A Finite Element Analysis of Mach Reflection by Using the Boussinesq Equation
The numerical analysis of Mach reflection, which is the reflection of an obliquely incident solitary wave by a vertical wail, is presented in this paper. For the mathematical model in...
Numerical Simulation of Hydraulic Jump
Hydraulic jump is numerically simulated by solving the laterally-averaged governing equations. The governing equations are derived for two-dimensional flow by laterally averaging the time...
Earthquake Design and Performance of Solid Waste Landfills
This proceedings contains invited and contributed papers for the technical session on
Strong-Motion Data Processing
Processing of strong-motion earthquake accelerograms is now carried out routinely on a world-wide basis. Two international workshops have given participants the opportunity to assess their...
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...
Thermoelastic Theory of Cylindrical Sandwich Shells with Piezoelectric Sensors or Actuators
Cylindrical sandwich shells with piezoelectric longitudinal and ring elements bonded to the outer and inner surfaces are considered in this paper. Thermal effects are included in the analysis,...
The Effect of Mobile Transporter Motion on the Space Station Attitude Control System
The effect of Mobile Transport (MT) motion on Space Station stability and the performance of the Attitude Control System (ACS) using Control Momentum Gyros (CMGs) is assessed. Analysis...
Space Commercialization: Problems of Law and Policy
This paper focuses on executive and legislative efforts to promote the growth of commercial space industries in the United States. After a discussion of the current, situation and efforts...
Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...
Behavior of Foundations Subjected to Large Ground Movements
The behavior of twelve linear test foundations above an advancing longwall coal mine panel was observed. Three phases of deformation were observed in the centerline foundations: tension,...
Dynamics of Nuclear Power Plant Structures with Foundation Interaction
This paper presents analyses and conclusions pertaining to a recorded earthquake motion felt at a nuclear power plant. The objective is to obtain frequency composition, assess damage potential,...
Effects of Site Conditions of Earthquake-Resistant Design of Structures
After a brief discussion of the importance of reliable establishment of design Earthquake Ground Motions (EQGMs) for efficient Earthquake-Resistant Design (EQ-RD) of structures, this paper...
The Use of Coda Waves for Characterizing the Site Effect on Strong Ground Motion
The well established separability of source, path and site effects on coda waves of local seismic events offers the most effective means for determining the site amplification factor empirically....
Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...
Damping Systems for Controlling Wind Induced Motions of Structures
This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems...
Some Aspects of Determination of Pile Capacity by the Wave Equation
This paper presents some new observations made during correlation study of pile capacity computed by wave equation analysis with failure load from static test. In order to determine proper...
Seismic Response and Retrofitting of Non-Ductile Reinforced Concrete Bridges
The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the...
