Kraemer [2] probed into the vibration sources by the field test data.
Response Theory Analysis Environment vibration spreads through soil around to the base of the machine or its located building, and eventually reaches the ultra-precision machine leading to the accuracy reduction.
Data from the table tells that the vertical vibration effects more, with the maximum displacement close to 40 μm, as has greatly exceeded the requirements of precision machining of 50nm.
Therefore, it is extremely important to consider the suitable vibration isolation and reduction in the view of optimize processing environment or the machine structure to decrease the adverse effect, ensuring the processing precision consequently.

Based on the TEM data the clustered method was proposed for calculating the electronic phase transitions.
The calculated data obtained by solving the system of equations by UHF method, are used for construction of "Muffin-Tin" (MT) potential clusters [9].
The origin of the ferromagnetic phase appearance in the samples of Ni51Ti49 alloy is the displacement of atoms caused by plastic deformation which leads to the reduction of the crystal lattice symmetry and appearance of the icosahedral clusters with the Frank-Kasper structure. 3.
The reduction of the crystal lattice symmetry leads to uncompensated magnetic moment in neighboring clusters and, as a result, the ferromagnetism appears. 4.

Hence, the overall performance of PV panel will increase with reduction in humidity level [1].
These data produces a relative error less than 4% [2].
This is suitable for certain level of relative humidity reduction, but when the relative humidity was further reduced to 29%, the corresponding PV cell efficiency was decreased to 2.37% [6].
The experimental data was measured in December 2013, and January 2014.

Recently, the triple phase boundary (TPB) located at the contact point of oxide, electrode and ambient atmosphere, has been indicated as the only place of the localized reduction and release of oxygen during both, electroforming and filamentary RS [6].
Results and Discussion According to the obtained XRD data and SEM images (Fig. 1. b), the as-grown YMO film is of nanocrystalline, hexagonal phase (International Centre for Diffraction Data, JCPDF 25-1079).
It is expected that the nanoscale reduction concerns the B-site cations, however it remains unclear whether it involves possibly present Mn4+ or Mn3+, or both.

The advantages of having medical images in the digital format are: the good resolution; to be able to quickly find and make them instantly available to the physician, enabling the comparison with other images of the patient; ease in the process of details enhancement; risk reduction of image loss or damage over time; possibility to make copies without much quality loss; editing and publishing quickly and with a low cost, either in digital or printed media [6-11] because analog x-ray film uses silver in the composition [12].
At each stage of the simulator it was performed the acquisition of 5 random points and their average calculated, after obtaining the average of the points of the analog and digital images it was applied a data normalization technique which allowed the generation of graphics of each procedure.
An ANOVA (1 criterion) statistic test, Fisher test, was conduct in the results to compare more than two samples whose data must be measured in “in-between” journey.
Conclusion In addition to the advantages of having medical images in the digital format listed in the references such as: better resolution; quickly find and make them instantly available to the physician, enabling the comparison with other images of the patient; ease in the process of enhancement details; risk reduction of image loss or damage over time; possibility to make copies without much quality loss; editing and publishing quickly and low cost [6-11], this research shows that digital images have better spatial resolution and better contrast.

Body diode has also been widely recognized and utilized as free-wheeling diode instead of SBD to realize cost reduction and shrinkage of the systems comprising of the SiC power devices.
Typical one chip data were plotted for each condition in the following Figs. 3-6 since all measured samples showed the same trend.
The data of Figs. 5 are replotted from the view of the temperature dependence.
Generally, more forward current flows at high temperature than at room temperature due to two effects:(i) the increase of the carrier density (particularly, minority carrier density) and (ii) the reduction of forward voltage (VF) derived from the suppression of the potential barrier.

From these data an increase
of the yield from 87% to 92% can be observed as the growth rate
increases.
From these data an electrical defect density of 22.2 /cm2 has been obtained for the standard process with silane.
further reduction of this density to 5 /cm2 has been obtained.
This reduction of the defects density and the possibility of growing at high grow rate gives the opportunity of manufacturing large devices that can carry high current in forward bias and that can have very high breakdown voltage.

The system mainly includes two-stage reduction gear, screw, nut, and fork-lever driven by a servo motor with a controller.
The two-stage reduction gear is formed by a double cylindrical gear and two cylindrical gears.
An equivalent family of plant transfer functions of the system can be analytically, numerically from the system model or directly from experimental input-output data obtained from the real system [10],[11].
Additional external reference signal can be applied to the feedback connection of positioning mechanism to provide sufficient excitation while gathering data for identification.

However, because of the problems such as compatibility of data, when the outer data is loading, the model is too complicated to omit the unrecognized features, and the model may fracture and the substance may be lost.
The principle of topology optimization is to minimize the structural compliance under the condition of meeting structural volume reduction.
The volume function VOLUME is defined as the constraint function, and the volume reduction is set as 40%.
