The Use of the Metric Diagram in Qualitative Kinematics

چکیده

A promising approach to qualitative reasoning about mechanism kinematics is the theory of pace vocabu:aries . In this paper, we propose a new method of computing the place vocabulary representation . The computation is split into the combinatorial manipulation of the symbolic information, and the evaluation of predicates on the metric dimensions by an abstract device, the metric diagram . This abstraction allows reasoning about mechanism behavior without reference to an explicit representation of the numeric dimensions of the parts. When the metric information is incomplete, the solution may contain ambiguities. When no metric information is available, the result is an ambiguous, but purely symbolic, place vocabulary . This provides an existance proof that purely symbolic spatial reasoning is possible .

Availability evaluation of Software architecture of object oriented Style using coloured Petri nets

Software architecture is one of the most fundamental products in the process of software development in the areas of behavioral or non- behavioral features like availability or transformability change. There are different ways to evaluate software architecture one of which is the creation of application model. An executable model of software architecture is an official description of architectu...

Qualitative Kinematics: A Framework

Qualitative spatial reasoning has seen little progress This paper attempts to explain why We provide a framework for qualitative kinematics (QK), qualitative spatial reasoning about motion We propose that no general-purpose, purely qualitative kinematics exists. We propose instead the MD/PV model of spatial reasoning, which combines the power of diagrams with qualitative representations Next we...

Arrangement" An Aspect-Graph like Qualitative Relation for Medical Tomographic Images

In this paper we propose a qualitative spatial relation called "arrangement" which serves to identify medical images obtained from similar tomographic sections. "Arrangement" describes the sequence in which neighbors of each part are situated around it in the image. "Arrangement" is closely related to the Voronoi diagram of the parts. Based on the Voronoi diagram a metric for comparing "arrange...

Assessment of the Log-Euclidean Metric Performance in Diffusion Tensor Image Segmentation

Introduction: Appropriate definition of the distance measure between diffusion tensors has a deep impact on Diffusion Tensor Image (DTI) segmentation results. The geodesic metric is the best distance measure since it yields high-quality segmentation results. However, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. The main goal of this ...
