Sodium Waste Technology : a Summary Report

Description: The Sodium Waste Technology (SWT) Program was established to resolve long-standing issues regarding disposal of sodium-bearing waste and equipment. Comprehensive SWT research programs investigated a variety of approaches for either removing sodium from sodium-bearing items, or disposal of items containing sodium residuals. The most successful of these programs was the design, test, and the production operation of the Sodium Process Demonstration Facility at ANL-W. The technology used was a seri… more

Insertion Device and Beam Line Plans for the Advanced Photon Source : a Report and Recommendations by the Insertion Device and Beam Line Planning Committee

Description: In the 7-GeV Advanced Photon Source (APS) Conceptual Design Report (CDR), fifteen complete experimental beam lines were specified in order to establish a representative technical and cost base for the components involved. In order to optimize the composition of the insertion devices and the beam line, these funds are considered a ''Trust Fund.'' The present report evaluates the optimization for the distribution of these funds so that the short- and long-term research programs will be most produ… more

A Review of Two-Phase Flow-Induced Vibration

Description: Two-phase flow exists in many shell-and-tube heat exchangers and power generation components. The flowing fluid is a source of energy that can induce small-amplitude subcritical oscillations and large-amplitude dynamic instabilities. In fact, many practical system components have experienced excessive flow-induced vibrations. To prevent unacceptable flow-induced vibration, we must understand excitation mechanisms, develop analytical and experimental techniques, and provide reliable design guide… more

Screening and Degradation Tests of Linear-Polymer Additives for District Heating Applications

Description: In closed-loop district heating and cooling (DHC) systems, the addition of a friction-reducing additive to the working fluid conveying energy between the energy sources and end users would allow increased load-handling capability (in an existing system) or the use of much smaller pipes and/or pumps (in a new system). As the first step in identifying friction-reducing additives that have a reasonable lifetime at DHC temperatures, two high-molecular-weight linear-polymer additives have been teste… more

Beyond "'Speedup": Performance Analysis of Parallel Programs

Description: This paper addresses the problem of measuring and analyzing the performance of fine-grained parallel programs running on shared-memory multiprocessors. Such processors use locking (either directly in the application program, or indirectly in a subroutine library or the operating system) to serialize accesses to global variables. Given sufficiently high rates of locking, the chief factor preventing linear speedup (besides lack of adequate inherent parallelism in the application) is lock contenti… more

X-ray Computed Tomography for Structural Ceramic Applications : Beam Hardening Corrections

Description: Beam hardening (BH), caused by the energy dependence of x-ray attenuation in materials, reduces the reliability of images generated by computed tomographic (CT) when polychromatic x-ray sources are used. The magnitude of the BH effect was calculated, and four different approaches to BH correction for CT imaging of ceramics were investigated: the ''water bag'' approach, pre-hardening of the beam by use of a filter, linearization correction, and dual-energy methods. The dual-energy approach appea… more

An Algebraic Theory of Program Specification and Correctness Using Symmetry Operations

Description: This report applies some methods from the theory of group representation to the questions of program specification and knowledge about programs. The theory is that of a program as a transformation on a state space, and operators commuting with that transformation being symmetries of the program, means of specifying properties, and generators of program invariants. Because a program can simulate a system in the real world, there is a corresponding model of engineered artifacts, that is, manmade … more

A Theory of Program Correctness, and Algorithms for Proofs

Description: A model of program correctness is given where a problem domain is defined by its language, variable names, and an abstract machine defining the semantics of the language. The set of all computations in this domain is shown to be a semigroup. A corresponding statement is true of a more general programming language. A program P in the general language is an element of the semigroup. If P performs computations in some domain, a connection can be established between P and the semigroup of computati… more

An Approach to Implementing State Space Searches on Heterogeneous Systems of Multiprocessors

Description: We report on experiments run on a set of shared-memory multiprocessors. Our goal was to demonstrate that one could conveniently utilize a set of shared-memory multiprocessors cooperatively working on typical state-space searches. We utilized a technology for writing portable code for multiprocessors, coded three depth-first state-space searches, and ran them on a set of multiprocessors. The final problem used substantial resources (over 65 hours on a single processor) and was successfully distr… more

The SUPRENUM (Supercomputer Numerical) Communications Subroutine Library for Grid-Oriented Problems

Description: In the application software development of the SUPRENUM project (the German supercomputer project) many parallel grid-oriented algorithms are being programmed, especially multigrid and computational fluid dynamics codes. As the communication tasks are similar, a central SUPRENUM communications library with subroutines covering all communication requirements of the applications programs has been created. By implementing versions of the library for the Intel iPSC hypercube and the planned SUPRENU… more

REDUCE-Aided Study of a Problem in Hermitian Matrix Theory

Description: Let A be any n x n positive definite matrix and B any n x n non-negative definite matrix. In an earlier paper we showed that for each n there is a real number t/sub n/> 2 such that if t <t/sub n/ then the solution X of the matrix equation A²X + XA² + tAXA = B is non-negative definite. For n = 2, t₂ = infinity and for n = 3, t₃ = 8. In this report we show that t₄ = 4, t₅ <3.02048507 and t₆ <2.62120330.

A Review of Parameterizations of Microphysical Processes in Clouds for Application in Models of Regional Atmospheric Deposition

Description: The literature on parameterizations of cloud microphysical processes was reviewed to examine the theoretical bases of those parameterizations and to evaluate their applicability to regional models. New parameterizations were produced by multiple regression upon the solution fields derived from simulations of a cloud model incorporating sophisticated microphysics. The currently available rates for cloud microphysical interactions were generally derived under the assumption that the size distribu… more
