RISApplication of Discrete-Event Simulation in the Quantitative Evaluation of Information Systems in Infrastructure Maintenance Management Processes
Publisher: American Society of Civil Engineers
Abstract: Information technology (IT) has increasingly been highlighted in the construction industry as an integral contributor in improving project performance and competition. IT application challenges for infrastructure operation ...
Unsteady Natural Convection Heat Transfer Past a Vertical Flat Plate Embedded in a Porous Medium Saturated With Fractional Oldroyd-B Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates natural convection heat transfer of generalized Oldroyd-B fluid in a porous medium with modified fractional Darcy's law. Nonlinear coupled boundary layer governing equations are formulated with ...
Life-Cycle Assessment of Concrete Dam Construction: Comparison of Environmental Impact of Rock-Filled and Conventional Concrete
Publisher: American Society of Civil Engineers
Abstract: Massive concrete dam projects will be constructed in the next 10 years to respond to the increasing demand for clean energy and water resources in developing countries. Because of their ample use of cement, these projects ...
Seawater/Seawater Cascade-Scrubbing Desulfurization Performance for Exhaust Gas of a 162-kW Marine Diesel Engine
Publisher: ASCE
Abstract: To confirm the higher-availability and lower-resistance superiority of a proposed seawater/seawater cascade-scrubbing solution meeting the emission control area (ECA) requirements under harsh high-sulfur and low-alkalinity ...
Influence of Accessibility to Urban Service Amenities on Housing Prices: Evidence from Beijing
Publisher: ASCE
Abstract: Housing prices are deeply influenced by urban service amenities, and measuring this effect is necessary to help administrations construct informed urban planning strategies. However, studies have not fully assessed the ...
Analysis of Shroud Cavity Leakage in a Radial Turbine for Optimal Operation in Compressed Air Energy Storage System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important energy generation device of the compressed air energy storage (CAES) system, the radial-inflow turbine with shrouded impeller is employed to avoid the leakage flow in the rotor, especially in the high-pressure ...
A Study on Adapted Similitude Modeling Method of Turboexpander With Different Gas Working Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study on similitude modeling method of turboexpander with different working fluids is not only the key technical means and necessary method for the research and development of turboexpander with special working fluids ...
Tribological Behavior of Diamondlike Carbon Film-Deposited Ti6Al4V Alloy Swinging Against Ultrahigh Molecular Weight Polyethylene in Fetal Bovine Serum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Titanium alloys are widely used in the field of artificial joints, but their poor wear resistance limits their clinical application. Therefore, in this paper, the diamondlike carbon (DLC) film deposited on Ti6Al4V alloy ...
Experimental and Numerical Investigations of Closed Radial Inflow Turbine With Labyrinth Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is a common practice to use closed impeller in radial inflow turbine against the flow leakage from tip clearance of impellers, especially in small volume flow condition. It utilizes labyrinths between the shroud and the ...
Setting Time Optimization of Excessive-Sulfate Phosphogypsum Slag Cement for Self-Compacting Concrete Based on a Paste Rheological Threshold Theory
Publisher: American Society of Civil Engineers
Abstract: The accumulation of phosphogypsum (PG) has become a significant environmental and economic challenge, making PG reuse an urgent concern. This study aims to explore the potential of combining PG with steel slag (SS), ground ...
