An advanced experimental-numerical hybrid technique was developed and applied to perform all the required data reduction tasks.
It comprises of an sectioning scheme called as the transverse/oblique slicing (T/O-S) technique and of a physically reasonable data reduction/smoothing procedure called as the global method (GM).
Raw 2D results Results for the exemplary raw 2D data as delivered by NIST are presented in Figs. 2-3.
In Fig. 4 results of its performance for the worst case of raw data for sample #1 (see Fig. 2 above) are shown.
Needless to say, the running thread belongs to that category so the data collected there suffers from this effect.

The miscibility gap in the pseudo-binary ZnFe2O4/NiFe2O4 system was modeled using equilibrium solution data.
We investigate this pseudo-binary system for which thermodynamic activity data exists [11].
These observations were quantified using fits to the EXAFS data.
Magnetization data from two different samples sintered under identical conditions confirmed this anomaly.
This happens at relatively low temperatures, as is clearly supported by the miscibility gap data.

Process Procedure and Recipe Process procedure Prewetting→ dye reduction→ leucen dyeing →oxidation →rinsing→ air dry.
Discussion Experimental data series were made in order to determine four kinds of different factors influence on K/S under the action of conventional and ultrasonic dyeing.
In the ultrasonic dyeing experiments, ultrasonic reacts on the process of reduction and dyeing of plant indigo dye, so that it is better for the reduction of dyes and dyeing.
Otherwise, the concentration was too low to guarantee stability of reduction on account of the lack of sufficient sodium hydrosulfite.
Finally, it achieves the goal of energy saving and emission reduction, increasing productivity and so on.

With analyzing of test data and searching the cause of abnormal noise and vibration, improvement measures were put forward and confirmed by bench test. 2 Noise and vibration test of rear axle Noise and vibration test of rear axle was conducted on automobile electrically controlled power-transmission system test-bed manufactured by Burkee of USA.
In this condition the meshing frequency of final reduction gear was 563.49 HZ and second harmonic was 1126.98 HZ, which was coincident with twice frequency of gear meshing.
In fact, the surface roughness of this drive gear and driven gear was twice lower than normal gear when checked, which should be strictly controlled when manufactured. 3 Improvement measures and test verification With analysis of the bench test data of rear axle, three improvement measures were put forward as follows: (1) Reduce the surface hardness of driven gear of main reducer from 60±2 HRC to 58±2HRC
With making sure the test conditions were coincident with previous test conditions, verification test of improved rear axle was done, and the test data was compared with previous data.
As the test conditions coincident with previous test conditions, verification test of improved rear axle was done, and the test data indicates that noise and vibration of rear axle was extremely weakened.

The results provide reference data relevant to ship design.
The polarization trends for all three alloys show the effects of concentration polarization due to oxygen reduction and activation polarization due to hydrogen generation.
The current density for passivity in anodic polarization is greater than that of dissolved oxygen reduction during cathodic polarization.
A potential of -900 mV (SCE) can also be included in the range at which concentration polarization occurs because the reaction involves the reduction of dissolved oxygen.
Cathodic polarization results in concentration polarization by dissolved oxygen reduction and activation polarization as a result of hydrogen generation.

The flanges were mounted on the input -, respectively the output shaft of the gearbox; for the data acquisition, three MP 60 modules (two for torques and one for the speed) were used [5].

DCT domain reduced image construction and SIFT feature extraction DCT transformation is an important mathematical basis of data compression standards such as JPEG, MPEG.
In the image matching experiment, experimental data come from the Mikolajczyk [3] data set, while in the image retrieval experiment, we used UCID data set.
Select eight images from each of the two data sets above, test the DCT-space fitting degree on the total 16 images, and calculate their efficiency upgrade degree.
Figure4.Determination of the reduction scale .
In the first experiment, firstly, extract the DCT domain and spatial domain SIFT feature for each two image samples of each image data subset, then match them.

Concerning mechanical properties of hydroxyapatite, there are many literature reports about the compressive strength of HA but a great variation between different research data can be found [7,8].
A Philips electronic diffractometer (X'Pert PW373/00 wide-range goniometer) with an XRG 3100 generator and DMS-41 data measuring system, theta compensating slit, and graphite diffracted beam crystal monochromator equipped with a copper target (35 kV, 20mA), nickel filter, and cintillation detector, was used to record diffractograms at a resolution of 2 o 2θ min -1.
Apparent density and the shrinkage after sintering (reduction in size), according to the compaction pressure applied, are presented in Table 1.
There was no significant difference between the two sample densities after sintering, although HA-1 sample presented a higher height reduction.
