Equipment failures lead to unexpected downtimes that often result in a significant capital and productivity loss. A condition monitoring system (CMS) is critical in alleviating such equipment downtime and to ensure reliability ...

Condition Monitoring (CM) is an important approach to extending the life of complex equipment by forecasting the outcome of an event before catastrophic failure occurs. Recent advancements in digital twins (DT) offer ...

Vibration signals collected from gearboxes in an industrial environment are characterized by inherent machine speed fluctuation and complex multicomponents, which make it difficult to extract reliable fault information. ...

This paper provides an overview of the recent advances made in the field of fault diagnosis of industrial machines operating under variable speed conditions. First, the shortcomings of the traditional techniques in extracting ...

Order tracking (OT) of vibration envelope signal based on instantaneous frequency (IF) estimated from a time-frequency representation (TFR) is generally applied to detect bearing defects under time-varying speed conditions. ...

The choice of heat transfer fluids (HTFs) significantly dictates the thermal efficiency of the solar power plant. Presently, molten salt is widely used choice owing to its phase, low cost, and non-toxic nature. Along with ...

This research aims to comprehensively analyse the Agri-food supply chain, by identifying the barriers, and considering effective pathways towards a green supply chain. To the best of our knowledge, in the research area of ...

Products make substantial impact on environment. Product to waste mass generated through out the product lifecycle can be as high as 1:20. Design for Environment (DfE) is an approach to design where all the environmental ...

Individual guidelines often exist for DfE but these are not integrated with design tools. There is no comprehensive method that can be useful for the whole life cycle of a product in various stages of its design. Few tools ...

In each stage of product development, we need to take decisions, by evaluating multiple product alternatives based on multiple criteria. Classical evaluation methods like weighted objectives method assumes certainty about ...
