Fuzzy Sets Model for Evaluation of Bridge Projects
This paper presents the formulation of a computerized decision support system that would aid the bridge engineer in long range planning of bridge funding needs, specially, to select the...
Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...
An Application of Scour Hazard Analysis and Management
A phased study for the assessment of bridge scour vulnerability is presented. Its objectives are to: (a) initiate a field assessment program, (b)establish data handling capabilities, (c)...
Implementation of the Indiana Bridge Management System
Management of a bridge system involves a complex decision-making process. A comprehensive bridge management system provides a set of tools that aid this process by selecting improvement...
Establishing a HSGT System Organization
Most of the attention on High Speed Ground Transportation systems thus far has been devoted to their technological, financial and construction aspects, and this was understandable since...
A Combined Noise Model for HSGT Traffic
Environmental concerns are high on the list of possible problem areas for proposed high speed ground transportation (HSGT) systems. A Federal Highway Administration (FHWA) Highway Traffic...
Estimating the Ground Transportation Impacts of the Maglev System
This paper will examine the planning process required to conduct a transportation analysis for a high speed ground transportation system, utilizing the Orlando experience as an example....
Development of Simulation and Cost Models to Compare HSR and Maglev Systems
Both high-speed rail (HSR) and magnetically levitated systems offer comfortable and safe ground transportation at high speed. The cost structure and performance of these systems and their...
Automation for Design of High Speed Rail Alignments
The widespread industry practice of using civil engineering software modified for the design of High Speed Rail alignment is inefficient and produces inadequate results. Advances in computer...
The Use of Multibody Software in the Wheel/Rail Contact as Applied to Very High Speed Tests
How strange may it be, the behaviour of railway vehicles depend on contact forces developing between wheels and rails inside patches of no more than 1 cm2....
Implementation and Maintenance of a TGV Line
Because of the success of the TGV in France since the opening date in 1981, SNCF plans to implement 2800 miles of new line in the next 20 years. A new line project poses two management...
The TGV Rolling Stock?Its Evolution and Capabilities
The TGV has achieved a revolution in passenger rail service in France and in Europe. The subject of this paper is the TGV rolling stock, the distribution between three generations, the...
Making the Leap
Over the past decade, computers have become as much a part of the engineering field as concrete and steel. But bringing a firm into the information age can be complicated and expensive....
Runway Rehab: A Case for CADD
Hired to design and monitor construction at Boston's Logan Airport, engineers at S E A Consultant's quickly realized that they would have to supplement their...
Landfill on Screen
Engineers for a $3.7 million regional landfill in Iowa turned to computer-aided design at every project step from conceptual design through operations monitoring following construction....
Production and Decomposition of
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...
A Workstation for the Extraction of Coastline from Digital Imagery
The delineation of coastline has primarily been a manual tracing exercise from various forms of imagery. In this paper, a process to extract shoreline automatically from digital imagery...
Shoreline Erosion Assessment Software (SEASware)
This paper describes the shoreline erosion assessment software SEASware....
Evaluation of Airborne Video Imagery for Distinguishing Intertidal Oyster Reefs
We evaluated the effectiveness of airborne video imagery in distinguishing and mapping oyster (Crassostrea virginica) reefs in Aransas Bay on the southern Texas gulf coast. Imagery obtained...
