Results from the creep tests are summarized in Table 2, which shows the values of stress (s), primary creep time (tp), secondary creep rate (ε·s), final creep time (tf), final strain (ef) and reduction of area (RA).
Creep data of Argon, Nitrogen and Air atmosphere at 600ºC and 250 MPa.
Occurs a decreasing of steady state creep in function of the reduction of oxidation process, showing that for the Ti-6Al-4V alloy their lifetime is strongly affected by the atmosphere that is submitted because the oxidation suffered by the material.

This leads to a reduction of the tool lifetime or to tool deformation.
This study deals with the investigation of possibilities for the reduction of tool wear.

The application of lubricants causes an additional reduction of the process forces.

Safety Statistical Analysis based on Urban Rail Transit Operation Yanhui Wang1,2,a,Jun Jin1,2,b,Lingxi Zhu1,2,c, Yong Qin1,d,Ping Li3,e 1 China School of Traffic&Transportation，Beijing Jiaotong University，Beijing 100044，China 2State Key Laboratory of Rail Traffic Control&Safety，Beijing Jiaotong University，Beijing 100044，China 3Beijing Rail Traffic Control Center，Beijing 100044，China ajinjun12121012@163.com, bzhxywyh@126.com, czhulingxi@139.com, dqinyong2146@126.com, elping@bii.com.cn Keywords: Urban Rail Transit Operational Safety Indicators Information Statistical Analysis Abstract: Aiming at the characteristics of the safety of urban rail transit system operation, this paper adopts the comprehensive analysis and statistical chart included by the statistical analysis to process the data, which is based on the relevant data in accordance with Beijing Rail Traffic Control Center Statistics in 2012 and indicators of the station, line and road network, in addition, the trend and
Finally, the laws can be find out, and the specific prevention measures can be put forward for the management, which has a certain significance for the reduction of accidents, and can give some theoretical guidance to urban rail transit operations managers.
Statistical analysis based on of urban rail transit characteristics This paper uses the statistical analysis to its quantitative research according to the data of Beijing rail traffic control center in 2012.
Fig.7 The average monthly passenger of urban rail transit road in 2012 Figure 7 shows that the highest passenger traffic in July and August, and the lowest in January, which is mainly the different holidays in different months, and July and August are a time when holidays or open semester, and May Day is the highest through the statistical data, following Qing Ming Festival, and while Spring Festival minimum.
It can play a very important role in guiding through the statistical data, roundly and timely mastering the system operators and the key factors which can grasp the indicator trend and the law, recognizing potentially risks, and take the effective precautionary measures to ensure the safety of passengers, smooth travel, and reduce accidents.

The reflectance data were transformed into the Kubelka-Munk values.
Potentiometry The potentiometric titration data obtained in each case is depicted in Fig.1.
X-ray Photoelectron and FT-IR Spectroscopy The C 1s, Ti 2p and O 1s data of TiO2 and CMT is presented in Table 1.
They are based on the XPS and IR data presented earlier.
This hypothesis is supported by XPS and FT-IR data discussed earlier in this study for surface carbonate.

The data of the base year is the basis for the planning.
Generally speaking, the planning often chooses the closest year with relatively complete data and information.
The task of the control and planning of the total amount of marine pollutant is specifically embodied as below: The government needs to have a comprehensive grasp of the basic data of the nature, society and economic development of the targeted sea area and the region.
In the process of collecting and sorting the data, systematic and comprehensive investigation, analysis and evaluation need to be made on the status quo of the environmental quality and the source of pollution of this area.
The country thoroughly implement the scientific outlook on development, adhere to the principle of combining the control of increment and reduction, strengthen pollution reduction and control work by readjusting industrial structure and optimizing industrial layout.

To extract feature from the acceleration data, they convert three dimensional data into one dimensional vector using vector quantization [5].
Fig. 3 shows the example of raw data.
Fig.2 Data collection apparatus a) b) c) Fig.3 Accelerometer signals for different handwritten characters a-the data ‘0’, b-the data ‘3’, c-the data ‘9’ Feature Extraction Feature extraction is the elementary problem in the area of pattern recognition.
Therefore, we proposed a effective features fusion method from acceleration data in this paper.
PCA is one of the well-known dimension reduction methods.

The construction market has at its disposal more and more technical solutions in sealing materials that allow cost reduction and short term execution for construction companies.
Introduction Water-proofed gypsum blocks constitute a construction system that promotes the reduction of load, cost and waste of building materials [1], being therefore an attractive option from an ecological point of view, also because of a low energy demand during the production process [2].
Based on the cited data, it can be concluded that the addition of stearic acid to the gypsum did not afford the formation of water-repellent gypsum according to absorption standard ABNT PN 02:013 – 40 – 009 (5.00 %).
The micrographs shown in Fig. 6 allowed an understanding of the data cited above.
The obtained data can be adjusted by linear regression, revealing accordance with prior studies carried out with ceramic and stone materials [1,3].

The improvement in the heat exchanger's Tout and the reduction in (Tout) exhaust illustrated the positive impact of installing this device.
Measured temperature, velocity, and effectiveness data for Case I (30-minute duration, initial exhaust gas temp 61°C).
Measured temperature, velocity, and effectiveness data for Case II (60-minute duration, initial exhaust gas temp 77°C).
Measured temperature, velocity, and effectiveness data for Case III (90-minute duration, initial exhaust gas temp 84°C).
This was reflected in the higher outlet temperatures and the reduction in exhaust temperatures, indicating effective heat transfer.
