This paper investigates projective invariants of geometric configurations in 3 dimensional projective space P, and most particularly the computation of invariants from two or more independent images. A basic tool in this investigation is the essential matrix defined by Longuet-Higgins ([10]), for this matrix describes the epipolar correspondence between image pairs. It is proven that once the e...

Part 2 continues the study of optimization techniques for elliptic control problems subject to control and state constraints and is devoted to distributed control. Boundary conditions are of mixed Dirichlet and Neumann type. Necessary conditions of optimality are formally stated in form of a local Pontryagin minimum principle. By introducing suitable discretization schemes, the control problem ...

Long-term (1 month) observations of waves and currents over a natural reef are presented which show a strong correlation between offshore rms incident wave height and cross-reef currents at subtidal frequencies. The energy spectrum of the cross-reef currents shows a significant peak at twice the semidiurnal tidal frequency, while the spectrum of sea surface elevation over the reef flat shows no...

This paper describes PICKERING, the semantic interpreter developed in the HIGGINS project – a research project on error handling in spoken dialogue systems. In the project, the initial efforts are centred on the input side of the system. The semantic interpreter combines a rich set of robustness techniques with the production of deep semantic structures. It allows insertions and non-agreement i...
