The finite-element predictions are compared with experimental data including residual stress measurements using neutron diffraction.
Additionally the action of pre-loading causes significant plastic strains which may damage the material and contribute to a reduction in the fracture resistance of the material.

In order to get accurate threshold voltage drift data after high-temperature gate bias experiment, test of threshold voltage must be carried out immediately after the experiment.
Effects include reduced effective mobility due to reduction in the free carriers in the channel, decreased channel mobility due to coulombic scattering, obvious shift of the threshold voltage (VT), and stability of the threshold voltage.

CAD is short for computer aided design, which is a method of using computer technology to process datas in computer memory and to produce patterns in the displayer or plotters.The fields which utilize computer technology for visual design and production are regularly called CG(Computer Graphics) by the world today.
As a result, the similarities hinder the presentation of designers’ personalities and styles. 2.2.3 Reduction of comprehensive design quality Art design is a strong comprehensive discipline, the comprehensive quality of the designers determines the level of the design.
It is convenient to collect data in the early time of design, and easy to capture design inspiration, to save design schemes, and to deliberate design scheme.
While CAD emphasizes skilled operations of software and data and the fine data and modeling.

Dynamic Field Testing The ambient vibration test is an effective and convenient way of analysis to determine the dynamic characteristics of the building, which uses ambient vibration excitation to measure response of the building, by means of high-sensitivity sensor, amplification recording device and the random signal data processing technology.
After data analysis, the dynamic characteristics of the effect of small amplitude have sufficient accuracy[1].
The sensors of datum points did not move.
When seeking damping the data calculated by the INV damping method was stability, high accuracy, good repeatability, to make up for the deficiencies and shortcomings of the half-power law[2].
The calculated period after reduction was relatively large compared with the measured period.

The colloid and chemical bases on creation of highly effective multifunctional modifiers were developed on the basis of the experimental data in the field of chemical modifying of concrete compounds and concrete.
In general the stabilising effect of the surfactants is estimated by the degree of stability of the disperse system, modified by the data of surfactants, by the maximum surface, stabilized by surfactants in case of the given concentration and also by the limit concentration Ce.
Considering the available data on the structure, properties of plasticisers, their influence on colloid and chemical properties of mineral suspensions, the following requirements were offered to the oligomeric molecules in the study [24].
During the experiment the minimum quantity of the sulfuric acid, which was used at the stage of sulfonation, was determined by completeness of sulfonation and by absence of water insoluble impurities; the maximum quantity was determined by the beginning of reduction in MM intensity.

In the field of biotechnology, various computer bugs caused by round­ ing errors can induce an error interval that is too wide during data acquisition.
The set approach based on interval arithmetic is well suited in the biotechnology field because in these cases the error interval introduced during data acquisition is too wide as is also the case in biology, chemistry or medical sciences.
Constraint propagation on intervals allows on a predefined domain of variables, a considerable reduction in the size of a box [x] without resorting to bisections.
