Efficient, intelligent systems for navigating the biological literature. Final report, September 15, 1993--September 14, 1996
The biological literature is huge and increasingly moving to electronic form. By developing a variety of new techniques, it should be possible to take advantage of this huge and growing electronic store. Computers should allow one to use the literature with greater efficiency and insight to disseminate information and to advance scientific understanding. Though there is a great deal of research and development effort focused on electronic text, e.g., the Digital Libraries initiative, little attention has been paid to the diagrammatic content of documents. However, it is common knowledge among biologists, and scientists in general, that the figures in documents are of critical importance. Little work has been done to develop principles and systems for analyzing, representing, and indexing and searching the diagrammatic content of electronic documents. This has been the main thrust of this research project. The primary work in the world on the analysis of graphics in documents has been focused on low-level issues relating to scanning legacy documents (hardcopy) and trying to discover the graphics elements in them. Graphics files, as opposed to image files, have lines, curves, polygons, text, etc., represented as discrete objects, as they are originally generated in drawing and graphing applications. This has …

Navigating nuclear science: Enhancing analysis through visualization
Data visualization is an emerging technology with high potential for addressing the information overload problem. This project extends the data visualization work of the Navigating Science project by coupling it with more traditional information retrieval methods. A citation-derived landscape was augmented with documents using a text-based similarity measure to show viability of extension into datasets where citation lists do not exist. Landscapes, showing hills where clusters of similar documents occur, can be navigated, manipulated and queried in this environment. The capabilities of this tool provide users with an intuitive explore-by-navigation method not currently available in today`s retrieval systems.

Review and evaluation of the Office of Science and Technology`s Community Leaders Network
This report constitutes a review and evaluation of the Community Leaders Network (CLN), an informally structured national stakeholder group sponsored by the Department of Energy (DOE) Environmental Management (EM) Program`s Office of Science and Technology (OST) to obtain citizen input into the technology research and development programs of the OST. Since the CLN`s inception in 1993, its participants, currently numbering about 35 members mostly from jurisdictions hosting DOE waste management and environmental remediation sites, and its clients (i.e., OST) have invested substantial resources to develop the capability to enhance technology development and deployment activities through proactive stakeholder involvement. The specific objectives of the CLN are to: provide feedback and input to OST on technology development activities; provide information on OST ideas and approaches to key stakeholder groups, and provide input to OST on stakeholder concerns and involvement.

Los Alamos National Laboratory Science Education Program. Annual progress report, October 1, 1995--September 30, 1996
The National Teacher Enhancement program (NTEP) is a three-year, multi-laboratory effort funded by the National Science Foundation and the Department of Energy to improve elementary school science programs. The Los Alamos National Laboratory targets teachers in northern New Mexico. FY96, the third year of the program, involved 11 teams of elementary school teachers (grades 4-6) in a three-week summer session, four two-day workshops during the school year and an on-going planning and implementation process. The teams included twenty-one teachers from 11 schools. Participants earned a possible six semester hours of graduate credit for the summer institute and two hours for the academic year workshops from the University of New Mexico. The Laboratory expertise in the earth and environmental science provided the tie between the Laboratory initiatives and program content, and allowed for the design of real world problems.

Information integration for data fusion
Data fusion has been identified by the Department of Defense as a critical technology for the U.S. defense industry. Data fusion requires combining expertise in two areas - sensors and information integration. Although data fusion is a rapidly growing area, there is little synergy and use of common, reusable, and/or tailorable objects and models, especially across different disciplines. The Laboratory-Directed Research and Development project had two purposes: to see if a natural language-based information modeling methodology could be used for data fusion problems, and if so, to determine whether this methodology would help identify commonalities across areas and achieve greater synergy. The project confirmed both of the initial hypotheses: that the natural language-based information modeling methodology could be used effectively in data fusion areas and that commonalities could be found that would allow synergy across various data fusion areas. The project found five common objects that are the basis for all of the data fusion areas examined: targets, behaviors, environments, signatures, and sensors. Many of the objects and the specific facts related to these objects were common across several areas and could easily be reused. In some cases, even the terminology remained the same. In other cases, different areas had …

Literature search on the use of resins for treatment of radioactive wastes
Over 100 commercial providers with mixed-waste treatability capabilities exist in the US. The maturity level of these technologies varies from a bench scale to a pilot or a commercial scale. The techniques include deactivation, chemical oxidation, recovery of metals, stabilization, vitrification, incineration, biodegradation, and chemical extraction. This report focuses on the use of resins to remove actinides and heavy metals from aqueous waste streams. Only the literature that described resins with high removing efficiency are presented here. The majority of the literature reviewed are proceedings and national or international reports ordered through the Berkeley Lab Library. Some of the reports that the authors requested have not yet arrived. Only a few papers were found in the open literature (journals or magazines). Although this report does not include all existing references, it provides an accurate assessment of efficient resins to be considered for waste minimization procedures. 70 refs.

Energy information directory 1997
The National Energy Information Center (NEIC), as part of its mission, provides energy information and referral assistance to Federal, state, and local governments, the academic community, business and industrial organizations, and the general public. The two principal functions related to this task are: (1) operating a general access telephone line, and (2) responding to energy-related correspondence addressed to the Energy Information Administration (EIA). The Energy Information Directory was developed to assist the NEIC staff, as well as other Department of Energy (DOE) staff, in directing inquiries to the proper offices within DOE, other Federal agencies, or energy-related trade associations. The Directory lists some of the Government offices and trade associations that are involved in energy matters. It includes those DOE offices which deal with the public or public information. For the purposes of this publication, each entry has been given a numeric identification symbol. The index found in the back of this publication uses these identification numbers to refer the reader to relevant entries.

Poisson type models and descriptive statistics of computer network information flows
Many contemporary publications on network traffic gravitate to ideas of self-similarity and long-range dependence. The corresponding elegant and parsimonious mathematical techniques proved to be efficient for the description of a wide class of aggregated processes. Sharing the enthusiasm about the above ideas the authors also believe that whenever it is possible any problem must be considered at the most basic level in an attempt to understand the driving forces of the processes under analysis. Consequently the authors try to show that some behavioral patterns of descriptive statistics which are typical for long-memory processes (a particular case of long-range dependence) can also be explained in the framework of the traditional Poisson process paradigm. Applying the concepts of inhomogeneity, compoundness and double stochasticity they propose a simple and intuitively transparent approach of explaining the expected shape of the observed histograms of counts and the expected behavior of the sample covariance functions. Matching the images of these two descriptive statistics allows them to infer the presence of trends or double stochasticity in analyzed time series. They considered only statistics which are based on counts. A similar approach may be applied to waiting or inter-arrival time sequences and will be discussed in other publications. …

High performance computing and communications: Advancing the frontiers of information technology
This report, which supplements the President`s Fiscal Year 1997 Budget, describes the interagency High Performance Computing and Communications (HPCC) Program. The HPCC Program will celebrate its fifth anniversary in October 1996 with an impressive array of accomplishments to its credit. Over its five-year history, the HPCC Program has focused on developing high performance computing and communications technologies that can be applied to computation-intensive applications. Major highlights for FY 1996: (1) High performance computing systems enable practical solutions to complex problems with accuracies not possible five years ago; (2) HPCC-funded research in very large scale networking techniques has been instrumental in the evolution of the Internet, which continues exponential growth in size, speed, and availability of information; (3) The combination of hardware capability measured in gigaflop/s, networking technology measured in gigabit/s, and new computational science techniques for modeling phenomena has demonstrated that very large scale accurate scientific calculations can be executed across heterogeneous parallel processing systems located thousands of miles apart; (4) Federal investments in HPCC software R and D support researchers who pioneered the development of parallel languages and compilers, high performance mathematical, engineering, and scientific libraries, and software tools--technologies that allow scientists to use powerful parallel systems to focus …

The Criticality Safety Information Resource Center at Los Alamos National Laboratory
The mission of the Criticality Safety Information Resource Center (CSIRC) at Los Alamos National Laboratory (LANL) is the preservation of primary documentation supporting criticality safety. In many cases, but not all, this primary documentation consists of experimentalists` logbooks. Experience has shown that the logbooks and other primary information are vulnerable to being discarded. Destruction of these logbooks results in a permanent loss to the criticality safety community.

Into the Woods: Wilderness Imagery as Representation of Spiritual and Emotional Transition in Medieval Literature
Wilderness landscape, a setting common in Romantic literature and painting, is generally overlooked in the art of the Middle Ages. While the medieval garden and the city are well mapped, the medieval wilderness remains relatively trackless. Yet the use of setting to represent interior experience may be traced back to the Neo-Platonic use of space and movement to define spiritual development. Separating themselves as far as possible from the material world, such writers as Origen and Plotinus avoided use of representational detail in their spatial models; however, both the visual artists and the authors who adopted the Neo-Platonic paradigm, elaborated their emotional spaces with the details of the classical locus amoenus and of the exegetical desert, while retaining the philosophical concern with spiritual transition. Analysis of wilderness as an image for spiritual and emotional transition in medieval literature and art relates the texts to an iconographic tradition which, along with motifs of city and garden, provides a spatial representation of interior progress, as the medieval dialectic process provides a paradigm for intellectual resolution. Such an analysis relates the motif to the core of medieval intellectual experience, and further suggests significant connections between medieval and modern narratives in regard to the …

Simulation of orthogonal cutting with smooth particle hydrodynamics
There is an active literature on the simulation of cutting processes through finite element methods. Such efforts are motivated by the enormous economic importance of machining processes and the desire to adjust processes so as to optimize product and throughput, but suffer from some difficulties inherent to the finite element method. An alternative approach, which appears to overcome most of those difficulties, is that of Smooth Particle Hydrodynamics (SPH).Though some finite element work is reviewed here, the focus of this paper is on the demonstration of the SPH technique of to simulate orthogonal cutting.

Science into art: A study of the creative process
Objective was to examine the creative process, demonstrated by 5 student participants in a class at the Art Center College of Design in Pasadena CA, from the germ of the creative idea through the final creative product. The students, drawn from classes sponsored by LLNL, were assigned the problem of representing ``big`` science, as practiced at LLNL, in a graphic, artistic, or multimedia product. As a result of this study, it was discovered that the process of creativity with these students was not linear in nature, nor did it strictly follow the traditional creativity 5-step schema of preparation, incubation, insight, evaluation, and elaboration. Of particular interest were several emergent themes of the creative process: spontaneous use of metaphor to describe the Laboratory; a general lack of interest in ``school`` science or mathematics by the American art students; a well developed sense of conscience; and finally, the symbolism inherent in the repeated use of a single artistic element. This use of the circle revealed a continuity of thinking and design perhaps related to the idealistic bias mentioned above.

An in-house alternative to traditional SDI services at Argonne National Laboratory
Selective Dissemination of Information (SDIs) are based on automated, well-defined programs that regularly produce precise, relevant bibliographic information. Librarians have typically turned to information vendors such as Dialog or STN international to design and implement these searches for their users in business, academia, and the science community. Because Argonne National Laboratory (ANL) purchases the Institute for Scientific Information (ISI) Current Contents tapes (all subject areas excluding Humanities). ANL scientists enjoy the benefit of in-house developments with BASISplus software programming and no longer need to turn to outside companies for reliable SDI service. The database and its customized services are known as ACCESS (Argonne Current Contents Electronic Search Service). Through collaboration with librarians on Boolean logic and selection of terms, users can now design their own personal profiles to comb the new data, thereby avoiding service fees from outside providers. Based on the feedback from scientists, it seems that this new service can help transform the ANL distributed libraries into more efficient central functioning entities that better serve the users. One goal is to eliminate the routing of paper copies of many new journal issues to different library locations for users to browse; instead users may be expected to rely more …
