Fluid Behavior Considerations for Waste Management in Low-Gravity Environments
Design of waste recycling systems for spacecraft requires a knowledge of fluid behavior in microgravity. As gravity is reduced, phenomena usually ignored in the One-G environment of earth...
Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....
Hedratecture and Artificial Gravity
There is a need, according to the National Commission On Space, to develop three critical space facilities: A Space Base, A Variable-Gravity Research Facility, and a Lunar Surface Outpost....
Planning Model for Sewer System Rehabilitation
A probabilistic model is developed to simulate long-term variation in the structural condition of wastewater collection systems. The effects of both deterioration and rehabilitation can...
Probabilistic Basis for Managing Maintenance
The paper discusses a procedure based on component failure probabilities, consequences of failure, and risk associated with loss of system. Aging effect of structures and equipment on...
Models for Optimal Maintenance of Hydraulic Structures
Corrective maintenance includes the unscheduled repairs required to return a structure from a failed state to an operating or available state. Corrective maintenance is determined by the...
Reliability Estimation for Vertical Lift Gate at Emsworth Dam
The lift gates are composed of two horizontal trusses, two vertical girders, seven diaphragms, and two end frames. A critical element in the structural integrity of the lift gate is a...
Economic Assessment of Infrastructural Development for the Gurara River in Nigeria
Based on the preliminary designs of the hydraulic structures for the proposed Gurara river water development project in Nigeria, an economic feasibility analysis is presented. The cost...
Considerations for a Multiple-Use Stormwater Detention Facility
A 60-year-old neighborhood provides the unusual setting for the City of Tulsa's Turner Park-Will Rogers High School Stormwater Detention Facility. The 20-acre site is located...
Identification of Aquifer Parameters in Confined Groundwater Flow
The logarithm of the aquifer properties, log transmissivity (log T) and log storativity (log S), are regarded as realizations of stochastic processes whose estimates are required. The...
Flownets by Computer Graphics
A new method of drawing flownets for determining seepage losses in earth dams is developed. The flow and equipotential lines are drawn by modifying W. Kinzelbagh's method....
Application of Interactive Videodisc for Work Zone Traffic Control Training
This paper describes the development of the Interactive Videodisc Training (IVT) system and a training course on work zone traffic control. The IVT system uses a microcomputer-controlled...
Tri-County Based Travel Demand Forecasting Analyses in the Tampa Bay Area, State of Florida
This paper describes the application of the micro-computer compatible Florida Standard Urban Transportation Modeling Structure (Micro-FSUTMS) to estimate traffic volume for the purpose...
A Comparative Analysis of Microcomputer and Mainframe Computer Based Modeling Systems
This paper presents a comparative analyses of the Microcomputer Compatible Florida Standard Urban Transportation Modeling Structure (Micro-FSUTMS) performance with its UTPS mainframe computer-based...
A Future for UTPS on Microcomputers
The software and hardware support for Micro-UTPS is in a state of transition. IBM's development of the PS/370 gives mainframe power and performance to microcomputers and Micro-UTPS....
TRAF-EDIT: An Interactive Data Editor for the TRAF Simulation System
This paper describes TRAF-EDIT, an interactive data entry/editing program for the TRAF simulation system. TRAF-EDIT will provide the user with the capability of creating an input data...
A Microcomputer Based Pavement Design Program
This paper describes a newly developed pavement design program. The performance of a number of pavement structures are projected over the analysis period. Structurally adequate designs...
A Microcomputer Methodology for Parsimoniously Structuring a Set of Activities
The paper develops a systematic methodology to aid in the identification and rapid structuring of a system of activities. In essence, the user is asked to supply only the names of the...
Flow Separation of Currents in Shallow Water
Flow separation of currents in shallow coastal areas is investigated using a boundary layer model for two-dimensional (depth-averaged) tidal flow past an elliptic headland. If the shoaling...
Calibration of a Transport Model Using Halocarbons
A field study was conducted during April 1987 in which the concentrations of volatile halocarbon tracers, discharged from two existing outfalls, were measured throughout Boston Harbor...
