From Fig.6 and Fig.7 the previous comparison results can be seen, in the same material, size,and the same gravity loads under these conditions, 22 upper 8 node combined after the settlement of displacements and stresses are greater than when not settlement.
Design of superstructure foundation and when considered separately, in order to meet seismic bearing capacity of structure shall increase the strength of materials.

However, so far there has been almost no publication in this area on the prestigious scientific journal focused on optimizing this process.
Coconut oil is a favorite raw material in personal care products of natural origin, and this is the main raw material that Ben Tre province is focusing on to diversify its products.
Materials and Method Raw Materials and Chemicals Crude coconut oil was collected in Ben Tre (Vietnam), which the physical and chemical parameters are checked and meet the standards of Vietnamese (TCVN 7597: 2013) such as relative density, refractive index, saponification value, value iodine.

Especially, the topology optimization is referred to as the FE-based techniques for an optimal distribution of void and materials [5].
The approach presented in this paper is This research is supported by the National Natural Science Foundation of China Grant#50675027 simulated through ANSYS to verify the effectiveness and feasibility.
The assumption that the material density and material properties of the non-linear relationship as follows:    = = 1 1 vv EE a η (2) Where 1E is the elastic modulus of the actual material ( 1>α ), 1v is the Poisson's ratio.
And then we elected the material properties of the robot arm.

One of the widely studied materials is cobalt ferrite (CoFe2O4) MNPs because their magnetic anisotropy value is higher than Fe3O4 and γ-Fe2O3 [6].
These nanoparticles have a potential to be used in various applications, for example in biomedical magnetic materials as soft magnetic material acting as carriers in drug delivery [8], magnetic fluids [9], catalysts [3] and other applications.
