RISRoller‐Compacted Concrete Pavement: U.S. Air Force Decision Model
Publisher: American Society of Civil Engineers
Abstract: This study investigated the possibility of U.S. Air Force use of roller‐compacted concrete pavement (RCCP). A decision model was developed. To do this, the unique pavement requirements of the U.S. Air Force were identified. ...
A Model of a High Temperature Direct Methanol Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A steadystate, isothermal, onedimensional model of a direct methanol proton exchange membrane fuel cell (PEMFC), with a polybenzimidazole (PBI) membrane, was developed. The electrode kinetics were represented by the ...
Fully-Developed Laminar Flow in Sinusoidal Grooves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow of a constant property fluid through a sinusoidal groove has been analyzed. A numerical solution of the conservation of mass and momentum equations for fully developed flow is presented. ...
Head Ejection during Barrier Impacts
Publisher: American Society of Civil Engineers
Abstract: During oblique vehicular impacts with longitudinal barriers, an occupant’s head is often ejected out of a side window. When this occurs, the occupant’s head can contact the barrier or an object attached thereto. This impact ...
Direct Assimilation of AMSR-E Brightness Temperatures for Estimating Sea Ice Concentration
Publisher: American Meteorological Society
Abstract: n this paper a method to directly assimilate brightness temperatures from the Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) to produce ice concentration analyses within a three-dimensional ...
Assimilation of Argo Temperature and Salinity Profiles Using a Bias-Aware EnOI Scheme for the Labrador Sea
Publisher: American Meteorological Society
Abstract: AbstractIn this study, temperature and salinity profiles from Argo floats are assimilated into a coupled ice?ocean model over the North Atlantic Ocean and Arctic using an ensemble optimal interpolation (EnOI) scheme, with ...
Combustion Performance of Biodiesel and Diesel-Vegetable Oil Blends in a Simulated Gas Turbine Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent increases in fuel costs, concerns for global warming, and limited supplies of fossil fuels have prompted wide spread research on renewable liquid biofuels produced domestically from ...
Combustion Performance of Liquid Biofuels in a Swirl-Stabilized Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fuels produced from renewable sources offer an economically viable pathway to curtail emissions of greenhouse gases. Two such liquid fuels in common usage are biodiesel and ethanol derived from ...
Collecting Empirically Derived SAR Characteristic Values over One Year of Sea Ice Environments for Use in Data Assimilation
Publisher: American Meteorological Society
Abstract: new tool has been developed to calculate dynamic, state-specific tie points, to aid in the assimilation of various types of satellite data into Environment and Climate Change Canada?s Regional Ice Ocean Prediction System. ...
Policy Options for Hazardous-Building-Component Removal before Demolition
Publisher: American Society of Civil Engineers
Abstract: A small fraction of the solid waste generated during the demolition of buildings contains chemicals hazardous to human health and the environment. Examples include mercury-bearing fluorescent and high-intensity discharge ...
