3-D building reconstruction with ARUBA: a qualitative and quantitative evaluation
(1997)Automatic Extraction of Man-Made Objects from Aerial and Space Images (II)Reliable and accurate 3-D reconstruction of man-made objects is essential for many applications using digital 3-D city models. Manual reconstruction of buildings from aerial images is time consuming and requires skilled personnel, hence large efforts are being directed towards the automation of building detection and reconstruction. In this paper we present ARUBA — a framework for automated 3-D building reconstruction. After highlighting ...Conference Paper -
Image-based reconstruction of informal settlements
(1997)Automatic Extraction of Man-Made Objects from Aerial and Space Images (II)The improvement of living conditions in informal settlements (IS) is one of the most complex and pressing challenges facing developing countries. In this paper we report on progress towards the automated generation of geospatial databases of informal settlements from large scale, low cost, digital still-video imagery. We focus on shack extraction as the predominant data requirement. In contrast to western residential environments where ...Conference Paper -

Set-up of a biocontrol experiment with genetically characterized hypovirus-infected Cryphonectria parasitica strains
(1998)IOBC-WPRS Bulletin ~ Workshop Proceedings Molecular Approaches in Biological ControlFor a better understanding of its dissemination, the Cryphonectria hypovirus has been artificially introduced into two different C. parasitica populations. Chestnut blight cankers were treated with a hypovirus-infected strain. In one population (Choex, Valais) hypovirulence was absent before the treatment, whereas in the other (Claro, Ticino) it was already naturally present. The aim of the experiment was to track the introduced virus as ...Conference Paper -
Capturing nonlinearities with perturbation models
(1997)IFAC Proceedings Volumes ~ IFAC Symposium on System Identification (SYSID'97)This paper investigates the use of robust control perturbation models for describing nonlinear systems. We use model validation techniques to find the smallest linear dynamic perturbation required to describe a particular behaviour of a nonlinear system. The Moore-Greitzer model of rotating stall in jet engines is used as a detailed example.Conference Paper -
Emissions and performance tradeoffs for advanced marine diesel propulsion
(1998)IFAC Proceedings Volumes ~ Control applications in marine systems : a proceedings volume from the IFAC conferenceA multivariable control scheme is designed that reduces smoke generation on an experimental marine Diesel engine equipped with a variable geometry turbocharger (v). The variable geometry turbocharger allows the improvement of the steady-state ship hydrodynamic and propulsion characteristics and requires coordination with the injected mass fuel to achieve a good transient performance.Conference Paper
