Water Supply Uncertainties with Federal Permitting
Providing water in a semiarid region has historically been one of the most important responsibilities of government. This task was made more difficult by the uncertainties involved with...

Development of a Prioritization Tool for Multimedia Enforcement
This paper describes a decision support system developed for the Environmental Protection Agency that assists their staff in the prioritization of resources for the enforcement of multi-media...

Regional Water Supply Development in the SWFWMD
Regional water supply authorities have been formed within the Southwest Florida Water Management District in an effort to meet growing water demands of a rapidly expanding population....

Regional Water-Supply Development and CWA Section 404
Regional water-supply development is generally promoted because of potential cost savings and improved system management, but regionalization may also provide an opportunity to reduce...

A Logical Variable Approach to Water Supply Reliability
The calculation of the reliability that water will be available at a demand point in a distribution network is complicated by the redundancy of paths from the source to the point. The...

Public Involvement: Key to Stormwater Programs
The ultimate success of a stormwater program often depends upon the support of concerned citizens. Interaction between stormwater managers and the public is especially important in small...

Improved Finite Element Modeling with Q-MESH and PARA_?LIB Parallel Processing
Distributed-memory multiprocessing, based on the Inmos transputer, provides orders-of-magnitude reductions in computing time at the lowest cost per MFLOPS. The PARA_LIB runtime library...

AI Development Environment for the Maintenance of Existing Buildings
A specific structural typology is considered with a deep expertise available on the subject. The 'state of health' of a single building is assessed by an expert...

COFDEX: Composite Floor Design Expert
A knowledge-based system, called COFDEX, is presented for integrated minimum cost or minimum weight design of composite floors in multistory buildings. Developed in the expert system programming...

A Neural Network Environment for Intelligent CAD
A framework is presented for development of an environment for creating intelligent systems for computer-aided design of structures by integrating neural network models of learning and...

Sensitivity Analysis for the Numerical Evaluation of Wind Effects on Buildings
The paper describes the sensitivity analysis carried out in the computational evaluation of wind effects on buildings by using a computer code named TWIST - Turbulent WInd Simulation Techniques....

Computation of Wind Flow Around a Building
A numerical investigation of wind flow around a three-dimensional building is presented by solving weakly compressible flow equations, together with Smogrinsky's subgrid-scale...

Optical Performance Predictions and Testing of a Composite Reflector
This paper describes the structural analysis and the experimental performance evaluation of advanced composite mirror designs for future NASA astrophysics missions. An interdisciplinary...

Vibration Suppression Through Liquid Oscillations
A passive liquid-motivated control system is proposed to suppress and reduce the lateral drift of high-rise buildings. The vibration reduction mechanism relies on liquid motion to alter...

Synthesis of Lateral Structural Bracing with Active Tendons
The idea of combining X bracing, viscoelastic dampers, and active tendons in a structure which has been optimized for gravity loads is presented. It is shown that reduction of the structure's...

Recapturing Boston's Heritage
Structural upgrading of Boston's Old State House and Faneuil Hall is part of an extensive restoration project undertaken by the National Park Service at a cost of $10.6 million...

State Legislative Concerns Relative to Federal Hazardous Materials Transportation Regulation
States have increasingly asserted their authority to regulate hazardous materials transportation, in the face of inadequate and declining federal efforts. Areas of state interest include...

Hazardous Materials Data: A Federal Perspective
This paper discusses the evolution and current status of the Hazardous Materials Incident Report System (HMIRS) maintained by the Research and Special Programs Administration (RSPA) of...

Recent Developments in Hardware and Data Processing for Telemonitoring Various Structures
Some of the latest automated centralized monitoring systems being used by civil engineers in France shall be reviewed, along with details of the benefits from this approach and some of...

Up and Down Construction of a 17-Story Building
The One Westwood Building is located on a small site in the Westwood district of Los Angeles. Construction of the 17-story building with 8 levels of subterranean parking was complicated...
