In this paper, an optimal PID controller is introduced for an antagonistic variable stiffness actuator (AVSA) based on Hammerstein models.A set of Hammerstein models is developed for the AVSA using the voltage difference method.For each stiffness level, linear and nonlinear Hammerstein models are identified using the least squares method.Experiment
The heterogeneous oxidation of olefins to vicinal diols was investigated using an Os-Zn-Al hydrotalcite-like catalyst (HTlc).The Os-Zn-Al HTlc was synthesised by the co-precipitation method and characterised fully using XRD, FT-IR, TEM, SEM, ICP-OES and BET surface area measurements.The ability of the synthesised Os-Zn-Al HTlc to catalytically dihy
Abstract This paper presents the computational-based ballistic limit of laminated metal panels comprised of high strength steel Visor Insert and aluminium alloy Al7075-T6 plate at different thickness combinations to necessitate the weight reduction of existing armour steel plate.The numerical models of monolithic configuration, double-layered confi

Takotsubo syndrome (TTS) is an Digital Portion Scales increasingly recognized condition burdened by significant acute and long-term adverse events.The availability of novel techniques expanded the knowledge on TTS and allowed a more accurate risk-stratification, potentially guiding clinical management.The present review aims to summarize the recent
