Model and Algorithm for Vessel Scheduling through a One-Way Tidal Channel
Publisher: ASCE
Abstract: Efficient vessel scheduling through a channel can improve the operational efficiency of ports. Additionally, many large vessels with a deep draft have delays related to tidal cycles when passing through tidal channels. ...
Analysis of Dynamic Behavior for Slab Track of High-Speed Railway Based on Vehicle and Track Elements
Publisher: American Society of Civil Engineers
Abstract: Slab tracks are used worldwide in high-speed railways. The slab may be cast in situ, resulting in a continuous length of concrete, or it may be constructed in discrete precast sections laid end to end. According to structural ...
Landscape Character Diversity and Zoning Management: Case of Wuhan Metropolitan Area
Publisher: ASCE
Abstract: The landscape character of metropolitan areas faces the problem of competition between protection and development. This study explores the synergism of management, protection, and development of landscape character diversity ...
Experimental Studies and Constitutive Modeling of Static Liquefaction Instability in Sand–Clay Mixtures
Publisher: ASCE
Abstract: This paper examines static liquefaction phenomena in sand–clay mixtures from both experimental and theoretical perspectives. Consolidated undrained triaxial tests (CU tests) are implemented on a mixture of sand and clay ...
Comparison of ANNs and Empirical Approaches for Predicting Watershed Runoff
Publisher: American Society of Civil Engineers
Abstract: Prediction of watershed runoff resulting from precipitation events is of great interest to hydrologists. The nonlinear response of a watershed (in terms of runoff) to rainfall events makes the problem very complicated. In ...
Quantifying the Morphology of Calcareous Sands by Dynamic Image Analysis
Publisher: ASCE
Abstract: It is commonly accepted that the macroresponse of soil depends significantly on the microscopic particle characteristic features, such as size, shape, and roughness. These parameters can be obtained readily by dynamic image ...
Signal Optimization at Urban Highway Rail Grade Crossings Using an Online Adaptive Priority Strategy
Publisher: American Society of Civil Engineers
Abstract: In urban areas, conventional transit priority systems (e.g., passive priority) present some problems, such as causing too many traffic delays and degradation of on line performance due to the lack of real-time data. The ...
Formulation and Characterization of Freezing Saturated Soils
Publisher: American Society of Civil Engineers
Abstract: The writers have derived a unified governing equation for freezing saturated soils. This equation considers the governing mechanisms with respect to individual thermal and hydraulic fields. The writers included coupling ...
Reliability of Shape Factors for Bearing Capacity of Square Footings on Spatially Varying Cohesive Soils
Publisher: ASCE
Abstract: Shape factors traditionally are used to relate the bearing capacity of square, rectangular, and/or circular footings to that of strip footings in geotechnical foundation designs, in order to take account of additional ...
A FENN-TL Approach for Reliability Analysis of a Primary Ice Detection System
Publisher: ASCE
Abstract: Solving the reliability problem of primary ice detection systems is of great significance to support the design of anti-icing systems. In this paper, an efficient method employing a feature-enhanced neural network ...
