Multi-Sensor Information Fusion Kalman Filter Weighted by Scalars for Systems with Colored Measurement Noises
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An optimal information fusion criterion weighted by scalars is presented in the linear minimum variance sense. Based on this fusion criterion, a scalar weighting information fusion decentralized ...
Damage Detection Strategy Using Strain-Mode Residual Trends for Long-Span Bridges
Publisher: American Society of Civil Engineers
Abstract: In this paper, a damage detection strategy based on distributed strain responses measured by long-gauge fiber Bragg grating (FBG) sensors is investigated. First, the distributed strain modes of a system with multiple degrees ...
Reduction of Low-MW Model Compounds by Ozonation and O3 ∕UV Processes
Publisher: American Society of Civil Engineers
Abstract: In this investigation, the low-molecular-weight organic matters, such as resorcinol, phloroglucinol, and
Optimization of Regional Water Distribution System with Blending Requirements
Publisher: American Society of Civil Engineers
Abstract: In a multisource, multiquality regional water distribution system, water agencies often find that it is necessary to impose blending requirements at certain control points in the system in order to secure the desired water ...
Water Distribution Network Reliability: Connectivity Analysis
Publisher: American Society of Civil Engineers
Abstract: This paper presents a methodology to analyze the reliability of a regional water distribution network. The proposed reliability analysis method focuses on the impact of link failures on source-demand connectivity, which ...
Water Distribution Network Reliability: Stochastic Simulation
Publisher: American Society of Civil Engineers
Abstract: Stochastic simulation is applied in a reliability analysis of a regional water distribution network. To complement the connectivity-based reliability analysis presented in the companion paper, the proposed stochastic ...
Safety and Stability of Light-Rail Train Running on Multispan Bridges with Deformation
Publisher: American Society of Civil Engineers
Abstract: This study investigated the safety and stability of light-rail trains that run on multispan simply supported bridges (MSSBs) and have experienced some settling and girder deformation caused by both foundation settlement ...
Effect of Bromide and Ammonia on the Formation of Ozonation and Chlorination By-Products
Publisher: American Society of Civil Engineers
Abstract: The objective of this investigation was performed to assess the effects of bromide and ammonia concentrations on the formation of ozonation and chlorination by-products including bromate, trihalomethanes (THMs), and ...
Modeling Reservoir Evaporation Losses by Generalized Networks
Publisher: American Society of Civil Engineers
Abstract: Using a generalized network formulation, the nonlinear evaporation loss function of a reservoir is directly incorporated in a water-supply-optimization model. The nonlinear function is first piecewise-linearized and the ...
Effect of Sand Mining on Bridge Capacity and Safety under the Bridge
Publisher: American Society of Civil Engineers
Abstract: Sand excavations at river beds have compromised the safety of several bridges in recent years. An expressway that connects a huge line bridge is selected as the research object in this study. The phenomenon of the excessive ...
