A Study on Double Bases Cooperating Mechanism in KDD ( I )

Yang Bingru,Wang Jianxin

Strategic Study of CAE 2002, Volume 4, Issue 4, Pages 41-51

Abstract:

This paper and paper ( Ⅱ ), aiming at the problems in the mainstream development of KDD, put forward a new academic thought that, in the knowledge discovery, the database can be restricted and deriven by the knowledge base whose structure can be in turn improved by the database. An open KDD system, KDD* , with double-base cooperating mechanism can thus be created. At the same time, the velocity, precision, and the auto-cognition of knowledge discovery can be imroved and the knowledge base is structurally equipped with the capacity of real time maintenance and to evolve by itself. This paper mainly deals with the corresponding relation between the database and knowledge base, which are the basis of double-base cooperating mechanism.

Keywords： knowledge node primitive knowledge base primitive database data sub-class structure doublebase cooperating

Cell-Zone Method: An Engineering Approach to Predict Smoke Movement in Large Scale Building Fire

Hu Longhua,Huo Ran,Liy Uanzhou,Wang Haobo

Strategic Study of CAE 2003, Volume 5, Issue 8, Pages 59-63

Abstract:

In large scale building fire, it is improper to predict smoke descending using traditional simple two-layer zone model, which divides the total space of the building into upper hot smoke layer and lower cool air layer. In this paper, an improved method, named Cell-Zone Method, is used to solve this problem, which first divides the total space into some small subspaces and then uses traditional two-layer zone model in each subspace. Comparison is carried out between these two methods in fire smoke development simulation in typical large space buildings by CFAST4.02 software package. Results show that Cell-Zone Method demonstrates more applicability than traditional simple two-layer zone model in large scale building, especially in buildings having large scale in one direction.
