Crop Irrigation Requirement Model for Utah
Crop irrigation requirements vary greatly across Utah's wide range of climatic conditions. About 40 electronic weather stations have been established in areas representing...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Probabilistic Approach to Maintenance Scheduling
Maintenance has the purpose of prolonging the working life of equipment and of sustaining expected levels of performance and reliability. If equipment deterioration is construed as a probabilistic...
Probabilistic Maintenance Opportunities
The Bureau of Reclamation has instituted a number of operation and maintenance oversight activities to ensure that Reclamation and water-user operated projects are operated and maintained...
Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...
Rigid-Lid Flow Calculations with MacCormack's Method
R.W. MacCormack's Method is employed for the calculation of subcritical flow in shallow water. The flow is assumed to be incompressible with rigid boundaries above and below,...
Terrestrial Trends for Building Technology in North America
This paper discusses new building technologies that will develop in the early 1990's to become significant technologies by the mid 1990's. The perspective is...
Candor Chasma Camp
This paper proposes a camp at Mars, in the Coprates region of the Valles Marineris rift, just below the equator on Candor Mensa 6�-12'S, 73�-30'W. Beginning at...
Homesteading Mars
The author gives serious study to setting up a permanent Martian base during the first or second manned Mars mission. The savings of fuel and equipment for the return trips might pay for...
The Role of a Mobile Transporter in Large Space Structures Assembly and Maintenance
Large space structures require a vehicle to support assembly, operations, and maintenance. These vehicles may be designed for specific tasks or for general use throughout the life of the...
Survey of Soviet Space Welding Technology Development
Soviet engineers clearly recognize the potential value of welding for maintenance, repair, and fabrication of structures in space. The development of this technology has followed a steady...
The Role of Welding in Space Maintenance and Repair
The nature of future space missions will result in increased incidence of degradation, damage, and wear of critical or expensive hardware. In many terrestrial applications welding provides...
Pacific Space Port
The concept of the Pacific Space Center advocated by Mr. Tetuso Kondo (member of the House of Representatives, former Director General of the Economic Planning Agency) and Dr. Tatsuo Yamanaka...
Strategy for Design and Construction of Lunar Facilities
This paper summarizes the results of a qualitative investigation to identify methods for design and construction of near-term lunar facilities. It is judged that to accomplish such construction...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
The Human Element in Space: Lessons from Antarctica
The human ability to adapt and perform in an extreme environment during periods of prolonged isolation is influenced by a number of social, cultural, and psychological parameters. These...
A Space Station Millimeter Facility
The design and use of a large millimeter telescope for construction on the planned Space Station (a Space Station Millimeter Facility, SSMF) are described. Such a facility would have manifold...
Nature's Solutions to Space Insulation
Humans working or living in the harsh environment in space must be protected from temperature extremes. Any effective insulating system must be able to withstand a wide range of temperatures....
Structural Art in the Lunar Environment
Building structures will be a necessary part of extending our presence on the moon. In designing and building these structures, aesthetic value will play a prominent role. History shows...
CADD, The Integrated Data Base (IDB), and Engineering, Construction and Operations (EC&O) in Space
