A summary of the deposition data and set descriptions are
given in Table 1.
CV hysteresis measured was also reduced for all the sets (Fig.1) with the largest, 95% reduction to the value of 3×10 10 cm-2, for the W0 sample from Set 4.
The reduction of the leakage current is most probably caused by the negative charge that originates from the AlON/SiC interface states and polarization in the AlON layer, leading to an extension of the depletion region.

Vanderbilt-type ultrasoft pseudopotentials [8] and the local functional Ceperley and Alder data as parameterized by Perdew and Zunger (CA-PZ) [9] are chosen.
With increasing x, AFM lattice constant suffers a slight reduction by comparing with that of corresponding FM alloy, resulting in significant enhancement of AFM superexchange interaction, in which the coupling between AFM atoms is mediated by nonmagnetic atoms.
The calculated lattice constant of FM follows the Vegard law well while that of AFM suffer a slight reduction as x>0.5.

Using realistic data, the following example is provided to highlight the solution process for an allocation problem.
The benefits such as ability to perform complex operations simultaneously by several arms increase of work cell reliability by sharing of responsibilities, reduction in space by space-sharing, increase in system flexibility by shared manufacturing and material handling resources, and reduction in cycle time by concurrent work amply justifies the use of multi-robot systems in industries.

Cleaning of data was performed according to a confidence
index higher than 0.1.
This result allows to suppose that a strain-induced mechanism of martensite formation is actually operating and that the reduction of the packet size in the central region is the consequence of the activation of a higher number of martensite nuclei per unit volume compared with the sub-surface zones.

According to the data provided by a Cranes Machinery Co., LTD. and the relevent specifications [5-6], the loading method of strength check for the crane is as follow: wind load, 1.55×vertical and lateral loads on the main girders and 1.16×dead weight of the crane.
Compared with the reconstructed crane, the displacements in the x direction have a reduction of 68.6%, 70.1% and 70.5%, respectively.
Compared with the displacements of the reconstructed crane in the z direction, the displacements of the crane strengthened by Scheme 4 have a reduction of 49.1%.

The data of oscillation decay were collected automatically by two
phototransistors connected to a computer.
We can observe in the figure a reduction of elasticity modulus with the increase of corn starch content.

To calibrate the raw SCM data to concentration, the buffer layer and the
epitaxy were used as reference concentration levels.
Fig. 1(c) shows a strong reduction of the roughness and a suppression of step bunching when using the capping layer (RMS=0.33 and 0.38 nm for the lower and higher fluence, respectively).
On the contrary, capped samples show a more preserved and flat surface, and the suppression of step bunching can be explained in terms of a reduction of atom diffusivity on the surface and of Si evaporation during annealing.

The introduction of filler into polymers has become a trend among researches owing to the excellent enhancement of the resulting composite properties, reduction of the total cost and improvement in the processing characteristic.
The shape fixity however decreased in 5 wt% clay filled TPU in line with the shape recovery data.
As for the reduction in shape fixity, the presence of excess clay may interrupt the crystallization behavior of PCL chains during cooling.
