In this paper, a qualitative shape representation is described for the purpose of characterising linear geographical and artificial objects. In particular, we focus on the curve progression telling us how objects spread across the landscape. For instance, sinuosities of rivers provide important information about imperilled locations in the case of flood waters. However, precise geometrical desc...

Equation discovery is a very lively area of artificial intelligence which deals with explaining phenomena by mathematical formulae induced from the data. One successful approach to the problem are algorithms which construct thousands of formulae and report the simplest ones with the best fit to the data. Another, sub-symbolic, fits (piecewise) regression hyper-planes; their advantage is that th...

Blindsight is a neuropsychological condition defined by residual visual function following destruction of primary cortex. This almost universally held to include capacities for voluntary discrimination in the total absence awareness. So conceived, blindsight has had an enormous impact on scientific study consciousness. It reveal dramatic disconnect between performance and awareness used motivat...

I present in this paper a certain classification of objects with respect to their qualitative stability, i.e., with respect whether they change their qualities. The resulting classification is a flat typology of objects with two facets and three types in each facet. Assuming this classification the paper is then focused on one of these types: very weakly unstable objects. In particular, I discu...
