Input data for constructing the database of each system was created using a data globe and 30,000 datasets were created.
Figure 1 Configuration of data sets in database using two cameras.
As mentioned in the previous chapter, each data set contains image pose ratios and image feature values from the cameras.
Input data for constructing the databases of each system was created using a data globe and 30,000 datasets were used.
As for the input data that is used for estimation, a bare right hand was placed in front of the camera (Firefly MV with wide-angle lens of View PLUS) and the left hand was covered with a data globe.

A (partial) carbothermal reduction of
alumina at 1550 ◦C was proposed.
In order to attain volume data of a sufficient resolution as well as an appropriate size (3D field of view (FOV)), the scans had voxel sizes of 2.7 µm.
During the reduction, the corresponding gaseous species and also CO formed.
Carbothermic reduction of alumina at 1823K: On the role of molten iron and reaction mechanisms.
Calciothermic reduction of TiO2: A diagrammatic assessment of the thermodynamic limit of deoxidation.

There are 96 complex data after QPSK modulation.
Insert a pilot every 8 data, so the number will change from 96 to 106.
The cyclic prefix is the copy of the 32 data at the end of the stream, and the cyclic suffix is the copy of the 32 data in front of the stream.
To match the data rate with the RF sampling frequency, the data must be up-sampled.
Between every two bits, we insert one 0 so that the data can be 2 times up-sampled.

The same authors have obtained reductions up to 50% of the HC emissions, using these pure biodiesel fuels.
Alam et al. [15] found a 60% reduction of HC with their biodiesel in a 6-cylinder diesel engine.
The experiments were started firstly with diesel fuel baseline data were recorded after the engine reached the operating temperature.
According to Lebedevas et. al. [23], RME has a reduction of HC emissions by 65% for all researched range of load.
RME has a reduction of HC emission up to 60.5%.

It is shown that the kinetics of softening between mill passes can be modeled more
simply when the normalized strain (reduction) per pass is employed rather than the conventional
strain.

When corrections to the downstream stands are made in this way, the pass reductions (and consequently the pass speeds) are changed locally causing further variations in the softening kinetics.
By contrast, with the θ-based approach, the value of the strain hardening rate in successive stands can be readily computed, the changes in the softening kinetics assessed and fed forward, and then the pass reductions corrected accordingly to minimize the variations in gauge and microstructure.
This allows for: 1) A radical reduction in the number of experiments required to generate sufficient data for modeling the post-deformation softening behavior; 2) A description of "strain accumulation" due to incomplete interpass softening in multipass hot rolling in terms of the strain hardening rate. 3) Significant simplification of the extrapolation of laboratory results to industrial high strain rate multipass processing.

Computational fluid dynamics (CFD) method was used and validated by comparing it with the experimental data presented in early reports.
Comparisons of CFD results and wind tunnel test data are shown in Fig. 2 and Fig. 3.
These figures show that lift coefficients fit the experiment data well, and error of drag prediction is with 10%.
It means that the fairing is good in reduction of pressure drag.
(2) Fairing at the root of horizontal tail is good for pressure drag reduction.

When water content, ω, was above the plastic limit, ωP, the reduction of shear strength is smaller.
The water content data show that, when the water content was close to the maximum molecular moisture content of soil, the loess began to collapse.
The measured data of unit water seepage loss was listed in Table 1.
In the absence of data, A=0.429, empirical value.
The results are as follows: a1=1.4 a2=-0.09 a3=-0.006 So the function of wetting front: (12) by (4), increment function of water content: , then, , after reduction, , the function of unit water seepage loss about time: The previous parameters was substituted into the above formula, and results were found out.
