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...

Steel Exoskeleton Defines Architecture
The Hotel de las Artes multi-use complex in Barcelona, Spain consists of a luxury hotel/apartment tower, a commercial office building, retail, parking and other amenities. The most prominent...

Nondestructive Testing Role in Repair and Rehabilitation of Concrete Structures
Nondestructive testing (NDT) methods are increasingly being used to assess the condition of structural concrete. The paper discusses applications of NDT methods for forensic investigation...

Assessment and Repair of Fire-Damaged Concrete Structures
Concrete, even though it may be the most fire-resistant of all the major building materials, can be damaged by fire. Seldom does even a major fire cause total destruction, however, most...

Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures
As with other forms of infrastructure, there is an ever increasing need to repair and strengthen unbonded post-tensioned concrete structures. Repairs may be necessitated for a variety...

Use of CLSM Fly Ash Slurry for Underground Facilities
This paper presents the results of research performed in developing and using flowable fly ash slurry which falls under the classification of Controlled Low Strength Material (CLSM) as...

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...

Application of Digital Image Processing in Morphological Analysis of Geotextiles
Geotextile filters are rapidly replacing graded granular filters in dams, landfills, edge drains, and retaining walls. The design of these filters requires morphological information about...

Application of Radar Imaging Techniques to Concrete
Wideband radar imaging techniques have the potential of being a powerful tool in detecting steel reinforcing bars and delaminations inside concrete. The success of the method as a nondestructive...

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...

Finite Element Analysis of Slabs-on-Grade Using Higher Order Subgrade Soil Models
Incorporation of the two-parameter, Kerr and Zhemochkin-Sinitsyn-Shtaerman subgrade models into finite element code ILLI-SLAB is described. The two conventional idealizations, namely the...
