Cost Considerations in Planning Pier Terminals
The deregulation of the air transport economy is gradually leading to the involvement of private developers in airport terminal financing. Even the airports run by government agencies...
Airports and Air Quality Issues - the European Perspective
This paper presents a detailed review of air quality studies at European Airports since 1986. It also provides a brief analysis of the air quality section of a recent ACI (Europe) environmental...
Site Characterization by Artificial Neural Networks
Recently, an optimal groundwater management model has been developed to treat groundwater remediation problems at Lawrence Livermore National Laboratory (LLNL). The objective of the model...
Genetic Algorithms and Neural Networks: Do Pluralized Techniques Hold Any Advantages for Designing Groundwater Quality Assurance Systems?
Methods have recently been developed for designing groundwater monitoring and pollutant containment systems. These methods rely on a variety of new and classical optimization and modeling...
Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Classification of Problem Types
Design and operation of hydraulic systems can be an extremely complex task. Although not widely accepted the application of deterministic optimization techniques can provide guidance to...
Prediction of Gravel Bedload with SAM
Bedload measurements for Little Beaver Creek in Colorado were used to test the sediment transport functions included in SAM. The test results showed that Toffaleti predicts total bedload...
Procedures for Evaluating the Effects of Sedimentation on Flood Hazards in Urbanized Areas in the Southwestern U.S.
Urbanization of watersheds in the arid Southwestern U.S. creates problems for resource agencies and design engineers. Traditional analytical techniques that are generally applicable to...
Development of Missouri River Navigation Analysis
The navigation analysis for the Master Manual review examined mainstem reservoir regulation alternatives by evaluating the benefits of reservoir releases for barge transportation. Navigation...
Public Involvement and Participation: Planning Imperatives for the Coming Century
The literature has identified three types of responses to natural resources planning and management efforts in the United States. The first focused upon the more effective use of existing...
The Channel Tunnel: Larger Than Life, and Late
The Channel tunnel opens in May, but passenger service will be delayed while final testing on trains and electrical systems are completed. The English Channel tunnel crossing is the world's...
Quantification of Cost Uncertainties Using Neural Network Technique
This paper describes the development of a neural network system for forecasting cost escalation in construction. The input of the neural network system consists of factors that have an...
Intelligent Tutoring Systems to Aid Water Treatment Plant Operators
Training for water treatment plant operators exists primarily through short courses at colleges or technical schools, self-study manuals, and on-the-job training. Intelligent tutoring...
Estimating Clay Liner and Cover Permeability Using Computational Neural Networks
The ability to provide a quick estimate of the permeability value to be expected in laboratory testing (of field samples) would help to predict potential problems in meeting the permeability...
Development of an Expert System to Identify Hazardous Highway Spots
The paper describes the development of an expert system within a geographic information system to identify high-hazard spots in a highway network. The philosophy guiding expert system...
Selecting Precast Concrete Building Systems
The development of an integrated computer system to assist in the selection of precast concrete (PC) building systems is described. StructNet, a neural network program, identifies possible...
Global Network Optimization for Pavement Management
In a state-wide pavement management system, the highway network can be divided into a number of road categories based on traffic level and geographical region. Network optimization analysis...
The Application of Artificial Neural Networks to Civil Engineering
Recently, there has been much interest in the application of artificial neural networks (ANNs) to civil engineering problems. Most applications, however, have been limited to the use of...
