This paper uses a multiscale statistical framework to estimate groundwater travel times and to derive conditional travel time probability densities. In the applications of interest here travel time uncertainties depend primarily on uncertainties in hydraulic conductivity. These uncertainties can be reduced if the travel times are conditioned on scattered measurements of hydraulic conductivity a...

Reliability of a system is the probability that it will function as intended for the required period of time. The opposite of reliability is failure probability per unit time or over time, such as a life cycle. Following a review of existing reliability codes and approaches, comprehensive approaches to assess the reliability of offshore structures are described, including probabilistic analysis...

Transportation is an essential driver of the supply chain; directly impacts both the responsiveness and efficiency therein. The decision of route selection based on the optimal travel time reduces the product delivery time and cost; enhancing customer satisfaction. This paper presents a case study identifying the optimal routes in a network consisting of 81 alternatives. Various sample data wer...

Animal locations are sometimes estimated with hyperbolic techniques by estimating the difference in distances of their sounds between pairs of receivers. Each pair specifies the animal's location to a hyperboloid because the speed of sound is assumed to be spatially homogeneous. Sufficient numbers of intersecting hyperboloids specify the location. A nonlinear method is developed for computing p...

Numerical simulation of plasma turbulence in the Large Plasma Device LAPD W. Gekelman, H. Pfister, Z. Lucky et al., Rev. Sci. Instrum. 62, 2875 1991 is presented.
