Multiparty Model Development Using Object-Oriented Programming
The Massachusetts Water Resources Authority (MWRA) has taken advantage of recent advances in object oriented programming to build a flexible input and output model of its water supply...

Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...

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...

Interactive Decision Support for Hydrologic, Hydraulic, & Instream Flow Criteria
Most often, impacts on natural resources from alternative river discharges are not quantified. The personal computer (PC) can provide access to useful techniques for analyzing multiobjective...

Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...

F. E. Everett Turnpike: An Application of MOSS
MOSS surface modeling software is being used successfully by Fay, Spofford & Thorndike, Inc., on a major project for the New Hampshire Department of Transportation to make improvements...

NOISE?A Comprehensive Software Library for Highway Noise Analysis
The Noise Software Library is a collection of highway noise analysis software tools that are arranged together under a powerful file management system which provides a transparent method...

The Application of AI in Highway CAD System
In a conventional CAD System, the process for solving a certain particular engineering problem is fixed stationary in the program. As a result, the program is often modified to fit different...

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...

Designing in Three Dimensions for Manufacturing Facilities
Du Pont Engineering is using Three-Dimensional Design for the design of our manufacturing facilities. Our 3D design system was used on several projects in 1992, and full implementation...

Object Oriented Modeling of Structural Systems
Computational engineering in structural design is no longer restricted to numerical approaches. Increasingly, also non-numerical, in particular, cognitive problems can be implemented into...

Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...

Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....

Computing with Objects: What Does Industry Hope to Gain from it
Although the need for an integration of engineering tasks has been stressed for a long time, the success that we see in this regard is very limited. We believe that there is justified...

A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...

A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...

CAD Applications for Material Handling in the Construction Environment
Research at Va. Tech in the area of dynamic behavior modeling and crane damping have been undertaken. The dynamic behavior modeling capability has been designed to us 3-D CAD models and...

Knowledge and Information Processing with Drawing Objects in Construction Phase
Knowledge processing by CAD systems poses challenging problems for the efficient integration of design and construction processes. While CAD systems have been applied to various phases...

Comprehensive Site Monitoring Through Model Based Reasoning
The authors of this paper have developed a computer object oriented intelligent construction site modeler which is dynamically linked to a 3D CAD system. Model Based Reasoning is used...

Advanced Construction Technology System
The Advanced Construction Technology System (ACTS) is a computer database for the classification, documentation, storage and retrieval of information about emerging construction technologies....
