Interferometric Imaging: Involvement in Civil Engineering
(American Society of Civil Engineers, 1999)Civil engineering is making an increasing use of modern interferometric imaging methods in various types of measurements. This paper attempts to clarify the present and potential role of such methods in this discipline. ... -
Subsurface Characterization Using Artificial Neural Network and GIS
(American Society of Civil Engineers, 1999)A method for characterizing the subsurface is developed using an artificial neural network (ANN) and geographic information system (GIS). Data on the distribution of aquifer materials from monitoring well lithologic logs ... -
Comparison of Case-Based Reasoning and Artificial Neural Networks
(American Society of Civil Engineers, 1999)The outcome of construction litigation depends on a large number of factors. To predict the outcome of such litigation is difficult because of the complex interrelationships between these many factors. Two attempts are ... -
Applications and Issues of GIS as Tool for Civil Engineering Modeling
(American Society of Civil Engineers, 1999)A tool that has proliferated within civil engineering in recent years is geographic information systems (GIS). The goal of a tool is to supplement ability and knowledge that already exists, not to serve as a replacement ... -
Soil Particle Size Distribution by Mosaic Imaging and Watershed Analysis
(American Society of Civil Engineers, 1999)A new method is presented for obtaining soil grain size distribution curves from digital images of a soil specimen. The technique offers several improvements over existing methods by adapting mosaic imaging and watershed ... -
Robust Water System Design with Commercial Intelligent Search Optimizers
(American Society of Civil Engineers, 1999)Intelligent-search-based optimizers have shown promise in providing improved links between analysis and design. Genetic-algorithm-based optimizers are often used, but other heuristic methods, such as tabu search, have also ... -
Analysis of Masonry Panel under Biaxial Bending Using ANNs and CBR
(American Society of Civil Engineers, 1999)In this paper the capability of artificial neural networks (ANNs) in solving complex nonlinear problems is utilized for the analysis of masonry panels under biaxial bending. A network, trained using a set of data, which ... -
