Geomagic can build perfect polygon model and mesh from point cloud data easily and also can convert them into NURBS surface.
In fact, it is necessary to adopt different reconstruction method according to the type of data and the purpose of implication.
The reconstruction scheme is geared to the data source of CT/MRT, and the technical route of reconstruction model is shown in Fig. 1.Obtained the image data after CT/MRI scanning are stored and processed as DICOM format, and then put the data into Mimics.
The other is that the point cloud data is loaded in Imageware software in which characteristic curves and surfaces are gained.
Firstly, the original point cloud data of molar and incisor is gained and optimized in ATOS optic system.

Energy saving and emission reduction.
Although the building energy consumption statistics using advanced scientific methods, to ensure the authenticity of data, representative, practicality, but if the national spot, will greatly increase the workload and the difficulty of the investigation.
Building energy research content, the lack of a single data, is one of the fundamental problems in an industrial building energy need to solve.
On energy saving of industrial buildings, consume inventory Chinese energy more focused research on total energy consumption, but only on the basis of survey data can not reflect the sales terminal building energy consumption energy consumption, and can not reflect the relationship between city environment pollution index, building energy consumption and building environment, also cannot reflect the building energy consumption and its influence factors (energy, energy structure climate change, energy efficiency), the relationship between.

This depends on the characteristics of the particular load data.
The basic idea is to compress the load data acquired in the first time domain (sampling rate) into equivalent load data for the second time domain (load step).
Then, additional interfaces for data exchange are needed.
In the control the load data are captured.
The purpose of the module Load data compression is primarily the generation of equivalent load data for a load step of the thermal model.

The nitrides precipitated upon nitriding in the bulk were found to be unstable during H2 reduction at 470°C.
To this end the XRD-patterns recorded from the surface of the nitrided specimens were analyzed employing the software X´Pert HighScore and utilizing the data-base of the International Center for Diffraction Data (ICCD) [8].
§ The nitrides in the bulk are unstable with respect to hydrogen reduction at 470°C, which results in their dissolution leaving W-rich regions (“W-clusters”) at the locations of the original nitride precipitates, due to the very low diffusivity of W in ferrite at 470°C.

The real success and impact of a strain scanning experiment depends on the quality of the collected data and its practical use.
The bulk of the data analysis is generally undertaken after the experiment and off-site.
In the same line follows that only the most basic data analysis software can be offered by the facilities.
This can lead to a significant reduction of time spent on sample mounting/changing during beam time.
This concerns the control of experiments (operation) as well as the post-processing and evaluation of data.

Photonic services represent a new type of multi-domain, end-to-end network services, besides traditional data transmission enables also real-time and non-data transmission over photonic networks.
Such capacities are achieved by simultaneous data transmission of hundreds of wavelength channels and continuous increase in channel transmission rate.
The majority of present data transmission is packet oriented.
All network application benefits from the low transport delay, ranging from interactive (e.g. video conferences, of interaction between a user and a “cloud”) to traditional data transfers.
High Definition Video and Cave-to-cave This group of applications has mildest requirements on network and can tolerate latencies of a few hundreds of millisecond and latency jitter in tens of millisecond due to buffering and data loss concealment.

Structure parameters of tetragonal Bi(Mg1/2Ti1/2)O3 were refined from laboratory X-ray powder diffraction data (a = 4.033(10) Å, and c = 3.938(10) Å).
Since the high-pressure synthesis is done under extremely reduction atmosphere, these materials have been prepared with the assistance of the strong oxidant.
X-ray diffraction data were collected at RT on a MAC Science Co., M03XHF diffractometer using Cu Kα radiation in the region of 2θ between 5 and 120º with an angle step 0.04º.
The present data were successfully refined to the R3c structure with similar parameters to those for BiFeO3.

Using input data of end mill geometry, wheels geometry, wheel setting and machine setting, the NC code for machining will be generated directly from a solid modeling then used as input to simulate the end mill machining in 3 Dimension before machining.
If using traditional design method to determine the structure and parameters of an end mill, the designers need access to large amounts of data and rules.
Using the input data for end mill geometry, wheel geometry and machine setting, the computer program will generate the grinding points for helical-flute, relief angle, end teeth angle and gashing.
The prediction of the end mill geometry for the determination of the proper configuration before generating the NC code for machining in a CNC machine is necessary for time-saving and reduction of the manufacturing cost.

The calibration was carried out by introducing in the numerical model data on the shift of the TTT curves due to applied stress and the transformation plasticity coefficients, which were obtained through an extensive dilatometric analysis.
The model was calibrated by implementing accurate material data, with particular regard to phase transformation kinetics as a function of the applied stress.
The poor thermal contact between the vertical wall of the component and the tooling caused a significant reduction in cooling rate, which accelerated the formation of a softer microstructure.
Data about the phase transformation kinetics were obtained through an experimental campaign carried out on a testing apparatus that can replicate the thermo-mechanical cycles of the process and record the phase transformation onset by means of an axial extensometer adapted to work as a dilatometer.
