RISOne-Dimensional Compression Fractal Theory and Experimental Verification of Coarse-Grained Soil
Publisher: American Society of Civil Engineers
Abstract: Coarse-grained soil particles are suspectible to breakage under high-stress conditions, with particle breakage being the main reason for the compression of samples. The compression coefficient λ in the e–log σ′ curve is ...
Fractal Representation for Effective Stress of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: Bishop’s effective stress equation for unsaturated soils was abandoned for some time because of the difficulties in estimating the value of parameter
1D Free Swelling Model of Bentonite under Chemomechanical Coupling Action
Publisher: ASCE
Abstract: Describing the time-dependent free swelling behavior of bentonite in saline solution is challenging as it is determined by the coupling effect of the chemical field and the swelling stress field in soil. The swelling ...
Fuzzy-Based Adaptive Higher-Order Sliding Mode Control for Uncertain Steer-by-Wire System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes an adaptive higher-order sliding mode (AHOSM) control method based on the adaptive fuzzy logic system for steer-by-wire (SbW) system to achieve the tracking control of the front wheels steering angle. ...
Study on Instability Process of Slag Landfills: Example of the Subgrade Landslide on Fuxin Nanhuan Road in Liaoning, China
Publisher: ASCE
Abstract: The management and knowledge of landfills are generally inadequate and could lead to significant catastrophes. This is particularly concerning for solid waste landfills due to their large size and potential to threaten ...
Saturated Gravity Wave Spectrum in the Polar Summer Lower Thermosphere Observed by Foil Chaff during Campaign “Sodium 88”
Publisher: American Meteorological Society
Abstract: Ten vertical profiles of horizontal winds have been measured at high resolution (25 m) in the range from 85 to 103 km during the sodium campaign in summer 1988 at Andenes, northern Norway (69°N). The purposes of this study ...
Relative Roles of Land–Sea Distribution and Orography in Asian Monsoon Intensity
Publisher: American Meteorological Society
Abstract: The relative impacts of various land?sea distributions (LSDs) and mountains on Asian monsoon extent and intensity are assessed using a series of AGCM simulations. The air?sea coupling effects are not considered in this ...
Synchronous and Asynchronous Integrations in an Ocean General Circulation Model
Publisher: American Meteorological Society
Abstract: A basinwide ocean general circulation model of the North Pacific is used to study the difference in distributions of tracers between asynchronous and synchronous integrations. An integration in which equal time steps and ...
Sensitivity of the Simulated Distributions of Water Masses, CFCs, and Bomb 14C to Parameterizations of Mesoscale Tracer Transports in a Model of the North Pacific
Publisher: American Meteorological Society
Abstract: A basinwide ocean general circulation model of the North Pacific Ocean is used to study the sensitivity of the simulated distributions of water masses, chlorofluorocarbons (CFCs), and bomb carbon-14 isotope (14C) to ...
Numerical Investigation on the Heat Transfer Characteristics of Liquid Lithium Metal in a Bent Tube and Its Structure Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liquid lithium is expected to be the promising coolant for the next generation of space nuclear reactor power sources, and pipe structures have critical impacts on the flow and heat transfer characteristics, whereas related ...
