Theoretical applications are made to estimate the SEA coupling loss factors between two subsystems connected by two rigid points.
In standard SEA calculations, however, only the statistical properties of the coupling stiffness terms are required.
The coupling loss factors between subsystems and can thus be predicted in a simple manner.
Eq. (10) has been used to predict the SEA coupling loss factors between two thin plates connected via two rigid points.
A simple expression on estimating the SEA coupling loss factors between the two SEA subsystems is deduced.

Introduction The main factors affecting the properties of aluminum matrix composites (AMCs) include reinforcement’s size, preparation process and mass fraction of the reinforcements [1].
Up to now, a lot of researches have been carried out about the effects of the content of mm-scale reinforcements on the microstructure and mechanical properties of metal matrix composites [7].

Resulting values vary and depend on many factors that significantly affect the interpretation of results.
The surface properties of pyrite play a significant role in the process of determining its separation from other minerals [3].
The most important surface property which affects the separation process is a wettability of the mineral surface [4].
In all other cases a measurement error was caused by random factors – drop spreading, different tilt of sample caused by a manipulation with the sample or the presence of dust particles on the sample surface.

Controlled cooling rate is essential in steel production in order to obtain the desired grades for specific mechanical properties.
The mechanical and metallurgical properties as well as the output of the process depend on the rate of cooling of the steel [1].
In this study Gaussian Process model has been used to estimate the cooling rate of the plate using the data for temporal variation of temperature for the entire cooling process and the generated data representative of the factors affecting the cooling of the plate.
The affecting factors include ambient temperature and convective heat transfer coefficient.

These studies pointed out that the degree of plastic deformation is a key factor to improve magnetic properties.
However, there are still many other process parameters that could affect the magnetic properties either positively or negatively.
Therefore, liquefy of Nd-rich phase would greatly affect the flow stress of NdFeB magnet.
There should be other factors that caused the significant decrease in iHc values.
Among all possible factors, the influence of heating method should play a decisive role.

According to Williams-Landel-Ferry (WLE) equation, FFV, which was affected by H-bonds, in turn affects the damping properties.
Dynamic mechanical properties In agreement with previous results from our study[10,11], H-bonds play an important role in determining the damping properties containing hindered phenols.
To explore the effect of H-bonding evolution on the damping properties of AO-70/NBR composites, DMTA was carried out to study the damping properties of the AO-70/NBR hybrids.
