Output feedback robust stabilization of distributed‐order systems
Asian Journal of Control, EarlyView.Abstract This paper addresses the challenge of robust fast stabilization for a class of dynamical systems characterized by slow and ultra‐slow dynamics. The system model is approximated using a distributed‐order derivative of the measured output, which captures the influence of the control input, system dynamics, and external disturbances.

Misalignment and Rub-Impact Coupling Dynamics of Power Turbine Rotor with Offset Disk
Applied SciencesWhen the dual rotor system of the aircraft engine is operating, the mass eccentricity of the power turbine rotor and the misalignment of the shaft coupling or the bearing will cause too large vibration of the rotor; this vibration leads to the rub-impact

Full‐order observer design for quadratic port‐controlled Hamiltonian systems
Asian Journal of Control, EarlyView.Abstract The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...

Mathematical Methods in the Applied Sciences, EarlyView., 2022 This article focuses on the fully distributed leader‐following consensus problem of nonlinear fractional multi‐agent systems via event‐triggered control technique. The main intention of this article is to design a novel event‐triggered mechanism, which not only takes into account both the relative error and the absolute error of the samples but also ...

Additively Manufactured Binder‐Free Electrodes for Supercapacitors
Batteries &Supercaps, EarlyView.The study presents an innovative manufacturing process for electrodes in supercapacitors. The masked stereolithography method is used to produce electrodes that do not require a binder or metal foil. The printed electrodes have a microporous charter. Electrochemical measurements show that the additively manufactured electrodes behave in the same way as

Listening to Hong Kong children's perspectives through pretend play
British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

British Educational Research Journal, EarlyView.Abstract This paper explores the critical role that safe spaces, or ‘Pride Groups’, can play in developing ontological security and allyship within schools. Drawing on data collected from eight UK secondary schools and one college, the research evaluates the impact of these groups, using an innovative theoretical framework combining Meyer's minority ...
