This paper is designed to deal with the convergence and stability analysis of impulsive Caputo fractional order difference systems. Using the Lyapunov functions, the Z-transforms of Caputo difference operators, and the properties of discrete Mittag-Leffler functions, some effective criteria are derived to guarantee the global convergence and the exponential stability of the addressed systems.
Assessing the risks of steering system faults in underwater vehicles is a human-machine-environment (HME) systematic safety field that studies faults in the steering system itself, the driver’s human reliability (HR) and various environmental conditions. This paper proposed a fault risk assessment method for an underwater vehicle steering system based on virtual prototyping and Monte Carlo simulation...
A novel flow injection chemiluminescence (CL) system for determination of polyhydroxy phenols, including phloroglucinol, pyrogallol, resorcinol and pyrocatechol has been described. The system utilises CL reaction of ferricyanide with polyhydroxy phenols in sodium hydroxide media sensitised by the fluorescent dye Rhodamine B. The proposed procedure has a linear range of 0.05-5.0 ng ml/' for phloroglucinol,...
