RISElectrostatic Precipitator for Metal and Particulate Emission Control
Publisher: American Society of Civil Engineers
Abstract: Improving air pollution control systems is crucial for incinerators to be an option for sewage sludge disposal. Combinations of venturi and tray tower scrubbers are the most popular air pollution control system for sewage ...
A Dynamic Analysis on the Transition Curve of Profiled Chamber Metering Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A profiled chamber metering pump (PCMP) is a new type of positivedisplacement vane pump which is composed of a special stator and a rotor–slide assembly. The faceshaped curve of the inner chamber of the stator is formed ...
Approximate Simulation of Natural Structured Soft Clays Using a Simplified Bounding Surface Model
Publisher: American Society of Civil Engineers
Abstract: A simple version of a recently proposed anisotropic elastoplastic bounding surface model was used to simulate the mechanical behavior of natural Shanghai soft clay. The characteristics of stress–strain curves attributable ...
Meso-analysis on Skeleton Structure of Coarse-graded Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Meso-structure of skeleton of coarse-graded asphalt mixture was studied numerically in terms of particle coordination numbers and mixture porosity. The results show that coarse aggregates play a double role in the mixture. ...
Numerical Simulation of Reinforcement for Rock Slope with Rock Bolt (Anchor Cable) Frame Beam
Publisher: American Society of Civil Engineers
Abstract: As two new kinds of compound reinforcement facilities, rock bolt frame beam and anchor cable frame beam are widely used for reinforcement of rock slopes in recent years. However, past studies on the two facilities synthetically ...
Seismic Performance of Welded Stainless Steel H-Section Columns under Cyclic Horizontal Loading
Publisher: ASCE
Abstract: This study investigated the seismic performance of welded stainless steel H-section columns. Ten columns were tested under cyclic horizontal load; their seismic performance was analyzed according to their hysteresis curves, ...
Low-Alite Portland Cement in Steam-Curing Condition: Long-Term Compressive Strength and Permeability
Publisher: ASCE
Abstract: Steam curing is a commonly used method to obtain cement products with high early strength. It is popularly employed to produce prefabricated units in factory. However, the long-term performance of steam-cured products is ...
Dynamic Mechanical Behavior at Elevated Temperatures and High Strain Rates of Low Yield Point Steels
Publisher: American Society of Civil Engineers
Abstract: The goal of this study is to investigate the dynamic mechanical properties of low yield (LY) point steels (LY100, LY160, and LY225) under high strain rates and elevated temperatures. The separate Hopkinson pressure bar ...
Autogenerating/Drawing Valid Arrays and Contracted Graphs With Pentagonal Links for Type Synthesis of Mechanism by Computer Aided Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for autogeneration/draw of valid arrays and contracted graphs by cad is studied in this paper. First, the concepts and relative new criteria of arrays and contracted graphs (CGs) are explained for the representa ...
Impact of Soil Moisture Data Resolution on Soil Moisture and Surface Heat Flux Estimates through Data Assimilation: A Case Study in the Southern Great Plains
Publisher: American Meteorological Society
Abstract: AbstractThe spatial heterogeneity and temporal variation of soil moisture and surface heat fluxes are key to many geophysical and environmental studies. It has been demonstrated that they can be mapped by assimilating soil ...
