DYCAM: A Computer Aided Engineering Tool for Space Construction Planning
Planning and management of construction activities in space have not received sufficient attention up to the present. Space Station Freedom, a number of large platforms and extraterrestrial...

The Selection of Constructors for Space Construction
The process of space construction is defined by the construction goal and by the construction system selected to accomplish that goal. The goal provides the tasks that must be executed,...

A Language Model for Space Construction Control
The optimal construction system for many space construction projects is a mixed construction ensemble. Such an ensemble consists of humans, robots with varying degrees of teleoperation...

Level of Recycling Effectiveness
The Level Of Recycling Effectiveness (LORE) scale is presented. It is a conceptual framework for evaluating recycling and other alternative strategies of meeting needs in space activities....

Encouraging Students to Enter Math, Science, and Space-related Fields
Most people agree that education is the key to technological superiority, that our current state of education is prohibiting the United States from being as competitive as it once was,...

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...

Urban Drainage Pipe Systems: Failure Diagnosis and Rehabilitation Planning
A Task Committee on Failure Diagnosis and Rehabilitation of Urban Drainage Infrastructure has been organized by the Urban Water Resorces Committee of the Water Resourcs Planning and Management...

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...

Funding Inland Navigation Infrastructure
