    The authors investigate the layer assignment problem that occurs in the design of multichip modules (MCMs). An MCM is a high-performance compact package for the interconnection of several hundred chips, which are interconnected by several thousand nets. The aim is to place each net on an x-y pair of layers so as to minimize the number of such layers, with the constraint that the nets do not inters... View full abstract»

    The authors introduce a new matrix called the sign incidence matrix for Petri nets. Using this sign incidence matrix, they present a simple algorithm for generating all basis siphons and traps without first generating all siphons or traps. Any siphon (trap) can be expressed as a union of basis siphons (basis traps). The concept of siphons and traps plays an important role in the analysis of Petri ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (316 KB)

    The convergence of robot parameters is tested through the use of a globally convergent, adaptive control scheme for a complex, nonlinear robot system whose models are obtained by two different methods. The first is the classical Lagrangian method, while the second is based on the determination of minimal inertial parameters. It is shown that the convergence of minimum parameters in adaptive contro... View full abstract»
