Development of metrological NDE methods for microturbine ceramic components

Description: In this work, X-ray computed tomographic imaging technology with high spatial resolution has been explored for metrological applications to Si{sub 3}N{sub 4} ceramic turbine wheels. X-ray computed tomography (XCT) data were acquired by a charge-coupled device detector coupled to an image intensifier. Cone-beam XCT reconstruction algorithms were used to allow full-volume data acquisition from the turbine wheels. Special software was developed so that edge detection and complex blade contours cou… more

Experiences with TCP/IP over an ATM OC12 WAN

Description: This paper discusses the performance testing experiences of a 622.08 Mbps OC12 link. The link will be used for large bulk data transfer, and as such, of interest are both the ATM level throughput rates and end-to-end TCP/IP throughput rates. Tests were done to evaluate the ATM switches, the IP routers, the end hosts, as well as the underlying ATM service provided by the carrier. A low level of cell loss, (resulting in <.01 % packet loss), decreased the TCP throughput rate considerably when o… more

The investigation of phase evolution in composite ceramic superconductors using Raman microscopy techniques

Description: Raman microspectroscopy and imaging techniques have been used to investigate key mechanistic features that influence the formation of layered Bi- and Tl-based superconducting phases during the thermal treatment employed to produce BSCCO and TBCCO composite conductors. Seminal information gained from these studies includes the location of lead-rich nonsuperconducting second phases (NSPS) and the identification of the constituent phases in certain NSP agglomerations that tend to resist dissipatio… more

The NetLogger Methodology for High Performance Distributed Systems Performance Analysis

Description: The authors describe a methodology that enables the real-time diagnosis of performance problems in complex high-performance distributed systems. The methodology includes tools for generating precision event logs that can be used to provide detailed end-to-end application and system level monitoring; a Java agent-based system for managing the large amount of logging data; and tools for visualizing the log data and real-time state of the distributed system. The authors developed these tools for a… more

A Network-Aware Distributed Storage Cache for Data Intensive Environments

Description: Modern scientific computing involves organizing, moving, visualizing, and analyzing massive amounts of data at multiple sites around the world. The technologies, the middleware services, and the architectures that are used to build useful high-speed, wide area distributed systems, constitute the field of data intensive computing. In this paper the authors describe an architecture for data intensive applications where they use a high-speed distributed data cache as a common element for all of th… more

Phase stability domains of (Bi,Pb-2223): Data sources, correlation, and assessment

Description: An assessment of the phase stability of lead-doped Bi-2223, (Bi,Pb)-2223, as a function of temperature and partial pressure of oxygen, p(0{sub 2}), derived from equilibration and electromotive force studies carried out by numerous groups of investigators is presented. The data obtained from this assessment, coupled with additional more recent data from the laboratory, can be used to estimate the stability of this promising high-{Tc} bismuth cuprate system in the temperature range from 650 to 87… more

Scenario analysis of hybrid class 3-7 heavy vehicles.

Description: The effects of hybridization on heavy-duty vehicles are not well understood. Heavy vehicles represent a broader range of applications than light-duty vehicles, resulting in a wide variety of chassis and engine combinations, as well as diverse driving conditions. Thus, the strategies, incremental costs, and energy/emission benefits associated with hybridizing heavy vehicles could differ significantly from those for passenger cars. Using a modal energy and emissions model, they quantify the poten… more

Through the looking glass: Unraveling the network structure of coal

Description: Since the original idea by Sanada and Honda of treating coal as a three-dimensional cross-linked network, coal structure has been probed by monitoring ingress of solvents using traditional volumetric or gravimetric methods. However, using these techniques has allowed only an indirect observation of the swelling process. More recently, the authors have developed magnetic resonance microscopy (MRM) approaches for studying solvent ingress in polymeric systems, about which fundamental aspects of th… more

Ballistic Experiments with Titanium and Aluminum Targets

Description: During the course of the project we conducted two sets of fundamental experiments in penetration mechanics in the LLNL Terminal Ballistics Laboratory of the Physics Directorate. The first set of full-scale experiments was conducted with a 14.5mm air propelled launcher. The object of the experiments was to determine the ballistic limit speed of 6Al-4V-alloy titanium, low fineness ratio projectiles centrally impacting 2024-T3 alloy aluminum flat plates and the failure modes of the projectiles and… more

The behavior of silicon and boron in the surface of corroded nuclear waste glasses : an EFTEM study.

Description: Using electron energy-loss filtered transmission electron microscopy (EFTEM), we have observed the formation of silicon-rich zones on the corroded surface of a West Valley (WV6) glass. This layer is approximately 100-200 nm thick and is directly underneath a precipitated smectite clay layer. Under conventional (C)TEM illumination, this layer is invisible; indeed, more commonly used analytical techniques, such as x-ray energy dispersive spectroscopy (EDS), have failed to describe fully the local… more

Decay rates of spherical and deformed proton emitters

Description: Using Green's function techniques, the authors derive expressions for the width of a proton decaying state in spherical and deformed nuclei. The authors show that the proton decay widths calculated by the exact expressions of Maglione et al. are equivalent to the distorted wave expressions of Bugrov et al., and that of {angstrom} berg et al. in the spherical case.

Isospin-Forbidden B-Delayed Proton Emission

Description: The effects of isospin-symmetry breaking on proton emission following {beta}-decay to the isobaric analog state are discussed in detail. Of particular importance is the mixing with a dense background of lower isospin states, whose properties are not well known. The possibility of observing T=4 states in even-even, N=Z nuclei, which is viable if the decay proceeds via isospin-forbidden particle emission, is also discussed.
