If you log on to the sys tenant and then execute theALTER SYSTEM CHANGE TENANTstatement to switch to a user tenant, the session-level variables obtained through a query are still the session-level variables of the sys tenant, but the global variables returned for a query are global variables...
When the individual PDFs of closely-spaced random variables such as natural frequencies of a structure overlap, generation of sample sets by assuming the frequencies to be independent random variables can lead to incorrect sets of frequencies in the sense that the frequencie...
Let Xi ,i = 1,...n be independent random variables with ranges in the set of non-negative integers, and each with expected value 1, but not necessarily ide... Let Xi ,i = 1,...n be independent random variables with ranges in the set of non-negative integers, and each with ...
Limit theorems in the set up of sumnation of a random number of independent identically distributed random variablesThe paper obtains unimprovable estimates of the rate of convergence in the law of large numbers for the weak and average metrics. The distances are considered on a set of ...
In this study, the velocity design variables are decoupled from the level‐set grid points. Making use of this property, we can adaptively change the arrangement of the velocity knots as the structural boundary evolves. This provides more design freedom in the optimization and allows for a ...
