Durability, Mechanical, and Thermal Properties of Experimental Glass-Ceramic Forms for Immobilizing ICPP High Level Waste
The high-level liquid waste generated at the Idaho Chemical Processing Plant (ICPP) is routinely solidified into granular calcined high-level waste (HLW) and stored onsite. A research...

Boundary Integral Methods for Unsaturated Flow
A boundary integral equation method (BIEM) is described for numerical analysis of quasilinear steady unsaturated flow in homogeneous material. The applicability of the exponential model...

A Formalism to Generate Probability Distributions for Performance-Assessment Modeling
A formalism is presented for generating probability distributions of parameters used in performance-assessment modeling. The formalism is used when data are either sparse or nonexistent....

Three-Dimensional Thermal Analysis for Temperature Distribution in Geological Formation
A three-dimensional conduction heat transfer program has been developed for use on microcomputer for thermal analysis of a conductive medium subject to, finite length heat sources. The...

System Analysis Dual-Purpose Repository New Results of Temperature Calculations
As design concept for a high-level waste (HLW) final repository the emplacement of reprocessing wastes and spent fuel elements of different types in a common repository is being studied...

Total-System Analyzer for Performance Assessment of Yucca Mountain
The Total-System Analyzer is a modular computer program for probabilistic total-system performance calculations. The code employs stratified random sampling from model parameter distribution...

Runoff Modeling Using the Geomorphological Instantaneous Unit Hydrograph and ARC/INFO Geographic Information System
The degree to which the spatial variability of watershed characteristics (geographical and climatological) is recognized for simulating watershed runoff depends on the hydrologic model...

A Prototype Distributed Processing System Water Control Data Processing at Tulsa District U.S. Army Corps of Engineers
The Tulsa District, Corps of Engineers operates 50 multi-purpose reservoirs controlling runoff from all or parts of 7 states. These reservoirs are operated for flood control, water supply,...

NEXRAD Input to Real-Time Reservoir Regulation
The Corps of Engineers has a need for radar information to enhance rain gauge measurements in determining average rainfall over a particular basin for hydrological forecast models used...

A Bivariate Stochastic Reservoir Model
A bivariate distribution of peak flows and volumes is derived taking into account their correlation structure. This distribution is then used to derive reservoir operation curves which...

Effect of Storm Distribution on Watershed Stormwater Management
This paper presents a case study illustrating the effect of the selection of rainfall distribution pattern upon the ability of a calibrated rainfall-runoff simulation model to replicate...

A New Finite Element Formulation of the Generalized Laminated Plate Theory
The Generalized Laminate Plate Theory (GLPT) predicts stress distributions in laminated composite plates with accuracy comparable to a full three-dimensional analysis. The original implementation...

p-Version Three Dimensional Solid Element for Heat Conduction
This paper presents a finite element formulation for a three dimensional twenty-seven node hierarchical solid element for heat condition where the element temperature approximation can...

Stochastic Response Analysis of Nonlinear Plane Trusses with Spatial Variability
This study considers responses of geometrically and materially nonlinear plane truss structures with spatially uncertain system parameters, subjected to random excitations. A stochastic...

Three-Dimensional Finite Element Analysis of Stress and Activation in the Heart
A finite element (FE) method has been developed for three-dimensional (3D) analysis of stress distributions and activation patterns in the left and right ventricles of the canine heart....

Finite Element Stress Analysis of a Spinal Segment
A large number of factors need to be determined to understand the biomechanics of a surgical procedure about the lumbar spine. Some of these factors are amenable to experimental investigations...

In-Vitro Measurement of Static Contact Pressure Distribution in Synovial Joints
The objective of this presentation is, at first, to review the various approaches to the measurement of contact pressure distribution in synovial joints, and then to describe the development...

Biomechanics of Local Articular Incongruities
Abnormalities of intra-articular contact near sites of local surface incongruity are frequently associated with secondary osteoarthrosis. We here review a series of experimental and computational...

Comparative Time Domain Analysis of Some Available Analytical and Empirical Expressions for the Spatial Variability of Seismic Ground Motions
Simulations in space and time based on models for the spatial variability of seismic ground motions are generated. Displacement time histories are simulated through the spectral representation...

Vibration of Plates with Corner Stress Singularities
A method of analysis is presented to determine the free vibration frequencies of plates having corner stress singularities. Displacements are assumed in the form of polynomials, and corner...
