CAD/CAM: Reverse Engineering Applications
The reproduction of parts for which drawings or CAD files are not available has always caused engineering effort to be expended in a non-routine manner. The need for such a reverse engineering...

Using a CAM System for Generating Potential Solutions in Machining Processes
This paper presents a software package which was designed to generate potential solutions for producing specific machine shapes as an application of a Computer Aided Manufacturing (CAM)...

Teaching Computer Numerical Control of Manufacturing Processes
A series of part programming problems assigned to the students are described. These assignments progressively expose the students to manual programming, computer assisted part programming...

A Minimal Input Computer Aided Manufacturing Program for Personal Computers
The author presents here an algorithm developed in Pascal for an integrated two and a half dimensional CAD/CAM system. The geometry and the tool paths are defined simultaneously, thereby...

POU/POE Devices: Availability, Performance, and Cost
In order to gather and summarize information and data on point of use/point of entry (POU/POE) devices, a committee was established by the Environmental Engineering Division of the American...

Use of POE/POU Technology at US Army Installations
A wide spectrum of adverse water quality characteristics has been experienced at US Army installations throughout the country. These characteristics, both interim and long-term in nature,...

Digester Gas Resource Recovery at Phoenix, Arizona
Until July 1986, the digester gas produced at this 150 million gallon per day facility, in excess of what was utilized for heating anaerobic digesters was flared. In 1983, a feasibility...

Chemigation Equipment for Protecting Water Quality
Concerns for protecting groundwater quality have brought forth some strict EPA regulations on equipment required for injecting pesticides into irrigation systems. These chemigation equipment...

Computerized Resource Planning for the Central Valley Project, California
The Central Valley Project (CVP) consists of nine reservoirs and ten powerplants owned and operated by the United States Government. On an average water year basis, the CVP, with a maximum...

Computer Simulation of CVP Power Production for Integration With PG&E's Power System
The Central Valley Project (CVP) has an installed hydropower capacity of over 1800 MW. The project facilities and its preference power customers lie dispersed within the service territory...

A Microcomputer Model for Integrated Analysis of Peaking Hydro in a Thermal System
An integrated approach to simulation of a hydro system called HYDROMOD has been developed and used to place a value on additional energy-limited peaking hydro capacity added to a major...

Hydropower Stochastic Forecasting and Optimization
A microcomputer package was implemented to support real-time decisions for weekly and month-end water management at an industrial complex in the mountains of British Columbia. The rolling...

History of the Federal Interagency Sedimentation Project
Since 1939, the date of the Project's inception, the team has operated under the direction of two lead agencies - the U.S. Geological Survey and U.S. Army Corps of Engineers....

The Hydro Business: 1990 and Beyond
During the last ten years, hydroelectric generation received more and more attention as a source of reliable and economical electricity. Since the first WATERPOWER conference, the industry...

Status of Hydropower Development at Corps of Engineers Dams
The Corps of Engineers is the largest single supplier of hydroelectric power in the United States with 74 projects and an installed capacity of 20,839 MW. In addition, 33 Corps projects...

The Development and Writing of the ASCE/EPRI Hydroelectric Guidelines
In the Spring of 1989, the American Society of Civil Engineers (ASCE) and the Electric Power Research Institute (EPRI) jointly published their Civil Engineering Guidelines for Planning...

Project Evaluation?Don't Miss the Boat
The hydroelectric developer is faced with many decisions during the evaluation stage. These include determining the size of the project, financial analysis to be used, type and number...

Hydropower Development under the Utility Concept of Least Cost Utility Planning
The impetus behind 'Least Cost Utility Planning' (LCUP) is that if new generation or purchased power could be deferred, the resultant savings could be used to...

Determining Hydro Project Dependable Capacity
Traditional techniques for estimating a hydro project's dependable capacity are of limited value when evaluating a hydro project in a thermal-based power system. For such...
