查询词典 dynamic data exchange

The main research of the thesis is the implementation of batch data interchange function based on ETL. UDI has two main characteristics. First, by the separation of source systems and target systems, the platform provides data exchange among the systems to avoid point to point communication. Second, the data process of source systems is consolidated by platform based on the systems common requirements. The data extraction is implementated from the simple data exchange to the more complicated view of business logic.

Firstly, the equation for stress intensity factors under static uniform pressure is used as the reference case, and then the weight function for a thick-walled cylinder containing a radial edge crack can be worked out. Secondly, the dynamic stresses in uncracked thick-walled cylinders are solved under internal impulsive pressure by using mode shape function method. The solution consists of a quasi-static solution satisfying inhomogeneous boundary conditions and a dynamic solution satisfying homogeneous boundary conditions, and the history and distribution of dynamic stresses in thick-walled cylinders are derived in terms of Fourier–Bessel series. Finally, the dynamic stress intensity factor equations for thick-walled cylinder containing a radial edge crack subjected to internal impulsive pressure are given by dynamic weight function method.

Dynamic reliability under Littlewood-Paley wavelet is the biggest, dynamic reliability under modified meyerwavelet and harmonic wavelet are close.
