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...
Reliability and Response Control of R/C Buildings
A damage model is summarized for the assessment of seismic damage of reinforced concrete structures. The model is to evaluate specific buildings that were damaged in Mexico City during...
I.P.L. Space Trusses: Structural Performance and Analysis
The utilization of the fast working massively parallel computers in solving intense numerical problems, in the field of structural engineering left disappointed many of practical engineers....
Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
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...
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...
Autonomous Navigation for Structured Exterior Environments
The Telemanaged Mobile Security Station (TMSS) was developed at Sandia National Laboratories to investigate the role of mobile robotics in exterior perimeter security systems. A major...
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
