The simplified Bishop method uses GeoSLP1 software to calculate, and the strength reduction finite element method uses ABAQUS 6.10 software to calculate.
When using strength reduction finite element method, elastic modulus of soil is valued as 200MPa, Poisson's ratio is valued as 0.3.
The calculated stability factors using formula (1), formula (2), simplified Bishop method and strength reduction finite element method were recorded as F1, F2, F3 and F4.
(2) Simplified Bishop method and strength reduction finite element method can be checked each other because stability factors obtained by the two methods.
The former is easy to grasp for the first-line technical staff as its principle is intuitively clear, the latter can obtain the potential sliding surface, the stress, strain and displacement data of slope automatically but the calculation process is complex

It involves transmission of data from a transmitter to a receiver.
In order to achieve successful data transmission, a continuous alignment between the transmitter and receiver telescope is needed.
Introduction Free-space optics (FSO) communication is a technology that uses light to transmit data through free space.
For an FSO link to successfully transmit data, it requires a continuous alignment between the transmitter and receiver [1].
Then the data are passed to controller which calculates the required external forces or displacement and send signals to control the actuators.

The BP neural network is trained with the data base to realize the intelligent diagnosis.
Table 1 Natural frequencies comparison order 1 2 3 4 5 natural frequency known data 9.1929 36.703 82.346 126.72 145.89 analysis data 1.022 30.380 39.014 96.781 153.210 After the comparative analysis, it seems that the appearance of crack in structure causes the change of local stiffness.
The crack affects the integral dynamic properties leading to the reduction of the natural frequencies [5].
Export analysis file, modify the damage position and depth, after many times operation, export 28 groups of data and obtain five natural frequencies database corresponding to different positions and depths crack.
Twenty groups of data are training samples, and another eight groups are testing samples to verify the network diagnosis ability.

The cell voltage, electrolyte temperature, and CR of these cells were reduced with the days of operation and agreed with the data published elsewhere [6, 10] and with Q-350 cells [21].
This result agrees with data published elsewhere [35], where reducing the cell instability from 0.072 to 0.063 µΩ led to an increase in the current efficiency by 2 % and a decrease in the energy consumption by 0.23 kW/kg Al [35].
Many thanks to the head of R & D and staff of production research for their continuous encouragement and supplying with some valuable data during this study.
And I had full access to all study data, take full responsibility for the accuracy of the data analysis, and have authority over manuscript preparation and decisions to submit the manuscript for publication.

As the rough set theory can fully reflect the objectivity of the data, without providing any prior knowledge other than the data information, many scholars have studied the weight determination method based on rough set theory.
Knowledge Reduction.
Knowledge reduction is the core of rough set theory.
To calculate the attribute importance of indicators in above procedure, the discrete data processing, the selection of discrete values refer to reference 5, the discrete data table is shown in table 2; then the simplified data table is shown in table 3.
Rough sets: theoretical aspects of reasoning about data.

If the LCF data is to be used to directly assess the life of a component, the crack size at the point of initiation must be known and compared to the dimensions of the critical location in the component.
If the definition of initiation results in large crack sizes before the load drop criterion is used, the data may give un-conservative life predictions for e.g. thin-walled components.
A better model response with respect to experimental data could probably be obtained by using a threshold effect in the kinematic hardening, cf. [7] or by using a Ohno-Wang type of model, e.g. cf. [8], [9].
This data agrees well with the FE-results from both elastic and elastic-plastic analyses, and is still not affected by the applied Rϵ.
This was shown to give good results, but require experimental data of sufficient quality.

The particle swarm optimization (PSO) is employed to get the optimal rolling reductions.
Some single target optimization methods for rolling reductions in introduced in reference [2-3].
The reasonable load distribution cannot only make the shape and thickness control more easily, but also decreases energy loss. 2.Rolling load distribution Load distribution of rolling mill is to identify the rolling reduction (or the outlet thickness) of each frame according to certain rolling conditions, including the original data and the requirements of the finished product specifications.
The total rolling reduction of the six frame is =26.5mm.
What’s more, the rolling reduction of the 4-th, 5-th, and 6-th frame decreases in proper order.

Individual countries defined a progressive scale for the emission reduction applied to automotive vehicles.
The authors also estimate the overall effect of the Phase 3 standard on oil savings and CO2 emission reductions.
Temperature data is recorded using an MGC data acquisition module connected to type K thermocouples.
The data is acquainted with a 1 Hz frequency.
As the vehicle moves with higher speeds, heat transfer increases, leading to a temperature reduction.

From 2001 to 2010, there was no significant difference of CH4 emissions per unit area between the cities, all CH4 emissions reduction was mainly due to a reduction of rice growing area.
After searching and screening, get in line with the requirements of the research on data integration [3-11], which contained the CH4 emission data of 51, distributed in 7 test points.
Experimental treatment of CH4 emission from rice data including: water management style, applied or not applied straw, the test set of different water management measures.
In this study, the rice average CH4 emissions and per unit area of the foundation data were calculated for the study area CH4 fluxes.
In 2001-2010, there are rice planting area and area reduction ratio in south Jiangsu area ( Tab. 1 ).

The data acquisition is performed with a CMM and a self-centering technique to measure conical sockets manufactured in the faces of pattern artifacts.
· Data acquisition to determine the model using pattern artifacts and measuring them
Data acquisition Spheres are typically used to materialize, through its center, a single point in space.
In a process optimization [7] the coefficients of the polynomial error functions are varied until the measured data and the modeled data match.
