factors affecting performance and effect of performance; either on individual level or organizational level.
Most of them relate one or two variables or factors affecting performance with the effect or consequences of the level of performance.

The width of the Kerf and surface roughness are the most factors which needs for focusing during cutting process for various plate cutting operation by CNC machine.
Its concluded from our result, that the characteristics of the main selecting factors which effects the laser machine performance such as, the focal lens nozzle height (0.6 to 1.0mm) and the ability and speed of cutting should be fixed and not changing.
However, heat may transfer to the material and affects adversely the cutting quality and accuracy.
Improving the properties of laser cutting can achived by several steps like cleanliness of the lens, correction of the focal path as well as the ability of high and constant cutting will gives high cleanliness without impact on the surface of the cut.

Physical properties test by x-ray diffraction (XRD) and fourier transform infrared (FTIR) shows highly crystalline of CNF which indicates improvements the mechanical properties of PVA/CNF nanocomposite film.
The aspect ratio is the ratio between the size of length (L) and diameter (D) of the CNF which is an important factor to mechanical properties of CNF as reinforcement in matrix.
The unhomogeneous of the CNF in PVA will result non-optimum mechanical properties of PVA/CNF nanocomposite film.
That causes the mechanical properties of PVA / CNF nanocomposite films was increased.

Model of DC Motor.The equation of DC motor electrical part can be described as Eq.1: (1) where, i(t),ω(t),ua(t) are the current,angular velocity, and applied voltage, respectively.ke is the emf constant, depends on certain physical properties of the motor.
The mechanical part of the motor equations is derived using Newton's law, which states that the inertial load J times the derivative of angular rate equals the sum of all the torques τL & τe about the motor shaft.
Fig.1 Model of DC Motor (2) where km, the armature constant, is related to physical properties of the motor, such as magnetic field strength, the number of turns of wire around the conductor coil, and so on.
The torque τe seen at the shaft of the motor is proportional to the current i(t) induced by the applied voltage ua(t),J is the inertial load.kf is the torque damping coefficient caused by all factors such as loads, it is a linear approximation for viscous friction.
However, as a dynamic control object, multiple factors affect the performance of motor, such as structure, material, load, and other factors.

The rheological properties of chocolate were tested by Anton paar modular compact Eheometer: MCR 502 for analyzing flow behavior.
Mechanical platform.
Moreover, based on its pseudoplastic property, thermal change during machine processing also affected the size of the chocolate line.
Therefore, three fundamental variables and mechanical properties of the material were considered in this work to yield a constant width of the chocolate line.

As much as possible essential changes in properties of materials can be gained at use of physical tools which provide simultaneously many factors of action on a material.
As a result of complex affecting the phase transition in metals and graphite and considerable crushing of structural elements is detected.
These neither mechanical nor hydrodynamical factors of SDP have essential influence on a situation inside a metal barrier. 4.
Very small volume concentration of reinforcing elements, however, leads to essential changes of mechanical properties.
Thus, it is not possible to find connection between volume changes of "channel" zones in structure and level of mechanical properties.

Introduction The failure of the stator insulation in rotating machines is closely related to the properties of its component materials.
These material properties are affected by exposure to a combination of thermal, electrical, mechanical and environmental stresses during operation.
Deterioration will occur in insulation that has voids created by electrical and mechanical stress.
Tip-up dissipation factor (∆tan�) is the differences between measurements at 2 kV and at 6.6 kV.
∆tan� indicates increase of dissipation factor due to applied voltage.

The mechanical behavior; in particular fatigue properties of cast aluminum components are affected due to presence of these defects [9].
However a number of factors are responsible for porosity formation in modified alloys.
