Analysis of Potential Benefits and Costs of Adopting ASHRAE Standard 90.1-2001 as the Commercial Building Energy Code in Tennessee

Description: ASHRAE Standard 90.1-2001 Energy Standard for Buildings except Low-Rise Residential Buildings (hereafter referred to as ASHRAE 90.1-2001 or 90.1-2001) was developed in an effort to set minimum requirements for the energy efficient design and construction of new commercial buildings. The State of Tennessee is considering adopting ASHRAE 90.1-2001 as its commercial building energy code. In an effort to evaluate whether or not this is an appropriate code for the state, the potential benefits and c… more

Long-Lifetime Low-Scatter Neutron Polarization Target

Description: Polarized neutrons scattering is an important technology for characterizing magnetic and other materials. Polarized helium three (P-3He) is a novel technology for creating polarized beams and, perhaps more importantly, for the analysis of polarization in highly divergent scattered beams. Analysis of scattered beams requires specialized targets with complex geometries to ensure accurate results. Special materials and handling procedures are required to give the targets a long useful lifetime. In… more

Analytical Method for Measuring Total Protium and Total Deuterium in a Gas Mixture Containing H2, D2, and HD Via Gas Chromatography

Description: A new analytical technique has been developed that measures both total protium (H) and deuterium (D) in a gas mixture containing H2, D2, and HD. This new analytical technique uses a micro gas chromatograph (GC) with two molecular sieve columns. One column uses D2 as the carrier gas and the other uses H2 as the carrier gas. Laboratory tests have shown that when used in this configuration the GC can measure both total protium and total deuterium, each with a sensitivity of less than 20 ppm. This … more

Freedom of Speech and Press: Exceptions to the First Amendment

Description: The First Amendment to the United States Constitution provides that “Congress shall make no law . . . abridging the freedom of speech, or of the press. . . .” This language restricts government both more and less than it would if it were applied literally. It restricts government more in that it applies not only to Congress, but to all branches of the federal government, and to all branches of state and local government. It restricts government less in that it provides no protection to some typ… more

Analysis of Cladding Residues from the Dissolution of Irradiated Dresden-1 Reactor Fuel

Description: The primary goal of this work was to evaluate the efficacy of the chop-leach spent fuel dissolution process, with nitric acid dissolvent, for removing actinides and fission products from Zircaloy cladding to produce a cladding capable of meeting low-level waste (LLW) disposal criteria. Analysis of the cladding shows that actinides are present in the cladding at concentrations 50 to 400 times greater than the acceptable TRU limit in LLW. It appears that the nitric acid used for dissolution (init… more

Investigating the Molecular Mechanism of TSO1 Function in Arabidopsis cell division and meristem development

Description: Unlike animals, plants are constantly exposed to environmental mutagens including ultraviolet light and reactive oxygen species. Further, plant cells are totipotent with highly plastic developmental programs. An understanding of molecular mechanisms underlying the ability of plants to monitor and repair its DNA and to eliminate damaged cells are of great importance. Previously we have identified two genes, TSO1 and TSO2, from a flowering plant Arabidopsis thaliana. Mutations in these two genes … more

Tolerance of Three-Stage CIGS Deposition to Variations Imposed by Roll-to-Roll Processing: Phase II Annual Report, May 2003--May 2004

Description: Global Solar Energy, Inc. (GSE) and lower-tier subcontractor ITN Energy Systems, Inc. (ITN) are addressing process tolerance issues in this program. The definition and resolution of process tolerance issues satisfy many of the goals of the Thin Film Photovoltaics Partnerships Program (TFPPP). First, the investigation is likely to identify acceptable ranges for critical deposition parameters. This will have the benefit of providing upper and lower control limits for in-situ process monitoring co… more

Users' Guide to ADIC 1.1.

Description: This guide describes the use of the Automatic Differentiation in C (ADIC) system. ADIC is a suite of tools and libraries that automates the process of generating derivatives for scientific programs. In the context of solving PDEs, optimizations, sensitivity analysis, and inverse problems, researchers often require the derivatives {partial_derivative}f/{partial_derivative}x of a function f expressed as a program with respect to some input parameter(s) x. Automatic differentiation (AD) techniques… more

ML 3.1 developer's guide.

Description: ML development was started in 1997 by Ray Tuminaro and Charles Tong. Currently, there are several full- and part-time developers. The kernel of ML is written in ANSI C, and there is a rich C++ interface for Trilinos users and developers. ML can be customized to run geometric and algebraic multigrid; it can solve a scalar or a vector equation (with constant number of equations per grid node), and it can solve a form of Maxwell's equations. For a general introduction to ML and its applications, w… more
