Diagnostics play a very important role in the modern Tokamak where optimum performance is essential. To achieve this, the device must be equipped with reliable and robust sensors and instrumentation that allow the operation envelope to be fully explored. Development of these diagnostics to maintain this reliability is necessary. Further to the development, the systems must be integrated in a way that...
A generic framework for estimating the reliability of equipment is through “information fusion” of its failure history, predictive maintenance data and domain expert's knowledge is proposed and demonstrated. The framework uses “Degree of Certainty” arrived at using fuzzy sets and “Belief” & “Plausibility” measures to arrive at a decision on the effectiveness of predictive maintenance. Uncertainty,...
Equipment Health Monitoring through Predictive Maintenance (PDM) data is proposed and the same is demonstrated with case study. Steel Rolling Mill Gearbox is considered for the purpose. Empirical failure rate model using Equipment Health Index (EHI) is proposed and used it for forecasting maintenance requirements of the process equipment. The strength of the proposed approach lies in integrating multiple...
The success of demand management approaches to curbing flight delays is predicated on an accurate and reliable a-priori determination of airport arrival and departure capacity. The assignment of declared capacity, completed more than one year in advance, must consider the inherent variability in the actual throughput capacity for each 15 minute period during the day. For airports with large variations...
New statistical methods allow discovery of causal models from observational data in some circumstances. These models permit both probabilistic and causal inference for models of reasonable size. Many domains can benefit from such methods. Educational research does not easily lend itself to experimental investigation. Research in laboratories is artificial while research in authentic environments is...
Transportable terminals play an important role in modern satellite communication. They can be installed at short notice at any place and communication through satellite can be established. The 3M Air transportable terminal (ATT-3) is a flexible and rapidly deployable satellite ground terminal that has been designed to provide communication with ATT-3.In this paper reliability, availability and maintainability...
This paper assesses the effectiveness and reliability of monitoring techniques for real-time fault detection in bearings of induction motor. The bearing failure modes and the characteristic bearing frequencies associated with the physical construction of the bearings are examined. Experimental results of vibration spectra with different faults are included, for a 7.5 kW cage induction motor, to demonstrate...
