A Framework For Processing Complex Document-Centric Xml With Overlapping Structures, Ionut E. Iacob, Alex Dekhtyar
A Framework For Processing Complex Document-Centric Xml With Overlapping Structures, Ionut E. Iacob, Alex Dekhtyar
Computer Science and Software Engineering
Management of multihierarchical XML encodings has attracted attention of a number of researchers both in databases [8] and in humanities[10]. Encoding documents using multiple hierarchies can yield overlapping markup. Previously proposed solutions to management of document-centric XML with overlapping markup rely on the XML expertise of humans and their ability to maintain correct schemas for complex markup languages.
We demonstrate a unified solution for management of complex, multihierarchical document-centric XML. Our framework includes software for storing, parsing, in-memory access, editing and querying, multihierarchical XML documents with conflicting structures.

Processing Xml Documents With Overlapping Hierarchies, Ionut E. Iacob, Alex Dekhtyar
Computer Science and Software Engineering
The problem of overlapping markup hierarchies, first mentioned in the context of SGML, often occurs in XML text encoding applications for humanities. Previous solutions to the problem rely on manual maintenance of the markup and address only the problem of representing overlapping features in XML, leaving the issues of automated maintenance and querying open. As a consequence, traditional XML tools are of little practical use when dealing with overlapping markup. In this work we demonstrate the implementation of our framework for management of concurrent XML hierarchies from a computer science perspective. We propose an underlying model, data structures, APIs, and …

Ga-Facilitated Classifier Optimization With Varying Similarity Measures, Michael R. Peterson, Travis E. Doom, Michael L. Raymer
Ga-Facilitated Classifier Optimization With Varying Similarity Measures, Michael R. Peterson, Travis E. Doom, Michael L. Raymer
Kno.e.sis Publications
Genetic algorithms are powerful tools for k-nearest neighbors classification. Traditional knn classifiers employ Euclidian distance to assess neighbor similarity, though other measures may also be used. GAs can search for optimal linear weights of features to improve knn performance using both Euclidian distance and cosine similarity. GAs also optimize additive feature offsets in search of an optimal point of reference for assessing angular similarity using the cosine measure. This poster explores weight and offset optimization for knn with varying similarity measures, including Euclidian distance (weights only), cosine similarity, and Pearson correlation. The use of offset optimization …

Crossover From Kramers To Phase-Diffusion Switching In Moderately Damped Josephson Junctions, Jaan Männik, S. Li, W. Qiu, W. Chen, V. Patel, S. Han, J. E. Lukens
Crossover From Kramers To Phase-Diffusion Switching In Moderately Damped Josephson Junctions, Jaan Männik, S. Li, W. Qiu, W. Chen, V. Patel, S. Han, J. E. Lukens
Jaan Männik
We have measured and propose a model for switching rates in a hysteretic dc superconducting quantum interference device (SQUID) in the regime where phase-diffusion processes start to occur. We show that the switching rates in this regime are smaller than the rates given by Kramers’ formula due to retrapping of the Josephson phase. The retrapping process, which is affected by the frequency dependent impedance of the environment of the dc SQUID, leads to a peaked second moment of the switching distribution as a function of temperature. The temperatures where the peaks occur are proportional to the critical current of the …

Sensing Of Antipyretic Carboxylates By Simple Chromogenic Calix[4]Pyrroles, Ryuhei Nishiyabu, Pavel Anzenbacher Jr.
Chemistry Faculty Publications
We present a simple, two- or three-step method for the synthesis of chromogenic octamethylcalix[4]pyrrole-based (OMCP) sensors for anions. Electrophilic aromatic substitution allows for converting the pyrrole moieties of OMCP into a dye. The formation of a sensor-anion complex results in partial charge transfer and a dramatic change in color. The absorption (UV-vis) and NMR titration experiments show that the chromogenic OMCPs sense anions administered as aqueous solutions, even at high ionic strength ( approximately 0.1 M NaCl), while displaying selectivity for pyrophosphate and carboxylate anions. The experiments with polyurethane sensor films show a strong response for aqueous carboxylates, such as …
Microgravity Studies Of Aggregation In Particulate Clouds, Todd B. Sauke, J. R. Marshall, J. N. Cuzzi
Microgravity Studies Of Aggregation In Particulate Clouds, Todd B. Sauke, J. R. Marshall, J. N. Cuzzi
Faculty Publications
Aggregation in clouds of submillimeter quartz and volcanic ash particles was studied in microgravity. Particle clouds generated by pulses of air immediately formed electrostatic filamentary aggregates upon cessation of air turbulence. Manual agitation of experiment chambers produced cm-size loose grain clusters which voraciously scavenged free-floating material in their vicinity. A dipole model accounts for these observations. Experimental results have ramifications for the behavior of natural cloud systems and primary accretion of solids in the early solar nebula.

Description Logic Programs: A Practical Choice For The Modelling Of Ontologies, Rudi Studer, York Sure, Pascal Hitzler
Description Logic Programs: A Practical Choice For The Modelling Of Ontologies, Rudi Studer, York Sure, Pascal Hitzler
Computer Science and Engineering Faculty Publications
Knowledge representation using ontologies constitutes the heart of semantic technologies. Despite successful standardization efforts by the W3C, however, there are still numerous different ontology representation languages being used, and interoperability between them is in general not given. The problem is aggrevated by the fact that current standards lay foundations only and are well-known to be insufficient for the modelling of finer details. Thus, a plethora of extensions of the basic languages is being proposed, rendering the picture of ontology representation languages to be chaotic, to say the least. While semantic technologies start to become applicable and are being applied in …
Towards A Systematic Account Of Different Semantics For Logic Programs, Pascal Hitzler
Towards A Systematic Account Of Different Semantics For Logic Programs, Pascal Hitzler
Computer Science and Engineering Faculty Publications
A new methodology has been proposed which allows one to derive uniform characterizations of different declarative semantics for logic programs with negation. One result from this work is that the well-founded semantics can formally be understood as a stratified version of the Fitting (or Kripke–Kleene) semantics. The constructions leading to this result, however, show a certain asymmetry which is not readily understood. We study this situation here with the result that we obtain a coherent picture of relations between different semantics for normal logic programs.

Scene-Based Nonuniformity Correction Technique For Focal-Plane Arrays Using Readout Architecture, Balaji Narayanan, Russell C. Hardie, Robert A. Muse
Scene-Based Nonuniformity Correction Technique For Focal-Plane Arrays Using Readout Architecture, Balaji Narayanan, Russell C. Hardie, Robert A. Muse
Electrical and Computer Engineering Faculty Publications
Spatial fixed pattern noise is a common and major problem in modern infrared imagers due to the nonuniform response of the photodiodes in the focal plane array of the imaging system. In addition, the nonuniform response of the readout and the digitization electronics, involved in multiplexing the signals from the photodiodes, causes further nonuniformity. In this paper, we describe a novel scene based nonuniformity correction algorithm that treats the aggregate nonuniformity in separate stages. Firstly, the nonuniformity from the readout amplifiers is corrected using knowledge of the readout architecture of the imaging system. In the second stage, the nonuniformity resulting …

Eleven New Γ Doradus Stars, Gregory W. Henry, Francis C. Fekel, Stephen M. Henry
Information Systems and Engineering Management Research Publications
We present new high-dispersion spectroscopic and precise photometric observations to identify 11 new γ Doradus variables. Seven of these new γ Doradus stars appear to be single, three are primaries of single-lined binaries, and one has two distant visual companions; none are double-lined or close visual binaries. Several of the stars show spectroscopic line-profile and low-amplitude radial velocity variability indicative of pulsation. All 11 stars are photometrically variable with amplitudes between 8 and 93 mmag in Johnson B and periods between 0.398 and 2.454 days. One star is monoperiodic; the rest have between two and five independent periods. The variability …
Structure And Stability Of Mott-Insulator Shells Of Bosons Trapped In An Optical Lattice, B. Demarco, Courtney Lannert, S. Vishveshwara, T. C. Wei
Structure And Stability Of Mott-Insulator Shells Of Bosons Trapped In An Optical Lattice, B. Demarco, Courtney Lannert, S. Vishveshwara, T. C. Wei
Physics: Faculty Publications
We consider the feasibility of creating a phase of neutral bosonic atoms in which multiple Mott-insulating states coexist in a shell structure and propose an experiment to spatially resolve such a structure. This spatially inhomogeneous phase of bosons, arising from the interplay between the confining potential and the short-ranged repulsion, has been previously predicted. While the Mott-insulator phase has been observed in an atomic gas, the spatial structure of this phase in the presence of an inhomogeneous potential has not yet been directly probed. In this paper, we give a simple recipe for creating a structure with any desired number …

Chemistry
Fluorescence-dip infrared spectroscopy, an UV-IR double-resonance technique, is employed to characterize the line positions, linewidths, and corresponding lifetimes of highly predissociative rovibrational levels of the excited A electronic state of the OH radical. Various lines of the 4←2 overtone transition in the excited A state are observed, from which the rotational, centrifugal distortion, and spin-rotation constants for the A (v = 4) state are determined, along with the vibrational frequency for the overtone transition. Homogeneous linewidths of 0.23–0.31 cm−1 full width at half maximum are extracted from the line profiles, demonstrating that the N = …

Design And Preliminary Results Of A Prototype Hts Smes Device, Christopher J. Hawley, S. A. Gower
Faculty of Informatics - Papers (Archive)
The University of Wollongong (UOW) has developed the design for a 20 kJ high transition temperature Superconducting Magnetic Energy Storage (SMES) device, and constructed a nominally 2.5 kJ prototype. The coil for the prototype was wound using High Temperature Superconducting (HTS) BSCCO-2223 tape. It was refrigerated to 20 K using a gaseous helium cold head cryocooler. The SMES device has been constructed as a prototype for a larger commercially realizable system, and hence is capable of supplying a 3-phase load during voltage sags or short (s) power interruptions. This paper discusses the modeling and design of the electromagnetic and thermal …
