Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
Laplace Valve Stroking for Complex Piping Systems
LaPlace valve stroking to control water hammer is applied in complex piping systems with friction and without friction. Two types of system are analyzed. The law of operation of the valves...
Keeping Up With Computers
As computer hardware and software continue to grow in power and complexity, with new advances announced every day, many engineers wonder how to keep up with the rapid pace of change. When...
Poland Gets Moving
Poland's transportation network is a victim of two world wars, foreign domination, and neglected maintenance, but there are ambitious plans to rebuild the road and rail systems....
Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD)
This publication, Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD), (ASCE 15-93), is applicable to buried concrete precast pipe intended...
Upgrading Dubai's Sewers
The sewerage system serving the city of Dubai in the United Arab Emirates, is plagued with odor and corrosion problems. System elements were deteriorating and failure rates were increasing....
America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...
Offshore Rescue
Restoration of wastewater ocean outfalls can be difficult, dangerous and environmentally challenging. Two recent projects, however, serve as examples of innovative outfall rehab. The first...

Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...
Network Management Using GIS
This paper is concerned with the opportunities that arise from combining digital highway networks, relational databases, GIS technology, specialist application software, and workstation...
Florida's New Toll Facilities Model
Florida's Turnpike provides a system of user-financed limited access toll highways meeting important transportation needs in the State of Florida, while protecting the interests of its...
Development of Self-Organizing Traffic Control System Using Neural Network Model
This paper is concerned with developing a self-organizing traffic control system using a neural network model, a multilayer network model. The neural network inputs the control variables,...
The Traffic Operations Control Center Simulator
As a part of a national effort to improve the operatinal efficiency of the highway network, the California Department of Transportation (CALTRANS) is developing and implementing general...
A Highway Maintenance Operation Database
This paper presents the major findings of a study to develop a system design for the implementation of an electronic network which uses personal computers in local highway maintenance...
CADD Applications in Transportation: Beyond Highway Design
Computer Aided Design and Drafting (CADD) software have become very prominent in the design of transportation facilities. There are currently a number of third party packages that operate...
Trip Generation Analysis by Artificial Neural Networks
A new approach for conducting trip generation analysis based on the concepts of artificial neural networks is presented in this paper. First, a brief introduction to the concepts of artificial...
Fast Foundation for Soft Clay
This article describes the detailed foundation work and high-capacity piling design for a flue gas desulfurization (FGD) retrofit system for the Lambton Generation Station in Ontario,...
Neural Networks in Structural Control
Let the response of a simple two-story frame to a stochastic dynamic excitation be controlled by activating suitable actuators. A neural network is trained to recognize, from the measurement...
Ductility Analysis of Overload and Settlement
The concept of sufficient ductility to avoid premature or brittle failures is gaining wide acceptance in structural engineering and is an important aspect in mitigating the consequences...
