In this investigation, the explicit expressions for reliability function and mean time to failure (MTTF) of a repairable system with provision of spares and removable multi-repair facility have been established. In removable repairmen strategy, the repairmen turn on when there are N or more than N failed units and turn-off when system is empty. The failure times of operating/spare units and rep...

In this paper, based on viscosity technique with perturbation, we introduce a new non-linear viscosity algorithm for finding a element of the set of fixed points of nonexpansivemulti-valued mappings in a Hilbert space. We derive a strong convergence theorem for thisnew algorithm under appropriate assumptions. Moreover, in support of our results, somenumerical examples (u...

This paper presents a law of large numbers result, as the size population tends to infinity, SIR stochastic epidemic models, for distributed over $ L distinct patches (with migrations between them) and K groups (possibly age groups). The limit is set Volterra-type integral equations, result shows effects both spatial heterogeneity. novelty model that infectivity an infected individual infection...

objectives: alzheimer’s disease causes many negative effects on the individual's physical, psychological and cognitive conditions. the multi sensory stimulation helps the patients to improve their physical, psychological and cognitive conditions. the aim of this study is to determine the effect of multi sensory stimulation on cognitive status and quality of life of the patients with alzhei...
