System lifespan modeling becomes more complicated when an external event causes the succession of failure in 2 or more system components. Models that don’t consider this common cause failure cause the wrong estimation of system reliability. Let us assume that there are data composed of numbers of successive failures in i, i = 1, ... , n out of n components of system. Data having these character...

The one-dimensional version of the higher order total variation-based model for image restoration proposed by Chan, Marquina, and Mulet in [4] is analyzed. A suitable functional framework in which the minimization problem is well posed is being proposed and it is proved analytically that the higher order regularizing term prevents the occurrence of the staircase effect.

There is currently a large regional effort to restore tidal marsh ecosystems in the San Francisco BayDelta Estuary involving the commitment of hundreds of millions of dollars and broad landscape-scale habitat manipulations. Although climate change has been on the horizon for many years, recent developments suggest that it must be taken seriously as a factor to be considered in future planning f...

Purpose Healthcare providers (HCP) who care for traumatically injured service members are at risk for stress, burnout, and decreased clinical effectiveness. After two decades of war, the intensive work environment and stress associated with caring for these service members and their families are damaging the emotional and physical wellbeing of our military HCPs. This pilot study explored the ef...

Floodplain restoration projects are part of sustainable flood management model. However, in practice, they are rarely implemented. We analyze the failure of a floodplain restoration project that was supposed to be implemented on the River Rhône (France). Based on the analysis of floodplain restoration projects implementation literature, we identified several constraints on the implementation of...

In this study, the deformation and damage mechanisms on meso and macro scales in a particulate composite and a polyurethane material, Solithane 113, were investigated. The particulate composite contains 87% by weight of hard particles embedded in a rubbery matrix. Experimental data were analyzed and the effect of material’s microstructure on the deformation and failure mechanisms are discussed.
