Characterization Of Mantle/Crust Interactions Using Pb Isotope Analyses Of Lavas In The Southern Rio Grande Rift, New Mexico, Lynnette Crocker 2010 University of Texas at El Paso

Characterization Of Mantle/Crust Interactions Using Pb Isotope Analyses Of Lavas In The Southern Rio Grande Rift, New Mexico, Lynnette Crocker

Open Access Theses & Dissertations

The Pb isotope composition of volcanic rocks in the Rio Grande Rift (RGR) can be used to investigate the interaction of mantle melts with continental lithosphere, and has important implications for the composition of the lithosphere. We suggest some compositional signatures may pre-date current tectonic processes. Existing data from several volcanic fields in New Mexico show a converging pattern on a very limited Pb isotope range, corresponding to lower crustal xenolith compositions from Kilbourne Hole. The different volcanic fields show Pb isotope trends diverging from this lower crustal composition, likely depicting mixing with different upper crustal reservoirs. These very common ...


Paleotsunami Inundation Of A Beach Ridge Plain: Cobble Ridge Overtopping And Interridge Valley Flooding In Seaside, Oregon, Usa, Curt D. Peterson, Harry M. Jol, Thomas Horning, Kenneth M. Cruikshank 2010 Portland State University

Paleotsunami Inundation Of A Beach Ridge Plain: Cobble Ridge Overtopping And Interridge Valley Flooding In Seaside, Oregon, Usa, Curt D. Peterson, Harry M. Jol, Thomas Horning, Kenneth M. Cruikshank

Geology Faculty Publications and Presentations

The Seaside beach ridge plain was inundated by six paleotsunamis during the last ∼2500 years. Large runups (adjusted >10m in height) overtopped seawardmost cobble beach ridges (7m elevation) at ∼1.3 and ∼2.6 ka before present. Smaller paleotsunami (6−8m in height) likely entered the beach plain interior (4-5m elevation) through the paleo-Necanicum bay mouth. The AD 1700 Cascadia paleotsunami had a modest runup (6-7mheight), yet it locally inundated to 1.5 km landward distance. Bed shear stresses (100−3,300 dyne cm−2) are estimated for paleotsunami surges (0.5−2m depths) that flowed down slopes (0.002 ...


Local Out-Tournaments With Upset Tournament Strong Components I: Full And Equal {0,1}-Matrix Ranks, Kim A. S. Factor, Rebecca M. Kohler, Jason M. Derby 2010 Marquette University

Local Out-Tournaments With Upset Tournament Strong Components I: Full And Equal {0,1}-Matrix Ranks, Kim A. S. Factor, Rebecca M. Kohler, Jason M. Derby

Mathematics, Statistics and Computer Science Faculty Research and Publications

A digraph D is a local out-tournament if the outset of every vertex is a tournament. Here, we use local out-tournaments, whose strong components are upset tournaments, to explore the corresponding ranks of the adjacency matrices. Of specific interest is the out-tournament whose adjacency matrix has boolean, nonnegative integer, term, and real rank all equal to the number of vertices, n. Corresponding results for biclique covers and partitions of the digraph are provided.


Digraphs With Isomorphic Underlying And Domination Graphs: Pairs Of Paths, Kim A. S. Factor, Larry J. Langley 2010 Marquette University

Digraphs With Isomorphic Underlying And Domination Graphs: Pairs Of Paths, Kim A. S. Factor, Larry J. Langley

Mathematics, Statistics and Computer Science Faculty Research and Publications

A domination graph of a digraph D, dom (D), is created using thc vertex set of D and edge uv ϵ E (dom (D)) whenever (u, z) ϵ A (D) or (v, z) ϵ A (D) for any other vertex z ϵ A (D). Here, we consider directed graphs whose underlying graphs are isomorphic to their domination graphs. Specifically, digraphs are completely characterized where UGc (D) is the union of two disjoint paths.

Gamma-rays at MeV energies provide a unique window on the high energy Universe, especially so for nuclear astrophysics. The potential for significant contributions, e.g., to the understanding of SNe Ia as well as the large potential for new discoveries has long been recognized, but technical progress in this challenging energy band has been slow. The groundbreaking discoveries of CGRO’s COMPTEL, however, have inspired and driven the development of powerful new instrumentation over the past decade. Novel detector technologies developed in the US and Japan enable compact Compton telescopes, greatly improving the efficiency and field-of-view achievable with this technique ...

Over the next decade, we can expect time domain astronomy to flourish at optical and radio wavelengths. In parallel with these efforts, a dedicated transient "machine" operating at higher energies (X-ray band through soft gamma-rays) is required to reveal the unique subset of events with variable emission predominantly visible above 100 eV. Here we focus on the transient phase space never yet sampled due to the lack of a sensitive, wide-field and triggering facility dedicated exclusively to catching high energy transients and enabling rapid coordinated multi-wavelength follow-up. We first describe the advancements in our understanding of known X-ray transients that ...

Publications

GRB 080913 and GRB 090423 are the most distant gamma-ray bursts (GRBs) known to date, with spectroscop-ically determined redshifts of z = 6.7 and z = 8.1, respectively. The detection of bursts at this early epoch of the universe significantly constrains the nature of GRBs and their progenitors. We perform population synthesis studies of the formation and evolution of early stars, and calculate the resulting formation rates of short- and long-duration GRBs at high redshift. The peak of the GRB rate from Population II stars occurs at z ∼ 7for a model with efficient/fast mixing of metals, while it is ...


Information Sharing Across Private Databases, Swapnil Suresh Samant 2010 University of Texas at El Paso

Information Sharing Across Private Databases, Swapnil Suresh Samant

Open Access Theses & Dissertations

While the explosion of availability of information has become invaluable in modern society, it has also raised valid concerns about erosion of privacy. More and more, different entities are encouraged to share information in order to discover potential security risks, health pattern, or social behavior trends. However, some of this information is sensitive. Owners of information may be unwilling to share their whole databases with other entities, either to protect the privacy of the records, or because of the proprietary nature of the information.

We consider the following problem. How can we compute the intersection and the equijoin of databases ...


Tectonic Geomorphology Of The Puna Tsang Chhu, Western Bhutan, Abby May Woody 2010 University of Texas at El Paso

Tectonic Geomorphology Of The Puna Tsang Chhu, Western Bhutan, Abby May Woody

Open Access Theses & Dissertations

There are two boundaries, or physiographic transitions, between three distinct topographic regions in Bhutan. The southern and northern regions have relatively steep hillslopes and high relief, while the central region has gentle hillslopes and low relief. The geomorphology of a 70-km stretch along the Puna Tsang Chhu valley between the towns of Uma and Amrimo was studied in March and April of 2009 to provide constraints on the active tectonics of western Bhutan and the nature of these physiographic transitions.

The Puna Tsang Chhu valley contains a set of alluvial cut-and-fill and bedrock (strath) river terraces with associated sediments - younger ...

Bauer alkylamide 11 and Bauer ketone 23 were previously found to be partially responsible forEchinacea angustifolia anti-inflammatory properties. This study further tested their importance using the inhibition of prostaglandin E2 (PGE2) and nitric oxide (NO) production by RAW264.7 mouse macrophages in the absence and presence of lipopolysaccharide (LPS) and E. angustifolia extracts, phytochemical enriched fractions, or pure synthesized standards. Molecular targets were probed using microarray, qRT-PCR, Western blot, and enzyme assays. Fractions with these phytochemicals were more potent inhibitors of LPS-induced PGE2 production than E. angustifolia extracts. Microarray did not detect changes in transcripts with ...

Mandates aside, there are many reasons why firms decide to move forward with or delay investment in RFID technology. In this paper we use a theoretically based, easy to implement methodology to empirically derive a relative importance scale of those factors that influence the decision to invest in RFID technology. More specifically, we compare the factors that matter most and least to a sample of firms that have adopted RFID technology with a sample of firms that have yet to embrace RFID technology. The theoretical and practical implications are that both RFID adopters and non adopters are driven by the ...


Head-Tracking Haptic Computer Interface For The Blind, Simon Meers, Koren Ward 2010 University of Wollongong

Head-Tracking Haptic Computer Interface For The Blind, Simon Meers, Koren Ward

Faculty of Informatics - Papers (Archive)

In today’s heavily technology-dependent society, blind and visually impaired people are becoming increasingly disadvantaged in terms of access to media, information, electronic commerce, communications and social networks. Not only are computers becoming more widely used in general, but their dependence on visual output is increasing, extending the technology further out of reach for those without sight. For example, blindness was less of an obstacle for programmers when command-line interfaces were more commonplace, but with the introduction of Graphical User Interfaces (GUIs) for both development and final applications, many blind programmers were made redundant (Alexander, 1998; Siegfried et al., 2004 ...

This report describes the choice of the preliminary design for the New Zealand Health Survey, to be implemented from 2011. The survey will use computer assisted personal interviewing. The sample will be selected using a multi-stage area design. The selected sample size will be around 12,000 people per year. This is envisaged as sufficient to provide adequate precision for estimates of key prevalences for adults and children. The main objectives of the sample design are: • The design should support analysis of the survey by multiple users, which implies avoiding great variation in estimation weights. • Estimates for children and adults ...

Realigning Service Operations Strategy At Dhl Express, Tim R. Coltman, John Gattorna, Stuart Whiting

Faculty of Informatics - Papers (Archive)

This paper describes the approach that DHL used to respond to aggressive revenue and profit targets set by its Asia-Pacific regional management board. DHL’s reaction to these targets was to redefine its strategic service vision by systematically aligning its internal support functions with distinct buyer behavior structures. Specifically, we developed a model based on the tangible and intangible factors that directly influence a customer’s choice of a third-party logistics provider. Next, we reverse engineered the service provider’s delivery system to align with each customer’s preferred buying behavior. DHL’s share of wallet and profitability immediately improved ...


Business Relationships In China: Lessons About Deep Trust, A. Kriz, Byron W. Keating 2010 University of Newcastle

Business Relationships In China: Lessons About Deep Trust, A. Kriz, Byron W. Keating

Faculty of Informatics - Papers (Archive)

Trust is acknowledged as a central tenet of business relationships. Yet for all the attention it receives, rarely has trust been investigated in the Chinese business setting. This paper uses an emic approach to unearth some within- culture ‘truths’ about Chinese notions of trust in business exchange. The findings of this research suggest that deep trust (xinren), which is driven by reciprocal help and emotional bonding, is critical for doing business in China. A conceptual framework is provided to assist Western businesspersons to better understand the Chinese concept of trust as well as the interplay between its key antecedents.


Efficient Svm Training With Reduced Weighted Samples, Son Lam Phung, Giang Hoang Nguyen, Abdesselam Bouzerdoum 2010 University of Wollongong

Efficient Svm Training With Reduced Weighted Samples, Son Lam Phung, Giang Hoang Nguyen, Abdesselam Bouzerdoum

Faculty of Informatics - Papers (Archive)

This paper presents an efficient training approach for support vector machines that will improve their ability to learn from a large or imbalanced data set. Given an original training set, the proposed approach applies unsupervised learning to extract a smaller set of salient training exemplars, which are represented by weighted cluster centers and the target outputs. In subsequent supervised learning, the objective function is modified by introducing a weight for each new training sample and the corresponding penalty term. In this paper, we investigate two methods of defining the weight based on cluster vectors. The proposed SVM training is implemented ...


A Particle Swarm Optimization Algorithm Based On Orthogonal Design, Jie Yang, Abdesselam Bouzerdoum, Son Lam Phung 2010 University of Wollongong

A Particle Swarm Optimization Algorithm Based On Orthogonal Design, Jie Yang, Abdesselam Bouzerdoum, Son Lam Phung

Faculty of Informatics - Papers (Archive)

The last decade has witnessed a great interest in using evolutionary algorithms, such as genetic algorithms, evolutionary strategies and particle swarm optimization (PSO), for multivariate optimization. This paper presents a hybrid algorithm for searching a complex domain space, by combining the PSO and orthogonal design. In the standard PSO, each particle focuses only on the error propagated back from the best particle, without “communicating” with other particles. In our approach, this limitation of the standard PSO is overcome by using a novel crossover operator based on orthogonal design. Furthermore, instead of the “generating-and-updating” model in the standard PSO, the elitism ...


Dimensionality Reduction Using Compressed Sensing And Its Application To A Large-Scale Visual Recognition Task, Son Lam Phung, Fok Hing Chi Tivive, Abdesselam Bouzerdoum, Jie Yang 2010 University of Wollongong

Dimensionality Reduction Using Compressed Sensing And Its Application To A Large-Scale Visual Recognition Task, Son Lam Phung, Fok Hing Chi Tivive, Abdesselam Bouzerdoum, Jie Yang

Faculty of Informatics - Papers (Archive)

This paper presents a novel algorithm for the dimensionality reduction which employs compressed sensing (CS) to improve the generalization capability of a classifier, especially for large-scale data. Compared to traditional dimensionality reduction methods, the proposed algorithm makes no use of the problem-dependent parameters, nor does it require additional computation for the eigenvalue decomposition like PCA or LDA. Mathematically, the derived algorithm regards the input features as the dictionary in CS, and selects the features that minimize the residual output error iteratively, thus the resulting features have a direct correspondence to the performance requirements of the given problem. Furthermore, the proposed ...
