The redial stiffness of the bearings was found according to bearing specifications presented in Table 2, by using the following experiential formula [4]: (8) Where CA is empirical data defined based on the experimental results.
In design optimization, the DOE can be used to fit the simulated response data to mathematical equations.
A grid of data arguments of minimum density through the multivariable design planetary is often used instead.
The predicted three candidates’ points are summarized in Table 4 by comparing to its original data.
It can be seen that when minimizes the structural weigh Mw the FONF has been increased as result of inertia forces effects reduction.

l Automatic acquisition and storage of data.
l Security administration of data & system.
Massive data can be used for common prediction due to the wide range of Logistics.
The user can either input add, cancel, refresh and search for data available in data base with the aid of data base management system, or process data by system user interface then save data operation simultaneously in data base while reentering is necessary if there is no relevant data for new project.
LMIS has not only reduced data processing workload of system user but also guaranteed the uniformity of data used for prediction by pre-processing and analyzing original data assisted by data mining technology.

MMX technology adds eight 64-bit registers (MM0-MM7) of 57 new instructions in the processor, a plurality of 8/16/32 bit integer data integration into a 64-bit data.
IF input intermediate frequency sampling data, the local carrier and local pseudo-code, are 8 bit quantitative data.
Therefore, this article USES the method is that before the eight multiplication, the extension of the 8 bits of data into 16 the sign bit, concrete is before 8 bits of data to add 8 0 or 1, the same as the data of the sign bit, as shown in table 1.Data expanded, although the wasted storage space, but guarantee the application and multiplication of 16 multiplication instructions after only low 16-bit result does not overflow.
Table 1 8-bit signed extended to 16 High 8 Low 8 With the same sign sample data After expansion in Table 1, the multiplication of inputs A, B are into 16 data, MMX registers 64, each register can be loaded into the four sampled data; sampled data bit actual calculation of the number of CNT.
Because 16-bit 32-bit multiplication result, only keep a low 16 results also removes unwanted high 16 data.

Since Co is a 3d fast diffuser transition metal, its introduction in the production line creates a potential risk of cross contamination with possible subsequent yield reduction.
The literature datum of a cobalt-related electron trap [3] is also shown for a comparison, and it is observed that the peak E1 in Fig. 1 reasonably corresponds to the extrapolation of the data.
However, the emission rate data we obtained are very scattered, suggesting the presence of more levels, maybe a band of levels which we cannot correctly separate from the two main levels.
Finally, from an extrapolation of the SPV response a practical LLD can be estimated from data plotted in Fig. 6.
This study has highlighted the strong reduction in Ldiff caused by Cobalt contamination that can be observed on both p-type and ntype silicon wafers.

The throughput of the data transmission is proportional to the modulation index M, thus, a single objective fitness function fthroughput can be expressed as where Mmax and Mmin are the maximum and minimum values of M, respectively.
The Single Objective Fitness Function for the Interference Reduction.
We firstly measured a frequency spectrum of [250 MHz, 260 MHz] bands at the top of a mountain in Yongin city, Korea, and then, used the measured data as the input of the simulator.
When all weight values are non-zero and the weight value w1 is the largest, the scenario can be regarded as ‘multimedia service mode’ where the SU needs to transmit data using a wide vacant band.

The data show that the surface energy of the dielectric after the repair process strongly depends on the process conditions like OMCTS flow, substrate temperature and choice of additives.
The surface energy data not only give information about the effectiveness of the repair process but can mainly be used to predict whether or not the material shows a good wettability.
Fig. 2: Dispersive, polar and total surface energies of the low-k dielectric in pristine condition, after etching and after application of different repair processes Fig. 3: Differences in total surface energies of the dielectric after repair and the studied cleaning solutions The data show that in most cases large energy differences occur, especially if solution C is applied on the dielectric after a repair process which distinctly lowered the polar energy contribution.
An effective repair process leads to a decrease of the polar energy part of the solid and a reduction of the total surface energy.

This article should collect 30 frames noise reduction image with no fault, then average process for the 30 frames image, and finally we can get a frame standard image.
In this paper, the acquisition of image is based on VC++ and transmits data using on-line network interface, and design the foundation platform,through the combination of flexibility in C++ and MFC wrapper class [3].
Then, collect image data and process data to display in interface.

We made test pieces using sandblasting under several conditions, and surveyed the roughness of the surface and the reduction of sphericity caused by the process.
The top-left one is a cylindrical gauge, which is used to check the diameter and cylindricity calculated from measurement data in large volume.
The top-right one is a concentric truncated cone gauge, which is used to check the concentricity of each cone and cone angle from the measurement data.
The bottom-right one is a cylindrical step with round corner, which is used to check the corner radius fitted to the measurement data with optical digitizers.
