RISEffect of Dy3+ on the Microstructure and Electrical Properties of Ce0.8 Sm0.2−x Dyx O1.9 (0 ≤ x ≤ 0.15) Electrolytes for IT-SOFC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-quality nanosized Ce0.8 Sm0.2-x Dyx O1.9 (0 ≤ x ≤ 0.15) powders were successfully synthesized by solution combustion method. Calcined Ce0.8 Sm0.2−x Dyx O1.9 (0 ≤ x ≤ 0.15) powders and ...
Modeling of Pollutant Dispersion in Stratified Oscillatory Flows
Publisher: American Society of Civil Engineers
Abstract: A model is presented for predicting the rate of longitudinal dispersion in nonhomogeneous oscillatory flows. The model consists of mathematical representations of velocity and salinity over a cross section and their ...
Three-Dimensional Frictional Contact Analysis Using the Homotopy Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional contact problem with the orthotropic Coulomb friction is formulated in the form of a system of nonlinear equations. The nonlinear complementarity formulation derived naturally ...
A Study on the Knocking and Misfire Detection System Using Breakdown Voltage Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engine knocking and misfire cause a negative effect on the engine power and the exhaust emissions such as HC, CO and NOx. They also cause permanent damages to the three way catalyst (TWC) ...
Volatile Organic Compound (VOC) Transport through Compacted Clay
Publisher: American Society of Civil Engineers
Abstract: Movement of volatile organic compounds (VOCs) through compacted clay liners was investigated using laboratory-scale column and tank tests. Hydraulic conductivity of the compacted clay was not significantly impacted by the ...
Cash Flow Forecasting Model for General Contractors Using Moving Weights of Cost Categories
Publisher: American Society of Civil Engineers
Abstract: This research introduces the development of a project-level cash flow forecasting model from a general contractor’s viewpoint. While most previous models have been proposed to assist contractors in forecasting cash flow ...
Effective Porosity and Seepage Velocity in Column Tests on Compacted Clay
Publisher: American Society of Civil Engineers
Abstract: A series of column and tank tests were conducted using bromide to estimate seepage velocity through compacted clays. Bromide concentrations in effluent and sectioned-core pore water were measured. The seepage velocity ...
Effectiveness of Scrap Tire Chips as Sorptive Drainage Material
Publisher: American Society of Civil Engineers
Abstract: Scrap tire disposal is a problem of growing concern. One solution to this problem is innovative methods for the reuse and recycling of scrap tires. Based on batch isotherm tests, scrap tire chips have been identified to ...
Sediment Flushing at the Nakdong River Estuary Barrage
Publisher: American Society of Civil Engineers
Abstract: The Nakdong River Estuary Barrage (NREB) prevents salt-water intrusion but causes sedimentation problems in the Lower Nakdong River in South Korea. Its mitigation requires mechanical dredging to maintain the flood conveyance ...
Interference Assemblies
Publisher: American Society of Civil Engineers
Abstract: This paper contains the development of a method for determining the contact pressure distribution along the mating surfaces of two members assembled together with an initial interference fit. This method utilizes superposition, ...
