Aiming at the shortage of investigations above, the text makes use of the laser equipment to measure the parts rough surfaces and gets sub-nm level rough surface topography data, then utilizes wavelet to make multi-scale analysis and reconstruction after noise reduction.
The contact model is built based on rough surface topography data in ANSYS.
Based on the problems above, the text firstly uses wavelet[8,9], which has the advantages of multi resolution and multi dimension analysis on time-frequent in signal disposal, to denoise the data, then to decompose the data in different frequency and reconstruct suitable low-frequency components which are inputted to ANSYS to build the microcosmic contact model.
The laser measure equipment which used in thesis to measure the rough surface has a high sampling rate and accuracy in measurement offers original data for micro contact study.
The contact model based on different scale could be set up by taking advantage of the wavelet to pick-up different level roughness in measurement data.

This paper proposed the snow disaster risk assessment model in pastoral areas based on the data of environment & disaster monitoring and predicting small satellite.
After the massive experiment monitors and the contrast confirmation with the disaster situation data in National Disaster Reduction Center, the model forecasting result and the disaster situation statistical data have good uniformity from the space position and the risk degree.
The automatic extraction result of the snow coverage area is modified artificially combining the experience and knowledge of experts and other supplementary data.
The data of environment & disaster monitoring and predicting small satellite and Moderate Resolution Imaging Spectroradiometer (MODIS) data have a lot of similarities considering revisit period and band setting, etc, in addition to resolution, so the use of the data of environment & disaster monitoring and predicting small satellite for snow depth inversion can be based on the inversion method of MODIS data.
The process of snow disaster risk assessment validation The results of this study indicate that the assessment outcome from January to February coincides well with the statistical data in terms of space location and risk level.

Consequently, the above reviews induce the objective of this work to determine the feasibility of using low-grade ethanol of acid value reduction process in mixed crude palm oil (MCPO).
Fig. 1 is the schematic diagram of acid value reduction process using the stirred tank reactor and 6-blade disk turbine (rushton turbine) to mix the oil and chemical reactants.
Response surface model (RSM) was analyzed from data in Table 4 using a multiple regression model to fit a second-order polynomial equation.

The results showed reduction in density, compressive strength and consistency and an increase in setting time, and flexural strength.
Mostly, the data in this regard pertains to the hardened state of the material.
Both Needle test and flow table test authenticate the reduction in consistency. 2.
Reduction in consistency indicates that the particles absorb water and thus enhance water requirements. 3.
Reduction in density is attributed to lower density of the particle. 4.

The work introduces a demonstrational example of measured, processed and evaluated data of an experiment where parameters of vibrations, which were created due to water jet technological head parameters changes, were scanned.
The data are scanned with an accelerometer representing part B in the scheme.
Communication with the computer is performed by an interface USB 2.0 with speed up to 100 kS/s/channel and 400 kS/s/module with total data flow up to 5 MS/s.
Making of tasks within object-oriented programming environment of LabVIEW with further widening and further data processing in a case of a portable computer using means that the system is completely portable [1-4].
A) Data recordings of a planned experiment B) A digital record of an analog output of the accelerometer of material cutting C) Relation of vibration parameters to an analyzed technological and material parameter.

Data is collected from the literature considering the GT GE LM2500+G4 operating under similar conditions [5], OTSG for the comparable application and parameters [7] and ST with similar use and power output capacity [28, 29].
Combined Cycle Emissions Reduction: CCS.
The reduction of the number of theoretical plates in the absorber and, consequently, its height, is then assessed.
The height reduction is then limited to the maximum amine flow-rate (625 t/h), as shown in Figure 3.
Simple Cycle Emissions Reduction: CCS.

Fig.4 Variation of sedimentaion amount of Fig.5 Variation of void ratio of the soil solutions with time with applied load 3.2 Experimental data analysis Specimen 1 had the following parameters: the wet weight of the back-silting soil m=96.8g, dry weight ms=57.713g, water weight mw=39.1g, volume of the cutting ring V=60cm3, initial density of the back-silting soil ρ0=1.61g/ cm3, water content of the back-silting soil w0=40.4%, the height of the specimen before tests h0=2.0cm, related density of the soil particle ds=2.75, initial void ratio e0= =1.39, net weight of the soil frame hs=h0/(1+e0)= 0.84cm.
The magnitude of reduction was large at the initial stage (close to linear reduction), and decreased gradually and then remained stable at a certain value
(3) For Specimens 1, 2 and 3, when loaded from 12.5 kPa to 100 kPa, the reduction of void ratio was respectively 0.148, 0.187 and 0.207 (an average value of 0.18) with a percentage of reduction of respectively 17%, 24% and 23%, suggesting that the compressibility of sedimentated back-silting soil was good and should be highly regarded.
The magnitude of reduction was large at the initial stage (close to linear reduction), and decreased gradually and then remained stable at a certain value
The reduction of the three sedimentated back-silting soil reached an average of 21%, suggesting that the compressibility of sedimentated back-silting soil was good and should be highly regarded.

That’s is to say, 70% of the core emission-reduction technologies are need to be imported.
In China, the making and implement of policies for low-carbon industry development and saving energy as well as emission reduction are mainly led by government with administrative means to limit the local government and enterprises by progressive realization of energy-saving and emission-reduction indexes.
Then using the low-carbon concept to transform and improve traditional industry for energy-saving and emission-reduction.
On one hand, the government should lead the commercial bank to put the energy-saving and emission-reduction index, resource recycling, pollution emissions into the system of loans, investment and risk assessment when they issue commercial loans.
Capability constructing includes many respects, such as technical standard, technical information, technical data, equipment instrument, calculation software, technical consultation, product certification and technical training, etc.

The required input data were rolling speed, furnace temperature, initial and final thickness of the specimen, roll radius, roll contact time, corresponding temperatures, frictional rolling reduction and specimen width.

There is a lack in literature data about welding of these steels, particularly regarding to laser beam welding [6].
The increased hardness of the welded regions elevated the levels of tensile strength, but reduced the ductility; this reduction was associated with increasing the hardness of the welded region and the formation of small defects.
In both types of steel used there was a reduction in fatigue performance.
The welded steel 300M has reduction fatigue life more pronounced than the steel 4340 due to the difference in chemical composition.
The fatigue limit of the 300M steel was reduced to around 50% after welding while for 4340 steel the reduction was around 15%.
