Ontological Approaches For Semantic Interoperability, Michael A. Zang, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

This paper provides a basic description of the concept of an ontology. It then describes how ontologies are structured and employed in the context of interfaces between software based information systems. This usage is discussed in the context of three successive levels of semantic interoperability between two example systems. The paper goes on to suggest that the interfaces between information systems should perhaps be viewed and implemented as systems themselves. The paper concludes by providing a brief summary of what was discussed.

We report our analysis of the stability of pulsation periods in the DAV star (pulsating hydrogen atmosphere white dwarf) ZZ Ceti, also called R548. On the basis of observations that span 31 years, we conclude that the period 213. 13 s observed in ZZ Ceti drifts at a rate dP/dt ≤ (5.5 ± 1.9) × 10-15 s s-1, after correcting for proper motion. Our results are consistent with previous Ṗ values for this mode and an improvement over them because of the larger time base. The characteristic stability timescale implied for the pulsation period is | Ṗ / |≥ 1.2 …

Proceedings Of The 2003 Onr Decision-Support Workshop Series: Developing The New Infostructure, Collaborative Agent Design Research Center

Collaborative Agent Design (CAD) Research Center

In August of 1998 the Collaborative Agent Design Research Center (CADRC) of the California Polytechnic State University in San Luis Obispo (Cal Poly), approached Dr. Phillip Abraham of the Office of Naval Research (ONR) with the proposal for an annual workshop focusing on emerging concepts in decision-support systems for military applications. The proposal was considered timely by the ONR Logistics Program Office for at least two reasons. First, rapid advances in information systems technology over the past decade had produced distributed, collaborative computer-assistance capabilities with profound potential for providing meaningful support to military decision makers. Indeed, some systems based on …

Late Quaternary Lake-Level Changes Constrained By Radiocarbon And Stable Isotope Studies On Sediment Cores From Lake Titicaca, South America, Harold D. Rowe, Thomas P. Guilderson, Robert B. Dunbar, John R. Southon, Geoffrey O. Seltzer, David A. Mucciarone, Sherilyn C. Fritz, Paul A. Baker

Department of Earth and Atmospheric Sciences: Faculty Publications

We present and compare AMS-¹⁴C geochronologies for sediment cores recovered from Lake Titicaca, South America. Radiocarbon dates from three core sites constrain the timing of late Quaternary paleoenvironmental changes in the Central Andes and highlight the site-specific factors that limit the radiocarbon geochronometer. With the exception of mid-Holocene sediments, all cores are generally devoid of macrophyte fragments, thus bulk organic fractions are used to build core chronologies. Comparisons of radiocarbon results for chemically defined fractions (bulk decalcified, humate, humin) suggest that ages derived from all fractions are generally coherent in the post-13,500 yr BP time interval. In the …

A Varying-Coefficient Cox Model For The Effect Of Age At A Marker Event On Age At Menopause, Bin Nan, Xihong Lin, Lynda D. Lisabeth, Sioban D. Harlow

The University of Michigan Department of Biostatistics Working Paper Series

. It is of recent interest in reproductive health research to investigate the validity of a marker event for the onset of menopausal transition and to estimate age at menopause using age at the marker event. We propose a varying coefficient Cox model to investigate the association between age at a marker event, denned as a specific bleeding pattern change, and age at menopause, where both events are subject to censoring and their association varies with age at the marker event. Estimation proceeds using the regression spline method. The proposed method is applied to the Tremin Trust Data to evaluate …

Seismcity In The Vicinity Of Yucca Mountain, Nevada, For The Period October 1, 2000 To September 30, 2001, David H. Von Seggern, Kenneth Smith, James N. Brune, Richard Quittmeyer, Amy J. Smiecinski

Publications (YM)

Starting on October 1, 1995, the monitoring of seismicity within the southern Great Basin near Yucca Mountain was performed with a new digital network. This network features three-component recording with 24-bit A/D conversion in the field. Continuous data are collected at 20 sps, and event triggered windows are collected at 100 sps. A seismic bulletin of events is made by automatically associating triggers among stations, classifying the local earthquake events, and locating the earthquakes and computing their magnitudes with conventional methods. This report covers the operational and seismic results of the sixth full year (FY01) of the improved, digitally based, …

A Family Affair: Sharing Information About Genetic Diseases, Lyria K. Bennett Moses

ExpressO

Genetic test results provide information relevant to the future health of the person tested as well as parents, siblings, children and more distant relatives. This Article examines the legal consequences that might follow a decision to share or withhold genetic information. It argues that the obstacles to liability might not be justified in situations where either disclosure of genetic information or silence will cause significant harm.

Nanocomposite (Nd,Dy)(Fe,Co,Nb,B) 5.5/Α-Fe Multilayer Magnets With High Performance, W. Liu, Z.D. Zhang, J. Ping Liu

David Sellmyer Publications

The structural and magnetic properties of rare-earth nanocomposite magnets of a (Nd,Dy)(Fe,Co,Nb,B) _5.5 single layer and a (Nd,Dy)(Fe,Co,Nb,B) _5.5/α-Fe multilayer prepared by sputtering and heat treatment have been investigated. Incomplete exchange coupling behaviour is observed in the Ti-buffered NdDyFeCoNbB + 40 wt%Fe single layer magnet. After annealing, the laminated nanostructure consisting of mutually dispersed soft and hard phases results in remanence enhancement. The optimum magnetic properties of J_r= 1.11 T, μ_0i H_c = 0.88 T and (BH)max = 192 kJ m^-3 are achieved in the multilayer magnet annealed at 550°C for 30 min. …

Are They Really Teachers? Problem-Based Learning And Information Professionals, Michael Anderson, Virginia Baldwin

University of Nebraska-Lincoln Libraries: Faculty Publications

Traditionally, working with teaching faculty is the primary consulting role for most faculty development professionals. The boundaries, however, are not always clear regarding instructional assistance that is provided to other personnel. This chapter demonstrates how collaboration among faculty consultants and information specialists can result in enhanced library utilization and bett er research-related instruction. Our model uses problem-based learning (PEL) as a vehicle for teaching research and retrieval skills in either a single class experience or in multiple classroom visits with an engineering librarian.

Computer Literacy: Necessity Or Buzzword?, Scott Childers

University of Nebraska-Lincoln Libraries: Faculty Publications

While the concept of computer literacy has existed for some time, the name has certainly changed. Whatever the name, the concept of computer literacy still has merit. By looking at the history of the computer literacy movement for grounding, we can build a definition for the next century and affirm that learning computer basics is a good thing for library staff to do.

The term computer literacy seems to have faded from library literature, but has the belief that the general populace should possess a basic computer-skill level faded as well? Have we already achieved this nebulous goal, or has …

A Stochastic Sediment Delivery Model For A Steep Mediterranean Landscape, Emmanuel Gabet, Thomas Dunne

Faculty Publications

It is a truism in geomorphology that climatic events operate on a landscape to drive sediment transport processes, yet few investigations have formally linked climate and terrain characteristics with geomorphological processes. In this study, we incorporate sediment transport equations derived from fieldwork into a computer model that predicts the delivery of sediment from hillslopes in a steep Mediterranean landscape near Santa Barbara, California. The sediment transport equations are driven by rainstorms and fires that are stochastically generated from probability distributions. The model is used to compare the rates and processes of sediment delivery under two vegetation types: coastal sage scrub …

Index Selection For Embedded Control Applications Using Description Logics, Lubomir Stanchev, Grant Weddell

Computer Science and Software Engineering

We consider the problem of automated index selection for embedded control programs (ECPs). Such systems have the property that the transaction types, which can consist of queries and updates, are predefined and can be classified as either critical or non-critical. In this paper, we focus on the critical part of the transaction workload for ECPs. More precisely, our problem input consists of a set of critical transaction types and a database schema. The goal is to find a minimum number of extended indices that enable every critical operation to be performed efficiently. The proposed solution is novel in that it …
