TL;DR: In this article, wavelet transform tools are considered as they are superior to both the fast and short-time Fourier transforms in effectively analyzing non-stationary signals, which could result either from fast operational conditions, such as the fast start-up of an electrical motor, or from the presence of a fault causing a discontinuity in the vibration signal being monitored.

TL;DR: A novel modification to the standard particle swarm optimization (PSO) technique is presented and the superiority of the proposed modified technique over other PSO-based techniques is illustrated, with an application to the important area of adaptive channel equalization.

TL;DR: In this article, an internal model principle-based Kalman filter (IMP-KF) structure was proposed for use in the detection of parametric faults, and the proposed scheme was successfully evaluated on both simulated and physical systems.

TL;DR: The unified fault detection and isolation method is successfully evaluated on both simulated data as well as on real data obtained from a benchmarked laboratory-scale coupled-tank system used to exemplify an industrial two-tank process.

TL;DR: This paper presents an approach for detecting, locating and estimating the size of leak in a pipeline using pressure sensors, differential pressure sensors and flow-rate sensors that detect small change in pressure to overcome the problem with existing approaches.
