The Economic Cost of Stocking Catchable Rainbow Trout
States annually stock about 20 million pounds of catchable trout in public waters. Complete information on cost is essential to help wildlife agencies make operating and planning decisions....
Refinement of Cost Estimates with Artificial Neural Nets
An estimate should be refined for undefined items. Usually, contingency is added to cover any inadequacies in estimate basis definition and inadequacies in estimating methods and data....

Engineering: Environmental vs. Developmental Goals
The 1992 winner of the Daniel W. Mead Student Paper competition explores the potential conflict for engineers, between environmental and developmental goals. Noting a dictionary definition...
Modal Failure Probability and System Performance
It is pointed out that the modal failure probability, i.e., the probability that a structure fails in a particular mode, cannot be uniquely defined under the time-invariant framework....
What is Optimization?
Basic concepts of optimization are described using design of a plate girder as an example. First, a way to formulate the problem as an optimization problem is presented. Then basic terminologies...
What Do You Mean by That?
The engineering and construction profession, like any other, has its own buzzwords and jargon. But as terms become ingrained in the profession's lexicon, they take on different...
CAD Instruction for Civil Engineering Students
Computer graphics and computer-aided drafting (CAD), as well as manual graphics and descriptive geometry, are successfully taught to civil engineering sophomores. The paper presents the...
High Speed Ground Transportation: Some Historical Perspectives
The definition of `high speed' ground transportation is relative to the transportation technology of a period. Thus it might be argued that high speed ground transportation began early...
Noise from High Speed Maglev Transportation Systems
Noise levels from magnetically levitated trains (maglev) at very high speed may be high enough to cause severe environmental noise impact in residential areas, even without physical contact...
Injury Determination and Quantification
Several different approaches for injury determination and quantification are discussed within the framework of the natural resource damage assessment process. The basic concepts and terminology...
AVL's Future Holds Little Value without Integrated Data Communications for Total Mobile Resource Management
The future of automatic vehicle location (AVL) lies in broadening its definition for greater market acceptance and applicability. AVL by itself is for limited utility. To solve real-world...
Alluvial Fan: Subset Definitions
The Flood Control District of Maricopa County, Arizona recently completed a study whose goal was to identify and describe four alluvial fans for instrumentation and long-term monitoring....
Environmental Impact Analysis of Coastal Projects
It is fairly routine to describe the range of impacts that might occur as a result of a proposed improvement, but problems and controversy often accompany attempts to answer the more pressing...
Extraterrestrial Resources: A Perspective from Terrestrial Economic Geology
Terrestrial mining experience indicates that the overwhelming criterion of a potentially economic deposit is its recoverable concentration of the desired mineral or element. These criteria...
Minneapolis/St. Paul International (MSP) Part 150 Implementation Design Overview
In February 1991, Matropolitan Airports Commission (MAC) selected the consulting team of Aviation Planning Inc., Wyle LAboratories Inc. and the Center for Energy and the Urban Environment...
Laboratory Tests of Modal Emissions and Off-Cycle Corrections to FTP-75
The modeling of emissions from on-road mobile sources is an on-going process. Two broad topics which are currently under study are the evaluation of driving cycles and the development...
Technology Transfer for Projects in South America
Engineering services were provided for three projects in South America. One project was located in the Pampa Region of Argentina and two others in northern Brazil. The projects were: 1)...
Meteorological Aspects of Drought
This is an overview paper discussing meteorological aspects of drought, and it is part of the report of the Task Committee on Water Management During Droughts. Several drought definitions...
