On the Practical Consideration of Source Localization Using the Location Template Matching (LTM) with Multiple Sensors Hong Jun Yang1,a, Sang Kwon Lee1,*,b and Ki Hong Shin2,*,c 1 Department of Mechanical Engineering Inha University, Incheon, South Korea 2 Department of Mechanical & Automotive Engineering, Andong University, Andong, South Korea.
On the other hand, the LTM method does not depend on the material property, i.e., it does not require to have knowledge on the structure whether it is isotropic or anisotropic.
Thus, in this section, we first summarize the basic property of the time reversal acoustics.
And the bandwidth of the signals and the length of signal are also found to be important factors for the LTM method.
Theoretically, the frequency bandwidth does not affect on the estimation of correlation coefficient if there is no noise.

Introduction Glass, with stable properties, is difficult to degradation.
So, temperature and pressure were the important factors affecting structural stability of the glass.
Glass powder was irregular granular, sharp edged, presenting fracture morphology under mechanical damage.

However, the Ti-6Al-4Vhas poor shear strength that makes it undesirable for bone screws or plates and also has poor surface wear properties which tends to seize when in sliding contact with its surfaces and other metals.
Schematic diagram Table 1.Material properties of the knee joint.
This factor is important in the design of meniscus.
It has been found that there are two main factors that influence the contact stresses of the UHMWPE meniscus; the material of the meniscus andthe friction coefficient µoccurred on the contact surfaces between the femoral and meniscus implants and between the tibia and meniscus implants.
In order to improve the knee joint design, these two factors need to be considered.

Optimum Design of the 3Z-II Planet Drive Based on Matlab Qilin Huang1, a, Yong Wang1, b, Maolin Xu1, Jungang Wang1, Zhigang Luo1 1School of Mechanical Engineering, Shandong University, Jinan, China akylinme@163.com, bmeywang@sdu.edu.cn Keywords: planet gear; 3Z-II; optimum design; nonlinear; MATLAB; Abstract.
The common 3Z planet drive has many good properties such as well-knit structure, light and large-transmission ratio.
Through the analysis above, we see that the independent parameters which affect the objective function are Za, b, m, xa.
According to mounting factor, we get Ceq1(x)=C1-(x1+Zb)/np,Ceq2(x)=C2-(x1+Ze)/np.
According to concentricity factor of modified gear pair of 3Z-II planet drive, we get Ceq3(x)=(x1+Zc)cosαb-(Zb-Zc)cosαa; Ceq4(x)=(x1+Zc)cosαe-(Ze-Zc)cosαa According to transmission ratio factor |ip-i|/ ip≤Δi, we get C1(x)=|ip-i|/ ip-Δi .

Usually, small grain sizes deliver superior mechanical properties.
This also affects boundary motion during recrystallization due to Zener pinning [2].
As atomic attachment kinetics are neglected within this approach, we utilize a dimensionless linear factor, to account for this, which is calibrated with the grain growth experiments of Zhou et al. [16] in C-Mn steel.
As both, the temperature dependence of precipitate coarsening at the HAGB and the free grain boundary mobility are equal [15,17], the pinned mobility is modelled as fraction of the free mobility with the linear factor, .

Introduction One of the modern surface construction directions is the construction of high-rise buildings, which is ensured by a current high level of building technologies, creation of construction materials with the relevant properties and quality, and structural mechanics achievements.
To ensure the stability of high-rise buildings for a long time, it is required to have a valid pattern of stresses in soil, as well as difficulties caused by influence of a large number of factors.
They include the weight of the building and the type of foundation, the nature of soil, its physical and mechanical properties, moisture content, availability or likely appearance of the other land or underground structures, power and frequency of aftershock, wind load, soil rheological properties, especially the terrain, etc.
Thus, the processes which have occurred and affected a structural unit of the general system can be called event .

Load is also reflected in the mechanical parts of the drive and transmission, where it can be measured using the strain-gauge load cell (sensors).
While comparing the results factors that affect the various different forms of measurement were eliminated.
Whereas the measurement was conducted as static, the filter did not affect the process of the measured values.
