The lattice friction stress is known to depend on deformation temperature, but as far as the authors know, experimental data are not obtained yet.
Table 1 Material data used in the analyses temperature dependence of the lattice friction is assumed to be the same to that of the hardeness data.
Table 1 summarizes material data used in this study.
Comparison of data shows that shallower trench results in higher density of dislocations.
Results showed that reduction of gate length and trench depth both caused an increase of dislocation density.

The comparison of experimental and calculated data has been conducted.
However, the application of stochastic method requires numerous experimental data.
The authors suggested a block model of heat and moisture transfer on the bases of the obtained data.
Figure 3.Timber heating Final calculated data of each period is assigned to the initial data of the second period.
The satisfactory convergence between mathematical calculations and experimental data is described.

Box 87, Helwan, Cairo, Egypt E-mail: waleeddaush@cmrdi.sci.eg Keywords: Powder metallurgy, soft magnetic materials, Fe-Co solid Solution, chemical reduction Abstract A nanosized cobalt-based alloy containing 20 wt % Fe was synthesis by electroless chemical reduction method using alkaline tartarate bath and sodium hypophosphite as a reducing agent .
In particular, granular materials consisting of nanosized cluster soft magnetic metal embedded in a non-magnetic metallic matrix have potential applications as media for data storage.
From the phosphorus content determinations by spectrophotometry of the investigated powder was 2.5 wt% from the total alloy content meaning that the alkaline tartarate bath giving an electroless precipitate has low phosphorus content but by sintering in hydrogen atmosphere the phosphrous content decreased into 0.1 % due to the reduction of the metal phosphides to the phosogen gas which was liberated.

As a function of the exponent of the number of cycles, N, a linear reduction in residual stress was proposed by Han et al. [5] based on experimental data as follows: (1) where is the residual stress relaxation, is the residual stress at the first cycle and k is dependent on material softening and applied stress.
The proposed equations were validated against experimental data.
The values of these constants gathered from fitting the experimental data are shown in Table 2.
Eq. 7 is evidently able to account for the cold work effects and produces agrees well with the experimental data.
The estimation was found to be in good agreement with the experimental data from [7].

It is very difficult to get complete data records with all 60 attributes, many records are incomplete and it is adaptable to do attribute reduction for them.
Though the input gas data is expressed in the percent of volume, the input data is still dispersant.
The diagnosing process is described as the following: Step 1: We use the first BAM network to separate normal state from all the data set, and we get normal data set and abnormal data set.
For abnormal data set, do step 2.
For overheating data set, do step3, for discharge data set, do step 4.

Data for the nanopowders characteristics, as well as output rate and energy consumption are discussed in this paper.
Other consequence of the DPM mode is reduction of the output rate because of the roughness of the target surface.
Therefore, reduction of the on-off time ratio leads to reduction of average laser power and plainly output rate.
That leads to increasing of laser intensity in focal spot, reducing of thickness of melted material, and reduction of the energy wasted for thermal conduction.
Ability of shortening the laser pulse is limited by fore and back fronts of the pulse and reduction of laser pulse energy.

The data that are to be updated must be written to empty page of flash memory and then the original page of the data is marked as invalid.
FTL can maintain a consistent state for general data and meta-data, even though flash memory encounters an unexpected power-outage.
If erasure time of a block reach the threshold, data in the block is exchanged with the data in the block of the least erasure time in SSD.
In Li-ping Chang’s[9] algorithm, all blocks of SSD are divided into hot pool and cold pool to store hot data and cold data respectively.
Otherwise, data in the selected block will be swapped with data in the block that erasure time is least in SSD.

Based on in-situ observational data, we analyzed energy features of strong ground motion induced by short delay blasting in unsaturated loess field through three aspects of time history, frequency spectrum and attenuation.
For time histories, the data show exploding ground motion has two essential characteristics, i.e. larger peak ground acceleration (PGA) and shorter duration.
Fig. 2 shows the time-history data recorded at the centre position (UD, vertical component; SN and EW, horizontal components).
Time histories of the exploding ground motion For actual duration features of exploding ground motion, we adopted a quantitative criteria of acceleration () to analyze the time-history data as the follow
Using Eq. 2, duration features of recorded data (see Fig. 2) are summarized in Fig. 3 (the percentage representing the ratio of effective duration to duration).
