RISRelationship between Mean Value and Fourier Coefficients of a Time-Varying Function with Half-Period Rests: Theory and Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Fourier coefficients are investigated for such a periodic time function whose magnitude keeps constant during the time of every half-period. In this case the relationship between the mean ...
Simultaneous and Sequential Photosonolysis of TCE and PCE
Publisher: American Society of Civil Engineers
Abstract: Aqueous solutions of trichloroethylene (TCE) and tetrachloroethylene (PCE) were treated in a flow-through reactor equipped with ultrasound and ultraviolet light sources. The reactor was operated as sonolysis (US), photolysis ...
Analysis of Maintenance Policies for Inductive Loop Detection Systems
Publisher: American Society of Civil Engineers
Abstract: Maintaining inductive loop detection (ILD) systems in good conditions is a requirement for systems to perform the functions for which they are designed. The objective of this study was to evaluate the typical maintenance ...
Modeling the Deterioration of Inductive Loops
Publisher: American Society of Civil Engineers
Abstract: Inductive loop detectors have been widely used in transportation system, particularly to monitor the performance of highway systems such as traffic flow, speed, and vehicle classification. Accurate data are dependent on ...
Numerical Simulation of a Road Deicing System Based on Resistor Network
Publisher: American Society of Civil Engineers
Abstract: This paper investigated the mechanism of resistor network for road deicing with finite element analysis. It also derived the differential equations and boundary conditions of a mathematical model during numerical analysis, ...
Estimating Highway Capacity Considering Two-Regime Models
Publisher: American Society of Civil Engineers
Abstract: Capacity can be derived by fitting a relationship between the three fundamental traffic variables: flow, speed, and density. The study uses a dual-regime model with the consideration of all three variables. Different forms ...
Clustering Number Determination for Sparse Component Analysis during Output-Only Modal Identification
Publisher: American Society of Civil Engineers
Abstract: Output-only modal identification plays an important role in the structural health monitoring of large-scale structures. In recent years, blind source separation (BSS) has achieved great success in structural modal ...
Regulation of Planting Structure Considering Irrigation Water, Carbon Emission, and Grain Security in the Yellow River Basin, China, by Using Multisource Data
Publisher: ASCE
Abstract: Grain security is the foundation for national stability and prosperity. In China, grain production depends heavily on irrigation water, direct energy for machinery use, and indirect energy (such as fertilizers, pesticides, ...
Fully Automated Operational Modal Identification Using Continuously Monitoring Data of Bridge Structures
Publisher: ASCE
Abstract: Structural modal identification for providing dynamic properties, including frequencies, damping ratios, and mode shapes, plays an important role in structural health monitoring and safety assessment. Automated modal ...
