Development of Condition Monitoring System for Railway Crossings: Condition Assessment and Degradation Detection for Guided Maintenance

Railway crossings are essential components of the railway track system that allow trains to switch from one track to another. Due to the complex wheel-rail interaction in the crossing panel, crossings are vulnerable elements of railway infrastructure and usually have short service lives. The crossing damage not only results in substantial...

Adaptive prognostics for remaining useful life of composite structures

Prognostics is an emerging field of research that enables the real-time health assessment of an engineering system and the prediction of its future state based on up-to-date information. This field integrates various scientific disciplines including physics/mechanics, computational statistics and probabilistic modeling, machine learning and...

Risk Based Maintenance in Electricity Network Organisations

Presently, maintenance management of assets in infrastructure utilities such as electricity, gas and water are widely undergoing changes towards new working environments. These are mainly driven against the background of stringent regulatory regimes, an ageing asset base, increased customer demands and constrained financial resources. Therefore,...

Condition monitoring for marine refrigeration plants based on process models

Over the last decades the reliability, availability and safety of ships has become increasingly important. The cost and safety risks of ships have increased with the size, and the complexity has led to extensive automation. Many parameters, variables and alarms are available simultaneously for evaluation, but the small crew has many tasks they...
