Journal of Hydrologic Engineering
The Journal of Hydrologic Engineering disseminates information on the development of new hydrologic methods, theories, and applications to current engineering problems. The journal publishes papers on...
Dredging Up the Past
Disposal of contaminated dredged materials has become a national problem. The nation's ports and harbors have postponed dredging because of the cost and difficulty in finding...
Cleanup Solution--Conflict Resolution
Distrust and misinformation often prevent timely resolution of ground-water contamination problems. In Toms River, N.J., engineers used a computer-generated model of the cleanup site in...
Is Virtual Reality for Real?
Virtual reality, an advanced visualization technology, will change certain aspects of civil engineering. The method allows people to simulate conditions, render designs and test these...

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...
Static and Dynamic Properties of Gravelly Soils
The behavior of gravelly soils has been the focus of much research in recent years. Large-scale penetration and triaxial tests, shear-wave velocity measurements, insitu freezing and sampling,...
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,...
Developing Plans for Robotic Excavators
We would like a robot excavator that is able to excavate a volume of soil according to specification. To this end we have developed a general method that can be used to provide prescriptions...
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...
Recent Developments in the Robotic All Terrain Lunar Exploration Rover (RATLER) Program
The Robotic All-Terrain Lunar Exploration Rover (RATLER) is a four wheeled all-wheel-drive dual-body vehicle. A uniquely simple method of chassis articulation is employed which allows...
Inertially Favorable Trajectories for Robot Motion in Space
Robot manipulators generally display non-linear coupled dynamic forces which increase with speed. Efficiencies can be achieved by finding trajectories which take advantage of those inertial...
