Successful Behavioral Devices for Fish Protection
Since 1987, the Electric Power Research Institute (EPRI) has been sponsoring studies of behavioral barrier devices for protecting fish at hydroelectric facilities. Primary emphasis has...
Training the Waste Watchers
Whether an engineer is going to work at a Superfund site himself, or if his firm will be doing cleanup work at the site, that engineer will want to take the 40 hour training course as...
Segmental Tunnel Lining Meets `Buy American'
Segmental concrete tunnel lining is the other innovation proven during construction of the Washington Metropolitan Area Transit Authority (`wmata'). Although `wmata's'...
The Cost of Quality: A Management Tool
In design and construction of engineered facilities, the cost of quality is a major cost item; perhaps exceeding one fourth the total installed project cost. A simple, flexible Quality...
Potential Misuse of Construction Scheduling Software
The advent of microcomputers, coupled together with the development of many easy to use and economical scheduling packages, has placed a very powerful tool in the hands of construction...
Opportunities for Innovation in Construction Equipment and Methods
New applications and other significant driving forces indicate a strong opportunity for innovation in construction equipment and methods. Investigations of other industries provide a rich...
Automated Position and Control Systems Using Lasers and Electromagnetic Signals
Positioning is a crucial area in the successful integration of CAD data into the construction process. This paper looks at several areas of positioning using lasers and electromagnetic...
High Speed Multi-Link Automated Control
A new manipulator control technique is being investigated with potential for improving equipment life and productivity without requiring more operator training. It can retrofit to multi-link...
Real-time Monitoring of Heavy Equipment in Open Pit Mines
This paper reports on a system with local intelligence to interpret on-board signals. Existing sensors, pressure switches, warning lights, relays, and on-board monitoring systems provide...
Who Pays for the Unexpected in Construction?A Contractor's Viewpoint
There are two categories of 'unexpected' conditions inherent in a construction contract. The first are what might be regarded as normal construction risk such...
Refurbishment and Modernization of Hydro Plants
In order to assemble experiences, settle and systematize the problems connected with rehabilitating and redeveloping hydro power plants and to work out proposals a project titled 'Refurbishment...
Selection of Jim Falls Turbine Generators
The selection of the unit configuration for the Northern States Power Company's Jim Falls Hydro Redevelopment Project was based on an extensive evaluation of various turbine...
Equipment Selection and Site Optimization Based on Energy Considerations
Most new hydro plants contribute little or nothing to overall system capacity. Therefore, traditional evaluation techniques based on dollars per installed kilowatt have no relevance when...
Multisite Hydrocomplex Optimization
A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen...
Murray Hydro Project?Structural Design
This paper will summarize design criteria, parameters, methods of analysis, and other relevant data that were used in the design process of the structural features of the Murray powerhouse...
Early Detection of Rotor Cracks?Monitoring & Methodology
This paper describes a diagnostic method for the early detection of shaft cracks on rotating machines. The method is based on interpretation of the lateral synchronous (1x) and twice per...
Variable Speed Generators in Hydro Applications
This paper discusses the investigation of the doubly-fed variable speed machine as a potential candidate to convert a varying input speed to a constant frequency, constant voltage output....
Characteristics of the Roesel Machine Used for Small Scale Hydro/Wind or Sea Wave Electric Power Generation and Storage
