Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...

Object-oriented River System Simulation
This paper describes an object-oriented approach to river basin simulation modeling that is event driven rather than time driven as in most river system simulation models. At the heart...

Optimum Operation of Recharge Basins
Mathematical models based on nonlinear programming are developed for operating recharge basin systems. The objective of these optimization models is to determine the operation policy that...

Artificial Recharge to Manage Groundwater Quality in a Connected Surface Water Groundwater System
Finite difference method is used to formulate the management problem of movement of water and solute in a connected surface water groundwater system. Pumped groundwater quality of conservative...

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...

Interdisciplinary Communication of Design Critique in the Conceptual Design Stage
Computer tools provide little support for the communication of design concepts and problems across disciplines. Our objective is to help bridge the communication gap between architects...

A Structural Engineering Education Image Database
An interactive multimedia environment has been developed to allow students and instructors access to digital images from case studies of structures and structural failures. In this multimedia...

Integrating Qualitative and Quantitative Reasoning in Structural Engineering
Qualitative reasoning has applications in engineering problem solving and the development of intelligent computer-aided engineering tools. Most applications in structural engineering have...

Deriving Alternative Structural Modifications Based on Qualitative Interpretation at the Conceptual Design Stage
Current computer tools provide little support in deriving alternative modifications based on qualitative structural interpretation of a conceptual design. This paper presents a behavior-based...

Implementing Qualitative Reasoning for Structural Design Using Constraint Propagation
All designs begin with qualitative reasoning and therefore, this activity has an important influence upon subsequent quantitative stages. In structural design, qualitative reasoning starts...

Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...

Order of Magnitude Reasoning for Qualitative Matrix Structural Analysis
Several computational schemes have recently been proposed to adapt Qualitative Reasoning for Structural Engineering applications. One current methodology. Qualitative Matrix Analysis (QMA),...

A Comparison of Two AI Based Design Systems
Two applications of Civil Engineering based, AI systems are described. Although both systems are intended as design aids they have substantially different structures and methods of achieving...

NETSYN: Neural Network-based Support for Synthesis
Our goal in applying machine learning for synthesis is to develop a tool that assists in acquiring the relationships between form, function, and behavior properties that can be used to...

Intelligent Systems for Information Retrieval in Construction
The last three decades of the scientific and business market have been signed by information revolution. In construction, large amounts of information are manipulated and consulted. Information...

Creative Engineering Design Using Analogy
Designs in different domains vary in structure, performance and in many other aspects. However, their design purposes can be achieved in a limited number of ways. In this paper, we classify...

Pre-Design Planning with Intelligent Project Development Brochure (IPDB) System
The functional design criteria and other technical requirements are to be established during the pre-design planning stage of a project. At this pre-design stage, the formulation of the...

Knolle Magnetrans: A Magnetically Levitated Train System
New permanent magnet materials can now withstand repulsion indefinitely without loss of magnetism. Vehicular magnetic levitation occurs when a track and the undersides of vehicles thereon...

T. L. James Marine Group Beach Nourishment Projects
To complete the referred to projects as used the highly maneuverable, 1,300 cubic-yard-capacity hopper dredges ATCHAFALAYA and MERMENTAU, both of which are self-propelled, split-hopper,...

From Planning to Construction in Coastal Louisiana (With a Cast of Thousands)
In light of the 25 square mile loss of coastal wetlands in Louisiana, the Coastal Wetlands Planning, Protection, and Restoration Act mandates that a interagency Task Force develop a comprehensive...
