Structural Aspects of Femoral Head Osteonecrosis
Orthopaedic management of early stage osteonecrosis (ON) of the femoral head is aimed at delaying or preventing collapse of structurally weakened regions of repairing dead bone. The advent...
Biomechanical Model of a Lumbar Intervertebral Joint?A System Approach
This study was conducted to determine the forces sustained by the lumbar ligaments under flexion-compression using a two-dimensional equilibrium model. The lumbar motion segment was modeled...
Computational Mechanics: Constitutive Modeling and Performance Analysis
The availability of supercomputers in the 80's has brought about a revolution in the analysis and design of complex structures. Parallel with this, computers have played a...
Foias-Temam Approximations of Attractors for Galloping Oscillators
A method for the algebraic approximation of attractors recently developed by Foias and Temam is adapted for application to autonomous galloping oscillators. We compare results obtained...
Experimental and Numerical Chaos in Continuous Systems: Two Case Studies
Motivated by recent numerical investigations according to which certain types of deep-water compliant offshore structures may experience undesirable chaotic motions, two types of experimental...
Cumulants of the Nonlinear Combination of Independent Random Variables
A random variable of interest is often the sum of linear or nonlinear combinations of many independent random variables. In calculating the statistics of this random sum, advantages of...
The Application of Computerized Tomography for Determining Material Properties
X-ray computerized tomography (CT) is an imaging technique that has been used by the medical community for a number of years and is well documented. However, the adaption of this technique...
Nonlocality of Continuum Approximation of Microcracked Materials
A continuum with nonlocal damage has recently been shown to be an effective approach for the analysis of strain-softening structures. The basic idea is that only the damage, normally caused...

The
Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...
Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...
Highway Robbery: The Social Costs of Hazardous Materials Incidents on the Capital Beltway
In the summer of 1988, three major truck incidents involving hazardous materials occurred on the Capital Beltway in Washington, D.C. This paper estimates the delays that were incurred...
StateGEN/StateNET and DOT Guidelines: Tools for Highway Routing of Hazardous Materials
Under the sponsorship of the U.S. Department of Energy Office, of Defense Programs, Sandia National Laboratories' Transportation Technology Center has developed computerized...
Are We Ready to Face the Geotechnical Challenges of the 21st Century?
The geotechnical engineering profession faces a bright future as many of the issues of interest to society today relate in some form to knowledge of earth sciences. Hazardous waste, environmental...
The Pressuremeter: Some Special Applications
The preboring pressuremeter has been used for foundation design for many years. Some recent developments are presented which extend the applications of the pressuremeter. These developments...
Hypermedia and its Application to Geotechnical Databases
The concept of hypermedia has the potential for greatly enhancing existing database management software. In the present paper the concept of hypermedia is briefly described, the nature...
Geotechnical Database Management Systems for Boston's Central Artery/Harbor Tunnel Project
This paper presents a geotechnical computer application currently in use on Boston's Central Artery/Harbor Tunnel (CA/T) Project. The application is designed to manage subsurface...
Relational Database Design and Technology
Logical and physical design of a Relational Database Management System (RDBMS) is presented with a simple geotechnical database example. Fundamental relational database design principles...
Automated Performance Monitoring of U.S. Dams
The purpose of this paper is to provide a summary of a comprehensive report prepared by USCOLD on General Guidelines and Current U.S. Practice in Automated Performance Monitoring of Dams....
Recent Developments in Hardware and Data Processing for Telemonitoring Various Structures
Some of the latest automated centralized monitoring systems being used by civil engineers in France shall be reviewed, along with details of the benefits from this approach and some of...
