Reduction of average crystallite size of dispersed maghemite particles was observed
after encapsulation process.
The reduction of the magnetization is basically due to the present of the silica that causes an increase of total weight of the system.
The particle size distribution is between 1 and 9nm with an average diameter of 4.98nm (data not shown) Fig. 3(b) shows TEM micrograph (BF) for TF1.

It allows to analyze of motor parameters using both on-board diagnostic system, and data network CAN BUS under different operating conditions of the system.
Parameters comparison for: a) injection system, b) ignition system The values of these parameters during testing are continuously monitored and measured by sensors and then sent in the form of signal to the ECU engine, where they are read by on-board diagnostic OBDII device or on-board data network CAN BUS.
The proces acceleration in gear 5, the input parameters for the simulation According to the accepted assumption process of the acceleration was analyzed with different degrees of reduction of the final value of the accelerator pedal deflection.
Change of the accelerator pedal deflection limits to the value of 50% results in a reduction of the fuel injection time.

The data-weighted averaging (DWA) algorithm can reduce static current source mismatch effects, but it increases the effects of glitch energy.
This is because the TC switching scheme produces a data-dependent output signal.
By implementing the OES switching scheme, the output signal is indirectly changed from data-dependent to clock-dependent.

Studies produced baseline data but needed to be adequate regarding the implications of hydrologic processes to flooding.
This data was integrated into the attribute table of the sub-catchments vector layer.
The collected data were consolidated for comprehensive assessment of the river basin.
The consolidated data was tabulated in Table 6 using the morphometric ranking method.
Moreover, a combination of other relevant data of the drainage basin, like climate, rainfall data, and soil type, in flash flood vulnerability assessment can also be undertaken, as these are also essential factors contributing to an area's risk to flash flood.

Fig. 3a illustrates the
reduction of grain size with the increase of refiner additions, from which it can be seen: (i) Al3Ti is
less effective than Ca and Al4C3 based refiners on grain refinement for magnesium and (ii) the grain
size decreases with the increase of refiner additions, however, it reaches a stable level when the
refiner addition increases to a certain amount ( 0.3% for Ca and Al3Ti and 0.5% for Al4C3,
respectively), and the excess of refiner addition does not cause further reduction of grain size.
Annealing of as-extruded and as-rolled a b c a b 50µm 50µm 100µm 100µm 100µm a b specimens results in increase of ductility and slight reduction of ultimate and yield strength.
The data of tensile properties of the specimens annealed at 250°C are also listed in Table 1.

Loads and displacements were recorded by the automatic data acquisition system.
The comparisons and the ductility ratios in Table 3 show that an increase in the diameter and number of the longitudinal steel bar causes a larger degradation of strength after the peak strength, hence a reduction of ductility of the specimen.
No improvement in ductility is shown in Figure 4(f), and in fact the ductility ratios in Table 3 show a reduction in B8 by providing perforation.
This is because specimen B7 with stirrups was already very ductile and the perforation did not further increase the ultimate strain while it increases the softness of the block and hence the yield strain, therefore, resulting in a reduction in the ductility ratio of B8.

Reachable matrix
Hierarchical processing the reduction matrix of the reachable matrix
1) Removing the elements having a strong connection relation (the elements with identical rows and columns in M [6]), S6 in {S2, S6}, get (L).
2) According to how many "1" in each line in M’, we order the element in less to more, adjust the columns and rows, make elements of main diagonal the zero, then get(L) (Fig.3).
3) In (L), from the upper left to lower right corner, we decompose to get the largest number unit matrix in order and put in box, each box represents a layer [6, 9].
In the reduction of accessible matrix, we rule out the S6 element which is strongly connected to the element S2, so it belongs to and the third layer.
Fig. 3.The reduction matrix hierarchy chart Drawing the multilevel hierarchical directed graph Arrangement all the factors according to the existing level, then draw a arc of direct contact between the elements of different layer according to the left "1" element after removal unit matrix after in (L) [10] (Fig.4).
Consulting company need a long-term data collection of these factors, and analysis and forecast their development trend.

Introduction
The body-in-white (BIW) structural parts and panels, and in particular the materials used in its construction, offer the greatest possibilities in terms of weight reduction and determine the behavior of the car in the event of collisions.
The stress drop was observed and the magnitude appeared is increased with decreasing the pulse period when the Fig. 4 Joule heat induced temperature (FEM calculation) and flow stress reduction (experiment [8]) pulse duration is constant, as shown in Fig. 3(a) and 3(c).
As is evident from this data, the flow stress reductions during electro-pulsing tensile tests are beyond that of the elevated temperature tensile tests.

Abstract.
The huge reduction of media switching field, Hsw, obtains from exchanged coupling between soft and hard magnetic phases, Aex [8, 9].
The reduction of Hsw with lower Ku of L10-FePt materials The L10-FePt/Fe based ECC bilayer granular media is investigated in this section.
The reduction of Hsw with higher Ms of L10-FePt materials Fig. 4 shows the effect of Aex with various Ms of L10-FePt on normalized Hsw (Hsw is divided by Hsw of single layer at Ms of 0.1 MA/m).

It can be concluded that the reduction in beam rigidity will cause the reduction in the first three natural vibration frequency and lengthen the natural period of viberation.
In all the response of displacement and internal force above mentioned, the maximum data can be extracted to be shown in Table 2.
Some conclusions are be drawn as follows: 1) For the whole pile-soil-bridge structure , the rigidity reduction in beam will reduce the first three natural vibration frequency and lengthen the natural period of viberation.
