In this paper, we introduce the design and experiments of project for Integrated and Agent Retrieval System to classify domain digital resource of diseases and diagnoses. According to the domain ontology of disease and diagnoses, the modelling, constructing and application of Ontology in this project will service for agent retrieval and knowledge-based management, which present the application of...
Water content in crude oil is a very important data in oilfield production logging system. It is also an indispensable parameter for the research of its development prospect. During the process of exploitation, storage and transportation of oilfield, high accuracy measuring of water content in crude oil can optimize production parameters and improve oil recovery rate. The GRNN (general regression...
Bi-temporal conceptual data model (BCDM) expresses bi-temporal mechanism effectively, which achieves the two-dimensional expression about virtual time and transaction time. Based on standardization of the temporal label in BCDM, the paper expresses temporal information based on RDBMS (relational database management system) snapshot model, then analyzes which normal formula can be expressed in BCDM,...
Because of insufficient cash flow and technical issues, small & medium shipping enterprises in China are not able to provide integrated logistics service that leads them to be in a disadvantaged position in the market. This paper introduces the concept of shipping virtual logistics business and establishes virtual logistics enterprises partner choice evaluation index system for small & medium...
In current distributed data stream management models, data should be transmitted on time among many computers through overlay network, which contains only logical topology information. For lack of real topology information, it is hard to control data delay. To solve this important problem, the requirement to process data stream in distributed networks is analyzed in this paper. Chord and super cube...
