RISDiscussion of “Experimental and DEM Examinations of K0 in Sand under Different Loading Conditions” by Y. Gao and Y. H. Wang
Publisher: American Society of Civil Engineers
Time-Varying Linear and Nonlinear Structural Identification with Analytical Mode Decomposition and Hilbert Transform
Publisher: American Society of Civil Engineers
Abstract: Analytical mode decomposition (AMD) of a time series concerning any preselected bisecting frequency with Hilbert transform has been developed for closely spaced multicomponent signal decomposition. For this class of ...
Performance Prediction of Highway Asphalt Pavement Based on IFA-SVM
Publisher: ASCE
Abstract: To solve the problem of the low accuracy of the traditional qualitative method for highway asphalt pavement performance, a prediction model based on improved firefly algorithm (IFA)—support vector machine (SVM) is established ...
Study of Pore Volume Fractal Dimension for Different Air Content Cement Mortar
Publisher: American Society of Civil Engineers
Abstract: The pore structure parameter of cement mortar with different air contents was tested through Automatic Mercury Porosimeter and Air Void Analysis of Hardened Concrete. A fractal model based on the thermodynamic method was ...
Modeling and Contribution Analysis of Vibration Transfer Paths for a Dual-Rotor Aeroengine
Publisher: American Society of Civil Engineers
Abstract: In order to study the vibration transfer characteristics of a dual-rotor aeroengine system, an aeroengine system dynamic model containing high- and low-pressure rotors as well as inner and outer casings is established. The ...
