Hessenberg Input Normal Representations
Kurt Riedel
Every stable controllable input pair (A',B') is equivalent to an input pair which is in Hessenberg form and is input normal (AA^* + BB^* = I. (A,B) is represented as a submatrix of…

Scalings for Tokamak Energy Confinement
P. Yushmanov, T. Takizuka, K. Riedel +4
On the basis of an analysis of the ITER L-mode energy confinement database, two new scaling expressions for tokamak L-mode energy confinement are proposed, namely a power law scali…
