Data analysis.

Data Preparation The data used in this study includes ecosystem carbon storage (density) data, ecosystem carbon sink data, and carbon sink potential and carbon emission of land use data of Shenzhen.
-II survey data on forest resources and the measured soil data of Shenzhen City.
Ecosystem carbon sink data is simulated by the IBIS model, the data for IBIS includes meteorological data, vegetation data and soil data etc. the routine meteorological data is sourced from China Meteorological Data Sharing Service System (http://cdc.cma.gov.cn/).
Part of soil data is come from the national interpolation data of the fourth National Soil Survey with spatial resolution of 5 x 5 km.
Soil carbon content data is from the measured soil data of Shenzhen [4].

With the accumulation of air quality data, viability and importance of data analysis and application gradually emerges.
Correlations between the factors are found by exploring data, and the effects of correlations on weight determination are considered.
I have issued a simple preprocess procedure that eliminates most correlation in the data set and therefore improves the evaluation results of standard deviation method.

Baum-Snow and Kahn (2005) have shown considerable reduction of the mean time of trips in the areas which are adjacent to urban rail transit compared with the far away areas and this is because of rail transit’s high speed compared with bus or private vehicles under the same conditions [4].
Fig. 1: Plan view of Ahvaz urban subway lines [1] Data Based on detailed study of Ahvaz traffic and systems, the number of population and travellers in different time periods are mentioned in table 1 according to required number of urban rail lines.
Reduction of energy consumption Considering 0.13 lit. of gasoline consumption for each kilometer and also 2.5 passenger For Gasoline fuel injection vehicles, fuel consumption for each kilometer and for each person will be 0.025 lit.
Based on the obtained data from Environment Org. the amounts of distributed pollutions caused by burning one liter of Gasoline engines are mentioned in Table. 2.

According to its safety data sheet, this agent is based on 5-ethyl-1,3-dioxane-5-methanol, 2ethylpropane-1,3-diol and propylidynetrimethanol.
The above described measurement device is equipped with one movable head which is leaning against the inductive sensor connected to the data logger, which stores the data with the frequency of 5 Hz.
The estimated reduction shrinkage due to addition of SRA is about 1500 µm/m.
Based on the results, it can be stated that the highest benefit of the SRA addition was found in reduction of the risk of AAS composite cracking.
The ways of the shrinkage reduction in AAS composites have to be further intensively investigated.

Fig. 2 Schematics of electropolishing process Data and Discussion Determination of Current Density and Voltage Fig. 3 Current Density – Voltage Curve Based on the Figure 3, it can be observed that at a voltage of 6.1 Volts, there is an electropolishing region with a constant current of 45.3 Amperes and a current density of 156.15 A/dm².
Fig. 6 Relation time on surface roughness In the case of time variation from the obtained data, it is evident that the longer the polishing time, the higher the reduction in surface roughness.
This is supported by the findings from my own research, where the average reduction value was obtained as 57.246%.
Once the curve is formed, a data fitting process is performed to determine icorr and Ecorr by drawing straight lines on the anodic and cathodic parts of the curve until they intersect.
The data fitting results for the specimen can be seen in Table 3.

It has been reported that appropriate surface modifications (surface dimples) leads to dramatic reduction in friction co-efficient.
For these dimples, friction reduction results were best for Elliptical dimples followed by square and circular dimples [2].
Machine is attached with a data acquisition system and WINDUCOM 2010 software which gives result values and graphs.
In presence of lubricated conditions, a significant reduction in wear parameter of about 60 to 70 percent has been observed.
In case of dry conditions testing, it is observed that maximum reduction in COF was observed for LST discs having dimple area of 0.01 mm2 and maximum reduction in wear parameter was observed for LST discs having dimple area of 0.09 mm2.

., Rostov-on-Don, 344010, Russia aayurvedaom@mail.ru, brudenko-centr@mail.ru Keywords: Sea of Azov, fish, methods, analysis, damage, accident, measures for risk reduction, acceptable risk, risk management.
Problem Statement According to the data of the ecological atlas, in the middle of the 19th century the catch volumes of fish in the Azov Sea reached about 400 thousand tons per year, with the absolute majority being valuable species.
In the conditions of a constant reduction in catches of fish and other seafood, in conditions when the fish stocks of inland water bodies are in critical condition, aquaculture is the only reliable source of increasing the volume of food fish products and serves as a guarantor of Russia's food security.
A significant reduction in the influx of fresh water into the sea is aggravated by the discharge of untreated sewage polluted by toxic substances of artificial origin that are poorly split by microorganisms living in the Sea of Azov.

Comparing with the traditional porous pavement, the LNAP has no only more excellent noise reduction property, but also has the similar drainage performance, so the LNAP has more valuable.
Table 1-5 Resistance to the Salt Corrosion of LNAP Mix Specimen Pull strength before immersing [Mpa] Pull strength after immersing [Mpa] Ratio of pull strength [%] Requirement [%] 1 0.79 0.88 107 >100 2 0.86 0.90 Average 0.83 0.89 Noise Reduction in Lab Research of LNAP Mix In order to verify the noise reduction property of LNAP mix, the acoustics performance tests including damping testing and standing wave test is used to analysis noise reduction property in lab of LNAP mix.
Damping Test To measure the vibration and noise reduction, damping is the capacity unit of dissipating vibration energy, that is to change the mechanical and sonic vibration energy to the heat or other easily dissipation energy and achieve the noise reduction.
The performance data in field of LNAP test trial is acceptable.After one year, the test trial has good performance which it has no damage in the surface and has good surface drainage in the rain day.

- Percent reduction of surface roughness which gives information about surface roughness reduction, using the initial surface roughness [7].
The average surface roughness reduction of the overall trials is 65 %.
Based on quadratic regression between the experimental data and the input parameters, it is possible to determinate the optimum position of the reduction of the surface roughness.
This observation shows a superior value of 50 % improved surface roughness reduction.
