Price And Non-Price Influences On Water Conservation: An Econometric Model Of Aggregate Demand Under Nonlinear Budget Constraints, Leonardo Corral, Anthony C. Fisher, Nile W. Hatch

Faculty Publications

This paper develops a model of residential water demand under a nonlinear budget constraint. The theoretical model for an individual consumer is adapted to yield an aggregate model that preserves the structure of the individual demand function, and that can be used with aggregate (water district level) data. The model is used to study the influence of pricing and non-price conservation programs on consumption and conservation behavior in three water districts in the San Francisco Bay Area, over a 10-year period that includes both drought and normal years. Empirical results show that pricing can be effective in reducing water consumption, …

Harp: A Distributed Query System For Legacy Public Libraries And Structured Databases, Ee Peng Lim, Ying Lu

Research Collection School Of Computing and Information Systems

The main purpose of a digital library is to facilitate users easy access to enormous amount of globally networked information. Typically, this information includes preexisting public library catalog data, digitized document collections, and other databases. In this article, we describe the distributed query system of a digital library prototype system known as HARP. In the HARP project, we have designed and implemented a distributed query processor and its query front-end to support integrated queries to preexisting public library catalogs and structured databases. This article describes our experiences in the design of an extended Sequel (SQL) query language known as HarpSQL. …

Making Sharing Pervasive: Ubiquitous Computing For Shared Note Taking, James A. Landay, Richard C. Davis

Research Collection School Of Computing and Information Systems

As a variety of low-cost note-taking devices becomes pervasive, shared notes can help work groups better communicate ideas and information. To explore this idea further, we carried out three related case studies of how members of a large research group shared meeting notes. The group found value in combining personal notes and presentation slides with a single, unifying document, such as regular meeting minutes. The minutes provided structure when there were too many sources of notes. We used this insight in our design of NotePals, a note-sharing system with a lightweight process, an interface, and hardware that distinguish it from …

Measurement Of W-Pair Production In E+E- Collisions At 183 Gev, R. Barate, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

The production of W+W− pairs is analysed in a data sample collected by ALEPH at a mean centre-of-mass energy of 182.7 GeV, corresponding to an integrated luminosity of 57 pb−1 . Cross sections are given for different topologies of W decays into leptons or hadrons. Under Standard Model assumptions for the W-pair production and decay, the W-pair cross section is measured to be 15.57 ± 0.62(stat.) ± 0.29(syst.) pb. Using also the W-pair data samples collected by ALEPH at lower centre-of-mass energies, the decay branching ratio of the W boson into hadrons is measured to be B(W → hadrons) = …

Search For Invisible Higgs Boson Decays In E+E- Collisions At Centre-Of-Mass Energies Up To 184 Gev, R. Barate, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

In a data sample of 78.3 pb−1 collected in 1996 and 1997 by the ALEPH detector at centre-of-mass energies from 161 to 184 GeV, invisible decays of a Higgs boson have been searched for in the reaction e+e− → hZ, where the Z can decay into e+e−, µ+µ− or q¯q. No evidence for a signal is found and limits on the production cross section are derived as a function of the Higgs boson mass. These results are combined with those obtained in an update of the analyses of the ALEPH data taken at LEP 1. For a production cross section …

Measurement Of The Hadronic Photon Structure Function At Lep 1 For 〈Q2〉 Values Between 9.9 And 284 Gev2, Barate, R.; Et Al., M. Thulasidas

Research Collection School Of Computing and Information Systems

Inclusive γ∗γ interactions to hadronic final states where one scattered electron or positron is detected in the electromagnetic calorimeters have been studied in the LEP 1 data taken by ALEPH from 1991 to 1995. The event sample has been used to measure the hadronic structure function of the photon F2γ in three bins with 〈Q2〉 of 9.9, 20.7 and 284 GeV2.

Measurement Of The W Mass In E+E- Collisions At 183 Gev, Barate, R.; Et Al., M. Thulasidas

Research Collection School Of Computing and Information Systems

The mass of the W boson is obtained from reconstructed invariant mass distributions in W-pair events. The sample of W pairs is selected from 57 pb−1 collected with the ALEPH detector in 1997 at a centre-of-mass energy of 183 GeV.

Search For The Standard Model Higgs Boson At The Lep2 Collider Near √S = 183 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

During 1997 the ALEPH experiment at LEP gathered 57pb−1 of data at centre-of-mass energies near 183 GeV. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction e+e−→HZ. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: mH>87.9GeV/c2 at 95% confidence level.

Determination Of |Vub| From The Measurement Of The Inclusive Charmless Semileptonic Branching Ratio Of B Hadrons, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

From a study of the kinematic properties of the final state produced in the semileptonic decays b→Xℓνℓb→Xℓνℓ, the inclusive charmless semileptonic branching ratio of b hadrons is measured. With a sample of 3.6 million hadronic Z decays recorded between 1992 and 1995 with the ALEPH detector at LEP, the value Br(b→Xuℓνℓ)Br(b→Xuℓνℓ) is determined to be (1.73±0.55stat±0.55syst)×10−3(1.73±0.55stat±0.55syst)×10−3, where XuXu represents any charmless hadronic state and b is a mixture of b hadrons weighted by their production rates. This measurement yields the result|Vub|2=(18.68±5.94stat±5.94syst±1.45HQE)×10−6,|Vub|2=(18.68±5.94stat±5.94syst±1.45HQE)×10−6,where the last error comes from the conversion of the branching ratio to the CKM matrix element squared.

Search For Supersymmetry With A Dominant R-Parity Violating Lqd̄ Coupling In E+E- Collisions At Centre-Of-Mass Energies Of 130 Gev To 172 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LQD¯LQD¯ coupling has been performed using the data collected by ALEPH at centre-of-mass energies of 130–172 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation. This result is translated into lower limits on the masses of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, for m0=500m0=500 GeV/c2/c2 and tanβ=2–√tan⁡β=2 charginos with masses smaller than 81 GeV/c2/c2 and neutralinos with masses smaller than 29 GeV/c2/c2 are excluded at the 95% confidence level for any generation structure of …

Decision Analytic Approach To Severe Head Injury Management., Harmanec D., Tze-Yun Leong, Sundaresh S., Poh K., Yeo T., Ng I., Lew T.

Research Collection School Of Computing and Information Systems

Severe head injury management in the intensive care unit is extremely challenging due to the complex domain, the uncertain intervention efficacies, and the time-critical setting. We adopt a decision analytic approach to automate the management process. We document our experience in building a simplified influence diagram that involves about 3000 numerical parameters. We identify the inherent problems in structuring a model with unclear domain relationships, numerous interacting variables, and real-time multiple inputs. We analyze the effectiveness and limitations of the decision analytic approach and present a set of desiderata for effective knowledge acquisition in this setting. We also propose a …

A Submersible Battery-Powered Flow Injection (Fi) Sensor For The Determination Of Nitrate In Estuarine And Coastal Waters., Anthony R.J. David, Trevor Mccormack, Paul J. Worsfold

School of Geography, Earth and Environmental Sciences

The design, construction and performance of a remotely deployed submersible flow injection-based nutrient (total oxidized nitrogen) sensor are described. The sensor featured a custom-built microcomputer and a solid-state, flow-through spectrophotometric detector, and the derivatization chemistry was based on in-line copper-cadmium reduction of nitrate to nitrite, and diazotization with N1NED and sulphanilamide. The limit of detection was 0.0014 mg l(-1) NO3-N and the linear range was 0.0014- 0.77 mg l(-1) with a 260 microl sample volume and a 20 mm path length flow cell. Results from submersed deployments in the Tamar estuary and North Sea are also reported.

Psychological Assessment For The Courts : A Survey Of Psychologists, Mary-Anne Martin

Theses: Doctorates and Masters

The literature relevant to legal standards in criminal, family, and civil settings in relation to psychological assessments for the courts is reviewed. Although over the past twenty years, a number of specialised forensic instruments have been developed for use in forensic settings, it appears that they are infrequently used. Surveys of test use patterns reveal that psychological test use in forensic settings is virtually identical to that in clinical settings, despite the different nature of the referral questions. The debate about the use of psychological tests in forensic assessments, and research on the use of tests in these assessments is …

Astride Two Worlds: The Chinese Response To Changing Citizenship In Western Australia (1901-1973), Tian M. Cai

Theses: Doctorates and Masters

Citizenship is central to understanding the nature of Chinese migrants and their relationships within the social and political environment in Australia. Utilising the concept of citizenship can be a new way to interpret the human experience of the Chinese survival in Australia and to show that a historical balance can be found between the Australian social environment on the one side and the Chinese experience in Australia on the other. How the Chinese community reacted to the changing issues in citizenship and attitudes towards Asian immigration become the focus of the thesis. This research is designed to ask how Chinese …

Fourth World Consumer Culture: Emerging Consumer Cultures In Remote Aboriginal Communities Of North-Western Australia, Ronald George Groves

Theses: Doctorates and Masters

Over the two centuries since the arrival of European settlers in Australia, the material culture and lifestyle of the indigenous Aboriginal people of Australia has undergone dramatic change. Based on qualitative fieldwork in three remote Aboriginal communities in north-western Australia, this study examines the emergence of unique consumer cultures that appear to differ significantly from mainstream Australia and indeed from other societies. The study finds that the impact of non-indigenous goods and external cultural values upon these communities has been significant. However, although anthropologists feared some fifty years ago that Aboriginal cultural values and traditions had been destroyed, this study …

Centred Voices : A Study Of The Lived Experience Of Women's Health Centre Coordinators, Jodie L. Moyle

Theses: Doctorates and Masters

The purpose of this phenomenological study is to explore and describe the lived experience of women's health centre coordinators. In addition to the intrinsic value of telling these women's stories, this research provides data which can he used to strengthen the economic, political, organisational and social position of women’s health centres and the women who work in them. Four women managers from regional urban women's health centres in Australia were interviewed about their subjective experiences with respect to their current working roles. Interviews were audio taped, transcribed and coded to produce themes and to preserve anonymity. Data was analysed using …

Malpractice And The Tax Practitioner: An Analysis Of The Areas In Which Malpractice Occurs, Jacob L. Todres

Faculty Publications

(Excerpt)

As an attorney for approximately twenty-five years, I have been cognizant of the apparent increase in litigiousness of modem society, and of the concomitant increase in malpractice suits against professionals, both lawyers as well as non-lawyers. As a teacher of tax law, I am especially interested in how this trend impacts the tax lawyer, as well as other tax practitioners. What I am especially interested in is determining which areas of tax law and tax practice have generated the most malpractice claims so that practitioners may embark into such areas forewarned. Unfortunately, most of the existing literature focuses on …

Efficient Dynamic Unstructured Methods And Applications For Transonic Flows And Hypersonic Stage Separation, Xiaobing Luo

Mechanical & Aerospace Engineering Theses & Dissertations

Relative-moving boundary problems have a wide variety of applications. They appear in staging during a launch process, store separation from a military aircraft, rotor-stator interaction in turbomachinery, and dynamic aeroelasticity.

The dynamic unstructured technology (DUT) is potentially a strong approach to simulate unsteady flows around relative-moving bodies, by solving time-dependent governing equations. The dual-time stepping scheme is implemented to improve its efficiency while not compromising the accuracy of solutions. The validation of the implicit scheme is performed on a pitching NACA0012 airfoil and a rectangular wing with low reduced frequencies in transonic flows. All the matured accelerating techniques, including the …
