Use of Manned Submersibles to Investigate Slumps in Deep Water Gulf of Mexico
The Johnson-Sea-Link manned submersible was used to investigate surface slumps in the deep water Gulf of Mexico. High quality and specifically placed seafloor cores, video tapes, 35 mm...
Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...
MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...
Computer Predictions of Thaw Beneath Gravel Embankments on Warm Permafrost
A computer model was used to simulate the freeze-thaw effects of gravel embankments on warm permafrost typical of south-central Alaska using a one-dimensional finite-difference code, FREZ1D....
Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...
Radar Monitoring of Ice on the Upper Niagara River
A standard marine radar was used during the winter of 1987-88 to evaluate its potential to monitor the presence and movement of ice in the Grass Island Pool area of the upper Niagara River....
Application of Ice/Structure Interaction Concepts to a Real Time Ice Risk Assessment Computer Model
The successful and safe operation of an Arctic offshore exploration structure greatly depends on the implementation of alerts procedures. In order to assess alerts levels, a computer model...
Approximate Methods of Structural Analysis: Principles and Pitfalls
In this modern age when the trend in structural engineering and structural engineering education is to make more and more use of computers and standard structural analysis programs, there...
The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...
Verification of Advanced Analysis Techniques
As a designer there is a concern over the complexity of analysis required by design specifications and building codes because it forces engineers into types of analysis for which many...
Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...
Verification of Approximate Methods of Structural Analysis
Sophisticated computer programs for the determination of the effects of instability on the inelastic stress resultants in steel structures will appear to be 'black boxes'...
Development of the ASME/NUPACK Code
A Committee has been active for 10 years to develop Code rules for the design, construction and in-service requirements of containment systems for nuclear spent fuel and high level radioactive...
Interpretation and Modelling Process of Bedrock Structures for Site Evaluation in Finland
The repository site for the final disposal of spent nuclear fuel in Finland will be selected by the end of the year 2000. Preliminary site investigations have been made in five areas since...
Developing an Education Program for Schools on Radioactive Waste Management
United Kingdom Nirex Limited is responsible for the development of a deep disposal facility for Britain's solid low and intermediate-level radioactive wastes. In line with...
Public Education, Public Confidence, and Public Acceptance of Radioactive Waste Management Facilities
This paper critically examines the conventional assumption that public opposition is a function of public illiteracy and emotionalism by reviewing recent articles on radioactive waste...
Flow and Transport Around a Noncontinuous Horizontal Layer at Yucca Mountain
Computer simulations were used to examine the effect of a noncontinuous horizontal layer on the flow field and contaminant transport of a simplified conceptual model. The domain consisted...
Unsaturated Flow Through a Variable Aperture Fracture in Topopah Spring Welded Tuff
The role of fractures in unsaturated flow through welded and nonwelded tuffaceous rocks is a fundamental question being addressed in performance assessment activities for the Yucca Mountain...
Transportation of Radioactive Materials Routing Analysis: The Nevada Experience
In 1987, the Nevada State Legislature passed a Bill requiring the Nevada Department of Transportation to develop and enforce a plan for highway routing of highway route controlled quantity...
Mechanistic Interpretation of Glass Reaction: Input to Kinetic Model Development
Actinide-doped SRL 165 type glass was reacted in J-13 groundwater at 90?C for times up to 278 days. The reaction was characterized by both solution and solid analyses. The glass was seen...
