RISEstimating the Frequency of Exposure to Uncertain Hazards: Impact of Wind Conditions on Concrete Dam Construction
Publisher: ASCE
Abstract: Due to the narrow construction site, intensive construction, and constant strong winds, some concurrent activities during concrete dam construction are proven to lead to space conflicts and increase the frequency of exposure ...
Risk Propagation in Multilayer Heterogeneous Network of Coupled System of Large Engineering Project
Publisher: ASCE
Abstract: Because of the long duration, multiplicity of technical disciplines, large number of project stakeholders, and high levels of complexity and uncertainty, project risk propagation control in large engineering projects (LEPs) ...
Human Error Analysis for Hydraulic Engineering: Comprehensive System to Reveal Accident Evolution Process with Text Knowledge
Publisher: ASCE
Abstract: Many human errors occur in hydraulic engineering construction, and these errors may lead to huge financial losses. A systematic and comprehensive accident analysis is required to reduce the probability of human error. Human ...
Response of Water and Nitrogen Losses to Water Management Practices and Green Manure Application in Lowland Paddy Fields
Publisher: American Society of Civil Engineers
Abstract: The complexity of agricultural water management practices has challenged researchers attempting to determine how hydrological pathways affect water and nitrogen (N) losses. Field experiments in a typical rice agricultural ...
Machine Learning Approach to Decomposing Arterial Travel Time Using a Hidden Markov Model with Genetic Algorithm
Publisher: American Society of Civil Engineers
Abstract: Bluetooth-based traffic detection is an emerging travel time collection technique; however, its use on arterials has been limited due to several challenges. In particular, data missing not at random (MNAR) is a common data ...
Nonstationary Stochastic Simulation–Based Water Allocation Method for Regional Water Management
Publisher: American Society of Civil Engineers
Abstract: Due to climate change and human activities, the assumption of the stationarity of hydrological variables will no longer hold. Moreover, the stochastic uncertainty of hydrological variables introduces huge challenges for ...
Novel Probabilistic Cost Estimation Model Integrating Risk Allocation and Claim in Hydropower Project
Publisher: ASCE
Abstract: The uncertain construction of hydropower projects and fierce market competition put forward more stringent requirements for contractors with regard to accuracy and competitiveness of cost estimation. However, previous ...
Determination of Optimized Rectangular Spreader Thickness for Lower Thermal Spreading Resistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents an approximation for determining an optimized thickness of a concentric heated rectangular plate and derives an analytical solution for spreading resistance of a spreader ...
Investigations of the Thermal Spreading Effects of Rectangular Conduction Plates and Vapor Chamber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines the spreading ability of rectangular plates numerically, analytically, and experimentally. The effect of aspect ratio, defined as an equivalent radius of a heater divided by ...
