Since actual carbon usage is much greater than predicted at the Granular Activated Carbon (GAC) plant in Mililani, operational costs are higher than estimated. Therefore, diffused aeration and mechanical mixing were examined ...

Concern surrounding recent evidence of over-pumping in the Iao aquifer on Maui has prompted an investigation into the long-term sustainability of current and future withdrawal scenarios. As part of this investigation, a ...

A computer program, ImagePAC 2000, was designed to calculate the asphalt content, percent air voids, percent elongation, and aggregate gradation from a crosssectional image of a gyratory compacted hot mix asphalt pavement ...

The Resistance Value (R-value) is commonly used by the Hawaii Department of Transportation engineers to design the thickness of flexible pavements. Direct measurements of the R-value require equipment that is not readily ...

A theoretical non-hydrostatic model is developed to describe the dynamics of a two-layer shallow water system in the presence of viscous and Coriolis effects. The Navier-Stokes equations are integrated over the water depth ...

1.2 Objective This study investigated the effects of sulfate exposure on the mechanical properties of Portland cement concrete. Concrete specimens cast from mixtures composed of locally available aggregate and cement were ...
