A Specification Language and System for the Three-Dimensional Visualisation of Knowledge Bases
نویسندگان
چکیده
In this paper we present models and languages to specify 3D interfaces for accessing knowledge bases. In this approach, a specification has an abstract and a concrete level. The abstract specification language describes the contents of nodes, obtained by selecting knowledge base objects, and different categories of links on these nodes. It serves to generate an abstract interface which is a 3D spatial hypertext. The concrete specification language associates styles and layout managers to the abstract interface components, so as to produce a concrete interface in which the nodes have a presentation and a position. This concrete interface is then easily translated in a 3D scene representation language such as VRML or X3D to be displayed.

Constructing Two-Dimensional Multi-Wavelet for Solving Two-Dimensional Fredholm Integral Equations
In this paper, a two-dimensional multi-wavelet is constructed in terms of Chebyshev polynomials. The constructed multi-wavelet is an orthonormal basis for space. By discretizing two-dimensional Fredholm integral equation reduce to a algebraic system. The obtained system is solved by the Galerkin method in the subspace of by using two-dimensional multi-wavelet bases. Because the bases of subs...
متن کاملDevelopment of software in the study of carotid artery in the neck.
The aim of this work was to develop and employ software for the study of the common carotid artery and its branches in the neck. We first constructed geometric models of anatomic components, for the building of knowledge bases to be used in automatic feature extraction techniques from images. Then, we developed a software system characterised by three-dimensional visualisation, image processing...

متن کاملPredicting three-dimensional displacement around the tunnel and its impact on the value of Q-system
Having knowledge of stability of an underground space depends on stresses and strains around it. Creating underground tunnels leads to significant changes in the rock mass stress. Therefore, to achieve the necessary stability, stresses and deformations around the tunnel must be examined carefully. Usually, stress-strain behavior analysis is conducted in two-dimensional mode. This paper was cond...
