Molluscan Communities of Laguna Madre, Texas: Man's Impact
The purpose of this study is to test the hypothesis that due to human intervention the two parts of the Laguna Madre now differ in molluscan species composition and the most heavily-impacted...

Taxing Response Evasion on the Great Barrier Reef
A class of models known as randomized response designs has been shown to reduce survey response bias to incriminating questions by assuring respondent confidentiality. The purpose of this...

Automated Permit Review for Hazardous Waste Surface Impoundments
The United States Environmental Protection Agency has proposed to develop automated permit review for RCRA hazardous waste surface impoundment facilities. The review automation will consist...

Automated Water Control in Southern Alberta
The distributed control system for water delivery that has evolved in Alberta, Canada is described including the type of hardware used and the general operating philosophy. Of importance...

Groundwater Recharge Demonstration Projects
In dry climates, natural replenishment rates of aquifers (safe yields) are quite small. Many of these aquifers are being depleted. This is giving rise to an increasing interest in artificial...

ENDOW, An Expert System for Screening Environmental Features for Stream Alternations
This paper discusses development of an expert system for Environmental Design of Waterways Projects (ENDOW) by stream alteration specialists who were novices in artificial intelligence....

Expert System for Mixing Zone Analysis of Toxic and Conventional Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software subsystems for the analysis, prediction and design of aqueous toxic or conventional pollutant discharges into watercourses...

Risk Assessment for Cladding Panels: An Expert Systems Approach
Risk assessment for structures in the context of wind engineering involves many factors such as wind hazard, the wind sensitivity of the structure and the socio-economic value of the structure....

Microcomputer Expert Systems in Transportation Engineering
This paper reviews microcomputer-based expert systems in transportation engineering. Expert systems have great potential for solving ill-structured problems and for becoming useful tools...

Expert Systems for Traffic Signal Control
The level of service achieved by a pretimed signal timing control strategy implemented at an isolated intersection incurring saturated and over-saturated demand varies with actual traffic...

Expert System for Transportation Corridors
Semantic nets and frame representations are used by an expert system under development to assist in the selection of projects and control strategies in transportation corridors. The project...

Expert Systems Approach for Analysis of High Hazard Locations
This paper focuses on the detailed analysis of specific highway locations that have been identified as hazardous in the framework of a State Highway Safety Improvement Program (HSIP)....

Earthquakes Will Not Damage This Bridge
A California pipeline bridge has been retrofitted with isolation bearings that damp earthquake shocks. The bridge over Southern California's Santa Ana River carries the Upper...

Fast Exit
A new runway to be built at Orlando International Airport in Florida has been designed with taxiway exits based on spiral geometry that give the pilot a gentle angle for exit and a graduated...

A Knowledge-Based Approach to Improve Urban Transportation Decision-Making
This paper describes a microcomputer-based tool that has been developed to facilitate acquisition and improvement of skills in urban transportation decision-making, in an educational environment....

Uprating Francis Turbines Provides Additional Energy
The use of existing powerhouse, penstocks, dams and unit configuration, all provide for a quick cost effective method to increase output from an existing turbine installation. This paper...

Expert Systems and Engineering Design Knowledge
As in many current AI (Artificial Intelligence) systems, knowledge processing is the most important issue in expert systems. 'Knowledge' in engineering applications...

Expert Opinions and Expert Systems
The inference mechanism in most current expert (rule-based production) systems is based on exact matching of the antecedent or consequent of a rule with a fact or hypothesis. The rule...

Applications of Artificial Intelligence in Preliminary Structural Design
The field of Artificial Intelligence (AI) deals with the problems of modeling human intelligence. The application of AI to structural engineering has been limited, but potential applications...

Proposed Operation of an Expert System for Analyzing Construction Project Risks
The principal problem for the construction project manager is selecting the most effective response when project progress deviates undesirably from targeted objectives. Optimally, the...
