Liquefaction Analysis in a GIS Environment
Liquefaction has been identified as one of the seismic hazards that brings great damage to property and infrastructure, and loss of life. The need for liquefaction analysis that works...

Liquefaction Potential of Western Puerto Rico
The historical seismic record, paleoseismic evidence, high population density, time expired since the last major earthquake, and the presence of liquefiable sands and soft clays combine...

Development of Geographical Information System (GIS) for Seismic Hazard Study of Charleston, SC
One of the most prominent areas of seismicity in the eastern U.S. is near Charleston, SC. The 1886 Charleston earthquake (M=7,5) and liquefaction evidence from at least five prehistoric...

CALTRANS Seismic Hazard/Risk Map and Proposed GIS Applications
The California Department of Transportation (CALTRANS) considers earthquake effects in planning, design, and construction of their structures. Obviously, CALTRANS has to respond to damaging...

A Prospect for Liquefaction Hazard Evaluation Using GIS
A brief description of a recently developed methodology to evaluate liquefaction hazard at a site is presented. In this method, uncertainty and scatter in the data are considered rigorously....

A Geotechnically-Oriented GIS for Seismic Hazard Mapping
A geotechnical GIS has been configured by the California Department of Conservation's Division of Mines and Geology for the purpose of designating seismic hazard zones as mandated by recent...

State of the Art in Spatial Data Transfer: FIPS 173
This paper provides an overview of Federal information processing standard (FIPS) 173. FIPS 173 is a comprehensive spatial data transfer standard that provides solutions to the problem...

Potential Role of GIS in Geotechnical Earthquake Engineering Studies at U.S. Army WES
The U.S. Army Corps of Engineers (USACE) was one of the original developers of Geographic Information Systems (GIS) and continues to be active in related research (U.S. Army Engineer Construction...

Accessibility of Geotechnical Earthquake Engineering Data and the Need for Data Storage and Dissemination Standards
Ease of data access and data standards are two issues critical to the success of GIS technology when applied to earthquake hazards research problems that require geotechnical engineering...

Towards a Common Data Exchange Format Between Geographic Information Systems
To make their respective geographic information systems (GIS) software packages more useful to the user community, the GIS software vendors have steady added various database translators...

DART'S ASAP EIS
An environmental impact statement that takes several years to complete can demoralize the staffers behind a transportation project and reduce public support for the effort. In a hurry...

Digital Image Processing: Experiences in the Gulf War
During the 1990-91 conflict in Southwest Asia between Iraq and coalition forces operating with US Armed Forces, the utility of products developed from digital imagery and digital terrain...

Morphological Methods for Characterizing Inter-feature Distances
Characterizing inter-feature distances in digital images using automatic image analysis systems presents problems not found when quantifying the morphology of the features themselves....

Multi-Paradigm Learning Algorithms for Image Recognition
Several recently-developed machine learning algorithms for the image recognition problem are reviewed. They are based on adroit integration of various recent and emerging technologies...

Image Analysis of Clay Microstructure
The paper summarises new methods which have been developed to analyse oriented textures in electron micrographs of clay soils, complementary methods using polarising microscopy, and an...

Digital Evaluation of Contaminated Sites
This paper introduces digital techniques to evaluate historical maps and aerial photographs in order to detect contaminations on derelict industrial sites. Special attention is paid to...

Survey of Image Processing Applications in Civil Engineering
A number of imaging products have been developed for civil engineering applications. This paper attempts to survey various image processing applications in civil engineering up to date....

Computer Vision Techniques for Comparing Laser Doppler Velocimeter Scans of a Vibrating Plate to Analytical Plate Modes
Computer vision procedures were applied to velocity images of a vibrating square steel plate. A scanning laser Doppler velocimeter (LDV) measured the images of low frequency resonant operating...

Optimal Region Aggregation with Shape Considerations in Spatial Optimization
The region aggregation (land acquisition) problem is discussed within the context of a regular grid matrix having representative cell indices or attribute values. Several optimization...

An Introduction to APM Systems and Applications
An Automated People Mover (APM) is an advanced transportation system in which automated driveless vehicles operate on fixed guideways in exclusive rights-of-way. These differ from other...
