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...

Bonded Concrete Overlays for Rehabilitation of Continuously Reinforced Concrete Pavement
As a result of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA), significant funding is now available for the rehabilitation of the nation's Interstate highway system....

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...

Digital Image Processing and Analysis in Materials Science (Keynote Lecture)
This discussion presents a generic overview of computer aided imaging in materials science. Some of the questions to be answered are: Does the computer perceive the same things that I...

Multispectral/Hyperspectral Imaging and Data Compression
Remote sensing instrumentation, data and analysis techniques for Civil Engineering applications are similar to those used in multidisciplinary remote sensing of the earth's surface. Data...

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...

Machine Vision Based Traffic-Adjusted Intersection Signal Control
This paper describes some of the available machine vision systems and how they can be effectively used for traffic control at an intersection. A set of rules have been defined which make...

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...

Ground Penetrating Radar: Images of Subsurface Characteristics
Ground penetrating radar has not been widely used for subsurface exploration in Civil Engineering. This paper describes the experimental setup used to explore ground penetrating radar...

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...

Image Enhancement: Application to Geotomography
Image enhancement complements geotomographic reconstruction in the rendering of better images. In this paper, available image enhancement techniques are reviewed. Emphasis is given to...

Application of Digital Images and Processing for As-Built Construction Drawings
The production of as-built drawings is a labor intensive activity that often provides the facility owner with inaccurate or incomplete final drawings. This paper briefly reviews work accomplished...

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...

Image Analysis Applied to Geotechnical Engineering
Application of scanning electron microscope and image analyzer to the quantification of grain morphology and microfabric of aged sands is briefly reviewed. Relationships of morphology...

Evaluation of Runway Roughness for Fighter Jets
A new roughness evaluation procedure is needed, especially, when dealing with modern fighter jets. To this end, a comprehensive pilot attitude survey was conducted in Israel in order to...
