Abstract Selective manipulation of energy levels plays an essential role in realizing multichannel wave devices. One the representative examples is to utilize concept quasi-isospectrality: a family systems with almost identical spectrum except for part levels. Most approaches toward quasi-isospectrality have employed analytical methods based on symmetry or tridiagonalization, such as supersymme...

Failures in high value, safety-critical, inaccessible, and productivity-critical systems is an area of significant research interest. Despite advances predictive continuous maintenance services, there still a need for more ambitious approach to preserve system’s functions despite degradation damage. This paper presents the concept self-engineering (SE) system which utilises techniques such as s...
