Rich Mesic Forests: Edaphic And Physiographic Drivers Of Community Variation In Western Massachusetts, J. Bellemare, G. Motzkin, D. R. Foster Jan 2005

Rich Mesic Forests: Edaphic And Physiographic Drivers Of Community Variation In Western Massachusetts, J. Bellemare, G. Motzkin, D. R. Foster

Biological Sciences: Faculty Publications

Rich Mesic Forest, a Northeastern variant of the species-rich Mixed Mesophytic Forest association of eastern North America, is an Acer saccharum-dominated forest type typically associated with calcareous bedrock and nutrient-rich, mull soils. Rich Mesic Forest (RMF) is a priority for conservation in the Northeast due to its limited areal extent, high plant species richness, and numerous rare taxa, yet the community characteristics and environmental correlates of this forest type are incompletely understood. This study undertook a quantitative classification of RMF of the northeastern edge of the Berkshire Plateau in western Massachusetts. Cluster analysis of data from ten sites identified two …

Associative Structures Based Upon A Categorical Braiding, Stefan Forcey Jan 2005

Associative Structures Based Upon A Categorical Braiding, Stefan Forcey

Mathematical Sciences Faculty Research

It is well known that the existence of a braiding in a monoidal category V allows many structures to be built upon that foundation. These include a monoidal 2-category V-Cat of enriched categories and functors over V, a monoidal bicategory V-Mod of enriched categories and modules, a category of operads in V and a 2-fold monoidal category structure on V. We will begin by focusing our exposition on the first and last in this list due to their ability to shed light on a new question. We ask, given a braiding on V, what non-equal structures of a given kind …

Highway 12, Christian Probasco Jan 2005

Highway 12, Christian Probasco

All USU Press Publications

Highway 12 is undoubtedly one of not only America's but the world's most scenic highways. From its intersection on the west with Highway 89 south of Panguitch, Utah, it runs up through Red Canyon onto the Paunsagunt Plateau and across Bryce Canyon National Park. It then drops into the Paria River Valley, passes through several tiny villages, crosses some extraordinary (for anywhere but this region) badlands, and descends the Escalante River into Potato Valley. While a driver may justifiably feel she has seen some scenery by that point, the highway is just getting started, for in the next stretch, it …

High, Wide, And Handsome: The River Journals Of Norman D. Nevills, Roy Webb Jan 2005

High, Wide, And Handsome: The River Journals Of Norman D. Nevills, Roy Webb

All USU Press Publications

When he started taking paying passengers by boat through the rapids of the Colorado River's canyons, Norman Nevills invented whitewater tourism and the commercial river business. For twelve years, from 1938 until his death in a plane crash in 1949, he safely took, without a single life lost, friends, explorers, and customers down the Colorado, Green, San Juan, Salmon, and Snake Rivers in boats he designed. National media found him and his adventures irresistible and turned him into the personification of river running. Logging seven trips through the Grand Canyon when no one else had completed more than two, he …

Physics & Astronomy

[1] A plasmoid-like structure without a core magnetic field has been observed by Cluster spacecraft in the high latitude magnetopause region when the interplanetary magnetic field (IMF) is northward and has a dominant duskward component. Bursty electrons and ions are found to be well confined in this plasmoid-like structure. The structure possesses a bipolar signature in the BN component. The structure is associated with a dramatic change of the plasma flow direction from tailward to dawnward. The plasma density in this structure is slightly enhanced whereas the ion temperature is twice as large as that of the ambient plasma. The …

Computer-Supported Rehabilitation Management A Case Study Of Using Virtual Reality Technology In Ambulatory Training For Post-Acute Stroke Patients, Felix O. Akinladejo Jan 2005

Computer-Supported Rehabilitation Management A Case Study Of Using Virtual Reality Technology In Ambulatory Training For Post-Acute Stroke Patients, Felix O. Akinladejo

CCE Theses and Dissertations

This study investigated the use of virtual reality (VR) technology in ambulatory training for post-acute stroke patients, and sought to determine whether skills gained in virtual environments transfer to real-world conditions. Patients with stroke typically suffer dysfunctions that impair the complex set of motions involved in walking. The limited amount of therapy and resources offered by the current health care system does not provide the frequency and intensity of training needed for functional recovery of the walking skills in patients following stroke assaults. This study, therefore, developed and investigated an alternative intervention technique capable of providing the frequency and intensity …

Continued Studies Of Single-Sided Charge-Sharing Czt Strip Detectors, B Donmez, John R. Macri, Mark L. Mcconnell, James M. Ryan, Mark Widholm, L A. Hamel, T Narita

Space Science Center

In this paper, we report progress in the study of thick single-sided charge-sharing cadmium zinc telluride (CZT) strip detector modules designed to perform gammaray spectroscopy and 3-D imaging. We report on continuing laboratory and simulation measurements of prototype detectors with 11×11 unit cells (15×15×7.5mm3 ). We report preliminary measurements of the 3-D spatial resolution. Our studies are aimed at developing compact, efficient, detector modules for 0.05 to 1 MeV gamma measurements while minimizing the number and complexity of the electronic readout channels. This is particularly important in space-based coded aperture and Compton telescope instruments that require large area, large volume …

Development Of The Fast Neutron Imaging Telescope, U Bravar, P J. Bruillard, E O. Fluckiger, John R. Macri, A L. Mackinnon, Mark L. Mcconnell, M R. Moser, James M. Ryan, R S. Woolf Jan 2005

Development Of The Fast Neutron Imaging Telescope, U Bravar, P J. Bruillard, E O. Fluckiger, John R. Macri, A L. Mackinnon, Mark L. Mcconnell, M R. Moser, James M. Ryan, R S. Woolf

Space Science Center

We report on the development of a next generation neutron telescope, with imaging and energy measurement capabilities, sensitive to neutrons in the 2-20 MeV energy range. The Fast Neutron Imaging Telescope (FNIT) was initially conceived to study solar neutrons as a candidate instrument for the Inner Heliosphere Sentinels (IHS) program under formulation at NASA. This detector is now being adapted to locate Special Nuclear Material (SNM) for homeland security purposes by detecting fission neutrons and reconstructing the image of their source. In either case, the detection principle is based on multiple elastic neutron-proton scatterings in organic scintillator. By reconstructing the …

A Hard X-Ray Polarimeter Designed For Transient Astrophysical Sources, Mark L. Mcconnell, Peter F. Bloser, Jason S. Legere, John R. Macri, T Narita Jan 2005

A Hard X-Ray Polarimeter Designed For Transient Astrophysical Sources, Mark L. Mcconnell, Peter F. Bloser, Jason S. Legere, John R. Macri, T Narita

Space Science Center

— This paper discusses the latest progress in the development of GRAPE (Gamma-Ray Polarimeter Experiment), a hard X-ray Compton Polarimeter. The purpose of GRAPE is to measure the polarization of hard X-rays in the 50-300 keV energy range. We are particularly interested in X-rays that are emitted from solar flares and gamma-ray bursts (GRBs). Accurately measuring the polarization of the emitted radiation from these sources will lead, to a better understating of both the emission mechanisms and source geometries. The GRAPE design consists of an array of plastic scintillators surrounding a central high-Z crystal scintillator. We can monitor individual Compton …

On The Optimization Of Visualizations Of Complex Phenomena, Donald H. House, Althea D. Bair, Colin Ware Jan 2005

On The Optimization Of Visualizations Of Complex Phenomena, Donald H. House, Althea D. Bair, Colin Ware

Center for Coastal and Ocean Mapping

The problem of perceptually optimizing complex visualizations is a difficult one, involving perceptual as well as aesthetic issues. In our experience, controlled experiments are quite limited in their ability to uncover interrelationships among visualization parameters, and thus may not be the most useful way to develop rules-of-thumb or theory to guide the production of high-quality visualizations. In this paper, we propose a new experimental approach to optimizing visualization quality that integrates some of the strong points of controlled experiments with methods more suited to investigating complex highly-coupled phenomena. We use human-in-the-loop experiments to search through visualization parameter space, generating large …

A Closed-Form Exact Solution For The Value Of American Put And Its Optimal Exercise Boundary, Song-Ping Zhu Jan 2005

A Closed-Form Exact Solution For The Value Of American Put And Its Optimal Exercise Boundary, Song-Ping Zhu

Faculty of Informatics - Papers (Archive)

Searching for a closed-form exact solution for American put options under the Black-Scholes framework has been a long standing problem in the past; many researchers believe that it is impossible to find such a solution. In this paper, a closed-form exact solution, in the form of a Taylor's series expansion, of the well-known Black-Scholes equation is presented for the first time. As a result of this analytic solution, the optimal exercise boundary, which is the main difficulty of the problem, is found as an explicit function of the risk-free interest rate, the volatility and the time to expiration.

Development Of Empirical Relationships For Metallurgical Design Of Hot-Rolled Steel Products, Timothy R. Marchant, Alysha Nickerson, David Scott, Steve Taylor Jan 2005

Development Of Empirical Relationships For Metallurgical Design Of Hot-Rolled Steel Products, Timothy R. Marchant, Alysha Nickerson, David Scott, Steve Taylor

Faculty of Informatics - Papers (Archive)

An empirical model is developed to predict the mechanical properties that steel inherits from the hot-rolling process and its chemical composition. In this process, slabs of steel are heated and rolled into thinner sheets which are either coiled or cut into plates. The mechanical properties of the coils and plates are sampled and must conform to national and international standards for steel products. The aim here is to use the statistical technique of multiple linear regression to develop relationships between the mechanical properties and the various processing temperatures and concentrations of chemical elements present in the steel. This analytical tool …

Bifurcation Phenomena For An Oxidation Reaction In A Continuously Stirred Tank Reactor. Iii The Inhibiting Effect Of An Inert Species, Mark Nelson Jan 2005

Bifurcation Phenomena For An Oxidation Reaction In A Continuously Stirred Tank Reactor. Iii The Inhibiting Effect Of An Inert Species, Mark Nelson

Faculty of Informatics - Papers (Archive)

We extend an investigation into the static and dynamic multiplicity exhibited by the reaction of a fuel/air mixture in a continuously stirred tank reactor by considering the effect of adding a chemically inert species to the reaction mixture. The primary bifurcation parameter is taken to be the fuel fraction as this is the most important case from the perspective of fire-retardancy. We show how the addition of the inert species progressively changes the steady-state diagrams and flammability limits. We also briefly outline how heat-sink additives can be incorporated into our scheme.

Improving Bioreactor Performance: Are Two Cstbs Always Better Than One?, Harvinder Sidhu, Mark Nelson Jan 2005

Improving Bioreactor Performance: Are Two Cstbs Always Better Than One?, Harvinder Sidhu, Mark Nelson

Faculty of Informatics - Papers (Archive)

We investigate a bioreactor cascade consisting of two reactors. For a given total residence time, we study how the performance of the reactor (measured either as the cell mass concentration or the reactor productivity) depends upon the feed substrate concentration and the residence time in the first reactor. The bioreactor model in this study uses a growth rate that is given by a Monod expression with a yield coefficient that is a linear function of the substrate concentration. Previous researchers have compared the performance o f a two-reactor system against a single reactor with the same total residence time. The …

Analysis Of The Michaelis-Menten Mechanism In An Immobilised Enzyme Reactor, Mark Nelson, Xiao Dong Chen, M. J. Sexton Jan 2005

Analysis Of The Michaelis-Menten Mechanism In An Immobilised Enzyme Reactor, Mark Nelson, Xiao Dong Chen, M. J. Sexton

Faculty of Informatics - Papers (Archive)

We investigate the behaviour of a reaction described by Michaelis-Menten kinetics in an immobilised enzyme reactor (IER). The IER is treated as a well-stirred flow reactor, with the restriction that bounded and unbounded enzyme species are constrained to remain within the reaction vessel. Our aim is to identify the best operating conditions for the reactor. The cases in which an immobilised enzyme reactor is used to either reduce pollutant emissions or to synthesise a product are considered. For the former we deduce that the reactor should be operated using low flow rates whereas for the latter high flow rates are …

Distance Education Teaching And Tutoring: Two Evolving Australian Models, A. Fuller, Penelope Mcfarlane, Patricia Cretchley, Christine Mcdonald, Cam Le Lam Jan 2005

Distance Education Teaching And Tutoring: Two Evolving Australian Models, A. Fuller, Penelope Mcfarlane, Patricia Cretchley, Christine Mcdonald, Cam Le Lam

Faculty of Informatics - Papers (Archive)

Many Australian universities have entered the distance education market, offering degree programs throughout South East Asia. Although each university offers their programs in a variety of styles, the common factor is the use of computer and web based technologies to not only support the subject’s content, but to facilitate the communication between the students and their academics. Students have accepted this mode of delivery through the presence of their local academics, who have facilitated their use of the technology. Without their local input, both academically and culturally, it can be seen that student use of computer based technology would be …

Embedded Lossless Audio Coding Using Linear Prediction And Cascade, Kevin Adistambha, Christian Ritz, Jason Lukasiak Jan 2005

Embedded Lossless Audio Coding Using Linear Prediction And Cascade, Kevin Adistambha, Christian Ritz, Jason Lukasiak

Faculty of Informatics - Papers (Archive)

Embedded lossless audio coding is a technique for embedding a perceptual audio coding bitstream within a lossless audio coding bitstream. This paper provides an investigation into a lossless embedded audio coder based on the AAC coder and utilising both backward Linear Predictive Coding (LPC) and cascade coding. Cascade coding is a technique for entropy coding of large dynamic range integer sequences that has the advantage of simple implementation and low complexity. Results show that employing LPC in an embedded architecture achieves approximately an 8% decrease in the coding rate. The overall compression performance of cascade coding closely follows Rice coding, …

Knowledge-Based Semantic Image Segmentation And Global Precedence Effect, Fardin Akhlaghian Tab, Golshah Naghdy Jan 2005

Knowledge-Based Semantic Image Segmentation And Global Precedence Effect, Fardin Akhlaghian Tab, Golshah Naghdy

Faculty of Informatics - Papers (Archive)

This paper introduces a knowledge-based semantic image segmentation which extracts the "object(s)-of-interest" from the image. Image templates are the high-level knowledge in the system. The major contribution of this work is the use of the "Global Precedence Effect" (forest before trees) of the human visual system (HVS) in image analysis and understanding. The "object-of-interest" is searched for hierarchically through an irregular pyramid by an affine invariant comparison between the different region combinations and the template starting from lowest to the highest resolutions. The global/large size objects are found at lower resolutions with significantly lower computational complexity.

Certificateless Public Key Encryption Without Pairing, Joonsang Baek, R. Safavi-Naini, Willy Susilo Jan 2005

Certificateless Public Key Encryption Without Pairing, Joonsang Baek, R. Safavi-Naini, Willy Susilo

Faculty of Informatics - Papers (Archive)

“Certificateless Public Key Cryptography” has very appealing features, namely it does not require any public key certification (cf. traditional Public Key Cryptography) nor having key escrow problem (cf. Identity-Based Cryptography). Unfortunately, construction of Certificateless Public Key Encryption (CLPKE) schemes has so far depended on the use of Identity-Based Encryption, which results in the bilinear pairing-based schemes that need costly operations. In this paper, we consider a relaxation of the original model of CLPKE and propose a new CLPKE scheme that does not depend on the bilinear pairings. We prove that in the random oracle model, our scheme meets the strong …
