Sea surface reservoir ages must be known to establish a common chronological framework for marine, continental, and cryospheric paleoproxies, and are crucial for understanding ocean-continent climatic relationships and the paleoventilation of the ocean. Radiocarbon dates of planktonic foraminifera and tephra contemporaneously deposited over Mediterranean(More)
This paper provides an optimization model based on Real Options (RO) and stochastic dynamic programming for the availability maximization of an offshore wind farm with prognostic capabilities. Alternative energy sources such as offshore wind turbines are promising technologies, but they are capital intensive projects, and the economics of the project depend(More)
Friction stir welding (FSW) is considered one of the most significant developments in joining technology over the last half century. Its industrial applications are growing steadily and so are the number of workers using this technology. To date, there are no reports on airborne exposures during FSW. The objective of this study was to investigate possible(More)
This work proposes a new economic approach that can form a cost-benefit-risk basis for optimum decision making for systems with prognostic capabilities, and a method to assess the value of PHM for its user after a prognostic indication. PHM potentially enables performance based logistics, condition-based maintenance, and reduced life cycle cost. When an(More)
Prognostics and Health Management (PHM) enabled maintenance is considered to be the most recent phase in the evolution of maintenance paradigms. It enables outcome-based contracts, dynamic warranties, maintenance-optimized availability, among other benefits. PHM enables flexibility whereby the decisionmaker can choose from a set of options arising after(More)
A description is given of the design and construction of the Adelaide 6.65-m VUV monochromator. The instrument has an off-plane Eagle mounting and can be used in the first order over a wavelength range from central image to 460 nm. Digital encoders are used to monitor the angular rotation and linear displacement of the grating to provide servocontrolled(More)
