Data have been grouped by Ge target concentrations.
While the N-doping concentration increase leads to a reduction of the forward voltage drop VF and of the blocking voltage VBR of the MPS diodes, no significant impact of the Germanium co-doping can be observed.

Based on the data in Table 2, it is noticed that the values of crystallization enthalpy decreased with the increase of PPS segments, indicating that the incorporation of PPS segments restrict the crystallization of PBS.
The diameter of the spherulites of copolyesters decreases with the PPS segments increasing and the spherulites become less clear due to the reduction of the crystallization ability after incorporation of PPS units.

Subsequently, the material was heated at 800℃ for 30 minutes and pack rolled from an initial 0.12 mm thickness to 0.11 mm with a reduction of 8.3% in order to get the dense electrical steel.
The experimental data were analyzed using a least square computer fit assuming Lorentzian peak shapes.

Moreover, on the basis of basic electrical characterizations, a further reduction in band offset has been pointed out for the SiC-MOS devices fabricated on high mobility C-face channels [3].
Peak deconvolution of the Si2p spectra revealed that the intermediate oxide states at the interface increased as the oxide thickness increased (data not shown).

Introduction
The ESP implementation of the electronic fire signalling (hereinafter referred to as EPS) in the buildings shall be considered on two levels:
1 signalling (EPS) required in compliance with the legislation in force exists or not
2 if EPS is required by the legislation in force, then it is necessary to have a project of fire protection comprising all essential data for the EPS implementation in the building.

The total bits reduction in the 2.4kb/s speech coder comes from the new LSF quantization scheme, which lowers the number of bits needed to represent the LPC filter from 25 to 19 bits, at no extra cost in terms of storage or complexity.
The 2.4kb/s speech coder, through model and LSF quantization improvements, outperforms the MELP coder at 2.4kb/s transmission rate [5], making it an attractive candidate for wireless communications and other low data rate applications.

The main effect plot is essentially prediction profile plots showing how the mathematical model that is fit to the DOE data [5].Fig. 5 shows the main effect plot.
The conclusions are as follows: Compared with the original model, through the optimization, the aerodynamic drag coefficient of optimal model achieves a reduction of 10.56%.

The effect of the pre-strain on these strengths was almost the same as hardness data shown in Fig. 2.
Strength increase and aging time reduction by pre-strain are thought to be by an enhanced Cu-cluster precipitation reaction at the extra vacancies introduced in straining.
