RISNumerical Analysis of Transient Wheel-Rail Rolling/Slipping Contact Behaviors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wheel slips often produce wheel/rail damage, threatening the operation safety, and increasing the maintenance cost of contact-type railways. To understand the characteristics of wheel slips for further development of more ...
Ovalization Restraint in Four-Point Bending Tests of Tubes
Publisher: American Society of Civil Engineers
Abstract: Four-point bending tests have been a staple in many structural engineering experiments as a reliable way of assessing the bending resistance of circular hollow sections, tubes, and cylindrical shells, and they continue to ...
Construction Workers’ Representativeness Heuristic in Decision Making: The Impact of Demographic Factors
Publisher: ASCE
Abstract: A representativeness heuristic (RH) refers to a shortcut in decision making, one or two subdimensions of which have been found to impact construction workers’ unsafe behaviors prominently. To reduce workers’ reliance on ...
Principal Factor Analysis for Forecasting Diurnal Water-Demand Pattern Using Combined Rough-Set and Fuzzy-Clustering Technique
Publisher: American Society of Civil Engineers
Abstract: The true principal factors for the diurnal water-demand pattern of urban water are often difficult to identify using traditional rough-set algorithms because the demand pattern is usually affected by many factors that are ...
Modified Damage Model of Aeolian Sand Self-Compacting Concrete
Publisher: American Society of Civil Engineers
Abstract: Modeling of concrete damage is an important branch of concrete structural analysis; however, the damage behavior of different types of concrete varies. In this study, mechanical property tests were conducted to modify the ...
Influence of Metakaolin on Properties of Magnesium Potassium Phosphate Cement with High Water-to-Solid Ratio
Publisher: ASCE
Abstract: In this paper, the effect of metakaolin on the performance of magnesium potassium phosphate cement (MKPC) with a high water-to-solid (w/s) ratio of 0.375 was studied. MKPC was prepared by substituting metakaolin for varying ...
Control-Oriented Nonlinear Modeling and Temperature Control for Solid Oxide Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a variable structure controller for temperature control of the solid oxide fuel cell (SOFC) is proposed. The performance and availability of the SOFC are greatly dependent on ...
Psychological Driving Mechanism of Safety Citizenship Behaviors of Construction Workers: Application of the Theory of Planned Behavior and Norm Activation Model
Publisher: ASCE
Abstract: Researchers and practitioners are focusing greater attention on safety citizenship behavior (SCB), an important factor in preventing injuries and improving workplace safety conditions; however, very little research has ...
Fabrication of Support Tubular Proton Exchange Membrane For Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The support tubular proton exchange membranes (STPEMs) were fabricated successfully by impregnating porous silica pipe into a solution of perfluorinated resin. The structures of the inner, outer, ...
Dynamical Seasonal Prediction of Tropical Cyclone Activity Using the FGOALS-f2 Ensemble Prediction System
Publisher: American Meteorological Society
