Finally, comparison of the failure modes between unreinforced and reinforced masonry walls reveals efficiency of using the rubber bearing isolation (passive control vibration devices) for a reduction in acceleration and an increase in the structural resistance to earthquake excitations [2].
It should be noted that all records are extracted from the data base of Iran's seismograph Site, affiliated to the Housing Research Center [5], and after applying the necessary corrections (Signal Processing) by Sesimosignal software.

Due to its latent heat storage, the applied PCM represents promising way for reduction of buildings energy consumption spent for heating and air conditioning.
Looking at bulk density and matrix density data, the low powder density of Micronal yields significant decrease of these both parameters for PCM modified plasters.

The results of local electron density calculated using positron annihilation data show that the local electron density of the systems is strongly changed by the Fe doping, and the local electron density vary noticeably at the range of O-T phase transition.
It can be seen from the XRD data that all samples have a single phase of orthorhombic structure.
When the doping content is so high (x ≥ 0.15), the Cu(2) in CuO2 plane will be substituted by Fe ion. on one hand, the number of clusters in Cu-O chain region increases[12], because oxygen cannot meet the coordination requirements, oxygen vacancies are increasing; on the other hand, some Fe3 + ions doped to the Cu (2) position, will increase oxygen vacancies in the CuO2 plane as well, can also cause reduction of valence electron density of the CuO2 plane.
The results of local electron density calculated using positron annihilation data show that the oxygen deficiency density of the systems is strongly changed by the Fe doping, and the positrons annihilate mainly around the Cu-O chains at low doping level, the positrons annihilate mainly around the CuO2 planes at high doping level.

In section 4, application to bearing fault data will be presented.
Data set A consists of 320 data samples of four different operating conditions with the fault defect size of 0.007 inches under four various loads (0, 1, 2 and 3 hp), where each of four operating condition includes 80 data samples.
Data set B also contains 320 data samples.
Data set C comprises 800 data samples including three different defect sizes of 0.007, 0.014 and 0.012 inches under four different loads.
Table 3 gives the classification performance on various data sets.

The literature adopts the scoring matrix dimension reduction technique to improve the data sparsity, but the method has higher time complexity in some large-scale recommendation systems.
The data set scoring data structure is shown in Table 1. 3.2.
The experiment adopts the five-fold cross-validation method, randomly selecting of the data set as the training set andof the data as the test set.
The filled data set are shown in Table 2.

X-ray diffraction data showed that the orthorhombic – tetragonal morphotropic phase boundary existed in all the samples.
According to the above results, it is revealed that a small amount of MnO2 doped in NKLNT ceramic has an evident effect on grain size reduction, as a grain growth inhibitor [5].

Therefore, In this study, a physics test model for tailings dam-break was carried out in hydrodynamic laboratory based on the design data of impoundments.
The reason of these phenomena is that with the reduction of the concentration, the static yield stress and viscosity of the tailings pulp both reduced in different degrees, it indicates that the resistance of the tailings pulp in motion had a decreasing trend. with the other conditions being same the tailings pulp have a farther movement distance, according to the formula (is adhesion depth, is static yield stress of pulp, is the bulk density, is flume slope), we can know that, for the weakening of the anchoring strength of flume, the depth of the pulp deposition gets smaller gradually.

These data suggest that bacteriocin LF-1 significantly reduced fruit decay and maintained overall quality, thereby extended the shelf-life of the strawberries.
This method is based on the reduction of DCIP with ascorbic acid in acidic solution [14].
