However, this solution produced a very high computational cost and the remeshing advantages were partially reduced from the degradation of accuracy due to the projection operation of the field variables from the old meshes to the new ones. To overcome these difficulties, the Element-Free Galerkin (...
These bearings are often used in harsh conditions and have high replacement cost with long delivery lead time. Therefore, it is important to monitor their condition at all times. Typical maintenance schedule is replace the bearings which have been in operation of set number of hours. However, ...
In considering the transportation, it can not only significantly reduce the space vehicle lift capability but also reduce the program cost. In the aspect of optical system design, the optical path length error of diffraction membrane optics is virtually eliminated when light passes through the ...
