Monitoring is at the heart of cluster management. Instrumentation data is used to schedule tasks, load-balance devices and services, notify administrators of hardware and software failures, and generally monitor the health and usage of a system. The information used to perform these operations must be gathered from the cluster without impacting performance.(More)
Due to recent advances in polymers, photovoltaics, and batteries a unique type of aircraft may be feasible. This is a "solid-state" aircraft, with no conventional mechanical moving parts. Airfoil, propulsion, energy production, energy storage and control are combined in an integrated structure. The key material of this concept is an ionic polymeric-metal(More)

Uncertainty is an important part of formal decision making. Acknowledging this point, modern probabilistic risk assessments (PRAs) typically include uncertainty on parameters of the logic models used in the assessment. What is not addressed in many PRAs is the incorporation of uncertainty specific to the logic models themselves. Our paper investigates the(More)
Dynamic probabilistic risk assessment (DPRA) methodologies couple system simulator codes failures, parameter uncertainties) elements into the simulation. Typically, a DPRA is performed by 1) sampling values of a set of parameters from the uncertainty space of interest (using the simulation controller codes), and 2) simulating the system behavior for that(More)
