Columbus Generic Element Management Concept
The concept for largely autonomous onboard management of the ESA Columbus project elements relies on the automation of operational procedures. Reconfigurable items are commanded in sequence...
Normal Accidents and Logistics in Space Operations
Unpredictable systemic accidents, normal accidents, will occur in highly-complex large-scale space systems. To mitigate the catastrophic consequences of normal accidents, containment engineering...
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...
A Cost Study of Concrete Production on the Moon
In proposing and evaluating a construction system for a lunar base, the question of cost would be the most important one. Although it is not possible to conduct a detailed cost study at...
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....
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...
Mission to Planet Earth: The Quest to Save the Environment
The Mission to Planet Earth is a program designed to look at the earth as an integrated system. It is an internationally supported project. It was conceived because the current methods...
New Technologies for Unmanned Space Exploration
There could be no better time than now for the development and implementation of new technologies such as V.L.S.I. and optoeraseable storage. Creative inventions from new mathematical...
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...
Alternatives for the U.S. Manned Space Program
There are a number of directions the U.S. space program could take. Should a space station be built? Should a lunar outpost be constructed? Should the U.S. plan a manned trip to Mars?...
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...
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...
Review of the Design, Construction, and Operation of the Lake Carolyn Flood Control Pump Station
A review of the design, construction, and initial operation of the Lake Carolyn Flood Control Pump Station in Irving, Texas is presented. Staged water resource development design concepts...
A Microcomputer Program for Roadway Lighting Design
LUMSIM is a knowledge-based design program that uses operator input data and design criteria to select the most economical lighting system. The initial input parameters include pavement...
CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
The paper reviews the experience of the Chicago Transit Authority's partnerships with the private sector. The funding, space, design, construction and operation components...
Public/Private Partnership for Development of the South Brunswick Station
Because of projections for continued residential and commercial growth and a large gap between stations, NJ TRANSIT decided to construct a new station in the Township of South Brunswick....
Allied Junction/Secaucus Transfer Station?A Private/Public Partnership
