Current estimates show that there are about 40,000 bridges in Australia, of which 27,000 are aging timber bridges. Maintaining existing timber bridges is important to eliminate possibilities of structural collapse which can have catastrophic outcomes to the community. Aging timber bridges have a high maintenance cost. Relating different types of defects to possible underlying causes make deterioration...
This paper describes the evolution of an especially designed sub sea Remotely Operated Vehicle (ROV) with dedicated electromagnetic flux leakage searching arm as a part of associated intelligent Non Destructive Testing arrangement, which is intended for inspecting the outer surface of large ship hull and floating production storage offloading (FPSO) platforms with complex shaped structures. Current...
Structure of dish centrifugal separator is described firstly. According to the characters of the dish centrifugal separator's main faults, a serial of methods of extracting fault feature are figured out. In the process of classifying and recognizing faults, the advantages of expert system and artificial neural network are combined together. The experiment results show that the methods presented here...
Causality diagram theory is a kind of uncertainty reasoning theory based on the belief network. It expresses the knowledge and causality relationship by diagrammatic form and direct causality intensity. Furthermore, it resolves the shortages of the belief network, and realizes a hybrid model which can process discrete and continuous variations. The theory of causality diagram model and the steps of...
It is necessary to guarantee that timely diagnosis of fans of coal fault is for mine safety production in enterprises. To establish fans of coal fault diagnosis expert system is a kind of effective way for improving fans fault diagnosis. The roughness set is applied to fans fault expert system for knowledge; this way can improve the objectivity of mining knowledge, which to establish effectively fans...
The expert system FOETOS is designed to aid diagnosis and prognosis of foetal condition during the nonstress test, foetal biophysical profiling, the contraction stress test, labour and the immediate neonatal period. Its action during labour to generate the following information is described: (1) characteristics, aetiology, diagnosis, prognosis, and therapeutic advice concerning the state of the foetus;...
