A structural reinforcement for insertion into a cavity of a vehicle structure including a base reinforcing portion, an expandable material and a localized reinforcement is disclosed. A simulator obtains a plurality of slices of a MOS gate, the slices each comprising at least one parameter, the parameter comprising a slice gate width and a slice gate length. This structure is capable of performing either a polar operation or a Cartesian operation and can dynamically switch between them depending on the instantaneous value of a metric measured by a thresholderrouter.
