20000062724 International Atomic Energy Agency, International Nuclear Data Committee, Vienna, Austria Nuclear data libraries and online services. An introduction to the data types and services available from the IAEA Nuclear Data Section Oblozinsky, P.; Schwerer, O.; Sep. 30, 1998; 15p; In English; Nuclear Reaction Data and Nuclear Reactors: Physics, Design and Safety, 23 Feb. - 17 Mar. 1998, Trieste, Italy Report No.(s): DE99-607945; INDC(NDS)-387; No Copyright; Avail: Department of Energy Information Bridge The IAEA Nuclear Data Section provides convenient, cost-free access to the world’s most comprehensive collection of numerical nuclear physics data. These nuclear data libraries result from a worldwide cooperation of nuclear data centres coordinated by the IAEA. An introduction is given to the various nuclear data types and libraries with particular emphasis to online services via the Internet. This paper summarizes a presentation for the IAEA Workshop on ’’Nuclear Reaction Data and Nuclear Reactors: Physics, Design and Safety’’ held at ICTP Trieste, Italy, 23 February - 17 March 1998.

The research during this period was performed in three primary, but related, areas. 1. Evaluation of integrated information adaptive imaging. 2. Improvements in memory utilization and performance of the multiscale retinex with color restoration (MSRCR). 3. Commencement of a theoretical study to evaluate the non-linear retinex image enhancement technique. The research resulted in several publications, and an intellectual property disclosure to the NASA patent council in May, 1999.

L.; Hahn, H. A.; Pond, D. J.; May 27, 1998; 103p; In English Report No.(s): DE99-001170; LA-UR-98-2400; No Copyright; Avail: Department of Energy Information Bridge The Technique for Human Error Analysis (ATHEANA) is a newly developed human reliability analysis (HRA) methodology that aims to facilitate better representation and integration of human performance into probabilistic risk assessment (PRA) modeling and quantification by analyzing risk-significant operating experience in the context of existing behavioral science models. The fundamental premise of ATHEANA is that error-forcing contexts (EFCs), which refer to combinations of equipment/material conditions and performance shaping factors (PSFs), set up or create the conditions under which unsafe actions (UAs) can occur. Because ATHEANA relies heavily on the analysis of operational events that have already occurred as a mechanism for generating creative thinking about possible EFCs, a database, called the Human Events Reference for ATHEANA (HERA), has been developed to support the methodology. This report documents the initial development efforts for HERA.

However, it should be remembered that years of effort were required to achieve the standardization that has supported the growth of the CD industry. Incompatibilities in the interpretation of the ISO-9660 standard on different operating systems had to be dealt with, and the imprecise specifications in the Orange Book Part n and Part Hi led to incompatibilities between CD-R media and CD-R recorders. Some of these issues were presented by the authors at Optical Data Storage ’95. The major current problem with the use of CD technology is the growing volume of digital data that needs to be stored. CD-ROM collections of hundreds of volumes and CD-R collections of several thousand volumes are 216
ecoming almost too cumbersome to be useful. The emergence of Digital Video Disks Recorder (DVD-R) technology promises to reduce the number of discs required for archive applications by a factor of seven while providing improved reliability. It is important to identify problem areas for DVD-R media and provide guidelines to manufacturers, file system developers and users in order to provide reliable data storage and interchange. The Data Distribution Laboratory (DDL) at NASA’s Jet Propulsion Laboratory began its evaluation of DVD-R technology in early 1998. The initial plan was to obtain a DVD-Recorder for preliminary testing, deploy reader hardware to user sites for compatibility testing, evaluate the quality and longevity of DVD-R media and develop proof-of-concept archive collections to test the reliability and usability of DVD-R media and jukebox hardware.

The goal is to develop a policy that would require data release at the same time as publication of the first scientific description of the research project that produced the data. Design and implementation of the policy should emphasize incentives and advantages of early data release in terms of possibilities of cooperation and the opportunity for the community to develop large integrated data sets to derive synthesized science products.

Starting with the 1997 flight season, a drastically different paradigm has been used for the processing of AVI- RIS data. This change was made possible by the recent development of and related availability of affordable data storage devices.

A COIN is a large multi-agent system where: (i) There is no centralized communication among agents; (ii) There is no centralized control among agents; (iii) There is a well-specified global objective, and we are confronted with the inverse problem of how to configure the system to achieve that objective. (iv) Agents are ”greedy” in that they act to try to optimize their own utilities, without explicit regard to cooperation with other agents. Many conventional approaches to designing large distributed systems to optimize a world utility attempt to explicitly model the dynamics of the overall system. They then hand-tune the interactions between the agents to ensure that those agents ”cooperate” as far as the world utility is concerned. This approach is labor-intensive, often results in highly nonrobust systems, and usually results in design techniques that have limited applicability. In contrast, in our approach we wish to solve the COIN design problems implicitly, via the ”adaptive” character of Reinforcement Learning (RL) algorithms that each of the agents run. This approach introduces an entirely new, profound design problem: Assuming the RL algorithms are able to achieve high rewards, what reward functions for the individual agents will, when pursued by those agents, result in high world utility? How, without any detailed modeling of the overall system, can one set the utility functions for the RL algorithms 217
