The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...
Black Holes
For many years, scientists have searched the skies for black holes; stars even more massive than white dwarves. As of yet, there have been no 100% sure sightings. Since they do not emit...
Space Power Systems?Radiation: Energy Conversion
Pair production is a way to change a photon, a gamma particle, into matter or energy. It is found that if a photon of energy greater than 1.02 MeV strikes a foil containing a large number...
Benefits of Radioisotope Thermoelectric Generators
Since the 1960's the United States has had the capability to reach beyond the planet Earth with the aid of satellites and interplanetary space probes. As probes such as the...
Renovating the Riverside Water Plant?A Case Study
In 1986, the City of Waco, Texas began construction of the first of four projects designed to renovate the Riverside Water Treatment Plant. The water treatment plant was originally constructed...
The Use of Submersible ROVs for the Inspection and Repair of Water Conveyance Tunnels
At Virginia Power's Bath County Pumped Storage Station, robotic technology was pioneered through the development of a purpose-built Remotely Operated Vehicle (ROV) to gain...
Optimal Control Strategies for Water Distribution Systems
The overall operation problem becomes one of determining which pumps to run and when to run them so that electrical unit costs and electrical demand charges are minimized while at the...
A Methodology for Optimal Control of Pump Stations
Pumping water to utility customers is an expensive service which consumes large amounts of energy. Most approaches to date require simplifications and assumptions for the specific system...
Probabilistic Analysis of Maintenance Options
Maintenance usually means service disruption, repair cost and loss of production. This is especially true for structures or components which provide basic infrastructure services, such...
Realities of Infrastructure Financing
Federal financing of water supply and water treatment projects will continue to decrease as capital demands continue to increase for expansion of water supply, to replace aging systems,...
Recognizing Institutional Barriers in Regionalizing Water Supply Infrastructure
The Northern Colorado Water Conservancy District (District) is conducting a study to determine the feasibility of implementing expanded regional cooperation for future municipal and industrial...
Financing Small Water Supply Projects in Colorado
In order to meet the water supply needs of Colorado communities and the requirements of the Safe Drinking Water Act of 1986, the Colorado Water Resources and Power Development Authority...
Capital Improvements Financing and Planning After a Natural Disaster
The Pima County Wastewater Department (PCWWMD) provides collection, treatment and disposal of wastewater in metropolitan Tucson, Arizona, and various outlying areas. In October 1983, severe...
Developing a Privately Owned Utility in Florida: Financing and Cash Flow
Private developers of a 5,000-acre master-planned community in Sarasota, Florida, were required to provide their own wastewater treatment plants as a condition for obtaining permits. After...
Expert System for Budget Preparation and Optimal Operation of an Interconnected Power Utility
Manitoba Hydro operates a complex system of 13 reservoirs, 2 thermal and 13 hydro generating stations, and 9 interconnections to other neighbouring power utilities. The Energy Management...
Optimal Real-Time Operation of Te-Chi Reservoir
An optimization model for the 10-day operation of Te-Chi Reservoir in central Taiwan is developed. The inflow to the reservoir is forecasted by an ARX model with a Kalman Filter updating...
Estimating the Energy Rate Function for Hydro Power Production Optimization
Operations planning at Manitoba Hydro is aided by using the Energy Management and Maintenance Analysis (EMMA) computer program. EMMA is a Linear Programming (LP) based model with the objective...
The Development of Lake Granbury SWATS Regional Electrodialysis Reversal Demineralizer Treatment Plant
Due to high population growth and rapidly declining groundwater levels, the Brazos River Authority of Texas initiated a regional study to evaluate existing and potential surface water...
Managing Two Lakes with Significant Tailwater Fisheries
Norfork and Bull Shoals Dams on the White River in Arkansas were constructed in 1944 and 1951, respectively. The authorized purposes were for flood control, hydropower generation, and...
Ute Mountain Ute Indian Water Rights Settlement of 1988
