Lessons Learned from First Impulse Turbine Installation in the U.S. Mining Industry
The paper discusses a research study to recover energy from service or cooling water brought into deep mines. The test site was the Luck Friday Mine, owned and operated by the Hecla Mining...
Hydro Power Intake Design?Criteria and Experience
This paper briefly addresses parameters to be considered in hydro power intake designs. Included are design approaches and criteria, specific examples, and applicable references. Concerns...
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...
Computer Management Concepts for Student Engineering
This paper presents many of the principles and concepts being taught to engineers of the future concerning their use of computer related activities. For example, from the cost/risk/benefit...
Microcomputer Software Support at the State Level
This paper describes a case where the organizational approach to microcomputer control was taken and contrasts the results with optimal individual systems within the group. In this context,...
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...
Database Systems in Transit Management
This paper describes the use of microcomputer database managers by transit operators. The findings are based on a survey of transit operations of various sizes in the southwest U. S. in...
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...
Surveying's New Promise: Centimeters from Space
One centimeter accuracy at far less cost than surveying by traditional methods is promised by the Global Positioning System (GPS). Signals from NAVSTAR satellites are received by two or...
Trends in Small Computer Utilization
In an effort to determine the extent to which micro and minicomputers have been successfully implemented by construction contractors, the authors compiled a comprehensive questionnaire...
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...
Rehab: More Art than Science
A survey of structural/civil engineers revealed that low fees are the major problem in structural rehabilitation work. Other concerns are unforseen conditions, inadequate investigation,...
