Data will
be presented from the undamaged specimens.
These methods compare the eigenvalues and eigenvectors calculated with, let's say, a finite element model with measured data.
This data are used both as reference figures and to develop a most accurate finite element model.
Obtain a reduction-expansion matrix in order to expand measured data and error vector to the size of the FEM model, in order to represent them on the model, to make a friendly interpretation of mode shapes and damage location. 2.

The hot-rolled plates were symmetrically cold rolled to 65-95% reductions in thickness and then asymmetrically warm rolled to 20-40% reductions by one pass at 473 K with a roll speed ratio of 1.5.
To reveal a change in texture during solution treatment, the area fraction of representative orientations were determined from EBSD data by using the samples annealed at 813 K for some short periods within 90 s and immediately water-quenched.
The near-{111}<110> recrystallization texture, which has a peak in the center of a {111} pole figure, is formed at relatively low reductions of AWR, while the {111} orientations hardly develop at all CR reductions under the condition of 40% AWR reduction and the main component is expressed by {013}<631>.
Here C90A25 means cold rolling to 90% reduction and asymmetric warm rolling to 25% reduction.

Furthermore,
the magnitude of this current-induced recovery is dependent upon the injection current, as reductions
in the current cause a slower, but larger overall Vf drift recovery.
While numerous samples have been studied to date, data from two samples, D14L and D30R, with a moderate and high density of BPDs, respectively, are presented.
The solid lines represent least squares fits to the data using eq. (1).
b) Temperature dependence of sat fV∆ using data collected at 25 A/cm 2 along the various IV traces (solid squares, left axis) and sat Q (half filled circles, right axis).
This implies that while the steady-state balance between SSF expansion and contraction is changed to favor increased contraction by reducing the injection current, the reduction in current also causes a reduction in the ehp recombination rate and therefore slows the SSF movement, thereby causing the increase in the time required to reach a new steady-state sat fV∆ in the current-induced recovery experiment.

The experimental results show that the most important factors in nanogap reduction were the metal type and the initial nanogap.
The reduction of nanogaps after the lithography process, as discussed earlier, is a SB quality characteristic.

In order to guide and standardize energy efficiency benchmarking in cigarette enterprises, promote energy-saving emission reduction work, this paper researches on how to structure the energy efficiency index system reasonably and scientifically.
The application practice shows that the energy-saving rate can reach over 18%, and continue to promote energy-saving emission reduction of cigarette enterprises through carrying out the energy-saving reform on the basis of reasonable application of the energy efficiency index system.
The State Council issued the “energy-saving emission reduction 12th five-year plan” in 2012 to clearly demand to carry out of thousands of enterprises energy saving and low carbon action, to conduct energy efficiency benchmarking activities and to improve China’s total energy efficiency.
General principle: determined index should be professional data which is general, common, and easy to obtain.
Those indexes mainly affect material quality, thus affecting indexes of energy consumption and emission reduction.

The simulation result can make us understand the mechanism of the
void-growth at the interface framework and provide data base for improving reliability of package
and optimum design
Introduction
Packaging has a dominant effect on electronic system cost, performance, weight, size and long term
reliability.
Recent years have therefore seen rapid developments in packaging to meet the challenges of miniaturization and cost reduction while delivering increased electrical performance and reliability.
The vapor pressure and the reduction of the interface strength at high temperature due to the previous moisture intake will cause local interfacial delamination of the package and eventually result the package crack to failure (popcorn failure [1]).
Moisture vapor pressure and the reduction of the interface strength at high temperature cause local interfacial delamination.
FEMB was used as pre-processor to generate the geometrical model and produce the mesh and as the post-processor for results visualization and data acquisition.
