The problem of guaranteed cost finite-time control of fractional-order positive switched systems (FOPSS) is considered in this paper.Firstly, a new cost function is defined.Then, by constructing linear copositive Lyapunov functions and using the average dwell time (ADT) approach, a state Intermediate feedback controller and a static output feedback
Abstract The COVID-19 outbreak is asynchronous in US counties.Mitigating the COVID-19 transmission requires not only the state and federal level order of protective measures such as social distancing and testing, but also public awareness of time-dependent risk and reactions at county and community levels.We propose a robust approach to estimate th
BackgroundIn the ICU, patients with acute myocardial infarction and cardiogenic shock (AMI-CS) often face high mortality rates, making timely and precise mortality risk prediction crucial for clinical decision-making.Despite existing models, machine learning algorithms hold the potential for improved predictive accuracy.MethodsIn this study, a pred
Trial series of cast alloy MO59 obtained from qualified scrap was investigated.SEM and TEM of resulting precipitates were conducted.The SEM analysis demonstrated the dependence of silicon, phosphorus, iron, chromium and nickel in the composition of the so-called hard precipitates.TEM analysis showed the formation of phase AlFeSi and AlCr.Made studi
