And this data structure is usually implemented with a layered C++ class.
SAT file format can exchange data with most existing 3D software data formats, including CATIAV4, CATIAV5, IDEAS, IGES, etc.
The exchange with other data formats is implemented mainly through InterOp, because the conversions of most common data formats are integrated in InterOp
Point cloud of Model 4.1.1 Data measurement and processing The point cloud data of the transected surface obtained by Arm Coordinate Measuring System is shown in figure 2.
Point cloud measured by CMM Then, the measured data is analyzed, and reverse engineering analysis should rely on a data model and all data results are mutually compared for choosing the optimal industrial design plan.

An effective way to solve this problem is the effective evaluation and the cost reduction by the evaluation.
The data from a smart building micro grid is used to validate the method.
Fig.2 DG output and load curves in the typical day In order to analyze the effect of energy storage system cost reduction and the micro grid evaluation index, the micro grid operation cost calculation is carried out in different storage penalty factor and energy storage scheduling . 1) Energy storage system in sheduling mode without panaty factors When the micro grid work in in energy storage sheduling mode, the TOU tarriff is considered, and the micro grid buy power in valley period, while sell in peak period for lower cost.
So the cost reduction is of great importance for the micro grid developmemt.

The damage progression was also evaluated using stiffness reduction and hysteresis loop analysis in order to obtain dynamic and secant modulus.
The data acquisition frequency was set to 1 Hz to avoid noise and loss of signal.
After 120000 cycles, the stiffness reductions in both dynamic and secant modulus were about 4-5% at a load level of 70% of ultimate load.
Despite limited data points, the S-N curves generated in this work show that the stress limit is around 80% of the normalized ultimate tensile stress level.

It was found that, at the early stages of the scale reduction, the relevant reaction occurs at the oxide/metal interface between chromia and carbon from the alloy.
Then we characterize the system involved in the scale reduction and we develop a model based on the thermodynamic of the reaction.
This observation is in agreement with the proposition made by Quadakkers [2] who stated that TA is the equilibrium temperature of the chromia reduction by carbon (Eq. (1)).
(T) is extrapolated in the range 850-1000°C from data published in ref. [19] for higher temperatures.
Log(P(CO))=f(1/TA) for Haynes 230® and model alloys - experimental data and theory Conclusion A model is developed to rationalize the variation of the critical temperature for surface oxide removal TA as a function of the CO partial pressure in the gas phase.

The inserts profile and geometry data are presented in Fig. 1.
Significant amount of reduction of chatter amplitude may be observed from this figure.
Reduction at other conditions is not that significant.
Reduction of the amplitude of machining vibration at other trial runs is shown in Fig. 4.
Heating at 420 0C helps in lowering down acceleration amplitude and the maximum reductions were 600%. 3.

Thus, the reduction of the primary particle size and application of amorphous precursors could enhance the densification of Si3N4-based compacts.
A new possibility for preparation of Si3N4 based powders comes from the top-to-bottom method, if particle size reduction could be achieved by the fracturing and wear of tough silicon nitride particles.
The reduction of AlN crystallite size was noticeable after milling for 30 min. with silicon nitride balls.
Thus, it could be concluded that in the first step the reduction of the size of AlN crystallites took place and was followed by the oxidation of the fine particles during prolonged milling.
Measured and calculated from the XRD data weight fraction of oxygen in the activated powders The measured oxygen content was always higher than that calculated from the XRD results, thus oxidation of silicon nitride during milling is confirmed.

With M=46 (Hamming) the two window have equal main lobe width but the proposed window offers -5.3 dB side lobe reduction.
The reduction in side lobe peak is 18.5 dB with M=10 (-55.2 dB compared to -36.7 dB).
It is obvious that the proposed window also outperforms the Hanning and Bartlett windows because Hamming window shows better side lobe reduction than these windows for the same main lobe width.
Finally, for the same specification proposed modified Lanczos window shows more side lobe reduction with slight increased main lobe width in comparison with *new window [9].

Artificial rainwater was prepared from the chemical properties data (the averages) of rainwater in Thailand shown in Table 1.
Average volumes of leachants were calculated from the data of rainfall obtained from the past 10 years in the central region of Thailand.
The volumes of leachant (the artificial rainwater) were calculated from the data of average rain volumes per month in the past 10 years in the central area of Thailand.

This may turn into Sf lowQoS, such as low response to web queries, unsatisfactory VoIP communications and limited streaming of data.
Indeed, moving from the (On/Off, FIFO) strategy to the (On/Idle, FIFO) the response time T changes from 84 sec to 1.8 sec (an almost 97% reduction), while moving from the (On/Off FIFO) strategy to the (On/Idle, SPTF) the response time T changes from 84 sec to 16.5 sec (an almost 80% reduction)

Mt+2 and Mt +4 are deactivated by oxidation-reduction during monomer polymerization.
In the following simulation experiments the trends of the MW and MWD change have been anticipated by the usage of data taken from the real experiments.
Using the computer simulation, the prediction of the trends of the MW and MWD change in time has been made for the real experimentally proved data [9] of polypropylene polymerization by the catalytic system MgCl2/ethylbenzoate/TiCl4/Al (C2H5)3.
