But the numerical simulation is based on the theory and model which has certain assumptions and given parameters, so the calculation results will be directly affected by the selection of material model and parameters, the simplify of influencing factors and so on.
And stability control always simply relies on increasing the safety factor, which makes reliability lack scientific basis.
Due to the differences in rock and soil properties, some of energy would be stored as elastic energy (would be released at certain time), others would be dissipated in unrecoverable form.
Evolution of the system begins to be controlled by the dominant factor after adjustment.
As a result, self-organization function structure would be generated and each factor would tend to be cooperative.

Each of these models
has unique features and advantages, and choosing the right model for a particular application depends
on several factors such as accuracy, speed, and resource requirements.
The choice of an ASR model will depend on several factors, including the specific requirements of the application, the available computational resources, and the desired level of accuracy.
The objective of this experiment was to evaluate how the microphones' quality affect to WER of the models.
Investigating the impact of other environmental factors, such as the presence of other speakers, on the performance of automatic speech recognition systems. 5.

It assumes that the protected structure is equipped with sensors that monitor its response and/or loading conditions and with semi-active actuators, that is actuators that modify its local effective mechanical properties (e.g., yield stress).
An important factor is the application mode: multi-use valves (e.g., for landing gears) vs. single-use valves (e.g., for emergency airbags).
Fig. 5 illustrates schematically that the impacting mass and velocity affect the response of the impacted structure in essentially different ways, even at the same impact energies.

To conclude, for estimating the properties of polymer electrolytes in a battery, the transference numbers of Liions have to be known.
Table 1: Structure and properties of commonly used Li salts for studies on PEs.[39] Li salt Anion Main characteristics Ref.
Table 3: Physical properties of nitrile- and ether-modified disiloxanes.
However, gelled polymer electrolyte systems are popular because they merge the mechanical strength and stability of a polymer host system of choice with the ion solvating and transport properties of a liquid electrolyte, reasonably sacrificing ionic conductivity to improve safety and processability.

Each combination of components can affect the final properties of the resulting material.
The goal was to study the pozzolanic properties of expanded perlite.
Testing of physical properties of mortars.
This result is caused by two factors: (1) consumption of Ca(OH)2 by pozzolanic reaction; and (2) increasing time of curing the samples in semidry air.
After drying the final mortar properties seem to be favorable.

Because of finite space and funds, we could only finished one segment of PC beam for prototype model test with ratio of 1:3, so it was difficult to help us to grasp the local stress distribution and safety factor of crack resistance for the special beam construction.
Normally to apply uniform imposed weight on the model segment can make up the lose part, but the weight’s uniformity was difficult to complete and this measure would affect cracks’ observation in this experiment.
Therefore, when cantilever slab’s mechanical behavior was considered,to reduce cables tension force according to the calculation results was more appropriate.
For the large flange, the cross beam’s internal force in direction along the central line of bridge was significantly affected by the load conditions, support conditions and prestressing.
In summary, the one segment scale-down prototype model test for Jiayue Bridge confirmed the PC beam’s special construction and the concrete anchorage structure with adequate safety and crack resisting property.

Biofilm reactors use biofilm support medium -to provide surface for active bacteria attachment- with a density close to water so that it can be kept in suspension with minimum mixing energy provided by aeration or mechanical mixing [2].
Since the biomass primarily grows attached to the carrier, effective surface area of the carrier is the important factor [4].
These pollutants cause undesirable modifications to the environment that potentially affect human life [6].
The properties and types of selected biomedia used in the experiment are shown in Table 1.
