Establishing a Geographic Information System
The ultimate test of an advancement in civil engineering is the successful integration of aspects of the advance into the general engineering community. Success stories in this area include...
Corps of Engineers Water Control Data Systems for the 90's
Corps of Engineers water control data systems encompass all of the instruments, equipment, computers, and software used to collect and use environmental data in real-time water control...
A Prototype Distributed Processing System Water Control Data Processing at Tulsa District U.S. Army Corps of Engineers
The Tulsa District, Corps of Engineers operates 50 multi-purpose reservoirs controlling runoff from all or parts of 7 states. These reservoirs are operated for flood control, water supply,...
Water Supply Impact Analysis of Proposed Water Quality Control Plan for Salinity for San Francisco Bay and Sacramento-San Joaquin Delta Estuary
This paper presents the procedures and techniques employed as part of the Bay-Delta proceedings to evaluate the water supply impacts of various proposed flow and water quality objectives...
Summary of Stormwater Quality Management Practices
The control of water quality in urban runoff is in its technical infancy. Never-the-less Water Quality Act of 1987 states that stormwater pollution must be reduced to the maximum extent...
Automatic Control of a Sewage Interceptor
This paper presents a control system for the automatic operation of a sewage intercepter with control gates to reduce sewage discharge to the receiving waters. One of the issues of the...
Total Quality Management
Total Quality Management (TQM) is an organizational management approach that is receiving increasing attention in a wide variety of organizations, including the Ford Motor Company, General...
The Hydrology of Urban Runoff Quality Management
Recent regulatory requirements to reduce pollutant discharges from municipal storm sewer systems have intensified the need for approaches to developing design parameters, such as the selection...
Adaptive Control of Groundwater Hydraulics
Adaptive control has been extensively applied in industrial settings for the control of unknowns systems, systems with uncertainty in the parameters. The approach is recursive, the response...
Case Studies on the Use of Semi-Standalone Control Loops for the Management of Regional Public Water Supply
The West Coast Regional Water Supply Authority is charged with the operation and management of the public water supply that serves over 1 million people in the Tampa Bay Area of Florida....
A Control Method for On-Demand Operation of Open-Channel Flow
This paper proposes a control system for the automatic operation of an open channel having upstream and downstream gates. The main issue is the use of a discrete-time algorithm which computes,...
A Comparison of Two Large Scale NLP Strategies for Determining Optimal Pump Station Controls
To solve the general nonlinear problem which is not simplified using the uniform spatial demand patterns, a two-level hierarchial scheme has been identified. The purpose of this decomposition...
Stormwater Quality Issues for Jefferson Parish
Jefferson Parish has a unique set obstacles to overcome in the operation of the drainage system. Situated in a coastal area and surrounded by water, the area has been developed through...
Design of a Neural Network Power Grasp Controller
An overview of research on the development of an artificial neural network controller used to implement power grasping on the DIGITS Grasping System is presented. The DIGITS System, under...
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...
Time-Delayed Control of Nondispersive Continuous Systems
This paper deals with the noncollocated, time-delayed active point control of continuous systems. It considers systems of finite spatial extent which can be modelled by the undamped wave...
Optimal Control Configuration for Active Control of Structural Vibrations
An active tendon control mechanism is used to control the vibrations of a bridge-like structure. A single control force controls three modes of vibrations. Special attention is paid to...
Input-Output Discrete-Time Control of Structures
This paper outlines an approach for active control of structures based on the identification of a linear difference equation to describe the control loop and the design of a discrete-time...
Distant Eyes
A remotely operated vehicle is a miniature unmanned submersible that contains lights, a video camera, other instrumentation, and motor thrusters to move it through the water. The operator,...
Risk Perception and Policy Preferences of Fire Chiefs: A Survey of Hazardous Materials Issues
This paper presents the results of a survey of Connecticut fire chiefs and discusses how their perceptions of risk affect their attitudes towards risk preparedness and risk management...
