Multirate ideas for numerical time integration are explained concerning multirated extrapolation and stepsizing. Later parts of the report focus on Rosenbrock-Wanner (ROW) schemes, since those seemed to be most promising for the needs in circuit simulation: The ROW formula applicable to circuit di erential algebraic equations are introduced and changes within the analog circuit simulator Pstar ...

A proposed method to obtain the dose for Computed Tomography was evaluated on long a phantom, made of polyethylene. This phantom is 600 mm large. Adopting an empirical characterized function , tendency asymptotical grow by increase scanning length can estimate in infinite single axial rotation x-ray tube. The curve estimated different clinical protocols: tension, pitch, head/body, and center/pe...
