The reduction of the peaks during the ageing after annealing is more noticeable in quenched specimens than in air cooled ones, and in furnace cooled specimens the reduction is even smaller, indicating that the process is really an ageing phenomenon.
The low frequency Z-peak height is not measured in the case of the FeSi-7 sample because the frequency at which the maximum is reached is not a reliable data.

Reductions in traction-energy consumption contribute to direct energy-cost saving.
Based on specific exposures to emissions [84] provides country-specific data for emitted pollutants where average values have been used.
As it aids in the reduction of carbon emissions, the technology is intended to contribute to environmental causes.

Based on the structural geology, sedimentology, palaeontology and geochemistry, the sedimentary facies and evolution patterns are developed in Songnan area from the studies of seismic data, cores, well logs, palaeontology and geochemistry.
With the increasing number of wells and improved quality of seismic data, oil and gas resources have been found in fault basins in recent years[8-9].
On the basis of former researches and according to the interpretation of well logging, lithology and seismic data, this paper studies the sedimentary evolution of the fault depressions in Songnan area in detail combined with paleontological data and holds that the buried depth of the study area is great and the sediment strata are thick, which have good source-reservoir-cap assemblage. 1 Regional geological conditions Songnan area is located in the east of Inner Mongolia Autonomous Region, transversely placed at the crossing of Liaoning province, Jilin province and Inner Mongolia Autonomous Region.
Shahai Formation also contains sporo-pollen, ostracoda fossils and plant-derived fragments. 3.4 The sedimentary period of Fuxin Formation The bounding faults activity decreased at this sedimentary period, leading to the reduction in water depth and slope gradient at the edge of the basin.

The obtained data then analyzed using statistics (analysis of variance).
Introduction Production process used often robot to produce high quality products, reduction production cost, shortening processing time and to simplify the process.
Object data was retrieved and then processed using statistics so that it will show a pattern of certain comparisons that can be connected aiming to determine the magnitude of the force that occurs with mechanical holder provide power variation in actuator ​​of NiTi SM495.
Results And Discussion Data obtained from the experiments and measurements can be arranged in following tables Table 3.2 Variation of electrical power to a grip force for the spring constant 0.14 N/mm.
Conclusion The conclusion based on the experimental results in the effect of power variation on SM495 NiTi actuator to the grip force of gripper, and the analysis of experimental data that has been described.

The model is based on 4H-SiC physical and material properties and is validated by high temperature 4H-SiC lateral JFET data, fabricated and characterised by our group at Newcastle University.
Next, the validation of these model parameters using the data from 4H-SiC lateral JFET is presented.
EgT=Eg0-α T2T+β (1) High doping concentration causes a reduction in the bandgap of the semiconductor.
This data is illustrated in Fig. 1(a), along with the best fit of the Aurora doping dependent mobility model.
Overall, the simulated results show excellent agreement with the measured data; highlighting precise calculation of threshold voltage and drain saturation currents.

Based on analysis results of measurement data, comfortable thermal environments for arcaded pedestrian paces in the pedestrian streets of the Lingnan region were understood.
A round of field data measurement for five measurement points was required to be completed within one hour.
As can be seen from Fig. 6, points A3 and A5 each have two data where the globe temperature is higher than the air temperature.
It is discerned from the original recorded data that, these two abnormal data of point A3 were measured at 12:30 and 14:30 respectively.
It is thus clear that the abnormal data of points A3 and A5 are related to intense solar radiation at noon.

To single frequency vibration acceleration at collected experimental data is analyzed, then based on the experiment selected the sensitivity of acceleration sensor, charge amplifier and output gain and filtering the gain of amplifier circuit, and finally determine the acceleration deviation E actual theory domain for (0.8 V, 0.8 V).
Test results When air spring initial height is 9.5 inches, Corresponding reform of the experimental data processing can be controlled before and after single frequency excitation, vertical acceleration root mean square value of sprung mass and the peak vertical acceleration of sprung mass, as shown in table 1.
Table 1 Comparison of experimental results under single frequency excitation Peak value of sprung mass acceleration in vertical vibration(m/s2) frequency 1.5Hz 4Hz 6Hz 7Hz 8Hz Control before 0.8052 0.3204 0.3395 0.3969 0.4323 Control later 0.6169 0.1984 0.3410 0.2513 0.3348 Can be seen from table 1, in the 1.5 Hz silent resonance and 4 ~ 8 Hz vibration frequency range, through the air spring after the electronic control unit to control the vertical acceleration of sprung mass has a different degree before the control is reduced, to facilitate control of vibration reduction effect is superior to exert control.

The Poisson’s equation may be solved by different mathematical methods: minimization of a certain specially selected functional [4]; assignment of boundary conditions by three directions; reduction of equation (1) to solving three one-dimensional differential equations.
Preference should be given to the grid regular topology and elements in the form of hexahedrons. 3D geo-seepage model is calibrated basing on the field observations data (read-outs of piezometers, drainage flows, etc.).
The updated seepage coefficients of separate geological features and grout curtain are computed basing on the obtained data (Fig. 2).
