We define a new algebraic form for Boolean function representation, called EXOR-Projected Sum of Products (EP-SOP), consisting in a four level network that can be easily implemented in practice. Deriving an optimal EP-SOP from an optimal SOP form is a NP NP -hard problem; nevertheless we propose a very efficient approximation algorithm, which returns, in polynomial time, an EP-SOP form whose co...

But following the 1992 EPACT deregulation, block ownership in utilities increased sharply, relative to a matched sample of non-utilities, which already had large blocks by the 90s. The post-EPACT blocks in utilities were...

Gemeenskapsdienste word gelewer vanaf gedesentraliseerde poli-klinieke wat met die hospitaal skakel. Gesinsbeplanning is ’n aspek wat baie aand...
