| Research Abstract |
This project is a proposal to generate a "virtual laboratory" by showing an exemplar of intelligent integration of different computerized resources for materials design through computer network. This exemplar of virtual laboratory is an computational environment where we can share different levels of information for solution, materials design, materials selection, maintenance of artifacts, life cycle assessment and many future issues through computer networks.
The basic idea of materials design in this project is to prepare windows which confine solutions for each design requirement and preferably covers the materials complexity and diversity. Several approaches have been proposed, namely, first principles approaches, structure map approaches, functional maps, mechanism maps and sequences of material development experiences described by a set of production rules. In the process of integration methods will be needed to quickly and efficiently manage the growth, merge and perusal of mater

ials information. Furthermore, methods to identify extrinsic relations of significance will become mandatory to extract essential relations for each design problem.
All the possibilities that may prepare seductive computational environments for materials design are evaluated and as a set of core nodes for it, we select a library for first principles and calculated data of elements to predict electronical structures for different materials, crystallographic data bases, potential databases, microstructural databases and materials properties databases. How to connect data and knowledge between different structural layrs are illustrated in the activity of deriving and evaluating of interatomic potentials. This procedure shows the interactions between different knowledge bases to articulate suitable abstraction/parameterization to increase a predictability as well as an efficiency of calculation in materials design.
The big issue that comes after integration of different data and knowledge concerns the quality of collected information. In order to deal with this issue browsers with respect to time and space is developed as a prototype, where how to acquire knowledge through rescaling, rearrangement and pattern matching for classification is discussed and partly implemented as as system. This issue becomes serious in dealing with dynamic microstructural changes and basic concepts on time and space are analyzed and taken into accounts for a specification of the prototype system. Less
