Each connected pair of nodes in a network Hollister Size Chart
can jointly produce one unit of surplus. A maximum number of linked nodes is selected in every period to bargain bilaterally over the division of the surplus, according to the protocol proposed by Rubinstein and Wollinsky [Equilibrium in a market with sequential bargaining, Econometrica 53 (1985) 1133–1150]. All pairs, which reach an agreement, obtain the (discounted) payoffs and are removed from the network. This bargaining game has a unique subgame perfect equilibrium that induces the Dulmage–Mendelsohn decomposition (partition) of the bipartite network (of the set of nodes in this network).
A parabolic approximation is developed for elastic waves, which depends on the variations in elastic properties being small and taking place slowly within a wavelength. The equations describe a wave which is, in a zeroth approximation, plane and which is diffracted by the heterogeneity by small angles only.The parabolic equation has well-known advantages over the original wave equations for numerical integration. In addition, the quantities to be calculated vary slowly over a wave length and numerical step sizes can be relatively large. The results are comparable with those of ray theory but, since they include diffraction effects, they are valid Hollister Canada
to a much greater range.
