Virtual methods to assess the fitting of a fracture fixation plate were proposed recently, however with limitations such as simplified fit criteria or manual data processing.
However, data collection were performed manually, which requires long processing time and has higher possibility for error by the operator.
By automating the process, accurate and speedy data collection is possible.
Therefore, more time could be spent for extended data analysis to provide further information on an implant's fitting based on quantitative measures.
Second, to investigate the extent of borderline fitting cases for a tibia plate by performing extended analysis on the data collected based on the automated fitting method.

The results of analysis agree well with the experimental data, and the motion of the displacement adjusting mechanism is analyzed accurately.
The paper focuses on the coupled analysis methods for variable displacement vane pump, and compared the results with experimental data.
Fig. 5 shows an oil pump performance test platform, the rotation speed and outlet pressure can be adjusted independently during the test, and the experimental data including the flow rate, torque and oil temperature are recorded.
From the data in the table 1, simulation and experiment results agree well at low speed with relatively low outlet pressure.
The simulation results are consistent with the experimental data and reasonably reflect the vibration of the adjusting mechanism.

Our data indicated that multi-antibacterial polyamide fibers have excellent antibacterial effect, good far-infrared emission and the negative oxygen ions emission features, while have little affect on polyamide fibers’ structure properties.
Fig.3 Energy spectrum of the particulate in the 2% addition polyamide fiber Tab.1 X-ray diffraction data of polyamide fibers X-ray Diffraction Analysis.
We can see from the data that adding multi-bacterial master batch makes little change to polyamide fibers’ melting temperature, just a little wave.
However, with the increase of addition multi-bacterial master batch, the melting enthalpy Delta H declines first, but when the addition ratio is 2%, the data increases significantly.

In this work, using our earlier published creep data for advanced creep-resistant T23 and P92 steels, the interrelationship between creep deformation and damage have been analysed by linking them to the identified acting mechanisms, in terms of empirical formulas for the fracture time assessment.
These values correspond to published data on the creep behaviour of precipitation strengthened steels [1,5].
The analyses of creep data indicate that creep behaviour of the steels under investigation obey both Monkman-Grant and modified Monkman-Grant empirical formulas.
This means a substantial reduction of testing time.
Summary The analyses of creep data of a low-alloy T23 steel and a tungsten modified P92 chromium ferritic steel indicate that the creep deformation and fracture are mutually linked and controlled by the same mechanisms.

For verifying the tendency of data series, monotony trend, namely Kendall inclination, should be calculating:
Data series of annual precipitation and 5-year-moving –average precipitation were listed in Fig. 1.
Further mathematical analysis in Table 1 shown that data series of annual precipitation fell short of normal distribution, and the deviation coefficient was 0.54, thus, Mann-Keddall method is suitable in this study.
Monthly precipitation data in Fig.2, Table 2 and 3 shown that most rain fell between March and August,the rainfall in these month was about 70% of the annual rainfall.

N is the number of data points.
This caused the colour reduction of POME to be low.
In contrast, there was only 78% COD reduction for EC stand-alone process.
The combined EC-AD process showed 98.33%, 98.37% and 100% reduction of COD, colour and turbidity, respectively.
The EC stand-alone process only showed 62.33%, 72.79% and 74.43% reduction of COD, colour and turbidity, respectively.

During Stage II, the development of cracks produces progressive load drops such that the response curves present an uneven behavior, with a reduction of stiffness.
Stress-strain results of tensile tests: a) basalt textile grid; b) BFRCM strips The post-treatment of the experimental data allowed the definition of the peak loads (FI, FII, FIII), the peak stresses (σI, σII, σIII) and the corresponding strains (εI, εII, εIII) related to the three characteristic points at end of each stage, for the three series of samples.
These values were always lower compared to the value obtained from three point bending tests on the mortar (7.2 MPa), with a reduction of 49%, 42% and 46% for SP_1L, SP_2L and SP-3L series respectively.
This reduction was mainly related to fibre-to-matrix slipping phenomena, underlined by DIC analyses showed in the following.
Indeed, the presence of rovings in the transversal direction implied a local reduction of the mortar cross-section with unavoidable consequent reduction of its resistance.
