Snow reference pressure is 0.3kPa, the distribution factor of snow pressure is 0.9.
With flexible coefficient reducing, frame inclined beam axial force declined but changed slightly; while the axial force is very small for the horizontal frame beam, it is not necessary to consider the affecting of flexible coefficient.

Introduction The metallurgical characteristics and final mechanical properties of a casting are directly related to the shape, size and distribution of the graphite present in the matrix [1,2].
The inoculant affects the nodule count (Ce inoculant seems to be the most effective for low Ti versus ZrMn inoculant for high Ti) but the influence on the nature of the nuclei is not significant in most of the cases.
The content of titanium in the iron also affects the sequential growth of the nuclei.
For the particular case of the 0.02-0.03% Ti irons an additional contributing factor is the presence of Zr in the Ti(CN) inclusions.

Introduction It is now known that ultrasonic irradiation affects the defect structure and electrophysical characteristics of semiconductors.
Similar studies were carried out in detail for Si (Li) -p-i-n detectors [1, 2], where it was shown that the energy resolution is significantly affected by irregularity of the silicon resistivity.
Taking into account the above, the electric field amplification factor can be calculated as follows.
There is a zone of mechanical stresses around the formed concentrations of such impurity atoms.

Compared with the traditional optical or mechanical stabilization techniques, EIS has advantages of real-time processing speed, high accuracy and easy implementation.
In Kalman filter, different process noise and measurement noise values will affect the filtering result.
The improved sage-Husa adaptive filter proposes the criterion [19] using the property of innovation sequence to determine whether the filter is divergent.
Zhou [20] proposes an improved sage-Husa algorithm based on covariance matching and attenuation factor.
In some camera systems of high dynamic application such as the real-time weapon targeting system, EIS is the secondary treatment after optical or mechanical stabilization.

Introduction The evaluation of the microstructure development during and after hot deformation of metals has practical importance due to its relationship with the mechanical properties of final products.
Flow stress during the hot rolling simulation process In order to validate the flow stress obtained on the basis of given flow curves, rolling forces during the hot rolling simulation and laboratory rolling test were compared for finishing rolling stages, as the flow stress is normally the most important factor affecting the rolling force during finish rolling (Fig. 10).

Known amounts of enzyme preparation were transferred to several polypropylene vessels, each containing 1 mL 5 mM potassium phosphate buffer pH 6.5 and a small mechanical stirrer.
Since the surface properties of the PHD would change with the pH environment, as an important factor affecting the binding and activity yield of immobilized enzyme, the process of immobilization PGA was studied.

Cathode material is an important factor that determines the capacity and life of a battery [2].
Their coating improved the cycle performance and storage properties of NMC811.
This indicates that the coating of rice husk derived silica to commercial NMC811 surface does not affect its crystal structure.
Characterization using XRD shows that silica coating does not affect the NMC811 crystal structure.

IPMC actuators, also known as artificial muscles, possess extraordinary properties such as low efficiency consumption, compliance, bio-compatibility and ability to be miniaturized.
Here the solid bodies; wing and fin are suppressed and only fluid bodies are meshed with the following properties: solver preference CFX, use advanced size function (off), smoothing (medium), transition (slow), and span angle center (fine).
We specify mesh behavior option of soft which means that the size control will be affected by proximity, curvature, and local remeshing during the meshing process.

Compared with the traditional crystal materials, bulk glassy alloys (BGA) as a new class of materials have extraordinarily distinct advantages in magnetic, chemical and mechanical properties due to the lack of long-range order in their atomic arrangement[3].
They showed that the amorphous phase in the coating contributed to surface hardening and improved tribological properties.
Elemental powder blends with nominal atomic percentage compositions of Zr55Al10Ni5Cu30 premixed evenly by a ball mill in an Argon-gas atmosphere for 5 h was chosen as clad materials due to its well-known glass forming ability as well as its outstanding properties [12].
It is believed that the relatively strong corrosion properties of sample A is related to the presence of excellent corrosion-resistance of amorphous phase, which has a high amorphous phase content at the surface produced by the last laser remelting process.

There was the ease of their generation from various energy sources such as: mechanical, thermal, nuclear and chemical heating.
Today there is a great encouragement and decision by opting to increase the supply of electricity by new hydroelectric and thermoelectric plants, even if it affected the high cost and long-maturity assets outside the hydrological risk that this option has been threatening, ending with a complex composition costs and tariffs whose abstraction rises within the legislature [3].
