Lunar spiral mining, extending outward from a periodically mobile central power and processing station represents an alternative for comparison with more traditional mining schemes. In...
Application of a Boundary Fitted Coordinate Mass Transport Model
A three-dimensional, boundary fitted coordinate, finite difference, mass transport model was applied to the Providence River in Upper Narragansett Bay, Rhode Island. The governing advection-diffusion...
Sensitivity of Flow and Salt Transport to Uncertainties at Open Boundaries: A 3-D Experience
Understanding the transport due to tidal and sub-tidal exchange processes enables many environmental issues in estuarine systems to be addressed. To achieve this goal, a reliable numerical...
Stochastic Finite & Boundary Element Simulations
Stochastic constitutive properties are important in real-world design-analyses. Therein the spatially varying random coefficients in field equations necessitate rather unconventional computational...
A Stochastic Approach to the Fatigue Reliability
