in this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for v47/660kw wind turbine operated in manjil wind farm, gilan province, iran. according to the acquired data from iran wind turbine industry, common faults of the wind turbine such as sensor fault...

vehicle driveline system and its working accuracy play an important role in the performance of car. the purpose of this study is to provide an appropriate mechanism for investigating, identifying and determining the position and size of defects in the vehicle power transmission system. this is based on the patterns of the residual signal, obtained from a simulated model of the system. neuro-fuz...

The objective of ESPRIT-project 6731 FTMPS [1] is to develop techniques and system software to integrate Fault Tolerance in Massively Parallel Systems [2] . This covers the whole range from error detection, over fault-diagnosis and fault isolation to system and application recovery. Important is the research for applicability in massively parallel systems as well as the development of system so...

--The Motor Current Signature Analysis (MCSA) is considered the most popular fault detection method now a day because it can easily detect the common machine fault such as turn to turn short ckt, cracked /broken rotor bars, bearing deterioration etc. The present paper discusses the fundamentals of Motor Current Signature Analysis (MCSA) plus condition monitoring of the induction motor using MCS...

In this work we present a formal approach to the design of Fault Detection and Identification (FDI) components. We define a comprehensive language for the specification of FDI, and discuss how to check whether a given FDI component fulfills its specification. Then, we propose an automatic procedure to synthesize an FDI component that satisfies a given specification. The approach has been implem...

We examine multinationals’ optimal entry modes into foreign markets as a function of market size, FDI fixed costs, tariffs and transport costs. Our results highlight why large countries are more likely to attract acquisition investment, while intermediate sized countries may be served predominantly through trade, even in the presence of high tariffs. Small countries are most likely to experienc...

Recent literature on multinational firms has stressed the importance of low productivity as a barrier to the cross-border expansion of firms. However, firms typically also need external finance to finance the costs of market entry. In addition to productivity-related real barriers, financial constraints may thus restrict market entry. Building on a model of multinational firms facing real and f...
