As the depth increases, the displacement decreases instantly; below the depth of 1.5m, the reduction amplitude of the displacement decreases gradually as the depth increases.
A DH5923 high-speed data acquisition instrument is set up for the signal acquisition.
Fig. 11 shows that damping ditch has a significant effect: 20 meters and 5 meters away from the tamping point, the reduction amplitude of the vibration acceleration are 59％ and 65％ respectively.

The analysis results showed that the structural behavior of fire-damaged RC beam was able to be simulated by using FE analysis with consideration of the reduction of material capacity due to fire.
On the structural side, enough test data to predict the shear behavior of element were not acquired due to the difficulty of test.
This can be converted to a reduced strength which will be data for structural analysis for the RC beam.

It can be concluded that the reduction of the moisture content of the grain, is considered very complex and, depending on the method and drying conditions, can substantially provokes breaking and cracks, which reduces final product quality.

By comparing the data between the two curves, it can be seen that the temperature of the drying air influences strongly the drying time, which can give rise to high temperature gradients in the solid, which induces thermal stresses and fast heating.

This rapid development in consequence affects a reduction on the ground water supply.
Methodology A quantitative analysis was used in this study and the required data are as follows: (1) the annual precipitation and (2) the water need of the inhabitants.

EN data was analysed in the time domain.
Also, Rn results are compared with traditional Linear Polarization Resistance (LPR) data.
The EN data has been traditionally analysed by statistical and spectral analysis method, where the data of this last method has been performed by Power Spectral Density (PSD) plots.
A sampling rate of 1 point per second was used and each measurement consisted of 1200 data points.

It was shown that a comparison of the data of change patterns in crystal-chemical parameters phenomenologically predicted and obtained from experimental data, allows to predict some of the conditions of stabilization in the examined phase, the solubility limits of alloying elements and, consequently, its homogeneity region, as well as formation conditions of multiphase systems.
For example, studies of Ti-Ni-Pd, Ti-Ni-Pt, Ti-Ni-Au alloys are thoroughly described in [13-21], the data on Ti-Ni-Fe and Ti-Ni-Co systems - in [22-27] and the data on Ti-Ni-Zr, Ti-Ni-Hf, Ti-Ni-Ta systems - in [28-33].
The availability of experimental data allows a detailed comparison of the predicted and experimental results.
Therefore, according to experimental data, the B2 phase existence region in the ternary Ti-Ni-Zr system may be represented as shown in Fig. 6.

Using comparative genomics and metabolic reconstruction strategies, a putative pathway was detected for C1 fixation consisting of four main steps: 1) conversion of carbon monoxide to carbon dioxide with gain of energy and/or 2) reduction of carbon dioxide to formate, 3) incorporation of formate to tetrahydrofolate and 4) donation of the carbon moiety of tetrahydrofolate to glycine to produce serine.
Using this genomic data, bioinformatics and comparative genomic strategies, we aimed to establish which genes and reactions could be implicated in carbon fixation in Ferroplasma spp.
Scheme of the CO2 fixation pathway reconstructed from partial genomic data of Ferroplasma genomes.
This prediction is compatible with some previous experimental data: according to the chimaeric pathway, these Ferroplasma strains need glycine specifically to fix CO2, and thus the amino acid is required in the growth medium, explaining why Ferroplasma requires low yeast extract for growth.

Experimental data are used to determine the most appropriate model which is in concordance with the permeant-specific parameters.
Various models analyzing diffusion and penetration mechanisms have been proposed to adapt the experimental data to diverse kinds of PCs.
When the formation permeability is too high, the permeation reduction factor is not important for many polymers.
Moreover, conclusions of researchers yield better information on the effects of polyacrylamide method on flow-induced adsorption and permeability reduction [51]. 5.

Such a reduction is in the range 12% ¸ 14%.
A reduction of 14% in the fatigue resistance of coated titanium specimens, or light alloy made components, is not so much relevant in applications were not only the fatigue resistance is the driving parameter but corrosion and wear resistance are of extreme importance too.
The model proposed by Murakami and Endo [22], based on the collection of experimental data for three-dimensional cracks and for short cracks (R=smin/smax=-1), gives the following formulation for the evaluation of the threshold stress intensity factor range: ∆Kth=3.3∙10-3HV+120Area1/31-R2n η=0.226+HV∙10-4 The parameter Area [mm], in the case of surface brittle films, may be assumed to be equal to the crack depth.
Due to the geometry of the spur gears, which present cut areas that enable the reduction of the mass of the gears, the whole gears, pinion and lead wheel, were modelled by means of a hybrid non-structured mesh made of linear tetrahedral and hexahedral finite elements.
The comparison of data confirms that the surface thin hard coating has a good effect on the fatigue resistance of gears, both for steel and Titanium ones.
