Water Use Pattern of Residential and Commercial Customers
The availability of the Automatic Meter Reading (AMR) devices make it possible to read a large number of meters in a short period of time. Through the use of AMR, we monitored weekly water...
Low Flush Plumbing Fixtures and Wastewater Systems
The significance of low flush plumbing fixtures on the wastewater collection and treatment system serving a small community has been determined. Among the concerns studied were: functional...
Use of a Statistical Model to Forecast Future Wastewater Flows
Future wastewater flows are generally predicted based upon an assumed rate of population and industry growth within a treatment facility's area of influence. In a community with limited...
Seasonal Rates?The Pros and Cons: A Case Study
The Spring Valley Water Company, an investor owned water utility serving over 58,000 customers in Rockland County, New York, implemented a seasonal differential rate structure in 1980....
Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...
Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...
Continuous Simulation Modeling for Sewer Systems
The peaking-factor method of sanitary sewer design was developed to simplify the calculations in determining design flow rates. This method of analysis is conservative to the point that...
Managing Stormwater with a Microcontroller Operated System
Concepts of managing urban stormwater runoff with a microcontroller operated flow control system are presented. The microcontroller system allows flexible and precise flow control from...
A Raft System for Large River Hydraulic Measurements
Collection of hydraulic data in large rivers is a difficult, time consuming, and occasionally perilous task. High water velocities, considerable depths, and wide channels present obstacles...
The 3D Approach to Design
Designing directly in three dimensions, including integrated analysis and information flow, is a powerful way to enhance civil engineering capabilities. Yet, relatively few have taken...
Agent-Based Technology for Facility Design Software Integration
The application of a novel technology called Agent-Based Software Engineering to facility design software integration is presented. The technology is founded on the notion of design agents...
Architecture of an Object-Oriented Product Model Prototype for Integrated Building Design
The proposed integrated building design system consists of a product modeling framework represented by a general product model and several partial knowledge bases, a conventional CAD system,...
Explanation Facilities for Intelligent Engineering Tutors
Intelligent Tutoring Systems (ITS) provide a method for humans to interact with a computer to learn about a particular topic. Usually, the ITS system has as part of its components a knowledge-based...
Simulation of ATIS Strategies to Mitigate Special Event Congestion
This research extends the performance and application of DYNASMART, a dynamic traffic simulation model which incorporates the three elements necessary for modeling traffic flow under information:...
A Real-Time Expert System for Freeway Incident Management in Orange County, California
This paper discusses the development of a prototype, multi-user, networked, real-time knowledge-based expert system (KBES) to provide decision support to California Department of Transportation...
The Hybrid Solution Approach of ESBE
ESBE is the hybrid object-oriented expert system for the optimization of construction site layout. The task is the dimensioning and the arrangement of the individual construction site...
A Knowledge-Based System for the Damage Assessment of Timber Trusses
A knowledge-based system for the maintenance of over two hundred timber Warren truss buildings is being developed at the Royal Military College of Canada by the Knowledge-Based Expert...
Decision Methods for Selecting Earth Retaining Structures
The Bridge Branch of the Colorado Department of Transportation (CDOT) has organized the framework of a formal decision process for retaining wall selection. The process facilitates implementation...
Knowledge-Based Creation of an Architectural 3-D Model from 2-D Drawings
This study is an extension of an earlier work on creating a 3-D model from 2-D drawings. The objective of this current work is to explore the issues involved in creating a prototype knowledge-based...
