Competitive Advantage of Using Computers in Structural Design
More and more structural analysis and design work is done using computers. The trend will continue because the software is becoming more powerful and the cost of computers is falling....
Model-Based and Interactive Planning for Predictive Plant Maintenance Management
Maintenance of process in power plants represents about 30% of the operating cost of these plants, including the cost of repair labor, materials and out side services but not the cost...
Fit to Drink
Amendments to the Safe Drinking Water Act (SWDA) in 1986 greatly expanded the number of contaminants subject to regulation and significantly beefed up water quality treatment and monitoring...
Highway Investment Analysis: The Next Generation
The Department of Transportation has developed and is now testing a state-of-the-art modeling procedure which simulates highway improvement selection decisions based on the relative benefits/cost...
Cost-Benefit Evaluation of Network Level Pavement Management
This paper presents a cost-benefit analysis prepared for senior management. It uses the Alberta pavement management system as the primary case, and the Arizona PMS system as the second...
TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
Aggregate Quarry Operations?From a Railroad's Perspective
This paper describes a study which shows how a railroad company can ensure receipt of a cost-effective, high-quality aggregate product for ballast by monitoring selected quarry operations....
Evaluation of HSGT Systems Under Uncertainty
The basic themes of this paper are two-fold. First we investigate what planning style is likely to be most suited for planning an HSGT system, dependent on three interdependent key variables:...
California-Nevada Superspeed Train Experience and Outlook
The experience of the California-Nevada Superspeed Train is chronicled from its inception in 1970 to the present. The evolution of the route alignment and technology selection are presented,...
High-Speed Surface Transportation Cost Estimating
The cost of building and operating high-speed surface transportation (HSST) systems in the United States is a critical factor in determining their feasibility. Costs are difficult to estimate...
Maglev vs. High Speed Rail in the Quebec City-Windsor Corridor: A Comparison of Costs and Revenues
This paper reports an investigation of cost and revenue for high speed rail vs. maglev systems serving selected links in the Quebec City-Windsor Corridor (Canada). Information on the Corridor...
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...
Application of the Maglev System in Germany
After the unification of Germany in 1991, the Federal Government decided to investigate Maglev links between the old and new Federal States to cope with the considerable increase of East-West...
The Transrapid Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application and is under consideration for several sites in the U.S. The maglev system...
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...
Ecological Costs of Urban Expansion in a Mangrove Ecosystem: A Case Studied
On Santa Catarina Island in southern Brazil, mangrove systems are found along about 14.7% of this coast. These areas, although declared by legislation as 'Permanent Preservation Areas',...
Dune Erosion Management: a Cost Benefit Analysis
A method is presented and illustrated to establish economically justifiable coastal protection measures to reduce storm damage. This method can be used in the initial design stage of a...
Potential for the Bioremediation of Contaminated Dredge Material
Sediment contamination frequently impacts the ability of ports to maintain and deepen shipping channels. One of the common contaminants in channel sediments is polycyclic aromatic hydrocarbons...
Optimization of Beach Fill Transitions
Accentuated erosion or end loss by excessive longshores and transport occurring at abrupt lateral terminations of beach fills can compromise a fill's shore-protection functioning and longevity....
