Constrained Moments Simulation Of Healthcare Capital Acquisitions, A. Narsing, Samuel Frimpong, J. Whiting Jan 1997

Constrained Moments Simulation Of Healthcare Capital Acquisitions, A. Narsing, Samuel Frimpong, J. Whiting

Mining Engineering Faculty Research & Creative Works

Summary form only as given. Two analytical techniques which evaluate capital acquisitions in healthcare are the method of generating system moments and Monte Carlo simulation. Generating system moments enables the user to determine an estimate of the expected cost from a user-supplied function. Furthermore, the user can determine, from a variance component analysis, the sensitivity of the user-supplied function to marginal changes in the random variables by expanding the function about its mean using the Taylor series expansion to the second order. Calculating the magnitude of partial derivatives of each random variable with respect to the user-supplied function indicates the …

Scaling Parallels In The Non-Debye Dielectric Relaxation Of Ionic Glasses And Dipolar Supercooled Liquids, David L. Sidebottom, Peter F. Green, Richard K. Brow Jan 1997

Scaling Parallels In The Non-Debye Dielectric Relaxation Of Ionic Glasses And Dipolar Supercooled Liquids, David L. Sidebottom, Peter F. Green, Richard K. Brow

Materials Science and Engineering Faculty Research & Creative Works

We compare the dielectric response of ionic glasses and dipolar liquids near the glass transition. Our work is divided into two parts. In the first section we examine ionic glasses and the two prominent approaches to analyzing the dielectric response. The conductivity of ion-conducting glasses displays a power law dispersion σ(ω)∞ωn, where n≈0.67, but frequently the dielectric response is analyzed using the electrical modulus M*(ω) = 1/ε*(ω), where ε*(ω) = ε(ω) - iσ(ω)/ω is the complex permittivity. We reexamine two specific examples where the shape of M*(ω) changes in response to changes in (a) temperature and (b) ion concentration, to …

Ferroelectric Films As A Fashion Object For Polycrystalline Film Investigation, V. Petrovsky, Harlan U. Anderson, M. Shumsky Jan 1997

Ferroelectric Films As A Fashion Object For Polycrystalline Film Investigation, V. Petrovsky, Harlan U. Anderson, M. Shumsky

Materials Science and Engineering Faculty Research & Creative Works

BaxSr1-xTiO3 (BST), PbZrxTi1-xO3 (PZT) and two-layer PZT-BST films were prepared on Pt, Si(100) and Si(111) substrates by a sol-gel method. XRD analysis shows that the PZT films on the Si(111) substrates tended to be preferentially oriented in the (110) direction. The nondestructive readout of the state of ferroelectric polarization was investigated by three methods: the pyroelectric effect, the non-linearity of the capacitance and the field effect in MOS structures. It is shown that all three methods provide nondestructive readout, and the choice between them depends on the intended use.

Chemical Durability Of Lead-Oxide-Based, Thick-Film Binder Glasses, Douglas M. Mattox, Joshua H. Robinson Jan 1997

Chemical Durability Of Lead-Oxide-Based, Thick-Film Binder Glasses, Douglas M. Mattox, Joshua H. Robinson

Materials Science and Engineering Faculty Research & Creative Works

Lead-oxide-bearing glasses are incompatible with aluminum nitride metallization's, and federal legislation is recommending their replacement in thick-film electronics and labeling. To evaluate alternatives, the benchmark chemical durability's of the lead borosilicate and lead aluminate thick-film binder glasses have been determined. Aluminum oxide (Al2O3) benefits water durability moderately, acid durability substantially, and basic durability indistinguishably. The rate of attack in water is approximately two orders of magnitude greater than for soda-lime glass. The thermal contractions of the glasses are compatible. An apparent, spontaneous phase separation in the Al2O3-free glass is suppressed by Al2O3 that is included as a batch component.

Physics Faculty Research & Creative Works

Aircraft-based measurements of sulfur dioxide, acetone, carbon dioxide, and condensation nuclei (CN) were made over the north-eastern Atlantic at upper tropospheric altitudes, around 9000 m. On October 14, 1993, strong SO 2- and acetone-pollution (both up to 3 ppbv) were observed, which were accompanied by a CO 2-enhancement of up to 6 ppmv, and large CN-concentrations of up to about 1500 cm -3 (for radii ≥ 6 nm). CN, excess CO 2, and to a lesser degree also acetone, were positively correlated with SO 2. Air mass trajectory analyses indicate, that most of the air masses …

Spherical Harmonics - Finite Element Treatment Of Neutron Transport In Cylindrical Geometry, Hatem Khouaja, D. Ray Edwards, Nicholas Tsoulfanidis Jan 1997

Spherical Harmonics - Finite Element Treatment Of Neutron Transport In Cylindrical Geometry, Hatem Khouaja, D. Ray Edwards, Nicholas Tsoulfanidis

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

A variational spherical harmonics (DPN) method is used in conjunction with the finite element method to solve the transport of neutron beams. The method is developed for finite axisymmetric cylindrical geometry. In this model, the angular distribution along the path of neutron travel is separated into two sub-ranges of the forward and the backward moving particles. The system of the model equations is cast in terms of an even and an odd vector analogue to the even-parity transport technique. The finite element method is applied in space to solve the resulting coupled system of equations. A source-free cylinder with specified …

The Development Of Novel Techniques For Characterisation Of Marine Zooplankton Over Very Large Spatial Scales, Christopher Paul Gallienne Jan 1997

The Development Of Novel Techniques For Characterisation Of Marine Zooplankton Over Very Large Spatial Scales, Christopher Paul Gallienne

School of Biological and Marine Sciences Theses

Marine zooplankton play an important role in the transfer of CO2 from the atmosphere/ocean system to deeper waters and the sediments. They also provide food for much of the world's fish stocks and in some areas of the ocean depleted of nutrients they sustain phytoplankton growth by recycling nutrients. They therefore have a profound effect on the carbon cycle and upon life in the oceans. There is a perceived lack of information about global distributions of zooplankton needed to validate ecosystems dynamics models, and the traditional methods of survey are inadequate to provide this information. There is a need to …

A Design In Interfacing The Mc68hc11 To The Amd Am29f010 Flash Memory Chips, David H. Hands Jan 1997

A Design In Interfacing The Mc68hc11 To The Amd Am29f010 Flash Memory Chips, David H. Hands

Theses : Honours

In many environments, motion, vibration and contamination to the Secondary Storage Devices such as hard drives can cause data to become unreadable or even lost. Elimination of these types of magnetic drives, incorporating its replacement with a Solid State Memory Storage Device would provide an invaluable solution for these type of environments. If a secondary storage system could replace these electro-mechanical disk drive systems incorporating a Solid State Secondary Storage Device such as the Flash Memory Integrated Chips, an increase in the speed of reading from milli-seconds to nano-seconds would transpire as well as providing a robust Secondary Storage Device. …

Design And Implementation Of High-Radix Arithmetic Systems Based On The Sdnr/Rns Data Representation, Paul Whyte Jan 1997

Design And Implementation Of High-Radix Arithmetic Systems Based On The Sdnr/Rns Data Representation, Paul Whyte

Theses : Honours

This project involved the design and implementation of high-radix arithmetic systems based on the hybrid SDNRIRNS data representation. Some real-time applications require a real-time arithmetic system. An SDNR/RNS arithmetic system provides parallel, real-time processing. The advantages and disadvantages of high-radix SDNR/RNS arithmetic, and the feasibility of implementing SDNR/RNS arithmetic systems in CMOS VLSI technology, were investigated in this project. A common methodological model, which included the stages of analysis, design, implementation, testing, and simulation, was followed. The combination of the SDNR and RNS transforms potential complex logic networks into simpler logic blocks. It was found that when constructing a SDNRIRNS …

Roundtable Discussion, Joseph W. Dellapenna, Laurelyn Douglas, Ted Hagelin, Edwin L.-C. Lai, Harold G. Maier, Yu Ping, John M. Rogers, Ying J. Rogers, Peter Wesley-Smith

Vanderbilt Journal of Transnational Law

What we are trying to do in this meeting is to predict what Hong Kong is going to become. One thing of which we can be fairly confident is that we can't know now what Hong Kong will become. Yet speculating is often worthwhile, and so this morning I've asked Peter [Wesley-Smith] and I gave him two minutes' warning--to continue what he had done at the outset of yesterday's sessions. You'll remember that he described a history of the relationship among Hong Kong, various treaties, and what is now the People's Republic of China (hereinafter P.R.C.). I've asked Peter if …

Walter Heller's Ambiguous Legacy, Amy Rehder Harris Jan 1997

Walter Heller's Ambiguous Legacy, Amy Rehder Harris

Draftings In

Walter Heller's economic leadership within the political realm opened a Pandora's Box for politicians in Washington and for the American public. As Chair of the Council of Economic Advisers (CEA) during the Kennedy administration, Heller was able to introduce Keynesian economics into the political mainstream and oversee the passage of the first federal tax cuts for the purpose of stimulating demand and economic growth. In the process, however, Heller helped remove politicians' historical reservations regarding budget deficits, setting the stage for today's staggering deficit problem.

The Effects Of Concurrent Strength And Muscular Endurance Resistance Training On Strength, Endurance And Body Composition In Previously Untrained Females, Derek W. Gibbins Jan 1997

The Effects Of Concurrent Strength And Muscular Endurance Resistance Training On Strength, Endurance And Body Composition In Previously Untrained Females, Derek W. Gibbins

Theses : Honours

The number of females engaged in some form of sporting activity is growing rapidly, but many women still shy away from weight training because of their fear of excessive muscular hypertrophy and its accompanying loss of femininity. Because strength and muscular endurance play a vital role in most sporting endeavours, and weight training has proven to be one of the most effective methods to improve both attributes, any training regime that could achieve concurrent increases in both measures without noticeable increases in muscle size would be ideally suited to most women. Changes in strength and endurance resulting from eight weeks …

The Foraging Ecology And Habitat Selection Of The Yellow-Plumed Honeyeater (Lichenostomus Ornatus) At Dryandra Woodland, Western Australia, Kellie Wilson Jan 1997

The Foraging Ecology And Habitat Selection Of The Yellow-Plumed Honeyeater (Lichenostomus Ornatus) At Dryandra Woodland, Western Australia, Kellie Wilson

Theses : Honours

The foraging ecology and habitat selection of the Yellow-plumed Honeyeater was examined using observations and vegetation surveys at Dryandra Woodland, Western Australia. Foraging ecology data was collected over three seasons (autumn, winter and spring) in 1997 at three sites within Dryandra. Habitat selection studies involved 156 sites being surveyed for the presence or absence of the Yellow-plumed Honeyeater. The vegetation characteristics of the site were measured. Yellow-plumed Honeyeaters foraged by gleaning foliage most of the time. Bark and aerial foraging were also common. Birds clearly selected for tree height, preferring to forage on larger (older) trees which may be because …

The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges Jan 1997

The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges

Theses : Honours

Conventional agricultural practices (tillage, extensive application of synthetic fertilisers and biocides) exert substantial disturbance on soil ecosystems, consequently causing severe land degradation through loss of soil organic matter. These practices also place significant pressure on the soil inhabitants. However, permaculture systems practice non-tillage and extensive mulching. These non-tillage practices reduce the amount of perturbation on the litter invertebrates and encourage their abundances. The aims of this study were to describe the above-ground mesofaunal communities in the mulch layer of selected urban permaculture systems in the Perth Metropolitan area. This included determining the faunal abundance and diversity. Four permaculture sites were …

The Role Of Fas And Fas Ligand In Apoptosis During Regression Of The Corpus Luteum, Sharon Roughton Jan 1997

The Role Of Fas And Fas Ligand In Apoptosis During Regression Of The Corpus Luteum, Sharon Roughton

Theses : Honours

Apoptosis, a form of physiological cell death, has been found to occur during regression of the corpus luteum (Juengel etal, 1993; Dharmarajan etal, 1994). The pathways involved in this process, however, have yet to be specified. One possible mediator of corpus luteum regression is the Fas (or AP0-1 or CD95) receptor, a transmembrane protein which induces apoptosis in the cell when ligated. In order to further confirm this hypolhesis, the present study establishes and quantitates the presence and regulation of Fas receptor and Fas ligand (Fasl) in the rat corpus luteum during pregnancy and post-partum. The animals used were sexually …

Genealogical Studies Of Selected Australian Barramundi (Lates Calcarifer) Using Mtdna : Implications For Stock Transfer To The Kimberley Region Of Western Australia, Robert G. Doupe Jan 1997

Genealogical Studies Of Selected Australian Barramundi (Lates Calcarifer) Using Mtdna : Implications For Stock Transfer To The Kimberley Region Of Western Australia, Robert G. Doupe

Theses : Honours

This study resulted from concerns for the present and proposed movement of barramundi (Lates catcarifer) across presumed population genetic boundaries into the Kimberley region of Western Australia for net-pen aquaculture and a recreational fishery development in dams no longer available to seasonal barramundi dispersal. Direct DNA sequencing of the non-recombining, maternally inherited mitochondrial genome of barramundi thought to represent wild populations from a broad section of a still wider Australian range were used for phylogenetic reconstructions that support hypotheses for historic gene flow between Kimberley and other populations during Recent sea level fluctuations. Nil or low levels of genetic diversity …

An Evaluation Of The Productivity Of Two Oil Mallee Species In A Revegetation Trial In The Central Wheatbelt Of Western Australia, Beatrice Lucie Hedwig Franke Jan 1997

An Evaluation Of The Productivity Of Two Oil Mallee Species In A Revegetation Trial In The Central Wheatbelt Of Western Australia, Beatrice Lucie Hedwig Franke

Theses : Honours

Two of Western Australia's most pressing land degradation problems are waterlogging and increasing soil salinity. Extensive clearing of the native. deep-rooted vegetation and its replacement with shallow-rooted crop and pasture plants has resulted in increased recharge of groundwater tables. causing them to rise. Salts stored in the soil are being brought to the soil surface with the rising watertables. Revegetation with deep-rooted native plants has been identified as the most likely strategy to achieve increased groundwater usage and a lowering of watertables. One area seriously affected by waterlogging and increasing salinity is the Western Australian central wheatbelt region. The Department …

Security Decay: The Erosion Of Effective Security, Shawn A. Mcclure Jan 1997

Security Decay: The Erosion Of Effective Security, Shawn A. Mcclure

Theses : Honours

The discipline of security lacks formal conceptual tools which can be used by security managers, advisers and consultants when attempting to provide effective security. This is because of security's relative age as a discipline, it is very new. The aim of the thesis was to contribute to the security discipline by taking Underwood's ( 1989) idea of security decay and to a certain extent exploring and formalising it. The security decay theory is primarily concerned with the influence apathy has on security and how management react to risk materialisation when decay is evident. The thesis focused on the first of …

Coastal Zone Monitoring And Evaluation : A Descriptive Analysis Of Western Australian Practices, Michael F. Williams Jan 1997

Coastal Zone Monitoring And Evaluation : A Descriptive Analysis Of Western Australian Practices, Michael F. Williams

Theses : Honours

Currently there is no information available which documents the monitoring and evaluation practices undertaken in the coastal zone of Western Aust1alia by coastal zone managers. A review of current Australian-wide management practices in coastal management reveals that monitoring and evaluation are limited in their application. The adequacy of the links between coastal monitoring and evaluation, on which our understanding of the state of the coastal zone environment is based, is one of two central themes throughout this research. The other theme is that without an accurate, reliable and effectively managed monitoring and research information base, coastal management will be haphazard …

Comparative Salt And Waterlogging Tolerance Of An Introduced Grass (Agropyron Elongatum [Host] P. Beauv.) And Two Herbaceous Australian Species (Podolepis Gracilis [Lehm.] And Danthonia Caespitosa Gaud.), Bryan William Duff Jan 1997

Comparative Salt And Waterlogging Tolerance Of An Introduced Grass (Agropyron Elongatum [Host] P. Beauv.) And Two Herbaceous Australian Species (Podolepis Gracilis [Lehm.] And Danthonia Caespitosa Gaud.), Bryan William Duff

Theses : Honours

Increasing land degradation is recognised as an immediate worldwide threat. Human induced soil salinity is probably the major cause of land abandonment, through its adverse effects on plant growth. Salinity is a major focus of environmental researchers because it is recognised that counter-strategies can potentially reclaim both artificially degraded lands and intrinsically saline areas. Currently, strategies to combat salinity require that land use is changed, since restoration to a past use is usually economically impractical or impossible. Biological strategies show most promise. Revegetation of degraded soils with hardy plant species has met with considerable success, and shows promise for the …

Does Good Project Management Ensure Successful Software Development?, Julie Lisa Eldridge

Theses : Honours

For many years the development of computer software has been plagued by poor customer satisfaction caused by missed schedules, underestimated budgets and the development of products which do not meet requirements. The ever increasing reliance on computers, as reported by Sommerville ''the result of the proliferation of computer systems into all aspects of life and business is that personal, corporate, national and international economies are [becoming] increasingly dependant on computers and software systems" ( 1992, p.2), calls for more stable software which can be developed within time and budget constraints. To achieve this, software development activities must be analysed and …
