Electromechanical machines are based on a variable-speed electric motor; a gear reduction system; and one, two, or four screws that move the crosshead up or down.
The stress strain diagrams were monitored for all the test specimens and test data were recorded.

The measurement Review and data analysis Normally the rating of sound insulation of windows is accomplished by using the weighted sound transmission index according to IS0 717, Rw.

Experimentally, it is rather difficult to apply a prestrain with the conventional tests and very few experimental data exist [4].
On the other hand, Fig. 6 shows that a low equibiaxial prestrain (2% or 5%) can lead to a significant reduction of the formability, especially in the critical zone of the plane strain state in which the major strain presents a minimum.

Graphical response S/N for all three factors ANOVA Analysis Total sum of squares Sum of square is a measure of the deviation from the mean value of the data, [8], and can be calculated with the equation: (4) Where: n – total number of experiments; Yi – value of results of each experiment.

When R2 value is between 0 and 1, closer to 1 indicates that the model can effectively reflect the experimental data, R2 = 0.9956 means that 99.56% of changes of response surface can be predicted by this model.
The affection of various factors on COD removal rate can be ranged as: current intensity>aeration>pH value. 2.3 Analysis of two factor interaction effect Dimension reduction analysis with the date in the table 3.

Data from JCPDS-International Centre for Diffraction, the lattice structure of commercial powder LSCF was orthorhombic with space group Pbnm.
The homogeneity of particle of each element was very important for each of the elements functioning well during oxidation reduction process as well as increased the effectiveness of electrochemical reactions that takes part in cathode [7,8].

The experimental data were used to develop the procedure facilitating the control over the speed of silver azide decomposition by means of additional introduction of impurities.

Figure 2A summarized the DOA, relative water adsorption (RWA) and contact angle measurements and the data are summarized in.
However, the slight reduction in contact angle indicate that the membranes with 22-23 wt.% of acetone are moderately hydrophilic but with tight and smaller pore size, thus explaining the high rejection with nominal permeation rates observed [6].

The temperature was maintained at 25±0.1℃.Data were obtained by means of a PC driven potentiostat.
In ref.[7],the study showed the cathodic character of the Al(Mn,Fe,Cr) precipitates causes the reaction of oxygen reduction to be produced on them.

The reduction in Young’s modulus value is due to decreased in solubility of NFF in RC biocomposite films.
