Current environmental monitoring systems assume particles to be spherical, and do not attempt to classify them. A laser-based system developed at the University of Hertfordshire aims at classifyingâ€¦ (More)

The HyperNet (Hypercube based neural Network) architecture uses higher-order sigmapi units which are realisable with conventional memory technology. Real-valued node input and output vectors promoteâ€¦ (More)

This paper describes a numerical realization of an extended continuous Newton method deened by I. Diener. It traces a connected set of locally one{dimensional trajectories which contains all criticalâ€¦ (More)

We introduce the basic notions of Automatic Di erentiation describe some extensions which are of interest in the context of nonlinear optimiza tion and give some illustrative examples

Consider a computation F with n inputs independent variables and m outputs dependent variables and suppose that we wish to evaluate the Jacobian of F Automatic di erentiation commonly performs thisâ€¦ (More)
