Nonlinear fault responses are common in industrial systems yet cannot be effectively
extracted by traditional feature extraction methods. In recent years, more techniques based …

1.1 Background With the advanced technological developments, a large amount of complex
and expensive machinery is operated in today's world and it is also expected to meet very …

Nowadays, thin-walled tube bending (D/t≥ 20, D-tube diameter and t-tube thickness) in the
critical bend ratio (R/D≤ 2, R bend radius) is a widely used manufacturing process in the …

Fault detection of ball bearings by the complex and non-stationary vibration signals with
noise is very difficult, especially in the early stages. Also, many failure mechanisms and …

The failure in rolling element bearings as an important part of rotary machine can lead to
machine breakdown. Finding a good strategy for fault diagnosis can help to reduce …

This research work could not have been realized without the support of many people. At the
outset, I am very much indebted to Government of India and Department of Atomic Energy …

In the present study, two commercial greases with different rheological properties were
subjected to four-ball tests to identify their performance in anti-wear and anti-scuffing. A wear …

The aim of structural health monitoring of civil structure is the early detection of damage to
prevent structure failure. But modelling the behaviour of such structure is a very challenging …

In this study, the relationship between system complexity and the system failure is tried to be
established with a series of condition monitoring experiments. On small diameter (1 mm ø) …
