A unified scheme to solving arbitrary complex-valued ratio distribution with application to statistical inference for raw frequency response functions and transmissibility functions (2020)
Journal Article

© 2020 Elsevier Ltd Complex-valued ratio distributions arises in many real applications such as statistical inference for frequency response functions (FRFs) and transmissibility functions (TFs) in structural health monitoring. As a sequel to our pre...

Optimal sensor and actuator placement for structural health monitoring via an efficient convex cost-benefit optimization (2020)
Journal Article

© 2020 Elsevier Ltd The number and position of sensors and actuators are key decision variables that dictate the performance of any structural health monitoring system. This paper proposes choosing them optimally by using an objective function that c...

Generation of graded porous structures by control of process parameters in the selective laser melting of a fixed ratio salt-metal feedstock (2020)
Journal Article

The demonstration of salt dissolution incorporated within laser powder-bed fusion fabrication processes has allowed the creation of complex porous structures without the need for sophisticated design algorithms. This serves to simplify the process, f...

Reuse of a Damaged Permanent Magnet Synchronous Motor for Torque Ripple and Acoustic Noise Elimination using a Novel Repetitive Observer (2020)
Journal Article

A lad-used servo permanent magnet synchronous motor (PMSM) has been accidentally damaged due to overcurrent. On one hand, the mechanical damage in the end bearing and break part generates acoustic noise even when rotating the shaft by hand. On the ot...

Transient ultrasonic guided wave simulation in layered composite structures using a hybrid wave and finite element scheme (2020)
Journal Article

A guided wave simulation method for layered composites based on the wave and finite element scheme is presented. An approach for calculating complex displacement fields such as those generated from piezoelectric transducers is developed. The scatteri...

Volumetric error modelling of a stereo vision system for error correction in photogrammetric three-dimensional coordinate metrology (2020)
Journal Article

Optical three-dimensional coordinate measurement using stereo vision has systematic errors that affect measurement quality. This paper presents a scheme for measuring, modelling and correcting these errors. The position and orientation of a linear st...
