In this paper, stability is studied for a class of switched singular systems containing both stable and unstable modes.By introducing a time-varying piecewise Lyapunov function (TVPLF) and a mode-dependent average dwell time (ADT) switching rule, the computable sufficient conditions for system stability are derived.The time-varying piecewise Lyapun

BackgroundAcute kidney injury (AKI) complicates shock.Diagnosis is based on rising creatinine, a late phenomenon.Intrarenal vasoconstriction occurs earlier.Measuring flow resistance in the renal circulation, Renal Resistive Index (RRI), could become part of vital organ function assessment using Doppler ultrasound.Our aim was to determine whether RR
Proportional Integral Derivative (PID) controllers are widely used inmany fields because they are skull bride and groom simple and effective.Tuning of the PIDcontroller parameters is not easy and does not give the optimal requiredresponse, especially with non-liner system.In the last two decades manyintelligent optimization techniques were took att
Although mass vaccination is the best way out of the pandemic, the share of skeptics is substantial in most countries.Social campaigns can emphasize the many arguments that potentially increase acceptance for vaccines: swish supreme glide track white e.g., that they have been developed, tested, and recommended by doctors and scientists; and that th
