This paper proposes a reduction in the deficit of electricity in the energy system in Tajikistan, by optimizing the operating conditions of hydroelectric power plants of the power system.
However, after the launch of the next unit and the corresponding reduction of the load of each of the operating units, the incremental rate in each of them, therefore, in the entire station is significantly reduced.
Incremental rate obtained for Nurek, Baipazinskaya, Sangtuda-1, Sangtuda-2, Golovnaya and Kayrakum hydroelectric power plants are the main source data using the method of Lagrange for optimization of the energy system of Tajikistan.

The percentage reduction in LL between the natural soil and 25% SS treated soil is nearly 50%.
The result also showed a 41% reduction in PL between natural soil and 25% stabilized soil.
This increase in particle size corresponds to a reduction in surface area.
This represents an increase of 28% in MDD and a reduction of 11% in the OMC value of the soil.

Study of the Paper Consumption Pattern Based on the Low-Carbon Development of Cities in China LI ZhiJian1, a, HAN Qing2, b 1College of Pulp&Paper Making, Shaanxi University of Science&Technology, Xi’an, China 2College of Resource&Environment, Shaanxi University of Science&Technology, Xi’an, China alizj@sust.edu.cn, bhanqing2@sust.edu.cn Keywords: low-carbon cities; paper consumption; carbon dioxide; energy conservation and emission reduction.
According to the data in Table 1, in the past 10 years, with the improvement of economy and people’s living standard, China’s paper consumption has increased rapidly by double digits annually.
According to the data in Table 2, China's energy consumption per ton of paper and paperboard has dropped to 0.45 tons of standard coal in 2007 from 0.60 in 2000 due to the technology improvement (the top priority in reducing energy consumption in the past), and has reached world advanced level (0.5 tons of standard coal), which means there is little space for unit consumption to continue to decline.
If consumers could know more about that, and choose the relatively low-carbon paper, then they will also make some contribution to the reduction of carbon dioxide emissions.

Data acquisition Data acquisition is divided into contact acquisition and non-contact acquisition.
In fact, not all of the data points to play the role of model reconstruction, according to the number of measuring points and the regularity of the point cloud data, and can be divided into the scattered data points and rules of data points. 
After the data acquisition, the collected data must to be processed. 
This process includes waste point deletion, format conversion, point cloud data multi-view point cloud registration, point cloud filtering, data reduction and point cloud block etc.
Using the point cloud data modeling process, due to the massive data point exists, the storage and processing of the point cloud data has become a bottleneck can not be a breakthrough.

Vibration and acoustic data were collected simultaneously during braking to identify the braking condition.
The data analysis focuses on the low frequency domain.
The determination of the source will aid in brake noise reduction efforts and reinforce the vibration analysis method as a system identification method for brake noise.
THE DATA IS ANALYZED IN THE FORM OF SOUND SPECTRUM AND VIBRATION SPECTRUM.

This calculation was compared to the measured data and, statistically speaking, the maximum deviation was of 10%.
Chart showing lineally decreasing savings according to the outdoor temperature For evaluation of the yearly savings were used climatic data, from which was chosen 50-year average within an average heating season.
Each heating season is in the climatic data defined by number of months of heating, number of days in the heating month and average outside temperatures for the individual months of the heating season.
Chart of savings appreciation rate From this data we can read that the savings achieved for the monitored room reached 38 % during the heating season in comparison with the continuous heating mode.

Traffic simulation technology is used to simulate traffic situation, and provide data base for selection and comparison of different proposals, whose most important problem to be solved is that simulation data can match with the actual situation.
To ensure the realistic of the simulation data, we use the method which is the organic combination between GA and SPSA to calibrate the simulation model.
Traffic micro-simulation technology can provide a experimental platform of the organic combination between road and traffic to get the traffic flow data which provide data base for working out the traffic management and control program[1].
By testing the effect of parameters on traffic flow data outputted (velocity, volume) from the model, we can obtain the data shown in Fig. 1, Fig. 2.
Compared calibrated before and after outputted data of traffic flow with real traffic flow data, the paper verifies the efficiency of application of traffic simulation technology in traffic management.

According to the results of [21], some carbon residue is inevitably present in the products of carbon-thermal reduction.
The disadvantage is the lack of data on the reduction of complex oxide compounds, which may be part of man-made raw materials.
This can lead to probable differences in the course of the reduction reactions.
However, in [20] the reduction is accompanied by the formation of carbides Cr3C2, Cr23C6, Cr7C3.
This is in good agreement with the results of works on the reduction mechanism of W [18, 19] and Mo [17] oxides.

The experimental data was firstly processed utilizing the method of multi-factorial total probability formula evaluation.
Connecting with the practice of production site, the weights of IS, RS, HS, SS and TS were select to be 0.1, 0.2, 0.3, 0.1 and 0.3 respectively. 2.2 Experimental analysis Statistics and regression analysis in Minitab 16 were used to process data.
So the cost reduction of the new formula is obvious in general.
Organic matter easily decomposes at high temperature, so C1 and C2 are significant to the high temperature performance, which is also shown by the data of Table 3.
Low-cost carbon-based briquettes for the reduction of NO emissions: Optimal preparation procedure and influence in operating conditions[J].

The task of cost reduction may be solved through application of the less expensive materials in comparison with carbon fibres.
An application of hybrid reinforcing fibers and of strengthened matrix will permit a considerable reduction of the blade cost without significant loss of physical-mechanical properties of the material.
Data in Table 1 are the proof of the mentioned advantages of autoclave method of hybrid composites.
Figure 4 Increasing of strength and elasticity characteristics of composites as a result of reinforcement of matrix with mullite-similar addition - series C; - series D According to data given in Fig. 3, substitution of carbon reinforcing structures for basalt ones leads to the maximal drop of strength and elasticity modulus on tension accordingly by 46% and 32%.
The substitution of 20%-40% high-strength and high-modulus carbon fiber for high-strength basalt in hybrid polymer composite provides an acceptable reduction of strength and stiffness in tension and compression allowing its use in wind power turbine blade applications. 2.
