RISSimultaneously Solving Process Selection, Machining Parameter Optimization, and Tolerance Design Problems: A Bi-Criterion Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports an integrated approach for jointly solving the process selection, machining parameter selection, and tolerance design problems to avoid inconsistent and infeasible decisions. The ...
Efficient Geotechnical Reliability Analysis Using Weighted Uniform Simulation Method Involving Correlated Nonnormal Random Variables
Publisher: ASCE
Abstract: In the context of probabilistic analysis involving uncertain factors, efficient reliability methods play an important role for promoting a wider application in engineering practice. Although the ordinary Monte Carlo ...
Micromechanical Investigation of Particle-Size Effect of Granular Materials in Biaxial Test with the Role of Particle Breakage
Publisher: ASCE
Abstract: Understanding the effect of particle size on the shear strength of granular materials is important for geotechnical design and construction. However, previous studies show contradicting results on the relationship between ...
Smoothed Particle Hydrodynamics with Unsteady Friction Model for Water Hammer Pipe Flow
Publisher: ASCE
Abstract: Water hammer flows are almost simulated by using the Eulerian mesh methods including the most popular method of characteristics (MOC). In this paper, smoothed particle hydrodynamics (SPH) of the Lagrangian meshless method ...
Ignition-Characteristic Research of the Diesel Fuel in Combustion Vessel Simulated Diesel Engine Cold Start Condition
Publisher: American Society of Civil Engineers
Abstract: The initial ignition characteristic of fuel spray in a diesel engine is of great significance in the cold start problem. In this paper, the constant volume combustion vessel was applied to simulate the practical diesel ...
Oxidation of Antibiotic Agent Trimethoprim by Chlorine Dioxide: Reaction Kinetics and Pathways
Publisher: American Society of Civil Engineers
Abstract: Trimethoprim (TMP) is a widely prescribed antibiotic frequently detected in the aquatic environment. This study investigates the reactions of TMP and two sub structure model compounds [2, 4-diamino-5-methylpyrimidine (DAMP) ...
Phenomenon of White Mist in Pipelines Rapidly Filling with Water with Entrapped Air Pockets
Publisher: American Society of Civil Engineers
Abstract: The phenomenon of white mist in a rapidly filling pipeline containing an entrapped air pocket is numerically and experimentally investigated. The air-water flow patterns, pressure, and temperature histories are synchronously ...
Primitive Form Godunov-Type Scheme for Two-Phase Homogeneous Water Hammer Flows
Publisher: ASCE
Abstract: The primitive form second-order Godunov-type scheme is developed to simulate two-phase homogeneous water hammer flows. Compared with the previous solution schemes applied to homogeneous flows, the proposed model introduces ...
Active Control of Stay Cable Vibration Using a Giant Magnetostrictive Actuator
Publisher: American Society of Civil Engineers
Abstract: Although giant magnetostrictive actuators (GMAs) have been widely studied in the field of active vibration control, the effectiveness of GMAs to control the vibration of cable structures has not been reported yet. This ...
Hydrometeorological Processes and Moisture Sources in the Northeastern Tibetan Plateau: Insights from a 7-Yr Study on Precipitation Isotopes
Publisher: American Meteorological Society
Abstract: The northeastern Tibetan Plateau is located in a climatic junction, which is considered an ideal region to explore the interactions between the summer monsoons and the westerly circulation patterns. However, to date, the ...
