Comparison of the calculated and measured stability of a NbTi cable-in-conduit conductor

Description: Calculated curves of cable-in-conduit conductor energy stability margins vs. current are compared to experimental curves obtained at Oak Ridge National Laboratory for NbTi single triplex conductors. The conductors ranged in length from 1.8 m to 4.8 m, and had no imposed helium flow. The initiating heat pulse was applied for 16.7 ms over the entire conductor length. The calculated stability curves display the large decrease in energy margin from the low current and high energy margin {open_quote… more

A JAVA User Interface for the Virtual Human

Description: A human simulation environment, the Virtual Human (VH), is under development at the Oak Ridge National Laboratory (ORNL). Virtual Human connects three-dimensional (3D) anatomical models of the body with dynamic physiological models to investigate a wide range of human biological and physical responses to stimuli. We have utilized the Java programming language to develop a flexible user interface to the VH. The Java prototype interface has been designed to display dynamic results from selected p… more

An implementation of a medium resolution minefield model in the Joint Conflict Model

Description: An implementation of a new, flexible, and realistic representation of conventional minefields in the Joint Conflict Model (JCM) is presented. The model includes important aspects of minefield effects on battlefield entities and of breaching devices on minefields. The model is designed at ``medium resolution,`` that is, it is general enough to depict a wide variety of tactical situations accurately; however, it only represents tactically significant aspects of mine warfare, discarding or aggrega… more

Massively Parallel Linear Stability Analysis with P_ARPACK for 3D Fluid Flow Modeled with MPSalsa

Description: We are interested in the stability of three-dimensional fluid flows to small dkturbances. One computational approach is to solve a sequence of large sparse generalized eigenvalue problems for the leading modes that arise from discretizating the differential equations modeling the flow. The modes of interest are the eigenvalues of largest real part and their associated eigenvectors. We discuss our work to develop an effi- cient and reliable eigensolver for use by the massively parallel simulatio… more

Parallel unconstrained minimization of potential energy in LAMMPS

Description: This report describes a new minimization capability added to LAMMPS V4.0. Minimization of potential energy is used to find molecular conformations that are close to structures found in nature. The new minimization algorithm uses LAMMPS subroutines for calculating energy and force vectors, and follows the LAMMPS partitioning scheme for distributing large data objects on multiprocessor machines. Since gradient-based algorithms cannot tolerate nonsmoothness, a new Coulomb style that smoothly cuts … more

Single identities for lattice theory and for weakly associative lattices

Description: We present a single identity for the variety of all lattices that is much simpler than those previously known to us. We also show that the variety of weakly associative lattices is one-based, and we present a generalized one-based theorem for subvarieties of weakly associative lattices that can be defined with absorption laws. The automated theorem-proving program OTTER was used in substantial way to obtain the results.

Improving analytical understanding through the addition of information: Bayesian and hybrid mathematics approaches

Description: Safety analysts frequently must provide results that are based on sparse (or even no) data. When data (or more data) become available, it is important to utilize the new information optimally in improving the analysis results. Two methods for accomplishing this purpose are Bayesian analysis, where "prior" probability distributions are modified to become "posterior" distributions based on the new data, and hybrid (possibilistic/probabilistic analysis) where possibilistic "membership" portrays th… more

The characteristic analysis of a hybrid multifluid turbulent-mix model

Description: A thorough analysis of the characteristics of a multifluid turbulent mix model in the case of one-dimensional two phase flows is presented under various physical circumstances. It has been found that the new hybrid multifluid turbulent mix model has all real characteristics if either real or turbulent viscosity is present. When real viscosity vanishes, the model still has all real characteristics for zero relative motion between fluids. For nonzero relative motions between fluids, the model wil… more

Office of Inspector General audit of alternatives to testing at the Tonopah Test Range

Description: Since the 1950s, the Department of Energy (DOE) and its predecessor agencies have done weapons program testing at the Tonopah Test Range (Tonopah). Beginning the in 1990s, DOE`s testing at Tonopah declined dramatically. This decline was coincident with the signing of various international treaties, the end of the Cold War, and the movement of some types of tests to other ranges. As a result, Tonopah was left with some bomb and work-for-others testing. The objective of this audit was to determin… more

An object-oriented decomposition of the adaptive-hp finite element method

Description: Adaptive-hp methods are those which use a refinement control strategy driven by a local error estimate to locally modify the element size, h, and polynomial order, p. The result is an unstructured mesh in which each node may be associated with a different polynomial order and which generally require complex data structures to implement. Object-oriented design strategies and languages which support them, e.g., C++, help control the complexity of these methods. Here an overview of the major class… more
