Landslides under Static and Dynamic Conditions
Analysis, Monitoring, and Mitigation
It is important to consider both the geotechnical engineering and the engineering geology implications of static and dynamic behavior of landslides. In studying landslides one must consider...
Waste Containment Facilities
This book presents a comprehensive description of recommended procedures for construction quality assurance (CQA) and control (CQC) for waste containment facilities. Chapter 1 describes...
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,...
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...
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...
The Role of Computer Graphics in Teleoperation
Computer graphics techniques developed by the Advanced Teleoperation (ATOP) Project at the Jet Propulsion Laboratory (JPL) for the control of remote manipulators, primarily for space applications,...
Real-time Motion Vision for Robot Control in Unstructured Environments
The control of robots in unstructured environments demands real-time, general purpose vision. We have designed a visual tracking system which makes use of motion to pick out and track...
Application of Virtual Reality to Space Robotics Operations
This paper discusses a Virtual Reality (VR) simulation under development by the Automation and Robotics (A&R) Division at the Johnson Space Center (JSC). Over the past twelve years,...
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...
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...
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....
Goals and Requirements for Scientific Lunar Rovers
The detailed science requirements for future lunar rovers should, of course, be based on achievable science goals and objectives. It is clear that lunar geoscience will benefit by robotic...
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....
The Kinematic Design of a Robotic Large Space Structure Construction Service
Researchers at the University of Maryland's Robotics Research Lab are applying a kinematic rapid proto-typing methodology to the development of a commercial robotics service for the construction...
The Optimal Selection of Robot Modules for Space Manipulators
Monolithic robot systems are poorly suited to the broad requirements and uncertainties of space automation applications. Designers have considered building many robots, each of which can...
