Qualitative Representation of Planar Outlines
A new boundary-based scheme for qualitatively representing planar outlines is described, consisting of a set of seventeen “atomic” tokens, and based on a combined discretisation of tangent bearing, curvature, and the rate of change of curvature. By grouping together strings of atomic tokens, higher-level primitive curve tokens can be specified (PCTs), that correspond to localised curve features...
متن کاملQualitative similarity measures - The case of two-dimensional outlines
In this paper qualitative similarity measures are introduced. Depending on the underlying representation such similarity measures are based on specific qualitative distinctions which are frequently motivated by perceptual clear distinctions. Here, we discuss one such representation and show how it applies to different domains. In particular, qualitative methods are useful as soon as specific qu...
متن کاملSimplified qualitative chemical analysis for urinary calculi.
OXALATE Stone powder (2-3 mg) is moistened on an ordinary glass slide with two to three drops of 20% nitric acid and is slowly heated over a small flame to dryness and then for a further 5-10 seconds but without charring. The following results may be noticed: (a) formation of a conspicuous reddish-brown froth indicating ammonium urate; (b) formation ofa flat purplish-brown layer, evidence of ur...
متن کاملQualitative analysis of an autocatalytic chemical reaction model with decay
In this paper, we revisit a reaction–diffusion autocatalytic chemical reaction model with decay. For higher-order reactions, we prove that the system possesses at least two positive steady-state solutions; hence, it has bistable dynamics similar to the system without decay. For the linear reaction, we determine the necessary and sufficient condition to ensure the existence of a solution. Moreov...
متن کاملApplication Qualitative Process Theory to Qualitative Simulation and Analysis of Inorganic Chemical Reaction
In this paper, we explored the possibilities of embedding Qualitative Reasoning techniques, the Qualitative Process Theory (QPT), and its techniques in the field of inorganic chemistry. The targeted field of implementation is in the Chemical Qualitative Simulation and Qualitative Analysis. The QPT is used to model the chemical reaction, behaviors, properties, principles and commonsense reasonin...
