RISTheoretical Investigation of Leak’s Impact on Normal Modes of a Water–Filled Pipe: Small to Large Leak Impedance
Publisher: American Society of Civil Engineers
Abstract: Recent research shows the potential of resonant frequency-based leakage detection methods. However, there is a disagreement in whether a leak shifts the normal modes (often called natural or resonant modes) and whether a ...

Usage and Effect of Multiple Transient Tests for Pipeline Leak Detection
Publisher: ASCE
Abstract: The value of multiple transient tests under the same experimental conditions for the purpose of leakage detection is assessed. The gain in signal-to-noise ratio and leakage detection accuracy due to the multiple tests are ...
Model-Free Matched Field Processing for Condition Assessment of Pressurized Pipes
Publisher: ASCE
Abstract: Many transient-based defect detection methods are based on matching the transient model to the measured data to localize the defects. Despite the high degree of success in laboratory systems, this approach has not been ...
Predicting the Performance of System for the Co-production of Fischer-Tropsch Synthetic Liquid and Power from Coal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A co-production system based on Fischer-Tropsch (FT) synthesis reactor and gas turbine was simulated and analyzed. Syngas from entrained bed coal gasification was used as feedstock of the ...
Linear Model and Regularization for Transient Wave–Based Pipeline-Condition Assessment
Publisher: ASCE
Abstract: Condition assessment or defect detection of a pipeline is a difficult inverse problem. This paper proposes a general linear model framework that can approximately describe a wide range of pipeline condition assessment and ...
Cramer-Rao Lower Bound for Performance Analysis of Leak Detection
Publisher: American Society of Civil Engineers
Abstract: Due to random noise in real measurements, leak detection (estimation of leak size and location) is subject to a degree of uncertainty. This paper provides a framework to investigate the lower bound of the variance of a ...

Blast Risk Assessment of Wood Residential Buildings: West Fertilizer Plant Explosion Case
Publisher: ASCE
Abstract: To predict the hazard-induced risks of buildings and infrastructures and assess the losses caused by hazards, the fragility curve method is a common quantitative risk assessment procedure for civil structures. It has been ...
Influence of Growth Ring Orientation on the Interlaminar Fracture Toughness in Glued-Laminated Timber
Publisher: American Society of Civil Engineers
Abstract: In glued-laminated timber (glulam), fracture may occur at the interface of two adjacent laminae that mostly have different growth ring orientations. The double cantilever beam (DCB) tests for Mode I fractures and three-point ...
