This article systematically discusses principle and accomplishment method of the technology for the asymptotic image compressing coding,introduces the apply of the coding technology in the system of remote visual malfunction consultation between the ship and the land.

In order to meet the general demands of faults monitoring and diagnosis of electric drives, and by taking the safety and efficiency into account, a general fault model has been established to handle the faults of electric drives in this paper.

This paper studies the definition of diagnosability and the computation method of diagnosability based on information entropy,analyzes the influence of the transformer fault diagnostic precision to transformer fault diagnosability.

This paper researched the approaches to fault diagnosis and the problem of fault diagnosability for systems with both the delayed states and delayed measurements.

The approach of fault diagnosis and the problem of fault diagnosability are researched for linear systems with state delays.

This paper describes the merit and necessity of developing reusable intelligent fault-diagnosis-system based on WEB, then discusses the feasibility of reusing some kinksof intelligent engines, and analyses how to use the Java agent architecture and java xmlfunction in this system.
