Guideway and Conductor Rail Heating for a Winter Environment
The power and signal conducting rails are maintained using self-limiting heat trace cable in combination with an inherently protected rail. The cable's high inrush power along...
Insulative Lightweight Concrete for Building Walls
Research is currently being conducted to develop a portland cement concrete for use in low-rise building walls that will combine the structural, thermal insulating, and heat storage capacity...
Energy Forecasting Techniques: An Overview
This paper provides an overview of the primary forecasting techniques employed by electric and natural gas utilities to predict energy consumption and demand. Although the techniques discussed...
POSIT?An Interactive Timing Optimization Program
A window-oriented, microcomputer-based signal optimization program called POSIT (Program for Optimizing Signalized Intersection Timing) has been developed that provides traffic engineers...
Engineering with Spreadsheets
With an electronic spreadsheet, the geotechnical engineer has a powerful tool for solving routine engineering problems. The ability of the electronic spreadsheet to use the calculus of...
Second-Guessing the Engineer
The relationships between utilities and the bodies that regulate them have changed drastically in the past few years. No longer can any costs associated with the construction of new power...
Distillery Wastes Treated and Recovered Energy Saves $1 Million/Yr
The waste treatment and energy recovery for the world's largest rum distillery (Bacardi Corp., San Juan, Puerto Rico) uses an aerobic digestion to treat distillery wastes...
Base Isolation Concepts for Seismic Bridge Retrofit
Failures in past earthquakes have indicated three major problem areas with existing bridges. The first is the vulnerability of existing rocker and roller type bearings and this is coupled...
Refuse Recycling
The refuse recycling plant at Columbus, Ohio, is a pioneer in burning as fuel a combination of refuse and coal. This hybrid fuel has advantages over burning either alone. One winter in...
Coal Terminal
The Charleston Shipyard River Coal Terminal was constructed by converting a port-side chemical plant at a third of the cost of equivalent major coal terminals. A staged program for the...
Energy Recovery
In Albany, N.Y. the state and city cooperated in designing and building a refuse-into-steam energy plant that has several unique features. In most such facilities, the entire plant is...
Safety Investigations of Existing Spent Fuel Storage Structures for Increased Spent Fuel Storage Capacity
Delays in the solution of disposal problems continue to create the need for additional on-site spent fuel storage capacity at commercial nuclear power generating facilities. Rod consolidation...
Database Management
Computer aided design systems have found widespread acceptance from Engineering companies as drafting/detailing/drawing tools. While this has brought a dramatic productivity improvement...
Wetlands Development in Moderate Wave-Energy Climates
For the last three years springs of Spartina alterniflora have been planted on portions of Theodore Island, a dredged material island in Mobile Bay, Alabama. The purpose of the planting...
Dredging for a new Port - Puerto Bolivar, Colombia
A major coal export terminal at Bahia Portete, Colombia, is being developed as part of the Cerrejon Coal Project - North Zone, where one of the world's largest coal mines...
Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...
Modeling Effects of Toxicants on Aquatic Systems
Potential effects of chemicals on biomass production in aquatic systems are extrapolated from laboratory toxicological assays. The extrapolation requires that the effect of acute toxicity...
Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...
Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...
A Three Dimensional Hydraulic Jump
A study is conducted to define the three-dimensional hydraulic jump that occurs in a rectangular channel downstream of a rectangular contracted sluice gate. A sequent depth ratio equation...
