Flood Control Doesn't Have to be Ugly
The recently completed flood control project in Rochester, Minn. shows how innovative engineering combined with aesthetically-sensitive design can integrate flood protection into an urban...
Divided We Fall
This article examines the aftermath of a falsework failure during the construction of a Mississippi River bridge in Minnesota. The author reviews the legal issues that arose from the collapse,...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Rising from the River
The Corps of Engineers completed construction of a 20 Million cu yd dredged material containment facility in the Delaware River in 1990. The authors examine the performance of the geotextile...
Journal of Architectural Engineering
The Journal of Architectural Engineering provides a multidisciplinary forum for dissemination of research-based engineering and technical information related to all aspects of building engineering design...
Calendar: Bridges 1996
Featured bridges are: Big Four Railroad Bridge (KY); Germantown Covered Bridge (OH); George Street Bridge (IN); Virgin River Bridge (UT); Bryan Bridge (NE); Brush Creek Bridge (KS); Natchez...
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...
Money-Saving Model
Determining whether dams and spillways along a river are adequate to handle potential floods can have far-reaching financial, as well as human ramifications. Watershed modeling studies...
Human Extender: A Material Handling System
A human's ability to perform physical tasks is limited by physical strength, not by intelligence. `Extenders' are a class of robot manipulators worn by humans to augment human mechanical...
Navigation of an Autonomous Robot Vehicle
The U.S. Air Force has developed an autonomous excavator capable of performing a variety of tasks at various Department of Defense facilities. Common to all the tasks is the need for autonomous...
GPS-Based Control for Space Vehicle Rendezvous
The recent advent of Differential Carrier Phase Global Position System (GPS) sensing has made it possible to determine relative positions of GPS receiver-equipped systems to less than...
Navigation of Autonomous Mobile Robots
An integrated navigational system for autonomous mobile robots features a primary navigator, such as an inertial navigation or a dead-reckoning system, and a secondary navigator. The secondary...
Intelligent Excavator Control for a Lunar Mining System
The benefits of utilizing local planetary resources are a large reduction in the cost of lifting materials from the earth's surface into earth orbit. Since the moon is one of the closest...
Control Model for Robotic Backhoe Excavation and Obstacle Handling
Excavation of soil and rock is a high volume and repetitive construction operation. Robots, which are suitable for incessant and repeated manipulations, can find many potential applications....
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....
Generalized Object Control and Assembly for Space Robots
This paper presents a Generalized Object Control framework which subsumes Unified Motion/Force Control and Object Impedance Control. Under this framework new forms of assembly primitives...
A Stewart Platform Lunar Rover
A lunar version of the Robocrane is being developed at the Robot Systems Division of the National Institute of Standards and Technology (NIST) to address the needs of NASA researchers....
An Intelligent Robotic Vehicle for Lunar/Martian Applications
This paper describes the research effort being undertaken at UA/NASA Space Engineering Research Center (SERC) towards a general-purpose intelligent robotic vehicle system (IRVS) for Lunar...
