Decision trees for geometric models
Proceedings of the ninth annual symposium on Computational geometry - SCG '93, 1993A fundamental problem in model-based computer vision is that of identifying which of a given set of geometric models is present in an image. Considering a "probe" to be an oracle that tells us whether or not a model is present at a given point, we study the problem of computing efficient strategies ("decision trees") for probing an image, with the ...

Geometrical illusions: study and modelling
Biological Cybernetics, 1997The phenomena of geometrical illusions of extent suggest that the metric of a perceived field is different from the metric of a physical stimulus. The present study investigated the Müller-Lyer and Oppel-Kundt illusions as functions of spatial parameters of the figures, and constructed a neurophysiological model. The main idea of the modelling is based

Summary: A class of nonlinear \(\sigma\)-models coupled to gravity is defined by identifying the coordinates of spacetime with the components of a set of scalar fields. The obtained theories have purely geometric character and necessarily possess soliton solutions with topologically nontrivial scalar sectors.

Conceptual Geometric Modelling
2011This chapter starts with a review of existing spatial data models in the literature to show some key problems that need to be addressed by conceptual models to include spatial data and more generally geometric data. Motivated among other things by the need to support spatial modelling for the sustainable land use initiative we present a geometrically ...

New geometric modeller TIPS/GS for geometric simulation
Computer-Aided Design, 1986In spite of big expectation and long history, CAD/CAM systems based on solid modelling make slow progress. It would seem that something is wrong with the solid modelling technology. This paper describes how to open the way for advanced solid modeller. First, it is discussed what problems there are in present solid modellers.

In this paper, we present the Geometrical Loss Model. The GLM will allow for a tractable approach for CDO pricing and risk management. We introduce the concept of Base Volatility. We stress-test the model on the market data over the period 2005-2008, wich include the correlation crisis in 2005 and the recent credit crunch as well as the boom period of ...

There is a quotation at the beginning of this paper, mentioning the A. Robinson address to the ICM in 1950. According to it, ``contemporary Symbolic Logic can produce useful tools \dots{} for the development of Algebra and, it would appear, of Algebraic Geometry''. And actually the whole paper aims to explain how the recent progress in Model Theory has
