In this paper. we study the finite-time stability and applications of positive switched linear delayed systems under synchronous impulse control. which includes two types of random switching and average dwell time switching. By constructing a type of linear time-varying co-positive Lyapunov functional. https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC550-WUH721816ALE6L0-0F38460-16TB-7-2K-RPM-SATA-6Gb-s-512e-ISE-3-5in-Hard-Drive/
