687 Mathews, V. JohnEqualization of excursion and current-dependent nonlinearities in loudspeakersThis paper presents a novel equalizer for nonlinear distortions in direct-radiator loudspeakers in a closed cabinet by constructing an exact inverse of an electro-mechanical model of the loudspeaker.

690 Liu, FengEquilibrium shape of two-dimensional islands under stressWe show that the equilibrium shape anisotropy of two-dimensional islands in heteroepitaxial growth depends on island size, a consequence of the presence of strain. Even in homoepitaxy, in which the island shape has conventionally been equated with the ratio of step energies, a substrate surface str...Two-dimensional islands; Equilibrium shape; Heteroepitaxial growth; Homoepitaxy2000-08
691 Cohen, ElaineError bounded approximate reparametrization of NURBS curvesThis paper reports research on solutions to the following reparametrization problem: approximate c(r(t)) by a NURBS where c is a NURBS curve and r may, or may not, be a NURBS function.

696 Lindstrom, Gary E.ETYMA: a framework for modular systemsModularity, i.e. support for the flexible construction, adaptation, and combination of units of software, is an important goal in many systems.
