The facile processes were developed for synthesizing vanadium dioxide (VO2) by pyrolyzing ammonium metavanadate (NH4VO3) in nitrogen (N2) flow and by thermal reduction of vanadium pentoxide (V2O5) in ammonia gas.
The VO2 particles were synthesized by thermal reduction of V2O5 in ammonia. 1g V2O5 (99.0%, Chinese Shanghai Chemical Limited Company, Analytical Reagent) was loaded in a ceramic container without cover.
By comparing the results with standard JCPDS card (PDF ID number 43-1051) of XRD data documents, the sample was a match to VO2 pure phase.

Clinical guidelines, Data Mining, Decision Support System, Data warehouse, OLAP Abstract.
The required information in Database or in Data Ware House might be the historical data of patient or the health based summery of different patients in diverse stages.
Xiao et al [1] suggested that distributed decision support systems provides linked anonymised data scheme for patient private data protection.
Another aspect of research work focuses on temporal data Ming in covering large geographical area that produces data for analysis purpose.
The Advance Data Mining Analysis technique is used for extracting only suitable patterns of related information from Data Base.

In this paper, STAF model [18] based on the time series was used to analyze the flow and recycling of titanium resources, and to provide data support and theoretical basis for improving resource utilization efficiency and energy conservation and emission reduction in China titanium industry.
The data are all from the Development Report of Titanium China Industry in 2003-2015.
The materials flow of titanium products in 2005, 2010 and 2015 were calculated respectively based on the statistical data.
All data in titanium flow and circulation means to titanium content provided that without any special notes.
Table 1 Date sources and description date categories sources and description titanium sponge and titanium ingot production import, export and consumption statistical data statistical data titanium content in titanium products assumed recycling rate assumed tailing, slag, scrap, social stock, landfill and waste calculated MFA Indices Resource efficiency indices.

First, disk failure results in temporary unavailability of data or even permanent data damage.
However, excessively high clamping force tended to cause disk distortion in the waviness form along the inner data zone .

Introduce No matter what exhaust after-treatment technology is adopted, a further reduction in the raw emissions of the engine is required.
Structure Optimization of Intake Ports The best procedure is to import CAD-data via the STL-interface and ensure that the CAD-data is showing the same engine as the hardware used at the experimental test rig.

The phenomena of the flow separation on high lift wings is avoidable phenomena where it causes reduction in lift, increase in drag, reduction in plane stability, as well as noise and vibration [1, 2].
In the present study, 2-D wing with NACA4412 airfoil section and an External load (E.L.) which simulates missile model were adopted to obtain qualitative data of the flow structure around the wing and the combination of the wing with attached missile.
The inclination to 5o AOA caused a reduction in the size of the separation region on the lower surface and possibly a virtual elimination of this separation.

A.Tasdemirci, et al, reported that Teflon and aluminum foam interlayer caused a significant delay and reduction in the magnitude of the stress wave transmitted to the composite backing plate and localized damage in the ceramic layer.
Further details of the experimental setup and the standard data reduction routines are available elsewhere.
It cannot be used to generate mechanical property data in the conventional way since essentially all of the necessary assumptions are violated.
We could confirm that the presence of interlayer could alter the stress wave transmission between the layers and cause a reduction in the magnitude of the stress transmitted to the Ti6Al4V backing plate.

The Pseudo-Voigt equation [4] is used to fit the data and to generate result files.
This size reduction accompanies the water loss inducing a lattice change.
To improve the reproducibility and the reliability of the data treatment, a PseudoVoigt fit has been chosen.
For our samples a temperature reduction of about 170°C is observed as the size decreases by three orders of magnitude.
So, this study highlights the applicability of the nanophysical properties to the nickel-bearing compounds and the reduction of the phase transformation temperature.

(a) (b) Fig.2 The curve of the rolling forces vs. increment (a) MethodⅠ; (b) MethodⅡ Transverse Wall Thickness Precision In order to increase the reliability of data of distribution of transverse wall thickness, simulated workpiece should pass through the last stand a longer distance.
Then five slices at exit of the last stand are analyzed, data processing method was introduced in detail in Ref. [8].
Maximal rolling forces, rolling moments all stands except the first stand have some degree reduction using methodⅡcompared with methodⅠ, and maximal rolling force and rolling moment reduce 10%~20% and 10% or so respectively.
Front tension, especially back tension can cause rolling force certain degree reduction.
Diameter increment reduction of rolled hollow tube is not obvious on the condition that front and back tension are small.

Most probably, the observed shift of the position of absorption bands is due to a reduction of oxygen content in the crystalline oxynitride phase formed during annealing from amorphous-like Fig 1.
The gray lines show, in arbitrary vertical scale, the spectra of crystalline phase of silicon nitride or of oxynitride phase in bulk silicon, as derived from the literature data.
The suggested mechanism of the implanted dose effect explains the reduction of the band shift with increased dose of implanted nitrogen.
The corresponding data taken from literature are also included. samples.
The reduction of oxygen content with pressure can be caused by the stress - related decrease of oxygen migration in N-implanted CZ-Si as well as by the effect of external pressure on a creation and growth of nitrogen/oxygen containing clusters serving as the nucleation centers for precipitation of nitrogen and oxygen.
