Parameters M=10,r=0.10,T=1, are firstly chosen and time period of [0,T] is divided into 100 parts with the mesh size , according to data on the clause.
The variance reduction ratios have a increase tendency as the reversion speed increases from Fig.2.
Therefore, the correlation between the control variate and the original problem is bigger and the variance reduction effect is better.
Then from Fig.3, we can see the variance reduction ratios have a little decrease tendency as the reversion mean increases.
However, the control variate algorithm also has a good variance reduction effect.

This work represents experience of modification of heavy M200 concrete on the basis of local raw materials of Yakutia, with use of polymeric impregnation of "Silor-Ultra" as a result of which data on increase in strength characteristics of material were obtained, the internal structure of the modified concrete was investigated.
Results of tests of the M200 concrete for attrition modified and unmodified KM SILOR-ULTRA composition Tests showed that attrition of the modified samples of concrete decreases by 5 times in comparison with unmodified samples, that can be explained by reduction of porosity of a cover and as a result increase of durability .

So we should carry out a series of energy saving and emissions reduction work immediately, to create a conservation-minded society.
In the initial stage of architectural design, through use Weather Tool to analysis, we can know the meteorological data of the local building site intuitively, it can provides a favorable basis for the design of green building, and reduce the building energy consumption more effectively [3].
Only in this way, can we creating a conservation-oriented society, accomplish the slogan of "energy conservation and emission reduction, low carbon life".

Simulation results show that the scheme can effectively retain the signal singularity based on information to achieve obvious noise reduction Introduction According to the coal mine enterprise's production characteristics, two sets of main fan in air shaft is the oversize load key equipment of mine production.
Mine TUNNEL noise analysis According to the analysis of mine tunnels electromagnetic radiation disturbance data [1], transmission line in tunnels is symmetrical three-phase, and it basically does not produce electromagnetic radiation interference.
DENoise principle Usually the main filtering method we use is the smooth communication signal Fourier transform, the signal in the time domain features are mapped to the frequency domain analysis, and through the band filter to achieve noise reduction [2].

The complex-impedance analysis results showed that the reduction in dielectric loss of CCST-M-1 sample can be attributed to the increase of grain boundary resistance.
The real circles are the experimental data and the line is the Arrhenius fitting.
Fig.3 Temperature dependence of the dielectric constant for dielectric relaxation in CCST-M-1 ceramics, the real circles are the experimental data and the line is the linear fitting.

It may be suggested that the reduction in dielectric loss of CCST-M system can be attributed to the grain boundary effect.

With requirements to air quality for human’s living, energy conservation and emission reduction, motorcycle emission in our country is in strict accordance with Euro III standard, while use of EFI (Electronic Fuel Injection) control system is one of the main measures to achieve the emission requirements.
It not only fulfills the requirement of energy conservation and emission reduction, but also improves the performance of control system.
Related data shows that if the air-fuel ratio is kept around 14.7, performance of gasoline engine is optimized [1, 2].

Bending tests in either 4-point or ring-on-ring loading provided the fracture stress data, which were further analyzed in terms of Weibull statistics [10].
To predict the failure stress in larger components the data are extrapolated from small specimen results.
Since especially the high temperature measurements were based only on a limited number of data, the average MOR of the anodes was calculated assuming that all measurements generate a single m-value due to the same flaw distribution.
Based on normalisation of the data using the MOR values for the oxidised, reduced, RT and HT state, an averaging characteristic Weibull modulus of 13.2 ± 1.2 was obtained.
The reduction in fracture stress can be calculated [15].

Peak reduction problem.
The algorithm is sufficiently scalable and can be trained on historical data as well as online in a dynamic environment.
If trained well and on data with a high variation, DQN can sometimes outperform human performances on complex tasks.
One can try to initialize the weight of the Q-Network by applying a supervised learning phase with historical data gathered from existing optimization algorithms.
The main controller is a PLC, which controls the production machine, communicates with partners and obtains energy data from the drive and the power supply via Profinet.

Based on the observation of drilling cuttings data and analysis of geo-chemical testing of a lot of samples in the eastern part of the basin, the content, type and maturity of Jurassic hydrocarbon source rocks were studied, furthermore, the distribution and potential of source rock were discussed throughout the basin The research is significant to the gas exploration.
For the lower Jurassic, the sedimentary and geo-chemical environment (from oxidation to reduction) was unfavorable for the preservation of the organic matter, and another, the lower Jurassic strata was absent in large areas in the basin; Middle Jurassic was favorable for hydrocarbon generation for big thickness, high dark mudstone content etc. in addition, the depositional environment from weak reduction to reduction was suitable for the organic accumulation.
Mid-Jurassic dark mudstone distribution Based on the above analysis, the middle Jurassic sourc rock was most important in the basin, the dark mudstone distribution of middle Jurassic source rock was mapped through the combination of partial and whole data.
