Reducing the static cutting edges via segmenting the wheel which automatically leads to reduction of momentarily engaging cutting edges results in a reduction of rubbing and plowing regimes and therefore a decrease in the specific grinding energy.
Reducing the static cutting edges via segmenting the grinding wheel which automatically leads to reduction of momentarily engaging cutting edges results in a reduction of rubbing and plowing regimes and therefore a decrease in specific grinding energy.
In order to achieve reliable data each test was repeated three times.
Hence grinding forces acting on each active grain are decreased, resulting in a reduction of total grinding forces.
Furthermore, the considerable force reduction by employing the T-Tool wheel may also be interpreted as a reduction in the generated heat in the contact zone.

Data sources and processing The primary datasets used in this study was three landuse maps of 1981, 1990, and 2000 of the study area.
These data were digitized from paper topography maps with a scale of 1:5000.
The major data processing steps included: (1) creating TIF raster data files by scanning the topographic maps in MapGIS, (2) geometrically correcting the scanned data and registering them for on-screen digitizing to generate the vector data files, (3) using the codes of parcels to link the spatial data with their attributes, (4) transforming MapGIS vector data into ArcGIS vector data formats, and (5) converting vector data into raster data and aggregating original landuse types into five classes: agricultural land, urban land, forest meadow, wetland and water bodies.
As a result, the area of agricultural land decreased with a net reduction of 122.76 km2 during the decade.
The net reduction of water bodies was 17.17 km2.

The main work of memory cutting is aimed at the data which first time cuts in advance to the driver carries on processing, uses for to control cuts arm's movement, realizes memory cutting and the display and the warning process.
The real-time communication connection mainly completes with the lower computer communication duty, it is the communication connection which superior computer issuing orders and receives the data.
Simultaneously the numerical display window is configured, which used to display the data for real-time location of the cantilever movement pointer value.

For these points, reusing knowledge from historical data becomes a natural option.
Based on company's sales records and product documentations, the links between customer needs and purchased products related to which product satisfies which customer can be identified and they are represented as {( * * ,s tr v )|∀s∈[1,S],t∈[1,T]}, which acts as the original data of knowledge discovery to product family planning in this research
Algorithm for Attribute Reduction.

Based on the presented data, a possible growth model is proposed to clarify AIC mechanism.
The reduction of agglomerations on the a-Si surface is due to the diffusion of Al agglomerates into silicon.
From the XRD data, XRD signals at Si(111), (200), (311), Al (111) and Al (200) were detected which indicates the formation of nanocrystalline material.
Inspection of the data of Fig. 2 reveals that the AIC process has produced crystalline fraction at temperature above 500oC, with a peak centered at around 514 cm-1.
There is a clear tendency of reduction of resistivity as the annealing temperature increases.

The approximate merging of two adjacent B-spline surfaces into a B-spline surface is the core problem in data communication.
Introduction Data conversion is a core problem in data communication between different CAD systems [1-4].
In [1], hoschek proposes that approximate conversion include two problems: degree reduction and merging.

In the second heat treatment alloy the work hardening data showed a single linear region at high stresses, whilst no linear stage occurred at low stresses.
In HT2 material the work hardening data show a single linear behaviour, limited only at high stresses.
The linear data at high stresses are not significantly different to the HT1 alloy and they can be attributed to the Stage III of work hardening, i.e.
In the HT1material the work hardening data presented two linear regions: at high stresses the linearity has been described as the conventional Stage III of work hardening, whilst at low stresses the data linearity has not been rationalised in any conventional stage of work hardening.
In the HT2 alloy the work hardening data showed a single linear region at high stresses, i.e.

The impedance data can be collected over a broad frequency range.
This part of the electrochemical impedance data interpretation was critical since several equivalent electrical circuits can be used [12-14].
