Risk of Extreme and Catastrophic Events
Assessing the extreme tails of a probability distribution, where events of very low probability can nevertheless lead to catastrophic outcomes, is one of the most widely discussed and...

Boston's Commuter Comeback
More than 30 years after its abandonment, the Old Colony Railroad in Massachusetts is being revived through a �480 million rehabilitation project to serve residents southeast of Boston....

Trenchless Relief
During wet weather, stormwater infiltration/inflow into the sewer system increases wastewater flows by 8-12 times the average dry weather flow in several interceptors operated by the Central...

Depressing Traffic Top-Down
Top down construction will permit the City and County of Denver to maintain traffic at two congested intersections while a tunnel is driven below them. The project, which will carry Speer...

Doubling A Pipeline
The 36 in. natural gas pipeline built 32 years ago by Pacific Gas and Electric (PG&E) its subsidiary Pacific Gas Transmission (PGT) from Canadian fields to central California has...

A Feature Based Path Planning System for Robotic Stenciling of Roadway Markings
Roadway sign stenciling is a hazardous operation exposing the roadway maintenance and construction crew to on going traffic. The current practice involves manual painting using a mechanical...

An Experiment in Mobile Robotic Cooperation
This paper describes the results of an experiment in real mobile robot cooperation which utilizes a fully distributed, cooperative software mechanism we have previously developed in simulation....

Automated Sensor Tester
The Automated Sensor Tester (AST) is being developed by Sandia National Laboratories for the Department of Energy (DOE) to be a tool to aid in testing exterior intrusion detection sensors...

Environmental Hardening of a Mobile-Manipulator System for Nuclear Environments
The research report involves the radiation hardening of a commercially-available, mobile robot, the REMOTEC ANDROS. This hardening effort will culminate in the availability of a mega-rad...

An Overview of the Accident Response Mobile Manipulation System (ARMMS)
The development of a high mobility platform integrated with high strength manipulation is under development at Sandia National Laboratories. The mobility platform used is a High Mobility...

Generic Data Acquisition System for Robotic Waste Characterization
This paper describes a generic data acquisition system for robotic characterization of DOE production facilities and waste sites. While the specific suite of characterization sensors on...

Robotic Workcell for Waste Handling
During the sorting and repackaging of recovered waste, robotic systems for grasping and manipulating odd-shaped objects of varying sizes will be needed. Also, during the removal of buried...

A New Robotic System Concept for Automating Highway Maintenance Operations
The purpose of this paper is to present the Tethered Mobile Robot (TMR) concept, a new robotic system for automating highway maintenance operations. The operational requirements of this...

Demands and Satisfiers for Automation and Robotics in Construction: Differences Between Japan and the United States
The construction industries in Japan and the United States face problems of productivity, quality, safety, and skilled labor shortages. Automation and robotics are often proposed as solutions...

Robotic Options for Mining of Near-Earth Objects
The mining and processing of a Near-Earth Object (NEO) should be as simple and as robust as possible - the fewer processes and parts the better. Reliability and survivability of the total...

Bubba, A Teleoperated Countermine Vehicle
A recent countermine test program required the development of Bubba, a 5 ton, 6 wheel drive, M-923 military truck converted to teleoperation. The Mine Detection by Energetic Photons (MIDEP)...

A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...

Reliability of Structures for the Moon
The subject of risk and reliability for lunar structures is introduced and critical issues deliberated. A tensile structure is considered as an example in order to become more specific...

Global Environmental Change: Geoengineering Technology
The `overview effect,' looking at the entire Planet Earth from space, has communicated the reality of the limited extent of our environment and its apparent fragility. Space continues...
