RISActual and Reference Evaporative Losses and Surface Coefficients of a Maize Field during Nongrowing (Dormant) Periods
Publisher: American Society of Civil Engineers
Abstract: Effective water resources planning, allocation, management, and use in agroecosystems require accurate quantification of actual evapotranspiration
Fretting Fatigue—An Integral Simulation Approach to Strengthening by Shot Peening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fretting fatigue is a limiting factor in blade attachment design for turbomachinery. Shot peening is known to be a strength increasing measure against fatigue. It is applied not only to free surfaces of components under ...
Application of TQM to Environmental Construction
Publisher: American Society of Civil Engineers
Abstract: Cost and schedule data were obtained for 40 environmental construction projects built for the United States Navy. Total Quality Management (TQM) techniques were used during the construction of 21 of the projects. The amount ...
Engine Emission Modeling Using a Mixed Physics and Regression Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel control-oriented model of the raw emissions of diesel engines. An extended quasistationary approach is developed where some engine process variables, such as combustion ...
The Dynamical Influence of the Atlantic Multidecadal Oscillation on Continental Climate
Publisher: American Meteorological Society
Abstract: AbstractThe Atlantic multidecadal oscillation (AMO) in sea surface temperature (SST) has been shown to influence the climate of the surrounding continents. However, it is unclear to what extent the observed impact of the ...
End Connection Effects on Vortex Shedding Susceptibility of Welded Aluminum Truss Tubular Web Members
Publisher: American Society of Civil Engineers
Abstract: A series of experiments and analyses have been conducted to assess the vulnerability of hollow circular web members in welded aluminum sign truss structures to wind-induced resonant vibrations. Results from nondestructive ...
Dynamic Measurements of In-Place Steel Floors to Assess Vibration Performance
Publisher: American Society of Civil Engineers
Abstract: The research presented in this paper resolves several measurement issues pertaining to the experimental modal analysis of lightweight steel floor systems. This investigation represents a first step toward collecting more ...
Model-Based Actuator Trajectories Optimization for a Diesel Engine Using a Direct Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a novel optimization method that allows a reduction in the pollutant emission of diesel engines during transient operation. The key idea is to synthesize optimal actuator ...
Numerical Modeling Study of Hydraulic Impact of a Large Sediment Capping Facility
Publisher: American Society of Civil Engineers
Abstract: An engineered containment facility (ECF) that would cap and contain some of the most contaminated sediments in Hamilton Harbour has been proposed. Because of the size and shape of this structure, the ECF will alter local ...
Life-Cycle Assessment Comparison for Long-Span Cable and Truss Structural Systems: Case Study
Publisher: American Society of Civil Engineers
Abstract: The architectural engineer has a considerable influence on the sustainability of buildings. The reduction in environmental impacts of building materials, as measured by life-cycle assessment (LCA), has recently become a ...
