The regularities and causes of changes (reduction) indicators of the quality of concrete with combined aggregate.
Structural analysis data with certain reliability allows to establish the influence of certain technological factors on the formation of the structure and properties of products and can provide effective control of production.
The obtained data confirmed the assumption that the presence of hydrate formations of cement stone on the surface of the combined aggregate, close in structure and chemical composition to crystallizing tumors, promotes the formation of strong isomorphic and epitaxial coalitions between calcite carbonate fillers and calcium oxide hydrate due to the proximity of the lattice parameters of these crystals.

Both Healthy and Faulty LRB conditions data were collected for 10 minutes each, which is adequate for 10 sets of data divided into training, validation, and testing with a fixed 6:2:2 ratio, respectively.
For example, [11] trained a U-Net model constructed by multiple CNN layers using the seismic field data collected at Hussar, Alberta, by the CREWES Project and found that the noise reduction obtained using their neural network architecture shows considerable promise in seismic data processing.
The SHM heavily relies on high-quality data, yet the real application environment and imbalance between good and faulty data collected become challenges in achieving high accuracy of predictive models [12].
Raw vibration data were acquired from both healthy and faulty LRBs.

Boyang Ding (1988) developed a liquefaction evaluation method of the shear-wave velocities based on the silt liquefaction data in Lingwu Ningxia earthquake (By Ding for short).
The shear-wave velocity data, soil data and results of the liquefaction evaluation with five methods are shown as figure 2.
Fig. 2 Results in-situ test of site sy25 and results of the liquefaction evaluation with five methods Compared with the shear-wave velocity data and soil data, the layer from 2.7m to 6m is recognized as the liquefied layer, the mean value of the layer velocities is 173.84m/s, the underground water table depth is 2.7m.
Case 2, site sy23, in intensity VII area, N39°23.117′ and E77°58.867′, liquefied site, the shear-wave velocity data, soil data and results of the liquefaction evaluation with five methods are shown as figure 3.

A finite element procedure is performed to acquire the data and this data is then correlated with beam theory model for initial verification.
This data is further evaluated to form the required model for calculating thickness of coating for a beam.
The resulting parametric correlation is verified through comparison with the already published experimental data available in literature.
Data points for the beam with the varying coating thickness are plotted and curve fitting on these VonMises stress data is applied in order to obtain the optimum relation for the coating thickness for the application on the beams.
The empirical relationship developed in this research is verified through comparison with the experimental data published in the literature [10].

It is well known that hot plume air recirculation and fan performance reduction will occur under windy conditions.
Fan performance reduction is also the research focus in the air-cooled condenser.
Meyer[6] simulated the flow field in the vicinity of an axial flow fan, and the comparison of the numerical results with experimental data indicates the accuracy of the fan model in its prediction of the axial fan performance characteristics.

When the elevated temperature was raised to 400°C, the reduction in compressive strength of Control concrete was 8.5 MPa, and the reductions of NC series specimen were only about 1-2 MPa, the experimental result revealed that adding nano-clay into concrete could significantly maintain compressive strength of concrete after high temperature exposure.
A positive relationship between strength and UPV is observed and linear regression curve was used to correlate the experiment datas.
A linear regression curve was used to correlate the experiment datas.

OFDM system model We consider an OFDM system that consists of N sub-carriers, each sub-carrier consists of data symbol X[k], where k represents the sub-carrier index.
There have been some useful threshold values for the use of noise reduction.
In order to compensate for disadvantage of conventional DFT-based channel estimation and to maximize the noise reduction effect at all sub-carriers, we consider Mahalanobis distance discriminant analysis estimation algorithm.

Third, the initial stage in the promotion of eco-building, the introduction of high-tech talent to resolve accounts, children's education and other personnel work, reduction of corporate income tax, and so policies to support the development of ecological building.In short, the state has extensive construction management industry by the former, as a high-tech industry to deal with.
The Assessment Criteria Need to Change .First, the data needs to be updated national scale, enterprise scale needs to be updated, the costs of ecological construction should have some improvement than traditional construction, in the current transitional phase, it is much easier to add eco-building standards.
Based on ecological construction development concept, investors should intensify policy, financing way, technology and research &development efforts, choose materials and techniques accord with national financial subsidies, which can make the cost reduction.
