Enhancement of Adjoint Design Methods via Optimization of Adjoint Parameters
Enhancement Adjoint Design Methods via Optimization Adjoint Parameters
2015/7/2
Three approaches of enhancing the Euler adjoint design methods using a non-linear gradient-based optimization package, SNOPT, have been investigated. First, the conver gence of Euler and adjoint solut...
The method of variation on parameters for integration of a generalized Birkhoffian system
Birkhoffian system Method of integration Variation on parameter Nonholonomic constraint Nonconservative system
2012/2/28
This paper focuses on studying the integration method of a generalized Birkhoffian system. The method of variation on parameters for the dynamical equations of a generalized Birkhoffian system is pres...
