Efficient Parallel Implementation of Hybrid Optimization Approaches for Solving Groundwater Inverse Problems
Publisher: American Society of Civil Engineers
Abstract: Inverse problems that are constrained by large-scale partial differential equation (PDE) systems demand very large computational resources. Solutions to these problems generally require the solution of a large number of ...
Finding All-Pairs Shortest Path for a Large-Scale Transportation Network Using Parallel Floyd-Warshall and Parallel Dijkstra Algorithms
Publisher: American Society of Civil Engineers
Abstract: Parallel computing has become a powerful approach for solving real-time decisions about large-scale, computing-intensive transportation problems. A frequently encountered transportation problem is the “shortest path problem;” ...
Hybrid Genetic Algorithm—Local Search Methods for Solving Groundwater Source Identification Inverse Problems
Publisher: American Society of Civil Engineers
Abstract: Identifying contaminant sources in groundwater is important for developing effective remediation strategies and identifying responsible parties in a contamination incident. Groundwater source identification problems require ...
Successive Linear Approximation Methods for Leak Detection in Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: In many modern water networks, an emerging trend is to measure pressure at various points in the network for operational reasons. Because leaks typically induce a signature on pressure, these routine measurements can be ...
Correcting Power Leakage Equation for Improved Leakage Modeling and Detection
Publisher: ASCE
Abstract: Fluid pressure influences leakage flow rate in water distribution pipe networks. Significant progress has been made in the use of pressure management techniques to control leakage. An empirical power equation (known as the ...
Genetic Algorithm-Based Decision Support for Optimizing Seismic Response of Piping Systems
Publisher: American Society of Civil Engineers
Abstract: This paper describes computational approaches used in a prototype decision support system (DSS) for seismic design and performance evaluation of piping supports. The DSS is primarily based on a genetic algorithm (GA) that ...
