The enormous of data shrew corrosion pattern was usually happened at the edge of topography.
The reduction of the overcoat thickness will degrade their corrosion- and wear-resistance.
Electrochemical Impedance Analysis.The general effectiveness of DLC on corrosion protection was determined by potentiostatic polarization measurements [1,2,4] with data interpretation by the Tafel extrapolation method.
Indirect investigation to verify the DLC films weak point is powerful technique to provide the information for process engineer especially for the new process requirements that always continuously attempt to reduce DLC thickness for achieving better magnetic signal during data storage.
CoNiFe high moment material in data storage device was protect from corrosion with Si3N4/DLC films.

The maximum stress changed from 110.805 MPa to 110.063 MPa with 0.67% reduction.
This result shows that both weight reduction and strength improvement can be achieved with optimum parameters selected.
The real case shows that this method is useful and can be adopted in vehicle body weight reduction.

Lastly, a reduction of the general case is made to prove the general mathematical model on a structure similar to a five axis turning and milling machine.
Parameters q6 and q10 are rotations and are determined using only data from the geometry of the part where q9, q8 and q7, meaning X, Y and Z, are calculated using data from geometry in relation to q6.
This case can be replicated and from the general structure after reduction to have from two axis turning machine to five axis turning and milling machine and from three axis milling machine to five axis milling machine.
Having the geometry of the finished part and the kinematic structure equations, computer software can use this data to aid engineers in real life engineering situations.

For a more active fulfillment of greenhouse gas reduction, diverse environment-friendly reduction activities are being continuously carried out with environment-friendly Building Certification System.
In terms of essential assessment items and methods, Mat 01 item selects the form in which a self-checklist is prepared and corresponding data is attached on the assessment methods used in the project such as scope of assessment, guideline, program, and use of database.
Green Guide is an environment-friendly building material information website developed by BRE of the United Kingdom launched in 1996 to provide environmental impact information of building materials with user convenience based on quantitative data.
Guidelines must include system boundary for assessment, scope of data collection, and details about data collection for analysis of life cycle list, and detailed guidelines are required to have details about assessment items according to characteristics of each material.
Assessment program can assess environmental performance of buildings according to the database for each stage of life cycle using the established environmental performance data of building materials.

Data of scale deformation from Figure 2 verify the deformability of both primary and secondary oxide scales.
Nevertheless, secondary scale proves to be more readily to deformation than primary scale from 900 to 1025 o C under lubrication condition by comparison the two sets of data for primary and secondary scales, showing its potential of plasticity.
The lower the deformation temperature, the smaller scale reduction can be achieved with increasing bulk materials reduction.
The magnitude of scale reduction becomes smaller with a heavier reductions than at a smaller bulk materials reduction when the deformation is carried out below a certain temperature.
It is not difficult to infer from the above experimental data that deformation of oxide scale is more sensitive to rolling temperature and lubrication rather than to magnitude of rolling speeds when rolling is carried out under a given reduction.

And Optical Fiber (OF) with 245μm exhibit about 23.5% reduction.
Rong-mei Liu et al [6] made OF embedded parallel with the direction of the reinforcing fibers (0°), and observed that the tensile strength of CFRPs at [0/-45/45/90/OF/90/45/-45/0]s exhibited a maximum reduction (nearly 7%) as compared to the sample without OF.
Jensen et al [7] have investigated the reduction in compressive properties caused by the incorporation of OF in a graphite/bismaleimide matrix.
In the laminate of [03, 902, 0] s, a strength reduction of 70% and a stiffness reduction of 20% were observed during compressive testing.
And the average of group is gotten from every valid data of specimens.

Therefore, the clustering algorithm for numeric data is not suitable to process the categorical valued data.
Data preprocessing based on data warehouse Data preprocessing is an important work for project estimation.
There are four main steps to do the data preprocessing in application system of cost station. 1) Data cleansing: by filling the vacancy value, smoothing noisy data, identifying outliers, and solving the inconsistent data. 2) Data integration: combine the multiple data sources into a consistent data storage, such as integrating data in different databases into the data warehouse. 3) Data transformation: transfer data to suitable form for mining, such as scaling the attribute data in proportion, and make it fall into a relatively small interval. 4) Data stipulation: on the condition of not influence the mining results, compressing data by data aggregation and deleting the redundancy data, that increased the quality of mining models and reduced the time complexity. 2.1 Data cleaning and integration According to characteristics of various data sources of Xiamen project cost station, our system used xml standard as common export format standard of different data sources.
In process of data logging, user can detect data according to system business and technical rules.
Then, we applied the BP neural network and used MIV method to do dimension reduction.

The laboratory experiments made by author had shown an intensive reduction of specific surface volume at the beginning of grinding, further relatively slow growth and reduction of BET and Langmuir surfaces were observed.
In the ceramic facing-brick and roof-tile industry the reduction of particle sizes is one of the most energy-intensive technological processes not only because of the used equipment and physico-mechanical properties of milled materials, but of the mechanochemical phenomena taking place during fine comminution.
Data collection times were of 2 seconds per steps.
The phases were determined by Search/Match method using powder diffraction data base file PDF2.
After 60 minutes the specific surface reduction diminished considerable and after 120 minutes of comminution there were no remarkable changes in specific surfaces.
