Eddy Pump Dredging Demonstration at Cresta Reservoir
A demonstration test of a new environmentally ifiendly slurry dredging technology using the EDDY Pump, a patented vortex slurry pump, was perfbrmed in 1994 at Cresta Reservoir in northern...

Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...

Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...

Engineering Mechanics
This proceedings, Engineering Mechanics: Proceedings of the 10th Conference, contains papers presented at the Conference held in Boulder, Colorado,...

Demolishing NAPLs
Dynamic Underground Stripping is a combination of in situ steam injection, electrical resistance heating, and fluid extraction for rapid removal...

Earthquake Design and Performance of Solid Waste Landfills

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,...

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...

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...

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...

On the Dynamics and Control of Flexible Orbiting Systems: An Approach with Application
A relatively general formulation for studying the dynamics and control of an arbitrary spacecraft, with interconnected flexible, deployable and articulating structural members, is reviewed...

Improving Dynamic Finite Element Models Using Test Data
A structural optimization based method was developed to improve the finite element model to achieve good agreement with the test results. The modal displacements at critical locations...

Dynamic Analysis of a High Speed Transport Model by Using a Piecewise Continuous Timoshenko Beam Model
Conventional treatment of structural dynamic analysis and control is based on the finite element structural model. But such a treatment uses a very large number of elements which is usually...

Braced Double Skinned Structure in Lunar Application
A parametric study is designed to evaluate a proposed Braced Double Skinned roof structure utilizing extrapolated theoretical solutions i.e. Navier's solution and Levy's solution. A Finite...

Comparison of Donnell and Higher Order Nonlinear Models for Dynamically Loaded Composite Plates and Shells
The dynamic buckling behavior of composite cylindrical shells subjected to a transverse point load is considered. The behavior of undamped cylindrical shells of varying radii is analyzed...

Dynamics of Laminated Plates with Layer Waviness
Composite structures usually exhibit a high strength-to-weight ratio as compared to traditional structural materials. This makes them attractive solutions in many aerospace applications....
