Lower Confidence Bounds For System Reliability From Binary Failure Data Using Bootstrapping, Lawrence Leemis
Lower Confidence Bounds For System Reliability From Binary Failure Data Using Bootstrapping, Lawrence Leemis
Arts & Sciences Book Chapters
We consider the problem of determining a (1 – A) 100% lower confidence bound on the system reliability for a coherent system of k components using the failure data (yi, ni), where yi is the number of components of type i that pass the test and ni is the number of components of type i on test, i1, 2, …, k. We assume throughout that the components fail independently, e.g. no common-cause failures. The outline of the article is as follows. We begin with the case of a single (k1) component system where n components are placed on a test …
A Population Density Model Of The Driven Lgn/Pgn, Marco A. Huertas, Gregory D. Smith
A Population Density Model Of The Driven Lgn/Pgn, Marco A. Huertas, Gregory D. Smith
Arts & Sciences Book Chapters
The interaction of two populations of integrate-and-fire-or-burst neurons representing thalamocortical cells from the dorsal lateral geniculate nucleus (dLGN) and thalamic reticular cells from the perigeniculate nucleus (PGN) is studied using a population density approach. A two-dimensional probability density function that evolves according to a time-dependent advection-reaction equation gives the distribution of cells in each population over the membrane potential and de-inactivation level of a low-threshold calcium current. In the absence of retinal drive, the population density network model exhibits rhythmic bursting. In the presence of constant retinal input, the aroused LGN/PGN population density model displays a wide range of responses …
