Based on CT scan data, relatively accurate model of femur for finite
element analysis (FEA) were obtained.
A patient with left leg at higher amputated position provided the resource of CT data of residual femur, which was shown in Fig.1.
The data were given in the DICOM format and can be transfered into the CAD software.
Maximal stress of new type of implant was 207.00MPa and that of one-part implant was 240.98MPa, and maximal perpendicular Fig.1 CT scan data Acetabulum Fig. 2 Improved design of osteointegrated implant a:CAD model b: FE model distal part lag part femur Fig.3 model of the assembly deformation was 0.0918cm and 0.0682cm, with the reduction of 14.51% for the former and 25.7% for the latter.
Furthermore, the reduction of peak stress promoted with the increasing of loads, which is sharp under abnormal loads.

The silicone rubber foam is a suitable material used for heat insulation and vibration reduction.
Then, the regression analysis of predicted data estimated is introduced by the extreme value distribution.
Fig. 2 Silicone foam pad compression test data regression analysis A total of 16 sets of pad compression test data parameter fitting results are shown in Table 1, and all the parameters of the interval and standard variance analysis results are given.
Observing of the figure, data distribution was significantly skewed distribution, an extreme value distribution for a typical skewed distribution is applied to fit the data.
With random statistical analysis, it founds that the extreme value distribution fit the predictive statistical data well.

These
particular conditions were considered to be related to the finish hot rolling temperature and thus the
roll cooling penetration depth imposed on the steel strip, the finishing reduction degree and
especially the strain rate conditions.
The existence of this layer of very small ferrite grains can be explained on the basis of texture analysis and calculations based on literature data.
From the dilatometric data, the critical temperatures of the ELC steel were developed through a variation of the cooling rate, combined with a preceding hot deformation treatment.
However, these conditions are hardly to occur in industrial practice as finishing rolling reductions are low and the strain rates relatively high.

Because these models for steel bars are well-established, they serve as convenient data to define the bond behaviour of GFRP bars. [10]
Since several types of GFRP bars are commercially available with varying compositions and surface treatments, the interface bond of GFRP bar-concrete is complicated and quite different from that of steel reinforcement.
However, few long-term performance data are available for GFRP composites to date.
The environmental reduction factor kD depends on the location and severity of exposure conditions.
Reduction factors are higher for external exposure conditions such as bridge decks, beams, and columns.
While the bond characteristics of steel bars in concrete have been investigated extensively, such data are lacking for GFRP bars.

An important operation of the Pidgeon process is the reduction of MgO in dolime by FeSi.
The authors, using data of fluorite consumption and an emission factor, calculated a HF gas generation of 34 kg/ton Mg for one of the fuel scenarios using fluorite of 248 kg/ton Mg to catalyze the MgO reduction.
By the cooling, most of the gaseous F compounds become solid particles and remain in the waste of the MgO reduction.
Mass percent values of slag samples 1 and 2 in Table 1 were used as weights in grams to serve as input data of raw materials for FactSage simulations under conditions of 1 atmosphere pressure and temperature of 900-1400ºC and with excess air.
F vaporization rate, calculated by using F content data presented in Table 2 and Eq. 1, are also listed in Table 2

In this paper, evidence theory is proposed as an alternative to the classical probability theory to handle the imprecise data situation.
Recently, evidence theory has become a focal point of research in international academic, and is widely used in uncertainty reasoning, target identification, fault diagnosis and data fusion [3,4,5,6].
In fact, data in the case (a) can be regarded as a special case of data in the case (b) when the uncertain parameter is taken a single value.
Evidence theory can represent many types of uncertain data, and it has good compatibility with probability theory, so evidence theory has the potential to handle epistemic uncertainty quantization.
