This paper studies the asymptotic stability of a repairable system with repair time of failed system that follows arbitrary distribution.We show that the system operator generates a positive C0-semigroup of contraction in Wine Glasses a Banach space, therefore there exists a unique, nonnegative, and time-dependant solution.By analyzing the spectrum
The Waikoropupu Springs, Décor:Restaurant Tables a large karst resurgence 4 km from the coast, are supplied by the Arthur Marble Aquifer (AMA) underlying the Takaka Valley, South Island, New Zealand.New evidence on the recharge sources in the catchment, combined with previous results, is used to establish a new recharge model for the AMA.Combined
Rotor-craft style UAV, such as the quadrotor, has become increasingly popular with researchers due to its advantages over fixed-wing UAV.The quadrotor is highly maneuverable, can perform vertical take-off and landing (VTOL), and can hover flight capability.Nevertheless, handling the quadrotor complex, highly nonlinear dynamics is difficult and chal
Fungal urinary tract infections are an increasing problem in hospitalized patients.Funguria may be a result of contamination of the urine specimen, colonization of the urinary tract, or may be indicative of true invasive infection.In this study, we report the risk factors, clinical features, treatments and outcome in a group of 68 hospitalized pati
