When the first impermeability data is taken down, the water pressure continues to be raised until the six specimens are all permeable and the first impermeability experiment ends.
The experiment data is shown in Table 5.
Therefore, when the mortar matrix is mixed with two materials, fibers not only have the ability of crack resistance, brittle reduction and shrinkage resistance, but also provide a basis for the better performance of SJ material’ properties, enabling the mortar matrix to own properties of high crack resistance and high impermeability.

It can be seen that the analytically calculated effective stiffness of the RSFJ after locking perfectly matches with the experimental data.
The data in Fig.8 suggests that having RSFJs in the roof has a minor effect on the base shear and the maximum inter-story drift.

As the critical void regions are located at the ends of the mold and that increased resin inlet flowrate causes a reduction in voids within the mold, was applied the method proposed by Lee et al. [26], using different injection points, in order to reduce the voids at the mold ends in the short period of time the idea is to obtain good finish quality of the composite after injection progress.
From the data obtained, although the injection configuration is different for the three cases, the total resin mass flowrate is the same in each case, and the resin and air volume fraction curves are practically the same.

This deterioration is represented in the model as a reduction of capacities of production lines.
Numerical Example A part of our data is based on the numerical example used in [7, 13].We define a planning horizon containing 8 basic production periods such that.

According to the data obtained, in the case of filling the PPS matrix with industrial glass fibers not treated with coupling agents, destruction is observed near the fiber surface; for fibers treated with γ-aminopropyltriethoxysilane, interfacial adhesion between the fiber and PPS is observed.
The functionalized polymer is obtained by treating PPS with a mixture of nitric and sulfuric acids, followed by reduction of the nitro to amino group according to the following scheme [44–46]: PPS containing side amino groups can also be synthesized by the method of nucleophilic substitution in the medium of N-methylpyrrolidone under pressure [47].
The data obtained are confirmed by SEM micrographs (Fig. 3).

Noise reduction is, for several purposes, a very challenging and complicated issue.
For analyzing ECG signals, data 100m, 104m, 105m, 119m, and 208m collect from the Physionet site under the MIT-BIH arrhythmia database.
Step 1: Read ECG signal xn from MITBIH data base and add noise vn to that signal to get a noisy ecg signal yn=xn+vn (6) Step 2: Apply EMD [10] to the noisy ECG signal yn then the decomposition is as follows EMDyn=pn=k=1Nckn+rNn (7) Where pn is the decomposed signal, rNn is the Nth residue and cknis the kthorder Intrinsic Mode Functions (IMFs).
